The Claim
In healthy young men, supplementation with 1.36 grams of L-carnitine combined with 80 grams of carbohydrate twice daily for 12 weeks increases skeletal muscle total carnitine content by approximately 20%, which is associated with greater whole-body energy expenditure during low-intensity exercise and prevents fat mass accumulation compared to carbohydrate supplementation alone.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If healthy young guys take a certain amount of L-carnitine with carbs every day for 12 weeks, they might store more carnitine in their muscles, burn more energy during light exercise, and avoid gaining fat compared to just taking carbs.

What the research says
1 studyThe study found that taking L-carnitine with carbs twice a day for 12 weeks boosted muscle carnitine and energy burning during light exercise, and stopped fat gain compared to carbs alone—just like the claim says.
