Sentinel Folic Acid 800mcg is a dietary supplement containing 250 tablets. As a member of the B vitamin group, folic acid plays an essential role in maternal health, neural tube formation, blood cell production, and immune system function. Folic acid is particularly important during pregnancy and should be taken from when contraception is stopped through the first 12 weeks of pregnancy. It contributes to maternal tissue growth, normal blood formation, homocysteine metabolism, immune system function, and helps reduce tiredness and fatigue. The 800mcg dosage provides a higher concentration compared to standard supplements.
