Sentinel Iron is a dietary supplement containing iron, available in a bottle of 100 tablets. This supplement is designed to help prevent and treat iron deficiency anemia by supporting healthy red blood cell production and oxygen transport throughout the body. Iron supplements should be taken under medical supervision as excessive iron intake can be harmful. Common side effects may include stomach upset, constipation or dark stools. For optimal absorption, it's recommended to take iron supplements with vitamin C and avoid taking them with calcium-rich foods or beverages. The amber bottle helps protect the tablets from light exposure. Pregnant women, menstruating women, vegetarians and athletes may have increased iron needs and should consult their healthcare provider about appropriate supplementation.
