If we consume food supplements in accordance with the recommended doses, they do not cause side effects. But, “from the moment a molecule has an action, it can have a positive as a negative effect”, warns Brigitte Karleskind, author of the “Practical guide to food supplements”.

It also happens that they concern people who are already weakened or sick, who must seek the advice of their doctor before supplementing themselves ”.
Read the label carefully
