Welcome to one of our Rightangled Test Explainers.

In this video we look in more depth at our Fitness Health blood test — why mineral levels and hydration matter for training and recovery, the markers measured, and the process from ordering through to reviewing your results online.

Markers such as iron, vitamin D and thyroid function have a direct effect on energy, performance and recovery, and are worth ruling out if your training has stalled or you are unusually fatigued.

Browse our current range of home blood tests and DNA tests. All results are reviewed by our clinical team, which includes GPhC-registered independent prescribers, with medical oversight from our doctor, Dr Abdullah.
