take 1 drop every second day

Posted by 5565967786853621888 on Jul 18, 2014

you can skip the recommanded usage and just take one drop (instead of 15) every second day. 80-drops bottle with 15 drops 3 times a day just runs out quickly. besides that- excellent product

It's a very good product. However, MK-7 is probably the best form. So, this product should contain both. Anyway, liquid provides a better absorption than softgel and i can get much higher doses quite easily. I wish iherb will continue to provide such a product choice !

pleasant, tasteless

As a means of obtaining K2 it is certainly painless. Since the benefits are largely long term, I can't say whether it is the best source or not. I can say that it doesn't have that funny buttery flavor that the K2/D3 liquid has, and which I rather like.

The best K2, period

Posted by 4943797960547833871 on Nov 03, 2015

Vitamin K2 works in conjunction with vitamin D, calcium and magnesium to build strong bones and teeth. It's also a crucial substance for making sure that calcium isn't deposited in your arteries (atherosclerosis) thereby helping to prevent heart disease and poor circulation. For men over 40 it's a great supplement to make sure that a certain part of the body keeps working the way you want it to, if you catch my drift… For menstruating women, it can help decrease excess bleeding. All in all, a key supplement for anyone wanting to improve their long term health. Update: I've now switched to Carlson Labs 5 mg capsules, which I find to be more effective and simpler to use.

Seems OK

Tastes OK. Might be causing problems with my sleep. I am taking it on faith; 10-12 drops per day.

Good product but too expensive
