Our skin is often the first visible indicator of internal health issues. Nutrient deficiencies can silently affect your body long before other symptoms appear. Here are nine common nutrient deficiencies and the skin changes they can trigger.

Sources: Carrots, sweet potatoes, spinach, kale, liver, fortified dairy products.
Tip: A deficiency often occurs in those with low-fat diets or fat malabsorption, as vitamin a is fat-soluble.
