evidence for acetyl-l-carnitine
Our honest take
Each capsule combines 320 mg of acetyl-L-carnitine arginate with 300 mg of standard acetyl-L-carnitine, taken three times a day. The arginate form is promoted for brain health, but the research behind it is mostly in animals and cells, and there is not enough good evidence that ALCAR in any form helps healthy people. It costs about 93p a day, roughly three times the price of a plain ALCAR capsule, which we think is hard to justify.
- You specifically want the arginate form and accept the evidence is very limited
- You prefer a vegetarian capsule from a long-established brand
- You want value: plain ALCAR capsules cost a fraction of the price
- You take thyroid medication, blood thinners or blood pressure medicine, unless your GP agrees
- You are pregnant or breastfeeding
The science
Acetyl-L-carnitine· evidence: Insufficient
Acetyl-L-carnitine is a form of carnitine, which the body makes itself and which helps move fat into cells to be used for energy. It is marketed for energy and brain health. There is not enough good evidence that taking it improves exercise performance or energy in healthy people who eat a normal diet.
There is no authorised health claim for it, so we make no claims about its effects.
Typical dose: Products usually provide 0.5–2 g a day
Safety: Can cause stomach upset in some people. Speak to your GP first if you take thyroid medication or blood thinners.
