Sentinel Folic Acid 400mcg is a dietary supplement containing 100 tablets of folic acid, a B-vitamin essential for cell growth and DNA synthesis. It's particularly important during pregnancy for proper fetal development and helps prevent neural tube defects when taken before and during early pregnancy. Folic acid is crucial for red blood cell formation, amino acid synthesis, and supporting a healthy immune system. It contributes to maternal tissue growth during pregnancy and should be taken from the time contraception is stopped through the first 12 weeks of pregnancy. The supplement helps reduce tiredness and fatigue while supporting normal homocysteine metabolism. As with any supplement, consult your healthcare provider before use, especially if pregnant or planning pregnancy.
