Mega Antioxidant

As a well-rounded multivitamin supplement, Mega Antioxidant contains a broad range of vitamins and antioxidants that work together to help each of the body’s cells function properly. The formula includes all eight B vitamins, several of which are involved in energy metabolism, helping to convert the carbohydrates, fats, and proteins we eat into fuel for our cells.

The micro-nutrients in Mega Antioxidant benefit nearly all the body systems, including the cardiovascular system, immune system, skeletal system, as well as brain and nerve function. Many of the key components have multiple benefits:


Vitamins C and E, along with beta carotene (which naturally converts into vitamin A only as needed, providing the benefits of vitamin A without the risk of toxicity), are each powerful antioxidants that also reinforce the activity of the others.

Flavonoids and phenolic compounds, which are abundant in fruits and vegetables, not only provide important protection against oxidative stress, they also complement and extend the activities of other antioxidants as well. A unique bioflavonoid complex—including quercetin, rutin, hesperidin, green tea, bilberry, pomegranate, and cinnamon—plus turmeric all work to inhibit the activity of free radicals.

Certain polyphenolic antioxidants found in olives are not present in other common dietary sources. They are structurally distinct from the bioflavonoids and other antioxidants found in fruits and vegetables. These antioxidants are found in USANA’s patented Olivol® olive-fruit extract.


Vitamin E and mixed tocopherols play a critical role in protecting LDL and cell membranes from oxidation, keeping arteries healthy. Vitamin C is also helpful in maintaining healthy veins and arteries by supporting healthy tissue growth and strengthening collagen.

The B vitamins, especially riboflavin, folate, and vitamins B6 and B12, are fundamental to the maintenance of healthy levels of the amino acid homocysteine, provided they are healthy to begin with. Homocysteine levels have been linked to heart health.

Vitamin B12 is also necessary for the health of red blood cells and DNA. Those who do not take a supplement containing vitamin B12 are twice as likely to be vitamin B12 deficient as supplement users, regardless of age group.

Coenzyme Q10 plays a key role in producing cellular energy, demand for which is especially high in the heart, making this an important nutrient for cardiovascular health. In addition, cellular-energy production requires a full spectrum of B vitamin activities.

USANA’s patented Olivol® helps protect low-density lipoproteins (LDL) from oxidation.


Mixed carotenoids, including beta carotene, lutein, and other antioxidants, helps maintain good vision. Lutein selectively accumulates in tissues in the eye to help protect against damaging UV rays.

Vitamin C is especially important for the retina, where concentration of this essential nutrient is significantly higher than in the blood.


By helping to maintain the integrity of all cell membranes, along with the digestive system and lungs, beta carotene is important for a healthy immune system.

Vitamins B6, B12, and folate are critical for producing immune cells.

Vitamin E, vitamin D, as well as vitamin C are well known for their immune-cell supporting properties.


Vitamin D helps in the development and maintenance of mineral-rich bones and teeth. Healthy levels of this important nutrient are a key part of minimizing age-related bone loss. It also supports muscle strength.


Vitamin C helps the body conserve glutathione, which is produced in the liver. Intracellular glutathione acts as a primary detoxification element.

N-acetyl l-cysteine can also help boost glutathione.

Choline and inositol help metabolize fats in the liver.


B vitamins support healthy brain and nerve function. Folate is especially important for women who may have children. Women who consume healthful diets with adequate folate throughout their childbearing years may reduce their risk of having a child with a birth defect of the brain or spinal cord.

Choline supports transmission of nerve impulses from the brain throughout the central nervous system, which provides memory support.


Antioxidants, such as vitamin E, help defend your cells against the oxidative stress caused by sunlight, pollution, and stress, which can all prematurely age the skin.

Lycopene, lutein, and beta carotene play a role in supporting the skin.

Inositol, biotin, and pantothenic acid are fundamental to the growth of healthy skin, hair, and nails.

Vitamin C is essential for synthesizing collagen, proteins that provide elasticity to our connective tissues (also important for maintenance of muscle, joint, and tendon function).
