Drinking 1 to 2 cups of watermelon juice daily is generally safe and hydrating, but adjust based on your overall fluid intake and dietary needs.
Watermelon juice is a refreshing, nutrient-packed drink that offers numerous health benefits. But how much should you drink per day? This guide covers ideal intake, health benefits, and expert recommendations.
Recommended Daily Intake of Watermelon Juice
Most nutritionists suggest 1-2 cups (8-16 oz) of watermelon juice daily. This provides hydration and nutrients without excessive sugar intake.
Factors Affecting Ideal Amount
- Activity level: Athletes may benefit from 2-3 cups
- Health conditions: Diabetics should limit to 1 cup
- Diet: Accounts for natural sugars in your daily intake
For optimal nutrient absorption, consider using a cold press juicer to make your watermelon juice.
Key Health Benefits of Watermelon Juice
1. Superior Hydration
Watermelon is 92% water, making its juice excellent for hydration. It’s more effective than plain water for athletes according to sports nutrition research.
2. Rich in Lycopene
Watermelon contains more lycopene than tomatoes – about 11mg per cup. This antioxidant supports heart health and may reduce cancer risk.
3. Contains L-citrulline
This amino acid helps reduce muscle soreness. Studies show 286-1,266mg per 2 cups of watermelon juice aids post-workout recovery.
4. Vitamin C Powerhouse
One cup provides 30% of women’s and 26% of men’s daily vitamin C needs, supporting immunity and iron absorption.

Potential Drawbacks and Precautions

As a high-FODMAP food, excessive amounts may cause bloating in sensitive individuals.
Making the Best Watermelon Juice
For optimal nutrition:
- Use ripe, organic watermelon
- Include some white rind (contains citrulline)
- Juice with a quality juicer
- Drink immediately or store for max 24 hours

Watermelon Juice vs Whole Watermelon
While juice is convenient, eating whole watermelon provides more fiber. Consider alternating between both forms for balanced nutrition.
