Vitamin K2

Posted by 5127777418962886626 on Nov 17, 2014

This is one of the few places I can get Vitamin K2 in this dose. I take 3 tablets 3 times a day for my osteoporosis. The product arrived in a couple of days with the free shipping.

Love this stuff!!!

Apart from those times when you haven't got enough greens into you and you feel deficient in K... this works really well if you've had a late night coffee (tea or even chocolate are also stimulants) and can't go to sleep. It seems to excrete the cafeine (or other stimulant) in the urine and you drift off to sleep naturally. This is the synthetic version of K2 (MK4) so I've switched to the MK7 (natural) version. Unfortunately the natural version is only 100 ug (50 times less) and not as potent as this one. Take this and you'll feel the difference a lot more easily. The first effect everyone seems to notice is stronger teeth and the fact that the plaque on the back of your teeth is no longer there. It's malformed calcium and is now being absorbed into your bones (which includes the teeth). If you want to convince yourself or someone else that K2 works try this version. :-)

CAUTION - Vit K antagonises blood thinners, CoQ10, magnesium, vit A, vit E - please be careful

Posted by Health-Is-Wealth on Mar 01, 2014

Please consider this one carefully. K2 made a hip issue worse and caused my knees to feel painful/swollen where there was no knee issue before. I believe there are cheaper/more effective/less harmful ways to prevent/reverse calcification and/or get rid of calcium spurs etc. If needed at all, I argue that vit K1 is sufficient - our bodies do a stellar job of converting it to vit K2, regardless of gut flora. And I suggest vit D/magnesium deficiency is more likely than vit K. I personally found my bone/endocrine health improved most significantly once I stopped drinking tap water (even filtered). I now only drink bottled spring water and use bottled or filtered water for cooking (and some washing, e.g. face/hair) - chloramine is not fit for human consumption. Even without doing/taking anything else - not drinking tap water made a significant enough difference that I wholeheartedly advocate it as a must-try for anyone suffering any kind of health issue. Note that vit K needs vit D, copper, B5 (and calcium) - if already low, vit K will lower them further (along with things it antagonises, e.g. magnesium).

Very good product

Posted by 4745946546308050361 on Aug 01, 2013

My doctor recommended me to take this vitamin together with vitamin D. I hope it can help me to fix vitamin D in my bones. It will take some time to the results appear. I, particularly and many other Brazilian people are buying so many vitamin D, at Iherb, because we all do a very specific treatment with high doses of Vitamin D. And he recommend the site. Thank you for the support.

a blessing

This is the only brand and strength of several I've tried that actually keeps me from being a "bleeder". I'm sticking with this.

not the cheapest for those who wants doses > 5mg

Posted by demonic-tree on Dec 11, 2012

i think it could be cheaper + no effect is achieved with the recommended dosage.
