If you're looking for British-owned supplement companies, rather than international brands that simply sell in the UK, I'd focus on ownership, manufacturing standards, ingredient transparency and the range of supplements available.
One important distinction: British-owned, British-founded and manufactured in Britain are three different things. The companies below are a useful starting point, with ownership and manufacturing claims distinguished wherever possible.
## British-owned supplement companies to consider

## Which companies would I shortlist?
It depends on what matters most to you\:
| Your priority | Companies to investigate |
|--------|--------|
| British ownership and independence | Cytoplan, G&G Vitamins |
| Established British vitamin brand | Vitabiotics |
| UK manufacturing | Ivvion, Nature's Best |
| Wholefood and practitioner-oriented supplements | Cytoplan |
| Family and children's nutrition | APOKRA, Vitabiotics |
| Greens and newer wellness products | Emerald Nutrition |
One notable exclusion is Healthspan\: although it was founded in Guernsey, it was acquired by Norwegian group Orkla Health in 2022, so it does not meet a strict British-owned requirement. www.healthspan.co.uk
These are research leads, not a clinical quality ranking. Before buying, check the exact ingredient forms and doses, independent testing, manufacturing standards and whether the evidence supports the product's claims.
