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

R-ALA is the form found in the body; most cheap ALA is a 50/50 mix of R and S forms. Na-RALA is a stabilized R-form salt, so 600 mg delivers more of the active R-form than the same weight of a racemic product.

How much biotin is in each capsule?

150 mcg of d-biotin per capsule. It is included because long-term alpha lipoic acid use can depress biotin levels.

Can I take this on an empty stomach?

ALA is usually taken on an empty stomach for absorption, but it can cause nausea or heartburn in some people. Taking it with a light meal is an option if you react badly.

Will biotin in this supplement affect blood tests?

Yes, biotin can skew thyroid and troponin lab results. Tell your doctor you take it, and stop a few days before scheduled labs if advised.

Is 600 mg a good starting dose?

It is on the high side. Many people start at 100 to 300 mg and work up. Talk to a clinician before starting at 600 mg, especially if you take diabetes medication.
