Keratin is a protein responsible for increasing the resistance of the hair, nails, and the outer layer of the skin. Even though there are no foods rich in Keratin, since it is not found in foods, consuming some foods rich in protein and some vitamins can boost the production of natural Keratin in the body, strengthening and improving the appearance of hair, skin and stimulating the growth of the nails.

Sulfurous Foods

Amino acids are the building blocks of proteins like Keratin, which is composed of sulfur-rich amino acids that come together to form a strong chain. Protein-rich foods such as meat, beans, and eggs, are good sources of sulfur. They can also be found in some vegetables such as onions, cabbage, asparagus, and Brussels sprouts.

Protein Foods

Eating foods high in protein gives the body the amino acids it needs to produce Keratin. Red meat, fish, chicken, pork, eggs, milk, and yogurt are protein foods. The best vegetable sources of protein include beans, nuts, and quinoa. Most adults need two to three servings of protein a day to meet their daily needs.

Biotin-rich Foods

Biotin is required to metabolize Keratin amino acids, and it is generally recommended for fortifying hair and nails. Dietary sources of biotin include nuts, beans, whole grains, cauliflower, and mushrooms. It can also be found in boiled egg yolk. Raw egg whites have a protein that interferes with the absorption of biotin. Because it is water soluble, biotin is not stored in the body and can be lost depending on the cooking methods like boiling.

Foods Rich In Vitamin A

Vitamin A is required for the synthesis of Keratin. Therefore, good dietary sources of Vitamin A can be considered foods rich in Keratin: fruits like orange and vegetables such as pumpkin, sweet potatoes, raw carrots, and melon. Baked green vegetables such as spinach and kale are also rich sources of Vitamin A. Vitamin A is fat soluble, so it can only be absorbed when ingested with a source of fat. This also means that excess intake of Vitamin A is stored in the body.

List Of Nutrient-rich Foods That Help In The Production Of Keratin

As we saw above, there are no foods rich in Keratin itself, but these below are good sources of the nutrients that boost the creation of this substance in our body. Check it out:
