Some magnesium supplements look impressive on the label — especially those claiming large amounts of magnesium from a “complex” of multiple forms.
But when you break down the math, many of these products appear to rely overwhelmingly on magnesium oxide: the cheapest, least absorbable, and often least desirable form for everyday supplementation.
In this episode, Carl Pradelli, CEO and Co-Founder of NatureCity, runs the label math on a popular magnesium complex, explains how these misleading magnesium blends work, why capsule claims often don’t add up, and how to spot label engineering designed to make a product seem higher quality than it really is.
Carl takes you step-by-step through numbers and how he reached the conclusion that a 1,000mg blend with 8 types of magnesium has to be at least 90% magnesium oxide, and could plausibly run as high as 98% or 99%.
You’ll also learn why pure magnesium bisglycinate chelate is often a much better option for supporting magnesium levels without unwanted gastrointestinal effects.

WHAT YOU'LL LEARN
• Why "proprietary blend" and "magnesium complex" labels can hide what you're actually buying
• The capsule math showing why a 1,000mg, 8-form magnesium blend has to be at least 90% magnesium oxide
• How much magnesium most adults actually need, and why 1,000mg a day rarely makes sense without a doctor's guidance
• Why magnesium oxide is poorly absorbed, with some estimates as low as 4%
• What Carl looks for instead: pure magnesium bisglycinate chelate, and why it doesn't fit well in capsules
NatureCity was founded over 20 years ago by Carl and his wife Beth on a commitment to science and ingredient transparency, and has served over 500,000 Americans since. Full chapter breakdown below.
