GETTING ENOUGH K2 – Vitamin K2 comes from meat, eggs and cheeses. Some people avoid these foods for health reasons, which can make it hard to get enough. This supplement contains the form of vitamin K2 called MK-7, which has been clinically studied for arterial health.

STAYS IN YOUR SYSTEM - Vitamin K2 remains biologically active in the body far longer than vitamin K1: measurable levels of K2 (MK-7) have been detected 72 hours after you ingest it. That gives your body more time to make use of all that heart-healthy vitamin K

SECRET WEAPON FOR LONGEVITY? Selenium is among several minerals found to be prevalent in some of the world’s longest-living people. Super Selenium Complex contains three forms of selenium, along with vitamin E, for optimized health and longevity support.

ADDRESS THIS AGING FACTOR - Each type of selenium in our formula helps your body fight against oxidative stress, a key factor that contributes to the aging process. How, you ask? Your body utilizes selenium to make a group of powerful antioxidant enzymes (glutathione peroxidases).

THYROID, HEART & BRAIN SUPPORT - Selenium's ability to promote a healthy inflammatory response and quench free radicals has led scientists to explore its impact on other factors related to oxidative stress, particularly supporting heart and brain health. Selenium may also support healthy thyroid and immune function.
