Alpha-Lipoic Acid In GlycoAid

The Research Behind Alpha-Lipoic Acid

Alpha-lipoic acid has the second strongest clinical record in this formula, and it is important to say what that record is actually about. The substantial evidence is in diabetic peripheral neuropathy, where intravenous and oral alpha-lipoic acid have been studied in large German trials with generally positive results on nerve pain symptoms. The evidence for effects on blood glucose itself is considerably thinner.

What Dose The Studies Actually Used

The neuropathy trials typically used 600 mg a day, sometimes 1,200 mg. Like berberine, that figure exceeds what a shared 500 mg blend can deliver, and the same honest caveat applies.

Alpha-Lipoic Acid: Cautions Worth Knowing

Generally well tolerated. It can cause mild digestive symptoms and, rarely, a skin rash. There is a theoretical interaction with thyroid medication and with chemotherapy agents that is worth raising if either applies. Anyone with a thiamine deficiency, which is more common in heavy alcohol use than people expect, should address that first.

What Alpha-Lipoic Acid Is Not

Alpha-lipoic acid and lipoic acid and thioctic acid are the same compound. What is different is the form: the R-isomer is the biologically active one and most inexpensive supplements contain a fifty-fifty racemic mixture of R and S. A label saying only alpha-lipoic acid is almost certainly the mixture.

Finding Alpha-Lipoic Acid Outside A Capsule

Small amounts occur in spinach, broccoli, tomatoes and organ meats, but nothing you could eat delivers what the trials used. On a label, the distinction that matters is R-lipoic acid versus a plain racemic mixture; the R-isomer is the biologically active one and an unspecified label almost always means the mixture, which is why the price gap between two apparently identical products can be large.
