Theatre Nurses is a nurse-led health and wellbeing website focused on biohacking, longevity, and optimising health.
The site began as a resource for nurses working long, demanding shifts in NHS hospitals. Over time, it has grown into a space for anyone who wants to optimise their health, energy, and long-term wellbeing using practical, evidence-based approaches.
Much of the content focuses on supplements, nutrition, recipes, recovery, and lifestyle choices that support gut health, muscle, energy levels, and healthy ageing. Everything shared is grounded in clinical knowledge and current research, with a strong emphasis on safety.
Our Approach
Theatre Nurses is run by a small team of NHS nurses who stay up to date with current research and best practice. We aim to make complex health information easier to understand and apply in everyday life.
You won’t find extreme protocols or unrealistic advice here. The focus is on sensible, sustainable ways to support health — especially for people with busy lives.
Supplements & Transparency
Many of the articles on this site discuss supplements and how they may support health and longevity. For transparency, we partner with DoNotAge.
We chose DoNotAge because they are a health research organisation rather than a typical supplement brand. Their formulas are backed by clinical research and produced with a strong focus on purity, safety, and third-party testing. Any supplement recommendations shared on this site are selected carefully and with evidence in mind.
