Built from our magnesium glycinate for sleep scoring, each product's published specifications, and verified owner feedback — not hands-on testing.

Both the Doctor's Best, High Absorption Magnesium Lysinate Glycinate, 100 mg, 240 Tablets and the NOW Foods, Magnesium Glycinate, 100 mg, 180 Tablets made our Top 5 Magnesium Glycinate for Sleep, at #4 and #5. 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. It matches Doctor's Best on elemental dose and has similarly strong recent sales, but costs more per active amount and uses a longer excipient list. With no stronger third-party verification to offset those disadvantages, it ranks fifth.
