    Dr. Cooper personally recommended this supplement to me while I was a patient of his. Then, my wife’s doctor also made the same recommendation and endorsed the Cooper brand. We are both quite pleased.

    We are disappointed that the new label does not say Vitamin D-3 on it. It says only Vitamin D. It is confusing since I ordered Vitamin D-3. I am just have to assume that I have the right vitamins now.

    • Thank you for your feedback. When we introduced our new labels we wanted to make them less cluttered and easier to read so we removed the “3” from the description. The D-3 form of Vitamin D is cholecalciferol, which is what is listed on our nutrition facts portion of the label. So we have not changed the product, it is still vitamin D3, just listed in a different format. Based upon your feedback and comments from other customers, we are looking at revising future labels back to specifically state vitamin D3 to avoid any confusion.

    As someone who has osteopenia, precursor to osteoporsis, and someone 77 years of age, it’s vital that I take both calcium and Vitamin D supplements. I’ve been taking Cooper Complete versions of these for many years. I trust the brand because of its high standards.

    I love the fact that such a tiny pill has such a high IU factor.

    One of my greatest 2014 test results is that my BMD in my spine has actually increased over the past two years, and in my hip there has been no statistically significant decrease. I credit this to the Cooper Complete Calcium Citrate and Cooper Complete Vitamin D-3 supplements, with weight-bearing, resistance and strength building exercises. I work very hard and consistently to avoid bone loss, although I know some loss is inevitable with age. Of course, I do not, nor have I ever, taken any medications for bones!!

Frequently Asked Questions

Should I take Vitamin D3 softgels with or without food?

Vitamin D3 softgels should be taken with food. A study published in the Journal of the Academy of Nutrition and Dietetics, Feb., 2015 found that vitamin D3 absorption increased by 32 percent when taken with a meal with 30 percent of the calories as fat.

Why is my Vitamin D level low?

There are two primary reasons why most of us lack vitamin D, according to the authors of the Archives of Internal Medicine article. The most significant factor is increased use of sunscreen. Sunscreen with a sun protection factor (SPF) of 15 decreases the synthesis of vitamin D by 99 percent. In addition, decreased outdoor activity and obesity have been associated with vitamin D insufficiency.

How do I know if I need to take supplemental vitamin D?

The only way to know your vitamin D level is to have a blood test known as 25 hydroxyvitamin D.  “Insufficiency” is generally defined by a level less than 30 ng/ml. Vitamin D “deficiency” is a level less than 20 ng/ml. “Toxicity” does not begin until your vitamin D level hits at least 150 ng/ml. Of interest, most lifeguards and people that live near the equator (where UVB light is most prevalent) have vitamin D levels around 100 ng/ml.

What causes Vitamin D deficiency?

Vitamin D levels in humans vary dramatically by season, latitude and race. Avoidance of UV exposure has led to an epidemic of low vitamin D levels. Vitamin D can be obtained through the diet, but there are very few food sources (fatty fish, cod liver oil, fortified milk and fortified cereals).

In the summer, most people will have higher levels due to intentional or unintentional sun exposure. People living in the northeastern United States are at higher risk for vitamin D deficiency due to lack of sunshine for much of the year. Darker skinned individuals are at higher risk for deficiency due to higher melanin levels in the skin that block UV absorption.

What Vitamin D level do I need to have?

The recommended target level for vitamin D is open to debate. Most experts agree your vitamin D level should be least 30 ng/ml. However, doctors at the Cooper Clinic in Dallas, Texas recommend patients target at least 40 ng/ml as a baseline. For optimal brain health, a level of 50 ng/ml is considered optimal.

How much Vitamin D do I need to take?

How much is needed varies greatly based on age, skin tone, time of year, sun exposure, where you live, weight, and other factors. Cooper Clinic suggests consulting with your physician on what your specific intake should be based on your vitamin D test results, age, and health issues.

Can Vitamin D help reduce pain cased by osteoarthritis?

A study published in The Clinical Journal of Pain found that obese individuals with knee osteoarthritis who had higher levels of vitamin D experienced less knee pain than those with deficient or insufficient levels of vitamin D. In the study of 256 middle-age and older adults with osteoarthritis, the participants provided a self-report of knee pain and completed functional performance tasks that included balancing, walking and rising from a sitting position to a standing position. The participants with healthy vitamin D levels had less knee osteoarthritis pain, and could also walk, balance and rise from sitting to standing better than obese participants with insufficient levels of vitamin D.

Has this product changed? It no longer says it is D3.

No.Our new labels feature a cleaner look so we removed the 3 from the label. The ingredient panel lists it as cholecalciferol, which is D3. D3 has been shown to be more efficient at raising 25-hydroxyvitaminD serum levels, which is the best measure of vitamin D status

Should I take this product if I am also taking Coumadin or Warfarin?

If you are taking Coumadin or Warfarin, we recommend consulting your doctor before adding any supplements to your diet.
