Direct answer
No. Beta-2 Microglobulin is not an approved medicine in Canada; its classification is "Research use only; not approved". Nothing containing it is authorized for any use in people. Vials labeled "for research use only" are not exempt: that label does not make human use lawful. On the evidence, 1 human study is cited on its profile.

What this means
- 01
No product containing Beta-2 Microglobulin is approved by Health Canada for any use in Canada, so nothing on the market is authorized for people.
- 02
"Research use only" is a vendor label, not a legal category that permits human use. It does not exempt a product from medicines law.
- 03
Importing, supplying or promoting it for human use can fall under medicines legislation in Canada. This page is general information, not legal advice.
What Beta-2 Microglobulin is
A blood protein that rises with age and impairs neurogenesis and memory when injected into young mice. In people it is a long-established clinical analyte and is associated with worse cognition; nobody has tried lowering it for ageing.
Beta-2 microglobulin is the light chain of MHC class I molecules and is present in everyone's blood. A 2015 Nature Medicine paper identified it as a circulating pro-ageing factor: B2M is elevated in the blood of ageing humans and mice and in the hippocampus of aged mice and young heterochronic parabionts.
Mechanism: In mice, systemic or intrahippocampal B2M impairs hippocampal-dependent cognition and neurogenesis, effects partly mitigated by reducing cell-surface MHC class I. The 2023 molecular work identifies B2M as an endogenous NMDA receptor antagonist acting through the GluN1-S2 loop, with competitive peptides restoring receptor-dependent synaptic function.
Regulatory history: No B2M-lowering therapy is approved for ageing or cognition and none is in a registered trial for those uses. B2M is measured clinically as a laboratory analyte in renal and haematological medicine.
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Beta-2 Microglobulin 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.

Is Beta-2 Microglobulin Health Canada approved?
No. In Canada Beta-2 Microglobulin is classified as "Research use only; not approved", which is not a Health Canada marketing approval. For comparison, the US FDA status is: No B2M-lowering therapy is approved for ageing or cognition and none is in a registered trial for those uses.
