Watermelon (Fresh) Overview
Watermelon is exceptionally high in lycopene - providing more than tomatoes - along with citrulline, an amino acid that may improve blood flow and exercise performance. This hydrating fruit is 92% water while providing vitamin C and antioxidants. Despite being sweet, watermelon is low in calories and may support heart health and recovery.
Why Watermelon (Fresh) Helps With Optimal Hydration
Optimal hydration goes beyond just drinking water - it requires balancing fluid intake with electrolytes (sodium, potassium, magnesium) and accounting for individual needs based on activity, climate, and body size. Even mild dehydration impairs physical and cognitive performance.
