Explanation:
Detailed explanation-1: -Iron is a mineral that the body needs for growth and development. Your body uses iron to make hemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body, and myoglobin, a protein that provides oxygen to muscles.
Detailed explanation-2: -Take vitamin C with your source of iron. Vitamin C increases absorption of both heme and non-heme iron absorption. Four ounces (1/2 cup) of orange juice is enough to increase iron absorption. Other sources of vitamin C include citrus fruit, fresh bell peppers, strawberries, cantaloupe, and fresh broccoli.
