Natural Path Silver Wings has released a new vertical spray to its Colloidal Silver 250ppm (parts per million) enhanced strength product line. The spray requires fewer doses and absorbs quickly, the company says. This stronger 250ppm liquid formula naturally has an amber color (the higher the ppm, the darker the amber color). It is non-GMO, gluten-free, allergen-free, and made with zero chemicals. The company says the convenient 1-oz vertical pump spray bottle is safe and easy to administer on the go.
