The History and Invention of Suntrex D3

Dr Group
Dr. Edward F. Group III, DC, NP

"Suntrex D3 is the result of our pursuit of the best vegan source of vitamin D3. Although there are many vitamin D supplements on the market, most are vitamin D2, which is inferior to vitamin D3, and very few are truly vegan-friendly. In fact, even most "vegetarian" forms of vitamin D are sourced from sheep lanolin. This need prompted our journey to create the most powerful, vegan, vitamin D3 product on the market. We located a vegan source of D3, extracted from lichen, and pioneered research to combine it with USP vegetable glycerin to provide 2000IU of D3 per 10 drops. This research and development took over two years but the result, as verified by independent laboratories like Stirling University, is the best, vegan, vitamin D3 product in the world."

The Top 5 Reasons You Need Suntrex D3

1. Immune System Support

People with more sunlight exposure have been found to have stronger immune system function than people with limited exposure. Why? Vitamin D3 receptors exist on immune cells and promote healthy immune cell maturity, differentiation, and integration.

2. Organ Health

Optimum vitamin D3 blood levels support healthy breasts, colon, kidneys, lungs, stomach, pancreas, bladder, prostate, and uterus. Additionally, adequate vitamin D3 promotes healthy blood vessels and may reduce swelling.

3. Bone Health

Vitamin D supports calcium absorption and research suggests that coupling vitamin D3 supplementation with calcium supplementation promotes bone strength. Furthermore, it helps to minimize urinary calcium loss.

4. Nervous System Support

Research indicates vitamin D may support healthy nerve conduction potential and neuronal calcium regulation. A 2006 study involving 7 million U.S. military personnel and published in the JANA reported that high circulating blood levels of end-chain vitamin D3, 25-hydroxyvitamin D, were associated with nerve and myelin health.

5. Brain Health

Not only does vitamin D3 promote a healthy mood, but vitamin D receptors are located in the area of the brain responsible for memory and cognition.

What are the Top 3 Questions People Ask About Vitamin D3?

1. What is vitamin D? Vitamin D is necessary for many functions in the body and although it's called a vitamin, its action is more similar to a hormone. Among its many duties, vitamin D enhances muscle strength, supports teeth and bones, and it's great for the immune system. It helps produce the enzymes and proteins necessary for our bodies to function properly. In fact, every tissue in the body, including the brain, heart, muscles and immune system, has vitamin D receptors. There's no question that maintaining adequate vitamin D levels is absolutely essential for good health.

2. How do we get vitamin D? Although there are a few dietary sources with low amounts of vitamin D, that, at best, may satisfy 10% of your vitamin D needs, the Vitamin D Council advises that diet alone is not enough for adequate vitamin D. Sun exposure causes our bodies to produce vitamin D but as skin cancer fears have increased, sun exposure has decreased. Other factors like geographic location, time of year, sunscreen, and skin exposure all influence how much vitamin D is produced. The most reliable way to meet your vitamin D requirements is supplementation.

3. Why is D3 superior to D2? When searching for a vitamin D supplement, you'll have two choices -- vitamin D3 or vitamin D2. Vitamin D3 is the form naturally manufactured by humans from sunlight exposure. Vitamin D2 is sourced from plants and not nearly as biologically active or effective. After reviewing the research and consulting experts, we've absolutely concluded that vitamin D3 is the better choice.

Who should take vitamin D supplements?

Everyone should be aware of vitamin D deficiency and most people can take vitamin D supplements without issue. However, if you're taking heart medication, have hyperparathyroidism, Hodgkin’s or non-Hodgkin’s lymphoma, a granulomatous disease, high blood calcium levels, kidney stones, kidney disease, liver disease, or hormonal disease, you should consult your healthcare specialist before adding a vitamin D supplement to your nutritional regimen.

How common is vitamin D deficiency?

Vitamin D deficiency can affect anyone, from newborns to the elderly. Dietary sources are few and inadequate. Without adequate sun exposure, which most people do not get, it's a good idea to take a vitamin D supplement.

Why aren't dietary sources adequate?

There just aren't many foods that offer a significant amount of vitamin D. The main sources are salmon, mackerel, bluefish, tuna, fortified milk, baby formula, cereal, and orange juice.

Is cod liver oil is a good source of vitamin D?

Cod liver oil does contain vitamin D but it also contains large amounts of vitamin A. Vitamin A antagonizes the action of vitamin D and too much can be toxic. The Vitamin D Council warns against taking cod liver oil for this reason.

I'm a vegan, should I take more vitamin D3 than recommended?

Not necessarily, you should just be aware that your dietary choices may make it more difficult for you to get enough vitamin D3. Before taking more than directed, we recommend consulting with your healthcare advisor who is familiar with your personal situation.

Can a person take too much vitamin D?

Yes, too much vitamin D can result in vitamin D toxicity. Indications of vitamin D toxicity include nausea, vomiting, constipation, weakness and weight loss. It can also coincide with dangerously high calcium levels that may produce kidney stones, confusion, and abnormal heart rhythms. The Vitamin D Council recommends adults do not exceed the upper limit of 10,000 IU/day.

How can I check my vitamin D levels?

Talk to your doctor about having a blood test to measure 25-hydroxy-vitamin D levels. Make sure they do not order a test for 1,25-dihydroxy-vitamin D, as this is a common error.
