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."

Our body normally has what we would call good or helpful bacteria and bad or harmful bacteria. Maintaining the correct balance between these bacteria is necessary for optimal health. Age, genetics, and diet may influence the composition of the bacteria in the body (microbiota). An imbalance is called dysbiosis, and this has possible links to diseases of the intestinal tract, including ulcerative colitis, irritable bowel syndrome, celiac disease, and Crohn's disease, as well as more systemic diseases such as obesity and type 1 and type 2 diabetes. How do you know if you need probiotics? This article will help you decide.
The original modern hypothesis of the positive role played by certain bacteria was first introduced by Russian scientist and Nobel laureate Élie Metchnikoff, who in 1907 suggested that it would be possible to modify the gut microbiota and to replace harmful microbes with useful microbes.[9] Metchnikoff, at that time a professor at the Pasteur Institute in Paris, proposed the hypothesis that the aging process results from the activity of putrefactive (proteolytic) microbes producing toxic substances in the large bowel. Proteolytic bacteria such as clostridia, which are part of the normal gut microbiota, produce toxic substances including phenols, indols, and ammonia from the digestion of proteins. According to Metchnikoff, these compounds were responsible for what he called intestinal autointoxication, which would cause the physical changes associated with old age.[54]
Some foods are made by adding bacteria — yogurt, pickles, cottage cheese, kombucha, and sauerkraut are good examples. Those foods work to provide the same probiotic benefits as supplements. However, most foods are so processed and pasteurized that it’s unlikely you’ll see the same benefits, let alone the right strains, as you would with a supplement. Regardless, it can’t hurt to get extra probiotics through your diet.
In addition to the prophylactic effect of stocking your gut with good bacteria, there are some probiotic strains that have also shown promise in treating symptoms of autoimmune disorders, including L. Paracasei and L. Acidophilus. Others, like B. Lactis, could help prevent respiratory infections. Renew Life Flora Extra Care has all three targeted bacteria strains at 30 billion CFUs per serving.
With the growing popularity of probiotics, there is a huge variety of supplements from which one can choose. The most important thing is to determine what type of probiotic microorganism you need for your condition. Do not just take the supplement that provides the most kinds of organisms. You need to do your research and be sure that there are scientific studies to support what you take. New research is emerging, so if you don't find what you need right now, keep looking. A doctor can help one decide if trying probiotics might be helpful for you and can advise you regarding the amount and type of probiotics that may be appropriate in your case.
Diarrhea is a change is the frequency and looseness of bowel movements. Symptoms associated with diarrhea are cramping, abdominal pain, and the sensation of rectal urgency. Causes of diarrhea include viral, bacterial, or parasite infection, gastroenteritis, food poisoning, and drugs. Absorbents and anti-motility medications are used to treat diarrhea.
In a separate study involving 21 healthy volunteers, also published today in Cell, the same group of researchers found that taking probiotics after treatment with broad spectrum antibiotics may actually delay the return of people's normal gut microbiome. This goes against the idea that probiotics can help "repopulate" people's gut bacteria after antibiotics wipe them out.
Remember that dietary supplements are not tested by the U.S. Food and Drug Administration like medications. And the probiotic strains in the supplements may not be specific for the condition you're looking to treat. You may want to consult with a practitioner, like a registered dietitian, who is familiar with probiotics. Always tell your physician what you are doing that may affect your health.
Unfortunately, the U.S. has no federal standards for probiotic supplements. Therefore, you run the risk of purchasing a product without any guarantee that it contains its advertised probiotic strains, that the strains are alive, or that the product is free from unhealthy ingredients. Therefore, it may be best to choose a brand-name probiotic that has research backing their effectiveness. Here are some examples:

Reviews looking at the treatment or prevention of vulvovaginal candidiasis in women, pneumonia in patients hooked up to respirators, and colds in otherwise healthy people show some positive results. But the authors note that the studies are almost all of low quality, small in size, and often funded by companies with significant conflicts of interest.
You may be hearing and seeing more about probiotics these days, but these “friendly” bacteria are nothing new. Indeed, the word probiotic is of Greek origin and means “for life.” “Almost every culture has a fermented food that contains probiotics,” says Donald Novey, MD, an integrative medicine physician with the Advocate Medical Group in Park Ridge, Ill. Products like yogurt, miso (fermented soybean paste), and some juices and soy beverages contain probiotics.
To obtain more probiotics, enjoy an assortment of fermented dairy foods including yogurt, kefir, and aged cheeses, all of which contain live cultures. The active cultures in yogurt will not only help with digestion, but also help us better absorb nutrients from our food. The FDA requires at least two strains of bacteria in all yogurts, though manufacturers can add more. Kefir is a liquid yogurt that is cultured five to eight times longer than yogurt, giving good bacteria more time to multiply. It contains as many as 12 strains of bacteria and is delicious in smoothies and overnight oats.

The discovery of the benefits of probiotics began with sour milk. Today we have many other options to get various bacteria from our foods, although it's not as simple as just adding them to the food. For there to be health benefits, the microorganism has to be able to survive the passage through the gastrointestinal tract, survive the food manufacturing process, and grow and survive during the ripening or storage period. Also, the bacteria must not negatively affect product quality and be included on the Generally Recognized as Safe (GRAS) list.
"Probiotics applied topically sit on the skin's surface and prevent the skin cells from seeing the bad bacteria and parasites that can cause this immune system response," confirms Engelman. "This is known as 'bacterial interference,' as probiotics protect the skin and interfere with the ability of bad bugs like bacteria and parasites to provoke an immune reaction.
Chlorella, a type of green algae, is thought to be one of the most nutrient-dense foods available. It contains chlorella growth factor (CGF), a complex of proteins, vitamins, and sugars that works with fiber in the GI tract to promote the growth of healthy intestinal flora. It also contains chlorophyll, a potent antioxidant that binds to toxins and helps remove them from the body. “Chlorella is known for detoxification, but I’ve found that it does wonders for promoting normal GI function,” Dr. Rawls says.
Other safety concerns relate to the unpredictability of immune modulation through change in intestinal flora in certain disease states. For example, worsening of Crohn’s disease (CD) in patients taking some probiotic formulations [Rolfe et al. 2006] or exacerbation of indomethacin-induced enteropathy in animal models by Lactobacillus GG [Kamil et al. 2007]. As rare as these complications appear to be, probiotic safety profile needs to be specifically studied, particularly in hospitalized patients. There are no formal clinical trials assessing the safety of probiotics as there are safety data on regulated medications. At this time, we can only rely on case reports, which is without a doubt suboptimal.
A closer look at the science underlying microbe-based treatments, however, shows that most of the health claims for probiotics are pure hype. The majority of studies to date have failed to reveal any benefits in individuals who are already healthy. The bacteria seem to help only those people suffering from a few specific intestinal disorders. “There is no evidence to suggest that people with normal gastrointestinal tracts can benefit from taking probiotics,” says Matthew Ciorba, a gastroenterologist at Washington University in St. Louis. “If you're not in any distress, I would not recommend them.” Emma Allen-Vercoe, a microbiologist at the University of Guelph in Ontario, agrees. For the most part, she says, “the claims that are made are enormously inflated.”
Probiotics help tip the balance back in favor of the good bacteria. In doing so, they may provide some relief if you have irritable bowel syndrome (IBS), ulcerative colitis, acute infectious diarrhea, and diarrhea associated with antibiotic use or Clostridium difficile (C.diff) infection. They also can boost your immunity, fight inflammation and potentially have beneficial effects on cholesterol.
Irritable bowel syndrome (IBS) is a multisymptom GI disorder with unclear etiology and pathogenesis. Changes in GI microflora in IBS patients have been reported by a number of investigators [Kassinen et al. 2007; Shanahan, 2007]. Recently, reports on variable prevalences of small intestinal bacterial overgrowth (SIBO) in IBS have been published [Posserud et al. 2007; Lin, 2004]. IBS symptoms such as bloating or flatulence have been attributed to possible alterations in the intestinal microflora and probiotics have been used empirically to treat these difficult symptoms [Kim et al. 2003, 2005]. Postinfectious IBS may begin after a bout of acute gastroenteritis suggesting that altered microflora or induction of an altered inflammatory or immune state in the bowel may lead to altered bowel function and IBS symptoms [Collins et al. 2009]. An increase in lymphocytes and an increase in pro-inflammatory cytokines have been described [Spiller et al. 2000].

Immunity and colds/flu.There’s a close connection between the bacteria in your colon and the immune system. Several studies, including one in 2012 in the British Journal of Nutrition, have found that certain probiotic strains boost measures of immune response—but whether this translates into any clinical benefits is uncertain. Studies have been inconsistent, for example, as to whether probiotics will actually curb colds and other upper respiratory infections. In 2014 a review in the British Journal of Nutrition, which looked at 20 clinical trials, linked probiotics to shorter duration of colds, but not necessarily reduced incidence or severity. Similarly, a 2015 Cochrane review of 12 clinical trials concluded that certain probiotics may help prevent or shorten such infections, though the quality of the studies was poor.
