    30 Trillion Reasons To Buy D3 Complete

    Your body has 30 trillion cells. At the core of each cell is a Vitamin D receptor. These receptors act as switches, triggering vital functions such as immune strength, bone health, mood balance and more. Vitamin D is the only thing that can activate these switches. Without a steady supply of this essential nutrient, these functions will slow down, waver, and eventually cease to operate effectively. That’s why your body’s well-being hinges on Vitamin D.

    But Vitamin D alone isn’t enough…

    Vitamin D works best when it’s supported by the other 3 fat-soluble vitamins.

    Those are vitamins A, E, & K. When combined, these 4 vitamins complement one another to support an impressive range of health benefits.

    Younger Skin, Stronger Bones, And A Whole Lot More

    While many associate Vitamin A with eye health, its pivotal role in skin health is less known. It fuels the production of fresh new cells, supporting healthy and attractive skin. In fact, studies have shown that higher Vitamin A levels are linked to a youthful appearance.2 Plus, it teams up with Vitamin D to promote immune strength, bone health, and brain function.

    Protect Your Cells From Oxidative Damage

    Vitamin E is a robust antioxidant that protects cells from free radical harm, promoting overall well-being. It’s especially good for your skin, hair, nails, and heart. It also teams up with Vitamin D to strengthen your body’s natural defense against illness and infection. In D3 Complete, we include Vitamin E tocotrienol – found in the annatto plant of South America. This recently discovered form of Vitamin E has superior health benefits and a better safety profile than the more common form of Vitamin E used in most supplements today.

    Strong Bones And A Healthy Heart

    Vitamin K, existing as K1 and K2, supports health in a variety of ways. Among these, K2 (MK-4 and MK-7) plays a crucial role in promoting bone and heart health by directing calcium into your bones and away from your arteries. There's also growing evidence that Vitamin K might support better cognitive function as you age.3

    While some traditional Vitamin D supplements have one of these Vitamin K forms, only D3 Complete has all of them.
    Stronger Together
- A, D, E, & K

    When taken individually, vitamins A, D, E, & K support a wide range of essential functions within your body. And that’s good. But the real magic happens when you take them together. That’s because their collective impact is greater than the sum of their parts.
