Viridian's Astaxanthin is a carotenoid sourced from freshwater microalgae ( Haematococcus pluvialis ), one of the richest sources of natural astaxanthin. Astaxanthin is cultivated using the pristine waters from the Himalayas in an ideal climate which allows the microalgae to flourish without the requirement for any artificial heating or cooling. As well as minimising the environmental impact of production, the exposure to natural sunlight gives this carotenoid its characteristic vivid red colour as the microalgae reacts to UV light. Astaxanthin is an antioxidant which cannot be produced by the

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as VIRIDIAN INTERNATIONAL LIMITED, number 03750310. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Stated by the company: "our in-house team of qualified nutritionists" Source.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
No majority shareholding traced outside the UK. Companies House.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
