The Verdict
NOW Foods edges it on our rubric, 86 to 85 on our 0-100 execution score, and holds our Top Pick badge in the ginseng scorecard. That one-point margin hides how differently the two get there. CheongKwanJang wins purity verification 23 to 20 and transparency 23 to 20, on the strength of Korean regulatory oversight, documented root age, and a disclosed extraction process. NOW wins the whole thing back on value, 21 to 14, because $0.10 a day against $1.52 a day is not a close call.
Both earn a full 25 on dosing and form. In our view NOW Foods is the sensible default: it guarantees ginsenoside content, which is the thing that actually goes missing in cheap ginseng, and it does it for pennies. CheongKwanJang is our Premium Pick and worth the money only if authenticated Korean Red Ginseng specifically is what you are after, since that is the form behind most of the positive trial results.

Why This Comparison Matters
These two sit at opposite ends of the ginseng market, and the gap between them on price is roughly fifteen times. NOW Foods sells a 500mg Panax ginseng root extract standardized to 7% ginsenosides, which works out to 35mg of ginsenosides per capsule and lands inside the range clinical trials have used. Korea Ginseng Corp sells CheongKwanJang in stick packs at an amount equivalent to 3000mg of root per serving.
The reason anyone pays the premium is oversight. Per our notes, Korea Ginseng Corp is a Korean government-regulated brand using six-year-old roots with 293 quality checks per product, and Korean Red Ginseng is the form used in most of the positive clinical trials in this category. NOW Foods runs an NPA GMP audited facility and claims third-party testing. Neither product carries USP or NSF certification, which matters more here than usual because our ginseng profile flags adulteration risk across every unverified product in the category.
On cost, NOW Foods is about $0.10 per day from a 250-count bottle at $25.99, roughly eight months of supply. CheongKwanJang is about $1.52 per day from 30 sticks at $45.49. We scored both on dosing and form, purity verification, value, and label 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.

Per our notes you are paying for Korean government-regulated manufacturing, six-year-old roots, and 293 quality checks per product. Our value pillar scores that 14 against NOW's 21.
Is either ginseng USP or NSF certified?
Neither. NOW Foods is NPA GMP audited and claims third-party testing; Korea Ginseng Corp is Korean FDA regulated and GMP certified. Our ginseng profile notes adulteration risk exists across all unverified ginseng, so standardization on the label is the practical substitute, and both products state theirs.
