“L-Carnitine is the new GLP-1.” Not quite.
It’s what a GLP-1 doesn’t do.

A compound built from two amino acids that your body produces on its own and also absorbs from food, and red meat is the richest source. It’s stored mostly in muscle, and was first isolated from muscle tissue in 1905.

Its main role is transport. Fatty acids can’t cross into the mitochondria, the part of the cell that burns fuel, without a carrier, and L-Carnitine is that carrier. Supporting that step is what supplementing it is for. It isn’t a “fat burner” in the sense the internet uses the phrase.

No. GLP-1 medications are prescription drugs that mimic a gut hormone and act on appetite signalling. L-Carnitine is a nutrient that acts on fatty acid transport. Different category, different mechanism, different level of medical oversight. Nothing here suggests one substitutes for the other. If you take or are considering a GLP-1 medication, speak to your doctor.

750mg per 21g serve: one scoop, shaken into 300ml of water or a beverage of your choice. One serve daily.

After training, ideally. Exercise acutely increases metabolic responsiveness, so that’s the most useful window. On rest days take it at the same time each day. Daily consistency matters more than perfect timing.

People who train at least a few times a week and want one daily serve covering protein, creatine, electrolytes, probiotics and micronutrients instead of managing four or more separate products. It isn’t a weight-loss product and it isn’t a replacement for meals.

It replaces the stack rather than adding to it. One scoop after training covers what most people were buying as four separate tubs. The formula is built around lean mass and recovery, which is why L-Carnitine sits beside 15g of protein and 3g of creatine rather than being sold on its own.

You’re covered by a 90-day full refund guarantee, and you can cancel or pause a subscription at any time. If it’s the flavour rather than the formula, the flavour promise lets you swap within 24 hours.

Doses are set at amounts intended to be meaningful rather than label-filling: 15g protein, 3g creatine, 750mg L-carnitine and 420mg of electrolytes per 21g serve.
