Question 1

How is 4mg different from 12mg?

Accepted Answer

Same brand, same source (Hawaiian-grown Haematococcus pluvialis microalgae), one-third the per-softgel astaxanthin dose. Lower-strength option for people starting astaxanthin or wanting a smaller daily dose.

Question 2

Where can I buy it?

Accepted Answer

Amazon UK at £35 is the listed retailer.

Question 3

What is astaxanthin?

Accepted Answer

A carotenoid antioxidant — typically marketed for skin, eye and exercise-recovery support.

Question 4

Is the IGEN cert a banned-substance test?

Accepted Answer

No — IGEN Non-GMO Tested verifies non-GMO sourcing only. For banned-substance certification on BioAstin, the 12mg Vegan SKU carries Informed Choice.

Question 5

Vegan?

Accepted Answer

The standard softgel uses an animal-gelatin shell. For a vegan BioAstin softgel, the 12mg Vegan SKU is the brand's vegan-formulated option.
