Magnesium Oxide 400mg | 365 Capsules | Vit4ever

Vit4ever Magnesium Oxide 400 mg

A pot full of magnesium oxide with a simple promise: 400 mg of elemental magnesium per capsule, derived from 665 mg of magnesium oxide, and lasting for 365 days from the same pot. No complicated combinations, no superfluous additions. Simply a high-dose form for those who want to maintain their magnesium intake without complications.

Why Manufacturers Still Opt for Oxide

Magnesium oxide doesn't have the best reputation for absorption, yet it's found on many shelves. There's a practical reason for this. Magnesium never appears alone; it's always bound to another substance, and in the case of oxide, that substance is oxygen, a small, lightweight molecule. Thanks to this, magnesium oxide contains a proportionately large amount of elemental magnesium per gram, much more than citrate or bisglycinate, for example. This means that a compact capsule still delivers a substantial dose. There's also a cost aspect: the raw material is relatively inexpensive to produce, which keeps a high dosage affordable. For a manufacturer aiming to put 400 mg of magnesium into a single capsule, oxide is therefore an obvious choice. To achieve the same amount with bisglycinate, you'd quickly need two to three times the capsule volume.

The Absorption Debate, Honestly Explained

There's a persistent misconception about magnesium oxide. It's often said that inorganic forms like oxide are less well absorbed than organic forms like citrate or bisglycinate. There's some truth to this: per milligram ingested, the body absorbs a smaller proportion with oxide. But that's not the whole story. Since the elemental magnesium density is so high, a significant amount still remains for absorption per capsule. A 2012 study by Shechter and colleagues also showed that magnesium oxide allows for good storage of magnesium in cells after a few weeks. The difference therefore lies not only in what is absorbed per milligram, but also in the amount initially present in the capsule. Many wonder if magnesium oxide is therefore a bad choice. That's a bit hasty: it depends on what you're looking for. For the best absorption per milligram, bisglycinate or citrate are more interesting. For a high total dose and a simple formula, oxide is a logical option.

Oxide vs. Citrate, Bisglycinate, and Taurate

Anyone looking to supplement their magnesium intake quickly encounters a handful of forms, and they differ more than one might think. Citrate is bound to citric acid and is often perceived as gentle on digestion, with average absorption per milligram. Bisglycinate is associated with the amino acid glycine, is considered one of the best-absorbed forms, and is therefore often offered in lower dosages. Taurate combines magnesium with the amino acid taurine, which especially appeals to those who deliberately choose this specific bond. Oxide is not distinguished by absorption per milligram, but by its density: it simply holds more elemental magnesium in the same capsule. This makes it a practical choice for those who prefer not to swallow four or five capsules a day to meet their magnesium needs. If one nevertheless opts for another form, in practice one often has to take more capsules to reach a comparable amount of magnesium.

Who This Formula Is Suitable For

These capsules are for adults who want to supplement their magnesium intake simply, with a high dosage per capsule and without having to take multiple capsules a day. Think of people with busy schedules who don't want to think about their supplement three times a day, or those who simply want a year's supply without having to reorder in the meantime. The capsule shell is plant-based, which also makes magnesium oxide suitable for a vegan diet. The product is gluten-free, lactose-free, and magnesium stearate-free, and contains no other unnecessary additives. A known property of magnesium oxide is a laxative effect at higher doses: unabsorbed magnesium draws water into the intestine, an effect that is also deliberately exploited in practice, for example in products known as "milk of magnesia" for occasional and temporary digestive upset. As a dietary supplement, this works differently, as it involves daily and regular intake, not a single high dose. With the recommended daily capsule, this effect remains limited for most people, but if your intestines are sensitive, increase gradually and take the capsule with plenty of water. Magnesium contributes to normal muscle function, the reduction of fatigue, the normal functioning of the nervous system, and normal psychological function. It also plays a role in normal energy metabolism, good electrolyte balance, normal protein synthesis, and the process of cell division, and contributes to the maintenance of normal bones and teeth.

In summary: a high-dose magnesium oxide with 400 mg of elemental magnesium per capsule, in vegan capsules and with a year's supply per pot. A pragmatic choice for those who prefer to take just one capsule a day rather than several, and not have to order a new pot every month.
