Why magnesium is a category
Magnesium is the highest-velocity mineral category in UK supplements. Across grocery, pharmacy, and DTC, magnesium is typically a top-three bestseller by unit volume, driven by mass consumer awareness of sleep, stress, and muscle-recovery positioning.
The magnesium opportunity for brand founders isn't 'launch a magnesium product': the category is crowded. It's differentiation on form, format, and positioning: which magnesium salt you use, which format you deliver in, and which claims you support with what evidence.
Forms
Magnesium forms and positioning
Magnesium salts differ in elemental magnesium content, bioavailability, and cost:
- Magnesium glycinate (bisglycinate): chelated form; high bioavailability; soft on the gut; premium positioning. The 'sleep and stress' magnesium.
- Magnesium citrate: mid bioavailability; mild laxative effect at higher doses; flexible format compatibility. The workhorse form for sports hydration.
- Magnesium oxide: highest elemental magnesium by weight; lowest bioavailability; lowest cost. Workhorse for cost-sensitive products.
- Magnesium threonate: premium niche for cognitive positioning; highest cost-per-mg; smaller retail category but growing fast in nootropic space.
- Magnesium malate: common in chronic-fatigue positioning; moderate cost and bioavailability.
- Magnesium taurate: cardiovascular positioning; niche but growing.
Retail positioning usually drives form selection. We'll recommend a magnesium form based on your target consumer, claims positioning, and price-point during NPD.

Magnesium manufacturing FAQs
Common questions from brands developing magnesium products.
Which magnesium form should my product use?
Depends on positioning: glycinate for sleep/stress premium products, citrate for sports and hydration, oxide for cost-sensitive mass products, threonate for cognitive/nootropic products. We recommend during NPD based on your target consumer and retail price point.
What's the MOQ for magnesium products?
1,000 units per SKU across all formats.
What's the typical magnesium dose in a UK supplement?
