Nature's Answer Vitamin D3 & K2 Drops (15 ml) combines 25 mcg of vitamin D3 and 120 mcg of vitamin K2 (as menaquinone-4) per 2-drop serving. The formula is dissolved in olive oil and enriched with rosemary extract and natural lemon flavour. Vitamin D3 is sourced from lanolin, while vitamin K2 is provided in the form of menaquinone-4 (MK-4). Thanks to the liquid form, dosing is easy to measure. With 250 servings per bottle, this is a practical choice for daily use.
Vitamin D is naturally found in foods such as oily fish, liver, egg yolks, and fish oil. In addition, vitamin D is often added to food supplements and fortified foods.
The main difference lies in the source. Vitamin D2 (ergocalciferol) is usually derived from yeasts or mushrooms, while vitamin D3 (cholecalciferol) typically comes from lanolin, a natural substance from sheep's wool. In this product, vitamin D3 from lanolin is used.
Vitamin K is naturally found in various foods. Green leafy vegetables mainly contain vitamin K1, while vitamin K2 is found in certain fermented foods and animal products.
Vitamin K1 (phylloquinone) mainly occurs in green leafy vegetables. Vitamin K2 (menaquinone) is mainly found in fermented foods and is available in various forms, such as MK-4 and MK-7. This product contains vitamin K2 as menaquinone-4 (MK-4).
Vitamin D3 and vitamin K2 are fat-soluble vitamins. That's why they are often processed in an oil base, such as olive oil, to create a stable and easy-to-dose liquid formula.
