A crucial screen focusing on the three most common deficiencies in the UK: Vitamin D, Vitamin B12, and Folate. Deficiencies in these vitamins are associated with symptoms like fatigue, low mood, and poor immune function.
Tests Included
Vitamin D plays a vital role in maintaining healthy bones, teeth and muscles by helping your body absorb calcium and phosphate. It also supports normal immune function and contributes to muscle strength and general wellbeing. Low vitamin D levels are common in the UK and may contribute to tiredness, muscle weakness, bone pain and an increased risk of fractures. Measuring vitamin D helps identify deficiency and monitor response to supplementation.
Vitamin B12 is essential for healthy red blood cell production, normal nerve function and DNA synthesis. Low vitamin B12 levels may lead to fatigue, weakness, poor concentration, memory problems, numbness or tingling in the hands and feet, and anaemia. Deficiency may develop due to poor dietary intake, reduced absorption, certain medications or autoimmune conditions such as pernicious anaemia.
Folate is required for healthy red blood cell production, DNA synthesis and normal cell growth. It works closely with vitamin B12 and is particularly important during pregnancy to support normal fetal development. Low folate levels may contribute to fatigue, anemia and poor cell regeneration. Measuring folate alongside vitamin B12 helps investigate nutritional deficiencies and the causes of macrocytic anemia.
Important Pre-Test Information
B12 Injections: If you have received a Vitamin B12 injection, the test should ideally be delayed by 7 to 10 days for an accurate baseline assessment.
Biotin: Please stop taking Biotin supplements 7 days before the test, as they can interfere with vitamin B12 results.
