Dry skin is often a sign of essential fatty acid deficiency, since healthy cell membranes are made up largely of fatty acids. When fatty acids are not available, skin may become rough and dry. Fatty acids are found in low mercury fish, or in purified fish oils. Dry skin will heal in 4-6 weeks with adequate consumption of oil. Occasionally a weak thyroid condition may prevent effectiveness of oils. Gluten sensitivity, low stomach acid, or gall bladder dysfunction may inhibit proper absorption of essential fatty acids.
To minimize dry skin, consider increasing consumption of essential fatty acids.
