BetterYou Magnesium Review: The Heritage Brand, Audited

BetterYou magnesium review — honest UK verdict

The UK's best-known magnesium name, reviewed on the same tests as everything else on this site: form, label honesty, elemental dose, value. A good product paying brand rent — here's the fair audit and where it lands in the field.

At a glance

The brand, fairly introduced

BetterYou is what a UK supplement heritage brand looks like: Yorkshire-based, pharmacy-shelved nationwide, and famous first for sprays — the transdermal magnesium oils that built the company and the oral vitamin D spray that became a winter staple. That history matters to this review in both directions. It buys real trust: BetterYou publishes sourcing stories, runs recognisable UK operations, and has spent two decades accountable to British retail. And it shapes the range: the spray DNA runs through everything, including a magnesium line spanning oils, flakes and — the product this review centres on — bisglycinate capsules, since capsules are where repletion arithmetic actually lives (the transdermal verdict covers why).

BETTERYOU

BetterYou Magnesium Bisglycinate

★ 4/5

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 tier
  • Higher cost per 100mg elemental than Futuro Labs

Run the cluster's usual audit. Form: pure bisglycinate — the right call, gentle and evening-suited, no buffering games. Label honesty: solid; elemental content is findable rather than buried. Dose: the honest caveat — servings deliver around 200mg elemental, a third below the 300mg (80% NRV) tier this site treats as the full daily serving, which matters most for the low-intake readers with the biggest gap to close. Value: heritage pricing puts the cost per 100mg elemental meaningfully above the ~7p benchmark (the value maths). Nothing here is a flaw of quality — it is the ordinary premium of a famous name at a smaller dose.

Where it lands in the UK field

The fair summary: BetterYou bisglycinate is a good product you pay brand rent on. Choose it when high-street availability, the heritage reassurance or the wider BetterYou ecosystem (the vitamin D spray pairing is genuinely convenient) decide for you. Choose the benchmark when arithmetic does: Futuro Labs Magnesium Glycinate delivers the full 300mg elemental per two-capsule serving — 1500mg pure bisglycinate, stated both ways — in delayed-release vegan capsules, UK GMP made and lab tested, at £19.99 for 90 days (~22p/day, ~7p per 100mg elemental), with the £9.99 pouch as the trial format. Full field context: the UK rankings, where both brands hold the positions this review just explained.

Frequently asked questions

Is BetterYou magnesium any good?

Yes — BetterYou is the UK's best-known magnesium heritage brand and its bisglycinate capsules are a clean, well-made product from a company with real UK presence and pedigree. The honest caveats are dose and value: servings deliver around 200mg elemental — below the 300mg tier — at a higher cost per 100mg of elemental magnesium than the category benchmark. Good brand, fair product, beatable arithmetic.

What is BetterYou best known for?

Sprays. BetterYou built its name on transdermal magnesium oils and oral vitamin sprays (its vitamin D spray is a UK pharmacy staple), and the spray heritage shapes the range today. For sprays-as-ritual that pedigree is genuine; for magnesium repletion specifically, this site's position is unchanged — oral capsules with a stated elemental dose are the tool, whoever makes the spray.

BetterYou or Futuro Labs magnesium — which should I buy?

For maximum elemental dose per pound: Futuro Labs — 300mg elemental per serving at ~22p/day versus BetterYou's ~200mg at a higher rate. For heritage-brand reassurance and high-street availability, BetterYou earns its premium honestly. Same form (bisglycinate), same daily-use case; the difference is arithmetic and where you like to shop.

Buying on arithmetic instead of heritage?

Futuro Labs Magnesium Glycinate — 300mg elemental, ~22p/day. £19.99 for 90 days.
