Magnesium glycinate is a form of magnesium bonded to glycine, an amino acid. It's one of several magnesium compounds used in both oral supplements and topical formulations — and the differences between forms matter more than most product labels suggest.
Quick Answer
- Magnesium glycinate is magnesium bonded to glycine, an amino acid — creating a chelated, more stable form than free ionic magnesium
- The glycinate bond improves skin compatibility, reduces irritation, and integrates more consistently into liposomal delivery systems
- Glycine itself is a skin-conditioning amino acid that supports collagen synthesis — both components do useful work at the skin level
- Most mass-market magnesium creams use magnesium chloride; glycinate is a deliberate upgrade for serious topical formulations
What Makes Magnesium Glycinate Different
Magnesium doesn't exist in a vacuum — in every supplement or cream, it's bound to something, and that bond determines how it behaves chemically, how stable it is, and how well it integrates into a delivery system. Common magnesium compounds include:
- Magnesium chloride — widely used in topical sprays and oils; dissolves easily but exists as a free ionic form
- Magnesium sulfate — the active compound in Epsom salts; used primarily in bath soaks
- Magnesium oxide — common in cheap oral supplements; poorly absorbed
- Magnesium citrate — popular oral form; reasonably absorbed
- Magnesium glycinate — magnesium bonded to glycine; one of the gentler, more stable forms for both oral and topical use
What "Self-Chelating" Means
Chelation refers to a molecule being bound within a ring-like structure formed by another molecule. In magnesium glycinate, glycine wraps around the magnesium ion, stabilizing it. This matters for topical use for three reasons:
- Stability — a chelated form is more chemically stable in a cream than a free ionic form like chloride
- Skin compatibility — free magnesium ions can mildly irritate skin at high concentrations; the glycinate bond creates a gentler interaction with the stratum corneum
- Liposomal integration — the structured molecular form of self-chelating glycinate works more consistently with liposome architecture than a loose ionic compound
The Role of Glycine
Glycine isn't just a binding agent — it's a functional ingredient in its own right. It's the smallest amino acid, naturally present in the skin, and classified as a skin-conditioning agent recognized for its role in collagen synthesis. In a magnesium glycinate formulation, both components — the magnesium and the glycine — are doing useful work at the skin level.
Why Form Matters More Than Labels Suggest
Many magnesium creams list "magnesium chloride" as the active ingredient. Chloride is inexpensive and dissolves easily — practical for mass-market formulations. But for a cream designed for deeper absorption, the form of magnesium is a meaningful formulation decision. Self-chelating glycinate offers better stability in a complex cream base, gentler interaction with skin tissue, and more consistent integration into a liposomal delivery system.
How Aftology Uses Magnesium Glycinate
Aftology Magnesium Cream uses self-chelating magnesium glycinate at high levels, carried in a liposomal system, in a plant-derived base. The choice of glycinate over chloride was a deliberate formulation decision reflecting decades of experience in natural skincare. No phenoxyethanol. No synthetic preservatives. Made in the USA.

Frequently Asked Questions
What is magnesium glycinate used for in a cream?
Magnesium glycinate is used in topical creams as a more stable, skin-compatible form of magnesium. The glycinate bond reduces irritation compared to free ionic forms like magnesium chloride, and integrates more effectively into liposomal delivery systems designed to carry magnesium through the skin barrier.
Is magnesium glycinate better than magnesium chloride for skin?
For topical use in a serious formulation, yes. Magnesium glycinate is more chemically stable in a cream base, gentler on skin tissue, and works more consistently with liposomal delivery architecture. Magnesium chloride is cheaper and more common, but it's a free ionic form that can be mildly irritating at high concentrations.
What does glycine do in a magnesium cream?
Glycine serves two roles: it bonds to magnesium to create a stable chelated form, and it acts as a skin-conditioning agent in its own right. Glycine is naturally present in skin and supports collagen synthesis, meaning both components of magnesium glycinate contribute to the formulation's effectiveness at the skin level.
