Vitamin D deficiency could show up in nails through slow growth or peeling edges and sometimes along with muscle weakness or bone discomfort.
What Your Tongue’s Look and Feel Can Tell You About Vitamins
Your tongue can show vitamin health because changes in its color, coating or texture can signal when your body is low on important nutrients and a pale tongue often means low iron or vitamin B12 which keep your blood healthy and help prevent tiredness or dizziness.
