6 Reasons Why Your Nails Are Weak and Brittle (and How to Fix Them Naturally)

Introduction
Your nails say a lot about your health. If they’re breaking, splitting, or weak—it’s not just cosmetic. I’m Dr. Agustín Landívar, and today I’ll explain 6 reasons why your nails may be brittle, and how to fix them from the inside out using natural remedies.
Biotin Deficiency
Biotin (Vitamin B7) is essential for keratin production. Without it, nails become soft and fragile.
👉 Take 2,500–5,000 mcg of biotin daily or eat more eggs, almonds, and spinach.
Iron Deficiency Anemia
Low iron reduces oxygen delivery to nail cells, causing them to thin, flatten, or crack.
👉 Get a ferritin blood test and increase iron-rich foods or take a supplement.

Thyroid Imbalance
Hypothyroidism often causes dry, weak nails that split easily.
👉 Test your thyroid (TSH, T3, T4) and treat naturally if needed.

Overexposure to Water or Chemicals
Constant hand washing, detergents, or nail polish removers strip nails of moisture and natural oils.
👉 Use gloves and apply coconut oil or castor oil daily.
Zinc Deficiency
Zinc is key for cell regeneration and nail structure.
👉 White spots on nails may also signal low zinc. Add pumpkin seeds, oysters, or take a 15–30 mg supplement.

Poor Digestion or Gut Health
If you’re not absorbing nutrients properly, your nails suffer.
👉 Add probiotics, digestive enzymes, and support liver function.
