Studies have shown that a ‘food supplement’, known as alpha lipoic acid, has been beneficial with regards to Burning Mouth Syndrome and the related Idiopathic Dysgeusia.

It has been shown that α-Lipoic Acid is effective in the treatment of diabetic-related neuropathy as well.

The studies were conducted in part, by Professor Scully of the Eastman Dental Institute.

Suggested dose regime for α-Lipoic Acid is:

600 mg per day orally for 20 days followed by 200 mg per day for 10 days.

α-Lipoic Acid can be bought online far cheaper than from high street shops.
