Struggling with persistent dark circles under your eyes? While lack of sleep and stress are common factors, low potassium levels could also be a hidden cause. Inadequate potassium can lead to poor circulation and fluid retention, exacerbating the appearance of dark circles. If you notice darker under-eye shadows than usual, consider increasing your potassium intake. Foods like beans, dried fruits, and yogurt are excellent sources of this essential mineral. A straightforward adjustment to your diet could help reduce those stubborn dark circles.
