"It's a 1000 mcg hydroxocobalamin (vitamin B12) lozenge designed for sublingual absorption."
Bottom line:
Consumer advice
If you have confirmed B12 deficiency (via blood test), this is a solid choice—hydroxocobalamin is genuinely more bioavailable than cyanocobalamin. However, before buying through Fullscript, compare the final price to standard B12 lozenges from drugstores (Nature Made, Jarrow, etc.), which are often 50-70% cheaper for equivalent doses. Only choose this if your practitioner specifically recommends hydroxocobalamin and the price is competitive after login. If you don't have confirmed deficiency, don't supplement—excess B12 is excreted in urine and won't help.
