Charitable organisations & partnerships
Our founders and team are committed to supporting others, beyond our high quality supplements, so you can feel good about choosing Optibac.
To date we have donated over £2,000,000 to charitable organisations around the world, giving at least 1% of our annual turnover to charity every year. Here's a flavour of the charities we support, including some of our most recent donations from 2025 and 2026:
We're very proud to have donated over £1.2 million to Womankind Worldwide (as of March 2026). Since launching our For Women supplement in 2014, we've contributed to this international women's rights organisation for every pack sold, supporting their work to end violence against women and girls, advance women's economic rights, and strengthen women's leadership worldwide.

Since 2011 we've supported the Patient Welfare Programme in Nairobi, Kenya, run by the Aga Khan University Hospital. Our donations have funded medical treatment, including cancer care, heart surgery and maternal health, for more than 1,125 adults and children who would otherwise be unable to afford it.

Our planet
Over the last few years we have moved our capsule supplements from plastic containers to glass jars. The cartons (which allow space for the important suitability & recommendation directions) housing the glass jars are made from fully recyclable cardboard cartons, and each jar comes with a metal lid which is also recyclable. Overall, we have reduced the plastic in our capsule supplements packaging by 96%.
Our most recently launched Kids Gummies and Gut Health Gummies come in completely plastic-free packaging, with a home-compostable pouch and recyclable outer carton.
Our commitment to sustainability extends to our packaging materials. Our delivery boxes are fully recyclable, made from 70% recycled materials and printed using water-based inks.
Not only do we consider the environment in our outwardly visible efforts, but the environment is always on our minds in the heart of the Optibac head office. It may seem small, but we all encourage each other to reuse and recycle our paper, turn off unused lights and computers, and boil no more water than necessary for the morning round of tea. We use the most sustainable suppliers possible, from plastic free point of sale materials in store, right down to our bamboo toilet paper at HQ!

We first won the Queen's Award in 2019 and are delighted to have been acknowledged yet again for our impressive international growth.
