Sentinel Ferrous Sulfate is a dietary supplement containing 325mg of ferrous sulfate (providing 65mg of elemental iron) per tablet. This supplement comes in a bottle of 100 tablets and is designed to help prevent and treat iron deficiency anemia. Ferrous sulfate is one of the most common and well-absorbed forms of iron supplementation. Iron is essential for producing hemoglobin, the protein in red blood cells that carries oxygen throughout the body. This supplement may be particularly beneficial for individuals with increased iron needs, including pregnant women, menstruating women, vegetarians, and those with diagnosed iron deficiency. Common side effects may include stomach upset, constipation, or darkened stools. It is recommended to take iron supplements with vitamin C to enhance absorption and on an empty stomach. Always consult a healthcare provider before starting iron supplementation.
