Quick answer

Acetyl l carnitine for nerve pain has been tested in four trials with 907 people, at 1,500 to 3,000 mg a day. A Cochrane review rated the evidence very low certainty. SciatiEase lists 250 mg of acetyl-L-carnitine per 4 capsules, far under those doses.

The review01

What does the evidence say about acetyl l carnitine for nerve pain?

Acetyl l carnitine for nerve pain has very low certainty evidence behind it. A Cochrane review pooled four trials with 907 people.

Pain fell more than with placebo overall, but there was little difference at 1,500 mg a day or less (Cochrane, Acetyl-L-carnitine 2019).

The Cochrane review
Trials and people	4 trials, 907 people
Doses studied	1,500 to 3,000 mg a day
Certainty	Very low

The caveats02

Why do reviewers doubt the results?

Reviewers doubt the results because the trials were few, small and partly maker-funded. Two trials were paid for by a carnitine manufacturer. Two had a co-author who consulted for one (Cochrane, Acetyl-L-carnitine 2019).

FAQ05

Carnitine questions

What is the difference between L-carnitine and acetyl-L-carnitine?

Acetyl-L-carnitine is carnitine with an added acetyl group. Studies of nerve pain used the acetyl form, which is what the SciatiEase panel lists at 250 mg per 4 capsules.

Why does a Cochrane rating of very low certainty matter?

It means the true effect could be quite different from the study results, so any benefit is unconfirmed until larger, independent trials report.

Does the lowest trial dose compare with 4 SciatiEase capsules?

No. The lowest studied dose was 1,500 mg a day, while four SciatiEase capsules hold 250 mg.
