Vitamin D3 and Vitamin K2 are included in this collagen-focused formula to support skeletal and connective tissue health. Vitamin D3 is an essential pro-hormone building block required for natural testosterone synthesis.

While the product provides high-quality marine collagen, its primary focus is not hormonal support. The 1000 IU dose of Vitamin D represents a standard maintenance level rather than a targeted therapeutic dose.

B- Goal FitC- Strength of SupportC- CoverageA- Formula Quality

This bone health supplement contains Calcium, Magnesium, and Vitamin D3 along with Marine Collagen and Vitamin K2. These ingredients aim to support structural tissue density and vascular flexibility.

The Marine Collagen dose is functionally insignificant for structural repair, and the K2 dose is slightly below optimal clinical ranges. It provides modest support for skeletal aging but lacks the potency found in more concentrated formulas.
