In the past, probiotics have been proposed as part of a weight loss diet. However, a 2015 meta-analysis looked at available randomized, controlled trials investigating this effect and determined that the studies did not seem to support this hypothesis, as body weight and BMI were not consistently reduced. The researchers did point out the need for better designed trials, because they were not convinced the results were based on well-designed science.
Now researchers are finding evidence that the effects of bacteria in the gastrointestinal (GI) system send signals to the central nervous system, linking the gut with the brain. This could account for some known connections between GI illness and mental illness. For example, a higher-than-average number of people with irritable bowel syndrome also develop depression and anxiety. 

Bottom Line: Eating foods rich in probiotics can boost the healthy bacteria in your digestive tract, which can help you fend off indigestion and improve immunity. For individuals who either don't like probiotic-rich foods or don't get enough probiotics from foods, taking daily probiotic supplements may be beneficial. However, an overall healthy diet is still the key to maintaining optimal gut health.
Dr. Tobias responded with Deep Immune Support, a shelf-stable capsule that does not require refrigeration and employs four acid-resistant probiotic strains. One such strain: DE111, a highly effective spore-forming probiotic, which complements and balances the non-spore strains most commonly found today, and also supports the proliferation of beneficial bacteria. The patented, delayed-release capsules are made in the USA and are both kosher and vegetarian.
The high quality supplement comes in veggie capsule form, and no refrigeration is necessary. This probiotic is made in an FDA registered facility (in the US), and it meets GMP standards. It’s an all natural supplement, that’s free of lactose, soy and gluten. It also contains no artificial coloring. DNA Shift probiotic also offers prebiotic fiber for an extra healthy brain and gut.

Probiotics are living, so their viability can be affected by any number of problems with packaging and storage. We have more to learn about how best to administer probiotics. We also need to learn more about how well probiotics can remain inside your gut once they get there. Currently, it’s not believed that any dosage of probiotics will necessarily stay in your system forever. Current practice is to take daily doses of probiotics.
Many women eat yogurt or insert it into the vagina to treat recurring yeast infections, a "folk" remedy for which medical science offers limited support. Oral and vaginal administration of Lactobacilli may help in the treatment of bacterial vaginosis, although there isn't enough evidence yet to recommend it over conventional approaches. (Vaginosis must be treated because it creates a risk for pregnancy-related complications and pelvic inflammatory disease.) Probiotic treatment of urinary tract infections is under study.

Undaunted, researchers looked into whether probiotics might be beneficial in a host of disorders, even when the connection to gut health and the microbiome was tenuous. Reviews show that there is insufficient evidence to recommend their use to treat or prevent eczema, preterm labor, gestational diabetes, bacterial vaginosis, allergic diseases or urinary tract infections.
As one of the best probiotics for weight loss, there have been a slew of studies demonstrating just how powerful this strain of bacteria may be when it comes to your waistline. For instance, one study in the British Journal of Nutrition showed that taking Lactobacillus gasseri daily led to significant reductions in body weight and body fat compared to a control group, with participants losing up to 8.5 percent body fat over a 12-week period.

What is the difference between prebiotics and probiotics? Prebiotics and probiotics work together to encourage the growth of beneficial bacteria that can improve digestion and support the immune system. Both prebiotics and probiotics occur naturally in many foods. Here, learn more about the differences between them, their benefits, and how to incorporate them into the diet. Read now

A number of probiotic products are on the market, including yogurts containing probiotics, as well as supplements and skin creams, and an estimated 3.9 million Americans use such products. Some studies suggest that probiotics may help with diarrhea or symptoms of irritable bowel syndrome (IBS), but strong evidence to support their use for most health conditions is lacking, according to the National Center for Complementary and Integrative Health.

Very few studies have actually documented survival of an administered probiotic as it transits the gut, by means of fecal recovery studies. One probiotic may not necessarily be translatable to other probiotic(s): for example, different Bifidobacterium species have different tolerances to acid and growth requirements and will have different fecal recovery rates [Matto et al. 2004; Takahashi et al. 2004].
Once GI experts realized there is more to the lower gut than first assumed, the push to understand the diverse roles these bacteria play became urgent. Many mysteries still need solving, but clinical evidence increasingly indicates that people in good health should optimize lower gut bacteria. You can accomplish this by eating prebiotics to encourage the growth of your existing gut microbes, and probiotics to add to the ones that are already there.
The manipulation of the gut microbiota is complex and may cause bacteria-host interactions.[7] Though probiotics are considered safe, some have concerns about their safety in certain cases.[7][40] Some people, such as those with immunodeficiency, short bowel syndrome, central venous catheters, cardiac valve disease and premature infants, may be at higher risk for adverse events.[5] In severely ill people with inflammatory bowel disease there is a risk of the passage of viable bacteria from the gastrointestinal tract to the internal organs (bacterial translocation) as a consequence of bacteremia, which can cause adverse health consequences.[7] Rarely, consumption of probiotics by children with lowered immune system function or who are already critically ill may result in bacteremia or fungemia (i.e., bacteria or fungi in the blood), which can lead to sepsis, a potentially fatal disease.[6]
Whether a brand of probiotics works really depends on its quality and your body's own gut. Everyone has a different set of gut flora so try several to see what works for you. Using a brand of at least 40 billion CFU is best. There seems to be some debate as to whether one should use refrigerated or unrefrigerated probiotics. I went with the side that claims unrefrigerated are sturdier and less prone to die off.
It has 30 billion cultures per serving and contains 12 strains of soil-based probiotics to promote regular bowel movements and overall colon health. It also touts a unique whole-food blend with Homeostatic Soil Organisms, which basically makes up for the nutrients we miss out on due to the pesticides, herbicides, and other chemicals that typically affect food production today. Plus, this probiotic has a devoted following of fans who credit it with improvements in their digestive health.

There’s good and bad bacteria in there (fascinating fact: an estimated 100 trillion bacteria live inside your digestive tract): When the good outweighs the bad, your immune health soars; when the bad overpowers good, you get sick. You have diarrhea. Your immune system tanks. Your IBS, lactose intolerance, and other gut problems are exacerbated. It throws your entire system out of whack.
In seven people, however, these bacterial levels persisted for more than five months after the treatment ended. “We never expected they would survive more than a few weeks,” Walter says. A follow-up analysis determined that these seven people had begun the experiment with lower levels of B. longum in the first place. In other words, their gut ecosystems had a vacancy that the probiotic filled. That is exactly the kind of insight that clinicians need to create and recommend more effective probiotics. If a doctor knows that an individual with severe diarrhea has an undersized population of a particular beneficial microbe, for example, then prescribing the missing strain should increase the chance of a successful treatment.

Chronic inflammation contributes to nearly every disease imaginable, and it doesn’t do your gut any favors. Studies connect inflammation with everything from leaky gut to weight gain. Those are among the many reasons to add cold-water fish and other omega-3-rich foods to your diet. The two primary omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are important anti-inflammatory promoters in the body often deficient in the American diet. Along with these foods, take one to four 1,000-milligram softgels daily with meals to enhance their absorption.
Probiotics stick around for a while, though for how long isn’t precisely clear. You have to keep taking them to continue to reap the benefits. Further, getting a wide variety of strains into your system is beneficial. “Periodically mixing up your probiotic supplement is also a good way to ensure that you get different health-building strains in your health regime,” says Dr. Cook.

Probiotics have been used therapeutically for many centuries in different parts of the world for their contribution to longevity and digestive health. The World Health Organization has defined probiotics as ‘live organisms which when administered in adequate amounts confer a health benefit on the host’. Categories of probiotics in use today include: bacteria such as lactic-acid bacteria (LAB) and Escherichia coli strains (such as E. coli Nissle 1917), as well as yeast species including most prominently Saccharomyces boulardii among others (Table 1). Prebiotics such as lactulose, inulin, psyllium, and other oligosaccharides (found in onions, garlic, asparagus, leeks, artichoke, bananas, tomatoes, wheat, oats, soy beans, and other plants) are nondigestible food ingredients that stimulate the growth or activity of bacteria in the GI tract which are beneficial to the health of the body [Grajek et al. 2005]. Synbiotics are a combination of a prebiotic and a probiotic, such as inulin and Lactobacillus rhamnosus GG or Bifidobacter longum. Antibiotics, in contrast, are compounds that kill or inhibit the growth of bacteria.


After suffering from liquid nighttime but painless diarrhea for over a year (which I semi-controlled with one Imodium/day), I had a colonoscopy that gave a diagnosis of microcolitis. After the colonoscopy, I developed for the first time excrutiatingly painful gas pain in the LLQ. Usually this pain started during aerobic activity such as walking, but not always. Sometimes I woke up with it. CT scan revealed nothing. Will a probiotic help and if so, which would be best? There are so many it is hard to choose.

Popular probiotic foods include yogurt, kimchi, sauerkraut, and kombucha. While delicious, these foods don’t claim specific amounts of whatever microorganisms they may contain. By contrast, Probiotic All-Flora is optimally formulated with the right amounts of the right strains to deliver researched benefits. The label lists out the DNA-tested flora that make up that ideal 10 billion CFU in just one capsule daily. So probiotic supplements actually have more reliable strain benefits than probiotic foods.


Sick of fighting off cold after cold? The Align Daily Immune Support Probiotic Supplement is a great way to give your immune system a boost while protecting your gut bacteria. Align is one of the most popular probiotic brands out there and is trusted by both doctors and nutritionists. The Daily Immune Support has Bifidobacterium lactis BB-12, a probiotic strain thought to be most beneficial to your immune health. It’s a lactic acid bacteria that can also help to fight lactose intolerance. This probiotic contains five billion CFUs (generally, most adults should take at least one billion CFUs in a probiotic) and is meant to be taken once a day.
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.
The above line of probiotics is also a favorite of Engelman. "I like Nerium International's new Prolistic Pre & Probiotic Plus Vitamins ($45) because it combines prebiotics, probiotics, and vitamins," Engelman explains. "It supports overall health while targeting digestive function. It contains two types of prebiotics and two strains of probiotics to help enhance levels of beneficial microflora and balance levels of healthy bacteria in the digestive system. Additionally, it contains B vitamins, vitamin C, and vitamin D, which work to enhance the body's immune system and support natural energy production."
There are numerous types of probiotics and each has different characteristics. They may be combined with others or appear on their own in powder, tablet or liquid dietary supplements. At the moment, foods that naturally contain probiotics are not eaten regularly in the UK and supplements are becoming more popular. The most common probiotics include lactobacillus acidophilus and bifidobacterium. These differ as they are made up of different types or strains of bacteria, and are recommended for different clinical conditions. Lactobacillus acidophilus have been clinically shown to lower the incidence of antibiotic-associated diarrhoea and can also result in a shorter length of stay in hospital for some. In order to experience this benefit, a vast quantity of food containing probiotics would need to be consumed. It is therefore easier and more effective to take a recommended probiotic supplement. 
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.

The second piece of research investigated whether patients should take probiotics to help the recovery of the natural gut bacteria after treatment with antibiotics. The evidence supporting this is not entirely clear and the FDA does not officially recommend it, but there are some reputable sources which discuss their use, such as this blog from Harvard Medical School. Research has suggested that up to 60% of healthcare professionals in the U.S. recommend taking probiotics, but is this justified and could it even be harmful?


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.

The idea that bacteria are beneficial can be tough to understand. We take antibiotics to kill harmful bacterial infections and use antibacterial soaps and lotions more than ever. The wrong bacteria in the wrong place can cause problems, but the right bacteria in the right place can have benefits. This is where probiotics come in. Probiotics are live microorganisms that may be able to help prevent and treat some illnesses. Promoting a healthy digestive tract and a healthy immune system are their most widely studied benefits at this time. These are also commonly known as friendly, good, or healthy bacteria. Probiotics can be supplied through foods, beverages, and dietary supplements.
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.

“This product contains L. plantarum 299v, which has been found to be effective in treating irritable bowel syndrome (IBS), a condition millions of women suffer from,” says Ryan Whitcomb, MS, RD, CLT, a dietitian in Jersey City, NJ. “This strain helps reduce abdominal pain, bloating, the feeling of incomplete evacuation, and stool frequency.” Avoid these 10 foods that can make IBS worse.
A growing probiotics market has led to the need for stricter requirements for scientific substantiation of putative benefits conferred by microorganisms claimed to be probiotic.[3] Although there are numerous claimed benefits marketed towards using consumer probiotic products, such as reducing gastrointestinal discomfort, improving immune health, relieving constipation, or avoiding the common cold, such claims are not supported by scientific evidence,[3][10][11] and are prohibited as deceptive advertising in the United States by the Federal Trade Commission.[12]
A popular dish in Japan consisting of fermented soybeans, natto contains the extremely powerful probiotic bacillus subtilis, which has been proven to bolster your immune system, support cardiovascular health and enhance digestion of vitamin K2. Natto can also contain vitamin B12, which is usually lacking in vegan diets. It’s also one of the highest plant-based proteins.
