Creatine monohydrate and Thiamine drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Creatine monohydrate (creatine) and Thiamine (thiamine (vitamin b1)). Common drug interactions include malaise among females.

The phase IV clinical study analyzes what interactions people have when they take Creatine monohydrate and Thiamine. It is created by eHealthMe based on reports of 14 people who take the same drugs from the FDA, and is updated regularly.
