This can lead to digestive system symptoms and increase the risk for other issues. Click here to learn more about probiotics. How quickly probiotics work will depend on several factors.
A study found that the type of probiotic strain, health condition, product formula, product quality, and dose are all important for effectiveness. In these cases, a person may notice the effects as soon as a few days later. For example, older research suggests that in combination with rehydration therapy, probiotic treatment can help reduce the duration and frequency of diarrhea by 2 days. For example, a review in Nutrients notes that people with irritable bowel syndrome IBS may notice the most benefit when taking probiotics for 8 weeks or more.
A study also shows that people who consume a high-dose probiotic drink for 12 weeks had significantly fewer upper respiratory infections than a placebo group. Continuous use of the correct probiotics may offer the best chance for symptom reduction and overall gut health. Probiotics contain a variety of microorganisms. The two most common types belong to groups called Lactobacillus and Bifidobacterium.
Some foods may naturally contain probiotics, while some companies may add them to products during the manufacturing process. Fermented and dairy foods are common sources of probiotics. These include:. Click here to learn more about probiotic foods. Click here to learn more about vegan probiotic options. People can also take probiotic supplements, which come in various levels of different strains. These are typically available in capsule form. Only one study—of 34 healthy volunteers—found a statistically significant change, and there was no indication that it provided a clinical benefit.
Despite a growing sense that probiotics do not offer anything of substance to individuals who are already healthy, researchers have documented some benefits for people with certain conditions. 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. A review by Cochrane—an independent network of experts who serve as rigorous arbiters of medical research—found that probiotics may be particularly useful in a hospital's neonatal intensive care unit. The addition of beneficial bacteria to a nutritional regimen seems to significantly reduce the likelihood of developing necrotizing enterocolitis, which is a devastating, poorly understood and often fatal gut disease that primarily afflicts preterm infants—especially the smallest and most premature among them.
Researchers think that many cases of the disease begin with an opportunistic bacterial infection in the not yet fully developed intestine of an infant.
As the illness progresses, gut tissue becomes increasingly inflamed and often starts to die, which can, in turn, rupture the intestine and flood the abdominal cavity with pathogenic microbes that proliferate to dangerous levels. Researchers estimate that 12 percent of preterm infants weighing less than 3.
Standard treatment involves a combination of antibiotics, feeding via intravenous tubes, and surgery to remove diseased and dead tissue. Probiotics probably prevent the disorder by boosting the numbers of beneficial bacteria, which may deter the harmful ones. Probiotics also seem to ameliorate irritable bowel syndrome, a chronic disease characterized by abdominal pain, bloating, and frequent diarrhea or constipation or a mix of the two.
This is known as the gut microbiome. Creating a balance between the two types of bacteria is vital for digestive health. The term probiotic has been used in the medical and supplement space for years. Probiotics are the good, live bacteria that live in the gut. These healthy bacteria help support the immune system and control inflammation.
The primary goal of probiotics is to keep a healthy balance in the body, namely the gastrointestinal tract. When a person is sick or exposed to harmful bacteria, the bacteria can offset the balance in the digestive system. This is where good bacteria, or probiotics, work to fight off the harmful bacteria and restore balance. Probiotics also support the cells that line the gut and help with vitamin absorption.
A wide variety of good and bad bacteria helps the immune system, fights depression, combats obesity, and contributes to other health benefits. It is commonly believed that probiotics need to be taken in enteric-coated capsules to protect the probiotics as they pass through the stomach before being released into the gut.
This is not necessary for probiotic strains which are resilient and able to reach the gut without damage. Learn more about common probiotic myths by reading The Survival Myth.
The good bacteria compete with pathogens for both their food sources and space in which to live, making it difficult for the undesirable bacteria to survive 9. Probiotics also produce certain acids 10 which discourage pathogen growth, whilst improving the gut environment for their own benefit and for the benefit of other types of good bacteria, which also begin to grow in numbers.
When the gut microbiome comes into balance with increased levels of beneficial bacteria and reduced levels of pathogenic bacteria, the individual may notice an improvement in their digestion and wellbeing. This is because gut pathogens produce many toxins 11 and other substances that negatively affect our health, whereas probiotic strains of bacteria produce beneficial substances, including certain vitamins and short-chain-fatty-acids that have a positive impact on our overall health.
Our gut is home to a delicate ecosystem of microbes, and many factors affect which strains flourish, and which ones may struggle. When we take a probiotic supplement, not only are we introducing new friendly bacteria to the gut, we are also facilitating the growth of our own indigenous friendly bacteria. The time it takes for probiotics to work depends on the probiotic strain being used, the composition of the gut microbiome of the individual and the symptoms the individual is experiencing. Everyone is unique with different gut microbiomes, each as unique as our fingerprints
