Doctor's Best High Absorption Magnesium is the budget-friendly answer to "which magnesium form actually absorbs," using a named branded chelate instead of cheap oxide — a solid choice if you're price-sensitive but still want a real bioavailable form.
The form is Albion TRAACS magnesium lysinate glycinate chelate, fully disclosed at 100 mg elemental magnesium per tablet, 200 mg per 2-tablet serving, with no proprietary blend (Doctor's Best).
This is the weak point: no NSF, USP, or Informed certification, and batch COAs aren't consistently published — the brand leans on the Albion raw-material brand's reputation rather than finished-product third-party verification (independent review).
No recalls or lawsuits found. At $18.99-$20.99 for 240 tablets (~$0.28/effective day), it's one of the cheapest ways to buy a branded chelate (Doctor's Best). Compared to Jigsaw Health's MagSRT, you're giving up ConsumerLab verification and posted lab reports for a much lower price.
