Horsetail extract provides a natural source of silica, which is believed to assist in collagen cross-linking and the strengthening of the organic bone matrix. The inclusion of manganese and zinc further supports the enzymatic processes required for bone formation and density maintenance.

While this complex addresses several secondary pathways for bone health, the doses of primary structural minerals like calcium are minimal. It is best used as a supportive supplement for matrix quality rather than a primary driver of bone mineral density.
