Moderate 5-Week Exercise Training Program Study

Randomized, double-blind, placebo-controlled trial; 80 participants (age 21-65 years).

Results: Supplementation with L-Carnitine significantly improved perceived recovery and soreness and significantly decreased serum creatine kinase compared to placebo.*1

"Significantly lower heart rate and blood glucose during exercise.*" Icon of person on a bike

Cycling Study

Double-blind, placebo-controlled, pair-matched parallel design; 15 healthy, endurance-trained men (age 23-44 years).

Results: During the Day 15 trial, heart rate and blood glucose concentration were significantly lower during exercise in the L-Carnitine supplemented group compared to placebo.*2

"Utilized 55% less muscle glycogen and 44% lower muscle lactate content*" Icon of person flexing

Skeletal Muscle and Exercise Performance Study

Randomized, double-blind, placebo-controlled trial; 15 healthy, recreational male athletes (age 23-28 years).

Results:  Supplementation with 2 g L-Carnitine increased skeletal muscle total carnitine content by 21% compared to baseline; this was unchanged in control.* Also, the L-Carnitine supplemented group utilized 55% less muscle glycogen and showed 44% lower muscle lactate content compared to control.*3
