Question 2

How many mcg?

Accepted Answer

Looks like the K2-MK7 has been cut from 200 mcg to 100 mcg!

Question 3

How is the size of the pill? Is too big or small? I'm asking because I've difficult to swallow some pills in general.

Accepted Answer

I also agree with you Carl that it may be difficult to swallow certain pills.  I myself cannot swallow large pills, my gag reflexes will kick in.  Believe me, Life Extension Super K with Advanced K2 complex is a small soft gel pill that is easy to swallow.   The pill does not get stuck in my throat and neither do I gag as I am swallowing pill.The pill glides down my throat.  I'm am telling you Carl, this is one of my better purchases.  I hoped I answered your question.

Question 4

I've been reading about recommended daily dosages for Vitamin K and this product seems to exceed the recommended dosage by quite a bit. Is it safe?

Accepted Answer

Most researchers and doctors who have studied K2 now recommend 180mcg per day. It is safe if you are over a little bit as toxicity is low. They also recommend taking D2, calcium and magnesium at the same, time as all of these work together with K2. A very good book about K2 is called "Vitamin K2: The Missing Nutrient for Heart and Bone Health" and can be found here: http://www.amazon.com/Vitamin-K2-Missing-Nutrient-Health/dp/149697087X
