With Prebiotin, you can easily add prebiotic fiber to your diet without worrying about eating huge amounts of troublesome foods or hunting down hard-to-find ingredients. You also won’t have to worry about loading up on high-calorie foods that can negatively affect any effort to lose weight. Combining Prebiotin prebiotic fiber with a diet enriched with probiotic foods can only help your effort to positively influence the bacterial balance in your lower gut.
Probiotics, like all strategies for helping promote your health, might not work for everyone. People have different diets, the microbes colonizing their gut are specific to each of us and everyone’s physiology is unique. Research often shows that some people respond to a specific probiotic strain and others do not. So if you feel a probiotic is something you’d like to use, one strategy is to try a product for about a month. If you don’t see a benefit, then perhaps it’s not the right one for you.
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.
Some yogurts contain the aforementioned bacteria; however, because they are sensitive to oxygen, light, and dramatic temperature changes, make sure to look for yogurts with “live and active cultures.” Many commercial yogurts are heat-treated or pasteurized, resulting in the loss of these valuable cultures. Learn more about the smart way to shop for probiotics.
Further complicating things is that the mix of bacteria in people’s guts varies widely — in fact, it’s probably unique to you, like a fingerprint. What’s more, your microbiome can change based on your diet or lifestyle, or due to illness, so what might work for one person with a certain condition or symptom might not won’t work for another, Dr. Rawls says.
Pure Therapeutics Power Probiotic 100B offers 100 billion CFUs of 4 powerful probiotic strains, including science darling, the HN019 strain of Bifidobacterium lactis. Since environmental factors, including moisture, oxygen and heat, can degrade the stability of your probiotics, Pure Therapeutics 100B is delivered in nitrogen-purged aluminum blister pacts, which ensure viability until the probiotic hits your system. No refrigeration is required.
Some studies suggest that certain probiotic strains may also help in mild to moderate ulcerative colitis and possibly for bloating and gas in irritable bowel syndrome (IBS). Probiotic supplements, on the whole, “improve global symptoms, bloating, and flatulence in IBS,” by modifying the gut microbiome, according to a 2014 monograph from the American College of Gastroenterology. As IBS researchers said in a paper in Gastroenterology & Hepatology in 2015, “The concept of manipulating the microbiome is one of the most promising new ways in which to treat patients with IBS, but there is still much to learn.”
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.
Unless you know that your body is lacking in a particular type of probiotic, you should just look for broad-spectrum probiotics that contain a mix of different strains of bacteria, Warren says: "We have billions of bacteria in our gut, so by taking a supplement with a range of different strains, you will ensure you are not overdoing or missing one type." Keatley also stresses the importance of finding a supplement with a diversity of bacteria strains to keep overgrowth of any one strain in check. "Providing too much of an advantage to one strain of probiotic may push out another strain we didn't know was important until it's too late," she points out.
Probiotics' side effects, if they occur, tend to be mild and digestive (such as gas or bloating). More serious effects have been seen in some people. Probiotics might theoretically cause infections that need to be treated with antibiotics, especially in people with underlying health conditions. They could also cause unhealthy metabolic activities, too much stimulation of the immune system, or gene transfer (insertion of genetic material into a cell). 

Survival past stomach acids - probiotic powder in capsule form is ill prepared when it comes to protecting the delicate bacteria from being pulverized by the harsh environment of the stomach acids. Worse, most of the organisms tend to die off before they reach their intended destination due to moisture that gets trapped between the capsule shell and the powder.
Lactobacillus predominantly live in your small bowel (the portion of your gut that follows the stomach). Probiotics containing Lactobacillus sp. help to repopulate the small intestine with friendly organisms that aid in supporting digestion and immune function. The most beneficial are L. acidophilus, L. plantarum, and L. paracasei. One study found Lactobacillus acidophilus could reduce gut inflammation. L. rhamnosus helps increase GABA expression (an inhibitory neurotransmitter that helps you feel relaxed) in the brain, resulting in lower anxiety and depression-related behavior. Another found that a combination of Lactobacillus and Bifidobacteria (which we'll talk about next) improved symptoms of bloating in patients with functional bowel disorders, and yet another found that when people took the Lactobacillus rhamnosus GG strain, it significantly reduced the risk for antibiotic-associated diarrhea.
“There can always be differences between the species, things we don’t anticipate, which is why it’s really important we investigate thoroughly with human trials,” says Jennifer L. Pluznick, Ph.D., assistant professor of physiology at the Johns Hopkins University School of Medicine. For example, gut bacteria may bring blood pressure down in one scenario but affect metabolism and immune responses in unexpected ways. “I’m hoping that in the next couple of years, we’ll start seeing how these all these factors and findings apply to humans,” Pluznick says.
In 1907, Russian zoologist Élie Metchinkoff theorized that the gut microbiome could be modified by replacing the harmful bacteria in the digestive tract with beneficial strains instead. He also suggested that the aging process stemmed from the production of toxic substances by specific strains of bacteria in the gut. He believed that fermented foods like sour milk could help lower the pH of the intestinal tract and block the growth of bacteria.
This is one of the newer areas of probiotic research. Described as the “gut-brain axis,” researchers believe that the communication between the gut and the brain affects not just physical but also mental health and behavior. For example, a recent study found that probiotics can reduce anxiety, relieve stress and improve mental outlook. Another study found that the probiotics L. helveticus and Bifidobacterium longum reduced depression, anger, hostility and self-blame and improved problem-solving ability. Another study showed a difference in brain activity between women consuming yogurt and those consuming a placebo. More research needs to be done to confirm the effect of probiotics on mental and emotional health.
Eating more foods that are naturally rich in probiotics, like yogurt, kimchi and kefir, can help restore balance in your gut and create more “good” bacteria to fight off inflammation from “bad” bacteria. But what about food products that have probiotics infused into them? Indeed, manufacturers are banking on a new crop of gut-friendly products. From chocolates and granola bars to juices and tonics, nut butters, bottled water and even air sprays, you can’t escape the probiotic movement.
In an ideal world, women could probably get away with just “eating right.” But this would be a world in which food didn’t contain preservatives, artificial colors and flavors, or products derived from genetically modified plants. It would be a world free of toxins in the air we breathe and the water we drink. And, perhaps most importantly, it would be a world in which we were not exposed to various medications and other environmental threats that can wreak havoc on our gut bacteria and open the door for declining health.
The Bifidobacteria (Bifidus) predominantly live in your colon or large intestine. They produce the very important short-chain fatty acid butyrate, which supplies energy to your colon cells to keep them functioning optimally. But butyrate also gets absorbed by the body, regulating a variety of metabolic processes, including your sensitivity to the hormone insulin (which regulates blood sugar) and even memory formation in the brain. The most beneficial of these are B. lactis and B. longum. Research shows the benefits for Bifidobacteria include reducing inflammatory bowel disease and several cancers, especially colon cancer. Another study showed that a specific strain of Bifidobacterium lactis helped control body fat mass and reduced waist circumference and food intake.

Taking probiotics can also help keep your urinary system working properly. While you might think that yeast imbalances or urinary tract issues are primarily women's problems, both are common in men as well, especially in those whose bacterial balance is off-kilter. Taking probiotics can help address these issues by encouraging the growth of good bacteria to crowd out unwanted yeast.10
Other ingredients: Maltodextrin, hypromellose (capsule), ferment media (organic Saccharomyces cerevisiae, organic gum acacia, organic soy flour, organic molasses, lactic acid bacteria [Lactobacillus acidophilus, Bifidobacterium bifidum and Lactobacillus rhamnosus], bromelain [deactivated] and papain [deactivated]), glycerin, silicon dioxide, microcrystalline cellulose, rice extract and sunflower oil.
Lightly formulated, this probiotic from Culturelle is designed to treat occasional digestive issues like gas, bloating, and diarrhea that can occur during travel or with other changes in your routine. It contains 10 billion active cultures of just one strain of probiotic bacteria—Lactobacillus GG, which is one of the most heavily researched probiotics there is. Dairy-free, gluten-free, and sugar-free, it’s a good option when you just need a little extra support for your digestive system. It’s also safe to take every day.
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.
No matter how many superfoods you eat, your body won’t be able to benefit from them if your gut environment isn’t teeming with healthy bacteria. You see, enzymes and digestive bacteria help to break down the food you eat into molecules that make their way into your bloodstream to nourish your body. Inadequate or unbalanced microbial populations in the gut can derail this process and can even lead to malabsorption of critical nutrients. 
B. longum is one of the first types of bacteria to colonize our bodies at birth. These important microorganisms ferment sugars into lactic acid, helping to stabilize the acidity of the GI tract and inhibit growth of harmful bacteria. For a group of adults prone to constipation, taking a mix of B. longum BB536 with milk or yogurt for two weeks increased bowel movements [1].
A 2017 survey of cancer patients showed that more than 80 percent were taking some sort of dietary supplement, vitamin, mineral, or herb to treat digestive issues they were experiencing due to chemotherapy. Researchers noted that while supplements can be beneficial in some cases, they can also change the metabolism of anti-cancer drugs, or lead to life-threatening conditions like sepsis because of the patient’s compromised immune system.
Dermatologist Dendy Engelman, MD, also points out the key role probiotics play in gut health and your body's immune system. "Probiotics are live microorganisms that may be able to help prevent and treat some illnesses," explains Engelman. "Probiotics can create 'holes' in bad bacteria and kill them. Similar to the way antibiotics work in the treatment of acne and rosacea, probiotics can help fight harmful bugs from triggering inflammation. In patients with acne and rosacea, living microorganisms on the skin are recognized as foreign by the body's immune system. The immune system springs into action to counter this potential threat resulting in the inflammation, redness, or bumps common in these skin conditions."

If you want to take advantage of the benefits of probiotics and you also want to make sure the beneficial bacteria you already have is optimized to its full potential, supplement your probiotic regimen with Prebiotin. A trained microbiologist cannot tell you which probiotics are the best ones to choose, so why try to do something you are not trained to do? Eat lots of foods with prebiotics in them and take a prebiotic supplement like Prebiotin. It’s the best thing you can do to maximize the benefits of both prebiotics and probiotics on the bacteria in your gut, and your overall good gut health.
Sure, we know yogurt is good for us. It contains vitamins, minerals, protein, and bugs. Bugs? Yes, but don't panic. They're friendly. Probiotics can improve a number of health conditions, from overall immune function to gut health and more. But, what exactly are probiotics (besides, well, bugs) and what is their role in the human body? Here, we learn why supermarket shelves are popping with new probiotic products and why we should be including them in our diet.
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.
Can you take one probiotic for digestive health and a different one for vaginal health? “Unless recommended otherwise by a healthcare professional, I would recommend staggering intake within a day,” says Anthony Thomas, PhD, director of scientific affairs at Jarrow Formulas. In other words, take one probiotic with breakfast and the other at lunchtime.

Since the effects of individual bacteria strains vary, the first thing to consider when choosing a probiotic supplement is the reason you are taking it. Certain strains, for example, may help with weight loss, lower cholesterol or reduce allergy symptoms, while others have been shown to help with digestive issues, such as diarrhea from antibiotics and irritable bowel syndrome. The uses and evidence for various strains are summarized in a reference table in the Probiotic Supplements Review (be aware that certain strains should be avoided by people with milk allergies or people taking certain medications).


Because poor gut health is related to autoimmune responses like those found in rheumatoid arthritis (RA), probiotics have been a proposed treatment option for the condition. Only a few studies have been conducted in humans, and only one testing L. casei 01, a particular probiotic strain, was able to find a decrease in RA inflammation and progression of the disease.
Although many manufacturers will make claims regarding the benefit of probiotics for all sorts of disorders, there is not always research to back up those claims. It can be difficult to conduct quality research on probiotics due to the wide variety of strains available. And many studies show mixed results. However, given that, there is some research support for the use of probiotics for the following health conditions:
Antibiotics are simply overprescribed. Most of the time, rest and immune support are enough to resolve infections for which doctors often prescribe antibiotics. Antibiotic overuse is leading to more antibiotic-resistant bugs that are difficult to treat and can claim lives. Each time you take antibiotics, you also alter your gut flora. If you don’t eat the right foods, including cultured or fermented foods, you’ll inevitably suffer from dysbiosis—an imbalance between favorable and unfavorable microorganisms in the gut.

It’s important to note that there are different types of strains of probiotics. The probiotics benefits of one probiotic strain may be completely different from the health benefits seen from another probiotic. If you want to use probiotics to address a specific health concern, it’s vital to select the right probiotic for the right condition — or you can consume a wide range of probiotics in your food to be covered.
What's more, people who have serious heart issues commonly have S. mutans in their heart valves—this is an undesirable type of bacteria that’s actually more often found in the mouth. If your oral microbiome is in balance, S. mutans are normally kept in control by more beneficial species, but if things get out of balance, they can reproduce and make their way into your bloodstream via openings in your gums, compromising your cardiovascular function.3
Self-dosing with bacteria isn't as outlandish as it might seem. An estimated 100 trillion microorganisms representing more than 500 different species inhabit every normal, healthy bowel. These microorganisms (or microflora) generally don't make us sick; most are helpful. Gut-dwelling bacteria keep pathogens (harmful microorganisms) in check, aid digestion and nutrient absorption, and contribute to immune function.
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.
When it comes to probiotics, it appears that 10 billion live "friendly" bacteria is the magic dose, Dr. Novey says. That number may sound like a lot, but that’s about how many are in an eight-ounce carton of yogurt. (Check the expiration date, Novey notes: The further away the date, the more live bacteria the yogurt is likely to contain.) The probiotic supplements you buy in the health food store probably contain about 10 billion live bacteria per capsule as well. However, according to Novey it’s better to get your daily intake of probiotics from yogurt and other fermented foods than from pills or capsules. For example, yogurt also provides calcium, a much-needed nutrient. “Capsules are better when you need to recover your colon from having taken antibiotics,” he says.
"We found an increase in the number of good bacteria" among the babies given the probiotic says Underwood. By measuring samples of the babies' poop, they documented a 79 percent increase in levels of bifidobacteria, a type of bacteria that is thought to be protective. At the same time, Underwood and his team also measured a decrease in potentially harmful bacteria such as clostridium in the babies' guts.
This is one of the newer areas of probiotic research. Described as the “gut-brain axis,” researchers believe that the communication between the gut and the brain affects not just physical but also mental health and behavior. For example, a recent study found that probiotics can reduce anxiety, relieve stress and improve mental outlook.

These are live microorganisms that will not provide the promised benefits if they don't remain alive. The manufacturer and consumer must pay close attention to the conditions of storage at which the particular microorganism will survive and the end of their shelf life. The potency will indicate the number of viable bacteria per dose, and the purity has to do with presence of contaminating or ineffective bacteria.

Probiotics have received renewed attention in the 21st century from product manufacturers, research studies, and consumers. The history of probiotics can be traced to the first use of cheese and fermented products, that were well known to the Greeks and Romans who recommended their consumption.[52] The fermentation of dairy foods represents one of the oldest techniques for food preservation.[53]

Antibiotics are a common treatment for children, with 11% to 40% of antibiotic-treated children developing diarrhea.[13] Antibiotic-associated diarrhea (AAD) results from an imbalance in the colonic microbiota caused by antibiotic therapy.[13] These microbial community alterations result in changes in carbohydrate metabolism, with decreased short-chain fatty acid absorption and osmotic diarrhea as a result. A 2015 Cochrane review concluded that a protective effect of some probiotics existed for AAD in children.[13] In adults, some probiotics showed a beneficial role in reducing the occurrence of AAD and treating Clostridium difficile disease.[14]

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.
Like kefir, kombucha is a fermented drink that may improve the function of the immune system and boost energy levels and detoxification. Beneficial bacteria in kombucha may improve antioxidant activity in the body as well. Kombucha tea comes in black and green varieties. Kombucha tea is made using a SCOBY, or a symbiotic colony of bacteria and yeast, that is necessary for the fermentation process. Saccharomyces boulardii is a probiotic yeast strain that is found in kombucha.
Though most probiotics are formulated for both men and women, Garden of Life’s Raw Probiotics for Women is manufactured with women in mind.

Having a healthy gut flora means an abundance for your health, digestion, well-being, and even beauty! As we saw last week, there’s ongoing communication between your GI and your brain, known as the gut brain axis. This means a healthy gut can benefit the regularity of your digestion as well as cognitive function like mood and depression, and even the health and appearance of your skin.
Probiotics may also be of use in maintaining urogenital health. Like the intestinal tract, the vagina is a finely balanced ecosystem. The dominant Lactobacilli strains normally make it too acidic for harmful microorganisms to survive. But the system can be thrown out of balance by a number of factors, including antibiotics, spermicides, and birth control pills. Probiotic treatment that restores the balance of microflora may be helpful for such common female urogenital problems as bacterial vaginosis, yeast infection, and urinary tract infection.

Research suggests probiotics work better as a team. Even pairs are more effective than individuals. Take the strains Lactobacillus Acidophilus and Bifidobacterium Bifidum BB-12, for example. When combined, this duo-force has been shown to help treat GI-specific ailments. In fact, one survey found 75 percent of studies that compared the effect of a strain mixture with a single-strain supplement showed a mixture was more effective at improving irritable bowel symptoms, immune function, and digestive health.
