Not All Magnesium Is Created Equal: A Guide to Forms & Doses

Magnesium supports sleep, muscle relaxation, and energy production, but absorption and side effects vary widely by form.

Common forms

Glycinate

Often well tolerated and popular for evening use when relaxation and sleep quality are the goal.

Citrate

Can have a mild osmotic effect at higher doses; some people use it deliberately for digestion support.

Threonate

Marketed for cognitive applications; evidence is still evolving compared to more established forms.

Oxide

Inexpensive but poorly absorbed for many people — not our first choice for repletion.

Dosing and timing

Start low, use the form that matches your goal (sleep vs. digestion vs. general intake), and separate magnesium from certain medications per your pharmacist or physician.

We help clients pick forms and doses that match their symptoms and labs instead of buying the cheapest bottle on the shelf.
