In a healthy body, "methylation" happens over a billion times a second. This is important for converting potentially dangerous homocysteine into one of the body"s most important antioxidants, glutathione. Keeping homocysteine at a healthy low level is also important for maintaining a healthy heart, brain and circulatory system and for maintaining clarity of thought and mind as we grow older. Methylation also helps the body convert homocysteine into SAMe, which helps maintain good mood and flexible joints. One capsule provides: 500mg TMG (Tri-Methyl Glycine).
