Overview:

Ensure your body is absorbing and using vitamin B12 effectively with our Active Vitamin B12 Test. This test measures the biologically active form of B12, which is essential for red blood cell formation, nerve function, and DNA production. It’s particularly useful for diagnosing B12 deficiencies, even if your total vitamin B12 levels appear normal.

This Active Vitamin B12 Test is recommended by NICE guidelines in place of the standard NHS vitamin B12 test that measures only the total vitamin B12 level. An Active Vitamin B12 Test gives you the most accurate way of finding out if you have a deficiency.

If you're experiencing symptoms like fatigue, weakness, memory issues, or tingling in your hands and feet, this test provides the insights you need to take control of your health and address potential deficiencies. Get fast, accurate results and improve your energy and wellbeing today!
