BOOSTS IMMUNE HEALTH - If you're looking to support your immune system, copper is an excellent way to do so. That's because you need to have the appropriate amount of copper in your system for your body to be able to create a healthy white blood cell count. Copper is also an essential component of vital antioxidant enzymes that help replenish and protect your body, especially when stress, damage-causing free radicals and sleep concerns start to add up.

EXCELLENT FOR JOINT FUNCTION - For thousands of years, wearing a copper bracelet was thought to be a remedy for joint health concerns. When taken internally, a chelated copper supplement can support health from within your body due to the role it plays in promoting connective tissue health and healthy muscles.

SUPPORTS RED BLOOD CELL FORMATION - When combined, iron and copper work to create hemoglobin and red blood cells within the body. Not only that, but copper promotes the body's role in absorbing iron from the intestines and into your liver. This is significant because iron is vital in the creation of red blood cells, which are responsible for delivering oxygen to tissues throughout the body.

BENEFITS OF ANTIOXIDANTS - In daily life, the human body faces a familiar nemesis - free radicals. Free radicals can enter the system in a number of ways, including via the air we breathe and the foods we eat. Free radicals are even a natural byproduct of energy production in the body. So, it's important to make sure we're ingesting the proper amount of antioxidant-rich foods and antioxidant supplements. Antioxidants neutralize free radicals and can help protect our body from oxidative damage.

BENEFITS OF MINERALS - Minerals are inorganic compounds that are essential for helping your body grow, develop and maintain health. The human body is incapable of performing most functions without minerals as they assist the body in a wide range of metabolic and chemical functions within the system. This formula provides you with calcium (bone health, cardiovascular function) magnesium (nerve and muscle health), selenium (cellular health), zinc (immune health) and more.

B-COMPLEX BENEFITS - The B vitamins in this multi deliver many health benefits, including energy, metabolism and concentration (vitamin B1), energy (vitamin B2), mood regulation (vitamin B3), brain health (vitamin B6) blood and cellular health (vitamin B9) and general brain support (vitamin B12).
