Dietary Supplements

Astaxanthin is known for its powerful antioxidant activity and related health benefits, thus widely used as a nutraceutical product or dietary supplement.

  • Astaxanthin has a unique polar structure and ability to donate electrons and stabilize free radicals, which terminates the damaging free radical chain reaction and thus maintains the cell integrity
  • Astaxanthin, like other carotenoids, can act as a quencher of singlet oxygen and other free radicals by absorbing the excited energy of singlet oxygen. In this way, it prevents cellular components or tissues from being damaged.
  • Astaxanthin offers protection against a broad range of human diseases like neuro-degenerative disorders. The antioxidant activity of astaxanthin is stronger than β-carotene and vitamin E by 40x and 1,000x respectively.
  • It also crosses the blood-brain barrier, which makes it available to the eye, brain and central nervous system to alleviate oxidative stress that contributes to ocular, and neurodegenerative diseases such as glaucoma and Alzheimer's.

The global algae astaxanthin market size in 2018 was about 80 tons valued at $450-500 million. Within the natural astaxanthin, the nutraceutical market was $170 million in 2018. The global astaxanthin market is expected to grow at a CAGR of about 4.5% over the next 3-4 years.
