Is Oxaloacetate legal in the United Kingdom?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Oxaloacetate can be sold in the United Kingdom as a supplement or cosmetic ingredient, classified as "Sold as a supplement". That is not drug approval: MHRA has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 2 human studies are cited on its profile.

What this means
- 01
Oxaloacetate can be sold in the United Kingdom as a supplement, food or cosmetic ingredient under the classification above, without drug approval.
- 02
Supplement status means MHRA has not evaluated any health claim; manufacturers are responsible for safety and labeling, and quality varies by product.
- 03
Injectable or "research use only" versions are not supplements. That label does not make human use lawful, and injectables fall under medicines rules.
What Oxaloacetate is
No lifespan effect in either sex when fed to mice from 4 months of age. The human record is two small trials: 82 people with chronic fatigue syndrome and 30 people with Alzheimer's disease, neither measuring an ageing outcome.
Oxaloacetate is a four-carbon intermediate of the citric acid cycle, sold as a stabilised anhydrous salt because the free acid degrades quickly. The longevity interest came from worm work, where supplementation extended Caenorhabditis elegans lifespan, apparently through AMP-activated protein kinase and the FOXO transcription factor, and from the idea that raising the cytosolic NAD to NADH ratio mimics some of calorie restriction's signalling.
Mechanism: A citric acid cycle intermediate that condenses with acetyl-CoA to form citrate, and the direct product of malate oxidation by malate dehydrogenase. Supplemental oxaloacetate is proposed to shift the cytosolic NAD to NADH ratio by driving the malate-aspartate shuttle, which is the mechanistic overlap claimed with calorie restriction and with NAD precursors.
Regulatory history: Sold as a dietary supplement. Not an approved drug and not approved to prevent or treat anything.
How MHRA treats this kind of product
Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency listings for Oxaloacetate at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
