L-carnitine in coffee: what it is and what to expect
“Slimming coffee” usually means ordinary coffee with L-carnitine added. A short guide to both ingredients.
What L-carnitine does
L-carnitine is a compound the body makes from two amino acids. Its job is transport: it carries fatty acids into the mitochondria, where they are burned for energy. Red meat and dairy are the main sources in food.
Does more of it help?
The logic on the box is that more carnitine means more fat burned. In practice most healthy people already have what they need, and trials of supplements have found, at most, modest effects on weight. It is an ingredient to be realistic about.
The coffee part
Caffeine is the ingredient you will actually feel. It sharpens alertness and can blunt appetite for a while. Food-safety authorities generally describe up to about 400 mg a day as safe for healthy adults, and advise no more than 200 mg in pregnancy.
Count every cup, tea and energy drink towards that, and avoid caffeine late in the day if it affects your sleep.
A fair way to try it
If the appeal is a routine you will keep, a coffee sachet is a reasonable format: you were going to drink coffee anyway. Follow the suggested use on the box and judge it alongside what you eat and how much you move.
