Why do we need the combination of Vitamin D3 and K2?

Vitamin D is essential for the maintenance of bones and teeth, muscle function, and the immune system, as well as normal cell division. It works closely with Vitamin K: Vitamin D3 stimulates the production of osteocalcin, which is activated by Vitamin K2 to efficiently deposit calcium in the bones.

Vitamin K2 is hardly absorbed through diet. Dr. Jacob’s Vitamin D3K2 Oil contains long-chain Vitamin K2 (menaquinone-7) with high bioavailability and stability. It remains in the body for up to three days, about 50 times longer than Vitamin K1.

Only 12% have good Vitamin D3 levels, in winter less than 5%

Diet contributes little to Vitamin D supply; crucial is UVB sunlight for the body's own synthesis in the skin. A deficiency is particularly common in winter, but even in summer, factors such as sunscreen or a dark skin type can inhibit Vitamin D synthesis. Studies show that self-production is often insufficient even in summer:

• Only 12% of the German population achieve the Vitamin D level recommended by leading scientists of over 75 nmol/l on average throughout the year, and less than 5% in winter.
• Only 38% of Germans reach the lower threshold value of the German Nutrition Society (DGE) of at least 50 nmol/l throughout the year.

Experts also disagree on the correct intake recommendations. In fact, this depends on many factors: baseline level, age, weight, sun exposure, skin color, etc. The DGE recommends a serum level of at least 50 nmol/l and a daily intake of 800 IU (20 µg) Vitamin D (from the age of 2 years, if own synthesis is insufficient).

The renowned American Geriatrics Society recommends a daily intake of 4000 IU (100 μg) of Vitamin D (from all sources) for all people over the age of 70 to maintain a good serum level of at least 75 nmol/l. This corresponds to the daily intake set as safe (tolerable) by the European Food Safety Authority (EFSA) for people aged 11 and older.

Who should especially pay attention to their Vitamin D levels?

• Everyone during months with low UV radiation (October to March)
• People who spend most of their time indoors or cover their skin
• Users of sunscreen (SPF 10 reduces Vitamin D production by 90%)
• People with dark skin types
• Pregnant women, breastfeeding mothers, babies, and young children
• Women in/post-menopause
• Overweight individuals
• Seniors

A Vitamin D blood test (at the doctor, pharmacy, or online) provides clarity.

Vitamin D3K2 Drops – for Bones and Immune Defense*

*The vitamins in Dr. Jacob’s Vitamin D3K2 Oil contribute to the following normal body functions:

• Maintenance of bones – Vitamin D and K
• Maintenance of teeth – Vitamin D
• Maintenance of muscle function – Vitamin D
• Immune system – Vitamin D
• Normal cell division – Vitamin D
• Normal absorption and utilization of calcium – Vitamin D
• Normal blood clotting – Vitamin K
• Reduction of fall risk** – Vitamin D

**In women and men over 60, falls are a risk factor for bone fractures. This increased fall risk in old age may be related to Vitamin D supply. The daily intake of 800 IU (20 µg) of Vitamin D (from all sources) in people over 60 years of age leads to a reduction in the risk of falls associated with muscle weakness and physical instability.

Proven quality at a fair price

As early as 2015, Dr. Jacob’s was the first manufacturer to bring a Vitamin D3K2 Oil to German pharmacies. To this day, Dr. Jacob’s Vitamin D3K2 Oil is manufactured in Germany. The vitamins used are of pharmaceutical quality and come from Europe. Regular analyses confirm the long-term stability of the vitamin content.

One bottle contains 640 servings. 1 serving corresponds to one drop with 20 μg (800 IU) D3 + 20 μg K2 (all-trans MK-7).

MCT oil for optimal protection and better absorption

To improve the absorption of the fat-soluble vitamins D3 and K2, we use a high-quality MCT oil made from coconut oil in Europe. Together with the natural Vitamin E family (tocopherols), this oil protects the sensitive fat-soluble vitamins and optimizes their absorption.

Dr. Jacob’s Vitamin Oils are easy to use, ideal for people with swallowing difficulties, and particularly child-friendly. They come in glass bottles with glass pipettes for precise dosing.

Best synergy: The ideal partners of Vitamin D

Not only does Vitamin D3 contribute to the maintenance of normal bones, but so does Vitamin K2. Both work synergistically and should ideally be taken together, as in Dr. Jacob’s Vitamin D3K2 Oil, Dr. Jacob’s Vitamin D3K2 Oil forte, Dr. Jacob’s Vitamin K2D3 Oil (for increased Vitamin K2 needs), and Dr. Jacob’s Vitamin DEKA Oil (with Vitamin A and E as natural tocopherols).

The calcium metabolism is closely linked with magnesium and potassium. Calcium and magnesium contribute to the maintenance of normal bones. Magnesium and potassium support the normal function of nerves and muscles, and potassium helps maintain normal blood pressure. According to NVS2, a deficiency in these minerals is common. Therefore, Vitamins D3 and K2 should ideally be combined with the right minerals, such as in Dr. Jacob’s Alkaline Powder.

Recommended intake:

For adults and children aged 1 year and older: 1 drop daily (1 serving). (For increased needs up to 5 drops) Babies under 1 year: 1 drop every other day.

1 drop contains 20 µg of Vitamin K2 (as all-trans MK-7) and 20 µg of Vitamin D3 (800 IU).

Note: If taking Vitamin K antagonists (coumarin-type blood thinners), consult a doctor before use!

Legal notice: The recommended daily intake should not be exceeded. Keep out of reach of small children. Dietary supplements should not be used as a substitute for a balanced, varied diet and healthy lifestyle.

Ingredients: MCT oil (medium-chain triglycerides from coconut oil), antioxidant rich in tocopherols (Vitamin E of natural origin), Vitamin D3, Vitamin K2 (menaquinone, all-trans MK-7). Vegetarian.

As of 13.08.2024

Origin of all ingredients is the EU. The Vitamin D3 used is obtained by UV light irradiation of lanolin (wool wax), which is sourced from the wool of live sheep. Approximately 0.02 g of lanolin is used per bottle of Vitamin D3K2 Oil for Vitamin D production.
