Absorption & Bioavailability

When it comes to Magnesium supplementation, form selection is one of the most consequential decisions you can make. Different chemical forms of Magnesium vary significantly in how well your body absorbs and uses them — and as Albion® Magnesium Bisglycinate Chelate Buffered vs Magnesium L-Threonate is one of the most commonly compared pairs.

as Albion® Magnesium Bisglycinate Chelate Buffered and Magnesium L-Threonate share the same absorption profile (good absorption).

as Albion® Magnesium Bisglycinate Chelate Buffered shows good absorption and is classified as Preferred Form in the FormulaForge formulary. Magnesium L-Threonate shows good absorption and is classified as Secondary Form.

Magnesium bisglycinate chelate (Albion TRAACS) delivers up to 4-7x greater absorption than magnesium oxide, the most common supplement form. The chelated glycine carrier uses amino acid transport channels rather than competing for mineral absorption pathways, resulting in significantly less GI distress — a common reason patients discontinue magnesium supplementation.

Dosing Comparison

Because forms with lower bioavailability require a larger amount to deliver equivalent absorbed nutrient, dose ranges should not be compared interchangeably between forms without accounting for these differences. Speak with your healthcare provider to determine the appropriate dose for your goals.

Side Effects & Tolerability

Both as Albion® Magnesium Bisglycinate Chelate Buffered and Magnesium L-Threonate are generally well-tolerated at recommended doses. Always consult a healthcare provider before starting any new supplement, particularly if you have existing health conditions or take medications.
