Super D3 contains the "natural" source of Vitamin D, extracted from the lanolin of sheep wool. Vitamin D3 supports the regulation of calcium metabolism and absorption from the gut, while decreasing its excretion from the kidneys, thereby supporting the body in maintaining healthy blood levels of calcium and phosphorus.* In March 1998, the New England Journal of Medicine published the surprising results of a study by researchers from Harvard, which found a prevalence of vitamin D deficiency not only among elderly people with low vitamin D intake, but in patients less than 65 years of age without any apparent risk factors for hypovitaminosis D. Hypovitaminosis D was found in 42% of 1,546 African American women who participated in the study. Even among 243 subjects who consumed 200 IU daily from supplements, the prevalence of hypovitaminosis D was 28%. It has been estimated that as much as 40% of the U.S. population may be deficient in vitamin D, and this deficiency is prevalent in much of the world, in the young and old. It appears that vitamin D deficiency is so common because of both increasingly limited exposure to sunlight and inadequate dietary intake of vitamin D.* The primary source of vitamin D3 is sunlight, which converts 7-dehydrocholesterol in the skin to vitamin D3 via photochemical reactions using ultraviolet B radiation (UV-B). Numerous factors such as latitude, season, air pollution, pigmentation of skin, and sunscreen affect UV-ray exposure. The US is between 30 degrees and 45 degrees latitude, and six months or more of each year has insufficient UV-B sunlight to produce optimal D levels. People with dark skin produce less vitamin D since melanin, a skin pigment, acts as a natural sunscreen, absorbing UV radiation. Only a few foods naturally contain vitamin D: fatty fish, fish liver oils and eggs from hens that have been fed vitamin D. Fortified foods, such as milk and breakfast cereals, are the major sources of dietary vitamin D intake.* The term vitamin D refers to vitamin D2 and vitamin D3, as well as to their metabolites and analogues. Vitamin D2 (ergocalciferol) is derived from fungal and plant sources; vitamin D3 (cholecalciferol) is derived from animal sources. Super D3 is derived from lanolin, from sheep's wool. Vitamin D usually acts as a hormone precursor, requiring two stages of metabolism before reaching hormonal form. Following absorption or endogenous synthesis, it is metabolized to 25-hydroxycholecalciferol (25(OH)D) in the hepatocytes. 25(OH)D is the major circulating form of vitamin D, but is not biologically active. Then the biologically active hormone form, 1 alpha 25-dihydroxycholecalciferol (1,25(OH)2D), is produced in the kidneys. Vitamin D receptors exist in a wide variety of tissues and organs.* The principal direct toxic effects of too much vitamin D are excessive absorption of calcium and phosphorus from the intestine and resorption of calcium and phosphorus from bone. The prolonged ingestion of excessive amounts of vitamin D and accompanying hypercalcemia can result in metastatic calcification of soft tissues, including the kidney, blood vessels, heart and lungs. There is a wide variation among individuals in their tolerance to toxicity. In general, chronic ingestion of 50,000 IU to 100,000 IU daily of vitamin D is required to produce hypercalcemia.* The Reference Daily Intake (RDI) for vitamin D is 400 IU. The U.S. National Academy of Sciences has recommended the following adequate intakes for vitamin D: 200 IU for ages 0-50, 400 IU for ages 51-69, and 600 IU for ages greater than 70. They have also defined a tolerable upper limit intake level (UL) that is unlikely to pose risk to the general population: infants 0-12 months, 1000 IU/day; children and adults, including pregnant and lactating women, 2000 IU/day. However, some researchers argue that the RDIs and ULs are too limited. Testing of plasma 25(OH)D concentration is considered the best way to determine the level of vitamin D and to monitor vitamin D supplementation.* Vitamin D is the principal regulator of calcium homeostasis in the body, and it is essential for skeletal development and for bone mineralization. A number of studies have reported significant benefits from supplemental vitamin D in supporting bone health. Along with the classic role it plays in regulation of bone mineralization and serum calcium levels, vitamin D has been increasingly recognized to play important roles in the regulation of blood sugar within normal levels, and supporting normal muscle strength, the health of connective tissue, and the gastrointestinal, immune, circulatory, and respiratory systems.* NOTE: Please be advised that although this product is in a vegetarian capsule, the product itself is not considered vegetarian.

According to Taber’s Medical Dictionary, “hypoallergenic” is defined as: “Diminished potential for causing an allergic reaction”. We define hypoallergenic as “free of all common allergens,” specifically: wheat, corn, soy, gluten, yeast, dairy, and eggs. Many very sensitive individuals who react to supplements in general are able to tolerate NutriCology products.
Since our inception in 1979 we have been using only the purest, and whenever possible, the lowest allergy potential natural ingredients. While many of the nutrients in our formulas are synthesized from natural substances (plant sources), which as a whole may contain antigens, the synthesizing process removes the molecules of the desired nutrient from the original substance, and in the processing, a great percentage of the antigens and allergens are left behind. The final material then has extremely low allergy potential.
This is not to say that no one will react to any of our hypoallergenic formulas, as some extremely sensitive people may. However, the potential for an allergic reaction is low, and the feedback from many of our extremely allergic and sensitive customers is that NutriCology supplements are often the only products they are able to tolerate.
New Allergen Labeling Regulations
As a result of the Food Allergen Labeling and Consumer Protection Act of 2004, effective January 1, 2006, the FDA requires manufacturers to identify the presence of eight major food allergens on all product labels.
The term “major food allergen” means any of the following:
• milk
• egg
• fish
• crustacean shellfish
• tree nuts
• peanuts
• wheat
• soybeans
• any ingredient derived from the above listed foods
It is important to understand that while an ingredient may have been derived from a common allergen, we are required by law to list that allergen on the label as a source of the ingredient, even if it does not contain any of the actual substance. For example, 100%-pure glucosamine sulfate does not contain any actual shellfish, but we are required to indicate the source material (shrimp, crab, lobster) on the label. Full Disclosure Labeling
Nutricology fully discloses all ingredients, both active and inactive on every product label,so you can make fully informed choices. Vegetarian Capsules
Nutricology is currently in the process of converting most of our existing products to vegetarian capsules, and all new products are being made with vegetarian capsules. |

NutriCology fully discloses all ingredients, both active and inactive, on every product label, so you can make fully informed choices for your patients.
Furthermore, the following is a list of inactive ingredients used in some of our products. These may be called fillers and/or excipients as defined by the Food Chemical Codex. These are nutrient compounds which are utilized for their physical properties to aid in the supplement production process. They are derived from edible sources and are generally free of common allergens. To determine which natural additives are included in a specific product, please refer to the supplement facts panel.Cellulose Powder is derived from fibrous plant material, is insoluble in water and is used as a filler. In addition to being used as a filler, cellulose powder is sold as an individual supplement as a pure insoluble fiber, and is extremely well tolerated. Silicon Dioxide, or silica, is one of the most common chemical compounds. Silica plays an important role in biological processes. Most rocks and minerals are made of silicon dioxide and other minerals. Silica is insoluble in water and is used for its drying properties. Stearic Acid is an 18 carbon, naturally occurring saturated fatty acid. It is a component of membrane structure and is utilized for its lubricating properties. Magnesium Stearate contains stearic acid and magnesium palmitate, which is magnesium salt of a 16 carbon saturated fatty acid, also common in membrane structure. It is also utilized for its lubricating properties. Dicalcium phosphate (calcium phosphate, dibasic) is a white, odorless, tasteless powder that is stable in air. It is practically insoluble in water, but is readily soluble in hydrochloric acid. L-leucine is an essential branched-chain amino acid, found in almost all animal and vegetable proteins. As an excipient in our formulas, pharmaceutical grade L-leucine is presented in minute amounts and is used as a lubricant. |
