Because ours is the truth. Other brands print huge elemental numbers like "400mg" or "500mg" on their bottles, but the only way they can hit those numbers is by mixing in cheap magnesium oxide. We use pure magnesium glycinate, which your body absorbs at 40-50%. Oxide only absorbs at around 4%. Our 338mg of real elemental magnesium (from a full 2,600mg of pure glycinate) puts way more usable magnesium into your bloodstream than their "500mg" of mostly-oxide ever will.

"Buffered" is the polite word brands use when they're cutting their magnesium glycinate with cheap magnesium oxide. They love it because oxide is 63% elemental magnesium by weight, so a tiny bit lets them print a much bigger number on the front of the bottle. The problem: your body can barely absorb oxide. So you're paying for premium glycinate and getting watered-down oxide that goes straight through you. If you see the word "buffered" on a magnesium bottle, that's the giveaway. Run.

Pure magnesium glycinate is only about 13% elemental magnesium by weight. That's a hard chemistry limit. So if a brand claims 400mg of elemental magnesium from 1000mg of glycinate, the maths doesn't add up: 1000mg × 13% = 130mg, not 400mg. We even asked the UK's biggest magnesium supplier about it. He confirmed it's physically impossible to get elemental magnesium levels above roughly 14% from any glycinate. The only way to hit the bigger numbers is to secretly blend in oxide. Which is exactly what's happening across the shelf.

It's a race to the bottom on Amazon. To rank near the top, brands need to be cheap. After Amazon's 30% fee, 20% in tax, ingredients, packaging, shipping and ad spend, there's almost no margin left at £9.99 a bottle. So they cut corners on the one thing customers can't easily check: what's actually inside the capsule. And here's the wild part: nobody checks. Not the government. Not Amazon. Not Trading Standards. There is no routine independent testing of supplements on the UK market. Brands rely on that. That's why we're publishing every single batch test ourselves.

Two ways. First: every single batch is tested by an independent ISO-accredited lab before it ships. Not once a year. Not "per formula". Every batch. Second: every batch test is published online. The batch code on your bottle links to the exact test for the magnesium inside your bottle. You can pull it up on your phone right now. No other UK magnesium brand does this.

They're all "magnesium" but they're not equal. Glycinate is the gentlest and best-absorbed form (40-50%) and the one most people want for sleep, stress and recovery. Citrate (about 16% elemental) is decent but can cause loose stools at higher doses. Malate (about 15%) is similar. Oxide (63% elemental) looks great on a label but absorbs at around 4% and is mostly used as a laxative in higher doses. We only use glycinate because it's the form your body actually wants.

Magnesium runs hundreds of processes in your body, from sleep to muscle function to heart rhythm to mood regulation. Studies suggest around 60% of adults in Western countries don't get enough of it, mostly because the foods richest in magnesium (leafy greens, beans, seeds, nuts) are foods most people don't eat enough of. Low magnesium has been linked to poor sleep, cramps, palpitations, anxiety, headaches and energy crashes. Topping up with a properly absorbed form is one of the simplest things you can do for how you feel day to day.

Take 4 capsules about 30 minutes before bed for a total of 2,600mg of pure magnesium glycinate, delivering 338mg of real elemental magnesium. Glycinate is the calming form, so most people prefer it at night. If you train hard or get muscle cramps, you can also split your serving across the day, for example 2 capsules with lunch and 2 before bed. Either works.

This is exactly why we only use glycinate. Forms like oxide, citrate and malate can pull water into your gut and send you running to the bathroom (which is why oxide is sometimes sold as a laxative). Glycinate is bound to the amino acid glycine, which makes it gentle and easy on digestion. The vast majority of people have zero stomach issues with it, even on an empty stomach.

Most people notice deeper, calmer sleep within the first week. If you've been low on magnesium for a long time (which most UK adults are), the bigger benefits like steadier energy, fewer cramps, less muscle tension and a calmer baseline mood usually show up between weeks 2 and 4 of taking it consistently.

Right here in the UK, at our own GMP-certified facility in Kidlington, just outside Oxford. We make it ourselves. We don't outsource the blending or encapsulation to a contract manufacturer. Same people, same building, same machines, every batch. That's how we're able to test every batch and stand behind what's in the bottle.

You're covered by our 60-day money-back guarantee. Try it for two months. If you don't feel a difference, email us and we'll refund you. No awkward forms, no return shipping, no fight. We'd rather lose a sale than have an unhappy customer.
