Magnesium

Magnesium is defined by variability.

It exists in multiple forms, each with different absorption profiles and functional emphasis.

At a high level, evaluation comes down to three signals:

• Form (glycinate, citrate, oxide, etc.) — differences in bioavailability and use
• Dose vs tolerance — how intake aligns with digestive limits
• Functional context — whether the form matches the intended use

Magnesium is often treated as a single category.
Its forms are not equivalent.

Form determines how it behaves.
Without it, the label lacks resolution.
