The evidence in words
How much to take
1–2 g/day (L-carnitine L-tartrate for exercise recovery; acetyl-L-carnitine for cognitive/neuropathy uses). Chronic use needed to shift tissue levels.
Timing & separation
There are no strict timing conflicts on record for L-Carnitine; consistency matters more than the exact hour for most goals.
Why the dose is what it is
Beyond fat transport, carnitine supplementation appears to reduce exercise-induced muscle damage and improve blood flow and androgen-receptor density in some studies, which is why the recovery evidence outshines the fat-loss evidence.
Bottom line
Not the fat-loss shortcut it's sold as. Reasonable for exercise recovery and certain clinical fatigue states; effects are modest and require consistent dosing.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
