Buying Guide

Due to the different types and forms of vitamin K, it is confusing which one should consumer buy. Besides, there are other concerns about selecting a vitamin K supplement.

First of all, let’s know which forms and types of vitamin K supplements are more effective:

Forms of the supplement

Buyers have options to choose tablets or capsules of vitamin K. Range of the dosages is mostly from 50 mcg to 100 mcg. The drops of vitamin k are also available in the market which can be mixed with food or water.

Besides the liquid and pills, they come in chewable soft gel form which has a higher rate of absorption than other tablets.

Type of Vitamin K and which one should you go with

Vitamin K2 is the best among the three forms of vitamin K (vitamin K1, 2, and 3). From a clinical study, it has come to know that vitamin K2, with vitamin D, helps to prevent cardiovascular disease, preventing the calcification in coronary arteries of the human body.

Some natural foods are enriched with Vitamin K. If you properly take them, then no need to take any supplements of Vitamin K.

Vegetables, Soybeans Asparagus, Fennel, Leeks & Okra, Pickles (Cucumber, Sweet), Olive Oil, Dried Fruit, Chili Powder & Hot Spices, etc. are some examples of foods which contain Vitamin K.

MK-4 vs. MK-7

  • Menaquinone-7(MK-7) and Menaquinone-4 (MK-4) are the major forms of vitamin K.

MK-7 is must for our brain as well as MK-4. But Mk-7 isn’t present in the brain. Only Mk-4 helps to activate proteins structural cells of the brain. These are called VKDP (Vitamin K dependent protein). MK-4 controls the stress in the brain occur due to oxidation and also inflammation in the brain. There are about 15 VKDP identified by the scientists.

  • If you are going through pregnancy, you need to take MK-4, not MK-7 or another vitamin K as only MK-4 can go into the placenta.
  • There is MK-4 in human breast milk, not MK-7.
  • The long chain molecule of K2 like MK-8 or MK-14 is necessary for heart health.
  • MK-4 is made from animal and MK-7 is made from bacterial fermentation. If you prefer a non-synthetic form of vitamin K, I’m suggesting to take MK-7 because MK-4 is synthetically derived.
  • A positive side of MK-7 remain in therapeutic doses in the blood and stays longer than MK-4.
  • MK-7 is almost five times more active than MK-4.
  • Natto-derived MK-7 (100 mcg) in pills can be purchased if you are sure about the deficiency of vitamin K in your body. I mean doctor already has prescribed you to take. MK-4 is also found in the market in the form of pills but in higher doses (highest 5000mcq).
  • The equivalency of these two forms of the vitamin is under research. So it’s not possible to say anything about the doses of both MK-4 and MK-7 corresponding to each other.

Dose of Vitamin K Supplement

The ideal amounts of vitamin K2 are still not discovered yet. But it is most probably between 180 to 200 micrograms which are enough to make your body active.

Side effects The side effect is a familiar term with supplements. Most of them cause mild or fatal side effects due to their high dose of certain ingredients, which they used to increase its effect but instead, it led to a disaster.
