L-carnitine
Dear DietDoc
CyberDoc suggested I ask you this, as he was not sure: I have been diagnosed with unusually high levels of L-carnitine. What could have caused this, and do you know what symptoms I would experience as a result? ( I suffer from CFS/M.E., I don't however have a high animal protein diet - only eat red meat about twice a week)
Thanks

Dear Mia
I must admit that I have also not come across this condition before. However, high levels of L-carnitine in the body could be due to 3 things: a) a derangement in synthesis - the human body is capable of synthesising L-carnitine in the kidney from the amino acids lysine and methionine - thus an abnormality in synthesis could be responsible. I am not sure how this could be determined, but it may be possible for a path lab to identify such a problem b) high intakes of foods rich in lysine (not only red meat, but also milk and dairy products) could cause an increase in production c) high intake from supplements - check every supplement and herbal product you may be taking to see if they contain L-carnitine and stop taking them.
I do hope this problem will soon be resolved.
Best regards
