Review: 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: Just received my second order of vitamin K. Ordered as it is supposed to clean out the arteries. Use with vitamin E, Niacin, lecithin and folic acid combo. ## Features - Vitamin Supplement Formula: Our Vitamin K2 MK-4 supplement is formulated with 500 mcg of vitamin K in each serving, supporting healthy soft tissue - Supports Bone Health: This health supplement supports the direction of calcium to bones, aiding in their strength and integrity - Instant Dissolve Tablets: This Vitamin K2 MK-4 supplement comes in a sublingual format, supporting quick absorption and easy intake - Senior & Bariatric-Friendly Formula: Our vitamin K2 supplement is ideal for people with sensitive needs because of the dissolvable formula - About Us: Superior Source has been formulating sublingual vitamins since 1998 in our family-owned manufacturing facility ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006607OIE | | ASIN | B006607OIE | | Age Range Description | Adult | | Allergen Information | Gluten Free | | Best Sellers Rank | #64,777 in Health ( See Top 100 in Health ) #24 in Vitamin K Supplements | | Brand | Superior Source | | Customer Reviews | 4.5 4.5 out of 5 stars (757) | | Customer reviews | 4.5 4.5 out of 5 stars (757) | | Date First Available | 24 September 2014 | | Format | Tablet | | Is Discontinued By Manufacturer | No | | Item model number | 90410 | | Manufacturer | Superior Source | | Product Dimensions | 3.66 x 3.66 x 6.05 cm; 22.68 g | | Units | 60.00 Count | ## Product Details - **Brand:** Superior Source - **Diet type:** Gluten Free - **Flavour:** Unflavored - **Item form:** Tablet - **Primary supplement type:** Vitamin K2 ## Images ![Superior Source Vitamin K2 500 mcg MK-4 - Bone Strength & Health Support Supplement - Vitamin K Supplement Helps in Soft Tissue Health & Calcium Absorption - 60 Sublingual Dissolving Tablets - Image 1](https://m.media-amazon.com/images/I/81+u3LvE+5L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Natural or synthetic MK-4?
