The product uses generally well-regarded forms for its minerals, such as calcium citrate and amino acid chelates, which can support absorption. However, the horsetail extract does not specify its exact silica content or standardization.
The NOW Silica Complex is designed to provide comprehensive mineral support, primarily focusing on silica sourced from Horsetail extract. Silica is an important trace mineral often associated with the structural integrity of connective tissues, hair, skin, and nails. This product delivers a substantial 575mg of Horsetail extract, which serves as its main silica component.
Beyond silica, the complex includes several complementary minerals like Calcium (as Citrate), Zinc (as Amino Acid Chelate), Manganese (as Amino Acid Chelate), and Boron (as Amino Acid Chelate). These chelated forms are generally considered beneficial for absorption. This blend aims to work synergistically, supporting various aspects of general health, including bone density, joint flexibility, and hormonal balance.
The inclusion of multiple minerals alongside the primary silica source makes this a multi-faceted supplement for those looking for broad-spectrum support. It can be a convenient option for individuals seeking to bolster their intake of these specific trace minerals and silica within a single tablet form.
