Vitamin K

Vitamins K1 or K2?

K vitamins are part of the fat-soluble vitamins, just like vitamins D, E and A.

K vitamins exist in different forms including phyloquinone (vitamin K₁), that we find mainly in green vegetables (spinach, salad, cabbage ...) and the group of menaquinones (vitamin K₂).

The length of the side chains of vitamins K2 determines their name:

- Menaquinone 4 to 13 or MK-4 to MK-13

Quality dietary supplements usually use vitamin K2 MK-7. It is rarely found in our diet since it is naturally and in large quantities in the Natto (fermented soy seeds), a traditional dish consumed mainly in Japan, but whose intense smell and the little familiar taste reduce its attraction.

Benefits of Vitamin K: Frame and Coagulation

Frame

Like vitamin D, vitamin K promotes maintaining a normal frame. This is why these 2 vitamins are frequently associated in food supplements. For example:

• Vitamin D3K2 at 800 IU (or 20 μg) vitamin D3 and 20 μg of vitamin K2 (MK-7) per drop. Ideal for children.
• Vitamin D3K2 strong at 2000 IU (50 μg) vitamin D3 and 50 μg vitamin K2 (MK-7) per drop. Ideal for adults.
• For adults who want to optimize their framework: Vitamin K2D3 With 2 times more vitamin K2 than vitamin D3. In a drop, 1000 IU (25 μg) vitamin D and 50 μg of vitamin K2.
• Synergy with vitamins D, E and A: Vitamin deka, synergy of 4 fat-soluble vitamins in one drop.

Coagulation

In addition to supporting the frame, vitamin K participates in normal blood coagulation.

For whom is vitamin K advised?

• For seniors
• For growing children
• Among those who are supplemented in vitamin D and who wish to optimize his action

The advantages of vitamin K2 MK-7

High bioavailability

Vitamin K2 MK-7 has high bioavailability. Thus, it is efficiently absorbed by the body.

Long duration of action in the body

Vitamin K2 MK-7 has a half-life of 3 days (72 hours). In other words, half of the vitamin K2 is still present in the blood after 3 days.

In comparison, vitamin K1 has a short life in the body, about 2 hours.

Vitamin K2 MK-7 remains active in your body 36x longer.

Production of vitamin K2

There are two approaches for the production of vitamin K2 MK-7.

The vitamin K2 Mk-7 organic synthesis has advantages compared to vitamin K2 from fermentation:

1. The production of vitamin K2 by fermentation presents 2 disadvantages:
   - The fermentation generates different forms of K2 vitamins, MK-7 mixed with MK-4 to MK-6.
   - A biologically less active or inactive form of MK-7 (CIS form) is also formed in more or less large proportions depending on the fermentation process.
2. Vitamin K2 MK-7 from an organic synthesis comes from geraniol and farnesol. These are purely vegetable substances:
   - The geraniol is, for example, in the essential oils of geranium, rose and coriander.
   - The farnesol is a component of rose essential oil as well as anise and jasmine.

The advantage of this organic synthesis is that it makes it possible to obtain only the biologically active form of the MK-7 (trans form).

Privilege the vitamin K2 "Trans" active

A compared test 33 products DR Jacob's® Vitamin K2 source biologically active (trans) and 109 products containing vitamin K2 of a competitor.

91% of DR Jacob's® products containing the Vitamin K2 Trans Active reached the reported quantity, but only 50% of competing products.

A test of 52 products revealed that even though half of the products contained sufficient amounts of vitamin K2, 50 of them contained less than 50% of biologically active trans. Vitamin K2. This means that they contained less than 50% active ingredient.

Vitamin K2 of Dr. Jacob's®

Dr. Jacob's® uses vitamin K2 in all-trans mk7 form in all its products containing vitamin K2. Only the biologically active trans form is formed.

Find the all-trans vitamin K2 in combination with vitamin D, with identical concentrations of these 2 vitamins:

• For children: Vitamin D3K2 at 800 IU (or 20 μg) vitamin D3 and 20 μg of vitamin K2 (MK-7) per drop.
• For adults: Vitamin D3K2 strong at 2000 IU (50 μg) vitamin D3 and 50 μg vitamin K2 (MK-7) per drop.

For adults or seniors who want to optimize their frame, opt for all-trans vitamin K2 in combination with vitamin D, but with 2 times more vitamin k than vitamin D:

- Vitamin K2D3. In a drop, 1000 IU (25 μg) vitamin D and 50 μg of vitamin K2.

Synergy with vitamins D, E and A:

- Vitamin deka, synergy of 4 fat-soluble vitamins in one drop.

Dr. Jacob's® also offers a Vitamin k2 Mono-ingredient, All-Trans solubilized in TCM coconut oil to optimize its assimilation.
