Vitamin D3 K2 Drops with K2VITAL® - 1000 IU D3 + 30 µg K2 + Vitamin E | 30 ml

Vitamin D3 and K2 - two fat-soluble vitamins as a duo

  • Vitamin D3 (cholecalciferol) belongs to the group of fat-soluble secosteroids. The body can produce it in the skin under UVB radiation - however, in Central Europe the sunlight from October to March is often not sufficient for this.
  • Vitamin K2 comprises the menaquinones (MK-4 to MK-13). Menaquinone-7 (MK-7), with seven isoprene units in its side chain, is the form most commonly used in food supplements - in nature it occurs mainly in the fermented soy product natto.
  • Both vitamins are fat-soluble. In Green Naturals Vitamin D3 + K2 they are therefore dissolved in MCT oil (medium-chain triglycerides from coconut) - a drop format that allows precise dosing.

K2VITAL® - vitamin K2 MK-7 with min. 99.7 % all-trans

  • Green Naturals Vitamin D3 K2 drops contain the branded ingredient K2VITAL® with a min. 99.7 % all-trans content - in contrast to many manufacturers who declare vitamin K2 without stating its form or isomeric purity.
  • Only the all-trans form of MK-7 corresponds to the natural molecular structure; cis isomers are considered to be significantly less biologically active. This is why "min. 99.7 % all-trans" is stated directly in the ingredients list.
  • The synthetically produced MK-7 in K2VITAL® was investigated for bioavailability in a randomised cross-over study in comparison with fermentation-derived MK-7 (Møller et al., 2016); the uptake of MK-7 compared with MK-4 was also investigated in healthy women (Sato et al., 2012).

Vitamin D3 + K2 with vitamin E - proven benefits

  • Vitamin D and vitamin K contribute to the maintenance of normal bones. Vitamin D also contributes to the normal function of the immune system, to the maintenance of normal muscle function and to normal blood calcium levels (authorised EFSA claims).
  • One drop provides 1000 IU (25 µg) vitamin D3 (500 % NRV), 30 µg vitamin K2 (40 % NRV) and 1.8 mg vitamin E (15 % NRV) - vitamin E contributes to the protection of cells from oxidative stress.
  • 30 ml contain approx. 1020 drops - at 1 drop daily, one bottle lasts around 1020 days, i.e. approx. 34 months.

Vitamin D3 K2 Drops with K2VITAL® - 1000 IU D3 + 30 µg K2 + Vitamin E | 30 ml

  • Optimal time of intake

    Take 1 drop once daily, ideally with a meal - vitamins D and K are fat-soluble. Shake the bottle before each use; regular daily intake is more important than the time of day.

  • Dosage and duration of use

    Daily dose: 1 drop (= 1000 IU or 25 µg vitamin D3, 30 µg vitamin K2 as K2VITAL® and 1.8 mg vitamin E). The 30 ml bottle contains approx. 1020 drops and therefore lasts approx. 34 months. For adults only. Pregnant and breastfeeding women and children should ask a doctor or pharmacist before use; anyone taking anticoagulants (blood thinners) should seek medical advice before taking vitamin K supplements.

What is vitamin D3 K2?

Vitamin D3 K2 refers to the combination of two fat-soluble vitamins: vitamin D3 (cholecalciferol) and vitamin K2, usually in the form of menaquinone-7 (MK-7). Green Naturals Vitamin D3 + K2 provides 1000 IU vitamin D3 and 30 µg vitamin K2 as the branded ingredient K2VITAL® per drop, complemented by 1.8 mg vitamin E. The vitamins are dissolved in MCT oil from coconut.

What are vitamin D3 and K2 good for?

According to the authorised EFSA claims, vitamin D and vitamin K contribute to the maintenance of normal bones. Vitamin D also contributes to the normal function of the immune system, to the maintenance of normal muscle function and to normal blood calcium levels. The vitamin E it contains contributes to the protection of cells from oxidative stress.

Why take vitamin D with K2?

Both vitamins are involved in bone metabolism: vitamin D and vitamin K contribute to the maintenance of normal bones, and vitamin D also contributes to normal blood calcium levels. Because both are fat-soluble, they can be conveniently combined in one oil - so a single drop covers both nutrients.

Do you have to take vitamin D with K2?

No, there is no requirement to combine them - vitamin D can also be taken on its own. Many users prefer the combination because vitamin D and vitamin K contribute to the maintenance of normal bones and both can be combined in one drop formula. If you take anticoagulants, you should only use vitamin K supplements after consulting your doctor.

How much vitamin D3 K2 per day?

The recommended daily dose is 1 drop. It provides 1000 IU (25 µg) vitamin D3, which is 500 % of the nutrient reference value (NRV), as well as 30 µg vitamin K2 (40 % NRV) and 1.8 mg vitamin E (15 % NRV). Do not exceed the stated recommended daily intake.

When should you take vitamin D3 K2?

You can choose the time of day freely - what matters is regular daily intake. As vitamins D and K are fat-soluble, it makes sense to take them with a meal, for example with breakfast or lunch. This also makes it easy to build the drop into your daily routine.

How do you take vitamin D3 K2 drops?

Shake the bottle before use and place 1 drop once daily on a spoon or directly onto food, for example a piece of bread or a yoghurt. The drop can also be placed directly on the tongue. Afterwards, store the bottle upright, dry, protected from light and below 25 °C.

Can you overdose on vitamin D3 K2?

Vitamin D is fat-soluble and is stored in the body, so the recommended daily dose of 1 drop should not be exceeded. If you also take other products containing vitamin D, add up the amounts and, if in doubt, discuss this with your doctor or pharmacist. One drop of Green Naturals Vitamin D3 + K2 contains 1000 IU vitamin D3.

What is K2VITAL®?

K2VITAL® is a branded ingredient for vitamin K2 in the form of menaquinone-7 (MK-7) with a min. 99.7 % all-trans content - the form that corresponds to the natural molecular structure. K2VITAL® is a trademark of Balchem Corporation. The bioavailability of the synthetically produced MK-7 was investigated in comparison with fermentation-derived MK-7 in a randomised study (Møller et al., 2016).

Is the product vegan?

No, Green Naturals Vitamin D3 + K2 is vegetarian, not vegan. MCT oil from coconut, vitamin K2 (K2VITAL®) and vitamin E contain no animal components; however, vegetarian-grade vitamin D3 is usually obtained from lanolin (wool wax from sheep). The product is therefore labelled "Vegetarian".

Is the product completely natural?

The formula is deliberately lean and needs only 4 ingredients: MCT oil from coconut as the carrier oil, vitamin K2 MK-7 (K2VITAL®), vitamin E (D-α-tocopheryl acetate) and vitamin D3 (cholecalciferol). The MK-7 in K2VITAL® is nature-identical but synthetically produced. We completely avoid colourants, added flavourings and magnesium stearate.

Is the product suitable for children and pregnant women?

Green Naturals Vitamin D3 + K2 is intended for adults. Pregnant and breastfeeding women and children should consult a doctor or pharmacist before use. People taking anticoagulants (coumarin-type blood thinners) should seek medical advice before taking vitamin K supplements.

How long does one bottle last?

One bottle contains 30 ml, i.e. approx. 1020 drops. At the recommended intake of 1 drop daily, it lasts around 1020 days - that is approx. 34 months. Please store the bottle upright, dry, protected from light and below 25 °C.

Are vitamin D3 K2 drops available in pharmacies?

Yes, Green Naturals® Vitamin D3 + K2 is available in German pharmacies under the PZN 20185131 (German pharmacy number) and also via online pharmacies. Alternatively, you can order the drops directly from the Green Naturals online shop. The PZN helps your pharmacist find exactly this product quickly.
