For healthy nails, several supplements may offer potential benefits:

1. Biotin (Vitamin B7): This water-soluble vitamin is often recommended for strengthening weak or brittle nails. Some studies have shown that biotin supplements can increase nail thickness and reduce brittleness, though more research is needed¹².
2. Vitamin E: There is some evidence that vitamin E might help with conditions like yellow nail syndrome and brittle nails³.
3. Collagen Peptides: Oral supplementation with specific bioactive collagen peptides has shown promising results in increasing nail growth rate and reducing the frequency of broken nails⁴.
4. Silicon: Supplementation with silicon, mainly in the form of choline-stabilized orthosilicic acid, has been noted to help with brittle nails⁵.

However, it's important to note that in individuals who are not deficient in these nutrients, supplementation may not provide significant benefits.
