What is Optibac?

Optibac Probiotics is a UK and Ireland brand specialising entirely in friendly bacteria supplements. Founded in 2004 and based in the UK, Optibac has built one of the most extensive research-backed ranges of live culture supplements available in the Irish market. The brand's range has more published clinical research behind its strains than any other leading friendly bacteria brand in the UK and Ireland.

Optibac does not take a one-size-fits-all approach. Each product in the range is formulated around specific strains of live cultures that have been selected and researched for different groups of people and different life stages — including daily general use, women's intimate health, pregnancy, travel, antibiotic use, children, and babies from birth.

The range is regulated in Ireland as food supplements under the European Communities (Food Supplements) Regulations 2003 and the Food Supplements Regulations 2022, enforced by the FSAI (Food Safety Authority of Ireland).

About Optibac as a Brand

Optibac Probiotics was founded in 2004 and is based in the UK. The company was built around the principle that strain specificity matters — that different types of friendly bacteria have different properties, and that people deserve supplements formulated around published research rather than generic high-dose blends.

The brand has donated over £2,000,000 to charitable organisations worldwide, donating at least 1% of annual turnover to causes including the Aga Khan University Hospital's Patient Welfare Programme in Nairobi, Womankind Worldwide (over £1.2 million donated as of March 2026), ABCD Bethlehem, Gecko, and EDP Trust in Ghana. For every pack of For Women sold, a contribution is made to Womankind Worldwide, which focuses on ending violence against women, advancing women's economic rights, and strengthening women's participation and leadership globally.

On sustainability, Optibac has reduced the plastic in its capsule supplement packaging by 96%, moving from plastic containers to glass jars in FSC-certified cardboard cartons. Its newest gummy products come in fully home-compostable pouches.
