Effects of Citrulline or Watermelon Supplementation on Body Composition: A Systematic Review and Dose–Response Meta-Analysis
Study Details
This new meta-analysis compiled data from 21 studies (578 participants) to establish the effects of l-citrulline on body composition 🔍
Here is what they found ⬇️
Key Findings
💊 Supplement dose ranged from 0.5 - 10 g/day
🗓️ Intervention duration ranged from 3 - 12 weeks
Results showed that l-citrulline has no substantial effects on…
❌ BMI
❌ Body weight
❌ Fat mass
❌ Waist circumference
❌ Body fat %
❌ Fat-free mass
However, subgroup analyses did show that for participants over 40 yrs, doses of > 6 g/day can reduce fat mass 👴🏻
Plus interventions lasting 3 - 8 weeks can be associated with improved fat free mass 📈
Conclusion
L-citrulline appears to have no overall effect on body composition ❌
Using this supplement for body composition outcomes is likely a waste of money 💸
