Life Extension Super K with Advanced K2 complex

Ideal Forms of Vitamin K2
In recent years, two forms of vitamin K2 have been extensively researched and the findings reveal vastly improved effects compared to K1. The MK-4 form of vitamin K2 is the most rapidly absorbed and is now routinely used in Japan to maintain healthy bone density. MK-4, however, only remains active in the blood for a few hours. The MK-7 form of K2, on the other hand, remains bio-available to the human body over a sustained 24-hour period and to higher levels (7- to 8-fold) during prolonged intake. Both MK-4 and MK-7 have demonstrated remarkable health benefits when studied in human populations.

The Most Complete Vitamin K Formula
Vitamin K1 is the form found in plants and vegetables and should be part of most people’s daily supplement regimen. Even more important is inclusion of the MK-4 and MK-7 forms of vitamin K2. Based on data substantiating the long-acting effects of MK-7, it is now possible to ingest fewer total micrograms of vitamin K but achieve far higher sustained blood levels of this critical nutrient. The latest Super K formula provides vitamin K1 and the MK-4 and MK-7 forms of vitamin K2 in just one daily softgel. The virtue of this updated formula is that it provides the precise amount of the long-acting MK-7 form of vitamin K2 that recent human studies have shown provides optimal K2 levels over a 24-hour period. The MK-4 is included to provide the rapid increase in vitamin K blood levels that may account for its beneficial effects in certain studies.
