The Verdict
Nature Made scores higher on our rubric (91 vs 85 on our 0-100 execution score), driven by its USP Verified certification. On cost the two are very close - both land near $0.05-$0.07 per dose - so price is not a deciding factor. NOW Foods' edge is its sublingual lozenge format and GMP-audited testing. In our view, if you want the strongest independent verification, Nature Made's USP seal wins; if you prefer a sublingual format, NOW Foods is a fine, inexpensive choice. Both use effective cyanocobalamin.

Why This Comparison Matters
NOW Foods and Nature Made both make a 1000mcg cyanocobalamin B12 at a value price, so this is a clean mainstream matchup. Nature Made is a USP Verified tablet; NOW Foods is a sublingual lozenge with NPA GMP-audited manufacturing. Both use cyanocobalamin, the stable, well-studied form.
For most people cyanocobalamin is perfectly effective - the body converts it to active forms. The sublingual format of NOW Foods can help people who prefer under-the-tongue delivery, though swallowed tablets work fine for the vast majority.
We scored both on evidence, quality, cost per dose, and transparency.

How We Compared These Products
Every product in our database is scored on four equally-weighted pillars: dosing accuracy and form quality, purity verification (third-party testing), cost per clinically effective dose (not cost per pill), and label transparency. Each pillar is worth 25 points for a total of 100.
Cost per effective dose is calculated using the clinically studied dose from published research, not the manufacturer's suggested serving. If a product requires multiple servings to reach the dose used in clinical trials, that cost is reflected in the value score.
