Main Highlights

CARDIOVASCULAR HEALTH - Our MenaQ7 Vitamin K2 MK7 supplements are heart healthy supplements that facilitate proper absorption of calcium in the arteries. Vitamin K2 has been shown to help the body utilize calcium in order to inhibit calcium deposits in the arteries for a protective, heart effect. If you think you have a calcium deficiency, it may not be calcium supplements you need. A Vitamin K2 supplement helps absorb calcium thats already in your body that you're already consuming.
STRONG BONES: When calcium is properly absorbed from the bloodstream, it can be utilized to build bone density. Taking bone health supplements like Vitamin K2 can help individuals who have thinning, weak bones to build stronger bones. Vitamin K2 is also believed to support healthy teeth, aid calcium absorption, support healthy brain function, promote healthy skin, and prevent wrinkles.
180 MCG MENAQ7 - MenaQ7 is a patented form of Vitamin K2 (MK-7) for bone and cardiovascular health. Our clinical dosage of MenaQ7 is stronger than the dosage in many Vitamin K2 supplements, and it is the only clinically proven dosage associated with improved bone and heart health.

Without magnesium, your Vitamin D supplement may not be fully utilized.
PREMIUM BIOAVAILABLE FORMS We use Vitamin K2 as MK-7 (the long-acting form with a 3-day half-life for sustained benefits), Magnesium as Glycinate (the gentlest, most absorbable form that won't upset your stomach or cause laxative effects), and cholecalciferol D3 in oil-based softgels for maximum fat-soluble absorption.
