How important is vitamin D for the immune system?
Space limits listing all of the roles that vitamin D plays in the body, but itās fair to say that since nearly every bodily cell and tissue has vitamin D receptors, they all require vitamin D to function properly [1, 2]. Regarding the immune system, the vitamin D in EnDuro D is very much a āfront line defenseā nutrient.
A portion of the conclusion from one piece of vitamin D/immune system research states: āVitamin D has important functions beyond those of calcium and bone homeostasis which include modulation of the innate and adaptive immune responses. Vitamin D deficiency is prevalent in autoimmune disease. Cells of the immune system are capable of synthesizing and responding to vitamin D.ā [3]
Commenting on other vitamin D/immune system research [4], Dr. Richard Mellanby writes: "Low vitamin D status has long been implicated as a significant risk factor for the development of several autoimmune diseases. Our study reveals one way in which vitamin D metabolites can dramatically influence the immune system."
Lastly, highly regarded vitamin D expert, Dr. Richard F Holick, states that vitamin D āis capable of regulating a wide variety of genes that have important functions in regulating cell growth, modulating immune function and cardiovascular health. Epidemiologic evidence and prospective studies have linked vitamin D deficiency with increased risk of many chronic diseases including autoimmune diseases, cardiovascular disease, deadly cancers, type II diabetes and infectious diseases.ā [2]

What makes Endurance C different that other vitamin C products?
There are many reasons!
Endurance C contains two forms of vitamin C:
- Calcium Ascorbate, known as "neutral C," "buffered C," or "non-acidic C," with a pH of 7.0-7.4. (Unlike "regular" Vitamin C, ascorbic acid, which is highly acidic and may cause gastric distress). While the compound is mostly vitamin C (90%), it also contains a beneficial 92 mg of calcium (10%).
- Ascorbyl Palmitate is a highly bioavailable, non-acidic, fat-soluble form of Vitamin C that can reach specific tissue areas that standard vitamin C cannot. Thus, ascorbyl palmitate can neutralize specific free radicals that water-soluble vitamin C can't. It also protects against the oxidation of lipids, a broad group of macronutrients that are heavily involved in many essential bodily functions (e.g., hormone regulation, nerve impulse transmission, fat-soluble nutrient transport, and more).
But there's MUCH more than just vitamin C in Endurance C. We've added the following nutrients/compounds, working synergistically to provide a tremendous range of benefits that you don't get in the typical vitamin C supplement:
- Citrus Bioflavonoids. While not strictly vitamins, bioflavonoids have impressive vitamin-like properties, which is why this group of compounds is known as Vitamin P. Citrus fruits contain several bioflavonoids, such as diosmin and naringin tangeretin, diosmetin, marirutin, neohesperidin, nobiletin, and others. These bioflavonoids work synergistically with vitamin C to support the immune system with antioxidant properties. Citrus bioflavonoids also enhance circulation, reduce aches and soreness, and help support joint health.
- Hesperidin 95% HPLC is a major bioflavonoid found primarily in lemons, oranges, and tangerines. Hesperidin possesses potent antioxidant properties for supporting vital immune system function, but it can also help blood vessels function better, thus promoting optimal circulatory and cardiovascular health. Additionally, hesperidin helps reduce aches and soreness, supports insulin sensitivity, and may also help protect cognitive health.
- Quercetin is a highly versatile bioflavonoid obtained from various sources, including citrus fruits, apples, onions, and more. Quercetin has extraordinary antioxidant properties, making it a top nutrient for immune system health. Quercetin possesses properties that strongly reduce aches and soreness, as well as helping to alleviate discomforts associated with allergies. Additionally, quercetin is believed to be highly beneficial for brain and cardiovascular health while also normalizing blood pressure and blood sugarālastly, quercetin and vitamin C work in tandem in optimizing each other's absorption.
- Rose Hips (Rosa canina). A natural source of Vitamin C, rose hips are a rich source of antioxidant carotenoids and polyphenols. One of these is tiliroside, which has antioxidant properties assisting non-stimulant fat loss.
Why are nutrients that used to be measured in International Units (IU) now measured in milligrams or micrograms?
Q: Why are nutrients that used to be measured in International Units (IU) now measured in milligrams or micrograms, and what is the difference between these two measurements?
A: International Units (IU) was historically used to measure vitamin A, beta-carotene, vitamin D, and vitamin E. However, the United States Food and Drug Administration (FDA) required that supplement facts labels change IU to metric units, which is why you now see milligrams (mg) or micrograms (mcg).
Itās important to know that even though there is a new standard of measurement, the amounts of the nutrients have not changed in any of the affected Hammer Nutrition products.
Vitamin D ā 1 IU = 0.025 mcg
Example: 1 softgel of EnDuro D contains 2,000 IU of vitamin D, now expressed as 50 mcg.
