The appropriate amount of 5-ALA depends on the product type, the amount contained in each tablet, the purpose of intake, physical condition, underlying diseases, and other medications being used. Commercially available 5-ALA supplements are health foods, and unlike diabetes medications, they do not have a fixed “prescribed dose.”

Clinical studies have reported the use of 5-ALA together with SFC at doses of up to 200 mg per day, but these were controlled studies conducted under research conditions. Some commercially available products contain 50 mg per tablet, and some people may take around two tablets per day, but this does not mean that such an amount is appropriate for everyone.

People undergoing diabetes treatment, those using insulin or glucose-lowering medications, those with kidney or liver concerns, and those who are pregnant or breastfeeding should not decide the dose on their own. They should consult a physician or specialist.
