Magnesium Multi

Four kinds of magnesium, one mineral the modern diet keeps losing.

Magnesium is the fourth most abundant mineral in the human body, behind only calcium, sodium, and potassium. About sixty percent of the magnesium you carry sits inside your bones; the rest is in muscle tissue, soft tissue, and a small but critical pool in the blood and cells. Magnesium contributes to normal energy-yielding metabolism, normal protein synthesis, normal muscle function and normal functioning of the nervous system. Without enough magnesium, the body cannot do its ordinary daily work cleanly.

The official recommended intake for a UK adult is around 300 milligrams a day for men, 270mg for women. The UK reference intake is 300 mg a day for men and 270 mg for women.

There are three reasons. The first is the soil.

The second is the diet. Magnesium is concentrated in dark leafy greens, whole grains, beans, nuts, and seeds — exactly the foods that have been displaced over the last fifty years by white bread, refined cereals, takeaway dinners, and processed food. The shopping basket has shifted away from the magnesium-rich aisle.

The third is modern stress. Coffee, alcohol, and certain medications (proton pump inhibitors, some diuretics) accelerate the loss further.

The shortfall is not a diagnosis. It is a slow background drift.

A clean cream pot, the green band of our label running around it. One hundred vegan capsules inside — fifty servings: 50 days at one serving a day, 12 days at four. The capsules are HPMC, plant-derived, suitable for vegetarian, vegan, kosher and halal kitchens.

Inside each two-capsule serving: 498 milligrams of elemental magnesium — that's 132% of the daily nutrient reference value — drawn from four different magnesium compounds, alongside 50mg of vitamin C, 110mg of sugar beet fibre, citrus bioflavonoids, apple cider vinegar powder, and a small dose of fructo-oligosaccharides for the gut. The capsule shell itself contributes 240mg of plant fibre.

Two capsules, one serving, taken with water on an empty stomach. The dosing range is one to four servings a day depending on your needs. Most people sit at one or two.

This is the thinking that earned this bottle its name.

Most magnesium supplements on the shelf are a single form — usually magnesium citrate, sometimes magnesium glycinate, sometimes the cheaper magnesium oxide. Each form has a different profile: a different absorption rate, a different effect on the bowel, a different texture in the body. There is no single magnesium form that wins on every metric. They are different tools for different aspects of the same job.

This bottle uses four forms in a deliberate blend.

Magnesium oxide. The densest form by elemental weight — about 60% pure magnesium by mass, more than any other compound. The trade-off is lower absorption per gram in the upper gut. Magnesium oxide is dense in magnesium; at higher amounts it can loosen stools.

Magnesium hydroxide. Closely related to oxide, slightly more soluble, also high in elemental magnesium. The classic form used in milk-of-magnesia preparations.

Magnesium citrate: magnesium bound to citric acid.

Magnesium sulphate heptahydrate (Epsom salt): highly water-soluble.

The label warns plainly that 450mg of magnesium may cause mild stomach upset in sensitive individuals. This is honest. Magnesium oxide in particular can have a laxative effect at higher doses. Start at one serving a day for the first three or four days; step up only if your gut tolerates it.

Vitamin C (50mg, 62% NRV). Ascorbic acid earns its place here for two reasons. Second, vitamin C contributes — to use the EFSA-authorised plain wording — to normal energy-yielding metabolism, to the reduction of tiredness and fatigue, to the normal function of the immune system, and to the protection of cells from oxidative stress. Boring, structural, daily.

Citrus bioflavonoids. The flavonoid family present in the white pith of oranges, lemons, and grapefruit — the part of the fruit most people throw away. Hesperidin, naringin, and rutin are the three best-studied. They earn a quiet seat at this table because traditional herbal practice has paired them with vitamin C for the better part of a century.

Sugar beet fibre (110mg). Sugar beet — Beta vulgaris, the same species as red beetroot but a different cultivar grown for sugar — leaves a fibre-rich pulp after the sugar is extracted. Sugar beet fibre, apple cider vinegar powder and fructo-oligosaccharides complete the formula. A small but useful contribution to daily fibre intake.

Apple cider vinegar powder. A concentrated, dried form of the same fermented apple juice that has been a kitchen staple for two thousand years.

Fructo-oligosaccharides. Short chains of fructose found naturally in onions, leeks, asparagus, bananas and chicory root.

Two capsules — one serving — on an empty stomach, with a glass of water. The bottle's traditional pairing is to follow the dose with a glass of orange juice, or freshly-squeezed lemon juice in water. The acidity helps the magnesium oxide and hydroxide dissolve and shifts a touch more of the elemental mineral into solution.

A note on grapefruit juice. It is sometimes recommended for the same acidity reason, but grapefruit interacts with statins (atorvastatin, simvastatin), several calcium-channel blockers, ciclosporin, and a handful of other prescription medicines through the CYP3A4 enzyme in the gut wall. If you take any prescription medication, skip the grapefruit and use orange or lemon water instead — and check with your pharmacist before starting grapefruit juice as a daily routine. Plain water is always fine.

You can repeat the dose up to four times a day. Most people sit comfortably at one or two servings. Magnesium contributes to normal muscle function and to the reduction of tiredness and fatigue.

If you find your stools are looser than usual, drop back to one serving a day and let the gut adjust. Sensitivity varies — some people tolerate four servings without any noticeable bowel effect; others find that two is plenty.

Magnesium works in the background. None of these are dramatic. All of them are the quiet absence of small daily insufficiencies that you'd stopped noticing because they had become the baseline.

If after eight weeks nothing has shifted, stop. A supplement that isn't doing anything for you isn't worth the money.

This is a food supplement — it complements a varied diet, doesn't replace one. If you have kidney disease, magnesium supplementation needs a clinician's input — the kidneys are the main route by which excess magnesium leaves the body, and impaired kidney function can let levels rise too high. If you are on diuretics, blood-pressure medication, or any prescription medicine, run this past your GP or pharmacist first — magnesium can interact with several drug classes. If you are pregnant or breastfeeding, talk to a healthcare professional before adding it.

Don't exceed four servings a day. Keep the bottle cool, dry, sealed, out of reach of children.

If you read this far, thank you. We tried to write the kind of page we'd want to read — no neon promises. Just a mineral the modern soil keeps losing, four forms of it in one capsule, a mineral in four forms, two capsules a serving.
