Dosage protocol

Alpha-Lipoic Acid dosage

Evidence-based dose range, timing, and adjustment guidance for Alpha-Lipoic Acid. Always start at the low end and titrate; individual response varies and dose-response curves are not always linear.

Standard range

300–600 mg

Frequency

1-2 doses

Half-life

1h

Onset

Starting dose

Start at 300 mg — the lower end of the clinical range — for the first 3–7 days to assess tolerance and individual response. Most people who do not feel the expected effect at the low end need to titrate up to the midpoint (~450 mg) over 1–2 weeks before evaluating whether Alpha-Lipoic Acid works for them. Some users — particularly those with smaller body mass or sensitive baseline neurochemistry — find the low end fully sufficient.

Timing

Recommended timing: AM, empty stomach.

Half-life context: short — same-day clearance, typically 1–3 doses per day.

With or without food

before food: Take 20–30 minutes before a meal for clean absorption. Eating immediately after dosing can blunt peak plasma concentration through competition with food amino acids or by slowing gastric emptying.

Protocol note

R-ALA form is more bioavailable.
