Maintains Bone Health (1)
Supports Heart Health (2)

Strengthen Immune System (4)
Facilitates Accurate Gene Expression (5)

Vitamin D-3 (as cholecalciferol) is known as the "Sunshine Vitamin" because it is formed in the body by the sun's ultraviolet rays on the skin.

Vitamin D-3 is known for its ability to build bone strength and density to aid in the prevention of bone-related diseases such as osteoporosis and rickets. In Addition to supporting Bone Health, Vitamin D-3 is involved in the biology of cells and tissues in our body and plays a vital role in many of our body's biological functions.

Vitamin D-3 Supports

Bone Health: Vitamin D-3 increases your body's ability to absorb calcium, iron, magnesium, phosphate, and zinc through your intestinal tract to support Bone Health. (1)

Heart Health: Vitamin D-3 is used by many cells in the cardiovascular system, including heart muscle cells and the cells that line blood vessels. (2)

Brain Health: Studies indicate vitamin D can lower the risk of Parkinson's disease, schizophrenia, dementia, and depression. (3)

Immune System: Vitamin D turns on essential peptides in your immune system that trigger a strong anti-microbial response, allowing you to fight off invaders before they can develop into infections effectively. (4)

Gene Expression: D-3 is converted into a hormone that is able to carry out its numerous necessary functions. D-3 activates the unwrapping of your DNA, which facilitates protein synthesis needed for human life. (5)

Low levels of Vitamin D in the blood have been linked to an increased risk of:

Cardiovascular Disease (2)
Cancer (6)
Diabetes (7)
Osteoarthritis (1)
Dementia (3)
Immune System Disorders (4)

Are You Getting Enough D-3?

An Estimated 57% of Adults in the United States have Severe Vitamin D-3 deficiencies, and in areas with minimal sun exposure, these estimates can be as high as 90%.

The Best Form of Vitamin of D-3 is Sunlight. However, most people cannot get enough exposure to sunlight to provide them with adequate levels of D-3, and living in a sunny climate does not guarantee vitamin D-3 deficiencies.

The elderly are more prone to this deficiency since their capacity to activate vitamin D in the skin is reduced as we age.

The high rates of Vitamin D-3 deficiencies in the US have prompted the FDA to increase their daily recommended allowance of D-3 from 100 IUs (International Units) per day to a daily recommendation of 400-600 IUs per day. In contrast, many doctors and health professionals recommend an average daily intake between 4000-10000 IUs of Vitamin D-3 per day.

Factors that can contribute to Vitamin D deficiencies:

Limited Sun Exposure
Increased Use of Sunscreens
Having Dark Skin
Being Overweight
Increased amounts of time spent indoors

It is important to know the level of D-3 in your blood.

When visiting your doctor ask to have D-3 added to the list of items for your blood work as it is not normally included in routine blood tests. Ideally, your level should be around 50.

Our D-3 is available in 5000 IU gelcaps and is guaranteed to meet your High-Quality Standards.

I use Boomers D3 in order to keep my infection numbers down so that my body can work on keeping my body healthy. With Type 2 diabetes you must use all defenses at your disposal. Love the whole suite of products. I feel energetic at 78 and still working. Michael
