Why is this the first supplement our therapists recommend?

Magnesium is one of the most popular supplements of our time. Many people use it and feel good about it. But most magnesium supplements contain a single form of magnesium, bound to a synthetic carrier such as citrate or bisglycinate. That works, but it misses something essential.

Your body does not only need magnesium. It needs the full spectrum of minerals and trace elements that function together with magnesium. As a population, we do not so much have a vitamin deficiency, but rather a mineral deficiency caused by decades of soil depletion. Addressing that deficiency is a far more important matter than most people realise, and the first recommendation from Kala Health’s product developer and therapists to anyone looking to make a meaningful change in their health.

Magnesium Complex Powder is the answer to that philosophy. It is not isolated magnesium, but a complete mineral complex obtained from concentrated seawater of the Atlantic Ocean. In addition to 350 mg of elemental magnesium per scoop, it contains all other minerals and trace elements naturally present in seawater: more than 75 in total. All in ionic form, and therefore directly absorbable by the body.

Why is it not a good idea to take a single mineral long term?

Minerals do not work in isolation. Each mineral affects the absorption, metabolism or excretion of many other minerals and trace elements. Taking high doses of a single mineral over a prolonged period can disrupt that balance. The figure below makes this visible: the lines show how strongly minerals and trace elements interact with one another. The web of interactions is so complex that it is unwise to take a limited number of minerals in higher concentrations without considering the whole picture.

This is precisely the reason why Kala Health developed the Magnesium Complex. Because the product is based on seawater concentrate, it contains not only magnesium but also all other minerals and trace elements in their natural, mutually balanced ratios. The formula is therefore far more balanced than any isolated magnesium supplement.

What makes seawater the ideal source of minerals for humans?

The mineral composition of seawater remarkably closely matches the composition of the extracellular fluid in humans. This is the fluid that surrounds all our cells and makes up one fifth of all our body fluid. Evolutionary biologists see this as indirect evidence that all land-based life forms once originated from the sea.

This makes seawater an exceptionally valuable source of nutrition. It contains all 75 minerals and trace elements in the right ratios to one another. Virtually all minerals are present in the form of positively charged ions, just as in the body itself. Minerals in ionic form pass through the intestinal wall easily and are therefore efficiently absorbed.

Why have minerals and trace elements become scarcer in our food?

Paul Bergner collected mineral content data from foods dating back to 1914. His analysis shows that over the course of the last century, the average mineral content in foods decreased by a factor of 5. The cause: the rise of intensive agriculture, where farmland is selectively fertilised with synthetic fertilisers containing only a limited number of minerals. All other minerals and trace elements are slowly depleted from the soil, without being replenished.

The consequence: even people who eat a varied diet take in fewer minerals through their food than a century ago. A supplement that offers the full spectrum, in the ratios as nature intended, is therefore not a luxury but a logical first step.

What does the science say: is magnesium from seawater concentrate actually better absorbed?

Yes. A recently published study in the scientific journal Nutrients compared the bioavailability of magnesium from different sources: seawater magnesium (Aquamin Mg Soluble, the same raw material as in this product), magnesium oxide and two forms of magnesium bisglycinate (Demehin et al., 2026).

The researchers used the standardised INFOGEST digestion model, which simulates the conditions in the human gastrointestinal tract, followed by transport across a Caco-2 cell layer: a validated scientific model for the human intestinal wall. The results showed that seawater magnesium had a significantly higher bioavailability than magnesium bisglycinate when digested together with food. That is precisely the situation that occurs in practice: you take your supplement with a meal.

Health benefits of magnesium

Magnesium is involved in the function of more than 300 enzymes in the body. The significance of magnesium is therefore difficult to overstate, and that is also why the list of officially authorised health claims for magnesium is remarkably long:

Who is Magnesium Complex Powder suitable for?

Magnesium Complex Powder has been developed for anyone who wants to supplement their daily diet with a complete mineral complex rather than isolated magnesium. The product is 100% vegan and free from yeast, lactose and gluten. Dissolve it in water, a smoothie or any other drink of your choice: you decide how you take it.

The container holds 500 grams. At the recommended daily dose of 1 gram per day, that is sufficient for over a year.

The Magnesium Complex range from Kala Health

In addition to the powder, we offer two capsule formulations based on the same marine raw materials. The Magnesium Complex Capsules contain 100% seawater concentrate: 211 mg elemental magnesium per capsule. The Magnesium & Calcium formula combines seawater concentrate with the red algae Lithothamnion Calcareum in a balanced ratio of 113 mg magnesium and 94 mg calcium per capsule. All three products contain the full spectrum of 70+ minerals and trace elements.

All variants contain exclusively natural, marine raw materials and the full spectrum of minerals and trace elements.

Kala Health: product developer, manufacturer and your therapeutic adviser since 1997

Kala Health was founded in 1997 by Paul Klein Breteler, and we are a product developer and manufacturer. The Magnesium Complex was personally formulated by Paul, based on the principle that a mineral supplement must be complete: not a single mineral in a high dose, but the full spectrum in the ratios as nature provides.

Every package of Magnesium Complex Powder is produced in our own FSSC 22000 certified facility in the Netherlands. From raw material analysis to filling and packaging: everything takes place in-house, under direct supervision of our quality team. The raw material is tested before it enters our factory and the finished product is tested again after production. Only after approval is the product packaged and shipped.

What sets us apart is the combination of production and advice. We now work with a team of nutrition specialists, our own therapist and a pharmacist. When you call or email with a question about this product, you speak with professionals who know the subject matter in detail. That personal advice is always free of charge and without obligation.
