Hope for my bones
I ordered this Mega Vitamin K2 because I read the research of how high dose K2 affected Japanese women. I've been taking them regularly. I have no info at this point about DEXA or REMS results since I started them, but I am hoping these have a positive affect on my bones. They are very tiny, and easy to take.

Excellent product
Excellent product which my holistic practitioner recommends for me. Been taking it for years but I’m happy I found it on Amazon for a better price than where I was getting it.

High dose K2
One of the few high dose K2 supplements available. High-dose Vitamin K2 (primarily as menaquinone-4 or MK-4) has been studied extensively, especially at the pharmacological dose of 45 mg/day, which is approved in Japan for osteoporosis treatment. Quality manufacturer.

works but for a limited time
I am still working out how to fix my vitamin K problem. It appears that the mk7 form of K2 is better than the mk4 form. But the available dose sizes for mk7 are not big enough. As the literature notes, mk4 only lasts for about 4-5 hours and then I have to take more. For now, I am continuing to use this product but if I find an mk7 product with a bigger dose size, I may switch.
