Nutrition Blood Test

The Nutrition panel tests vitamin D, vitamin B12, folate, ferritin (iron stores), serum iron, TIBC (iron-binding capacity), magnesium, zinc, and phosphate. These are the key nutritional markers that drive energy, immunity, hair health, mood, and cognitive function.

Yes. Dietary intake does not always translate to adequate blood levels — absorption, gut health, genetics, and medication interactions all play a role. Someone eating a balanced diet can still be deficient in vitamin D (limited UK sunlight), B12 (especially vegetarians and vegans), or iron (women with heavy periods). A blood test measures what your body actually has, not what you ate.

Especially if you take supplements. Many people supplement blindly based on general advice rather than actual need. Testing shows whether your current supplements are working, whether doses need adjusting, and whether you are taking anything you do not actually need — saving money and avoiding unnecessary intake.

The Nutrition panel is particularly valuable for vegetarians and vegans, who are at higher risk of B12, iron, zinc, and sometimes folate deficiency. B12 is found almost exclusively in animal products, and plant-based iron (non-haem) is less readily absorbed than animal-based iron. Testing confirms whether supplementation is maintaining adequate levels.

Your results identify exactly which nutritional markers are low, borderline, or optimal. Helvy then provides personalised recommendations based on what your blood actually shows — not a generic supplement stack. If your vitamin D is low but your B12 is fine, you will only be recommended vitamin D.
