Which Probiotics Can Survive Stomach Acid

What Bacteria That Can Survive In A Very Acidic Environment

Do Probiotics Really Need to Survive the Stomach Acid?
  • Human stomachs contain Helicobacter pylori, one of the most common bacteria responsible for 90% 95% of stomach ulcers
  • It is a type of bacterial infection caused by Thiobacillus acidophilus
  • Acetobacter aceti. This form of bacteria causes food poisoning.
  • A solitary oligistic fly of the pleodial wing of a corboxydovoran.
  • What Types Of Probiotics Help Acid Reflux

    Probiotics that contain strains from lactobacilli and bifidobacteria may be helpful with acid reflux and associated issues.

    Probiotics of high quality can offer various benefits to the microbiome, including relief from GERD, aiding in digestion, optimizing bowel movements, supporting immune function, and weight loss. Probiotics may also be helpful with GI symptoms like irritable bowel syndrome , diarrhea, and small intestinal bacterial overgrowth .

    Probiotic supplements are not regulated by the FDA in the same way that pharmaceutical drugs are. This means there is not a standard of quality that probiotics are required to meet during manufacture. When seeking relief from gastrointestinal abnormalities such as GERD, it is recommended to purchase probiotics that research has proven effective. Omni-biotic probiotics have been researched and have been shown to improve gastrointestinal symptoms by the user.

    In studies, specific probiotic strains from the genus Lactobacilli have decreased gastric acid production in an animal model and increased pepsinogen . PGI may help improve digestion and decrease gastric residence time. Bifidobacterium adhered to stomach cells and prompted mucin production, improving the gastric barrier to acidic stomach content.

    These bacteria strains may be more effective than other stains due to limited evidence between probiotic strains. The limited evidence is related to small quantities of available trials.

    Which Probiotics Should You Add To Your Diet

    Probiotics are commonly found in food. They are also available in dietary supplements.

    Food. Many foods have good bacteria. However, these bacteria dont always survive strong stomach acids and may not be able to add to gut health. Other foods have probiotic strains that can survive the digestion process and successfully reach the gut.

    Whether a food truly has beneficial probiotics depends on three things: the levels of good bacteria contained when eaten, whether the good bacteria can survive passage through the stomach, and whether those strains of bacteria are able to support your health.

    These are a few foods that provide a good source of probiotics:

    • dried beans and other legumes
    • garlic
    • green bananas
    • wheat

    Dietary supplements. Probiotics are also available as capsules, powders, liquids, and more. The wide variety of available products can make it difficult to determine which ones offer health benefits based on science.

    Some of the best probiotic strains for health include:

    Lactobacillus acidophilus. Lactobacillus acidophilus balances potentially harmful bacteria that can otherwise grow in your gut due to illness or antibiotics.

    Lactobacillus fermentum. Lactobacillus fermentum strengthens your immune system and prevents gastrointestinal and upper respiratory infections.


    Lactobacillus plantarum. Lactobacillus plantarum stimulates your digestive system, fights off disease-causing bacteria, and helps your body produce vitamins.

    Which Acid Reflux Symptoms Could They Ease

    A 2020 systematic review investigated the effects of probiotics on GERD. The authors looked at 13 studies of varying quality, 11 of which found that probiotics had some benefit for acid reflux. The specific benefits are below:

    • One study noted improvements in reflux or heartburn.
    • Five studies noted improvements in shortness of breath.
    • Three studies noted a reduction in regurgitation.
    • Nine studies noted improvements in other gastrointestinal symptoms, such as:

    2019 study investigated the effect of probiotic supplements in adults taking the PPI esomeprazole for reflux esophagitis. Over 8 weeks, one group of participants took esomeprazole with a probiotic, while a second group took esomeprazole with a placebo.

    At 12 weeks, the researchers assessed the participants with cured esophagitis. The group that had received the probiotic had lower rates of SIBO and decreased diarrhea.

    A 2018 study looked at the effects of probiotics on SIBO in children with GERD. The 12-week study included 128 participants with GERD and 120 without it. The researchers divided the children with GERD into two groups. One received a PPI with probiotics, and the other received the same PPI with a placebo.

    At the end of the trial, the children who took probiotics had lower rates of SIBO, compared with those who took a placebo. These lower rates were similar to those of children without GERD.

    and Enterococcus faecium. Any of these may help with acid reflux.

    What Are Probiotics And Prebiotics

    Probiotics are live microorganisms that deliver health benefits for the consumer. Beneficial microorganisms have been consumed by humans to improve health for thousands of years, mainly in the form of fermented foods.

    In the early 1900s Elie Metchnikoff, a Nobel Laureate in Medicine, first introduced the concept of probiotics as it is known today. They are mostly bacteria, but some fungi are also known to have health benefits and are found in foods like yoghurt, kefir , sauerkraut and tempeh.

    Lactobacilli and bifidobacteria are the most widely used probiotic bacteria in the food and nutraceutical industries. These species are also referred to as lactic acid bacteria or acidophilus strains. They are generally-recognised-as-safe , which means consumption of GRAS products have no health risks to people.

    Food products also contain prebiotic substances, which are basically undigestible plant fibres that feed the probiotics and native gut microbiota the bacteria that normally live in the intestines. Fibre-rich foods including vegetables, fruits and wholegrain cereals contain prebiotic substances.

    What Is A Good Probiotic

    Several factors go into making a good probiotic. First of all, try to look past the big numbers that are used in marketing. Youll see adverts for probiotics that have 50 billion, 100 billion, even 200 billion CFUs! The harsh reality is that these numbers are usually irrelevant. Probiotics with high CFU counts often deliver only a few of those bacteria past your stomach acid. Time-release tablets, for example using patented technologies like BIO-tract, can deliver 15 times more bacteria to the gut than an equivalent probiotic in a vegetable capsule.

    For example, my preferred Balance ONE Probiotic contains 15 billion CFUs of bacteria. It uses time-release tablets, and each one of those tablets delivers the same amount of bacteria to your gut as a 225 billion CFU probiotic in a vegetable capsule.

    Second, look for the strains that the probiotic contains. A good probiotic for digestive health and immune support should contain at least 5 strains, and preferably 10. All of those strains have different benefits and characteristics. The more you take, the more benefits youll enjoy.

    Lastly, watch out for unnecessary sweeteners or flavors. No one needs their probiotics to taste like candy! Many probiotics, and especially probiotic gummies, contain a range of sweeteners and other ingredients that can actually impair your gut health.

    The Ultimate Proof Of Survival: Human Clinical Trials

    But ultimately, the most conclusive proof that any probiotic reaches the gut alive is how it makes people feel when they are taking it.

    Choosing a product that has credible scientific research behind it showing that it positively impacts human health is the best way to know that you are spending your money wisely. By choosing a probiotic that has been used in studies on human subjects, and has demonstrated a positive influence on the health of the test subjects is perhaps the only reliable way to select the best probiotic for you. Learn more by reading the article: Research – is it all equal?.

    Different human trials look at different areas of health, for example a study may look for benefits to gut health from taking a certain probiotic strain, or it may look for improvements in vaginal health, or even in cholesterol levels. Be sure to look for studies that are relevant to your particular set of health symptoms, so that you can select the best probiotic product for yourself. Enjoying health benefits from taking a probiotic is the ultimate confirmation that the probiotic supplement you are taking are surviving the journey through your stomach and colonising effectively.

    In order to evaluate the survival of lactobacilli in acidic conditions, we compared the survival of five Lactobacillus strains in simulated gastric juice, pH 2.0, for 90 min. L. rhamnosus GG had the highest survival rate over the 90 min of exposure to simulated gastric juice , while the poorest survivor was Lactobacillus paracasei NFBC 338, whose concentration declined to undetectable levels after only 30 min of exposure .1). While L. rhamnosus GG exhibited good survival in this system, a second L. rhamnosus strain, strain E800, was a poor survivor the concentration of this strain declined by 6.62 log10 CFU ml1 over 90 min. Overall, the data showed that the survival rates of Lactobacillus species differ and that differences are also apparent at the strain level.

    Benefits Of Probiotics For Older Adults

    In addition to balancing good and bad bacteria, probiotics offer a number of benefits to older adults.

    • They help reduce the frequency and duration of diarrhea.
    • Some strains can help improve heart health.
    • They can help relieve lactose intolerance the inability to digest sugar in dairy products.
    • They can help relieve various food and skin allergies.
    • They help reduce inflammation in the vagina due to an overgrowth of bacteria.
    • They can improve unpleasant odor in exhaled breath.

    Can You Take Prebiotics And Probiotics Together

    As probiotics grow in use, prebiotics is beginning to get attention as well. Prebiotics come in supplement form but can also be fiber-rich foods that feed good gut bacteria. Probiotics replenish the good bacteria in the gut while prebiotics maintains the gut microbiome by feeding the good bacteria we have in the gut. Because of this relationship between prebiotics and probiotics, it is perfectly acceptable to take them together. However, if your diet already contains healthy, fiber-rich foods then you will likely not require prebiotic supplements.

    Prebiotics contain fibers and natural sugars that encourage the growth of essential gut bacteria. They are easy to digest and keep the gut in balance. Prebiotic foods contain fiber and can include bananas, garlic, and dark leafy greens. Probiotic foods contain live cultures and include miso, some yogurts, kimchi, and sauerkraut.

    Recovery Of Viable Yogurt Strains In Trial 2

    How does Bio-Live survive stomach acid?

    Fecal colonies from day 2 samples and from day 7 samples were replica plated onto MRS and LM17. Higher numbers of colonies were investigated for day 2 in order to confirm the reliability of m-RSMA for distinguishing between enterococci, lactobacilli, and streptococci.

    The presence of L. delbrueckii subsp. bulgaricus in feces was confirmed for 6 of 10 human subjects on day 2, and the number increased by day 7, when orally administered Lactobacillus was present in 7 volunteers .1). The fecal counts for L. delbrueckii subsp. bulgaricus, as confirmed by using strain-specific molecular tools, appeared to increase in trial 1 ,2), which confirmed the improved performance of m-RSMA compared to the performance of RSMA.

    What Does The Research Say

    Probiotic doses are listed as colony forming units , which means the number of live strains in each dose.

    Different brands will have different suggested doses and uses, so its important to understand the information listed.

    Recent research found that the type of microbe strain, health condition, product formula, dose, and the quality of the product are all important for effectiveness.

    The condition or symptom youre trying to treat can affect how the probiotic works and when youll see results. If youre taking a probiotic for general gut or immune health, youll need to take it awhile to see results.

    On the other hand, if youre taking a probiotic for relief from diarrhea, you may see faster results.

    For example, has shown that, when used in combination with rehydration therapy, treatment with probiotics can reduce the duration and frequency of infectious diarrhea in as little as 2 days.

    Another study demonstrated that people who consumed a high-dose probiotic drink containing Lactobacillus paracasei, Lactobacillus casei, and Lactobacillus fermentium for 12 weeks experienced significantly less upper respiratory infections and flu-like symptoms compared to a placebo group.

    Plus, it was shown that the probiotic drink boosted the immune system of the participants by increasing levels of antibodies including sIgA in the gut after 12 weeks.

    Depending on what youre taking probiotics for, you may see symptom improvements anywhere between a few days to a few months.
