Magnesium 90 vs 180 Capsules: Which Size Should You Buy?
Same formulation, same daily rate — so the 90 vs 180 decision is honestly just trial versus commitment. The pouch that funds a proper evaluation for £9.99, the bottle that protects the habit, and the rule for choosing.
At a glance
- Same product, same rate: ~22p/day either way
- 90-capsule pouch — £9.99: 45 days · the trial purchase · covers the evaluation window
- 180-capsule bottle — £19.99: 90 days · the habit purchase · no reorder gaps
- Decision rule: first time = pouch · repeat buyer = bottle
One product, two commitments
Futuro Labs sells its magnesium glycinate in two sizes and — unusually for the supplement aisle — prices them at the same daily rate, which strips the decision down to an honest question: how sure are you? Both contain the identical formulation (750mg bisglycinate per delayed-release vegan capsule; two capsules = 1500mg bisglycinate = 300mg elemental, 80% NRV; UK GMP made, lab tested). The 90-capsule pouch at £9.99 runs 45 days. The 180-capsule bottle at £19.99 runs 90. No secret bulk discount, no small-size tax: just trial versus commitment.
The case for starting with the pouch
Magnesium's fair test is four to eight weeks of consistent daily use — the window every guide on this site sets, from sleep quality to everyday stress — and the 45-day pouch covers it exactly, with a margin. £9.99 is the cheapest properly-run magnesium trial on the UK market, the pouch travels and posts through a letterbox, and if the habit doesn't earn its place you've risked a tenner. It is also the sensible vehicle for a gentle-start protocol: one capsule (150mg elemental) daily for the first week stretches it further while your stomach votes.

£9.99 for 45-day supply (90 capsules) · ~22p per day
Available from: Amazon UK — £9.99
The case for the bottle once you're sold
Habits die in the gaps, and the 90-day bottle's real product is continuity: one purchase a quarter, no run-out weekend, no drift while a reorder sits in a basket. At the identical daily rate the bottle isn't a saving — it's insurance for the streak, which for a repletion mineral is the whole mechanism. Most readers' path runs pouch → bottle → quarterly rhythm; the full product breakdown lives in the Futuro Labs magnesium review and the category context in the UK rankings.

The two-bottle habit, priced over a year
Zoom out and the arithmetic gets pleasantly boring. A full year of the 300mg elemental serving is four bottles — £79.96, or 22p a day every day — which prices magnesium's entire annual base layer below a single month of many premium "sleep formulas" and below two months of food-grown alternatives. The pouch route to the same year (eight pouches) also lands at £79.92: identical, by design, so nothing punishes the cautious start. The practical rhythm most readers settle into: one £9.99 pouch to earn the habit its place, then bottles on a quarterly reorder, with the pouch reappearing only as the travel and holiday format.
Frequently asked questions
Should I buy the 90 or 180 capsule Futuro Labs magnesium?
Same product, same 22p/day rate — the choice is commitment. The 180-capsule bottle (£19.99) is 90 days at two capsules daily: the right buy once magnesium is a standing habit. The 90-capsule pouch (£9.99) is 45 days: the right first purchase, covering the full 4-8 week evaluation window with change to spare.
Is the bigger magnesium bottle better value?
Unusually, no — Futuro Labs prices both sizes at the same ~22p per day, so the pouch carries no small-size penalty. The bottle's value is practical rather than financial: fewer reorders, no gap risk mid-habit, and a format that lives on a shelf rather than in a drawer.
How long does a bottle of magnesium glycinate last?
At the standard two-capsule (300mg elemental) daily serving: the 180-count bottle lasts 90 days, the 90-count pouch 45 days. If you split the serving morning and evening it lasts the same; only a deliberate one-capsule (150mg) dose stretches the pouch to 90 days — a reasonable gentle-start protocol for sensitive stomachs.
