Frequently Asked Questions

What is the difference between R-ALA and regular alpha lipoic acid?

Regular ALA supplements contain a 50/50 racemic mixture of R-ALA (the naturally occurring, biologically active form) and S-ALA (a synthetic mirror image with lower biological activity). R-ALA is approximately twice as potent per milligram and is better absorbed. A 300mg dose of R-ALA is roughly equivalent to 600mg of racemic ALA. R-ALA is more expensive but more effective per dose.

Can alpha lipoic acid help with fatty liver disease?

Yes, ALA addresses multiple NAFLD mechanisms: it improves insulin sensitivity (a primary NAFLD driver), recycles glutathione (depleted in fatty liver), reduces oxidative stress in hepatocytes, and may promote weight loss. Clinical studies using 600-1200mg/day ALA show reduced ALT and improved liver imaging. ALA is best combined with diet and exercise modifications for NAFLD management.

Should I take ALA on an empty stomach?

Yes, ALA absorption is significantly reduced by food — studies show up to 30-40% lower blood levels when taken with meals. Take ALA 30 minutes before eating for optimal absorption. If stomach upset occurs on an empty stomach, taking it with a small amount of food is an acceptable compromise, though absorption will be somewhat reduced.
