Product description

New, exciting research shows that Vitamin D has many newly discovered functions. Of course, maintaining healthy vitamin D levels is essential throughout all stages of your life. But, did you know that vitamin D receptors are found in countless tissues throughout the entire body? That can only mean that vitamin D has a much greater impact on the body’s health than we previously thought! We already knew that vitamin D was very important in helping to maintain healthy bones, bone growth, bone mineralization, and absorption of calcium. Vitamin D also supports cardiovascular system health. But now, eye-opening research shows that our immune cells have vitamin D receptors. This means that getting enough vitamin D may be critically important to support our immune system health by helping to activate immune cells.

First, the preferred form of vitamin D is D3 (not vitamin D2) because it is better metabolized by the body. Second, look for a natural source of vitamin D3 (not synthetic) with at least 1,000 mg per dose. Avoid products with undesirable chemical tagalongs such as magnesium stearate (a questionable excipient) or other chemical no-no’s.

* Natural source vitamin D3 (not synthetic)
* In a fat-soluble base (extra virgin olive oil) for better absorption
* No added magnesium stearate
* No artificial colors or flavors
* Promotes bone growth and mineralization
* Promotes absorption of calcium
* Supports cardiovascular health
* Supports immune system health
* Unparalleled Quality
* Pure Vegan
* Non-GMO

At Premier Research Labs, we never compromise on safety, efficacy or quality of any product. We go a quantum leap further by striving to produce products that are 100% excipient-free and made with solvent-free vegetable capsules.

RECOMMENDED USAGE: Take 1 drop daily with a meal or as directed by a health professional.

3.0 out of 5 stars New warning
By E. Pyer on November 15, 2017
Have been using this product for about 4 years. The package was received on time, however, this is the first time there was a sticker on the cap that read "Warning. This product contains a chemical known to the State of California to cause birth defects or other reproductive harm". What's up with this. I plan to contact the manufacturer regarding this.
