Sentinel Folic Acid is a dietary supplement containing 800 mcg of folic acid per tablet, with 250 tablets per bottle. Folic acid is a B-vitamin essential for cell growth and DNA synthesis, particularly important during pregnancy for preventing birth defects and supporting maternal health. Folic acid plays a vital role in red blood cell formation, amino acid synthesis, and maintaining a healthy immune system. It is especially important for women of childbearing age and during pregnancy, as it helps prevent neural tube defects in early fetal development. The supplement should ideally be taken from before conception through at least the first 12 weeks of pregnancy. The bottle contains 250 tablets, providing a long-term supply when taken as directed.
