What the AI looks for in Alpha Lipoic Acid Nutritional Supplements
- Form
- Standard alpha-lipoic acid is a 50/50 R/S mix. Products sold as R-lipoic acid should state a stabilised form, such as the sodium salt. Most clinical trials used the standard mix, while unstabilised R-lipoic acid degrades easily.
- Dose
- 600 mg per day is the dose most often studied for diabetic neuropathy. Lower doses have less trial support for that use.
- Timing
- Take on an empty stomach. Food noticeably reduces absorption.
- Blood sugar
- If you take glucose-lowering drugs, monitor your blood sugar when you start. Alpha-lipoic acid can add to their glucose-lowering effect.
Brands that matter
- Doctor's Best: Standard and stabilised R-lipoic acid options.
- Jarrow Formulas: Sustained-release version.
- Life Extension: R-lipoic acid products.
- NOW Foods: Low-cost standard alpha-lipoic acid.
What to avoid
- Unstabilised R-lipoic acid powders.
- Blends with only token amounts of alpha-lipoic acid.
Questions
Is R-lipoic acid better than regular alpha-lipoic acid?
R is the natural form and may absorb better, but most clinical evidence comes from the standard mix. Either is reasonable.
