Astaxanthin is a carotenoid unlike any other; it’s a potent, bioactive antioxidant synthesized by microalgae, bacteria, and yeasts. Ubiquitous in nature, especially around our marine life - it’s synthesized by microalgae and phytoplankton, which subsequently accumulates in sea life higher up the food chain. Visually, it’s a red-orange pigment, responsible for the rustic autumnal leaves we see each year and the colouring of prawns, salmon, and crayfish. Although astaxanthin can be synthesized by plants, bacteria, and microalgae - the chlorophyte alga Haematococcus pluvialis has the highest capacity to accumulate astaxanthin. Therefore, it is considered the crème de la crème source for nutraceutical and beauty purposes.
