Vitamin D supplementation enhances acute muscle protein synthesis ☀️💪
Potential benefits to muscle gains.
Long-Term Effects of vitamin D supplementation on myofibrillar protein synthesis rates in resting and exercised fed skeletal muscle of healthy adults
Study Details
This new paper recruited 17 healthy adults to a study where they supplemented with either…
☀️ 3,000 IU vitamin D3
💊 Placebo
Supplements were provided daily.
After 12-weeks, participants performed resistance-exercise followed by 22g whey protein 🥤
Key Findings
🩸 Vitamin D supplementation led to a significant 75% increase in blood levels
Placebo remained unchanged.
📈 Muscle protein synthesis (MPS) rates significantly increased from 0 - 240 min post-exercise
But there were no changes between groups ❌
However, vitamin D did lead to significantly greater …
✅ Leucine and essential amino acid concentrations
✅ Muscle protein synthesis rates
…at 0 - 60 min after consuming protein post-exercise ⏰
Conclusion
Chronic vitamin D supplementation may promote an earlier anabolic response after exercise + protein 📈
This may have applications for enhanced recovery, strength and muscle adaptations 💪
