Does Alpha-Lipoic Acid build up with daily dosing?

Hardly at all in the model. With a half-life of about 30 minutes, a daily interval is 5 or more half-lives, so each dose has almost fully cleared before the next one and every dose draws about the same curve. The level is near zero for much of each interval.

Is this chart my actual Alpha-Lipoic Acid level?

No. It is a modeled estimate from a published half-life, using the same one-compartment model as the Dose Track app. Real levels vary with body weight, food, kidney and liver function and other factors, and only a lab test measures them. It is not medical advice.

Alpha-Lipoic Acid Half-Life: Peak and Steady State Chart

Q: When does Alpha-Lipoic Acid peak after a dose?

Blood levels peak about 30 minutes after a dose by mouth, according to Breithaupt-Grögler K et al. 1999. Individual timing varies with food, the amount and the person.

Q: How long does Alpha-Lipoic Acid take to reach steady state?

About 2.5 hours of regular dosing at the same amount and interval, which is 5 half-lives. With a half-life of about 30 minutes, levels reach about 50% of steady state after 30 minutes and about 90% after 1.7 hours. Changing the dose or interval starts a new climb toward a new steady state.

Q: How long does Alpha-Lipoic Acid stay in your system after the last dose?

Roughly 5 half-lives, about 2.5 hours, until about 97% has cleared in the model. Half is gone about 30 minutes after levels start falling. Real clearance varies from person to person, and a drug can still have effects after levels are low.

Short answer: Alpha-Lipoic Acid has a half-life of about 30 minutes (Breithaupt-Grögler K et al. 1999) and reaches steady state after about 2.5 hours of regular dosing. Levels peak about 30 minutes after a dose by mouth. With daily dosing it clears almost completely between doses, so levels do not build up.

What do Alpha-Lipoic Acid levels look like with daily dosing?

Relative units: 1 on the scale is one full dose. There is no FDA label dose for this use, so the chart shows the shape of the curve, not an amount. Dashed line: 5 half-lives. Change the amount or schedule in the calculator.

When does Alpha-Lipoic Acid peak after a dose?

Levels peak about 30 minutes after a dose by mouth.

How long does Alpha-Lipoic Acid take to reach steady state?

With regular dosing at a fixed amount and interval, levels climb toward steady state by the same fraction every half-life, whatever the dose. At a half-life of about 30 minutes:

Time from the first dose to each share of steady state, Alpha-Lipoic Acid (half-life 30 minutes).
Share of steady state	Half-lives	Time
50%	1	30 minutes
75%	2	1 hour
90%	3.3	1.7 hours
97% (Dose Track's steady-state rule)	5	2.5 hours

How much do Alpha-Lipoic Acid levels swing between doses?

The longer the gap between doses compared with the half-life, the bigger the swing from peak to trough and the less the levels build up. These ratios do not depend on the amount.

Steady-state peak:trough and build-up by dosing interval, Alpha-Lipoic Acid, in Dose Track's model.
Interval	Peak : trough	Build-up vs one dose
Daily	over 1,000 : 1	1×
Every other day	over 1,000 : 1	1×
Twice weekly	over 1,000 : 1	1×
Weekly	over 1,000 : 1	1×
Every 2 weeks	over 1,000 : 1	1×

Build-up is the accumulation ratio 1 / (1 − e^−k·τ), with k = ln 2 / half-life and τ the interval.

How long does Alpha-Lipoic Acid stay in your system?

After the last dose, about half is gone every 30 minutes. After 5 half-lives, about 2.5 hours, roughly 97% has cleared in the model.

Where do these numbers come from?

In healthy volunteers given 50 to 600 mg by mouth (Breithaupt-Grögler 1999), alpha-lipoic acid peaked 30 minutes to 1 hour after a dose and fell with a half-life of about 30 minutes. Another study (Teichert 1998) measured 25 to 33 minutes, and a third reported median peaks at 20 to 30 minutes after 600 mg (Hermann 2014). Dose Track uses 30 minutes for both.

The curve uses the half-life, time to peak, route and bioavailability built into the Dose Track app for Alpha-Lipoic Acid, and the same one-compartment model with first-order absorption. These are modeled estimates from published half-lives, drawn with the same one-compartment model as the Dose Track app. Real levels vary from person to person, and only a lab test measures them. This is not medical advice and not a dosing recommendation; dosing decisions belong with you and your prescriber.
