I'll be short and sharp because I know you're busy - but STOP wasting your money on l-Carnitine supplements.
They're marketed as something to help you lose weight, but the results are poor.
In these double blind trials and others, subjects did NOT experience anymore fat loss (1,2).
Don't Buy l-Carnitine
Carnitine is an amino acid derivative that does play a role in lipid metabolism is some animals.
So naturally, as some pockets of the fitness industry do so well - the truth has been stretched beyond what's actually correct.
It's subsequently been touted as a "fat burner" for human beings when it's just not efficient in that manner!
And it's a pretty easy sell - the placebo effect works wonders for many people.
But sell one subject l-carnitine - and they'll tell their friends the supplement helped them "see lines they've never seen before bro."
But the other subject achieved that too...
Or better yet - get a lean subject to stand there and be photographed with a bottle of carnitine, then sell it based off that notion!
It's this simple - science does NOT support carnitine as an efficient fat burner that's worth your money.
So don't buy it - instead focus on a solid calorie deficit, adequate protein intake; an eating approach that's easy for you to follow....AND STICK TO!
"Stay Fit, Stay Flexed!"
