What functions does vitamin D have in the body?
Vitamin D plays a key role in the body's health, particularly in relation to bone metabolism. It promotes the absorption of calcium and phosphate from the intestines, thus ensuring the development and maintenance of strong bones and teeth. Furthermore, vitamin D positively influences the immune system by contributing to the defense against pathogens. It also plays an important role in the regulation of cell growth and in the function of muscles and nerves.
• Vitamin D3 contributes to the maintenance of normal muscles and bones.*
• Vitamin D3 contributes to the normal function of the immune system.*
• Vitamin K2 contributes to normal blood clotting.*
Why do the vitamin D drops also contain vitamin K?
Vitamin K2 is combined with vitamin D3 in drops because the two vitamins complement each other in their effects – especially with regard to bone health and calcium metabolism.
Vitamin D3 increases calcium absorption in the intestines and ensures that more calcium enters the bloodstream. However, to ensure that this calcium is not deposited in the wrong places—such as in the arteries or soft tissues—but is incorporated specifically into the bones, the body needs vitamin K2. K2 activates certain proteins, such as osteocalcin, which deposits calcium in the bones, and matrix GLA protein, which prevents calcium deposits in the blood vessels.
In short: Vitamin D3 brings the calcium into the body, vitamin K2 ensures that it gets to the right place.
What makes our vitamin D3 and K2 drops so special?
What makes Inner Sparkle's vitamin D3 and K2 drops so special is their sophisticated combination of effectiveness, quality, and ease of use. Thanks to the practical pipette, the high-dose formula with 1,000 IU of vitamin D3 per drop is easy to dose. We use high-quality MCT oil as a carrier oil – it ensures optimal absorption of the fat-soluble vitamins. The vitamin K2 they contain is in the stable and particularly easily absorbed all-trans MK7 form. Especially in sun-poor regions like our latitudes, a supplemental supply of vitamin D3 is sensible – and with Inner Sparkle's vitamin D and K2 drops, it's simple, efficient, and maximally bioavailable.

Frequently asked questions:
Where is vitamin D obtained from?
Our vitamin D3 is derived from lichens, a natural, "symbiotic system" of fungi and algae, both of which are vegan.
What does Menaquinone MK-7 all-trans mean?
Menaquinone-7 (MK-7) is a particularly easily absorbed variant of vitamin K2. The term "all-trans" describes the special molecular structure of this active ingredient – it ensures that the body can optimally recognize and utilize the vitamin. This form is considered the most bioavailable version of vitamin K2.
Why does the drops contain MCT oil?
Vitamins D3 and K2 are fat-soluble vitamins and can only be optimally absorbed by the body when taken with a suitable fat carrier. For this purpose, we use MCT oil – a tasteless extract from coconut oil that is ideal as a carrier substance and effectively supports absorption in the body.
Are the drops also suitable for pregnant and breastfeeding women?
Yes, the vitamin D3 and K2 drops are also suitable during pregnancy and breastfeeding.
