The most important vitamins and minerals for nail health
.
What nutrients affect the condition of our nails?
.
B vitamins
.
This group of vitamins is involved in many key processes in the body. Your nails are particularly looked after by vitamin B12 (cobalamin) and B9 (folic acid). Vitamin B12 plays an important role in iron absorption and red blood cell development.
Both of these compounds are essential for maintaining strong and healthy nails. Vitamin B9 is important for nail growth and health as it contributes to the formation of red blood cells and the development of new cells.
See more better vitamins in the articles:
Biotin
.
That's right, biotin (otherwise known as vitamin B7 or vitamin H) is one of the B vitamins, but it deserves special mention. It helps in the metabolism of protein-building amino acids, which are essential for nail growth. Research suggests that a diet rich in biotin strengthensand brittle and fragile nails.
Biotin - the queen among beauty vitamins.
.Read how it takes care of you in the article: Biotin - what it is, action, deficiency, expert opinion
.Zinc
.
Zinc is needed for cell growth and division in our body. Nails are made up of cells that grow and divide rapidly, so a constant supply of zinc is needed to supportand healthy nail growth. Zinc is also essential for the production and function of hormones, abnormal concentrations of which can manifestand poor nail health.
Important!
White spots on the nails can be a symptom ofand a deficiency of calcium or zinc in the body, but also result from, among other things, damage to the plate, skin diseases, allergies.
Iron
.
Iron produces red blood cells that carry oxygen to the organs and every cell in our body, including the nails. Iron deficiencies impairand this important function. Deficiency of this element can lead to deformities of the nail plate (furrowing, concavity, 'spooniness').
Omega acids
.
Omega acids have antioxidant and anti-inflammatory effects. They can reduce inflammation in the nail bed, which nourishes and supportsand the health of the cells that give rise to new plate. A deficiency of these fatty acids can result in dry and brittleand nails.
Collagen
.
Type I collagen is a building block of, among other things, the nail plate. It affectsand the condition of the nail, as well as the skin around it. In one study participants consumed collagen for six months. After this treatment, they reported an improvement in the condition of their nails and a reduction in the frequency of fractures.
Learn more about collagen in the articles:
Proteins
.
Nails are made up of a fibrous protein - keratin. It is what gives the nails their elasticity and strengthens the plate. Consuming sufficient protein in the diet is essential to increase the production of keratin and thus create strong nails. The average person with average physical activity should consume 1.3g of protein per kg of body weightand. How much should you eat? Calculate!
Vitamin C
.
This is a busy vitamin that has a multisystemic effectand on our body. While it improves wound healing, acts as an antioxidant and delays the ageing process, it still has time to produce collagen . This is the protein that gives shape, structure and integrity to many tissues and is the building block of nails, hair and teeth. Vitamin C is amazing!
Interesting facts
It's unfair, but... men's nails and hair grow faster! The only exception is during pregnancyand, when the growth rate matches that of "men" or is even faster.
.
When to take supplements and vitamins for nails?
.
Support your nails when they need it. However, before starting supplements, do blood tests for vitamin and mineral deficiencies and test your thyroid hormone levels. Consult your doctor for the results.
Why get tested?
.
- Ensure yourself if and what deficiencies you have - you won't be supplementing blindly. .
- By knowing what your specific deficiency is, you can save money and buy one rather than three dietary supplements.
- If you have a deficiency, you'll be able to make the most of it.
- Excess does harm! It's better to be sure of the nutrients your body needs.
- .
Deficiency testing
.
For nail problems such as brittleness, splitting, brittleness, plate distortion, it is a good idea to carry out the following blood tests to determine the concentration of:
- zinc, .
- iron, .
- ferritin, .
- vitamin D3, .
- vitamin B12, .
- transferrin (transports iron in the blood). .
Thyroid tests
.
An abnormal concentration of thyroid hormones can manifest as deterioration of our nails.
Doing the following tests will give you a broad diagnostic picture and allow your doctor to more accurately identify the problem:
.
- thyroid hormones - TSH, FT-3, FT-4, .
- extended morphology, .
