Get a metabolically active form of folic acid with Life Extension's Optimized Folate L-Methylfolate. Folate is involved in neurotransmitter synthesis and critical enzymatic reactions throughout the body, specifically promoting good cardiovascular health and nervous system function. Those who take ordinary folic acid supplements, however, may not be experiencing its full spectrum. This is because folic acid is itself not biologically active. That's why Life Extension developed this metabolically active supplement, featuring 1,700 mcg DFE.<br/><ul><li><p>Metabolically active form of folic acid</p></li><li><p>1,700 mcg DFE (425% daily value) per vegetarian tablet</p></li><li><p>Non-GMO</p></li><li>Gluten Free, Non-GMO</li></ul>
