Biotin has some research behind it for nails, and it’s the only supplement that made a visible difference for me. It took a few months of taking it daily though.
Peeling can also mean you need more than vitamins. Low iron is a common cause of weak nails, so make sure you’re getting enough iron and protein.
Nails grow slow, so give it three to six months before deciding if anything’s working. I take around 2,500 mcg of biotin.
Peeling is often mechanical damage from water exposure or using your nails as tools (more on that here). Gloves for dishes might help as much as any pill.
