Our ingredient sourcing criteria

If we wouldn’t put it in our bodies, it won’t make it into our packs. We constantly challenge ourselves to formulate products that are tested and proven to be safe and effective. And it all starts with our high quality ingredients.

We scrutinise everything – sourcing strictly from suppliers we trust to provide potent, highly bioavailable ingredients. Sustainable and organic where possible. And no cheap fillers.

Our active ingredients are sourced and selected in collaboration with nutrition and health experts and backed by scientific research.

When you buy a Two Islands product, you can trust that every ingredient has been independently lab tested and verified for safety and efficacy. Ingredients at risk of being adulterated or fraudulent are also tested for authenticity – so you know what it says on the outside, is exactly what’s on the inside.

We're led by an evidence-based approach, where each product – and every ingredient – has a purpose. As the science of nutrition evolves, we're constantly learning too.
