L-Carnitine is a compound produced by the body that helps to turn fat into energy. It can also be found in animal products like meat, fish and dairy. L-Carnitine is used worldwide by people managing their weight and by athletes for energy production to improve their performance. SynTech uses L-Carnitine Tartrate, a form of carnitine with a better uptake.
Increased levels of L-Carnitine ensure that fats are used as a fuel for muscles, which has several advantages:
- It helps people to lose weight and decrease their body mass index.⁽¹⁾
- Because it increases lipid utilisation, muscle glycogen stores are spared which results in a better performance during low intensity exercise.⁽²⁾
- It reduces muscle lactate accumulation at high intensity exercise, resulting in a better endurance capacity.⁽³⁾

Take 2 caps (= 1 serving) 3 times a day, every day of the week. Always take with a meal or snack that contains carbohydrates.
For optimal results, take 3 – 6 months.
L-carnitine is a non-essential nutrient as it is produced by the body from the amino acids lysine and methionine. It transports long-chain fatty acids that are released from fat tissue into the mitochondria where they are oxidized for energy production. However, muscle carnitine levels are rapidly depleted during exercise and it are those carnitine levels that determine how much fat can be used for energy production. That is why athletes need more l-carnitine and those levels can be increased by correct supplementation. Take a dose of 3000mg per day for longer period of time and always in combination with a meal that contains carbohydrates.⁽⁴⁾ The advantage of taking it with a meal is that it doesn’t affect calorie-intake. This is important for people who take l-carnitine to lose weight and are monitoring their energy balance. Each daily serving contains 4410mg L-Carnitine Tartrate to reach the effective dose of 3000mg l-carnitine.
