L-CARNITINE AND MUSCLE CRAMPS
Atif Zaman, MD, MPH reviewing Nakanishi H et al. Clin Gastroenterol Hepatol 2015 Aug
A recent study showed that L-Carnitine supplements improved leg cramps in 88% of patients who had cirrhosis of the liver. This was an observational study (not scientific) but the results were consistent.
Leg cramps are very common in patients who take Statins (Lipitor, Crestor) for their cholesterol. Many treatments have been tried including co-enzyme C10, calcium, Magnesium, vitamin D, salty foods, fluids, etc. but I am not aware of any study actually proving any of these remedies actually work. It’s basically trial and error- if it works great.
The researcher hypothesize that L-carnitine works by affecting energy metabolism. The dose used was 300mg 3-4 times daily
The question, since it was only studied in liver patients, could it work when cramps are caused by other reasons?
