Our view, stated clearly.
We favor magnesium bisglycinate as a clearly named chelated form commonly chosen when gastrointestinal tolerance matters. OsteoMagnesium then makes the choice measurable by disclosing 50 mg of elemental magnesium per capsule within its coordinated mineral formula.
Why magnesium is foundational
Magnesium is a cofactor in more than 300 enzyme systems. It contributes to energy production, normal muscle and nerve function, protein synthesis, blood glucose control, and the structural development of bone.1
That breadth is exactly why we resist turning magnesium into a single-benefit ingredient. It is mineral infrastructure: useful because many normal systems depend on it.
Why choose the bisglycinate form?
Magnesium bisglycinate binds magnesium to glycine. We value the form because it gives the formula a defined chemical identity and is commonly chosen when gastrointestinal tolerance matters.2
Bisglycinate gives formulators a clearly defined chelated form and is commonly selected when gastrointestinal tolerance matters. Product quality still depends on elemental amount, tolerability, and fit within the complete formula.
What does the label number mean?
Supplement Facts panels declare elemental magnesium—not the total weight of the magnesium-bisglycinate compound. OsteoMagnesium provides 50 mg elemental magnesium per capsule, or 12% of the Daily Value.2
The 50 mg amount is a defined contribution inside a four-ingredient system with D3, K2, and PQQ. A sleep trial using 250 mg elemental magnesium provides useful research context for that different amount and intended outcome.
Magnesium bisglycinate earns our preference as a purposeful, named chelate. OsteoMagnesium discloses 50 mg elemental magnesium as a defined contribution to its D3 + K2 + magnesium + PQQ system.
What earns our confidence
Named source
The panel should say magnesium bisglycinate, not merely “magnesium complex.”
Elemental amount
Compare the magnesium line in milligrams per complete serving.
Realistic role
A supportive formula dose is different from repletion under medical supervision.
Tolerance context
Supplemental magnesium can cause diarrhea; individual tolerance and total intake matter.
Magnesium Bisglycinate FAQs
Is magnesium bisglycinate the same as elemental magnesium?+
No. Bisglycinate is the compound; only part of its weight is magnesium. Supplement Facts should state the elemental magnesium provided.
Is bisglycinate the best magnesium form?+
We consider it a strong, purposeful form, especially when tolerability matters. Elemental amount and the complete formula determine how that form choice translates into a product.
Why does OsteoMagnesium provide 50 mg?+
It provides 12% of the Daily Value as a complementary mineral contribution within a D3 + K2 + magnesium + PQQ system, rather than using magnesium as the formula's only active strategy.
Can magnesium interact with medicines?+
Yes. Magnesium can affect absorption of medicines such as some antibiotics and bisphosphonates. Ask a healthcare professional about timing and suitability.
