    We respect our customers’ rights to, and demand for, products that work and are safe – we choose proven dosages and clinically-proven ingredients, which work to reduce allergens while aiming to be 100% gluten free and non-GMO.

    We follow the highest Health Canada standards for formulation, testing, labelling, and marketing – so our customers know the content and value of every Sisu product.

    Our premium, signature packaging includes recyclable tin lids and cobalt-blue glass bottles that are 100% recyclable, pharmaceutical grade, non-leaching glass to reduce oxygen, moisture, and light exposure and protect the product within.

    Our day-to-day actions enforce our reduce-and-reuse beliefs by eliminating air shipping, using recycled paper packing materials, office paper made from renewable sugar cane instead of virgin wood, and by participating in local recycling programs for paper, plastics, metal, organics, and more.
