  • This K2 supplement was derived from natto, a fermented-soybean product

  • Features the biologically active form of vitamin K-2

  • Encourages optimal calcium uptake throughout the body*

Swanson Ultra Natural Vitamin K2 (Menaquinone-7 from Natto) is the most biologically active form of vitamin K2. Everyone knows about calcium and vitamin D for bone health, but what about vitamin K2? If there’s one vitamin you should know more about, this one’s it. While vitamin K1 is mostly involved in blood clotting, K2 helps to activate the proteins that regulate where calcium ends up in the body. Meaning this little-known vitamin is a powerhouse when it comes to healthy bones, and a healthy heart.* Our vitamin K2 is derived from 100% natural Japanese natto (a fermented soybean product), and because the Western diet is typically low in fermented foods, it also tends to be low in K2. So stock up on this biologically active form of vitamin K2 today for maximum benefits!

Rated 3 out of 5 by from Corn in it I am shocked that there is corn in it.

Rated 4 out of 5 by from Quality Vitamin K supplement I don't feel the difference between this product and lower-priced versions of the vitamin K but I trust Swanson's better quality rating on the product to be worth paying a Little extra.

Rated 5 out of 5 by from I take it with calcium to maximize the absorption. It is very expensive, to me, even on here but I try to stock up on the BOGO so as not to run out!

Rated 5 out of 5 by from Important Vitamin VItamin K2 is vital to our health. Do the research concerning what it does in the body. I have several health concerns that I'm hoping this vitamin will address.

Rated 5 out of 5 by from Great product Love this sugar. It doesn't have an after taste, as some fake sugar does. Also a good sugar substitute in receipe.

Rated 5 out of 5 by from Dietician Recommended This is another supplement recommended by my dietician. It is affordable and easy to take. I have to take 3 to add up to what she suggested, so would be happy if there was a larger quantity in the bottle or a higher dose so I would only have to take one. Other than that, its a good product for a good price.

Rated 5 out of 5 by from Great K2 I love this K2 - I take it to help the bones. The pills are very small, dark brown and easy to swallow. This form of vitamin K (menaquinone) is believed to result in much more stable serum levels and accumulation than other forms. This product also comes from natto, which is fermented soybeans - some MK-7 is synthetic and it may not be as effective. It's another great Swanson product at a great price. Highly recommended.

Rated 5 out of 5 by from Super food - Natto. The super food- natto. I eat natto but I ran out natto sometimes. This supplement is easy to store in my shelf and easy to take.

Rated 5 out of 5 by from Excellent Product. As many know that whenever one takes Vitamin b12 always add Vitamin k2; these two should always be together for them to work properly.

Rated 3 out of 5 by from Sticky Capsules I'm on my 3rd bottle of this and of the three bottles, two have held capsules so sticky that it is hard to even shake them out of the bottle. But they are small and easy to swallow. And it's really hard to know if this is working or not so I will leave not a perfect rating but not a poor one either. I trust Swanson and the research that i've done tells me that this is the right thing to do when taking calcium--it's just difficult to measure how well it is working for me.

Rated 5 out of 5 by from Need to take if you take but D3 Don't know if it's working, only know I read you need it if you take bit D3

Rated 5 out of 5 by from Good stuff I've been using this product to compensate not eating enough greens which give you vitamin k.

Rated 5 out of 5 by from Deal Good stuff. Just to remember to take it with your 8000 D3 a day

Rated 4 out of 5 by from K2 helps D-3 be absorbed by the body I take K-2 with my cholecalciferol when I can afford to.
Date published: 2013-10-30
Rated 5 out of 5 by from Great product! This same product (ingredient-wise) cost so much more in stores - and is hard to find. And the Vitacost brand is in an Evening Primrose base. Only tip: take on an empty stomach for better absorption. I take it first thing in the morning, and it has never bothered my (delicate) stomach.

Rated 5 out of 5 by from Gives Peace of Mind I had been reading that if you take Calcium and Vitamin D then you should add K2.

Rated 5 out of 5 by from Feeling Better I have only begun taking this product, I feel good about it though because of the Quality of all Swanson products. I am feeling better than ever about my supplement purchases, now that I have found Swanson, I recommend your products to my friends and family.

Rated 5 out of 5 by from Excellent Vitamin K is so important for health. This is a great value for a great product. My husband said he could really tell a difference after adding this product to his daily regimen.
