About this item
Product details
What most people know about vitamin K is that vitamin K must be present for our blood to be able to clot. But vitamin K has many other benefits in addition to enabling our blood to clot.* Since 1984, Thorne has set the standard for the exceptional formulation and quality manufacturing of nutritional supplements. Thorne delivers premium, science-based products, a health diagnostics technology platform, and the latest in medical education. With more than 350 products, Thorne is the most dispensed brand by 30-to 40-year-old health-care practitioners. Thorne is dedicated to improving the health of our community as well as increasing the knowledge of nutritional health and wellness. Since 2012, Thorne has partnered with educational institutes and local charities to donate more than 1M in products and profits. Thorne products do not contain any unnecessary binders, coatings, disintegrants, fillers, or lubricants (including magnesium stearate) that could impair absorption. Thorne adheres to the FDA’s current Good Manufacturing Practices (cGMPs) and has the highest number of NSF Certified for Sport products which test for more than 200 banned substances for elite athletic competitions.
