L-Leucine 1000mg | Muscle Building & Strengthening | 60 Veg Capsules
Key Health Benefits
| Use Case | Evidence Summary | PubMed Link |
|---|---|---|
| Muscle Protein Synthesis Activation | L-Leucine is a potent activator of the mTOR pathway, which plays a crucial role in initiating muscle protein synthesis. Studies have shown that leucine supplementation can stimulate muscle protein synthesis, especially when combined with resistance exercise, leading to muscle growth and recovery. | PubMed |
| Prevention of Muscle Loss in Aging | In elderly individuals, leucine supplementation has been found to enhance muscle protein synthesis rates, helping to counteract age-related muscle loss (sarcopenia). This suggests that leucine can be beneficial in preserving lean muscle mass in older adults. | PubMed |
| Enhanced Exercise Performance | Supplementation with L-Leucine has been associated with improved endurance performance and upper body power in athletes. A study involving outrigger canoeists demonstrated that six weeks of leucine supplementation led to significant improvements in rowing time and perceived exertion. | PubMed |
| Improved Recovery Post-Exercise | Leucine, when co-ingested with protein and carbohydrates after physical activity, has been found to improve whole-body protein balance and stimulate muscle protein synthesis, aiding in recovery. This effect is observed in both young and elderly individuals. | PubMed |
Dosage Recommendation
| Goal | Recommended Capsules per Day |
|---|---|
| Muscle Growth & Recovery | 2 capsules daily (providing 1,000 mg L-Leucine), taken post-workout with a protein source |
| Prevention of Muscle Loss (Aging) | 2 capsules daily, preferably with meals to enhance muscle protein synthesis |
| Enhanced Exercise Performance | 2 capsules daily, taken 30 minutes before exercise |
| General Health Maintenance | 1 capsule daily, with or without food |
