|The VO2-max boosting effects of l-carnitine tartrate can be beneficial for almost every athlete.|
As a recent study from the Shahid Chamran University in Iran shows, this could be a mistake. After all, Mostafa Dehghani and his colleagues were able to show that "supplementation of L-carnitine improved effectively the performance by increasing in [sic!] lipid metabolism" (Dehgani. 2015).
But how did the researchers come to this conclusion and are the results relevant for you and me? Well, the first good news is that we are talking about a randomized controlled clinical human study, in which the subjects were not training noobs, but elite wrestlers.
The twenty healthy elite male wrestlers with a mean age of 22.05 ± 2.6 years, mean weight of 77.10 ± 11.65 kg, mean height of 1.79 ± 0.06 m, and mean body mass index of 23.79 ± 2.45 kg/m2 who participated in this single-blind clinical trial were randomly divided into two groups including test and placebo.
- The test group received 3 g of L-carnitine tartrate in 200 ml water and 6 drops of lemon juice.
- The placebo group consumed only 200 ml water and 6 drops of lemon juice.
