Your Health deserves more than a quick GP check-up

If you’ve been told your blood pressure, cholesterol, or blood sugar levels are “a bit high”, VELLIO Health helps you understand why, and what to do about it, before medication becomes the only option.

We use advanced, non-invasive cardiometabolic VO₂ testing technology, supported by expertise in nutrition and exercise science.

This allows us to thoroughly assess your current health, analyse and identify potential pre-condition markers, and develop strategies to improve your health, performance, and long-term longevity.

Where data meets expertise.

We combine a science-based, expert-led approach to health, performance, and lifestyle optimisation. Based on your results and insights, we craft hyper-personalised wellness programmes tailored to your unique biology and needs, and work with you to achieve and maintain your longevity, health and performance goals.
