Absorption by Form
What is Magnesium?
Magnesium is a Mineral supplement available in 8 forms.
Not all forms of Magnesium are equal. The form you choose determines how much Magnesium actually reaches your tissues, and the difference between the best and worst forms can be substantial. 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.

What the Research Shows
Magnesium bisglycinate chelate is one of the most bioavailable forms of magnesium, with research indicating superior absorption compared to magnesium oxide (up to 4-7x difference in bioavailability). The chelated glycine carrier allows absorption through amino acid transport channels, resulting in less GI distress. Albion TRAACS chelate is the gold-standard form used in clinical research, with published studies supporting its use for sleep quality, muscle recovery, and stress response support.
Magnesium amino-acid chelate showed significantly greater absorption than magnesium oxide at 60 days (randomised parallel study, Walker 2003). PMID: 14596323
PMID: 7815675
PMID: 39770988
How to Choose the Right Form
Magnesium (as Albion® Magnesium Bisglycinate Chelate Buffered) is classified as Preferred Form by FormulaForge — our top recommendation for Magnesium. It carries a bioavailability rating of good absorption, meaning more of the active compound reaches your tissues per dose unit compared to lower-rated forms.
When choosing a Magnesium supplement, look for the S1 (best absorption) bioavailability tier on the label. Preferred Forms have the strongest research-backed evidence for efficient absorption.
Other forms may be appropriate depending on individual goals, cost considerations, and your healthcare provider’s guidance. The best form for you depends on your specific health needs.
