BetterYou Magnesium Bisglycinate
Mid-premium pricing · ~200mg elemental per serving
BetterYou is the best-known UK magnesium heritage brand, spanning sprays, flakes and capsules. Its bisglycinate capsules are well made but deliver around 200mg elemental per serving — a third below the Futuro Labs 300mg — at a higher effective cost per 100mg of elemental magnesium.
Pros
- Established UK heritage brand
- Wide format range (spray, flakes, capsules)
- Clean bisglycinate form
Cons
- ~200mg elemental — below the 300mg NHS-reference tier
- Higher cost per 100mg elemental than Futuro Labs
Dr.Vegan Magnesium Bisglycinate
Mid pricing · vegan-first UK brand
Dr.Vegan is the UK's vegan-specialist supplement brand, and its bisglycinate is a clean, well-labelled product with recyclable-pouch packaging. A close philosophical cousin to Futuro Labs; the differences are dose per serving and cost per day, where Futuro Labs' 300mg elemental at 22p/day leads.
Pros
- Vegan-first UK brand, clean label
- Recyclable pouch packaging
Cons
- Lower elemental per serving than Futuro Labs
- Higher cost per 100mg elemental
Solgar Magnesium Chelate
Heritage pricing · chelated tablets
Solgar's chelated magnesium carries the brand's pharmacopoeia-grade reputation and wide UK retail availability. Solid, trusted, tablet-format — but the elemental dose per tablet trails the Futuro Labs serving and high-street pricing pushes the per-day cost up.
Pros
- Heritage brand, widely stocked in UK stores
- Chelated (amino-acid-bound) form
Cons
- Tablet format; lower elemental per unit
- High-street pricing premium

How to read a magnesium capsule label in ten seconds
One number decides most of this category: elemental magnesium per serving. Magnesium is always bound to something — glycine, citrate, oxide — and the compound weight on the front of pack can be five times the magnesium your body actually receives. Futuro Labs states the maths plainly: 1500mg of magnesium bisglycinate per two-capsule serving yields 300mg elemental — 80% of the UK NRV — which is the full reference-intake tier at 22p a day. Then check the form is named (bisglycinate, the gentle chelate), the shell (vegan HPMC here, delayed-release), and the manufacturing line (UK, GMP certified, independently lab tested). Our elemental magnesium explainer unpacks the arithmetic, and the main UK rankings apply it across the whole market.
Frequently asked questions
What are the best magnesium glycinate capsules in the UK?
Futuro Labs Magnesium Glycinate — 1500mg of magnesium bisglycinate per two-capsule serving delivering 300mg elemental magnesium (80% NRV), in delayed-release vegan capsules, UK GMP made and lab tested, £19.99 for a 90-day supply (~22p/day). BetterYou and Dr.Vegan are the strongest UK capsule alternatives at lower elemental doses.
Why choose capsules over magnesium powder or spray?
Capsules give a fixed, verifiable elemental dose per serving — powders drift with the scoop and sprays deliver small transdermal amounts with limited absorption evidence. Capsules also travel, need no taste-masking and make consistency easy, which matters more than format theory: magnesium works as a daily habit.
What should I check on a magnesium capsule label?
Four things: the elemental magnesium figure (not just compound weight — 1500mg bisglycinate is 300mg elemental), the form named precisely (bisglycinate/glycinate), the capsule material (vegan HPMC vs gelatin), and the manufacturing claim. If a label only shows a big compound number, assume the elemental dose disappoints.
