Is Vitamin K for You?

There are certain factors that can be present that would indicate that adding a vitamin K supplement to your diet would be beneficial. If you have a family history of heart disease or osteoporosis, adding vitamin K to your daily routine can have extremely positive effects.

The vitamin K prevents the blood vessels from calcifying. Another reason vitamin K may be for you is if you don’t eat a lot of vegetables. Today’s society is full of fast food restaurants and processed foods making vegetables a thing of the past. For this reason, vitamin K can go a long way toward making up for this lack.

Vitamin K is NOT for You If…

Vitamin K2 supplements should not be taken unless recommended and monitored by your doctor is you are pregnant or nursing. Another reason not to take vitamin K is if you have suffered cardiac arrest or stroke in the past or you are prone to blood clots. Your doctor should be consulted before adding this vitamin to your diet in all circumstances. It is much safer to get the okay from them than to take a chance.

Types of Vitamin K

There are three types of vitamin K available: K1, K2, and K3. We have provided you with a little bit of information below on the different kinds and what they do for you.

  • Vitamin K1 – Another name for vitamin K1 is phylloquinone is found in plants, especially green vegetables. When ingested, vitamin K1 goes right to your liver and helps to maintain normal and healthy blood clotting.
  • Vitamin K2 – This form of K2 is also called menaquinone. The bacteria that line your gastrointestinal tract make up this form of vitamin K. K2 is used by the blood vessel walls, tissues and bones except for your liver.
  • Vitamin K3 – Also known as menadione, this synthetic form of vitamin K is not really recommended. There have been reports of toxicity that has occurred in babies that have been given synthetic K3 through injection and it can cause problems for adults as well.

Vitamin K2 is the best form of vitamin K to take and is readily available in supplement form. This form of K is all natural and even at 500 times the recommended daily amount it does not become toxic. Vitamin K2 is produced by fermented foods and is made in your body as well. Of course getting the right amounts of vitamin K2 through the foods you eat is the optimal way but this rarely happens. This is why a good quality supplement is so important. It can help you get what you need in a simple way.

Taking the Right Dosage

Dosage amounts of vitamin K2 can vary per person and you should get that dosage information from your doctor. It usually ranges between 45 micrograms and 185 micrograms each day for adults. If you are on anticoagulants you need to be very careful taking the higher range of that dosage.

Most people that are not taking anticoagulants and that are healthy in general usually take about 150 micrograms a day but this should be determined for you by a healthcare professional if there is any question as to the right amount for your specific health needs.
