Sentinel Iron 28 Mg is a dietary supplement containing 100 tablets designed to help maintain healthy iron levels in the body.

Iron supplements are commonly recommended for individuals with iron deficiency or increased iron needs, such as pregnant women, menstruating women, athletes, and vegetarians. For optimal absorption, iron supplements should be taken on an empty stomach or with vitamin C. Common side effects may include constipation, nausea, or dark stools. Always consult a healthcare provider before starting iron supplementation, as excess iron intake can be harmful.
