The Verdict
Doctor's Best (A- overall) edges out NOW Foods (B+ overall) with a slight quality advantage from the Albion TRAACS chelate. But NOW Foods costs just $0.09/day vs $0.13/day - making it the better pure-value play. Both are strong options. If the Albion chelation research matters to you, Doctor's Best is worth the extra four cents per day. If you want the absolute cheapest quality glycinate, NOW Foods delivers.

Why This Comparison Matters
Doctor's Best and NOW Foods both target the value-conscious buyer who wants chelated magnesium without paying practitioner-grade prices. Both are among Amazon's best-selling magnesium products, and both frequently appear in "best magnesium" recommendation lists.
The key difference is in the chelation technology. Doctor's Best uses Albion TRAACS - a patented mineral chelation process with published bioavailability data. NOW Foods uses a standard glycinate chelate. Whether that difference matters depends on how much you trust the Albion research and whether you are willing to pay a small premium for it.
We scored both products across evidence, quality, value, and transparency to give you a clear picture.

How We Compared These Products
Every product in our database is scored on four equally-weighted categories: clinical evidence quality, third-party testing and purity verification, cost per clinically effective dose (not cost per pill), and label transparency. These scores combine into an overall letter grade from A+ through F.
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.
