Are you taking supplements based on guesswork? This test takes the guesswork out of it. Using a simple at-home Tasso device — which attaches to your upper arm and requires no finger-prick — you collect a small blood sample and post it to our UK-certified laboratory. Your results arrive as a clear, easy-to-read wellness report.

Choose from three tiers depending on how much insight you want:

Quick Nutrient Check A focused check of the most common nutritional gaps: Vitamin D, Vitamin B12, Folate and Ferritin.

Personalised Supplement Test (Most Popular) Everything in the Quick Nutrient Check, plus Iron, TIBC, Magnesium, CRP, Albumin, Total Protein, Urea, Creatinine, ALT and ALP.

Deep Dive: Why You Still Feel Off Everything in the Personalised Supplement Test, plus Homocysteine, TSH, Free T4, Testosterone and SHBG — for a deeper look at energy, metabolism and hormone-related markers.
