5-MTHF contains one milligram (1 mg) of (6S)-5-methyltetrahydrofolic acid from a very pure patented glucosamine salt form of 5-methyltetrahydrofolic acid. The formula is contained in a veggie capsule only with microcrystalline cellulose (filler) and silica (flow agent). It contains no magnesium stearate.
5-MTHF, also known as L-5-methyltetrahydrofolate, is one active form in a group of vitamins known as folates. In contrast to folic acid, a synthetic form of folate, 5-MTHF is one of the forms of folate found naturally in foods. In the body 5-MTHF may be converted into any of the other active forms of folate.
Folate coenzymes are responsible for important metabolic functions, including:
Formation of purines and pyrimidines needed for synthesis of the nucleic acids DNA and RNA. This is especially important during fetal development in the first trimester of pregnancy
Formation of heme, the iron-containing protein in hemoglobin
Interconversion of the 3-carbon amino acid serine from the 2-carbon amino acid glycine
Formation of the amino acids tyrosine from phenylalanine and glutamic acid from histidine
Formation of the amino acid methionine from homocysteine (Vitamin B12 as methylcobalamin also is needed for this conversion). Elevated levels of homocysteine have been implicated in a wide range of health issues. In the reconversion of homocysteine to methionine the body uses the methionine to make the important amino acid s-adenosylmethionine (SAMe) which is known to be supportive of healthy moods.
Synthesis of choline from ethanolamine
Formation and maturation of red and white blood cells
Conversion of nicotinamide to N'-methylnicotinamide
When taking folate it is recommended you take adequate amounts of Vitamin B12 as methylcobalamin.
