The Vegan Society recognizes lichen-sourced D3 as the form of D3 most suitable for vegans. Suntrex D3 is completely free of allergens, yeast, wheat, soy, milk, salt, sugar, preservatives, and artificial colors.

The History and Invention of Suntrex D3

"There are many vitamin D supplements, but most contain weak forms of vitamin D2, and very few are vegan. Even most of the "vegetarian" vitamin D supplements are sourced from sheep's wool. This void led us to create Suntrex D3 — the best vegan vitamin D3 formula available. Each serving has 5,000 IU of lichen-derived D3 suspended in organic vegetable glycerin for fast absorption and maximum bioavailability."
-Dr. Edward F. Group III, DC, NP

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

1. What is vitamin D?

Vitamin D supports many functions in the body, and getting enough is essential for good health. Among its many duties, vitamin D is an essential nutrient that helps the muscles, teeth, bones, and immune system. It's required for us to produce the enzymes and proteins our bodies need to function correctly. In fact, all tissue in the body, including the brain and heart, has vitamin D receptors.

2. How do we get vitamin D?

Although vitamin D can be obtained naturally through sun exposure or food, those sources usually fall short of fulfilling our daily needs. There aren't many foods high in vitamin D, and the Vitamin D Council advises that diet alone isn't sufficient. As fears of skin cancer have increased, sun exposure has decreased. A supplement like Suntrex D3 is widely considered the most reliable way to meet your vitamin D requirements.

3. Why is D3 superior to D2?

There are two types of vitamin D supplements: vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol). Vitamin D3 is the form naturally made by your body after sunlight exposure. Vitamin D2 is sourced from plants or manufactured in a laboratory and not nearly as effective or biologically active. After reviewing the research and consulting experts, we've concluded that vitamin D3 is the better choice.

Frequently Asked Questions about Suntrex D2

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, vitamin D deficiency is a very real possibility.

What are the symptoms of vitamin D deficiency?

Symptoms include muscle weakness, joint aches and discomfort, high blood pressure, inability to concentrate or focus, bladder issues, constipation, headaches, immune system decline, and mood disorders.

Why aren't dietary sources adequate?

There 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?

Although a vegan diet itself may not provide the vitamin D you need, taking Suntrex D3 as recommended can. This means there's no reason to take more than directed. Consult your healthcare provider, who is familiar with your needs, before doing so.

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.

Shouldn't your D3 contain K2 and some magnesium to have better absorption?

In our experience, vitamin K assists in the delivery of calcium to the bone; however, it is not directly needed in the absorption of vitamin D3. Because of this, Suntrex D3 only contains vitamin D3. Also, since most vitamin K2 comes from soy, we believe the better alternative to consider is vitamin K1, often found in green leafy vegetables, Brussels sprouts, and cabbage. So, in a nutshell, it may help to take the calcium/magnesium supplement IntraCal and Suntrex D3 (vitamin D3) with a balanced diet of vegetables like mentioned above to get your vitamin K.

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.
