Northampton Town are backing the On the Ball campaign, and baskets of free sanitary products have been installed in female and disabled toilets at the PTS Academy Stadium.
Chief Executive James Whiting said: "We are pleased to support the On the Ball campaign.
"We are an inclusive, community football club with a wide spectrum of support and we want to do what is right. We saw the On the Ball campaign and their belief that sanitary products should be accessible to all female supporters for no charge and we agree completely.
"We have therefore had these made available in the female and disabled toilets around the PTS Academy Stadium.
"It is a bit of a taboo subject but it really shouldn't be. More and more football clubs are getting behind the campaign and it is a shocking statistic that has been widely reported that a 2017 study showed that at some point, one in 10 teenage girls have been unable to afford sanitary products, while one in seven has had to borrow products. That is just wrong.
"We have a growing percentage of female supporters at our games and if this campaign helps just one of them then that is great."
