Frequently Asked Questions

What is astaxanthin and why is it considered such a powerful antioxidant?

Astaxanthin is a keto-carotenoid — the pigment responsible for the pink-red colour of salmon, shrimp, and flamingos. It is unique among antioxidants because it spans the full width of the cell membrane, protecting both the inner and outer layers simultaneously. It also does not become pro-oxidant when it neutralises free radicals, unlike some other carotenoids. This makes it one of the safest and most effective natural antioxidants available.*

Why is the AstaReal source of astaxanthin considered the best?

AstaReal® astaxanthin is produced from Haematococcus pluvialis microalgae cultivated in a controlled indoor environment without solvents. This results in a purer, more consistent product with verified potency and no contamination from pesticides or heavy metals. AstaReal® is backed by over 50 clinical studies and is widely regarded as the gold standard in astaxanthin supplementation.*

Can astaxanthin support skin health?

Yes. Clinical studies with AstaReal® astaxanthin have demonstrated improvements in skin elasticity, moisture content, and reduction of wrinkle depth with regular supplementation. Astaxanthin's ability to penetrate all skin layers from within makes it a powerful beauty-from-within supplement for healthy, youthful-looking skin.*

Is Doctor's Best Astaxanthin safe to take long-term?

Astaxanthin from natural sources has an excellent safety profile and is considered safe for long-term daily use in healthy adults. As with any supplement, consult your healthcare professional if you are pregnant, breastfeeding, or taking medications. Astaxanthin may intensify skin pigmentation slightly at high doses — this is harmless and consistent with its carotenoid nature.
