It supports healthy blood vessel dilation, a process called vasodilation. This promotes healthy blood flow, allowing the heart to pump efficiently. Magnesium Supports Overall Heart Health – Magnesium supports a variety of functions within the body, including bone health, but it is especially beneficial for heart health – specifically healthy blood vessel function. Magnesium relaxes the smooth muscle in blood vessels, a key component in blood pressure support. It even promotes healthy heart rhythm and artery health. This formula includes two types of magnesium, magnesium oxide and magnesium citrate, which offer both fast-acting and slow-release benefits. Special Dual-Action Mineral Formula – Magnesium and potassium are known as "sister minerals" because they participate in many of the same biological reactions. While they are beneficial when taken separately as a mineral supplement, it's more convenient to take them together.
