Vitamin D3+K1+K2 Forte – a unique combination of high-dose vitamin D3 and vitamin K in 2 forms
Does it make sense to take vitamin D and vitamin K together as a food supplement?

Our bodies can produce vitamin D, but they need sufficient UV radiation from sunlight to do so.1 However, in Europe, sunlight may be insufficient for vitamin D synthesis for much of the year outside summer. We can also obtain vitamin D through our everyday diet. Its main sources include oily sea fish, eggs and foods specifically fortified (enriched) with vitamin D.2 Despite this, up to 40 % of the European population have insufficient blood levels of vitamin D.3

Vitamin K occurs in our diet in two main forms. Vitamin K1 (phylloquinone) is relatively abundant in leafy and cruciferous vegetables, such as spinach, kale and broccoli. Vitamin K2 (menaquinone), on the other hand, occurs naturally mainly in fermented foods, such as Japanese natto and certain aged cheeses, which are not usually a regular part of European diets.4 Even with an otherwise varied and balanced diet, there is therefore a risk that vitamin K2 intake may be insufficient.

But why take vitamins D and K together? Vitamin D supports calcium absorption into the blood, but an adequate intake of vitamin K is also needed to direct it properly into the bones. This is why vitamin D and vitamin K are often discussed together in scientific literature as nutrients that complement each other in calcium metabolism.5,6,7

For those who are unsure whether they get enough of both vitamins and want to maximise support for bone health, Vitamin D3+K1+K2 Forte is the clear choice.

Vitamin D3+K1+K2 Forte GymBeam: 4 features we focused on during development that set it apart from the competition

1. An effective form of vitamin D3 combined with two forms of vitamin K

Vitamin D is found in everyday foods and food supplements as animal-derived cholecalciferol (D3) and plant-derived ergocalciferol (D2). Studies conclude that our bodies convert cholecalciferol into the active form of vitamin D more efficiently than ergocalciferol.8 This is why we chose this form for our product.

Both vitamin D and vitamin K are lipophilic, meaning fat-soluble vitamins. For optimal absorption, it is advisable to take them alongside fats.9 This is why we put the vitamins in a softgel capsule containing a small amount of sunflower oil to help their absorption.

2. Two forms of vitamin K – phylloquinone and menaquinone to cover the full range of benefits

EFSA (European Food Safety Authority), an authority on human nutrition, treats vitamin K as a single substance and does not distinguish between a dietary intake consisting mainly of vitamin K1 or K2, because it has not yet been demonstrated that an adequate intake of just one form would fail to support all the functions of vitamin K in the body. However, a closer look at their metabolism shows that the two forms behave slightly differently.10

Phylloquinone has a short biological half-life, and the body preferentially uses it immediately in the liver to produce factors that contribute to normal blood clotting. Menaquinone, on the other hand, leaves the bloodstream more slowly and reaches tissues outside the liver, such as bones, to a greater extent. Some studies suggest that menaquinone (K2) activates osteocalcin, a protein essential for depositing calcium in bones, more effectively than phylloquinone (K1). However, EFSA states that the available data are not yet sufficient to attribute different effects on various aspects of health to the two forms of vitamin K.10 This is precisely why Vitamin D3+K1+K2 Forte combines both forms of vitamin K, covering both its role in blood clotting and its contribution to maintaining normal bones, regardless of which form contributes more.

Vitamin K2 is also provided in the premium chemical form of menaquinone-7 (MK-7) as the all-trans isomer. The cis-menaquinone-7 isomer is not present in the product at all.

3. An effective and safe dose of both vitamin D3 and vitamin K

For vitamin D3, we chose a dose of 100 µg (4000 IU), providing 2000 % of the nutrient reference value (NRV). This dose also corresponds to the upper limit for safe long-term daily intake for a healthy adult, as currently established by EFSA (European Food Safety Authority).11 In general, this is therefore the highest dose suitable for long-term use, provided you are not also consuming vitamin D from other dietary sources or food supplements.

Tip: If you are unsure about your vitamin D dosage, we recommend having a laboratory test to measure your blood vitamin D 25(OH)D level. You can then work with a doctor or dietitian to determine the ideal vitamin D dose tailored to you.

A daily dose of 200 µg of vitamin K, providing 267 % of the NRV, safely covers the recommended daily intake (100 % = 75 µg). No upper limit for safe long-term daily intake has been established for vitamin K. Available data have not demonstrated adverse effects in healthy adults even at high intakes (up to 10 mg daily for 1 month).10 An exception is people taking medicines that affect blood clotting. You can read more about this in the Dosage and Use section.

4. Quality and safety under third-party supervision

The product is tested by an independent laboratory for its active ingredient content: vitamins D3, K1 and K2. Safety testing, including microbiological and heavy metal screening, is also an integral part of the process. Our results for Vitamin D3+K1+K2 Forte GymBeam are openly available in the “Laboratory Tests” section.

Why does the body need vitamin D and vitamin K?

Although vitamin D and vitamin K are currently being studied in relation to many aspects of human health, we do not want to make any claims that lack reliable scientific evidence. We therefore list only officially authorised health claims.12

1. Immune system

Vitamin D supports the normal function of the immune system. This makes it one of the most closely monitored micronutrients, especially during the colder months when the body faces greater exposure to bacteria and viruses.

2. Absorption and utilisation of calcium and phosphorus

Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus. These are essential components of the structure of bones and teeth.

3. Healthy bones and teeth

Vitamin D contributes to maintaining healthy bones and teeth, while vitamin K contributes to maintaining healthy bones. This is valuable for growing children, people recovering from illness, athletes and older adults.

4. Cell division

Vitamin D also plays a role in cell division, a process essential for maintaining the function of cells, tissues and organs. This process continues throughout life and is crucial for maintaining health.

5. Muscle function

Vitamin D contributes to maintaining normal muscle function. This is important for all athletes and active older adults, for example.

6. Blood clotting

Vitamin K contributes to normal blood clotting, the natural process by which the body stops bleeding.

Why does the body need vitamin D and vitamin K?

Who is Vitamin D3+K1+K2 Forte suitable for?

1. People who do not regularly eat fermented foods or oily sea fish. The main natural sources of vitamin K2, such as natto or certain matured cheeses, and oily fish rich in vitamin D are not typically part of most people's regular diet in Europe.

2. Athletes and active people, because vitamin D plays a role in normal muscle function and calcium metabolism. Vitamins D and K also contribute to maintaining healthy bones, all of which have a significant impact on sports performance.

3. People who prioritise bone health. Vitamin D and vitamin K are among the nutrients with a proven effect on bone health. Women going through menopause and older adults should therefore pay particular attention to ensuring an adequate intake.

4. People with limited sun exposure over the long term. Office work, city living and shift work can all limit sun exposure. Just because it is summer and the sun is shining all day does not automatically mean your vitamin D levels are adequate if you actually spend most of the day indoors. To get the clearest picture of your health, we recommend having your vitamin D levels tested and, if you are deficient, taking appropriate supplements even during the summer months.

5. People on a weight-loss diet or taking GLP-1 products. A weight-loss diet carries the risk of a reduced intake of a range of vitamins and minerals. It is therefore especially important to pay attention to your intake of these nutrients, including vitamins D and K, while on a weight-loss diet.

Composition and dosage

Composition

Sunflower oil, gelatin capsule (gelatin, glycerin, purified water), vitamin K (menaquinone), vitamin D (cholecalciferol), vitamin K (phylloquinone).

Dosage

Take 1 capsule daily. As both vitamin D and vitamin K are fat-soluble, it is best to take the capsule with a meal containing fat to support their absorption. For maximum effectiveness, do not take it on an empty stomach.

There are several ways to incorporate Vitamin D3+K1+K2 Forte GymBeam into your daily supplement routine.

  • In the morning with breakfast. It fits naturally into your daily routine, so you can tick it off your list first thing in the morning.
  • With your main meal of the day (lunch). If your breakfast is mostly carbohydrate-based with almost no fat, it may make more sense to take this supplement with a meal containing more fat to support optimal absorption of both vitamins.
  • All year round, especially from autumn to spring. Vitamin D supplementation makes the most sense during periods with little sunshine. However, it should primarily be guided by your current blood vitamin D levels. Vitamins K1 and K2, on the other hand, can be supplemented over the long term if your regular diet does not provide an adequate intake.
  • If you take medication that affects blood clotting (anticoagulants, such as warfarin-based medicines), we strongly recommend consulting your doctor before taking this product. Vitamin K may reduce the effectiveness of these medicines.
  • If you have any further concerns about the appropriate dosage due to your health condition, pregnancy, breastfeeding or other medication you are taking, we recommend consulting a doctor or dietitian before using this food supplement. This product is not intended for children.

Warning

Food supplement. The recommended daily dose should not be exceeded. This product is not a substitute for a balanced and varied diet and a healthy lifestyle. Not for children, pregnant and breastfeeding women. Keep out of reach of young children. Keep in a dry place out of direct sunlight at room temperature.
