The verdict

Same cheap-herb skeleton as the rest — D-AA, D3, zinc, magnesium, B6, fenugreek — plus oyster extract (which is really just more zinc). Fully disclosed, and graded on the real numbers only the vitamin D and boron hit their doses; everything else is a fraction of the studied amount. Nothing here justifies the price — the effective minerals are dirt cheap bought loose.
