Our verdict
Doctor's Best High Absorption Magnesium supplies 200 mg of elemental magnesium from 2,000 mg of Albion TRAACS magnesium lysinate glycinate chelate per two tablets. At $13.99 for 120 tablets from Vitacost it costs about $0.12 per 100 mg. We include it because shoppers meet it beside glycinate products, but the chelate uses lysine as well as glycine, so it isn't chemically identical to a bisglycinate-only product. The label's two tablets twice daily reaches 400 mg, above the 350 mg upper limit.
Best for: Value shoppers comfortable with a mixed chelate who take one serving a day.

Dose, formula and the elemental magnesium calculation
The label lists 200 mg of elemental magnesium from 2,000 mg of magnesium lysinate glycinate chelate per two-tablet serving, with 60 servings in a 120-tablet bottle. Other ingredients include microcrystalline cellulose, croscarmellose sodium, magnesium stearate, stearic acid, hypromellose and hydroxypropyl cellulose.
The directions say two tablets twice daily, or 400 mg. That is above the 350 mg adult upper limit for supplemental magnesium, so one serving a day is the conservative choice unless a clinician says otherwise.
Testing and manufacturing: what has actually been verified?
Doctor's Best uses a branded Albion chelate and describes GMP manufacturing. We didn't find product-specific or lot-specific test results for this item.
That places it on tier 3 of our evidence ladder. An ingredient supplier's reputation isn't the same as finished-product testing.
Evidence tiers: tier 1 is publicly verifiable, product-specific evidence; tier 2 is product-specific evidence our editors verified privately; tier 3 is manufacturer-level information without finished-product results; tier 4 is unverified. Full definitions.
Price and value: the fair way to compare
| Option | Price | Per serving | Per 100 mg |
|---|---|---|---|
| One-time, 120 tablets | $13.99 | $0.23 | $0.12 |
Doctor's Best's site blocked our price check, so we used Vitacost's one-time price. Prices for this item vary widely across retailers. We compare one-time prices on the same date across brands, never a sale price against another brand's list price. Cost per 100 mg is a comparison tool, not a dose recommendation.

Customer reviews, reputation and support
We didn't capture a brand or retailer review sample for this product on our check date, so review evidence carries no weight yet.
We weigh verified-purchase feedback, sample size, review dates and repeated complaints such as tablet size, stomach upset or shipping delays. We don't treat self-reported sleep changes or a five-star average as clinical evidence.
Claims check
Doctor's Best markets this chelate as gentle on the stomach and highly absorbable. Chelated forms are generally well tolerated, but marketing comparisons such as "times more absorbable than oxide" need a human study of the exact product to back them.
