How to take L-Carnitine 500 Tabs

Specialists of the manufacturer recommend training athletes to drink 1-2 capsules twice a day. It is best to take the drug in the morning, 30 minutes before training. Pure L-carnitine exhibits its positive properties most effectively in the morning.

Many mistakenly believe that exceeding the dosage will enhance the effect of the substance. This is a misconception. Studies have proven that taking more than 2 grams of L-carnitine per day does not make sense, since there is no additional effect. Its use allows you to enhance the effect of other fat-burning drugs. Most athletes use this supplement in conjunction with drugs such as Methyldrene-25, Black Spider, Lipo 6 Black and others.

L-Carnitine 500 Tabs is allowed to be used together with pre-workout complexes, as well as supplements containing amino acids, gainers. Carnitine is recommended to drink in courses. The duration of one should be a maximum of 30 days. Exceeding the period of course administration provokes a decrease in the production of androgenic carnitine, so you have to drink artificial additives on a regular basis to normalize it.

Do not rely solely on L-carnitine. It will not bring any benefits to the body. Its effect is manifested with regular physical exertion and a balanced diet.
