Astaxanthin is a deep red-orange marine carotenoid pigment, Astaxanthin is considered a powerful naturally-occurring antioxidant.
It has been linked by researchers to many potential health benefits including healthier skin, physical endurance, heart health, joint pain, anti-inflammatory and may have anti cancer effects. Numerous studies have indicated that astaxanthin has potential health-promoting effects in the prevention and treatment of various diseases including chronic inflammatory diseases, metabolic syndrome, diabetes, diabetic nephropathy, cardiovascular diseases, gastrointestinal diseases, liver diseases, neurodegenerative diseases, eye diseases, skin diseases, exercise-induced fatigue and male infertility.
Carotenoids have gained much attention in recent years due to their beneficial effects on human health. Around 750 carotenoids have been identified and researched and they are most typically known for their antioxidant and anti-inflammatory effects.
This has simulant of Astaxanthin, but also some creation of Aspartic acid and the induced production of Dsup (damage suppressor protein) (by instructing RNA) this gene and the protein it produces is unique to the tardigrade, that suppresses the occurrence of DNA breaks by radiation. Tardigrade’s have an exceptional tolerance to harsh environmental stresses because of this, So generally it provides a robust protection from hydroxyl radicals and ionizing radiation, with a few more general protectant effects.
3 - 4 times is fine.
Of course the more long term advantages would be a far better survival rate for not well shielded space flight, or general exposure to radioactivity. On the rare chance this happens of course
