So a few years ago, I learned about the benefits of taking a probiotic (immunity boost, digestive health, healthy skin) and so I was sold, and the search was on. Initially, I purchased another brand and for a few months I took it without complaint, but it was quite expensive (double the price of this one - for only a month’s supply). Then I randomly found this one, and I’m so happy that I did. It works extremely well, especially with my digestive issues, which is my main reason for taking it. And without running the risk of sharing TMI, let’s just say that I’m now regular, and feel less bloated. I’m certain that it’s providing other great things as well, but that is the one thing that I can say for sure that I’m receiving from it. Also, it’s extremely affordable and ... MoreSo a few years ago, I learned about the benefits of taking a probiotic (immunity boost, digestive health, healthy skin) and so I was sold, and the search was on.

I've used PB 8 for years, and I can definitely tell a difference with my IBS and other GI issues. I got my. mom on it, and she can tell a difference, too. I store it in a dry, cool place or in the frig. If you leave it in a hot car or it's expired, it won't be effective. The bacteria die, I think. I learned the hard way. I tried a lot of brands before PB 8, but this was the most effective for me and most cost-effective. I love PB 8, and I regularly recommend it to people. <3

I bought Nutrition Now, PB 8 Probiotic, 120 Vegetarian Capsules and I am very happy with the product and its effects on my digestive health. I like that the product is vegetarian, gluten-free, soy-free, and has no milk, eggs, peanuts, or tree nuts. I also appreciate that it has 14 billion active cultures and 8 strains of beneficial bacteria per serving. The product helps me with constipation, bloating, gas, indigestion, acid reflux, and other digestive issues. I also notice improvements in my energy, immunity, skin, hair, and nails. Some of the health problems that I had such as anemia, thyroid issues, inflammation, and allergies have also improved since I started taking the product.

I like this a lot! It contains 8 strains of probiotics. Originally, I purchase it for improving my digestive system health. I've been taking it for a week, to be honest, not very obvious improvement yet. Perhaps it takes longer time to alter the gut micro-environment. I may try a higher strength one.Surprisingly, it helps improves urogenital problem. Interested by this, I do more research online to see what strains are have been studied for female health benefit. The answer is Lactobacillus, which the product has plenty.
