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!

Best K2 I have used. Helps keep my D3 levels up and my labwork looks amazing. Will continue to buy and have used this for over 2 years.

Dr. Thomas Levy has written a book, "Killer Calcium". This refers to the implication of calcium deposits in many conditions which lead to premature death. It has been known for decades that calcium deposits, AKA hardenting of the arteries, are responsible for closing the arteries. The arteries close naturally with age, reaching about 35% of their youthful diameter at age 90. It is at this diameter that the inner ear malfunctions and people begin to fall. However the arteries can close at any age if the diet does not ionize the calcium atoms. LEF Super K2 is helpful in managing calcium in the body. I use LEF Super K2 as part of a supplementation program to maintain healthy arteries of maximum diameter, along with a daily dose of iHerb nicotinic acid to exercise the capillaries to their maximum diameter.

Vitamin K2 helps the body to move calcium from the blood stream and into bones and teeth. Kale is a great natural source for Vitamin K but I dont get to eat that every day. I love the fact that this one contains the most essential types of Vitamin K2 out there in one little softgel (Mk7 AND Mk4). Its also a bonus that the vitamins themselves are contained in extra virgin olive oil, nice touch. This item is permanent on my shopping list.

Apparently discontinued doesn't mean no longer made (as per my dictionary). By discontinued iHerb means they decided to no longer stock it nor do they stock any comparable product. It is still listed on the manufacturers site as available for order so WHY HAVE YOU STOPPED STOCKING IT???

This formulation is the only one that I recommend to people needing serious Menaquinone supplementation; especially where there is a concern over hypercalcemia or calcium deposits. There is also a simple, low dose K by the same company that I use occasionally as maintenance or as a complement to a low-dose Vitamin D supplementation, or even in treating calcium issues in small dogs but, overall, the Super K is The One out of all the K formulations on the market. You can spend the hours and hours required to research Vitamin K in all it's forms and functions, and then more hours perusing all the formulations on the market (many of which, by the way, are perfectly adequate), or you can take my word for it that Life Extension's Super K is the best bet.

Love the amount of K2, and also love that you get a blend of other K vitamins more a more powerful synergistic effect. Also, no bad additives or fillers. This is a winner.

This is a 90 day supply with a good sized dose of various forms of vitamin K. I'm taking one capsule daily with 2000IU of vitamin D, Life Extension's 5000IU Vitamin D with Vitamin K and Iodine looks like a great alternative if you're looking for a well priced, good quality product. Nothing nasty hidden in the list of ingredients.

As I have osteo arthritis I presume I also have Osteopororsis as the two are the same problem according to Dr Wallach and Dr Peat. SO following their nutritional advice I am now not only PAIN FREE but looking forward to removing the little bony lumps that had started on my fingers in 4-9months. Vit K will help and I haven't noticed any side effects at all. Finished half a bottle.

Hard to say it it works. But i guess its like with oil in a car. You gotta have it even though you don't notice.

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.
