Analysis

This tablet offers a broad spectrum of minerals that work together to support your whole musculoskeletal system. It uses magnesium aspartate and calcium citrate for better absorption than standard versions.

The inclusion of manganese and copper is a smart touch because these are often overlooked but are essential for bone matrix health. It is a very good value for the price, especially considering the extra trace minerals included.

Pros

  • Includes bone-supporting trace minerals
  • Uses bioavailable citrate and aspartate forms
  • Great value for a large supply

Cons

  • Uses Vitamin D2 instead of the more common D3
  • Contains magnesium oxide in the blend

Warnings

  • Zinc and copper should be kept in balance; this formula does that
  • Large serving size requires taking multiple tablets
