What is astaxanthin and where does the active compound come from?
Astaxanthin is a reddish carotenoid in the xanthophyll group. In nature it is produced primarily by the freshwater microalga Haematococcus pluvialis when it is under stress such as intense UV light or limited nutrients. The pigment acts like a natural “sunscreen” and turns the alga deep red.
Through the food chain, astaxanthin accumulates in krill, salmon, and flamingos, which gives them their characteristic color. For Heilnatura, the alga is cultivated in closed photobioreactors under controlled conditions, the astaxanthin is then gently extracted, and filled into a plant-based HPMC capsule.
The result is a 100% natural, vegan antioxidant with no synthetic additives and no genetic engineering.
