5-MTHF Vitamin B9 Supplements are a type of dietary supplement that provides an active form of folate, a B-vitamin that plays a crucial role in many bodily processes. Unlike other types of folate supplements, which need to be converted into the active form by the body, 5-MTHF is already in the active form and can be readily used by the body. These supplements are often recommended for individuals who may have difficulty converting regular folate into the active form due to genetic variations or other factors. They are available in various strengths and formulations, and can be found in both tablet and capsule form.
