Read the source precision
Eternal Elixir describes its 144 mg elemental figure as approximate. Switch Nutrition states 144 mg in a nutrition panel. The table marks that distinction.
FORM / 03 / CHECKED 22 OCTOBER 2026
Threonate needs two numbers.
Two single-form threonate products describe a 2,000 mg compound serve and around 144 mg elemental magnesium. A third listing is a multi-form blend containing threonate, whose stated elemental total covers all its forms.
BEFORE YOU COMPARE
Different formats
Eternal Elixir uses a three-capsule comparison unit. Switch Nutrition uses 2 g powder. Both selected packs contain 30 stated comparison serves. ATP MagX4 is a blend and its 150 mg total is not a threonate-only amount.
No brain or sleep claim
A compound name or product marketing statement is not evidence that a product improves cognition or sleep. The evidence pages examine research separately.

Blue marks the lowest unrounded cost in this view, not a health recommendation. Bars use a 500 mg display scale, not an intake target. “≈” carries the brand’s approximate elemental amount into the calculated cost. Prices may change.
Two single-form listings and one verified blend are shown. This is a selected comparison, not a market-wide survey.
