L-Carnitine Supplements

Shop L-carnitine at Elite Supps. L-carnitine is an amino-acid derivative with a well-defined job in the body: it helps transport fatty acids into your cells' mitochondria, where they are used to produce energy (1). That role makes it a popular choice for active people and anyone supporting fat metabolism as part of a calorie-controlled diet and regular exercise. We stock L-carnitine in capsules and powders from trusted brands. Every member of our team is a certified nutritionist, so you can choose with confidence.

What L-Carnitine Does

L-carnitine's main role is shuttling fatty acids into the mitochondria to be used for energy. Because it works without caffeine, it is a staple of stimulant-free fat burners and a popular addition to a fat loss routine. Some research has also looked at L-carnitine and exercise recovery, with results varying between studies (1). It supports your training and fat metabolism; the calorie deficit drives weight loss.

Forms of L-Carnitine

  • L-carnitine L-tartrate (LCLT) - a popular form for exercise and recovery.
  • Acetyl-L-carnitine (ALCAR) - crosses into the brain, often chosen for a focus angle.
  • Liquid and powder - convenient, often flavoured, easy to add to a shake.

How to Take and Safety

A common dose is around 1 to 3 grams a day - follow the directions on your product. Capsules are easy on the go; powders and liquids mix into a drink or pre-workout. L-carnitine may interact with some medications, including blood thinners and thyroid medication, so if you take any prescription, are pregnant or breastfeeding, or have a health condition, talk to your healthcare professional first.
