Vitamin A.......

Vitamin A (Retinol) Blood Test, this is requested to detect Vitamin A Deficiency or Toxicity.

Retinol is the primary form of Vitamin A. Our bodies can't make Vitamin A, our dietary sources are really important to produce it - MEAT sources provide vitamin A (Retinol) while vegetables and fruit sources provide carotene (a substance that can be converted into vitamin A by the Liver)

Vitamin A is stored in the liver and fat tissues (it is fat-soluble), and healthy adults may have as much as 1 years worth stored in there bodies.

Our bodies holds a relatively stable concentration in the blood through our feedback system, this then releases Vitamin A from storage as needed and increases or decreases the efficiency of dietary vitamin A absorption.

Vitamin A deficiencies are rare in the UK however it may be cause through malnutrition or people who have Coeliac Disease, Cystic Fibrosis or Chronic Pancreatitis in the older generation and those with alcoholism & Liver Disease.

You can however have too much Vitamin A going on in your body, by overusing vitamin supplements! It can also occur sometimes when, in your diet you consume a high proportion of foods, from animal sources, that are high in Vitamin A, such as Liver.

The symptoms you may have for Vitamin A deficiency are:- Night Blindness Dry eyes, Hair & Skin Repeated Infection Anaemia

The symptoms you may have for Vitamin A toxicity are:- Headaches Double or blurred vision Fatigue Weaknesses Weight loss Hair loss Bone & joint pain.
