Vitamins K2+D3 brings two fat-soluble vitamins together in one softgel, taken with a meal. Each has its own authorised claims in the EU. Here is what each vitamin is and why we do not add their effects together.

Vitamin D3: cholecalciferol

Vitamin D3 is cholecalciferol, the form of vitamin D the body produces in the skin with sunlight and that is also found in some foods. The label expresses it in two ways, in micrograms and in international units (IU): the same amount, stated twice.

It is a softgel designed to be taken on its own: the label says not to combine it with other vitamin D supplements without professional advice.

Vitamin K2: menaquinone

Vitamin K comes in two families: K1 (phylloquinone, found in green leaves) and K2 (menaquinones, of bacterial origin and present in fermented foods). Vitamins K2+D3 uses menaquinone.

Each vitamin, its own claims

With two vitamins in the same softgel it is tempting to add effects together, but the regulation does not allow it: each sentence is attributed to its nutrient and there is no authorised claim for the combination of K2 and D3. Bodyvibe quotes them separately and does not describe how they interact.

Why with a meal

Both vitamins are fat-soluble: they dissolve in fat, not in water. That is why the softgel carries them in olive oil and the label says to take it with a meal. Choosing the same meal every day, breakfast for instance, helps you remember. The shell is gelatine, glycerol and water: not suitable for vegans or vegetarians.

Who should check first

  • People on anticoagulant treatment: the label says to consult a doctor before taking this product.
  • Anyone already taking another vitamin D supplement: do not combine without professional advice.
  • Pregnancy, breastfeeding, medication or a medical condition: consult a health professional.

In short

  • One softgel a day, with a meal.
  • Each vitamin has its own claims; there is none for the combination.
  • Do not combine with other vitamin D supplements without professional advice.
  • Gelatine softgel: not suitable for vegans or vegetarians.
