Question: 1 / 400

Which ingredient in nail products helps in toughening the nail plate?

Calcium

Calcium is an essential mineral that plays a crucial role in maintaining the strength and structure of the nail plate. It contributes to the hardness and durability of nails, making them more resistant to breakage and damage. When incorporated into nail products, calcium helps to reinforce the natural composition of the nails, promoting healthier and tougher nails over time.

Protein, while important for overall nail health, primarily supports nail growth and structure rather than directly toughening the nail. Collagen is more associated with skin health and elasticity than with nail toughness. Silica can aid in strengthening nails to some extent but is not as directly related to toughening the nail plate as calcium. Thus, calcium stands out as the ingredient specifically known for its role in hardening and strengthening the nail plate.
