Strong bones depend on more than calcium alone — they need the right vitamins to direct that calcium where it belongs.

vitamin K2 ensures that calcium goes straight to your bones, without this balance, calcium can end up in soft tissues like arteries instead, which is why pairing it with vitamin D3 makes biological sense. 

Biogena's Vitamin D3 & K2 1.000 I.U. capsules deliver a combination of 1,000 I.U. vitamin D3 + vitamin K2 in proven quality, cleverly combined with valuable flaxseed oil and lutein.

The K2 component uses K2VITAL®, a highly pure K2 vitamin raw material obtained from natural MK7, guaranteeing a particularly high purity of at least 99.7% — a patented, traceable raw material rather than a generic vitamin K blend. 

The formula is built on Biogena's clean-label standard: it's gluten-free, lactose-free, and well absorbed by the body, and made 100% free from artificial colors and flavors, titanium dioxide, GMOs, nanoparticles, and magnesium stearate.

Every batch is independently tested by the German LEFO Institute, with full lab certificates published for transparency, and production takes place in-house in Salzburg, certified according to FSSC 22000.
