There is preliminary evidence that ALA, taken in the amount of 150-200mg daily for one month, improves visual function in people with glaucoma. ALA has been shown to inhibit the replication of the HIV virus in the test tube. Dr. Burt Berkson reports evidence of pancreatic cancers with liver metastases recovering through ALA/Naltrexone treatment.
The amount of ALA used in research to improve diabetic neuropathies is 600-1800 mg per day and 200 mg per day for glaucoma. 200 mg per day is recommended for general antioxidant protection in healthy people. Because of its chelation effect, one should only cautiously exceed recommended dosages. Use only r-ALA and not the s form of ALA as that is a synthetic version and not as effective.
