L-Carnitine is an amino acid derivative synthesising from lysine and methionine, with the primary function of transporting long-chain fatty acids across the inner mitochondrial membrane where they undergo beta-oxidation for energy. Without adequate L-carnitine, fatty acids cannot efficiently enter mitochondria. Dietary sources are meat and dairy, so vegans are at higher risk of suboptimal carnitine status. Clinical evidence: (1) Fat metabolism: a 2011 Journal of Physiology study found 24 weeks of 2g L-carnitine daily significantly increased muscle carnitine content and reduced carbohydrate burning. (2) Exercise recovery: a 2018 meta-analysis of 10 RCTs found L-carnitine reduced markers of exercise-induced muscle damage and delayed onset muscle soreness. (3) Male fertility: 2x 2g per day L-carnitine improved sperm motility per a 2012 meta-analysis. We use L-Carnitine L-Tartrate, the most studied form for exercise performance.

    Trusted brand

    I trust Medibro because they are transparent about what is in their products and actually dose things correctly. So many brands underdose, not this one. Proper amounts that match the science.

    Good, but allow time to work

    Do not expect overnight results. Like any quality supplement, you need to be consistent. After 8 weeks I have noticed clear benefits. Sticking with it.
