stronger bones to combat osteoporosis

Posted by Reviewer3047163 on Aug 19, 2010

after doing a lot of research on building stronger bones, I've decided to take this formula along with my calcium, magnesium,zinc, strontium, and vitamin D3.

strange allergic reaction

Posted by Reviewer2818474 on Nov 28, 2011

When I take this, within 1/2 hour the skin on my face, elbows, knuckles, wrists gets really red, hot, and itchy! I've never had a reaction like this to ANYTHING before. Just bizzare. I wish I could take this, such a promising supplement. Although I'm in the minority, looks like I'm not the only one having a problem.

Healthy bones, teeth and arteries!!

Posted by sweetheart on Jul 23, 2012

A very good product: K2 in two different forms! K2 has many benefits but it's not easy get it enough from food. Helps maintain healthy teeth as well!

A Good Combo

Posted by Reviewer2961002 on Aug 10, 2010

Since research seems to suggest different benefits for different types of "K," this is a good "hedge your bets" combo. Because some of the amounts seem on the high side, and because K is (I believe) fat soluble, I am currently only taking this every other day. I decided to start it when I started taking Vitamin D to raise my lowish D levels, as research suggests K2 may be able to keep any increases in calcium out of the arteries and in bone instead.

artery and bone protection

Posted by Reviewer1268836 on Sep 14, 2010

I haven't had tests to confirm the value of this, but it along with vitamin D are supposed to prevent calcium build-up in arteries and instead direct it to your bones.

Best choice of vita K...

Posted by Reviewer2963961 on Sep 23, 2010

Life extension has the best supplements and you can tell. This combination of vita K works better than K2 alone for bone strength and osteoporosis. It also allows the calcium to go where it is needed, (bones) not in the arteries. Plenty of new information about vita K2 and everything it has been shown to do. Read up! Add plenty of vita D3 and a little extra calcium.
