Decades of research and studies conducted on its performance deem it to be safe and effective. In fact, today many health enthusiasts rely greatly on L-Carnitine to meet their fitness goals. 

After initial success in the 80’s when it was sold in the form of energy drinks, L-Carnitine supplement witnessed a decline in its popularity after the emergence of stimulant based products in the health and fitness market.

It Is Formed Naturally In Your Body

In human body, L-Carnitine is formed naturally by lysine and methionine. They are the kind of amino acids found in the liver and the kidneys. After the production, L-Carnitine is saved in the brain, heart and even the sperm. If you are not up for supplements and want to get all your L-Carnitine organically then consider adding amino acid rich foods in your diet. Avocado, soybeans and red meat are the excellent sources of L-Carnitine.

A Great Anti-Oxidant 

When carnitine molecule gets attached to the acetyl group it forms a very powerful compound in human body. This active compound called acetyl-L-Carnitine acts as a power packed antioxidant, which is capable of passing blood brain barrier. Researchers around the globe believe that this compound can potentially provide protection against neurodegeneration. Though studies are still under process, initial outcomes have shown great potential of acetyl-L-Carnitine in preventing/curing degenerative conditions like Alzheimer’s. 

Helps In Weight Loss

People often buy L-Carnitine as a powerful weight loss tool. This has been supported by the studies that have shown how oral consumption of L-Carnitine can reduce fat mass, increase muscle mass and reduce fatigue. All these things play a vital role in healthy weight loss. 

Helps Build Muscles

Benefits of whey protein are nothing new to a fitness enthusiast, which makes it the most liked post workout meal. There is nothing wrong in this as well because whey is an excellent source of essential amino acids that help in repairing of muscle fibers after intense training. 

But, if you wish to get all bulked up then consider making optimum use of L-Carnitine supplements. According to research, L-Carnitine has the ability to enhance the insulin action on muscle cells, which helps in keeping glucose levels low. Glycogen repletion is another department in which L-Carnitine can be of great use.

Improves Blood Flow To The Muscles

Another great function of L-Carnitine supplementation is that it can significantly improve the blood flow into skeletal muscles. The increased blood flow means more nutrients, more hormones and availability of more oxygen during intense workouts. 

Increase in androgen receptors

Testosterone enjoys a very sought after status in the niche fitness segment. Increase in your testosterone levels means more time to build muscles and cut body fats. Carnitine supplements have positive effect on your body’s testosterone levels that also give boost to androgen receptors found in your muscles.

Gives Best Results With Carbs

Researches have shown that carnitine supplementation works best when the insulin levels in your body are a bit high. This why it is often suggested to take carnitine supplement with carbs as they maximize the absorption of the supplement. Even if there is no insulin in your body, L-Carnitine can easily perform its job by getting absorbed in your muscles, intestines, and even in the brain.

Effective In The Long Run

Stimulant based supplements are known to be ineffective when taken for extended periods of time. Their prolonged usage can also be dangerous as they trigger your body to get used to them and would require increase in the dosage over the time. 

But, that is not the case with L-Carnitine, especially when you are taking it as pre-workout drink.
