£29.35

Magnesium is an important mineral, playing a key role in over 300 processes in the human body. Viridian’s Organic Magnesium is an innovative plant-sourced form of this essential micronutrient. Derived from a type of wild seaweed known as sea lettuce (Ulva lactuca), the leaf-like structures are naturally enormously abundant in vitamins and minerals. They grow on rocky shores and seabeds before being harvested and carefully dried to preserve their rich levels of magnesium. It is the first certified organic magnesium on the UK market, having been produced without the use of pesticides, fertiliser

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.
