Our Experts Say

Vitamin C is essential for the production of collagen, which makes it an important facet of skin, bone, and joint health, and it also contributes to proper immune function. We call this unique, proprietary formula for antioxidant protection Ultimate Bio-C because it provides bioavailable vitamin C and citrus bioflavonoids for ultimate vitality support. So you can stay healthy and well through every season.

50% Citrus Bioflavonoids
Bioflavonoids are a group of plant-based compounds known to function as cell-signaling agents, meaning they can interact with cells in the body and help to regulate various physiological processes. Bioflavonoids support healthy metabolism by modulating the activity of certain enzymes and proteins that are involved in the metabolism of lipids, carbohydrates, and other nutrients.
Antioxidant Power of Vitamin C
Citrus bioflavonoids and vitamin C are both powerful antioxidants that can help to protect the body's cells from damage caused by free radicals. This can help to reduce the risk of chronic diseases such as cancer and heart disease. Recent studies have shown that citrus bioflavonoids can also support healthy, supple skin.
Lowers LDL
A high-quality Vitamin C supplement like Ultimate Bio-C may play a beneficial role in cardiovascular health. Studies have found that consuming adequate amounts of Vitamin C can help to lower levels of LDL cholesterol, commonly known as "bad" cholesterol, while increasing levels of HDL cholesterol, often referred to as "good" cholesterol. This balance can help to reduce the risk of stroke or heart attack.

What's in the Bottle

Vitamin C
Vitamin C plays a key role in the growth, development, and repair of all body tissues, including skin and blood vessels. It also acts as an antioxidant that protects your cells from free radical damage and supports immune system function by promoting white blood cell production. Vitamin C can even help reduce the risk of developing certain types of cancers due to its anti-inflammatory property.
Citrus Bioflavonoid Complex
Citrus bioflavonoids are compounds found in citrus fruits such as oranges, lemons, and limes. They are known for their antioxidant properties, which help to protect the skin from damage caused by free radicals. Citrus bioflavonoids may also improve the appearance of fine lines and wrinkles, as well as promote a brighter, more even skin tone.
