About Brittica
Science-led supplements,
sold transparently.
Brittica is a UK retailer of Paragon Vitality food supplements, based in Leeds. We sell three focused formulas and show every dose, test and study behind them.
Who we are
Brittica is an independent UK online retailer of Paragon Vitality food supplements, based at 18 Arthington Court, Moor Road, Leeds, LS10 2LW. We sell directly to customers in the UK, Ireland, the European Union and the United States.
What we sell
Three focused formulas, each taken as two capsules a day, with every ingredient dose printed on the label and on this website:
Ca-AKG+: Energy, vitality and healthy maturing in one daily serving.
GlycoShift: Blood-sugar balance and steady metabolic energy.
Supple X: Complete joint and mobility nutrition in one daily serving.
How we check quality
Our formulas are made in a GMP-certified, ISO-accredited facility. Batches are independently assayed: for Ca-AKG+ batch 2026050201, all nine ingredients were confirmed within specification, and microbiology and heavy metals were also tested. Allergens are declared on every label and product page.
How we talk about health
We only use health claims authorised in the UK, link to published research for every ingredient in our science library, and never present single-ingredient studies as proof of what a finished formula does.
