LifeSource Vitamins Vitamin D-3 Gummies are perfect for those adults who want a different and fun way to take their vitamins. If you don’t like swallowing pills, these are for you. They taste great and are a great way to ensure you are getting an adequate intake of this key nutrient your body needs.

Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism. Vitamin D3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to Ultraviolet-B (UVB) radiation from sunlight or it can be obtained from the diet. Plants synthesize vitamin D2 (ergocalciferol), which also has vitamin D activity in humans. When exposure to UVB radiation is insufficient for the synthesis of adequate amounts of vitamin D3 in the skin, adequate intake of vitamin D from the diet is essential for health.*

LifeSource Vitamins Vitamin D-3 Gummies supply this key vitamin in a highly-absorbable gummy form. Vitamin D is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun. However, it is not abundant in food. As more and more people avoid sun exposure, as they should, Vitamin D supplementation becomes even more necessary to ensure that your body receives an adequate supply. This product can be used in combination with our Vitamin A and all Calcium supplements.*

FACT: Vitamin D3 influences over 3,000 genes in our body!

Here are a few:

Vitamin D is used for - WebMD States

• treating weak bones – osteoporosis*
• bone pain – osteomalacia*
• bone loss in people with a condition called hyperparathyroidism*
• inherited disease (osteogenesis imperfecta) in which the bones are especially brittle and easily broken*
• It is also used for preventing falls and fractures in people at risk for osteoporosis, and preventing low calcium and bone loss (renal osteodystrophy) in people with kidney failure*

Vitamin D is also used for conditions of: WebMD States

• Heart and blood vessels*
• High blood pressure*
• High cholesterol*
• Diabetes*
• Obesity*
• Muscle weakness*
• Multiple sclerosis*
• Rheumatoid arthritis*
• Chronic obstructive pulmonary disease (COPD)*
• Asthma*
• Bronchitis*
• Premenstrual syndrome (PMS)*
• Tooth and gum disease*

WebMD States: Some people use vitamin D for skin conditions including vitiligo, scleroderma, psoriasis, actinic keratosis, and lupus vulgaris.

It is also used for boosting the immune system and preventing autoimmune diseases.*

Because vitamin D is involved in regulating the levels of minerals such as phosphorous and calcium, it is used for conditions caused by low levels of phosphorous (familial hypophosphatemia and Fanconi syndrome) and low levels of calcium (hypoparathyroidism and pseudohypoparathyroidism).*

How does it work?

Vitamin D is required for the regulation of the minerals calcium and phosphorus found in the body. It also plays an important role in maintaining proper bone structure.*

Sun exposure is an easy, reliable way for most people to get vitamin D. Exposure of the hands, face, arms, and legs to sunlight two to three times a week for about one-fourth of the time it would take to develop a mild sunburn will cause the skin to produce enough vitamin D. The necessary exposure time varies with age, skin type, season, time of day, etc.*

It’s amazing how quickly adequate levels of vitamin D can be restored by sunlight. Just 6 days of casual sunlight exposure without sunscreen can make up for 49 days of no sunlight exposure. Body fat acts like a kind of storage battery for vitamin D. During periods of sunlight, vitamin D is stored in fatty fat and then released when sunlight is gone.*

Nevertheless, vitamin D deficiency is more common than you might expect. People who don’t get enough sun, especially people living in Canada and the northern half of the US, are especially at risk. Vitamin D deficiency also occurs even in sunny climates, possibly because people are staying indoors more, covering up when outside, or using sunscreens consistently these days to reduce skin cancer risk.*

Older people are also at risk for vitamin D deficiency. They are less likely to spend time in the sun, have fewer “receptors” in their skin that convert sunlight to vitamin D, may not get vitamin D in their diet, may have trouble absorbing vitamin D even if they do get it in their diet, and may have more trouble converting dietary vitamin D to a useful form due to aging kidneys. In fact, the risk for vitamin D deficiency in people over 65 years of age is very high. Surprisingly, as many as 40% of older people even in sunny climates such as South Florida don’t have enough vitamin D in their systems.*

Vitamin D supplements may be necessary for older people, people living in northern latitudes, and for dark-skinned people who need extra time in the sun, but don’t get it.


What symptoms can indicate a need for more vitamin D?

• Bone pain and/or soft bones
• Frequent bone fractures
• Bone deformities or growth retardation in children
• Lack of exposure to sunlight for any reason, including geography, use of sunscreen, or wearing of protective clothing

Depression: Vitamin D3 deficiency is common in older adults and has been implicated in psychiatric and neurologic disorders. For example, in one study of 80 older adults (40 with mild Alzheimer’s disease and 40 nondemented persons), Vitamin D3 deficiency was associated with low mood and with impairment on two of four measures of cognitive performance.

Wilkins CH, Sheline YI, Roe CM, Birge SJ, Morris JC. Vitamin D deficiency is associated with low mood and worse cognitive performance in older adults. Am J Geriatr Psychiatry. 2006 Dec;14(12):1032-40.

Musculoskeletal disorders : Has been linked to Vitamin D3 deficiency in a number of studies. One of the newest studies explored the role that low Vitamin D3 levels play in the development of chronic low back pain in women. Sixty female patients in Egypt complaining of low back pain lasting more than three months were studied. Researchers measured levels of Vitamin D3 in the women with low back pain and compared those levels to those of 20 matched healthy controls.

The study revealed that patients with low back pain had significantly lower Vitamin D3 levels than controls. Low Vitamin D3 levels (25 OHD < 40 ng/ml) were found in 49/60 patients (81 percent) and 12/20 (60 percent) of controls.

Cognitive Enhancement: One of the best known and long-established benefits of Vitamin D3 is its ability to improve bone health and the health of the musculoskeletal system. It is well documented that Vitamin D3 deficiency causes osteopenia, precipitates and exacerbates osteoporosis, causes a painful bone disease known as osteomalacia, and exacerbates muscle weakness, which increases the risk of falls and fractures. Vitamin D3 insufficiency may alter the regulatory mechanisms of parathyroid hormone (PTH) and cause a secondary hyperparathyroidism that increases the risk of osteoporosis and fractures.

Most recently, low Vitamin D3 levels have been linked to an increased prevalence of early age-related macular degeneration.

Why is D3 preferred?

There are two main options to supplement with Vitamin D. D2 (ergocalciferol) is produced from irradiated fungi in a laboratory. D-3 (cholecalciferol) is the form typically extracted from fish oil or food sources. Due to the manufacturing process, it seems that D2 has been associated with more potential side effects, and has greater risks for toxic contamination. D-3 matches what is produced by human skin, and is much more efficiently converted by the liver to support circulating active levels of 25-HydroxyVitamin D. Potency and quality are key in D-3 supplement choice, and only pharmaceutical grade products are held to consistent content and quality standards. While some studies and pharmaceutical companies use D2 supplements, we believe there is strong evidence to use D-3.


Risk Factors for Vitamin D Deficiency

Exclusively breastfed infants: Infants who are exclusively breastfed and do not receive vitamin D supplementation are at high risk of vitamin D deficiency, particularly if they have dark skin and/or receive little sun exposure. Human milk generally provides 25 IU of vitamin D per liter, which is not enough for an infant if it is the sole source of vitamin D. Older infants and toddlers exclusively fed milk substitutes and weaning foods that are not vitamin D fortified are also at risk of vitamin D deficiency. The American Academy of Pediatrics recommends that all infants that are not consuming at least 500 ml (16 ounces) of vitamin D fortified formula or milk be given a vitamin D supplement of 200 IU/day.

Dark skin: People with dark skin synthesize less vitamin D on exposure to sunlight than those with light skin. The risk of vitamin D deficiency is particularly high in dark-skinned people who live far from the equator. In the U.S., 42% of African American women between 15 and 49 years of age were vitamin D deficient compared to 4% of White women.

Aging: The elderly have a reduced capacity to synthesize vitamin D in the skin when exposed to UVB radiation, and are more likely to stay indoors or use sunscreen. Institutionalized adults are at extremely high risk of vitamin D deficiency without supplementation.

Covering all exposed skin or using sunscreen whenever outside: Osteomalacia has been documented in women who cover all of their skin whenever they are outside for religious or cultural reasons. The application of sunscreen with an SPF factor of 8 reduces production of vitamin D by 95% (1).

Fat malabsorption syndromes: Cystic fibrosis and cholestatic liver disease impair the absorption of dietary vitamin D.

Inflammatory bowel disease: People with inflammatory bowel disease like Crohn’s disease appear to be at increased risk of vitamin D deficiency, especially those who have had small bowel resections.

Obesity: Obesity increases the risk of vitamin D deficiency. Once vitamin D is synthesized in the skin or ingested, it is deposited in body fat stores, making it less bioavailable to people with large stores of body fat.

The Recommended Daily Allowance (RDA) for vitamin D as determined by the Food and Nutrition Board is presently under scrutiny by researchers and scientists who believe that the current suggested RDA for vitamin D of 200-600 IU (International Units) is far too low and should be raised to at least 1,000 I.U. Many researchers believe that in order to achieve maximum benefit from vitamin D, doses may need to be between 3,000-5,000 I.U per day until blood levels are maintained at ideal, with regular monthly blood testing for safety during that process.

Please see your doctor if using higher dosage supplementation for repeated vitamin D and calcium blood tests. Rarely, an individual may ingest too much vitamin D which puts them at risk for a reaction from vitamin D hypersensitivity. Symptoms of hypersensitivity or toxicity may include serious stomach upset accompanied by vomiting and excessive thirst. If you suspect vitamin D toxicity when using supplements, you should contact your doctor immediately. New studies seem to indicate that vitamin D toxicity is highly unlikely for most healthy individuals using even up to 6000 IU’s of D-3 daily, unless suffering from an underlying kidney or metabolic condition which affects serum calcium levels.

Dec. 19, 2006 -- There is new evidence supporting the idea that vitamin D helps prevent multiple sclerosis, but it is too soon to recommend taking the vitamin to lower your risk, researchers say.

In the first large-scale study to examine the issue, researchers from the Harvard School of Public Health reported a strong association between vitamin D levels within the body and MS risk among whites, but not among blacks and Hispanics.
The study is published in the Dec. 20 issue of The Journal of the American Medical Association.

Senior researcher Alberto Ascherio, MD, DrPH, tells WebMD that roughly half of white Americans and two-thirds of black Americans could be considered to have insufficient levels of vitamin D. Because exposure to sunlight is a major source of the vitamin for most people, vitamin D levels are usually lowest in the wintertime.

"Our findings suggest that vitamin D may have a direct impact on multiple sclerosis risk," Ascherio says. "If we confirm that the vitamin is protective, we could potentially prevent thousands of cases of MS a year in The United States alone."

Some 350,000 new cases of multiple sclerosis are diagnosed in the U.S. annually, and chronic autoimmune disease is more common among women than men. In earlier studies, Ascherio and Harvard colleagues reported that women who took multivitamins with at least 400 international units (IU) of vitamin D appeared to have a lower risk of MS than women who did not.

Their newest study involved a study population of more than 7 million members of the U.S. Army and U.S. Navy with blood samples stored in a Department of Defense repository.
Between 1992 and 2004, 257 people were diagnosed with MS. Each case was compared to two people without MS matched for age, race, sex, and dates of blood collection.

Sept. 14, 2006 — There's not a lot of good news in the fight against pancreatic cancer, the fourth most common cause of cancer deaths in The United States.

The disease, often aggressive and fatal, is difficult to treat with standard cancer treatments.
Scientists from Northwestern and Harvard University, however, have found a possible important link between vitamin D and pancreatic cancer.

In two studies, researchers tracked more than 120,000 men and women from 1986 to 2000.

They compared how much vitamin D the men and women ate to the number of cases of pancreatic cancer.

There were 365 cases of pancreatic cancer over the 16-year span. Researchers found that patients who had consumed high levels of vitamin D were 41 percent less likely to develop pancreatic cancer when compared with people with low vitamin D diets.

From these findings, the researchers conclude that vitamin D may have some role in the prevention of pancreatic cancer, possibly as a type of tumor-fighting vitamin that keeps cancers from growing and multiplying. Thankfully, vitamin D is not hard to find.

It is found in many foods, and skin naturally makes vitamin D when exposed to sunlight. It also may fight off more cancers than just this one.

“I’ve been converted from a skeptic about a role of vitamin D in preventing cancer to a believer that there’s something there,” said Dr. Len Lichtenfeld, deputy chief medical officer for the American Cancer Society.

Lichtenfeld said there should be more study of the link between the vitamin and cancer, but the research is at an early stage.

Researchers Call for Higher Doses

In an editorial in the March 2007 edition of the American Journal of Clinical Nutrition, a prominent group of researchers from leading institutions such as the University of Toronto, Brigham and Women’s Hospital, Tufts University and University Hospital in Zurich, Switzerland, lashed out at the conventional media for its inaccurate reporting of Vitamin D supplementation.

The researchers wrote, “Almost every time the public media report that Vitamin D nutrition status is too low, or that higher Vitamin D intakes may improve measures of health, the advice that accompanies the report is outdated and thus misleading. Media reports to the public are typically accompanied by a paragraph that approximates the following: ‘Current recommendations from the Institute of Medicine call for 200 IU/day from birth through age 50 years, 400 IU for those aged 51–70 years, and 600 IU for those aged >70 years. Some experts say that optimal amounts are closer to 1,000 IU daily. Until more is known, it is wise not to overdo it.’ The only conclusion that the public can draw from this is to do nothing different from what they have done in the past.”

The researchers point out that supplemental intake of 400 IU per day barely raises blood concentrations of 25(OH)D, which is the circulating Vitamin D metabolite that serves as the most frequently measured indicator of Vitamin D status. To raise 25(OH)D from 50 to 80 nmol/L requires an additional intake of 1,700 IU Vitamin D per day.

The researchers went on to write that, “The balance of the evidence leads to the conclusion that the public health is best served by a recommendation of higher daily intakes of Vitamin D. Relatively simple and low-cost changes, such as increased food fortification or increasing the amount of Vitamin D in Vitamin supplement products, may very well bring about rapid and important reductions in the morbidity associated with low Vitamin D status.”

One of the challenges is the outdated acceptable upper limit for Vitamin D3 consumption, which was set at 2,000 IU. However, researchers point out that more recent studies have shown that 10,000 IU is the safe upper limit.

Dr. R. Vieth, one of the foremost authorities on Vitamin D3 supplementation has extensively studied Vitamin D, and lamented the low requirements for Vitamin D3 in a recent issue of the Journal of Nutrition: “Inappropriately low UL [upper limit] values, or guidance values, for Vitamin D have hindered objective clinical research on Vitamin D nutrition; they have hindered our understanding of its role in disease prevention, and restricted the amount of Vitamin D in multivitamins and foods to doses (that are) too low to benefit public health.”

When examining the medical literature, it becomes clear that Vitamin D3 affects human health in an astonishing number of ways and that not obtaining enough of this important nutrient can leave the door open to developing a number of health conditions.

Vitamin D & Weight Loss Information

Vitamin D, or the sunshine vitamin, was recently featured in over 3,000 independent clinical studies conducted all over the world in last year alone. After the medical results were tallied and evaluated, Vitamin D is now the superstar in the weight loss supplement industry.

Vitamin D, a natural hormone produced by the body when exposed to sunlight or acquired through diet and supplementation, was shown to play a critical role in increasing the metabolic energy of fat cells faster weight loss benefits.

While still early in its literature, the new scientific research on Vitamin D revealed its natural ability to make fat cells become more metabolically active for quicker weight loss and better toxic waste elimination.

In light of the new clinical data being presented on Vitamin D for weight loss, it has already been known to help support a healthy bone structure and aid in several health challenges like:

• targets belly fat first*
• turns body into fat-burning mode instead of fat-storing mode*
• high blood pressure*
• helps form stronger bones to fight osteoporosis*
• helps protect against different cancers*
• boosts natural immune system*
• reduces inflammation & joint stiffness*
• Helps the I’m full to brain’ leptin hormone*
