We Asked 10 RDs What Probiotic Supplements They Recommend for Women — Here’s What They Said

A healthy gut can have a ripple effect on your immune system, mood, hormones, weight, and more. For women, gut health is particularly important, since it plays a key role in hormonal balance, digestion, vaginal, and immune health. One potentially effective way to support a healthy gut is to take probiotic supplements.

Probiotics, often called the “good bacteria,” continue to garner the attention of health-conscious consumers. “Taking probiotics through fermented foods or supplements can replenish beneficial bacteria and restore gut balance, leading to improved digestion and overall wellness,” says Lauren Manaker, RDN, the owner of Nutrition Now Counseling in Charleston, South Carolina.

It’s important to note that pre-, pro-, and postbiotics are still an active area of research and there’s more work to be done to clarify which specific conditions and intentions would be most supported by specific strains and formulations.

Let’s dive into the best probiotics for women recommended by our experts and the key factors to consider when choosing a probiotic to fit your needs.

Our Top Picks for the Best Probiotics for Women

When to Consult Your Doctor

Everyday Health recommends speaking with your doctor before adding any supplement to your diet to make sure it is safe and appropriate for your individual health needs. Consult your doctor or healthcare provider if you have a weakened immune system, are on immunosuppressant drugs, or have another critical illness. If your immune system is weakened by illness or medications, you’re more likely to experience interactions or illness from taking probiotics. In addition, if you’re pregnant or breastfeeding, consult your obstetrician-gynecologist (ob-gyn) for specific recommendations.

Best Probiotic With Prebiotics

Culturelle 4-in-1 Probiotics for Women

$22.99 at Walmart
$24.98Now 8% Off

Pros

  • Contains five probiotic strains
  • Has undergone clinical trials
  • Contains prebiotic and probiotic

Cons

  • Bad taste
  • Some users report severe bloating
  • Prebiotics can cause gas
  • CFU count: 15 billion
  • Probiotic strains: Proprietary blend of lactobacillus strains
  • Other ingredients: Prebiotic blend
  • Serving size: 1 capsule
  • Form: Capsules
  • Third-party tested: No

Culturelle 4-in-1 Probiotics for Women contains five research-studied probiotic strains to support women’s vaginal, urinary, digestive, and immune health.

“Not only does Culturelle's 4-in-1 probiotic promote a healthy gut microbiome, it also helps support vaginal and urinary health,” says Megan Huff, RD, the owner of Nutrition by Megan in Atlanta. “It contains 15 million colony-forming units (CFUs) of a probiotic blend, including L. crispatus, which has been shown to reduce discharge and vaginal itching and irritation,” she adds.

The CFU count of a probiotic is a measure of its potency. Probiotic potency may range from one billion to 200 billion CFUs.

 Lactobacillus crispatus may further support vaginal health as it is associated with fewer abnormal Pap smears.

In addition, lab studies showed that lactobacillus strains, including the L. gasseri and L. crispatus used in this Culturelle product, have a strong antibacterial effect on the multidrug-resistant indicator strains tested, suggesting that the lactobacillus strains may offer protection against urinary tract infections, which occur in 1 in 3 women at some point in their life, though further studies need to be done to say for sure.

This supplement also includes 15 milligrams (mg) of a prebiotic blend, which not all probiotic supplements offer. Prebiotics are beneficial fibers that nourish the probiotic bacteria and can improve their effectiveness.

Just be aware that sometimes, prebiotics can “sometimes trigger symptoms in people sensitive to certain carbohydrates, known as FODMAPs,” says Cheryl Harris, MPH, RD, the owner of Harris Whole Health in Burke, Virginia.

We also like that Culturelle probiotics have been used in multiple clinical studies, and the company’s processes are audited regularly by NSF International. The National Sanitation Foundation (NSF) is a reputable third-party testing company that certifies a supplement’s quality and safety.

Best for Bloating

Align Probiotics Bloating Relief and Food Digestion

$25.95 at Walmart
$40.95Now 37% Off

Pros

  • Contains a clinically studied probiotic strain for bloat
  • Includes a digestive enzyme blend
  • Adds B12 to break down food

Cons

  • Some customers reported gas and bloating
  • CFU count: 1 billion
  • Probiotic strains: Bifidobacterium 35624 TM
  • Other ingredients: B12, digestive enzyme blend
  • Serving size: 1 capsule
  • Form: Capsule
  • Third-party tested: Yes
Align Probiotic Bloating Relief contains one billion CFU of a single probiotic strain for bloating, a symptom more commonly reported in women than men.

While there’s no universal CFU count recommended, a minimum of one billion CFUs is the potency seen to show benefits in research studies, and more may be recommended for certain uses according to your doctor’s recommendations.

It also contains added digestive enzymes and vitamin B12, which may help further break down food for more efficient digestion. The strain present is Bifidobacterium longum 35624 (B. longum) and was developed by gastroenterologists to soothe occasional gas, bloating, and digestive discomfort.
"I recommend Align Probiotics Bloating Relief and Food Digestion for women dealing with bloating thanks to its use of Bifidobacterium longum 35624, a clinically studied strain shown to improve gut health,” says Emily Hirsch, RD, the owner of South Charlotte Nutrition in Charlotte, North Carolina. “Additionally, it includes the digestive enzymes amylase, protease, lipase, and lactase, which may help reduce symptoms of indigestion such as bloating.”

This supplement also contains vitamin B12, which may help break down our food to facilitate digestion. Research also shows it may positively influence the health of your gut.

A few Amazon customers reported increased bloating and indigestion after taking this product, but this was not across the board. It’s important to remember that individual responses to probiotic supplements can vary, and it’s best to choose one that you can tolerate.

Best for IBS

SFI Health Ther-Biotic Pro IBS Relief

$37.98 at Amazon

Pros

  • Research-studied strains for gut health and IBS
  • Contains gentle prebiotic for sensitive stomachs
  • Third-party tested

Cons

  • Some customers didn’t receive all pills
  • Prebiotics can cause gas
  • CFU count: 20 billion
  • Probiotic strains: 3 strains — L. plantarum, L. acidophilus, L. lactis
  • Other ingredients: InTactic proprietary polysaccharide complex
  • Serving size: 1 capsule
  • Form: Capsule
  • Third-party tested: Yes
If you suffer from irritable bowel syndrome (IBS), SFI Health’s Ther-Biotic Pro IBS Relief is designed to reduce IBS-related symptoms. It contains three key probiotic strains: Lactobacillus plantarum (L. plantarum), Lactobacillus acidophilus (L. acidophilus), and Bifidobacterium lactis (B. lactis), some of the best probiotic strains for IBS-related symptoms and contains a potent dose of 20 billion colony-forming units (CFU).

This product also contains the prebiotic Sunfiber, which is low-FODMAP certified, which means it may be more gentle on the stomach for women with IBS.

But it’s important to keep in mind that individual tolerance to prebiotics can still vary, especially in those with sensitive guts.

SFI Health (formerly Klaire Labs) uses third-party testing to ensure safety and potency. We value their transparency with its product research, linking to several studies under the frequently asked questions (FAQs) section. Not all brands do this, and it adds to its trustworthiness and proof of effectiveness. This probiotic also uses a proprietary technology called “InTactic,” designed to protect the bacteria in the product from stomach acid.

Best for Vaginal Health

Metagenics UltraFlora Women’s

$40.43 at Walmart
$39.60Now -2% Off

    Research suggests probiotics can optimize, maintain, and restore vaginal microflora.

    Metagenics Ultraflora Women’s contains 2 billion CFUs of Lactobacillus strains that are intended to specifically target vaginal health. According to research, Lactobacillus species are one of the most abundant microorganisms in the vaginal microbiome.

    While more studies are needed on the role of probiotics in vaginal health, studies suggest the two strains in this product, Lactobacillus rhamnosus (L. rhamnosus) and Lactobacillus reuteri (L.reuteri), may improve a bacterial imbalance in the vaginal area called vaginal dysbiosis.

    These strains can also help reduce the build-up of harmful bacteria and yeast in the vagina, which may reduce the risk of yeast infections.

    Metagenics has been a well-known brand for over 40 years that conducts regular in-house product testing. It’s also third-party certified by ConsumerLab.com to ensure high quality and safety standards. These probiotics are vegetarian, gluten-free, and dairy-free for sensitive people. Note: The proprietary blend means we don’t know the CFU count of each strain.

    Best for Immunity

    Douglas Laboratories Multi-Probiotics

    $45.60 at Amazon

    Pros

    • Contains multiple probiotic strains for immunity
    • Includes prebiotics
    • CGMP-certified
    • Non-GMO, additive-free
    • Free from common allergens

    Cons

    • CFU count: 40 billion
    • Probiotic strains: Proprietary blend of 16 different Lactobacilli and Bifidobacteria
    • Other ingredients: Prebiotic fiber
    • Serving size: 2 capsules
    • Form: Capsules
    • Third-party tested: Yes
    If you’re looking for a probiotic supplement for a healthy immune system, Douglas Laboratories Multi-Probiotic contains several strains to promote immunity. One of the strains of bacteria used in this probiotic, Lactobacillus planterum, may reduce inflammation and promote a healthy immune system.

    Another primary strain in this probiotic is Lactobacillus acidophilus (L. acidophilus), one of the most researched strains. “L. acidophilus supports gut health and immunity by reducing inflammation in the GI tract and increasing healthy bacteria while reducing the growth of pathogenic (“bad”) bacteria,” says Caitlin Beale, RDN, the owner of Caitlin Beale Wellness in San Francisco.

    This product also contains added Nutraflora prebiotic fiber, a soluble fiber that nourishes immune-supporting probiotics.

     When choosing a probiotic to support your immune system, note that probiotics shouldn’t just be added after you get sick. They are instead intended to be taken regularly before you get sick to allow time for their therapeutic effects to support your overall immunity.

    Note: The proprietary blend means we don’t know the CFU count of each strain.

    In addition, Douglas Laboratories has been in business for 65 years. They conduct regular in-house testing, and their products are CGMP-certified to ensure good manufacturing processes.

    If you follow a vegan lifestyle, Future Kind’s Vegan Probiotic Digestion Supplement is 100 percent vegan. It contains nine bifidobacterium and lactobacillus strains to support a healthy female metabolism, digestion, and immunity, plus Future Kind’s patented strain that has been clinically studied. This product also undergoes regular independent testing, where they share a certificate of analysis on their product page for added peace of mind.

    “Future Kind+ is a 100 percent vegan brand, suitable for plant-based lifestyles. This once-a-day probiotic contains 30 billion CFUs from 10 different strains, including the strain DE111 Bacillus subtilis, which may have particular benefits for cardiovascular health [by supporting vascular function and possibly lowering high LDL],” says Lauren Panoff, MPH, RD, the cofounder of the Food Trends in Denver.

    LDL cholesterol is the “bad” cholesterol that can build up in your arteries over time, especially as women approach menopause.

    “This probiotic contains 30 billion CFUs with multiple evidence-backed strains like Lactobacillus rhamnosus, which supports gut health and helps with IBS, and Bacillus subtilis, a soil-based probiotic that also supports immune health,” adds Beale. It’s also free of all major allergens.

    Note: The proprietary blend means we don’t know the CFUs of each strain.

    NOW Probiotic-10 25 Billion is our top pick for the most budget-friendly probiotic, as it contains 10 research-backed strains, and you can find it for less than $16 for a month’s supply. With Amazon’s subscribe-and-save option, you can get a 30-day supply for less than $13 per month. “This budget-friendly probiotic is under $20 a bottle, making it easy on the wallet. It’s made with a blend of 10 strains of bacteria provided in impressive quantities. And each supplement delivers a potency of 25 billion CFUs through the best-by date,” says Manaker.

    Best for Menopause

    Ora Lady Bugs Probiotics and Prebiotics for Women

    $39.99 at Amazon
    $44Now 9% Off

    Pros

    • Clinically studied strains for vaginal and menopausal health
    • Contains added prebiotics
    • Third-party tested
    • Vegan
    • Dairy, gluten, soy-free

    Cons

    • Probiotic strains: Lactobacillus plantarum (UALp-05TM), Lactobacillus acidophilus (DDS-1), Lactobacillus rhamnosus (LGG), Lactobacillus crispatus (UALcr-35TM), Lactobacillus reuteri (UALre-16TM), Lactobacillus fermentum (UALf-32TM)
    • Other ingredients: Jerusalem artichoke inulin
    • Serving size: 3 capsules
    • Form: Capsules
    • Third-party tested: Yes
    If you want to optimize your health during menopause, a 2023 research review from Current Nutrition Reports highlighted the key roles of a healthy microbiota in menopausal women health and the potential for probiotics to help, including optimizing calcium absorption, reducing cancer risk, reducing menopausal symptoms and supporting healthy weight.

    The combination of probiotic strains and ingredients in Ora Lady Bugs makes it a well-rounded probiotic and prebiotic choice for menopausal health support. “The Lactobacillus reuteri and Lactobacillus rhamnosus strains in this probiotic have shown favorable results for vaginal health in some studies, a key concern during menopause due to estrogen fluctuations,” says Claire Rifkin, RDN, owner of Claire Rifkin Nutrition in New York City.

    “It also includes Jerusalem artichoke inulin, a fiber that some research suggests may aid in bone health and address osteoporosis risk, another common menopausal issue,” she adds.

    This product contains only clean, organic, whole-food ingredients. It’s also vegan and dairy, gluten, and soy-free. It’s important to note that a few users with histamine intolerance reported this product caused flushing and redness of the face in the first few weeks of use.

    Best for Postmenopause

    Garden of Life Dr. Formulated Probiotics Once Daily Women’s

    $30.48 at Amazon
    $39.95Now 24% Off

    Pros

    • Research-backed strains for postmenopausal women
    • Includes prebiotics
    • Third-party tested
    • Made from whole foods

    Cons

    • Contains proprietary blends
    • Prebiotics may cause gas
    • CFU count: 50 billion CFU
    • Probiotic strains: 16 bifidobacterium and lactobacillus strains
    • Other ingredients: N/A
    • Serving size: 1 capsule
    • Form: Capsules
    • Third-party tested: Yes
    Garden of Life’s Dr. Formulated Probiotics Once Daily Women’s is our top pick for postmenopausal health. This higher-potency supplement contains a mix of 16 probiotic strains associated with postmenopausal wellness, such as Bifidobacterium lactis and Lactobacillus acidophilus. It also contains a robust bacterial count of 50 billion CFUs, the highest on our list. “Emerging research shows a potential link between a healthy gut flora and a reduced risk of osteoporosis, particularly in postmenopausal individuals. While evidence varies on specific probiotic strains effective for postmenopausal support, this supplement offers a diverse mix of multiple strains. The variety in the formulation might make it a supportive option for maintaining overall wellness following menopause,” says Rifkin.

    “Postmenopausal women are particularly susceptible to experiencing bone health concerns like osteoporosis. This probiotic supplement contains strains of lactobacillus that research suggests may help support bone health, which can be particularly beneficial to women in this life stage,” agrees Manaker.

    It also contains a prebiotic fiber blend from organic potato starch and organic acacia fiber. Potato starch can support gut health and may even prevent overeating, while acacia fiber has been seen to promote the growth of beneficial bacteria and reduce constipation, especially in those with IBS.

    This product is also third-party certified by NSF, one of the most reputable third-party testing bodies. Note: The proprietary blend means we don’t know the CFUs of each strain.

    Best for Pregnancy

    Culturelle Women’s Wellness Probiotic Chewables

    $22.07 at Amazon
    $23.79Now 7% Off

    Pros

    • Research-backed strains for pregnancy and infant health
    • Convenient chewable form
    • Special lining to preserve freshness
    • Third-party tested

    Cons

    • Contains proprietary blend
    • May cause stomach discomfort
    • Contains sugar alcohols
    • CFU count: 12 billion CFU
    • Probiotic strains: Lactobacillus rhamnosus, Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus jenseii
    • Other ingredients: N/A
    • Serving size: 1 chewable tablet
    • Form: Tablet
    • Third-party tested: Yes
    Culturelle Women’s Wellness Probiotic is one of the best probiotics for pregnancy and breastfeeding because of its research-backed strains for women and infant health and its stringent safety testing. This product contains 12 billion CFUs and five different lactobacillus strains, beneficial for vaginal and reproductive health. One such strain is Lactobacillus rhamnosus GG, which research has linked to reduced eczema risk in infants.

    “During pregnancy, taking Lactobacillus rhamnosus GR-1 in the third trimester can significantly reduce group B streptococcus (GBS) colonization. This common bacteria, which can be transmitted to the fetus during delivery, poses a serious infection risk to newborns,” says Elena Usdenski, RD, a certified fertility and prenatal dietitian in Markdale, Ontario.

    These Culturelle chewables are also packaged with a special desiccant lining to absorb moisture and protect the viability of the live bacteria present. We also love that they’re chewable, not capsules, which can be easier to swallow if you’re experiencing morning sickness. It’s important to note, however, that this product does contain mannitol and xylitol, sugar alcohols that may cause gas or bloating in a small percentage of people.

    Xylitol may also promote blood clotting and increase the risk of heart attack or stroke, according to new research published in the European Heart Journal, so this is something to discuss with your doctor if you have medical conditions that put you at increased cardiovascular risk.

    “Always look for strains that are well-studied for their safety and beneficial effects on maternal and infant health. Probiotics are generally thought to be safe to use during pregnancy according to research, with only minor side effects like stomach issues and no major health problems for mothers or babies,” says Alyssa Simpson, RDN, the owner of Nutrition Resolution in Phoenix, Arizona.

    Our experts agree that when choosing probiotics for pregnancy and breastfeeding (and at all times), always speak to your doctor first.

    Best for Weight Loss

    Physician's Choice Thin 30 Probiotic

    $29.97 at Amazon

    Pros

    • Contains weight loss blend
    • Includes prebiotics
    • Digestive enzyme blend
    • Third-party tested

    Cons

    • Includes some processed ingredients like sunflower oil
    • Prebiotics may cause gas
    • CFU count: 15 billion
    • Probiotic strains: Six diverse lactobacillus and bifidobacterium strains
    • Other ingredients: Prebiotic blend, digestive enzyme blend, weight loss blend (apple cider vinegar, cayenne pepper, green tea)
    • Serving size: 1 capsule
    • Form: Capsules
    • Third-party tested: Yes

    If weight management is your goal, Physician’s Choice Thin 30 is one of the best probiotics for weight loss. This probiotic contains 15 billion CFUs and three core components to support weight loss: a probiotic blend, a prebiotic blend, and a weight-management blend. The probiotic blend contains six lactobacillus and bifidobacterium strains with the potential to support weight loss alongside a healthy diet and exercise regimen.

    “A 2021 systematic review analyzed 27 studies looking at probiotics and weight loss, and 23 of them showed that probiotics had a positive effect on weight loss, with the most effective strains being lactobacillus and bifidobacterium, both found in Physician's Choice,” says Lainey Younkin, RD, the owner of Lainey Younkin Nutrition in Boston.

    Bifidobacterium lactis, which is in Physician's Choice Thin 30 Probiotic, was shown to reduce visceral fat in one study,” adds Younkin.

    Visceral fat is a type of fat in the belly area that’s associated with more health risk factors.

    In addition to several research-backed probiotic strains, Younkin notes Physician's Choice contains prebiotics from chicory root and Jerusalem artichoke root. While these aren’t always easy to get naturally in your diet, they help the probiotic bacteria flourish and produce other compounds that may help regulate appetite and influence fat metabolism.

    The weight-management blend contains added metabolism-supporting ingredients such as green tea extract, organic apple cider vinegar, and Capsimax cayenne pepper extract. When combined with a healthy lifestyle program, green tea, and cayenne pepper extract may suppress appetite and provide a modest weight loss boost in women.

    Best for Mental Health and Mood

    Zenbiome Dual

    Pros

    • Clinically studied strains for mental health
    • Dual-action for digestive and mental health support
    • Third-party tested

    Cons

    • Priciest on our list
    • Contains proprietary blend
    • CFU count: 10 billion
    • Probiotic strains: Bifidobacterium longum blend
    • Other ingredients: N/A
    • Serving size: 2 capsules
    • Form: Capsules
    • Third-party tested: Yes
    Emerging research is demonstrating a link between our gut health and mental health, and research into the role of probiotics for mood and mental health is developing as well.

     Zenbiome Dual is a solid choice to support mental health alongside a healthy lifestyle and a regular stress management routine. Zenbiome's dual-action probiotic is designed to promote digestive health and mood at the same time. Probiotics intended to improve mood are called psychobiotics.
    This supplement contains a probiotic blend of two bifidobacterium strains that research suggests can support mental health. “Zenbiome Dual supports digestion and mood with Bifidobacterium longum strains,” says Amy Archer, RDN, the owner of WellnessRD in Campbell, California. She notes that these strains may reinforce the gut-brain axis, affecting mood regulation and daily social stress, according to a study.

     “There’s an exciting area of new research, with human and animal studies showing that psychobiotics change the gut microbiome, improve cognition, and reduce anxiety and stress levels. When consumed in adequate amounts, these probiotics improve gut diversity and may produce a mental health benefit. It provides these benefits by targeting the gut-brain axis, the nerve connection between the brain and gut,” says Archer.

    While we know there is a clear connection between the gut and the brain, more robust research is needed to confirm the connection between probiotics and mental health. Note: The proprietary blend means we don’t know the CFUs of each strain.

    Ritual Synbiotic+ is a 3-in-1 subscription-based supplement called a “synbiotic,” featuring a combination of probiotics, prebiotics, and postbiotics designed to support gut health. Postbiotics are byproducts from food digestion that may provide benefits on their own, such as supporting immunity and gut health.

    Using a subscription supplement service like Ritual can help you be consistent when it comes to taking your probiotics. The website’s sign-up process is super simple and straightforward; you can sign up for a monthly subscription of probiotics, plus other supplements in a bundle that fits your health goals. "I like Ritual Synbiotic+ because it provides an impressive trifecta of digestive support, including pro-, pre-, and postbiotics. Postbiotics, the byproducts of probiotic activity, are gaining attention for their role in reinforcing your gut barrier and supporting your immune system. Research suggests that this combination of pro-, pre-, and postbiotics may help restore balance within your gut microbiome," says Hirsch.

    Their synbiotic contains two well-studied probiotic strains, Lactobacillus rhamnosus (L. rhamnosus) and Bifidobacterium animalis ssp. Lactis (BB-12®). L. rhamnosus is one of the first patented probiotic strains and has been studied for its effectiveness for over 30 years, including its role in digestive health and immunity.

     Bifidobacterium animalis ssp. Lactis has also been studied for its multiple benefits, including its role in reducing abdominal fat.

    Ritual is third-party tested and also employs a scientific advisory board composed of medical doctors, registered dietitians, and scientists who perform ongoing research to further ensure the optimal safety, quality, and effectiveness of their products. Ritual as a brand values transparency and their synbiotic is “Made Traceable,” which means they outwardly share where their ingredients come from on a Traceable Ingredients page.

    How We Tested the Best Probiotic Supplements

    We consulted with 10 qualified nutrition experts, including registered dietitians, when selecting the best probiotics for women. These experts are credentialed subject matter experts who do not have any financial conflicts of interest. I’m a registered dietitian with expertise working with pregnant and breastfeeding women in her practice, so she understands this population's unique needs.

    You can trust our reviews as we engage in ongoing independent research, which includes examining peer-reviewed studies for data that supports the ingredients we recommend. In addition, we often use and test the products ourselves or recommend them to clients and therefore provide real-world experience. We independently chose the best probiotics for women based on brand trustworthiness, third-party testing, the presence of clinically studied strains for various health reasons, and more. We also hand-picked products with positive customer reviews and that are transparent in backing up their health claims. Here are the 10 nutrition experts we consulted for additional expertise:

    What to Look for When Buying a Probiotic Supplement

    When shopping for the best probiotics for women, here are some key features to look for to make the most out of them.

    Intended use: Look for a probiotic with the types of strains linked to the health benefits you’re trying to achieve. “For example, some probiotics may help reduce urinary tract infections, while others are best for supporting symptoms of IBS,” adds Beale. You can use this article as a guide and starting point before discussing it with your doctor.

    Well-researched strains: Certain probiotic strains have been more heavily researched than others to confirm their benefits and safety. “I do like seeing the more heavily researched strains including Bifidobacterium bifidum, Lactobacillus rhamnosus GG and Lactobacillus acidophilus,” says Christa Brown, RDN, who is in private practice in Woodbridge, New Jersey.

    CFU count: CFU, or colony-forming units, indicates the quantity of bacteria per dose. While there is no universal CFU count recommended, a minimum of 1 billion CFU is the potency seen to show benefits in research studies, and more may be recommended for certain uses according to your doctor’s recommendations.

    Third-party testing: Look to see if the probiotic has undergone third-party testing or has been independently tested to ensure quality, potency, and safety. Other certifications that attest to quality are CGMP certification for Good Manufacturing Practices or Clean Label certifications.

    Potential allergens: Check for additional ingredients like lactose, gluten, or soy if you have any sensitivities, as these can affect tolerability.

    Shelf stability: Some probiotics are formulated to be shelf-stable, meaning they don’t require refrigeration. This can help maintain potency, especially if you travel frequently or store supplements in various environments.

    FAQs

    Who should take probiotics?
    Anyone who wants to support their overall digestion, immunity, and well-being may benefit from probiotics, but research is ongoing. Those with weakened immune systems may be at a heightened risk of infection from the bacteria in the supplement and are advised against taking them. In these cases, probiotic-rich fermented foods such as yogurt and kefir are preferred and safer, but it's best to check with your doctor first if you’re severely immunocompromised.
    Some people may experience gas, bloating, diarrhea, or stomach upset when starting probiotic supplements. For many people, these side effects typically resolve within a few weeks once the body adjusts to the probiotic. Start with a smaller dose and slowly increase it to allow your body to adjust. If side effects last longer than a few weeks, stop taking it and consult with your medical provider for guidance.
    This depends on the manufacturer and the specific probiotic strain. Certain products should be taken on an empty stomach, while others should be taken around a meal. Always check manufacturer instructions for how to take it.
    No, one probiotic supplement may work for one person and not another. We all have unique microbiomes, so a bit of trial and error and consulting with a health professional is crucial in determining what works best for your needs.
    Since probiotics are considered a dietary supplement, they don’t require U.S. Food and Drug Administration (FDA) approval to be on the market. But some probiotic companies choose to be more transparent with their ingredients and practices, or they seek third-party approval as another layer of consumer protection.
