NOW Foods Probiotic-10 Ingredients

NOW Foods Probiotic-10 Ingredients

Bifidobacterium breve (B. breve) is a common strain of probiotic found in supplements, which helps support a healthy immune system, and promote respiratory health. In one study, the oral administration of the A1 strain of B. breve helped to prevent cognitive dysfunction, indicating its therapeutic potential for preventing cognitive impairment in patients with Alzheimer’s disease. In a separate study, the B-3 strain of B. breve showed potential for improving metabolic disorders by exhibiting an anti-obesity effect (significant fat reduction observed after 12 weeks).

Another of the main ingredients in Probiotic-10 is lactobacillus acidophilus. L. acidophilus is a type of bacteria that plays an important role in human health, through the production of an enzyme called lactase. Lactase breaks down lactose into lactic acid, which helps prevent the growth of bad bacteria. It also has numerous potential health benefits, including reducing high cholesterol levels, improving symptoms of IBS, and boosting the immune system to reduce the risk of viral infections, such as cold and flu.

One of the less common ingredients found in Probiotic-10 is streptococcus thermophilus. Although widely consumed in fermented dairy products, it’s rarely used as a probiotic product on its own. One health benefit of this probiotic strain is that it produces lactase, which helps people who are lactose intolerant to digest milk more efficiently.

Review Overview

Overall Review Rating

4.5 / 5

So, is Probiotic-10 25 Billion the best probiotic supplement for you?

The probiotic strains used are exactly the same as in the 50 billion CFU version, and you're still getting a small amount of Fructooligosaccharides (FOS) per serving, which acts as a natural alternative to sweeteners.

The official NOW Foods website has identified Probiotic-10 25 Billion as being especially beneficial for women, the over 50s, and maintaining intestinal flora balance and immune health.

Overall, in terms of delivering a wide range of probiotic strains and a high CFU in a single serving, Probiotic-10 25 Billion is one of the best probiotic supplements on the market.

It has significant advantages over single-strain probiotics, like Nature's Bounty Probiotic Acidophilus, and the company has an excellent reputation for delivering probiotics that maintain potency and stability through their shelf life, especially when refrigerated.
