It's the lower strength "Every Day" one. I've also recently tried one Boots do called Good Gut + women's health support. It's manufactured for them by a very reputable probiotics company. I can't yet vouch for the efficacy of any of these as my GU tract was so badly affected by the surgery & related antibiotics it's taken a long time to get the GSM back under control via multiple measures, so not sure what's helped most, but the vaginal HRT is an absolute must for me.
