Vitamin K is an essential fat-soluble nutrient that plays a pivotal role in bone health, heart function, brain support, and overall longevity. Often referred to as "Activator X" by Dr. Weston Price, Vitamin K2 is especially important for directing calcium out of soft tissues, like arteries, and into bones and teeth, where it belongs. Without sufficient Vitamin K2, calcium can accumulate in the wrong places, contributing to arterial calcification, joint stiffness, and poor bone density.
Vitamin K2 in the MK-7 form is largely absent from modern diets due to the decline in traditional animal foods, particularly aged cheeses and organ meats. Purely K delivers a clinically effective dose of Vitamin K in three essential forms, ensuring full-body support for calcium metabolism, vascular health, and cellular energy production.
A UNIQUE THREE-FORM FORMULA
Most Vitamin K supplements focus only on K2 or provide a single form, leaving gaps in effectiveness. Purely K is a synergistic blend of three bioavailable forms:
✅ Vitamin K1 (Phytomenadione)
✅ Vitamin K2 MK-4 (Menaquinone-4)
✅ Vitamin K2 MK-7 (Menaquinone-7)
Each form serves a unique function in the body, making Purely K a complete vitamin K solution that maximizes its benefits.
K1: ESSENTIAL FOR BLOOD CLOTTING & ENERGY SUPPORT
Vitamin K1, or phytomenadione, is primarily found in leafy greens and plays a critical role in blood clotting. It activates proteins in the blood that allow for proper coagulation, helping to prevent excessive bleeding. In plants, it functions similarly to CoQ10 in humans, supporting cellular energy production.
One capsule of Purely K contains 1000 mcg of Vitamin K1, far exceeding the minimal Recommended Daily Allowance (RDA) of 120 mcg for men and 90 mcg for women. While K1 is recycled by the body, certain conditions like intestinal malabsorption or liver dysfunction can inhibit this process, making supplementation beneficial. Symptoms of deficiency may include easy bruising, prolonged bleeding, and heavy menstrual cycles.
For those taking systemic enzymes, aspirin, or other blood-thinning medications, K1 is crucial for maintaining proper balance. Purely K provides a high-quality source of K1 from evening primrose to support healthy coagulation while ensuring optimal nutrient absorption.
K2 MK-4: THE BONE & BRAIN SUPPORTER
Vitamin K2 MK-4 is found in grass-fed animal products such as butter, egg yolks, and liver. It is the primary form used by the body for bone mineralization, brain function, and hormone balance.
Each serving of Purely K contains 2000 mcg of MK-4, delivering a substantial dose for supporting bone density, cardiovascular health, and neurological protection. Therapeutic studies have used doses up to 4500 mcg, which can be easily achieved by consuming two capsules daily alongside a nutrient-rich diet.
Research suggests that MK-4 may help reduce the risk of prostate cancer, protect brain function, and act as a CoQ10-like molecule by enhancing mitochondrial energy production. This makes it essential for cognitive health, athletic performance, and overall vitality.
K2 MK-7: LONG-LASTING CALCIUM REGULATION
Vitamin K2 MK-7 is the most bioavailable and longest-lasting form of Vitamin K2, ensuring sustained benefits throughout the body. Found in fermented foods like natto and aged cheeses, MK-7 is highly effective at activating osteocalcin and matrix GLA proteins, which regulate calcium deposition in bones and arteries.
Deficiency in MK-7 is widespread, particularly in Western diets. Without adequate intake, calcium can accumulate in arteries, increasing the risk of cardiovascular disease, osteoporosis, and joint issues. Studies show that MK-7 supplementation can reverse arterial blockages, increase bone density, and reduce the risk of osteoporosis.
Beyond calcium metabolism, MK-7 has been shown to reduce insulin production, lower the risk of Alzheimer’s disease, prevent varicose veins, and even enhance cellular energy production. Unlike K1 and MK-4, which have shorter half-lives, MK-7 remains in circulation longer, making daily supplementation the best way to maintain consistent levels.
