MK-7 VITAMIN K-2 100mcg - 60 veg caps
What is MK-7 Vitamin K-2?
MK-7 Vitamin K-2 by Now Foods is a supplement based on Vitamin K, providing the active form K2.
What is Vitamin K?
Vitamin K is an essential vitamin, of the liposoluble type, whose main contributions to our health are:
- Regulates the blood coagulation function
- Contributes to cardiovascular health
- Bone health: participates in the process of bone protein synthesis, as well as improving bone density
- Improves immune function
Types of Vitamin K
There are 3 types of vitamin K:
- Vitamin K1: also known as phylloquinone, comes from green vegetables and legumes. The extraction of this vitamin from the vegetables by our organism is quite poor - it is estimated that only around 10% is used.
- Vitamin K2: also known as menaquinone, and is the type that has the highest absorption rate. Animal origin and fermented food are sources of vitamin K2. There are several K2 subtypes, such as MK-4 and MK-7.
- Vitamin K3: it is of artificial origin and is the one that is injected in newborns.
MK-7 Vitamin K-2 as the best form of Vitamin K
The vitamin K2 that is provided by MK-7 Vitamin K-2 is considered the best option when choosing a source of vitamin K. This is of the Menaquinone-7 type.
The difference in absorption of K2 versus K1 is due to the fact that vitamin K2 is a product resulting from a bacterium fermentation (K2 is found in fermented dairy products), besides the fact that, unlike other animals such as Ruminants, the conversion of K1 to K2 is not effective in humans.
The presence of K1 in the diet is usually 10 times more than K2.
The functions in the body of K1 and K2 are also different. The functionality of vitamin K is based on the modification of proteins to give them the ability to bind to the mineral calcium (activating the binding or chelation properties of calcium to proteins). Thus, on the one hand, vitamin K1 is mainly used by the liver to activate proteins that serve as a binding agent for calcium and intervene in blood clotting, and on the other hand, K2 (besides participating in the coagulation function) is preferably used by other tissues to deposit the calcium in the correct places, such as in bones and teeth, and prevent it from depositing in regions that it should not, such as soft tissues.
In terms of helping build healthy bones and other health benefits, vitamin K2 is believed to be the most powerful form
MK-7 Vitamin K-2 and Natto
MK-7 Vitamin K-2 makes use of the Natto source, one of the richest. Natto is a type of food derived from fermented soybeans in the traditional Japanese way.
Natto is made from the fermentation of soy, which is also an excellent supply of protein, fiber and isoflavones.
MK-7 Vitamin K-2 and Benefits
The main benefits of the vitamin K-2 (Menaquinone-7) from MK-7 Vitamin K-2 will be:
MK-7 Vitamin K-2 and Bone Health
Vitamin K2 will help deliver calcium to the body's systems that require it, and prevent, for example, the formation of kidney stones due to a bad redirection of calcium.
Thus K2 is necessary to help calcium and other minerals join the bone matrix and strengthen bones, preventing them from remaining in soft tissues and causing calcifications.
In fact, some studies support that vitamin K might be effective not only to stop bone loss in people with osteoporosis but also to reverse it (Study 1). This same research found up to an 80% reduction in fractures in patients with osteoporosis that had taken K2 supplements.
The risk is not to consume little calcium, but that there is a small amount of vitamin K
MK-7 Vitamin K-2 and Cardiovascular Health
By means of the correct supply and presence in our organism of the vitamin K2 we will avoid the calcification of arteries, producing a risk of heart attack. As mentioned in the previous point, the function of vitamin K will be to 'redirect' the calcium to the bones, without being delivered to other tissues.
Other supplements that are essential for this function will be Magnesium and Vitamin D3.
Who is MK-7 Vitamin K-2 recommended for?
MK-7 Vitamin K-2 is recommended for:
- People with family history of osteoporosis and/or risk of heart conditions.
- People who need to increase their calcium levels or as a prevention measure
- People who suffer from nutrient malabsorption as a result of some pathology, such as Crohn's disease.
