What's L-A-C got to do with it?

AIDS: The PWA Health Group will begin carrying L-acetyl-carnitine. Studies show that d4T and ddI may cause neuropathy by lowering L-acetyl-carnitine levels; however, there have been no controlled studies showing that L-acetyl-carnitine therapy is effective. A study involving the elderly showed that L-acetyl-carnitine offered significant improvement in cognitive function, with no serious side effects. L-acetyl-carnitine and L-carnitine are not the same. The strength of L-carnitine varies greatly in the pills available in health food stores and the prescription drug L-Carnitor is recommended.^ieng
