Although Vitamin K is best known for its role in normal blood clotting function, recent research has revealed Vitamin K's beneficial effects on bone and cardiovascular health. In bone tissue, Vitamin K is critical for the formation of healthy, strong bone matrix. In fact, bone quality is dependent on the presence of adequate Vitamin K. Vitamin K's role in arterial health revolves around its ability to support proper calcium metabolism in vascular structures. Vitamin K-2 is the most biologically active form of vitamin K. This product also includes the addition of Alfalfa which is typically known to be a source of natural Vitamin K. Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients.

Customer Ratings & Reviews

Vitamin K-2 is rated 4.7 out of 5 by 39.
Rated 5 out of 5 by from Research Indicates Synergy Between K2 and Vit D I have been taking D3 for many years now and in my continuing research about Vitamins and herbal supplements, I found many findings that indicate a synergistic relationship between D3 and K2. NOW is a trusted brand that I decided to add to my daily regimen about 6 months ago.

Rated 5 out of 5 by from MK-4 K2 I believe it's best to take both MK-4 and MK-7 K2. MK-7 lasts longer, but MK-4 activates all the proteins such as osteocalcin. One a day of this product with an MK-7 is a complete way to supply vitamin K2. Some people might object to the alfalfa, but I think it's OK as long as it's not GMO.

Rated 1 out of 5 by from This is the Useless MK-4 not the valuable MK-7 I thought that this was the same as the other Now vitamin K-2, with simply a higher number of pills..... so what a surprise when it arrived. They sneakily avoid putting MK-4 on the front label; instead they put vitamin K-2. All the info (Dr. Mercola and Oz) emphasise that the only valuable vitamin K is the Menaquinone-7 form (MK-7). That form of vitamin K is the only one that puts the calcium INTO your bones instead of ONTO your bones. .... on top of that, MK-4 is synthetically made.

Rated 5 out of 5 by from Don't forget the Vitamin K2 Swanson's is the best place to buy vitamins for your money. Doctors tell us to take vitamin D but vitamins K2 should also be taken with the Vitamin D. and Swanson's has the "can't be beat" prices.

Rated 5 out of 5 by from good price/quality My whole family takes this supplement, thus we go through quite a bit, quite rapidly. I like the higher quantity available in this bottle and love this brand as well.

Rated 4 out of 5 by from Seems ok but it has a lot of alfalfa Quality seems typical Swanson high, but it has a lot of alfalfa too, which I didn't realize when I ordered. You might prefer to avoid that.

Rated 5 out of 5 by from Take it all the time After my Naturopath told me to start taking K-2 I found this product and have never looked back.

Rated 1 out of 5 by from "Essentially Useless" After reading K2 and The Calcium Paradox I found out this dose doesn't provide any benefits. It is hovering at the maximum potency that is allowed to be shipped to Canada. That said this is no reflection on NOW Foods or Swanson adn I do like NOW Foods overall. I have since switched to NOW Foods MK 7 from Swanson of course.

Rated 5 out of 5 by from good brand I like this vitamin K-2. Cannot use the ones with natto because of allergy, but this one works great. Would recommend to anyone looking for K-2 supplement.

Rated 5 out of 5 by from Vitamin K with D I have heard docs speaking about synergism between D and K so I thought I would try it. Very good
Date published: 2013-12-08
Rated 5 out of 5 by from Vitamin K2 The first time I purchased K2 was the Swanson brand but they were out of stock and backordered. I wanted to keep taking it with no lapse of time, so I ordered the NOW brand. It is OK, but I like the description of Swanson brand better and will order it again next time even though it costs a little more.

Rated 5 out of 5 by from Good Complement to Vitamin D3 This product is a good complement to Vitamin D3 and is touted as a necessary ingredient for healthy bones. It's easy to take and I have had no adverse reactions to it.

Rated 5 out of 5 by from good for teeth and bones After learning that K2 is essential for proper distribution of calcium in our bodies, I decided to not only supplement my child, but to do the same for myself. I like the idea of growing old while maintaining healthy teeth and bones. My child gets K2 in liquid form; this product works great for me. I think this product is a good value and I trust the brand.

Rated 5 out of 5 by from Best price Great product and the best price I've found for this strength.

Rated 5 out of 5 by from Vitamin K2 helps vitamin d I take vitamin K2 to enable the vitamin D I take to have the desired effect. For me, the K2 helps with my flexibility and joint comfort. I will continut to take it just for this benefit.
Date published: 2013-07-26
Rated 5 out of 5 by from Good Quality, Good Price I am in the care of an MD who asked me to supplement with NOW brand K2 regularly, along with the regular Vitamin D3 supplement he prescribed. I emailed NOW to ask regarding whether the K2 they sell is derived from a GMO source, and they responded that it is GMO-free. The price from Swanson Vitamins is better than I can obtain it elsewhere.
