Effects of Vitamin D Supplementation in Combination With Exercise Training on Body Composition and Muscular Strength in Adults: A Systematic Review and Dose-Response Meta-Analysis of Randomized Controlled Trials
Study Details
This new meta-analysis compiled data from 28 studies (1675 participants) to establish the additive effects of vitamin D supplementation to exercise for…
…body composition and strength outcomes in adults 🔍
Key Findings
💊 Vitamin D supplementation led to significantly enhanced 25(OH)D levels (+34 nmol/L)
📈 This increase was evident in both healthy and unhealthy adults
No significant effects were observed for…
❌ Bodyweight
❌ BMI
❌ Fat Mass
❌ Body Fat %
❌ Fat Free Mass
❌ Leg Press Strength
However, positive effects were seen for both…
🦵 Knee extension strength
👊 Handgrip strength (in older adults)
Conclusion
These results suggest that vitamin D does not offer significant additive benefits to exercise training for body composition or strength ❌
This is not to say that vitamin D does not offer benefits in other areas (e.g. immunity, bone health) but for strength and body comp, other strategies (e.g. protein / creatine) are likely more influential ✅
