What it is and how it works

Dietary supplements include a wide range of products such as vitamins, minerals, herbal products, and probiotics. These supplements are intended to provide nutrients or other substances that might support health. Each type of supplement works differently depending on its ingredients and how it interacts with the body.

For example, vitamins and minerals often serve as cofactors in various biochemical processes, helping the body function properly. Herbal products contain plant-based compounds that have been studied for their potential effects on inflammation, Immune Response, or other physiological functions. Probiotics are live microorganisms that may help balance the gut microbiome and support digestive health.
