Source Naturals - Vitamin D-3 400 IU - 100 Tablets
Source Naturals Vitamin D-3 supports the immune system and strong bones. Sunlight is the source of life on Earth, but we may not be aware of all the ways it benefits us. Our bodies manufacture vitamin D-3 when the skin is exposed to UV radiation from sunlight, but the ability to do so decreases as we age. Vitamin D-3 maintains healthy calcium and phosphorus levels in the body for strong bones; it increases muscle strength in older adults; and it also plays an active role in a healthy immune response. Vitamin D-3 (cholecalciferol) is the optimal form of vitamin D. It is the form of vitamin D that the body manufactures in sunlight, and the form most efficient for the body's needs.
Source Naturals Vitamin D-3 Healthy Cell, Bone and Immune Support
New research indicates that our modern indoor lifestyles may lead to a widespread increase in vitamin D deficiency. Nicknamed the “sunshine vitamin” because the body makes it naturally when exposed to the sun, scientists are discovering that vitamin D-3 is an important hormone precursor that supports the immune system and helps regulate the health of at least 20 different tissues, including the brain and joints.
It also plays an important role in regulating cell growth, insulin levels and bone formation. Researchers are finding that the current recommended daily allowances of vitamin D—200 international units for infants, children and adults up to age 50 years; 400 IU for men and women from 50 to 70; and 600 IU for people older than 70—may be far lower than what is necessary for optimum health. That’s why Source Naturals offers Vitamin D-3 in 400 IU, 1,000 IU and 2,000 IU tablets; 2000 IU softgels, 5000 IU capsules, and as a convenient liquid.
Source Naturals Vitamin D-3: Total Body Vitamin
Vitamin D addresses seven of the twelve SystemiCare deep metabolic systems of the body, systems crucial to vibrant health: Cells/DNA, Inflammation Response, Metabolism, Hormones, Cognition/ Nerves, Immunity, and Structure/Connective Tissue.

Source Naturals Vitamin D research is an emerging area of interest for scientists, who have yet to understand the many roles of this important vitamin in the body. While vitamin D's main function is to maintain normal levels of calcium and phosphorus in the blood, vitamin D also serves as a hormone precursor. Once it has been converted into its active form, it can enter a cell, cross the nuclear membrane, attach to specific receptors on the DNA or its protein wrapping, and promote cell differentiation. Vitamin D is one of the body's many control systems, acting like an emergency brake to stop cells from perilously misbehaving.
The Studies of Vitamin D and Benefits:
- Important Immune and Health Booster: Two studies involving more than 200,000 American women have also highlighted the vitamin's benefits. Women who consumed the recommended daily amount of vitamin D or more were 30% to 40% less likely to have immune imbalances. Additional studies suggest that vitamin D may aid neurological health, joint comfort and function, and support healthy blood sugar levels that are within the normal range. Vitamin D decreases the production of a hormone called renin, which is believed to play a role in maintaining normal blood pressure levels. Even a person's weight is a factor: It has been found that people who are overweight do not synthesize vitamin D as well as people who are not obese, hence the need for supplementation.
- Vitamin D and Bone Health: It is estimated that over 25 million adults in the United States have, or are at risk of developing, weakened bones as they age. Having normal storage levels of vitamin D in the body helps keep bones strong, especially in elderly, non ambulatory individuals and post-menopausal women.
- Vitamin D and Blood Pressure: Vitamin D May also support healthy blood pressure. Scientists noticed that blood pressure levels vary with the season they tend to be highest during autumn and lower during the warmer months of spring summer. Researchers studied people's blood pressure and the levels of vitamin D in their blood and discovered a connection between higher vitamin D levels and decreased blood pressure. The body controls blood pressure through the renin angiotensin system with high levels leading to increased blood pressure. Cutting edge research has shown that vitamin D regulates renin levels through genetics, which may be the critical way in which this vitamin supports cardiovascular health.
Vitamin D Deficiency Is Widespread
Vitamin D is not available in most foods (oily fish, egg yolks, liver and cod liver oil have some) but is made when sunlight strikes the skin. Vitamin D insufficiency may be quite common in places far from the equator and researchers estimate that 50% of Americans may have less vitamin D than they need. Today's teens also have less exposure to direct sunlight and have switched from drinking vitamin D fortified milk to soda. Puberty is a very critical time when up to half of a person's adult bone mass is being deposited, and vitamin D helps ensure that people have normal blood levels of calcium for this important process. New research estimates that 30 percent of adolescents nationwide may be vitamin D deficient.
Deficiency Risk for African Americans
People of African descent required up to 30 minutes sun exposure three times weekly during summer on the face, arms and hands, while very fair skinned white people require 5-10 minutes. African - Americans have the highest risk for vitamin D deficiency because dark skin needs 5 to 10 times more sunlight than white skin to produce the same amount of the vitamin. One study found that 42 percent of African American women in the U.S. were vitamin D deficient. And while the use of sunscreen is imperative for skin health, sunscreen that is sun protection factor 8 (SPF 8) or greater blocks 95% if the UVB light needed for the skin to synthesize vitamin D.
Leaders of the Wellness Revolution
Source Naturals was created in 1982 by C.E.O Ira Goldberg to support each individual’s potential to enjoy optimal health. At that time, the kind of nutritional formulations he envisioned – for the maintenance of well-being and the enhancement of life – simply didn’t exist. The idea of combining many nutrients, herbs and nutraceuticals in one formulation, though common today, was then a rarity. Source Naturals pioneered the concept with Wellness Formula, now the industry’s #1 immune support product. Source Naturals subsequently introduced numerous award-winning formulas, recognized for their excellence in independent surveys and nutritional analyses. In addition to Wellness, these award-winners include Life Force Multiple, Mega-Kid Multiple, Inflama-Rest, the Skin Eternal line, Higher Mind, Essential Enzymes, Male Response, and more.
Source Naturals’ comprehensive Bio-Aligned Formulas help bring the power of alignment to your body. When formulating, Source Naturals evaluates the underlying causes of system imbalances, and then provides targeted nutrition to interdependent body systems.
