I can't really tell how well it works, just that I have to take it to make other supplements work together.
I am happy with it.

After reading Jeff T. Bowles book, I upped my vitamin D3 intake. He made it clear to take a good vitamin K2 supplement to make sure calcium is properly utilized.He did not recommend any brand of k2 but said that he himself uses LEF Super K. I'm following his lead and getting good results.

I needed a K supplement to work with my Vit A and D3. This is it. I've purchased directly from LEF, but I can get the same high quality at a lower price here. Thank you.

We received this in error, but researched it and have been taking it ever since. We use Life Extention as an additional reference in regards to health products. They have good products and good research.

I have oly been taking this for a short while so I have no idea what it is doing for me. From what I understand about the ingredients I am assuming that they work well. I find them easy to swallow and the quality is as I would expect. Swanson shipping is fast so that they arrived quickly. As always, Swanson prices are the best anywhere.

Here's a product I can only relate its apparent results,. I notice that when I take Fish Oils and add E or Resveretrol, I get blotches of bleeding under the skin and occasionally when urinating coming from a Urethra issue. Since taking the K-2 I have noticed little of this happening. I believe this to be one of the best formulas and hope to get even better results in the fuiture.

In my recent research into bone health in later life, I found this to be very helpful in tandem with minerals and vitamins. I am hoping for excellent results from my recent bone scan!

After reading about how effective vitamin K may be I decided to try it. Swanson's Super K has been exceptional. I've had no problems taking it and I'm a very satisfied customer.

Rated 5 out of 5 by bethany high quality brand
I only take one a day compared to the same micrograms in 2 of Swanson's brand, so it's more convenient. One bottle lasts a month for my family of 3, which makes this a good value. I think many people are taking vitamin D now, but not K along with it. This is important to have a balance of nutrients. Most of us probably don't eat enough green veggies to get this vitamin K available in food.

Rated 5 out of 5 by indiecds A Must Have if You Take Heavy Doses of Vitamin D
The description says "Promotes healthy arterial health and healthy bones". Vitamin K2 has been shown to effectively keep calcium out of the places that you don't want it to be and in your bones where you do want it. This is especially important if you are taking high doses of Vitamin D. I take 10,000 IUs of vitamin D a day (temporarily until I get my levels up to 50 ng/ml) I am one of those people who gets calcium deposits where I don't want them if I take high doses of vitamin D cause vitamin D causes you to absorb more calcium from your intestines. To counteract that and prevent calcium deposits in soft tissues I take one of these with every 10,000 IUs of vitamin D3. My wife takes it to keep her arteries free of calcium.
