Beta Carotene
Beta carotene, as the best known member of the carotenoid family, provides a dual nutritional function. In addition to its role as an excellent antioxidant, the body is able to convert beta carotene into vitamin A.
Betaine
Betaine (also known as trimethylglycine or TMG) was first isolated from sugar beets. Betaine is closely related to choline, folic acid, and vitamin B12, and it plays an important role in normal homocysteine metabolism.
Bioflavonoid Complex
Bioflavonoids are a diverse class of compounds with antioxidant activity. They are found naturally in the leaves, bark, roots, flowers, and seeds of plants.
Biotin
As a member of the B vitamin family, biotin plays an essential role in four human enzyme systems. Additionally, secondary roles for biotin are thought to exist in cell growth and DNA synthesis.
Boron
Boron is a non-metallic mineral present in the human body in trace amounts. Dietary boron influences the activity of many metabolic enzymes, certain hormones, and the metabolism of several micronutrients, including calcium, magnesium, and vitamin D.
Bromelain
Bromelain is a family of enzymes obtained from the stem of pineapple plants. Studies conducted in vitro and in vivo have demonstrated anti-tumor, anti-inflammatory, anti-thrombotic and fibrinolytic activities.

Folate
product.cms.ingredient.folate.desc
Folic Acid
Folic acid, a water-soluble B vitamin, helps form building blocks of DNA (the body's genetic blueprint). As a result, rapidly growing tissues (such as those of a fetus) and rapidly regenerating cells (like red blood cells and immune cells) have an especially high need for folic acid.
Gingko Biloba
Extracts from Ginkgo biloba leaves have played a crucial role in Chinese herbal medicine for many centuries. Recent studies have shown that Ginkgo extract contains antioxidant and anti-inflammatory properties, reduces platelet aggregation, demonstrates free radical scavenging activity, increases blood flow and circulation, and improves the transmission of certain nerve signals.
Glucosamine Sulfate
Glucosamine is a basic building block of animal and human cartilage (the tissue that lines, cushions, and lubricates skeletal joints). Because of its important role in regulating cartilage formation, glucosamine has been used clinically in the treatment of osteoarthritis.
Grape Seed Extract
The cardioprotective effect of red wine has been attributed to a group of bioflavonoid compounds called proanthocyanidins. Proanthocyanidins are concentrated in the seeds of grapes. These compounds act as effective antioxidants, as well as supporting capillary strength.
Green Tea Extract
Green tea extract is rich in a class of bioflavonoid compounds called catechins, which are considered to be very powerful antioxidants. In vitro studies have also shown green tea extract to have strong antimutagenic potential.
Iodine
Iodine is a key component of the thyroxine hormone produced by the thyroid gland. Thyroxine is important in general metabolism regulation and normal fetal development.
Iron

Lutein
Lutein belongs to a class of antioxidant compounds called carotenoids. Lutein is the primary carotenoid found in the central area of the retina (known as the macula). Consequently, lutein appears to be associated with protection from age-related macular degeneration, a leading cause of blindness in older adults.
Lycopene
Lycopene - a member of the carotenoid family of antioxidants - is responsible for the deep red color of tomatoes, strawberries, and watermelon. Recent studies have demonstrated a strong correlation between intake of lycopene-rich foods and a reduced risk of heart disease and cancer.
Magnesium
Magnesium is an essential mineral for many fundamental processes in the body. It normally exists in the body as a charged particle (or ion) and is primarily stored in bones. Magnesium plays an integral role in hundreds of enzymatic functions and is important for nerve, muscle, and bone health.
Manganese
Manganese performs a number of essential roles in cellular function and human metabolism. In particular, it is an important constituent of an enzyme called manganese superoxide dismutase (MnSOD) which helps protect tissues against oxidative damage.
Milk Thistle Extract
Milk Thistle Extract is one of the most powerful antioxidants currently known, and it may help increase both the amount and the activity of several antioxidant enzyme systems involved in detoxification processes (including superoxide dismutase (SOD) and the glutathione /glutathione peroxidase system).
Molybdenum
Molybdenum was first shown to be an essential mineral in 1953. Molybdenum functions primarily as an oxidizing agent, which gives it a very important role in the transport of electrons in oxidation-reduction reactions.
Niacin
Niacin and its derivative niacinamide are two forms of a water-soluble vitamin referred to as vitamin B3. Both compounds are precursors for the active forms of important enzyme cofactors (coenzymes) that assist in catalyzing oxidation-reduction reactions in human cells.
Olivol
Olivol is USANA's patented extract containing potent antioxidant polyphenols derived exclusively from the fruit of olives. USANA patented a process to recover olive phenols from the by-products of olive oil production to formulate a proprietary antioxidant exclusive to USANA.
Omega-3 Fatty Acid
Our bodies can produce most fatty acids from the food we eat. However, there are two fatty acids (called "essential fatty acids") we cannot produce, meaning we must obtain them from dietary sources. Omega-3 fatty acids support healthy blood pressure, cholesterol and triglyceride levels (providing they are normal to begin with), healthy kidney function, inflammatory response, and healthy immune function.
Pantothenic Acid
Pantothenic acid (or vitamin B5) is a water-soluble nutrient widely synthesized by plants and many bacteria, and essential in the diets of all vertebrate animals, including man. In humans, pantothenic acid is essential for the production of energy from carbohydrates, fat, and protein.
Phosphorus
product.cms.ingredient.phosphorus.desc
Riboflavin
Riboflavin (vitamin B2) functions primarily as part of two coenzymes. These coenzymes participate in oxidation-reduction reactions needed for the production of energy from glucose, amino acids, and fatty acids.
Selenium
Selenium is an essential trace element that functions as part of the enzyme glutathione peroxidase, a vital antioxidant enzyme system that protects cell membranes.
Silicon
Silicon is the 2nd most abundant element in the earth's crust (after oxygen) and an essential element for both animals and plants. Its most important function in humans involves healthy growth and development of bone, cartilage, and connective tissue.
Soy Isoflavones
The isoflavones in soy (primarily genistein and daidzein) have been well-researched for their antioxidant and estrogenic properties. More recent research has focused on the role of soy in supporting healthy bone structure, cardiovascular health, and menopausal support.
Thiamin
Thiamin (or vitamin B1) is a water-soluble vitamin required for normal energy metabolism and cell division. In particular, thiamin plays a central role in the production of energy from sugars, starch, and other fuels.
Turmeric Extract
Turmeric is a member of the ginger family. The powdered root has a long history of use as a spice (especially in India and the Middle East), and it is also used as a natural food colorant. Recent clinical studies have investigated turmeric for potential antioxidant and anti-inflammatory properties.

Vitamin A
product.cms.ingredient.vitamin.a.desc
Vitamin B12
Vitamin B12, the most complex of all the vitamins, is also one of the few essential substances in the body that contains the mineral cobalt. Along with folic acid and vitamin B6, vitamin B12 plays a key role in the maintenance of homocysteine levels, an independent risk factor of cardiovascular disease.
Vitamin B6
Vitamin B6 (or pyridoxine) is an essential water-soluble vitamin. Like all true vitamins, B6 functions as a coenzyme, meaning that it works in tandem with one or more enzymes to catalyze metabolic reactions in cells. In fact, vitamin B6 serves as a cofactor for over 100 enzymes in the human body.
Vitamin C
Vitamin C, also known as ascorbic acid, plays two important roles in the body. First, it is a cofactor for eight enzyme systems involved in various functions, including collagen synthesis, ATP synthesis in mitochondria, and hormone biosynthesis. Second, vitamin C is a powerful water-soluble antioxidant.
Vitamin D
Vitamin D is a fat-soluble nutrient essential for bone growth and general health. It is acquired through diet and exposure to sunlight. Vitamin D is essential for normal bone development, particularly in children. Without it, bones do not calcify properly, leading to the condition known as "rickets."
Vitamin E
Vitamin E, unlike other vitamins, is not a cofactor in the function of specific enzyme systems. Rather, it is a potent antioxidant that protects cells and tissues from oxidative damage induced by free radicals.
Vitamin K
Vitamin K is an essential nutrient required for the synthesis of multiple proteins involved in the regulation of blood clotting. In addition, vitamin K-dependent proteins appear to be involved in bone crystal formation and bone remodeling.
Zinc
Zinc is an essential mineral and a cofactor for more than 300 enzymes needed for cell function in the eyes, kidneys, muscles, skin, and bones. Zinc also serves as a necessary structural component of DNA-binding proteins, as well as helping release vitamin A from its storage place in the liver.
