Maybe she's born with it, maybe it's carnitine!

Good morning.

One of the background questions for new clients regards their current and recent supplementation stack, so I can see what supplements are being used, and ideally why they have been taking them.

One of the most common are thermogenics (fat burners).

The premise of thermogenics are that they raise your metabolism to increase energy expenditure, without any additional exercise.

However, most of the legal thermogenics do very little - to the point you would burn more energy walking to the shop to buy them, rather than from taking the supplement itself.

But that doesn’t stop people buying them.

One ofthe the ‘go-to’ supplements is L-carnitine. 

The ‘L’ means left enantiomer. All amino acids/anything related to the world are left enantiomers, so that’s irrelevant (but does sound sciency).

Carnitine transports fatty acids into the mitochondria - the powerhouse of a cell - where it can be oxidised to create energy. 

It plays an important role in fat oxidation - without carnitine, fatty acids cannot get into the mitochondria to be oxidised.

The theory of supplementation goes along the lines of take more carnitine, burn more fat. 

Unfortunately, it doesn’t work like that.

A lack of carnitine is not a limiting factor for fat loss, and increasing carnitine concentration won’t increase fat oxidation.

Instead, you need to give the body a reason to mobilise stored fat as a fuel source, ie. create an energy deficit.

So if you’re taking carnitine, you can throw it out now. It won’t do you any harm, but it won’t help you burn an additional fat either.

If you’re taking any thermogenic supplements, or think you might be, write back to me with the product and ingredients, and I might be able to help you out.
