L-carnitine Supplements May Reduce Muscle Soreness and Injury

Workout recovery supplements are popular because they allow people to get back to their routines more quickly. A recent study suggests that L-carnitine supplements may help reduce muscle soreness and injury and increase blood flow in both young and older people.


Researchers from Tufts University searched PubMed for human trials that included “carnitine AND exercise AND recovery.” They did not include trials where l-carnitine was given in combination with other products (multi-ingredient supplements) or the outcome was not related to post exercise recovery.


The researchers found that L-carnitine supplementation was linked with reduced muscle soreness and injury and increased blood flow after a workout. They also found that these factors contributed to recovery.


In addition, studies in older adults found L-carnitine can lead to increased muscle mass, decreased body weight, and reduced physical and mental fatigue.


The study was published on March 13, 2018, in Nutrients.


L-carnitine is an amino acid that can be found in red meat, pork, seafood, chicken, and dairy. Additionally, the body produces carnitine naturally.
