Why should I take Vitamin D3?

New research has revealed that as many as 50% of Americans are not getting enough vitamin D. It is very difficult to get enough of this important vitamin from diet alone unless you eat a lot of fish such as salmon, sardines, mackerel or herring or take cod liver oil. Vitamin D plays many crucial roles in our bodies: it helps promote calcium absorption for bone and teeth health and helps regulate white blood cells for immune system support. Absorbing enough vitamin D from sun alone may be difficult especially if you have darker skin, are older, live in a northern climate, wear sunscreen, work or stay indoors, are obese, or have trouble absorbing fats. People who have a healthy lifestyle, but avoid or limit their dairy intake (such as vegetarians) may also not be getting enough vitamin D.

What is the better form of vitamin D?

D3 is the preferable form over D2 because of its high level of biologic activity. D3 is the naturally occurring form of vitamin D that is made when your skin is exposed to sunlight.

What if I take other supplements with vitamin D in it already? How much can I have per day?

If you are taking other supplements containing vitamin D, you will need to adjust the dosage accordingly to get the right amount. It is best to check with your doctor to find out how much vitamin D you need each day. According to Office of Dietary Supplements, the tolerable upper level for Vitamin D (UL) is currently set at 2,000 IU for ages one and up, but studies have shown that an adult would need to take more than 10,000 IU per day over an extended period of time for toxicity to occur. (Source: Alternative Medicine Review - Use of Vitamin D in Clinical Practice) If you are pregnant or lactating or have a known medical condition and/or are taking medications you should consult with a healthcare practitioner before taking dietary supplements.

I have heard of a test for vitamin D levels in my body, what is it and when should I get tested?

To determine if you have enough vitamin D, a doctor will give you a blood calcidiol (25-hydroxyvitamin D) test. The optimal level of blood calcidiol is 35 to 55 ng/mL (nanograms per milliliter). Some medical scientists believe that this level should be slightly higher.

What are possible symptoms of low vitamin D levels?

Muscular weakness, a feeling of heaviness in the legs, chronic musculoskeletal pain, fatigue, depression, or easy tiring may be symptoms of vitamin D deficiency. Current research has implicated vitamin D deficiency as a factor in the pathology of many chronic illnesses.

Why does the Wellesse Vitamin D3 liquid change color over time?

Wellesse Vitamin D3 is made with natural colors that can change over time. You may see your product change from light purple to a golden apple juice color. This change does not affect product quality, potency or purity.

What is cellulose?

Cellulose is a stabilizing and emulsifying agent. It is the component of plant cell walls that gives them rigidity. When used in a liquid, it acts as a thickener and gives the product "body". It is refined from wood pulp.

Are there any animal products in Wellesse Vitamin D?

No, however, vitamin D is derived from the lanolin found in sheep's wool.

"I use the Wellesse Calcium and Vitamin D3 Liquid and the new Vitamin D3 5000 IU. I was diagnosed with osteoporosis a few years back and could not take the medication because of allergies to it. I was told to start taking Calcium and Vitamin D supplements to slow bone loss. I recently went in for a bone density test again, because of Wellesse I was told there was new growth and I now have Osteopenia and am headed in the right direction to possible complete regrowth. Test said: Since your prior study there has been a significant increase in the bone density of your spine."
