It is a well-known fact that good nutrition plays a major role in determining how we feel on the inside and how we look on the outside. One such mineral, silica, is essential for the building and repair of healthy connective tissues. Traces of this mineral can be found in every organ and cell of the body, with its greatest concentrations being in cartilage, blood vessels, skin and hair. Nu-Sourceâ„¢ Naturals Nu-Beautyâ„¢ is an herbal formula for skin, nail and hair care. It contains naturally occurring silica from horsetail, reinforced with cruciferous vegetables and Hawaiian spirulina to help detoxify the body.
