What Is The Optimal Dosage Of Probiotics?

”Reading < 1

What is the optimal dosage of probiotics?? The optimal dosage of probiotics can vary depending on the specific strain of probiotics and the individual’s health condition. However, generally speaking, a daily dosage of 1-10 billion colony-forming units (CFUs) is considered safe for healthy adults.

According to a study published in the Journal of Clinical Gastroenterology in 2002, a daily dosage of 10 billion CFUs of the probiotic strain Lactobacillus acidophilus improved symptoms of irritable bowel syndrome (IBS) in adults. Another study published in the World Journal of Gastroenterology in 2014 found that a daily dosage of 5 billion CFUs of the probiotic strain Lactobacillus rhamnosus improved symptoms of anxiety and depression in adults.

It’s important to note that different probiotic strains have other effects and optimal dosages, and it’s best to consult with a healthcare professional to determine the correct dosage and probiotic strain that best fits your needs. Additionally, it’s important to purchase probiotics from reputable companies to ensure the product’s safety and purity.
