REFOCUS contains 100% natural silica with added iron and vitamin D. Iron contributes to normal energy-yielding metabolism and normal cognitive function. Both iron and vitamin D contribute to the normal function of the immune system. Iron and Vitamin D deficiency is the most common in the world and especially in the nordic countries. That is what inspired us to develop the product. REFOCUS is registered at the vegan society and cruelty free. Get refocused and get on track with your routine with REFOCUS!
