Is R-lipoic acid better than regular alpha-lipoic acid?

R-lipoic acid is the natural, active enantiomer; regular alpha-lipoic acid is a 50/50 mix of R and S forms. Some people prefer the R-only form, but head-to-head human trials are limited, so treat claims of superiority as plausible rather than proven.

How much R-lipoic acid does one capsule contain?

Each vegetarian capsule supplies 480 mg of R-lipoic acid, with 28 mg of sodium. The label directs one capsule daily, preferably on an empty stomach at the same time each day.

Is this supplement vegetarian and gluten free?

Yes. The capsule is vegetable cellulose, the formula is non-GMO and gluten free, and it fits vegetarian diets. Other ingredients are vegetable stearate and silica.

Is $33.94 a good price for this bottle?

Amazon lists it at $33.94 as of November 4, 2026, and it is the only new price on record, so there is no recent range to compare against. Check the bottle size and capsule count before judging value per dose.

Can I take it with food or other supplements?

The label says preferably on an empty stomach, so take it away from meals if you can. R-lipoic acid may lower blood sugar, so check with a doctor if you take diabetes medication or blood thinners.
