What Vitamins Are in Peanuts?

According to the Peanut Institute, peanuts contain fats, protein and fiber that are beneficial in promoting health and reducing the risk of chronic diseases. Peanut butter and peanuts contain almost half the 13 essential vitamins that are necessary for body growth and maintenance.

Vitamin E

Vitamin E is an antioxidant that protects the vitamin A in our bodies. In addition, it protects our cells and tissues from damage. Vitamin E has been known to boost the immune system by stimulating production of natural killer cells that destroy cancer and germ cells. It can also contribute to reducing the risk of cardiovascular disease. One ounce of dry-roasted peanuts contains 25 percent of the recommended daily intake of vitamin E. The Mayo Clinic states that the daily dietary amount for adults is 15 mg.


Niacin is a B vitamin and is important in the release of energy from foods we consume. It also aids in maintaining healthy skin as well as maintaining the digestive tract and nervous system. According to Vitamins-Supplements, niacin is powerful in lowering cholesterol levels, alleviating depression and insomnia; a niacin deficiency affects every cell in your body. Deficiencies may also lead to muscle weakness and skin lesions. One serving of peanuts contains 19 percent of the recommended daily intake of niacin.


Folate, also known as folic acid, is essential in many body functions. Our bodies need folate for DNA repair and DNA synthesizing. During periods of rapid cell division, folate is necessary for growth and producing healthy red blood cells. Folate deficiencies carry many health risks, such as cancer development due to DNA synthesis and neural tube defects in developing embryos. The Office of Dietary Supplements states that the recommended daily dosage of folate for male and female adults is 400mg. A single serving of peanuts offers 10 percent of the recommended daily intake of folate.


Peanuts contain riboflavin, and vitamin that is necessary to maintain healthy skin and normal eye functioning. Riboflavin is a water-soluble vitamin that is not stored in the body. Leftover amounts of this vitamin leave the body through the urine; therefore, it must be restored daily. According to the Institute of Medicine, the daily recommended intake of riboflavin varies on age and gender 1.
