Capsid was founded by Dr Lisa Brigstocke, a GP with over 15 years’ experience working in the NHS. After seeing countless patients with viral illnesses - and facing her own daughter’s hospitalisation with flu - Lisa wanted a better way to make immune health simple and effective. Capsid is her answer: a clean, five-ingredient blend designed for everyday resilience.
“Antibiotic resistance is one of today’s biggest health threats, driven by the overuse of antibiotics. As an NHS doctor, I’ve seen first-hand how vital a strong immune system is in staying well. That’s why I created Capsid — a powerful nutraceutical designed to support your body’s natural defences, helping you stay healthy and well.”
Why Lisa created Capsid
Lisa began researching ingredients with the strongest evidence for immune support. Star anise (Illicium verum) quickly stood out – not only is it used to make antiviral medicines, but Illicium verum is also known for its potential to strengthen the body’s natural defences.
Combining star anise with vitamin C, vitamin D3, zinc and elderberry, Lisa created a simple blend, designed for everyday resilience. Each ingredient is carefully chosen for its role in supporting immune health, brought together in one simple daily supplement.
“My goal is to give people a clean, science-led alternative to ultra-processed products. Capsid is a nutraceutical – a food-derived supplement with ingredients selected for their evidence-based links to immune health.”
I want to make immune health clearer, simpler and more effective.
