I was told recently by a fellow fell runner (a reliable source i know ) that taking Cod Liver oil can help with cramp as it aids the mucles in the absorbsion and transportation of Lactic Acid. It is ofcourse a build up of Lactic acid in the muscles which causes cramp. I was under the impression that this build up of lactic acid came from the increase in anaerobic respiration, that is to say that cells are respiring without oxygen due to the increased workload of running. This would suggest to me that cramp is linked with fatigue alone.
Any thoughts on the effectiveness of Cod Liver oil?
