Vitamin A

Vitamin A is a group of unsaturated nutritional organic compounds that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids (most notably beta-carotene). Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision. Vitamin A is needed by the retina of the eye in the form of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision. Vitamin A also functions in a very different role as retinoic acid (an irreversibly oxidized form of retinol), which is an important hormone-like growth factor for epithelial and other cells. In foods of animal origin, the major form of vitamin A is an ester, primarily retinyl palmitate, which is…

Vitamin B1

Vitamin B1 is also called  Thiamine.   Vitamin B1 is one of the eight B vitamins. It has acquired several names since discovery including Aneurin and, as of the year 2000, thiamin (thiamine). Because thiamin can only be stored in the body for a short time before it is readily excreted, a regular dietary intake of thiamin is necessary to maintain proper blood levels. Moderate amounts of thiamin can be found in most foods, yet the food sources richest in thiamin include whole-grains, brown rice, pork, poultry, soybeans, nuts, dried beans, peas, and fortified or enriched grain products such as cereals. The recommended daily intake (RDI) for adults over age eighteen is 1.2 mg/day for men and 1.1 mg/day for women. For children, adequate intake levels are lower, with RDI levels…

Vitamin B2

Vitamin B2 (also known as Riboflavin) is all about energy. And it does its job as a coenzyme that catalyzes redox—short for reduction/oxidation—reactions. They move electrons between different molecules during a chemical reaction. All redox reactions require a molecule with extra electrons. You may be familiar with the redox reactions that happen between antioxidants and free radicals. The same mechanics of electron transfer are at work here, for a different purpose—energy. Riboflavin (also known as vitamin B2) is one of the B vitamins, which are all water soluble. Riboflavin is naturally present in some foods, added to some food products, and available as a dietary supplement. This vitamin is an essential component of two major coenzymes, flavin mononucleotide (FMN; also known as riboflavin-5’-phosphate) and flavin adenine dinucleotide (FAD). These coenzymes…

Vitamin B3

Niacin, also known as nicotinic acid, is an organic compound and a form of vitamin B3, an essential human nutrient. It has the formula C ₆H ₅NO ₂ and belongs to the group of the pyridinecarboxylic acid. Wikipedia IUPAC ID: pyridine-3-carboxylic acid Formula: C6H5NO2 Molar mass: 123.11 g/mol Melting point: 237 °C Density: 1.47 g/cm³ Soluble in: Water Clinical symptoms of a vitamin B3 niacin deficiency are usually categorized as the “3 D's”: dermatitis (skin rashes), diarrhea, or dementia. ... When a vitamin B3 niacin deficiency is seen, the following are signs and symptoms: Pellagra- characterized by skin inflammation, hallucinations, digestive distress. VITAMIN B3 (NIACIN) What is it? A water-soluble B vitamin involved in energy production from dietary intake. What does it do for me? Supports the transformation of food…

Vitamin C

Vita Antioxidant is rich in vitamin C. USANA uses a unique Poly C® vitamin C blend, which provides higher levels of vitamin C in plasma than ascorbic acid alone.* Vitamin C is essential for making collagen—proteins that provide elasticity to your connective tissues. That’s why vitamin C is helpful in maintaining healthy veins and arteries, muscles, cartilage, tendons, bones, teeth, and skin. It also supports fat and protein metabolism, as well as the healthy production of immune cells.* Note: You will notice 300 mg of vitamin C on the Core Minerals label. This is because the magnesium and calcium blends are made partly from the ascorbate forms of the nutrients. Ascorbate is a source of vitamin C. Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin that is…

Vitamin D

Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. Vitamin D obtained from sun exposure, food, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D [25(OH)D], also known as calcidiol. The second occurs primarily in the kidney and forms the physiologically active 1,25-dihydroxyvitamin D [1,25(OH)2D], also known as calcitriol. Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone and to prevent hypocalcemic tetany. It is also needed for…

Vitamin E

Vitamin E is found naturally in some foods, added to others, and available as a dietary supplement. “Vitamin E” is the collective name for a group of fat-soluble compounds with distinctive antioxidant activities. Naturally occurring vitamin E exists in eight chemical forms (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) that have varying levels of biological activity. Alpha- (or α-) tocopherol is the only form that is recognized to meet human requirements. Serum concentrations of vitamin E (alpha-tocopherol) depend on the liver, which takes up the nutrient after the various forms are absorbed from the small intestine. The liver preferentially resecretes only alpha-tocopherol via the hepatic alpha-tocopherol transfer protein; the liver metabolizes and excretes the other vitamin E forms. As a result, blood and cellular concentrations of…
