With the word primarily in the forefront, it should come as no surprise that watermelon is a great source of hydration as watermelon is actually more than 90% water! Watermelon is also a great source of Vitamin C, which can help boost your immune system and help fight off infection. It's also rich in vitamin A, potassium, and lycopene – vitamins integral for a happy, healthy heart! Another great health benefit of watermelon is that it contains antioxidants that may reduce inflammation, lower blood pressure, protect against cancer-causing free radicals, and even offer sun protection!
