Source Naturals Vitamin D-3 Bioactive Form - 2 oz. (59 mL)

Source Naturals Vitamin D3 Bioactive Form is a bioactive form for bone and immune health. New research indicates that modern indoor lifestyles may lead to a widespread increase in vitamin D deficiency. Scientists are discovering that vitamin D is an important hormone precursor that supports immune response and helps regulate the health of at least 20 different tissues, including the nervous system and joints. Source Naturals Vitamin D-3 also plays an important role in regulating cell growth, insulin levels, and bone formation.

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.

Vitamin D-3 Addresses the Following Body Systems:

Cells/DNA
It is well known that our genes, consisting of DNA, hold the information codes for all of our unique traits, and they regulate all of the structure and function of our tissues and organs. Encoded in the DNA, and "turned on" by hormones or other messengers, are the mechanisms that produce the proteins, enzymes, and other compounds that the cell uses to carry out its differentiated functions. Even though each cell contains every gene for all bodily and mental functions, each cell has the ability to activate only those specific genes needed for that cell’s specific function; the other genes remain silent or inactive. Various nutrients, plant extracts, and biochemical compounds can be seen as messengers. We can literally send instructions to our genes to perform healthy activities such as increase memory, burn fat, strengthen an immune response, or turn off gene expression that is detrimental to our health.

Inflammation Response
Inflammation is for many an underlying biochemical imbalance that can lead to concerns about our health. Inflammation begins as a helpful part of the immune system’s defense, but the problem for our health is when this natural defense process doesn’t turn off. Because of various environmental triggers and lifestyle factors, such as pollution, stress, or nutrient-deficient junk food diets, the defense system stays on the attack, generating metabolic inflammation and damaging healthy cells and tissues. Our body goes to war with itself. The fire of inflammation, however, can be quenched with dietary, lifestyle and nutritional changes.

Sugar Regulation
Our modern, “on the go” diet of processed, unnatural junk foods is overwhelming our bodies. Drastic increases in refined carbohydrates and sugars have led to health concerns unheard of even a generation ago. Increased blood glucose can lead to excess body weight and inefficient use of insulin... all are part of a spiraling, self-perpetuating cycle that is highly challenging to health. Through this cycle, increased blood sugar can lead to reactions like inflammation and glycation. Excess inflammation is an underlying imbalance that can affect cells and tissues and lead to concerns about our health. Glycation occurs when excess blood sugar binds with protein to produce Advanced Glycation End-products (AGEs), compounds that impact healthy cells. Many nutritional supplements can increase insulin efficiency and help maintain blood sugar in a normal range.

Metabolism/Hormones
At any moment, millions of biochemical reactions are taking place in or around our nearly 100 trillion cells. To function at high levels of health, our metabolism is constantly binding molecules together and breaking them apart. In a way, our health is a function of the ease, speed, and coordination of these myriad reactions, processes named methylation, acetylation, phosphorylation, and sulfation. Hormones are messengers that tell the body to begin its various physiological activities, such as growth or sexual development. Hormones are produced in our glands and are often triggered by the brain. They are part of the intricate mechanism that makes us humans with unique personalities.

Through phospholipids such as omega-3 or omega-6 in the membrane of the cell, the hormones transfer important messages to the nucleus of the cell where the DNA produces the proteins and enzymes needed to carry out the brain's desires. With age, as metabolism slows, can come a loss of effective function, which in turn can lead to a multitude of problems associated with aging. By proactively supporting metabolic and hormonal processes you can maintain youthful activity within your body.

Cognition/Nerves
The human brain is the most complex structure known to man; much of how it functions and enables us to think, feel, contemplate abstract concepts, plan our future, and control many bodily processes is yet to be discovered. The function of the brain and nervous system is based on the unique structure of nerve cells (also called neurons), which take in and send out messages in the form of electrical impulses running through the phospholipids and minerals of the cell membranes. Although it is only two percent of our body weight, the brain consumes 20 percent of our energy. Neurotransmitters, brain chemicals that pass messages from one neuron to another, must be produced in adequate quantities to support mood, intelligence, concentration, assertiveness and calmness. This creates a tremendous need for nutritional fuel and energy. Brain functioning can be significantly improved by the right quantity and quality of nutrients.

Immune
During the Plague of the 14th century, one-third of the population of Europe died. The question is: why did the others live, even though they were also exposed to the Yersinia pestis bacteria? The answer may be the strength and responsiveness of their immune systems. The immune system is like an intelligent second brain with the unique ability to identify foreign compounds and to quickly produce the specific defenses needed to combat harmful invaders and protect us. The immune system uses a wide variety of cells and biochemicals located primarily in the blood stream and the gastrointestinal tract, such as T-cells, B-cells, macrophages, and Natural Killer cells. We can significantly strengthen and improve the functionality of the immune system through nutrition, supplements and lifestyle modifications.

Structure/Connective Tissue
Our bodies are a stunning organization of various types of connective tissues. In the form of cartilage and bones, they uphold our bodies; in the form of joints, they allow our mobility; in the form of epidermal tissues - the skin - they form the body’s mass and protect us from and connect us to, our environment. As we age, many people experience calcium deficiencies and bone problems. Similarly, joint problems are among the most debilitating aspects of aging. Yet with the proper nutrients and lifestyle changes, the bones and joints can remain strong, flexible, and active well into old age. Likewise, healthy, beautiful skin is a matter of diet and nutrition: the skin should be nourished with fatty acids, antioxidants, and vitamins, and a nutritious diet gives the skin sufficient nutrients and antioxidants for protection.

About Source Naturals

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.
