While it is not common in developed countries it is possible that low Vit A may be present. This comes with age, and poor diet and
hypothyroid situations. Thyroid hormone is responsible for converting betacarotene in vegetables to retinol . One cod liver oil cap a day (do not increase the dose) or one Vitamin A acetate 8000IU tablet a day (do not increase dose) may help.
Signs of Vitamin A deficiency are similar to Sjogren's.
