Thyroid disorders, whether overactive or underactive, can also affect the health of your fingernails. You should always take such health factors into account and, if necessary, consult a specialist.

The importance of nutrient deficiencies and malnutrition

Nutrient deficiencies can be a major factor contributing to the development of brittle nails. A balanced diet is key to maintaining healthy nails.

Here are some nutrients whose deficiency can negatively affect the health of your nails:

Vitamin C deficiency: Vitamin C is essential for the production of collagen, a protein found in nails. A deficiency can lead to dry and brittle nails.

Vitamin D deficiency: A deficiency in vitamin D can weaken nails because this vitamin plays an important role in bone health, which is directly linked to nail health.

Vitamin E deficiency: Vitamin E helps maintain moisture in the skin and nails. A deficiency can lead to dry and brittle nails.

Iron deficiency: Iron is an essential component for the production of hemoglobin, which carries oxygen throughout the body. A deficiency can lead to brittle and pale nails.

Zinc deficiency: Zinc is an important nutrient for skin and nail health. A deficiency can lead to slower nail growth and brittle nails.

Magnesium deficiency: Magnesium helps in protein synthesis and cell repair. A deficiency can lead to brittle nails as it affects the overall health of the nails.

Biotin deficiency (vitamin B7): Biotin is known to promote hair, skin and nail health. A deficiency can lead to brittle, split and thin fingernails.

Omega-3 fatty acids deficiency: These fatty acids are necessary for your overall health, including nail health. A deficiency can lead to dry and brittle nails.

Protein deficiency: Since nails are made of keratin, a protein, a protein deficiency can lead to weak and brittle nails.

Calcium deficiency: Calcium is necessary for strong bones and nails. A deficiency can lead to brittle nails.

Expert tip: It is always advisable to consult a doctor or nutritionist if you notice any signs of nutrient deficiencies.

Genetic factors and causes

While environmental and dietary factors play a significant role in the health of your nails , genetic factors cannot be ignored either. Some people are genetically more prone to brittle nails, regardless of diet or lifestyle.

Genetic conditions such as,

  • genetic predisposition,
  • Ectodermal dysplasia,
  • Nail type
  • and nutrient utilization, can, for example, cause brittle nails.

Daily exposure to various chemicals and substances can also affect nail health :

  • Nail polishes
  • and other harsh chemicals can dry out and weaken nails.

It is essential to protect your nails as much as possible from these substances by regularly caring for your nails and wearing gloves.

Brittle nails in winter: Are environmental influences to blame?

Winter can be a tough time for our nails. The low temperatures and dry air can dry out the nails , making them more prone to breakage and cracking. To avoid this, it is advisable to moisturize the hands and nails well and wear gloves to protect them from the cold.

Expert tip: Especially in winter, you should give the cream time to absorb between applying cream to your hands and going outside. The water it contains can lead to frostbite of the skin and nails.

Stress and its effects on your nails

Stress can put a significant strain on our bodies and our nails are no exception. Chronic stress can cause hormonal imbalances that can negatively impact nail health.

In addition, stress can lead to bad habits such as nail biting, which further weakens nails. Develop effective stress management strategies to protect not only your mental health but also your physical health, including the health of your nails.
