Optimising strength, focus & energy after 40
Olivia Herlihy

Hi, I’m Olivia, a Registered Nurse with an interest in biohacking, wellness, and longevity. I originally created this website as a resource for other nurses, to help them optimise their health while working long hours in NHS hospitals. Since then it has expanded and become a space for anyone who wants to live a healthier life. The site is run by a small team of NHS nurses who focus on practical, evidence-based ways to support health, energy, and long-term wellbeing.

Just so you know, I have partnered with DoNotAge to help point you towards the best quality supplements. I chose this brand because they are a health research organisation, rather than a supplement company, and they create clinically backed formulas with a strong focus on purity and safety.
