Accurate, Trusted, Effortless
Understand Your Health. Backed by Independent Testing.
At Metabolics, we believe that optimal health starts with understanding what’s happening inside your body. Whether you’re making proactive choices about your wellness, troubleshooting symptoms, or supporting others in your clinical practice, testing provides the clarity to move forward with confidence.
That’s why we’ve partnered with Thriva, the UK’s leading provider of at-home blood testing, to bring you a trusted range of independent diagnostic kits. These tests offer deep insights into key biomarkers such as vitamin and mineral status, cholesterol, iron, and inflammation — all without needing to visit a clinic.
Each kit is easy to use and clinically approved. Using the Tasso+ self-collection device, you can draw a small sample of blood painlessly at home. Just return your sample in the prepaid envelope, and it’s analysed by a UKAS-accredited laboratory. Results are available within days via a secure, GDPR-compliant digital portal.
Your results are reviewed by a GMC-registered doctor and delivered as a clear, easy-to-understand GP report — with insights you can act on right away. Reports are accessed securely online and remain fully confidential.
Whether you’re an individual making informed choices, or a practitioner looking to personalise supplement protocols, these tests provide accurate, actionable insights that integrate seamlessly into your health routine or practice.
How It Works – Simple, Secure, Science-Led
Most people have no idea they’re low in essential nutrients until symptoms show up — and even then, they’re often missed or misdiagnosed.
In fact, many nutrient deficiencies — like low B12, Vitamin D, or iron — build up slowly over time and are only detected through testing.
That’s where we come in.
With our home blood testing kits, powered by Thriva, it’s easy to keep track of your internal health and make informed decisions before problems take hold.
