Review: Best K2 - Superior Source is a great company if you haven't heard of them before. I've been using them for a few years as they offer excellent customer service, and the ingredients in their sublingual tablets enters directly into the blood. Bypassing the liver. The body can utilize the vitamin quicker and more efficiently. This is an excellent, high-quality MK-4 product. It's a good dosage, and I use it daily for bone density, cardiovascular health, and longevity, especially when I'm taking Vitamin D3. These instant dissolve tablets are gone in just a few seconds under the tongue (the best method) and are semi-sweet and good tasting.
Review: Happy Gal! - I am so glad I received my order from Superior Source for the K2-K4. I read articles a few days ago about the benefit of K4 that I was not informed about. I have taken my first 2 doses and going to stick with the product due to the benefits to my health and bones! It is a small tablet, and dissolves in my mouth quickly.
