Warning Signs of Vitamin Deficiencies You Can Spot in the Mirror

19. Hair Loss and Biotin Deficiency

While hair loss can be distressing and is often linked to various factors, a severe biotin deficiency can be a contributing factor. Biotin, also known as Vitamin B7, is a crucial nutrient for the health of your hair, skin, and nails. Without sufficient biotin, your hair may become dry, brittle, and prone to breakage, leading to hair loss. While this deficiency is relatively rare, it can occur in individuals with certain health conditions or those who consume raw egg whites over an extended period. To combat this deficiency, increase your intake of biotin-rich foods like eggs, nuts, and whole grains.

20. Cracks at the Sides of the Mouth: Riboflavin and Niacin Deficiency

The uncomfortable cracks and sores that can appear at the corners of your mouth, known as angular cheilitis, can be a clear sign of more than just a single vitamin deficiency. While it's commonly linked to riboflavin (B2), it can also signal a lack of niacin (B3). These B vitamins are crucial for cellular repair and energy production. Without them, the sensitive skin at the mouth's corners is unable to heal properly, leading to persistent cracks and inflammation. To address this, incorporate foods rich in B vitamins, such as lean meats, eggs, legumes, and fortified cereals, into your diet.
