How they differ in real use
Built from our magnesium glycinate for sleep scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Thorne, Magnesium Bisglycinate, 6.5 oz (187 g) and the Doctor's Best, High Absorption Magnesium Lysinate Glycinate, 100 mg, 240 Tablets made our Top 5 Magnesium Glycinate for Sleep, at #1 (best overall) and #4. Its NSF Certified for Sport listing gives it a decisive advantage on the highest-weighted criterion, while the pure bisglycinate form and transparent 200 mg elemental dose remain strong. The premium price prevents a higher Value score but does not outweigh its certification advantage. It combines a transparent chelated form, excellent active-ingredient value and unusually strong buyer-volume evidence. It ranks below the NOW powder because its 200 mg serving is farther from the 250 mg trial dose and it uses substantially more excipients.
