Taking calcium supplements without K2 can improve bone strength, but it will also INCREASE THE RISK OF HEART DISEASE because only some of the calcium is deposited in the bones, where it is needed. Some of it is expelled via urine (which is why mainstream doctors recommend such high daily amounts of it) but the rest--dangerously--is packed around organs, where it does not belong and where it will do you harm. If deposited around the heart, it will increase your risk of heart disease; if deposited around the kidneys, it will increase the risk of kidney stones; if around the gallbladder, the risk of gallstones, etc. So you need to (1) take K2, which will deposit the calcium in your bones, where it belongs; (2) make sure you get enough D3 (from the sun whenever possible, then from supplements at other times), because it works synergistically and it will help your body absorb the calcium you ingest, whether from the diet or from a pill; and (3) reduce any calcium supplements you take, because once you have enough K2 and D3 your body will be able to use any calcium you ingest (instead of peeing it out and/or packing it around vital organs). You should also make sure you get enough magnesium if taking calcium, just don't take the two together because one blocks the absorption of the other. Happy bone health!

Vitamin K2 has been found to be very protective for heart health and bones. Vitamin K1 is found in green veggies and not easily absorbed. Some think it is less important than K2 (MK-4 and MK-7) while others feel it is the best form of K1 so taking both in one supplement seems like a win-win to me.

This LEF product of vitamin K has a great consentrations espesially K2. It is important vitamin when you use high doses of vitamin D3. K2 moves calsium from veins to bones where it is needed and your veins stays cleaner. :) I take one capsule only three times a week so this bottle is quite affordable. I highly recommend!

I like it but would like to see more vit K2 MK7 considering how expensive it is. and I mostly buy it to get the MK7 part.

Nice combination of K. Is the appropriate dose to take with D3, 10,000u if you read the literature.

My first experience with vitamin K supplementation was Jarrow's K2 MK-7, and that actually seemed to have a better effect, at least on my teeth. My teeth felt glossy and hard, whereas with this one, I notice no discernible difference from normal. Others have reported the opposite experience, which is why I decided to try this too - but it does not work so well for me, so I will go back to K2 MK-7. Might be worthwhile for you to try both to see which one you prefer. Take it with vitamin D to reduce (the risk of) atherosclerosis and put calcium in the bones where it belongs.

take 100mcg of k2 mk-7 pr. 1000iu of D3 and 1000ui of A. this is the latest scientific verified protocol. you will see great results on this. the k2 is the most pricey of the protocol if you do 6000iu d3 and A a day as it means popping 3 caps a day. but this is how you tap into the power of d3 safely. my teeth a smooth and my dentist cant believe how strong they are. also hormones balance themselves. I never get sick.

The only product I've found which combines K1, K2-4 and K2-7 at that price level. Highly recommended.

My cardiologist recommended Super K with Advanced K2. The order from IHerb was processed quickly.
