The efficacy of probiotics: An evidence-based review
by Ben Assaf
Probiotics have been a popular supplement for many years, with people taking them to improve their gut health, boost their immune system, and alleviate a variety of other health issues. But just how effective are probiotics, and what does the evidence say about their efficacy?
Probiotics are live microorganisms that are similar to the beneficial microorganisms found in the human gut. When taken as a supplement, they can help to improve the balance of bacteria in the gut, which can have a wide range of health benefits.
Improve gut health. Probiotics can help reduce inflammation in the gut, alleviating symptoms of conditions such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). They can also help to improve the absorption of nutrients, which can lead to better overall health.
Boost the immune system. Studies have shown that probiotics can help reduce the incidence of respiratory infections and the duration and severity of such infections. This is thought to be due to how probiotics help modulate the immune system, leading to better overall function.
Potential to alleviate other health issues. Clinical trials have shown probiotics can be successful in reducing symptoms of conditions such as allergies, eczema, and mental health issues. While the evidence for these benefits is not as strong as it is for gut health and immune function, there is still some promising research in this area.
It’s important to note that not all probiotics are created equal, and different strains of probiotics can have different effects. Therefore, it’s crucial to choose a high-quality probiotic supplement that has been shown to be effective in scientific studies. It’s important to remember that probiotics should be used in conjunction with a healthy diet and lifestyle, and not as a replacement for these things. Additionally, it’s always a good idea to consult with your doctor before starting any new supplement regimen.
