L-Carnitine

L-carnitine is a compound that the body makes by itself from two amino acids, lysine and methionine. Food provides it as well, mainly meat, fish and dairy products; plant foods contain very little of it.

In the European Union, no health claim is authorised for L-carnitine. On this page we therefore describe our products, their formats and their doses, without attributing any effect to them. To find out what the studies actually show, read our L-carnitine guide.

Discovered in 1905, L-carnitine is made by the body itself, mainly in the liver and kidneys, from two amino acids that come from food: lysine and methionine. It is then stored mostly in the muscles.

Lysine is found in meat, fish, dairy products and pulses, among other foods; methionine is found in meat, fish, eggs and some nuts.

• L-Carnitine 3000 mg shots (12 x 80 ml): the most concentrated format, one shot per serving.
• L-Carnitine Liquid 6000 (500 ml): a liquid you measure out.
• L-Carnitine 2000 mg (12 x 700 ml): a ready-to-drink bottle to spread over the day.
• L-Carnitine Water (12 x 500 ml): 500 mg of L-carnitine per bottle.
• L-Carnitine 500 mg (60 capsules): the capsule format.
• Maxi L-Carnitine 1000 mg (90 tablets): the tablet format.

Pick the format that suits you best: the form only changes how you take it.

Follow the dose and directions on your product's label, without exceeding them: depending on the format, one serving provides 500 mg to 3 g of L-carnitine. Consistency matters more than timing. A shot is easy to take before your session; a drink can be spread over the day.

Do not exceed the recommended daily dose. A food supplement is not a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of young children.

Talk to your doctor before starting if you have kidney disease or a thyroid disorder, are on anticoagulant treatment, or are pregnant or breastfeeding. L-carnitine is not intended for children.
