14 Subtle Signs of Vitamin and Mineral Deficiencies You Need to Know

13. Strange Cravings (Like Ice or Dirt)

Odd cravings for non-food items like ice, clay, or even dirt—behavior known as ‘pica’—may be your body’s subtle SOS for iron or zinc. While sometimes fleeting and harmless, persistent pica—especially in children or pregnant women—might need attention. Dr. Sethi highlights that these cravings aren’t silly or shameful but simply a unique way your body asks for more support. Adding more protein, beef, shellfish, pumpkin seeds, or iron-rich greens could help, and if cravings persist, a gentle health check is a positive next step.

14. Nighttime Teeth Grinding or Jaw Tension

Do you wake up with a sore jaw or find yourself clenching your teeth during sleep—or even in the middle of the day? Bruxism isn’t just about stress; emerging research points to magnesium or B vitamin gaps as underlying contributors. Teeth grinding can quietly wear on your well-being and dental health. Simple changes—like more spinach, whole grains, and nuts—may help relax muscles and nerves. If jaw discomfort or grinding continues no matter what you try, bringing it up at your next dental or medical visit can open the door to gentle, truly holistic support.
