Our bodies are able to recognise and absorb minerals more easily when they’re taken from natural and complete sources.
- FREE FROM OCEAN CONTAMINANTS: Our seaweed is harvested from the ocean, so we take steps during the manufacturing process to purify the seaweed before conducting industry-recognised testing. And reject any batches that don’t pass, of course.
- CLEAN, PURE, NATURALLY EFFECTIVE: At Together, we make products you can trust – and we’re proud of that. Our entire range is certified vegan and free from artificial additives and processing aids, so you only ever get the purest possible product.
