Some companies have been around for years, and you may know their names. Those that have made probiotics for a while likely have tested and studied them over and over. It's smarter to choose a product from them over one from a maker you don't know. Check a third-party certifier (like ConsumerLab or the USP) to see if they have tested the product and found that it’s safe and reliable. If you're in doubt, ask your doctor.
Very few women know that one of the leading causes of infertility, difficulties getting pregnant, and even painful periods stem from thyroid dysfunction. That’s why infertility specialists, obstetricians, and gynecologists alike often order thyroid testing at the first sign of trouble. Poor thyroid function is also linked to joint pain, unplanned weight-loss or obesity and heart problems and thinning skin among many other signs and symptoms.
We are clearly getting to the strain level by going beyond “Saccharomyces boulardii” and to “Saccharomyces boulardii CNCM I-745”. They did a great job by actually putting it on the label so you don’t even have to contact the company to see exactly what strain you’re getting. (P.S. this is a well-researched strain that I highly recommend, especially for preventing antibiotic-associated diarrhea.)

Within the past few years, the probiotics market has been EXPLODING. Doctors may have been prescribing them for a long time, but only recently have people started including these extraordinary supplements in their daily diets. Those who have started regularly taking probiotics have reported many improvements in their overall health. Here are some examples of the benefits thousands of daily users report:
Experts agree that this is the most important factor to consider in choosing a probiotic. "You should absolutely choose a probiotic based on what you are looking to address," says Chang. "Because strain specificity will impact outcomes, it is important to consider that one strain that works for one condition will not necessarily be effective for other conditions."
To avoid those and other problems, I strongly recommend buying a professional brand from a reputable health care professional or other vendor who stands by their products and undergoes third-party testing. Some of these professional brands have created advanced technology that preserves a probiotic supplement’s survival on the shelf and in your gut.
If your child has a history of stomach problems that medicine doesn’t seem to help, adding a probiotic to his or her diet can help. We love the OLLY Kids Happy Tummy Gummy Supplements because they offer complete probiotic support in a kid-friendly gummy form. Each gummy has a blend of prebiotic, probiotic, and peppermint to help soothe upset stomachs. They contain 500 million CFU of Bacillus coagulans. This container comes with 30 gummies (to be taken once a day) and is recommended for children 2 years and older.
"Although all of our probiotic-consuming volunteers showed probiotics in their stool, only some of them showed them in their gut, which is where they need to be," co-senior author Eran Segal, a computational biologist at the Weizmann Institute, said in the statement. "If some people resist and only some people permit them, the benefits of the standard probiotics we all take can't be as universal as we once thought."
If you’re looking for a great probiotic you can take every day to target everything from gut to skin health, the Culturelle Daily Probiotic is our top choice. Each capsule has 10 billion active cultures of 100 percent Lactobacillus GG, a probiotic that helps curb gas, bloating, and upset stomach, and works to boost your immune system. Each capsule has the probiotic equivalent of 10 cups of yogurt and is dairy-free, sugar-free, and gluten-free. This container comes with 30 pills to be taken just once a day (most recommend taking it at night, especially when you’re just starting on probiotics).
Probiotics seem to be all the rage these days. With many purported benefits and a relatively low risk of side effects, manufacturers are taking advantage of booming business opportunities. Rather than leave your health in the hands of big business, it is important that you be as educated as possible about the best types of probiotics so you can choose what is right for you and your family.

There is one Voluntary Certification Program by which a supplement manufacturer can choose to be evaluated. ConsumerLab.com (CL) is the leading provider of independent test results and information to help consumers and health-care professionals identify the best quality health and nutrition products. Products that have passed their testing for identity, strength, purity, and disintegration can print the CL Seal of Approval on their product. This is one step toward being confident that one is getting the amount and type of probiotic promised by the manufacturer.


Flu is short for influenza, an upper respiratory viral infection. The main problem for you, and the main advantage for the survival of influenza viruses, is that there are many variations that can cause illness. Flu shots are based on virus strains that are anticipated to be widespread. Sometimes those assumptions are correct and other times they are not. This section will show you one overlooked way to fortify your body to best avoid becoming sick with the flu at all, or how to recover if you do succumb.
The other thing to remember is that these microorganisms are not all created equally. In fact, the genus, strain, and species all need to be the same for the results that found in the study to be the results that one hopes to achieve when taking it. For example, with the strain Lactobacillus rhamnosus GG, the genus is Lactobacillus, the species is rhamnosus, and the strain is GG. If any one of those is different in your supplement, you may not attain the same results.
In addition to its powerful probiotic strands, the Vitamin Bounty Women’s Pro-Daily Probiotic also features a proprietary women’s health formula. This blend includes many of the minerals and plant extracts that have been found to be the most beneficial to women’s health, making it ideal for any women that have experienced feminine health problems. Specifically, this Vitamin Bounty formula includes Ashwagandha Root Powder, Cranberry Fruit Powder and Black Cohosh Root Powder.

As with other types of supplements, scientists are still discovering the full potential of probiotics. However, when taken regularly, it is believed that they help support digestive health by helping maintain the balance of beneficial and non-beneficial bacteria in your digestive tract. Having a natural balance of good bacteria in the digestive tract can help defend against occasional digestive issues. In addition, probiotics play an important role in supporting immune health, since 70% of the body's immune system is found in the digestive tract.∗
Coming in at a close second, our runner-up as the best probiotic for women is the Culturelle Women’s Healthy Balance Probiotic. As the #1 recommended brand by pharmacists, it is easy to see why so many women are turning to Culturelle for their digestive health. Featuring the LGG culture and a laundry list of other healthy bacteria, this probiotic offers a wonderful balance between digestive and feminine health. The Culturelle Women’s Healthy Balance Probiotic is also taken in an easy, chewable tablet and can even be taken during pregnancy, making it one of the most versatile formulas we reviewed!
If your child has a history of stomach problems that medicine doesn’t seem to help, adding a probiotic to his or her diet can help. We love the OLLY Kids Happy Tummy Gummy Supplements because they offer complete probiotic support in a kid-friendly gummy form.

You experience that afternoon slump and reach for a candy bar or a sugar-laden coffee. Or maybe you go through your day, starting with a breakfast of doughnuts or sugary cereal, and then proceed to sodas for drinks, cookies to snack on, dessert after dinner, and finally to a nighttime snack of ice cream. You know that feeling; it’s that I-have-to-have-something-sweet-and- I-have-to-have-it-NOW feeling.
In October 2013, the International Scientific Association for Probiotics and Prebiotics (ISAPP) organized a meeting of clinical and scientific experts on probiotics (with specialties in gastroenterology, pediatrics, family medicine, gut microbiota, microbiology of probiotic bacteria, microbial genetics, immunology, and food science) to reexamine the concept of probiotics. They define probiotics as "live microorganisms that, when administered in adequate amounts, confer a health benefit on the host." They also differentiated between products containing probiotics and those containing live or active cultures and established the following criteria:
"People have thrown a lot of support to probiotics, even though the literature underlying our understanding of them is very controversial; we wanted to determine whether probiotics such as the ones you buy in the supermarket do colonize the gastrointestinal tract like they're supposed to, and then whether these probiotics are having any impact on the human host," says senior author Eran Elinav, an immunologist at the Weizmann Institute of Science in Israel. "Surprisingly, we saw that many healthy volunteers were actually resistant in that the probiotics couldn't colonize their GI tracts. This suggests that probiotics should not be universally given as a 'one-size-fits-all' supplement. Instead, they could be tailored to the needs of each individual."
Renew Life Ultimate Flora offers 30 billion CFUs with 10 scientifically studied strains of Bifidobacterium and Lactobacillus, which according to current scientific research, are the two most prevalent good bacteria found in a healthy gut. In other words, you might choose these if you’re seeking a careful balance designed to re-establish proper immune health and digestive equilibrium.

“Highly recommend –There are quite a few probiotics manufactured specifically for women. Some are decent while others are not so good. For me, I require one on a daily basis to maintain my feminine health. When I try a new probiotic that is made specifically for women, it makes me a bit nervous because I will end up with yeast or bladder infection if it is not effective. With AZO, I am happy to report it is a great probiotic and highly recommend it to all women! It works great.” – Vicki
Every day, we’re exposed to toxins and inflammation-causing molecules from food and the environment that negatively impact digestion through pathways, such as leaky gut, known in the medical field as intestinal hyperpermeability. In leaky gut, the tight junctions that are supposed to keep disease-contributing compounds from leaving the digestive system are disrupted, allowing a lot of things through into the bloodstream that don’t belong there.
Although some probiotics have shown promise in research studies, strong scientific evidence to support specific uses of probiotics for most health conditions is lacking. The U.S. Food and Drug Administration (FDA) has not approved any probiotics for preventing or treating any health problem. Some experts have cautioned that the rapid growth in marketing and use of probiotics may have outpaced scientific research for many of their proposed uses and benefits.
In the first study, 25 human volunteers underwent upper endoscopies and colonoscopies to sample their baseline microbiome in regions of the gut. 15 of those volunteers were then divided into two groups. The first group consumed generic probiotic strains, while the second was administered a placebo. Both groups then underwent a second round of upper endoscopies and colonoscopies to assess their internal response before being followed for another 2 months.
Garden of Life RAW Probiotics are some of the most popular out there – and for good reason. Let’s start with the basics: You’ll get 85 billion CFUs and 31 to 33 probiotic strains out of your daily, whole-food, gluten-free, soy-free probiotic, which helps support the immune system, a healthy thyroid, nutrient absorption, digestive function, and a healthy microbial balance.
An imbalance between good bacteria and pathogenic bacteria, yeasts or fungi, or a change in the bacteria species that colonize the digestive tract is called dysbiosis. It can have short and long-term effects on our body functions. These disruptions can reduce the immune system’s effectiveness, create unpleasant digestive symptoms (diarrhea, constipation, gas, etc.), be a contributor to certain chronic illnesses like obesity, and participate in producing pro-inflammatory metabolites.

The bad news about constipation is that there can be many causes, from simple causes like dehydration and lack of fiber to complicated structural causes or disease. While constipation may seem to be only a nuisance that causes uncomfortable symptoms such as abdominal bloating or pain, the truth is that constipation increases the risks of several diseases.

Yeast Infections and Bacterial Vaginosis (BV) – If you’ve ever experienced the discomfort of a yeast infection or BV, then you are probably aware that an overgrowth of bacteria causes these unfortunate episodes. While your reproductive system is supposed to foster a healthy environment for yeast, sometimes these levels can increase causing the pain and discomfort of a yeast infection or bacterial infection. By taking a probiotic that contains prebiotics and feminine health probiotics, you can treat and prevent recurrent symptoms!


As you age, your body needs different supplements and vitamins to stay healthy. Renew Life 50+ Ultimate Flora Probiotic is a smart choice for adults over 50 because it is specifically formulated with seniors in mind. It has 30 billion live cultures and 12 strains of probiotics, including Bifidobacteria, which is a probiotic that decreases in your body as you age. Seniors develop less of the “good” bacteria as they age, and Ultimate Flora has three times the average live cultures in each dose to help replenish and protect gut and immune health. This 60-day supply should be refrigerated to maintain the live cultures.
Two dangerous diseases in newborns, necrotizing enterocolitis (NEC) and neonatal sepsis, may meet their match with well-designed probiotic supplements. Both of these conditions are common in premature babies and are most dangerous in low birth weight and very low birth weight infants. Research has confirmed that when a pregnant mother takes high-quality probiotics during pregnancy, her baby is significantly less likely to develop either NEC or sepsis, particularly when the baby is breastfed after birth (and mom is still taking the supplements) and/or when probiotics are added to formula. A probiotic supplement with multiple strains seems to be the most effective in these cases.
Lebwohl says IBS isn’t just about intestinal distress. For many IBS sufferers, it’s about the way our brain receives messages about pain. He describes the human colon as “almost reptilian” in the way that it contracts and relaxes throughout the day, but says these contractions are usually happening way below our threshold of consciousness, so we don’t even notice. In people with IBS, the neurotransmitters in our gut (yes, we have them in there too) may be sending severe distress signals to the brain about benign contractions happening in digestive tract.
This high-potency (25 billion CFU) supplement blends 12 different strains in a base of inulin. The Ther-Biotic Complete capsules are vegetarian (made from hydroxypropyl methylcellulose, water) and the formula is free of common allergens, such as milk, eggs, fish, tree nuts, peanuts, wheat, gluten, and soy so it’s perfect for those with allergies. There are 60 capsules per bottle.
My husband is battling lung cancer and Sarcoma and has a lot of gut issues such as nausea and vomiting which have caused him to lose a significant amount of weight. To help with the N/V a probiotic was recommend. I’d like to try him on the BlueBiotics Ultimate Care but am concerned that by doing so it will cause him to lose even more weight which he has no extra weight to spare. What are your thoughts on this?

CFU: This is the number of "colony forming units" present in each dose, which are measured in the billions. And while more isn't always better, "you want at least 20 to 50 billion CFU," says Dr. Nazareth. Just for reference, a very high dose is 400 CFU, which most experts agree is not necessary unless your health care practitioner specifically recommends this for you. It's also important to check for the guaranteed CFU upon expiration, which should be listed clearly. "Some products only guarantee the CFU number at the time of manufacturing, therefore will be less potent by the time the product reaches your home," she says.


Even if some of the bacteria in a probiotic managed to survive and propagate in the intestine, there would likely be far too few of them to dramatically alter the overall composition of one's internal ecosystem. Whereas the human gut contains tens of trillions of bacteria, there are only between 100 million and a few hundred billion bacteria in a typical serving of yogurt or a microbe-filled pill. Last year a team of scientists at the University of Copenhagen published a review of seven randomized, placebo-controlled trials (the most scientifically rigorous types of studies researchers know how to conduct) investigating whether probiotic supplements—including biscuits, milk-based drinks and capsules—change the diversity of bacteria in fecal samples. Only one study—of 34 healthy volunteers—found a statistically significant change, and there was no indication that it provided a clinical benefit. “A probiotic is still just a drop in a bucket,” says Shira Doron, an infectious disease expert at Tufts Medical Center. “The gut always has orders of magnitude more microbes.”
Literally the best thing you can get for your body! I was having bad stomach problems and it vanished after two days of taking these regularly. Keep in mind that if you are putting junk into your body, you need good bacteria in your gut. It's crucial, roughly 80% of your immune system originates from your digestive tract. This WILL help you get your health back in order.

Another study by Elinav and his colleagues suggests that not everyone’s gut reacts the same way to probiotic pills. They studied samples of microbiomes from antibiotic users before and after they took supplements for four weeks. The good bacteria were found in the digestive tracts of some people. But in others, the bacteria were present only in stool samples, not in their digestive tracts, where they’re thought to be needed to improve health.
L. Casei also made headlines when a study found it beneficial in relieving anxiety. The randomized, double-blind, placebo-controlled pilot study found supplementation with 24 billion units of the L. Casei strain Shirota led to a rise in probiotics Lactobacillus and Bifidobacterium, as well as a significant decrease in symptoms of anxiety and depression [2].
Some digestive disease specialists are recommending probiotic supplements for disorders that frustrate conventional medicine, such as irritable bowel syndrome. Since the mid-1990s, clinical studies suggest that probiotic therapy can help treat several gastrointestinal ills, delay the development of allergies in children, and treat and prevent vaginal and urinary infections in women.
Every day, we’re exposed to toxins and inflammation-causing molecules from food and the environment that negatively impact digestion through pathways, such as leaky gut, known in the medical field as intestinal hyperpermeability. In leaky gut, the tight junctions that are supposed to keep disease-contributing compounds from leaving the digestive system are disrupted, allowing a lot of things through into the bloodstream that don’t belong there.
"In fact," she continues, "80% of immune system cells are found in the gut. In addition to the well-known GI benefits of minimizing bloat, gas, constipation, and diarrhea, probiotics aid in digestion by extracting nutrients, helping your body absorb minerals, produce vitamins, and make brain chemicals, including over 30 neurotransmitters along with mood-enhancing serotonin. A healthy person has over 100 trillion microbes, generally a five to one ratio of helpful to harmful."
"When certain types of probiotics are placed in contact with skin cells, they calm the parts of the cells that may want to react to the presence of bad bacteria that they see as a threat. These healthy signals produced by the probiotics stop the skin cells from sending 'attack' messages to the immune system that result in flares of acne or rosacea."

Myriad factors – antibiotics, diet, stress, and age, among them – affect the balance of diverse microbes present in your gut. While you can replenish your gut bacteria by eating well and incorporating natural probiotics (ex. yogurt and kefir) into a healthy diet, these processes can take weeks or months; taking a regular probiotic is an easy and effective way to ensure your gut (and immune system) stays healthy, always.
In the past five years, for example, several combined analyses of dozens of studies have concluded that probiotics may help prevent some common side effects of treatment with antibiotics. Whenever physicians prescribe these medications, they know they stand a good chance of annihilating entire communities of beneficial bacteria in the intestine, along with whatever problem-causing microbes they are trying to dispel. Normally the body just needs to grab a few bacteria from the environment to reestablish a healthy microbiome. But sometimes the emptied niches get filled up with harmful bacteria that secrete toxins, causing inflammation in the intestine and triggering diarrhea. Adding yogurt or other probiotics—especially the kinds that contain Lactobacillus—during and after a course of antibiotics seems to decrease the chances of subsequently developing these opportunistic infections.
That said, you don’t have to live in pain any longer and there are products that can help ease your symptoms without an added hassle! Whether you are struggling with yeast infections, recurrent urinary tract infections, digestive symptoms, or menopause, probiotics can dramatically increase your quality of life and ease your symptoms. After all, when you’re pain-free, nothing can stand in your way! You can also view probiotics for men here.
