The Verdict

Nature Made scores higher on our rubric (95 vs 84 on our 0-100 execution score), driven by its USP Verified certification. NOW Foods is cheaper, at about $0.08 per dose versus Nature Made's $0.13, and adds rose hips. In our view, for a supplement this simple, the choice comes down to whether you value the USP seal enough to pay a couple cents more per dose - Nature Made if yes, NOW Foods if you want the lowest cost from a reputable brand. Both deliver the same effective ascorbic acid.

Why This Comparison Matters

Nature Made and NOW Foods both make a 1000mg vitamin C at a value price, and both use ascorbic acid - the form the body cannot distinguish from food-sourced vitamin C. Nature Made carries USP Verification; NOW Foods adds rose hips and runs GMP-audited manufacturing. This is a clean mainstream ascorbic-acid matchup.

Vitamin C is one of the least complicated supplements: ascorbic acid is ascorbic acid, and the fancy forms rarely justify their premium. So the decision is really about certification and cost.

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.
