Who is NoordCode Ultimate D3+K2 for?

NoordCode Ultimate D3+K2 was developed to supplement the fat-soluble vitamins D3 and K2.

Ultimate D3+K2 is ideal if you:

• want to maintain your vitamin D level during periods of low sun exposure.
• want a more varied intake of vitamin K and prefer not to eat natto or liver (natural sources of vitamin K2).
• are looking for a combination supplement with D3 and K2 in scientifically backed forms and ratios.
• prefer a liquid supplement you can dose yourself instead of taking capsules.
• want a supplement in cold-pressed extra virgin olive oil, protected against light and oxidation.

The synergy of vitamins D and K for bones

Vitamins D and K work together to support strong bones. Vitamin D supports the absorption of calcium and phosphorus from food and helps maintain normal calcium levels in the blood. Both vitamin D and vitamin K contribute to the incorporation of calcium into bones. Together, these vitamins help ensure that the calcium from your diet ends up in your bones.

In addition, vitamin K supports proper blood clotting.

Vitamin D also has several other functions, including:

• contributing to strong teeth.
• supporting the process of cell renewal.
• helping maintain normal functioning of the immune system.
• supporting normal muscle function.
• helping to reduce the risk of falling, related to postural instability and muscle weakness.
  Falling is a risk factor for bone fractures in men and women over 60 years of age. This beneficial effect is obtained with a daily intake of 20 mcg of vitamin D from all sources.

Optimal ratios of vitamins D and K

NoordCode Ultimate D3+K2 contains vitamins D and K in ratios recommended by nutritional scientists based on scientific research.

The recommended serving of 4 drops provides:

• 75 mcg vitamin D3 as cholecalciferol (3,000 IU) (1500% RI*)
• 200 mcg vitamin K2 (267% RI*) of which:
  • 100 mcg menatetrenone / menaquinone-4 (MK-4)
  • 100 mcg menaquinone-7 (MK-7)

The included dropper allows for easy and flexible dosing based on individual needs.

* RI = Reference Intake

Vitamin D supplements as a complement to sun exposure

The sun is the best natural source of vitamin D. When exposed to direct sunlight, your skin produces vitamin D. In north-western Europe, only the summer sun is strong enough for this.

We also spend more time indoors and protect ourselves against direct sunlight when outside. If you have darker skin or are older, you need more time in the sun to make enough vitamin D. A supplement can help maintain adequate vitamin D levels.

It is recommended to consult your GP and get your blood levels tested before and during supplementation. This allows you to tailor the dosage to your personal needs.

75 mcg vitamin D3 cholecalciferol from lanolin

Vitamin D3 (cholecalciferol) is the natural form your body makes. It is well absorbed and utilised when taken via food or supplements. The Dutch government sets the maximum safe daily intake of vitamin D from supplements at 75 mcg or 3,000 international units (IU).

Ultimate D3+K2 contains vitamin D3 from lanolin, a natural wax from shorn sheep's wool. Sheep must be shorn regularly to keep their fleece healthy. This makes lanolin a sustainable and popular source of vitamin D3. This form of vitamin D is suitable for vegetarians, but not for vegans.

Vitamin K2 for a more varied intake

Vitamin K exists in several forms in food. Vegetables and fruit mainly contain vitamin K1 (phylloquinone). Animal products such as (duck) liver, dairy, and eggs provide vitamin K2 as menaquinone-4 (MK-4). Bacteria produce menaquinone-7 (MK-7), which is mainly found in fermented foods such as sauerkraut, kimchi, aged cheese, and natto. Natto (fermented soybeans) is by far the richest source of vitamin K2, but it is not commonly eaten outside Japan.

The importance of varied vitamin K intake

Each form can fulfil all the functions of vitamin K. However, they differ in how they are processed and how long they remain active in the body. Vitamin K1 and MK-7 mainly work in the liver and bones, where they play a role in blood clotting and bone formation. MK-7 remains measurable in the blood longer than vitamin K1.

MK-4 is more available to the rest of the body. It quickly disappears from the blood because it is absorbed by various tissues shortly after digestion.

Due to the different properties of the various forms of vitamin K, it is advisable to ensure a varied intake. In Western diets, MK-4 and MK-7 are likely to be the least consumed. For those seeking a broad intake of vitamin K, a supplement provides an easy solution.

200 mcg vitamin K2

NoordCode Ultimate D3+K2 contains MK-4 and MK-7 in a 1:1 ratio. This provides fast-acting MK-4 that spreads throughout the body and MK-7 with longer activity in the liver and bones.

No maximum daily dose has been established for vitamin K. A dose of 200 mcg corresponds with what you could obtain from a healthy diet.

100 mcg MenaQ7® natural all-trans MK-7

NoordCode Ultimate D3+K2 provides 100 mcg of MenaQ7® MK-7. MenaQ7® is derived from soy-free bacterial fermentation and purified to 97% vitamin K2. Of this, 99.8% is in the all-trans MK-7 form. The all-trans configuration is the natural and active form of MK-7.

MenaQ7® is produced in Europe according to Good Manufacturing Practices (GMP) and has been tested in 22 clinical studies. It is a high-quality, highly pure and validated ingredient.

100 mcg Vitamin K2 MK-4

NoordCode Ultimate D3+K2 provides 100 mcg MK-4 per serving, from synthetic origin. Unlike MK-7, natural MK-4 cannot be produced on a large scale. Extraction from animal products is expensive and not common in supplement production. Synthesised MK-4 is stable and can be mass-produced, making it the standard form in supplements, including NoordCode Ultimate D3+K2.

Packaged for protection against light and oxidation

Vitamins D and K are fat-soluble, and NoordCode Ultimate D3+K2 therefore uses cold-pressed extra virgin olive oil as a carrier. Olive oil supports vitamin absorption better than other common carrier oils like MCT oil.

Rosemary oil is added as an antioxidant. The brown glass bottle protects the light-sensitive vitamin K and extra virgin olive oil from direct light. These measures help preserve the quality of the vitamins and fats.

NZVT certified doping-free

NoordCode Ultimate D3+K2 is certified by NZVT, the Dutch Anti-Doping Authority's Nutrition Supplement Assurance System. Every batch is tested for the (accidental) presence of doping substances. Supplements with NZVT certification are guaranteed to be free of doping substances, making them safe for professional athletes.
