Vitamin Screen I

The Vitamin Screen I is a focused blood test that measures two of the most clinically important vitamins: vitamin D (25-OH) and vitamin B12. It is designed for anyone experiencing persistent tiredness, low mood, muscle aches, or cognitive fog, and for those who simply want to confirm their levels are optimal. This screen is particularly useful if you follow a plant-based diet, have limited sun exposure, are over 50, or take medications that can affect vitamin absorption.

Vitamin D (25-OH)
- The best single marker of your overall vitamin D status.
- Essential for calcium absorption, bone strength, immune defence, and muscle function.
- Low levels are linked to bone pain, frequent infections, and low mood.

Vitamin B12
- Vital for red blood cell formation, nerve function, and DNA synthesis.
- Deficiency can cause fatigue, tingling in the hands and feet, memory difficulties, and a specific type of anaemia.
- At-risk groups include vegans, vegetarians, older adults, and those with digestive conditions affecting absorption.

Why it matters
Vitamin D and B12 deficiencies are common, often silent, and frequently missed. Correcting them can restore energy, protect your bones and nerves, and support normal immune and cognitive function. This screen gives you and your doctor the clarity needed to act with confidence.
