If you’re trying to manage your body goals and you feel like the results aren’t coming, it might be time to add L-Carnitine or Acetyl L-Carnitine to your stack. L-Carnitine is an amino acid derivative that is mainly found in products like meat and fish. It is produced in the body from Lysine and Methionine and is best known for its ability to hit you body targets.

L-Carnitine is one of the most reliable thermogenics on the market and can help you improve your results when consumed alongside a balanced diet and training regime.


L-Carnitine is known for transporting long-chain fatty acids to the cells’ mitochondria, where they are oxidised for fuel, which can be used as energy. The main difference between L-Carnitine and Acetyl L-Carnitine is that ALC is more easily absorbed from the gut and may support cognitive function.

For the best weight support supplements, Evolve L-Carnitine delivers a 100% pure formula that is unflavoured and designed to support your body goals. Gen-Tec’s L-Carnitine formula is 100% pure and pharmaceutical-grade and fast-absorbing. Want more?

L-carnitine should be safe and free of side effects if you’re consuming 2 or fewer grams. In long-term use, there may be mind side effects like nausea and stomach discomfort. If you experience any side effects, you should discontinue use and consult a GP for advice (Mawer, R. 2018).

How does L-Carnitine work to promote weight loss?

L-Carnitine works by stimulating your body into burning more triglycerides (type of fat found in your blood). L-Carnitine promotes the use of triglycerides as an energy source in place of carbohydrates. Supplementing with L-Carnitine can help your body oxidise those fatty acids (triglycerides), allowing your body to spare its supply of glycogen and burn more fat by using it as a fuel source (The O’Brien Clinic).

How much L-Carnitine should I take for weight loss?

If you’re supplementing with L-Carnitine, follow the nutritional panel on the back for directions on how much to take. The general recommended dosage is approximately 1-3 grams per day (Johnson, J. 2020). However, this is dependant on your specific goals, health and fitness regime.

When should I take L-Carnitine?

If you are trying to improve your weight-loss results, supplementing with L-Carnitine may help you enhance your results. Additionally, if you are deficient in carnitine, a supplement may help you replenish yourself.

L-Carnitine should be safe to take as long as it is taken in accordance with the recommended dosage on the nutritional panel and in line with a balanced diet. However, if you are pregnant, breastfeeding, prone to seizures, suffer from hypothyroidism or have any other allergies, prescription medications, or medical conditions, then you should check with a GP before consumption (WebMD).

No. In fact, L-Carnitine may actually support the reduction of acne. L-Carnitine helps to enhance the metabolism of fats and oils, which helps to reduce the excess sebum produces by the skin. Less sebum means acne-causing bacteria have less food, potentially assisting with the reduction of acne (Widrin, C. 2015).
