I am a 78 year old woman who has suffered for the past few years with the burning feet problem especially at night. About six months ago, I began taking two 200 mg capsules of Alpha Lipoic Acid at bedtime and I am so happy to say that it has helped me considerably. Before trying the ALA, I used an topical Avon product called Foot Works that was somewhat helpful, but now do not need it as the ALA has been the answer for me. I have idiopathic small fiber neuropathy.
