Warning Signs of Vitamin Deficiencies You Can Spot in the Mirror

39. A 'Sandpaper-Like' Rash on the Arms: Vitamin A Deficiency

Vitamin A is essential for the healthy turnover and maintenance of your skin cells. When you don't get enough of this nutrient, a protein called keratin can build up in your hair follicles, leading to those small, rough bumps that feel like sandpaper. This condition can be a tell-tale sign that your body's cellular regeneration is compromised. You can address it by adding foods rich in Vitamin A, such as carrots, sweet potatoes, and leafy greens, to your diet.

40. Cracks at the Sides of Your Nose: Riboflavin (B2) Deficiency

If you notice persistent, flaky, and red cracks at the corners of your nose, it could be more than just dry skin. This condition, known as seborrheic dermatitis, is a subtle but clear sign of a riboflavin (Vitamin B2) deficiency. Riboflavin is essential for cellular repair and energy production, and without enough of it, the delicate skin in these areas struggles to regenerate properly. This can lead to persistent inflammation and peeling. To address this, make sure to add foods rich in B2 like milk, yogurt, eggs, and lean meats to your diet.
