Natto derived
By Suz
Heads up for anyone who is soy or estrogen sensitive.
I purchased this brand as it stated "contains No soybeans" and I am estrogen sensitive. After taking it for a little over a week I noticed continually worsening soreness and pain in my breasts. I contacted the manufacturer and was advised that one of the K2 ingredients did come from Natto (which comes from fermented soybeans) and would be a phytoestrogen.
I am sure the product is great for anyone that is not estrogen sensitive. I did like the small size of the capsule. They were also very nice on the phone for advice. I did not buy this direct from their company and so cannot return it for a refund.

Saving your bones
By Marilyn D. Kagan
Have you started on the road to osteoporosis? Do you have trouble with taking calcium? This is a product that has no calcium, but if one takes it for a year, and has a Dexa scan to compare, will strengthen your bones without the dangers that calcium has for you personally. A cousin of mine took this for a year and her Dexa shows that her bones have strengthened. I have calcium absorption problems, so I ran to the computer and ordered these capsules. It's only a few weeks, so I'll have to order a few more jars, and see what happens after a year, but from what I've read, it should help a lot. The capsules are small, and taste sweet. That alone is an advantage!

Finally a "pure" Vitamin K supplement
By S. Smith
Finally a vitamin supplement with NO additives, fillers, magnesium stearate, soy lecithin or other chemical by products. "LifeExtension" and "Pure Encapsulations" are the top two manufacturers on my list for "pure," high quality vitamin supplements.
