Long days, plenty of sweat, too few vegetables: when your electrolyte balance needs topping up
Magnesium Plus by Cosmoterra, based in Austria's Lungau region, brings magnesium, potassium, calcium and vitamin B1 together in one capsule, rounded off with citrus bioflavonoids. Two capsules a day, done.
💪
Normal muscle function
Magnesium, potassium and calcium contribute to normal muscle function. Three minerals that work as a team in the muscle: calcium for contraction, magnesium and potassium for release and signal transmission.
❤️
Normal heart function and blood pressure
Thiamine (vitamin B1) contributes to the normal function of the heart. Potassium contributes to the maintenance of normal blood pressure.
🧠
Nervous system and electrolyte balance
Magnesium contributes to electrolyte balance. Potassium contributes to the normal functioning of the nervous system, and calcium contributes to normal neurotransmission.
😴
Less tiredness, normal energy metabolism
Magnesium contributes to the reduction of tiredness and fatigue. Magnesium, calcium and vitamin B1 contribute to normal energy-yielding metabolism.
Sound familiar? After a long bike ride, a hot day on site or a week of too much coffee and too few vegetables, the body feels drained. Minerals such as magnesium and potassium leave us with every drop of sweat. And the foods that would replace them (pulses, nuts, wholegrains, potatoes) rarely make it onto the plate often enough.
That is exactly the gap this combination is built for. Magnesium and potassium do most of their work inside the cells, calcium mainly outside them. Only the interplay of these three electrolytes keeps the electrical signals in muscle and nerve cells in balance. Vitamin B1 acts as a coenzyme in carbohydrate metabolism, right where food is turned into energy. The citrus bioflavonoids complete the formula as a plant-based companion.
Behind the product is Cosmoterra, a company based in Unternberg in the Lungau region of Salzburg with roots in nutritional counselling. Its motto "…ergänzt was fehlt" (adding what is missing) sums up the approach: combine nutrients deliberately rather than pushing single ingredients to high doses. The nutrient values are based on average analyses, and the capsule shell is made from plant cellulose rather than gelatine.

Trade name: Food supplement with magnesium, potassium, calcium and citrus bioflavonoids
Ingredients: Potassium hydrogen carbonate, magnesium oxide, calcium carbonate, capsule shell hydroxypropyl methylcellulose, anti-caking agent magnesium salts of fatty acids, citrus bioflavonoids, thiamine mononitrate. Free from gluten and lactose.
Net quantity: 120 capsules = 109.2 g
Why magnesium oxide rather than citrate or bisglycinate?
Magnesium oxide is the most compact magnesium compound: around 60 percent of its weight is pure magnesium. Citrate comes in at roughly 16 percent, bisglycinate at about 14 percent. That is why 301 mg of magnesium fits into two capsules here, whereas organic compounds would need considerably more capsules or a powder for the same amount. If you want potassium and calcium in the same capsule as well, a space-saving form is hard to avoid.
What do carbonate and hydrogen carbonate mean in the nutrient table?
Minerals never come alone; they always arrive as a salt with a partner ion. Here, potassium is bound to hydrogen carbonate and calcium to carbonate. Both counter-ions are shown transparently in the table because they make up a relevant share of the capsule contents. They are not active ingredients in their own right, but the chemical carrier that keeps potassium and calcium in a stable, powdered form.
⚠️ Mandatory information: Do not exceed the recommended daily dose. Food supplements are not a substitute for a varied and balanced diet or a healthy lifestyle. Keep out of reach of children.
📦 Storage: Store in a dry place and not above room temperature.
💬 Frequently asked questions
-
Who is Magnesium Plus for?+
For people with an increased need for minerals: active athletes, anyone who sweats a lot or does physical work, and everyone whose everyday diet is short on pulses, nuts and wholegrains. If you have been taking magnesium and potassium separately, the combination saves you two tubs.
-
How does Magnesium Plus differ from plain magnesium?+
A single-ingredient product delivers magnesium only. Here you also get potassium, calcium and vitamin B1, the partners magnesium works with in muscle and nerve cells anyway. The "Plus" in the name stands for exactly that addition, not for a higher dose.
-
When is the best time to take the capsules?+
One capsule twice a day, spread across the day, each with plenty of liquid. Two separate intakes are deliberate: the mineral amount is spread out instead of arriving all at once.
-
Is the capsule vegan, gluten-free and lactose-free?+
Free from gluten and lactose: yes. The capsule shell is made of hydroxypropyl methylcellulose, a cellulose derivative, not gelatine. There is no explicit vegan declaration from the manufacturer, which is why we do not advertise the product as vegan.
-
Why is potassium included?+
Potassium is the most abundant mineral inside our cells and is lost through sweat much like magnesium. Many magnesium products leave it out. Here, two capsules provide 15 percent of the reference intake, as potassium hydrogen carbonate.
-
What are citrus bioflavonoids?+
Secondary plant compounds from citrus fruit, mainly from the white pith of oranges and lemons. Well-known examples are hesperidin and rutin. They complete the formula as a plant-based companion in a small amount (6 mg per daily dose).
