MSPs agree the general principles of the Period Products (Free Provision) (Scotland) Bill, with 112 backing it and just one abstention.
The member's bill, put forward by Labour MSP Monica Lennon, will make period products available to all free of charge.
The Scottish government changed its position last week and pledged to support the bill.
At present tampons, pads and some reusable products are funded in schools, colleges and universities.
That abstention came from James Dornan, the Local Government and Communities Committee convener, following the Stage One report not backing the general principles.
