Re: Persistent Vitamin A Deficiency since 2 years

The 3 culprits I could dig up:

1/ Deficiency of zinc or other minerals - do a hair test from Trace Elements which is affordable.

2/ Malabsorption issue.

3/ Incorrect form.

Zinc

Zinc deficiency is thought to interfere with vitamin A metabolism in several ways: (1) zinc deficiency results in decreased synthesis of retinol binding protein (RBP), which transports retinol through the circulation to tissues (e.g., the retina) and also protects the organism against potential toxicity of retinol; (2) zinc deficiency results in decreased activity of the enzyme that releases retinol from its storage form, retinyl palmitate, in the liver; and (3) zinc is required for the enzyme that converts retinol into retinal (8, 9). At present, the health consequences of zinc deficiency on vitamin A nutritional status in humans are unclear (10). Tweet
