It works

Posted by Reviewer3255962 on Nov 12, 2010

I had a very enlarged blood vessel in my neck (left side), which actually hurt to touch. Within weeks of taking Life Extension Low Dose K2, I noticed it had reduced in size. I have now been taking it for over 1 1/4 years (1 twice a day). The diameter of that blood vessel has halved and it does not hurt to touch any more. It makes me wonder how much bone tissue had been lining my blood vessels. I would say it has contributed to preventing my early demise..I am 53 going on 54yrs.

Life Extension, Vitamin K-2, 45 mcg, 90 Softgels

Posted by noneofyourfrigginbusiness on Jul 08, 2010

High quality, low dose; vitamin K-2 from dietary sources may reduce the build up of calcium in arteries that leads to hardening of the blood vessels, says a new study. Animal studies with vitamin K2 as Menaquinone-7 show a dramatic prevention of typical bone loss biochemistry that is associated with the aging process.

Good Product

Posted by adechamplain on Apr 14, 2013

This product seems of the highest quality however I have now purchased the Super K with K2 formulation from Life Extension. Life Extension and Thorne Research are companies I trust and are always high quality products without any fillers and expedients like Magnesium stereate which are toxic to the liver. I just think from my research that if you supplement with Vitamin D which I do (and I think most people should) then you need a higher dose of Vitamin K2 than this product supplies which is why I've moved to the Super K supplement and will not give this product a 5 star rating. Vitamin K2 is required along with Vitamin D, Calcium and other minerals to help your bones stay strong as you age. Of course some weight bearing exercise (running, weight training etc) is also a great help but K2 helps the calcium to go where it's needed in the bones rather then be directed in the soft tissue and do damage to the body. I highly recommend everyone read about the benefit of K2 and start using this supplement in your daily regime but I'd suggest a higher dose than this.

Dr Oz swears by this, don't bother with any other K variant, this is the gold standard. iherb continues to provide the best in product quality, competitive price & excellent delivery service, thanks!

It is nowhere mentioned that the MK-7 is derived from fermented, organic natto

The source of the MK-7 is not mentioned on this product. I am almost done with the first pack and have my doubts about the efficacy of this product, will be looking to shift brands.

Low Dose K2

Posted by 4949931180143015639 on Oct 30, 2012

Fantastic service from iherb. I take the low dose Vitamin K2 in the hope it will remove some of the calcium from my arteries and love the tiny capsules.

Life Extension, Vitamin K2, Low Dose, 45 mcg 90 softgels

Posted by Reviewer3327198 on Jul 20, 2009

It's easy to take and well packaged. The benefit will be long term, so I can't really comment on a health result at this stage. It's seems to be very good value.

pounding headache

Posted by Reviewer2106073 on Dec 16, 2014

I think I don't require a vitamin K supplement because it gave me an immense headache that last 2 days. After repeatly trying the jury is out. Not meant for me.

Bought it for my mum, as it's low dose so it's safe for her. I must say great quality and very good price. Will definitely buy more.
