Long-term studies show that 9 weeks of L-Carnitine supplementation (2 g/day) in resistance-trained males enhances anaerobic performance, reduces exercise-induced oxidative stress, and improves markers of recovery without adverse effects

This vasodilatory effect may contribute to improved blood flow to injured tissues and enhanced healing capacity

The precise timeline based on clinical trial tracking: Weeks 1-3: Mild symptoms beginning, most patients adapting to medication Weeks 4-8: Peak side effect period highest nausea, GI symptoms at their worst Weeks 9-12: Rapid improvement, most GI symptoms resolving Weeks 13-24: Minimal symptoms for most, discontinuation rate drops to under 2% Weeks 25-48: Essentially no side effects for 85%+, focus shifts to weight maintenance According to research published in the New England Journal of Medicine on GLP-1 agonists, this pattern is consistent across the entire class of incretin-based therapies
