Weight Loss Benefits
The same amino acid citrulline that watermelon juice is so rich in, has also been shown in animal studies (due to its conversion to arginine) to interfere with the accumulation of fat in fat cells. It does this by blocking the effects of an enzyme called TNAP involved in fat storage.
Vitamins and Minerals
While perhaps not as impressive as its antioxidant carotenoids or unusual amino acid content, watermelons still contains useful levels of vitamins and minerals.
In the vitamins, watermelon is particularly high in vitamin C, as well as having more than enough beta-carotene that could be converted into vitamin A in your body if needed. There are also smaller amounts of B vitamins.
Watermelon Juice for Kidney Health
Watermelon juice is great for your kidneys, having a highly cleansing effect when you drink it. It helps to flush out ammonia and uric acid and has even been known to help with kidney stones.
Watermelon seeds can have an even more pronounced effect on your kidneys, so it’s recommended to buy your watermelons with the seeds if you’re using the juice for kidney cleansing.
