VITAMINThorne
Thorne Vitamin D/K2 Liquid
General bone and cardiovascular health support, especially for those needing a liquid or lower maintenance dose.. Thorne delivers high-quality ingredients. The D3 dose is adequate for basic maintenance but low for optimization in many adults. The K2 (MK4) dose is too low to provide significant benefits, limiting the full potential of the D3/K2 synergy. This pulls the overall score down despite the premium brand and good concept.
7.5/10
VERY GOODA good quality product with excellent synergy, but the K2 dose is too low for significant impact.
