The Active Ingredient Is: L-5-Methyltetrahydrofolate (L-5-MTHF)

L-5-Methylfolate is essentially the most active, methylated form of folate used to support normal metabolic folate status.

This ingredient is provided as L-5-MTHF to bypass common metabolic steps, which is used in allergen-free, high-purity supplement formulations.

What Does L-5-MTHF Do?

L-5-MTHF helps maintain folate status and also plays a role in normal methylation processes which are important for nerve and cognitive function in line with EFSA guidance.

Dr. Lamers of Maastricht University found that 5-MTHF can improve folate status and lower homocysteine, which contributes to healthy metabolic function.
