What is Suntrex D3?

Suntrex D3 is a premium quality vitamin D3 nutritional supplement. It’s produced by extracting oil from hearty, nutrient-dense plants known as lichens. Every batch is analyzed to verify purity and D3 content.

Lichen sourced D3 is recognized by the Vegan Society as the one form of D3 suitable for vegans. It’s completely free of toxins and allergens and contains no yeast, wheat, soy, milk, salt, sugar, preservatives or artificial colors. Simply put, if you want the best, this is it.

Whether you’re vegan, vegetarian, or simply prefer a high quality vitamin D3 supplement, Suntrex D3 is the answer!


The History and Invention of Suntrex D3

“Suntrex D3 is the result of our pursuit for 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 1ml. 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 minimizes 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.

Frequently Asked Questions

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.


Excellent Safeguard

I got this because it was ‘winter’ and I had not been in the sun to get my body to make vitamin D. I feel better, happier and healthier when I have enough vitamin d in my system. This has been a great addition to my supplements.

As a person living in a state (WA) which is overcast or cloudy 2/3 of the year I found this product extremely helpful. I can literally tell the difference in how I feel when I don’t get enough sun (moved from south) and I can tell that Suntrex is potent and effective. Very nice! I honestly feel more mentally stable and my mood is elevated.

Suntrex D3 Review
I live in sunny CA, so I was surprised when my Dr. Said I had a vitamin D deficiency which explained my lack of energy and focus. I wanted a pure form of vitamin D, so I purchased Suntrex D3. I now take Suntrex D3 daily it is part of my healthy routine. My energy level and focus has improved!

Works quickly

I have tried Vitamin D pills, oils and even trans-dermal creams and lotions over the last several years at the advice of my doctor. The D3 pills gave me a headache and I could never tell if the creams and lotions were doing anything. Within a week of using Suntrex D3, I noticed that my mood had improved and I was feeling more motivated. I am actually getting things accomplished and enjoying my day. The D3 in this product is more easily absorbed into the body. Thank you.

Worked great to get my D levels up!

My D levels were at 18 and after I finished one bottle (over a 2 month period) my levels went up to 34! I’m going to keep taking it until I get to 60… Would definitely recommend it.

Love this product!

I have been anxiously waiting for Dr Group to release the D3. I’ve only been taking it for a few weeks but have noticed I’m now sleeping through the night when before I would wake up and toss and turn for an hour or more. I also seem to be more alert. Can’t wait to see the improvements as I take it for a longer period of time. I would definitely recommend the D3 to everyone!
