Calcium

The smart calcium formula. With calcium, vitamin D3 and K2 for optimal absorption.

plnktn calcium combines plant-based calcium from algae with vitamins D3 and K2 to create a complete formula that goes beyond standard calcium supplements.

Calcium alone isn't always the solution. Without the right co-factors, calcium can accumulate in the wrong places, such as in blood vessels, instead of in bones. This is known as the calcium paradox.

That's why this formula works with a clever trio:

  • Calcium from the algae Lithothamnium calcareum.
  • Vitamin D3 (from algae), which supports the absorption of calcium in the body.
  • Vitamin K2, which helps transport calcium to the bones.

This combination ensures that calcium is not only well absorbed but also reaches the right place.

Calcium is the most abundant mineral in the body and is needed for the maintenance of strong bones and teeth. It also contributes to normal muscle function, nerve conduction, and energy metabolism.

Our calcium comes from shed seaweed and is harvested without active collection. A more sustainable alternative to traditional mined calcium, with less environmental impact.

 

Not your standard calcium

Why calcium?

Did you know that calcium is the most abundant mineral in your body? Approximately 99% is found in your bones and teeth, providing strength. But that remaining 1% is just as important.

This small amount plays a crucial role in vital functions such as:

  • Contributes to normal energy-yielding metabolism
  • Contributes to normal muscle function
  • Contributes to normal cell division
  • Contributes to normal blood clotting

What makes your calcium unique?

Taking calcium alone can be risky. Calcium is supposed to end up in your bones and teeth, but that doesn't always happen. In some cases, calcium accumulates in the blood vessels, potentially leading to arteriosclerosis. This is called the calcium paradox: a deficiency in the bones, but an excess in the blood vessels.

We solve this by combining three nutrients that work together:

  • Calcium – natural and plant-based, extracted from the alga Lithothamnium calcareum
  • Vitamin D3 (from algae) – the key that maximizes calcium absorption in the intestines
  • Vitamin K2 – the "traffic controller" that directs calcium to the bones and keeps it out of the blood vessels

With our supplement, you meet your daily needs – with calcium in combination with vitamin D3 and vitamin K2.

How much calcium do you need per day?

The recommended daily intake (RDI) of calcium is around 800 mg per day. Many people do not achieve this through diet alone.

With our supplement, you get:

  • Calcium (Aquamin®) – 467 mg (58% RDI)
  • Vitamin D3 (from algae) – 5.5 µg (110% RDI)
  • Vitamin K2 – 75 µg (100% RDI)

This way, you supplement a large part of your daily requirement — in combination with vitamin D3 and K2 for optimal absorption and utilization.

What are the ingredients of your calcium?

Aquamin TG (Lithothamnium calcareum, corn starch), vitamin D3 (cholecalciferol, Vita-algae D®), vitamin K2 (MK-7), HPMC capsule.

Do I need extra calcium?

That depends on your diet and life stage. The average requirement is around 800 mg per day, but many people don't meet this. Teenagers, women over 50, and people who eat plant-based or dairy-free diets are particularly at higher risk of deficiency. In such cases, a supplement can help to complement your daily intake.
