Real-life impact
Biotic⁺
We ran an in vivo study to measure the impact of Biotic⁺. This eight-week, placebo-controlled trial studied the well-being, microbiomes, and gut functions of 33 healthy participants.
The results
73% felt better mood*
68% improved perceived health*
92% maintained or increased microbial diversity*
Biotic⁺
We conducted an in vitro study with our independent lab partners ProDigest, who tested the efficacy of Biotic⁺ using their SHIME® (Simulator of Human Intestinal Microbial Ecosystem) model.
The results
33.9bn CFUs reached colon alive
↑ butyrate production
↑ acetate production
↑ propionate production
