evidence for l-carnitine (incl. l-carnitine l-tartrate)

Our honest take

A plain 500 mg dose of L-carnitine (as Carnipure L-carnitine tartrate) in vegetarian capsules, with nothing else added. L-carnitine has little evidence for fat loss in healthy people who eat a normal diet, so do not expect it to change your results on its own. If you want to try it, this is a clean, honestly labelled option, and the 180-capsule pot is the best value at about 20p a day.

  • You want a simple L-carnitine capsule with no stimulants or extras
  • You eat little or no meat and want to try L-carnitine
  • You are buying it for fat loss: the evidence does not support that in healthy people
  • You have a thyroid disorder or take thyroid medication or warfarin, unless your GP agrees
  • You are pregnant or breastfeeding
The science

L-carnitine (incl. L-carnitine L-tartrate)· evidence: Limited

L-carnitine helps carry fats into cells to be used for energy. Your body makes its own, and meat and dairy supply more, so healthy people eating a normal diet are not short of it. Taking extra does not appear to raise the amount in muscle much, which is one reason it does not act as a 'fat burner'.

Reviews of the trials report a small average drop in weight (around 1 kg) compared with placebo, mostly in older or overweight people, often alongside a diet. There is little evidence of a meaningful effect on fat loss in healthy, active people with a normal diet. Small studies of L-carnitine L-tartrate have looked at muscle soreness after exercise, with mixed results.

There is no authorised health claim for L-carnitine, so we make no claims about its effects. Fat loss comes from a sustained calorie deficit, not from this ingredient.

Typical dose: Studies have typically used 1–3 g a day; liquids and capsules usually give 0.5–3 g per serving

Safety: Usually well tolerated at up to about 2 g a day. Higher doses can cause stomach upset, diarrhoea and a 'fishy' body odour. Speak to your GP first if you take thyroid medication or warfarin, have kidney disease, or have had seizures. Not recommended in pregnancy or breastfeeding without medical advice.
