Does what other Vitamin D supplements can’t

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. 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.

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, E, K, & D 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.

Frequently Asked Questions

  • I already take a multivitamin that includes A, E, & K. Will I be getting too much of these vitamins if I take D3 Complete?

    No, there’s no need for concern. D3 Complete is meticulously formulated to deliver optimal amounts of each nutrient. Additionally, the vitamins within D3 Complete are synergistically balanced to complement and bolster one another, promising maximum health advantages. It's crafted to be both secure and effective for daily intake. While most multivitamins offer only modest amounts of each component. However, if you have concerns about your vitamin intake or its compatibility with your health conditions, you should consult with your healthcare provider.

  • How much Vitamin D should I take daily?

    It depends. A variety of factors such as age, weight, skin color, and even geographical location affect the amount of Vitamin D a person needs. At the lower level, recommendations from The National Institutes Of Health and the Endocrine Society range from 400-2000 IU. Whereas a recent large-scale study from Germany recommends a much higher range. That’s why it’s best to discuss your Vitamin D needs with your healthcare provider, who has the full overview of your personal needs.

  • What is a healthy range for Vitamin D?

    There is some debate about the optimal level of Vitamin D in the blood. For example, a study from the Boston University School of Medicine found a range of 40-60 ng/ml was needed to achieve the full range of health benefits conferred by Vitamin D. And another study from the University of California, found that a slightly higher range of 60-80 ng/ml was associated with even greater benefits. But ultimately, your optimal levels will depend on your current health status and health goals.

  • What are the main benefits of Vitamin D?

    Supplemental Vitamin D is associated with a range of benefits, including improved immune health, bone health, and emotional well-being.

  • What are the symptoms of Vitamin D deficiency?

    Most people with Vitamin D deficiency don’t notice any symptoms. That’s why it’s important to get tested. However potential signs of Vitamin D3 deficiency include muscle and bone pain, heightened sensitivity to pain, a tingling sensation in the hands or feet (often described as "pins-and-needles"), muscle weakness in areas close to the body's core such as the upper arms or thighs, a waddling gait caused by muscle weakness in the hips or legs, a history of previous bone fractures, muscle twitches or tremors, and muscle spasms.

  • What are the main benefits of Vitamin K2 and K1?

    Vitamin K2 plays a critical role in maintaining optimal bone health by supporting bone metabolism and mineralization. It activates osteocalcin, a protein responsible for binding calcium to the bone matrix, which enhances bone strength and reduces the risk of fractures, osteoporosis, and age-related bone loss. Additionally, Vitamin K2 helps regulate calcium distribution throughout the body, preventing calcium from accumulating in arteries and soft tissues. Directing calcium towards the bones and teeth instead, it supports cardiovascular health, reducing the risk of arterial calcification and cardiovascular disease. Furthermore, Vitamin K2 promotes dental health by facilitating proper mineralization of teeth and preventing tooth decay. It also shows potential benefits for cognitive function, as studies suggest it may protect against cognitive decline. Lastly, Vitamin K2 possesses antioxidant properties that help combat free radicals. By modulating oxidative stress, Vitamin K2 contributes to overall health and well-being. Whereas Vitamin K1, or phylloquinone, plays a vital role in blood clotting, bone health, cardiovascular health, and acts as an antioxidant.

  • What are the main benefits of Vitamin A?

    Vitamin A plays a crucial role in maintaining various aspects of our health. When it comes to vision, it is essential for the production of rhodopsin, a protein found in the retina that is necessary for low-light and color vision. By ensuring adequate intake of Vitamin A, we can prevent night blindness, promote healthy eyesight, and reduce the risk of age-related macular degeneration. Additionally, Vitamin A supports a strong immune system by facilitating the normal development and functioning of immune cells, enhancing our ability to fight off infections. It also contributes to skin health by promoting cell turnover, and collagen production, and acting as an antioxidant, protecting the skin from damage and reducing signs of aging.

  • What are the main benefits of Vitamin E?

    Vitamin E offers a range of important health benefits. Primarily known for its potent antioxidant properties, it helps protect against cellular damage caused by free radicals. When it comes to the skin, Vitamin E plays a vital role by moisturizing and nourishing the skin, aiding in wound healing, and combating the signs of aging. Moreover, Vitamin E supports a healthy immune system by enhancing the function of immune cells and bolstering our defenses against infections and illnesses. In terms of heart health, Vitamin E's ability to prevent the oxidation of LDL cholesterol (commonly referred to as "bad" cholesterol) can reduce the formation of arterial plaque, thus lowering the risk of heart problems. Additionally, Vitamin E contributes to eye health by shielding the eyes' cells from oxidative damage, potentially reducing the risk of age-related macular degeneration (AMD), a common cause of vision loss in older adults. Furthermore, emerging research suggests that Vitamin E may have a protective effect on cognitive function and help reduce the risk of cognitive decline. Overall, Vitamin E's antioxidant activity and various health benefits make it a valuable nutrient for maintaining overall well-being.
