How we rank
We rank by cost-per-dose — price ÷ servings, normalized to the daily dose (300 mg/day)— so bottle sizes and strengths compare fairly. Prices are scraped at publication and re-checked when the catalog refreshes (see the “Prices checked” stamp above). There is no paid placement and no kickback for ordering. Full methodology · Editorial standards.
That cost-per-dose number is the one most retailers and review sites leave out — they’ll show a sticker price and a serving size, but not what a day actually costs. We compute it for every product so you can compare like for like.
The cheapest bottle isn’t automatically the best value: a low-absorption form (magnesium oxide is the classic example) can look cheap per milligram yet deliver less of what you actually absorb. Where forms differ, compare cost per absorbed or elemental unit, not the compound weight on the label. A bigger bottle isn’t automatically cheaper per dose either — this list already ranks by cost per dose, so a larger count only wins if it truly costs less per serving. Compare Magnesium Taurate forms.
Our data on this: the big bottle saves a median ~86% per serving · the gummy tax (~2× more) · the form premium · the price spread.
Cost-per-serving normalizes price across bottle sizes — a 60-count and a 365-count compare fairly.
