Classification of folate and the activity profile of 5-methyltetrahydrofolate

Folate can be classified according to its source as natural folate and synthetic folic acid, and according to its activity as inactive folic acid and active folate.
Inactive folic acid is folate that is not physiologically active in itself and refers exclusively to synthetic folic acid. In contrast, active folate is folate that is physiologically active in its own right and can be absorbed and used directly without metabolic processes.

Active folate refers to a group of substances including dihydrofolate, tetrahydrofolate, 5,10-methylenetetrahydrofolate, 10-formylfolate and L-5-methyltetrahydrofolate. L-5-methyltetrahydrofolate is the most active form of folate, which is essential for the body's vital activities and is the key product of the active metabolism of synthetic folic acid, as well as being the main component of natural folate.

Magnafolate is the unique patent protected C crystalline L-5-Methyltetrahydrofolate Calcium salt (L-5-MTHF Ca) which can get the purest and most stable bio-active folate.
Magnafolate can be absorbed directly, no metabolism, applied for all people.
