“We trialled this in our New Zealand supermarkets last year and the reception from young women and parents in particular has been remarkable," said Woolworths Managing Director, Natalie Davis.
"Young women are especially passionate about reclaiming the word and calling periods what they are."
The change aims to destigmatise the category by calling the products what they are, rather than a euphemism, while also making it easier to find the products online and in store.
The company has also enlisted radio personality Ash London to help promote the change.
"I’m all for calling things the way they are - and for too long we’ve felt like we have to speak in code about one of the most natural things on the planet!" said Ash, who is an offical Period Care Ambassador.
"This may seem like a small step, but my hope is that it contributes to a future where young people especially feel less shame and embarrassment when it comes to periods."
The category includes products like pads, tampons and menstrual cups, with the new signage now visible across Woolworths digital platforms.
It will progressively continue to roll it out across all stores in Australia in the months ahead.
