Nature Made Vitamin B12 3000mcg Sublingual (40 Lozenges)
by Nature Made
"3000mcg B12 sublingual lozenge for direct bloodstream absorption — the USP Verified B12 with 18,000+ reviews under $12"
Overview
Nature Made Vitamin B12 3000mcg Sublingual provides cyanocobalamin in a cherry-flavored lozenge designed to dissolve under the tongue for direct absorption into the bloodstream, bypassing the digestive system. Sublingual delivery is particularly important for B12 because oral absorption requires intrinsic factor (produced by stomach parietal cells), and many people — especially those over 50, those on PPIs/metformin, and those with pernicious anemia — have impaired intrinsic factor production. The sublingual route bypasses this bottleneck entirely. The 3000mcg dose (125,000% DV) may seem excessive, but B12 has no known toxicity level and excess is simply excreted in urine.
