4 benefits of L Carnitine
L-carnitine is a type of amino acid. There are several different types of L-carnitine. It’s mostly found in animal products, so vegetarian and vegans are at a high risk of becoming deficient. Luckily it is available in supplement form! 
Increasing exercise endurance
Many studies done over the years have shown L-carnitine to be beneficial to energy production and the endurance. L-carnitine carries fatty acids into our  cells mitochondria where they can be burnt and used for energy. Think of the mitochondria as the cells engine. Supplementing with L-carnitine can be beneficial for endurance sports.
Increases fat-burning and weight loss
With L-carnitines ability to carry fatty acids to our cells mitochondria this leads to increased fat burning during exercise. Studies have shown supplementing with L-carnitine led to a greater amount of weight loss than for those who didn’t. Whilst this can be beneficial for weight loss, just taking the supplement on its own won’t help, a healthy diet, exercise plan and being consistent is key for the best results.
Improves brain function
Studies have shown L-carnitine to be beneficial when it comes to improving cognitive function. Acetyl-L-carnitine has been shown in a study that it could help reverse cognitive decline and it may even have the ability to help improve memory for those suffering from Alzheimers disease.
Regulate blood sugar 
Studies have shown that L-carnitine can help improve insulin sensitivity which can help prevent insulin resistance which can result in high blood sugars and cause type 2 diabetes.
Before taking L-carnitine
If you are thinking of adding L-carnitine supplements to your diet, there can be few side effects such as nausea, vomiting and diarrhoea. Those who have suffered from seizures, have an under active thyroid or on blood thinners should avoid L-carnitine. Pregnant and lactating woman should not use L-carnitine as the safety is unknown.
