Hydroxy B12 (AOR) Review 2026: Worth the Price?
Checks out. — Mostly Legit
-
"Hydroxocobalamin converts better to active B12 forms than cyanocobalamin"
This is accurate. Hydroxocobalamin feeds both methylcobalamin and adenosylcobalamin pathways; cyanocobalamin requires extra conversion steps.
-
"1000mcg dose is therapeutically meaningful"
1000mcg sublingual hydroxocobalamin is the standard clinical dose for B12 deficiency correction. Dose is fully transparent and appropriate.
-
"Price transparency"
No price is shown without creating a practitioner account. Comparable hydroxocobalamin lozenges retail for $10–15 for 60 count elsewhere.
Consumer advice
If you've been told by a doctor or dietitian that you need B12 supplementation, hydroxocobalamin is a solid form to use — it's well-absorbed sublingually and converts efficiently to active coenzyme forms. You don't need to buy it through Fullscript, though. Jarrow Formulas, Source Naturals, and NOW Foods all make hydroxocobalamin or methylcobalamin lozenges at similar doses for $10–15 at retail. If your practitioner recommends this specific AOR product, that's fine — but shop around first since the price here is opaque. One practical note: if you're not actually B12 deficient, supplementing won't give you an energy boost. Get your levels tested before spending money on this.
