Keratin Supplements
Many industries add keratin or vitamin supplementations to help promote keratin production and improve or maintain nail, skin, and hair health. The beauty industry especially promotes keratin as an option to prevent damage to hair. Keratin supplements can be easily purchased at most health food stores. They are available in capsule and powder forms. Make sure to be aware of possible risks and side effects. When used excessively, they may lead to the accumulation of proteins in the body. [8]
Nutrients Aiding In Keratin Production
Some nutrients may aid in the production of keratin in the body. Also, they might help improve your skin, nail, and hair health. You can consume products with the following nutrients to help produce keratin: biotin, L-cysteine, zinc, vitamin C, as well as vitamin A. They can be found in many foods, drinks, and supplements. [9]
Possible Risks
There is no evidence of damage caused by keratin to your nails, skin, or hair. However, some chemicals added to keratin during hair treatments may cause possible adverse effects. For instance, using formaldehyde may result in some health problems, such as hair damage and loss, mood changes, scalp irritation, itchy skin, allergies, throat, and nose irritation, or stinging and itching eyes.
