Five nutrition tips for growing strong nails

Five nutrition tips for growing strong nails

Your nails can be a reflection of your inner health and dietary habits.  If nails do not get sufficient nourishment from the inside, nail growth can slow down and become brittle. Here are 5 top tips for your diet for healthy nails. 

What are nails made of?

Nails are made up of layers of a protein known as keratin.  Keratin is also found in skin and hair and when they're fed the right nutrients, your skin, nails and hair all naturally grow stronger and healthier.

Changes or abnormalities in your fingernails can be indicative of a nutritional imbalance or deficiency so eating the correct nutrients can help your nails grow stronger and more resistant to breakage and deterioration.

A poor diet can lead to other nail problems such as dry or brittle nails, horizontal or vertical ridges on nails, curved nail ends, darkened nails, splitting, hangnails, white lines or spots and abnormalities in nail colour.

Best foods for strong nails

A nutrient-rich and balanced diet is important to help nourish your body and can promote healthy fingernails.

1. Ensure healthy protein intake

Nails are largely made up of a fibrous protein called Keratin which contributes to your nail strength, preventing it from damage. Including protein-rich foods to your diet is necessary for maintaining strong and healthy nail plates.

A lack of protein in the diet may lead to nails becoming thin, brittle and weak, and slow down the rate of nail growth. White bands on your nails may also be a sign of inadequate protein intake.

Organic chicken, eggs, lean red meat and fish are good sources of animal-based protein, and there are lots of plant-based sources too including tofu, lentils, quinoa, soya, raw nuts and seeds.

2. Add essential fatty acids to your diet

Omega-3 and omega-6 are essential fatty acids that provide moisture and nourishment to your nails, making them appear shinier and healthier. An insufficient amount can cause your nails to become dry and break easily.

Increasing your intake of omega-3 and omega-6 fatty acids helps to stimulate the cells in the nail bed, reducing inflammation and promoting the absorption of nutrients, which prevents brittle nails and weak tips.

Oily fish such as salmon and mackerel, as well as raw nuts and seeds especially walnuts, chia seeds, and flaxseed are good sources. Flaxseed and flaxseed oil are a particularly valuable source of essential fatty acids as they are rich in omega-3 and omega-6 fatty acids which are known to strengthen nails.

3. Focus on Zinc & Selenium

Zinc and Selenium are essential trace elements with a significant effect on nail health. Zinc plays an important role in protein synthesis and is necessary for tissue growth. Zinc deficiency is associated with brittle nails, and can cause vertical ridges and indentations to form on the nails. White spots or lines on your nails can indicate that you might be low in Zinc.

Pumpkin seeds, walnuts and brazil nuts are great sources of Zinc, Selenium and essential fatty acids which help strengthen brittle fingernails and support healthy nail growth. Other good sources of zinc include dairy products, shellfish, eggs, seaweed, beans and wholegrain cereals

4. Be mindful of B-vitamins 

B vitamins including Biotin, Folate, Vitamin B12 (cobalamin) & B6 are vital for cell functioning and promote healthy growth of nails, hair and skin.

Supplementation with biotin has been shown to contribute significantly to nail plate thickness, helping to prevent nail splitting and combat nail thinness. Vitamin B12 deficiency is associated with nail dryness, curved nail ends and darkening of fingernails.

B vitamins are found in a variety of foods such as wholegrains, egg yolks, sweet potato, nuts, seafood, meat, offal and spinach.

5. Ensure you’re getting enough Iron 

Iron is required for red blood cell production, to transport oxygen around the body - including your nails. Low Iron levels can lead to softening of your nail plate causing nails to become brittle, dry and fragile which can make them collapse inwards.

Getting sufficient Iron in your diet, as well as good intake of Vitamin C to help maximise absorption, can boost nail growth and help to prevent hangnail.
