Where Ellasie is different
4-strain Lactobacillus blend
Stronger daily serving
XOS prebiotic support
Synbiotic formula
What is a synbiotic?
A probiotic provides live beneficial bacteria. A prebiotic is a fibre that helps feed beneficial bacteria. A synbiotic combines both in one formula.
Ellasie Intimate Balance includes probiotic strains plus XOS prebiotic support. This is the key formula difference versus Optibac For Women, which lists probiotic strains but no added prebiotic in its official ingredient information.
Probiotic: live beneficial bacteria
Prebiotic: food source for beneficial bacteria
Synbiotic: probiotic plus prebiotic in one routine

-
"I've been through every probiotic Holland & Barrett sells. The synbiotic angle was new to me and I researched it before buying. I'm now five bottles in and this is the routine I've kept. The 90-day guarantee made it easy to try."
-
"I switched from Optibac because I wanted the prebiotic included. Honestly the routine is the same, but it feels more complete as it has prebiotic fibre in its formula."
-
"What I appreciated was the honesty on their site. Every other brand promises miracles or have "hired influencers" to talk about the product. Ellasie has real Doctors that review the products. I bought because of that, peace of mind"
-
"I'm a nurse and I researched the strains and the prebiotic before buying. The formula is solid. The price is fair for what's in it. Three bottles in and I'm not coming off this."
