About the product
Almost 100 percent of your calcium is stored in your bones and teeth – and your body cannot produce it on its own. If it doesn't get enough, it draws on your bones. So calcium isn't optional, it's essential – the only question is which source you choose.
What makes our Natural Calcium special:
Our calcium comes from Lithothamnium red algae – a natural marine alga that stores calcium together with other minerals. No chalk, no lab-made calcium carbonate. Three capsules provide 690 mg of calcium (86% NRV), with just two ingredients in total.
Calcium contributes to:
- ✔ the maintenance of normal bones
- ✔ the maintenance of normal teeth
- ✔ normal muscle function
- ✔ normal energy-yielding metabolism
- ✔ normal blood clotting
- ✔ normal neurotransmission between nerve cells
Your benefits at a glance:
- ✔ Natural algae calcium from Lithothamnium red algae
- ✔ 690 mg of calcium per daily serving (86% NRV)
- ✔ Just 2 ingredients: algae powder and a vegan capsule shell
- ✔ 100% vegan – the plant-based alternative to dairy
- ✔ Made in Germany, independently lab-tested
- ✔ 180-day money-back guarantee – you take zero risk
Especially for you if...
...you eat little or no dairy, lead an active lifestyle, or want to invest in your bones for the long term. 3 capsules with a meal – and your calcium account is balanced.

Capsules or powder?
Where the difference really shows in everyday life.
| Surpresa Natural capsules | Nutrient powder |
|---|---|
| Taste-neutral | Grassy, bitter taste |
| Just swallow – done | Needs flavourings & sweeteners* |
| Precisely pre-dosed | Measure it yourself |
| No mixing, no measuring | Clumps quickly |
| Ideal on the go | Dust & residue |
| Capsule shell protects the ingredients | Absorbs moisture – clumps over time |
| Long shelf life, even after opening | Needs airtight storage |
* Powders often need flavourings and sweeteners to mask their own taste. Our capsules do without.
