Here are some nutrients commonly associated with nail health:Biotin ( Vitamin B7): This B vitamin supports keratin infrastructure. Some older studies have shown that higher biotin intake may help improve nail thickness and reduce brittleness in people with splitting issues.
Iron: Low iron levels are one of the more common nutritional factors tied to brittle nails, especially in women. It helps with oxygen delivery, which supports healthy nail growth.
Protein: Since nails are primarily protein, getting enough from your diet is essential for strong structure.
