Both forms correct B12 deficiency equally well in clinical practice; theoretical advantage is marginal.

Consumer advice
If you have confirmed B12 deficiency (via blood test), this product is legitimate and will work. However, before buying, compare the price to standard B12 lozenges at drugstores (often $5–15 for similar doses). Hydroxocobalamin is a good form, but cyanocobalamin (the standard form) works just as well for most people at a fraction of the cost. Don't buy through Fullscript's practitioner model unless your healthcare provider specifically recommends it—you're likely paying a markup for convenience and professional curation rather than superior efficacy.
