Watermelon Juice Powder
Also known as: Citrullus lanatus fruit powder, Watermelon extract powder, Watermelon concentrate
Watermelon juice powder is a concentrated form of watermelon fruit containing naturally occurring citrulline, lycopene, and other phytonutrients. Limited clinical evidence supports its use for cardiovascular and exercise performance support, primarily via citrulline content.
Primary uses
- Nitric oxide support
- Exercise performance and endurance
- Cardiovascular health
- Hydration support
How it works
- Citrulline conversion to arginine and nitric oxide production
- Lycopene antioxidant activity
- Natural electrolyte content (potassium)
Dosage
- Typical range
- 1-2 tablespoons (5-10 g) daily mixed with liquid
- Timing
- Pre-workout (1-2 hours before exercise) or daily
- With food
- Can be taken with or without food; mixing with liquid recommended
- Duration
- Consistent daily use recommended for best results; effects may take 2-4 weeks
- Special populations
- Generally safe for most adults; individuals with FODMAP sensitivities should note watermelon is low-FODMAP
Forms
- Powder· 70/100
Safety
Common side effects
- Minimal; well-tolerated as a whole food
- Possible mild gastrointestinal effects in sensitive individuals
Contraindications
- No major contraindications identified
Evidence notes
While watermelon contains citrulline (which has B-grade evidence), whole watermelon juice powder studies are limited and results are mixed. Most evidence comes from concentrated citrulline isolates rather than whole powder form.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
