Vitamin C

Vitamin C (ascorbic acid) is a water-soluble vitamin, which is needed by the body to form collagen in bones, cartilage, muscle, and blood vessels. Dietary sources of vitamin C include fruits and vegetables, particularly citrus fruits such as oranges.

Vitamin D

Vitamin D is found in many foods, including fish, eggs, fortified milk, and cod liver oil. The sun also adds to the body's daily production of vitamin D, and as little as 10 minutes of exposure is thought to prevent deficiency.

Vitamin E

Vitamin E is a fat-soluble vitamin with antioxidant properties. Vitamin E exists in eight different forms: alpha-, beta-, gamma-, and delta-tocopherol; and alpha-, beta-, gamma-, and delta-tocotrienol.
