    D-1,000 IU by Thorne Research

    Thorne Research D-1,000 - 90 Vegetarian Capsules

    It is essential to maintain healthy vitamin D levels throughout all stages of life, from fetal development to old age. Vitamin D helps protect a number of important functions in the body. The current recommended daily vitamin D intake of 400 IUs is based on the minimum allowance to protect against bone disease. However, an upward revision of the FDA's guideline is now under consideration in light of new research, especially pertaining to immune function. Cutting-edge research suggests serum vitamin D levels should be in the range of 32-80 ng/mL 25-hydroxyvitamin D (25(OH)D). Although direct sunlight exposure is a good source of vitamin D, many people do not get enough sun due to season change, latitude, or lifestyle. Therefore, vitamin D supplementation can be of great benefit in these cases.

    Vitamin D functions as a hormone that regulates calcium metabolism and supports cardiovascular health, bone, muscles, and immune function. Also, epidemiological studies show higher serum Vitamin D levels are associated with a healthier lifespan.

    A Vitamin From The Sun
    Humans make Vitamin D from exposure to ultraviolet radiation from the sun (or tanning beds). A cholesterol-like molecule, 7-dehydrocholesterol, is converted in the skin to a pre-vitamin D molecule, which is then converted to 25-hydroxy Vitamin D (25(OH)D) in the liver. This form of Vitamin D is converted when necessary to active 1,25-dihydroxy Vitamin D. Laboratory tests of serum 25(UH)D can detect when the body has a sufficient amount of Vitamin D.

    How Much is Recommended?
    The amount of vitamin D needed to achieve minimum vitamin D sufficiency (commonly defined as a 32-ng/mL 25(OH)D blood level) depends on many factors and can vary significantly from individual to individual. Thus, the requirement for vitamin D supplementation needs to be individualized. Thorne's D-1,000 supplies 1,000 IU of pure, vitamin D3 in each vegetarian capsule. This potency is ideal for maintaining optimum vitamin D levels in healthy individuals. Most Vitamin D experts recommend at least 1,000 IU of supplemental Vitamin D daily, and 10,000 IU or more might be necessary for some people. Other experts recommend weekly dosing of 25,000-50,000 IU Vitamin D3. Also, to acutely optimize the immune response, Dr. John Cannell, Executive Director of the non-profit Vitamin D Council, recommends up to 2,000 IU per kilogram body weight for 3-5 days.

    Thorne Takes Purity to Another Level
    Some vitamins, because of their potency, are usually given in very small amounts. Examples of such "micro-dose" vitamins include vitamin D, vitamin K, and vitamin B12. Most dietary supplement manufacturers purchase "micro-dose" vitamins from raw material suppliers as premixed dilutions, meaning the vitamins (in powder form) are mixed with other powdered substances that in turn make it easier for the manufacturer to handle and mix a larger quantity of raw material. Unfortunately, the powdered substances used in these premixed dilutions frequently contain potentially detrimental ingredients such as lactose and also the preservatives BHT, BHA, sodium benzoate, and sorbic acid.

    At Thorne Research, their promise is to give you the purest supplements humanly possible. Therefore, they do not purchase premixed dilutions of any "micro-dose" vitamins. Instead, Thorne purchases pure, undiluted vitamins and creates their own dilutions when it is necessary to do so, using pure, hypoallergenic powders, such as magnesium citrate or plant cellulose The resultant premixture is then added to the dietary supplement being made, ensuring the proper amount of each pure nutrient is contained in each capsule.

    • Thorne's Vitamin D is pure vitamin D – without hidden ingredients like lactose, BHT, BHA, sodium benzoate, and ascorbic acid
    • made without flowing agents that can inhibit bioavailability
    • supports cardiovascular, immune, and bone health

    Dr. Michael Lebowitz D.C. Recommends:
    We are all aware of how necessary vitamin D is for immune and endocrine support and bone density. Most of us don't spend enough time outdoors, or we live in climates with inadequate sunshine or use skin lotions that block UV absorption. D-1,000 is a great maintenance product, while D-10,000 is for restoring deficiencies of this essential nutrient.

    Thorne Research's Mission
    At Thorne Research, their mission is to enhance the health and well-being of people by providing superior dietary supplements that have the highest level of quality and purity – thereby creating the most respected and valued company in the dietary supplement industry.

    The Thorne Difference.
    For more than 25 years, Thorne has relentlessly pursued the highest possible quality and bioavailability in dietary supplements. At Thorne, they actually manufacture products that they sell – a key difference that allows Thorne to control every aspect of the manufacturing process and ensure that every Thorne product is in pure, completely hypoallergenic form, and without the common additives, flowing agents, and binders used throughout the industry.

    A few other companies have tried to do what Thorne does, and many others claim to have the same philosophy and quality, but nobody has been able to duplicate what Thorne's clients call "Thorne Quality." Thorne has changed the industry in many ways over the past two decades, and they continue to raise the bar and set new standards in product formulation, raw material purity, manufacturing, and quality control.

    Thorne's Commitment to Purity
    Practitioners have become accustomed to seeing the vague "We use only the purest ingredients" in the promotional materials of almost every dietary supplement company. Perhaps these companies truly believe that. Perhaps they don't know any better. Nevertheless, Thorne Research, for more than 25 years, has been the standard by which companies in the industry are judged for product purity. Practitioners rely on Thorne as the company they trust for their extremely allergic, chemically sensitive, and immune-compromised patients.

    Purity Takes Extra Effort
    For example, instead of purchasing prediluted vitamin D, as other companies do, Thorne performs its own dilution to avoid detrimental ingredients, such as the preservatives or lactose that are found in many commercially available dilutions. Why must vitamin D be diluted? Because in its pure form, it is too concentrated to safely blend into a vitamin product. Pure vitamin D is 40 MILLION International Units (IU) per gram. The RDA for adults is 600-800 IU per day. To ensure proper mixing, it must be made into a dilute powder that flows and does not lose potency. So, unlike companies that use prediluted vitamin D that contains unacceptable excipients and preservatives, at Thorne, pure pharmaceutical vitamin D is first blended with pure mixed tocopherol vitamin E, and the resultant stable vitamin D is then blended with hypoallergenic cellulose powder. The final powder is blended in a large tumble blender and subsequently analyzed. Not only is the final product stable; it is also hypoallergenic and can be mixed homogeneously and at a safe level with other powders. Just as with vitamin D, Thorne utilizes similar processes for other raw materials, such as vitamin K, leaving it to other companies to purchase commercially available raw materials filled with unacceptable ingredients and preservatives.

    Ingredients You Don't Want
    Magnesium Stearate: Good for speed-hungry encapsulating machines. Not necessarily good for you. Manufacturing encapsulated dietary supplements isn't easy. Pure powdered ingredients are difficult to mix because they are either extremely dry, sticky with botanical oils, or attract unwanted moisture. So most manufacturers add magnesium stearate and other agents such as lactose and dextrose to make the powder flow quickly and easily through their high-volume machines. Problem is, these additives may compromise the bioavailability of the nutrients in the supplement, and might cause allergenic problems. At Thorne, they take a different approach.

    Thorne will never utilize large fatty acid excipients in its manufacturing processes – ingredients such as magnesium stearate or stearic acid. These excipients are utilized as flowing agents to ensure that maximum productivity is obtained from capsuling and tableting machines. There are documented detrimental effects directly attributed to long chain fatty acids utilized as manufacturing flowing agents. Every qualified pharmaceutical compounder recognizes that large fatty acids, such as magnesium stearate, can interfere with product dissolution and influence absorption. Virtually all companies, because of the economic impact, ignore this data. As with most industries, the bottom line dictates the level of quality. The dietary supplement industry has one exception: Thorne Research, the company that does not compromise. Nevertheless, if a company cannot manufacture products without using detrimental excipients, they should not allude to being either "hypoallergenic" or "pure."

    The Bottom Line?
    Thorne is the only hypoallergenic dietary supplement manufacturer with the highest degree of purity that you – and your most severely allergic, chemically sensitive, and immune-compromised patients – can truly trust.

    Quality Ingredients: A Higher Standard
    At Thorne, they are committed to setting a higher standard of quality when it comes to ingredients. To produce their truly hypoallergenic encapsulated supplements, Thorne uses only the purest and finest ingredients available.

    Every manufacturer has two basic options when purchasing raw materials: purchase either truly pure raw materials, or purchase raw materials to which substances have been added to facilitate manufacturing. This fundamental dilemma translates to these very typical questions: "Do I purchase pure vitamin C or vitamin C with additives?" "Do I purchase pure B vitamins or coated B vitamins for taste masking?" "Do I purchase pure enzymes such as pancreatin, pepsin, and bromelain or enzymes diluted with lactose?"

    There are few commercial sources for vitamins B12, D, K, or biotin that are not diluted with substances such as lactose, cornstarch, and preservatives such as BHT. That's why Thorne developed methods that allow them to use pure, undiluted sources of these nutrients – and many others. It's just one more example that when it comes to quality, what everyone else accepts as an industry standard isn't good enough. While some companies say they are raising their standards....at Thorne they set them.
