Sports Research discloses individual doses for 2 of its 3 active ingredients in this vitamin D3 and K2 capsule, placing it in the excellent transparency band. Of the 2 ingredients that could be assessed against amounts used in published research, none sit below those amounts. Worth noting: the transparency band reflects how much a brand tells you, not a judgement on dose strength itself. The full ingredient-by-ingredient verdict, score and alternatives are in the complete report.
