What The Experts Say

"The gut is responsible for regulating our energy levels and digesting our nutrients. Healthy gut bacteria can lead to increased energy and the most efficient use of the nutrients in your diet – resulting in less bloating and even weight loss. Fit contains the most studied probiotic strains for weight loss, along with strains studied to reduce bloating and constipation. "

Enjoying it

Good product, I like the philosophy of the company. Haven’t seen specific bloating/weight loss results, but otherwise happy.

Amanda Schuster
Decent as probiotic, does not deliver other promises

I have been taking this product for two months and see zero difference as compared to other probiotics. It pretty much works the same as any I've found over the counter. I work out regularly and keep a pretty healthy diet and there is zero change in "fitness" from taking this product than before.

Helped A Lot!

Was skeptical because I've tried a lot of similar products, but so far so good! Def worth it.
