Testimonials

Carol, SC

"I just can’t believe it and so badly hope I don’t jinx it by talking about it, lol but prebiotin is the best thing to happen to me ever!! I am 80 years young and have had IBS since about age 12. As my husband used to say, “you know where every bathroom is” and truly so. I had begun to think there was something really wrong with my gut but holy cow it’s so much better it’s unbelievable! I only wish I had found you years ago, I could have been “normal”! My gut is so much more “quiet” now. Sorry to rave on and on but just want to thank you for helping me."

Regina, CA

Frances L., NY

"A fantastic product!! How could such a tiny daily dose of something almost weightless and practically invisible produce such excellent results? Amazing! I have recommended it to many friends. And you are such humble people; not bragging about your product, not even sending out annoying flyers in the mail... a company of such high integrity as yours is very rare in this world. Thank you so much.

I've suffered from digestive problems for years but Prebiotin has truly been a life changer. Please continue your excellent, health preserving work."

Two Brains? The Answer to Treating My Depression May Be in my Gut

All of us feel sad or down sometimes. These feelings may be the result of life circumstances, from a lost job to the death of a close family member or friend. Other times we are not clear why we feel sad—we may have a genetic vulnerability to depression, faulty mood regulation by the brain, or even a chemical reaction to specific medications. For some of us, the feelings of sadness lift quickly. Sometimes we have a “perfect storm” of several factors coming together to lead us into a major depression.
