Lifestyle Tips for Stronger Nails

  1. Hydrate – Drink plenty of water. Nails need moisture from the inside out.

  2. Moisturize – Use cuticle oil or hand cream daily.

  3. Wear gloves – When washing dishes or using harsh chemicals.

  4. Don’t bite or pick – Obvious, but worth saying.

  5. Give them a break – From polish and harsh removers.

  6. File, don’t cut – File in one direction to prevent splitting.


Supplements That May Help

If you can’t get enough from food alone:

Supplement Typical Dose Notes
Biotin 2.5-5 mg daily Well-studied for nail health
Iron As prescribed Only if deficient; excess iron is harmful
Zinc 15-30 mg daily With food to prevent stomach upset
Collagen peptides 10-20 g daily May improve nail strength

Always consult your doctor before starting supplements.


When to See a Doctor

While most nail ridges are harmless, see a healthcare provider if:

  • Ridges appear suddenly or are accompanied by other symptoms

  • Your nails are pitted, discolored, or separating from the nail bed

  • You have spoon-shaped nails (curved upward)

  • You have dark streaks under the nail

  • You’re concerned about an underlying condition
