Clear answers,
carefully bounded.
We use primary sources where possible, link every article to its references, and distinguish the product label from broader educational context.
Magnesium
Elemental magnesium vs. magnesium glycinate: two numbers, one serving
Why a label can state 2,500 mg of magnesium glycinate while declaring 275 mg of magnesium—and why the smaller number is the one used for Daily Value.
Creatine
Creatine, plainly: dose, loading, and consistency
What a 5 g serving means, why loading protocols exist, and how a gradual daily approach differs.
Transparency
What a certificate of analysis can—and cannot—tell you
A COA can be useful evidence, but only after you identify the product, batch, test scope, laboratory, and date it actually covers.
A useful boundary
Education, not a diagnosis.
