In watermelon seeds, we also find niacin, a B vitamin, extremely necessary for the maintenance of the nervous system, digestive system, and skin elasticity. Also in the seeds, we find vitamins such as thiamine, riboflavin, vitamin B6, and pantothenic acid.

Another benefit of consuming watermelon seeds is the intake of minerals such as magnesium, phosphorus, iron, potassium, sodium, copper, manganese, and zinc, helping muscles and joints.
As for the melon core, it contains extremely little fat and cholesterol. With the help of citrulline (found especially in the peel), the elimination of ammonia from the liver is favored.

Citrulline also reduces oxidative stress, dilates blood vessels, and gives us extra energy.

The melon core also contains vitamins A, C, D, E, B6, and B12, pantothenic acid, iron, calcium, magnesium, potassium, phosphorus, zinc, and selenium. Vitamins, along with antioxidants, help strengthen the immune system, and prevent heart disease, joint inflammation, and even certain types of cancer – colorectal, prostate, breast, or cervical.

Watermelon is richer in lycopene than tomatoes, being a powerful antioxidant that lowers bad cholesterol, and prevents cardiovascular disease, cataracts, and osteoporosis.
