USANA® Proflavanol®C 100 | Proflavanol C200: Two Powerful Antioxidants for One-of-a-Kind Health Support
Health trends may come and go. But the original “superfruit” still stands the test of time. Grapes have long been a source of health-protecting bioflavonoids—a powerful, beneficial type of plant compound. The seeds inside contain concentrated antioxidants that work to protect your health in many different ways. And when combined with vitamin C, the biological benefits of grape seed are enhanced for even better effectiveness.*
Get a boost of bioflavonoid power with USANA® Proflavanol® C. This one-of-a-kind supplement is made with USANA Nutritional Hybrid Technology. So, you get a combination of two potent antioxidants in one, two-layer tablet. Together, these nutrients will help you maintain good health in a number of ways:
- Neutralizes free radicals that, over time, could cause excessive oxidative stress that damages cells*
- Supports cardiovascular and circulatory health by helping to retain healthy, normal blood pressure and cholesterol levels, provided they are already in the normal range*
- Helps maintain strong veins, blood vessels, and capillaries*
- Supports balanced immune function*
- Helps maintain joint, muscle, and skin health*
Proflavanol C100 delivers 100 mg of the highest quality grape-seed extract and 300 mg of USANA’s unique Poly® C vitamin C blend in one, two-layer tablet. Or, choose Proflavanol C200 to get twice the amount of grape-seed extract in one tablet.
When you add Proflavanol C to your daily routine, you won’t just feel good about the many health benefits. A tasty grape-flavored coating on each Proflavanol C tablet makes taking your supplements even more satisfying.*
Get Unbeatable Cardiovascular Support with Proflavanol C
If helping your cardiovascular system stay healthy is important to you, Proflavanol C should be at the heart of your supplement regimen. Most people don’t meet the standards for a healthy heart set by American Heart Association.*
Your cardiovascular system, also called your circulatory system, consists of your heart, lungs, and blood vessels—which include arteries, capillaries, and veins. This system is responsible for moving oxygen, nutrients, waste products, and other compounds through your body in your blood. Your heart is the muscular pump. The vessels are the “superhighway” through which your blood circulates.
Keeping this system flowing smoothly means maintaining the health of your blood vessels. Proflavanol C helps support vascular function. This will aid your efforts to maintain normal, healthy blood pressure levels—provided they are healthy to begin with.*
The cardiovascular advantages of Proflavanol C come from the unique combination of antioxidants.*
Proanthocyanidins from grapes are also present in red wine. They are believed to be one of the factors that contribute to the “French Paradox”—the fact that the French maintain good heart health despite a diet high in saturated fat. And vitamin C has been associated with markers of heart health, including supporting healthy blood flow.*
The combination of grape-seed extract and vitamin C in Proflavanol C helps maintain your cardiovascular health in a couple key ways.*
First, these nutrients help defend against low-density lipoprotein oxidation (bad cholesterol). This means Proflavanol C helps maintain lipids and proteins in cholesterol from changing into unhealthy end products.*
Proflavanol C also supports or maintains healthy circulation and blood flow by protecting endothelial cells from excessive oxidative stress. These cells line the interior surface of your blood vessels and arteries. One of their many functions is making nitric oxide. This substance signals for vasodilation (a fancy word for relaxing—or dilating—your blood vessels). That allows your blood to flow through your vascular system more easily.*
Nitric oxide function can be inhibited by excessive free radical damage. By protecting endothelial cells’ ability to produce nitric oxide, Proflavanol C supports healthy circulation.*
It even supports circulation in your tiniest blood vessels—including the peripheral arteries in your fingertips. A study conducted at Boston University School of Medicine found that combining grape-seed extract with vitamin C helped retain healthy micro-vascular function. Interestingly, this only occurred when epicatechin, another of the bioflavonoids in grape-seed extract, was also present in the blood.*
The Collagen Connection: Heart, Skin, and More
Another key part of cardiovascular health is supporting the strength of your heart muscle and blood vessels. Both require collagen for structure and support. This means both require adequate amounts of vitamin C. (You also need other nutrients, like calcium and coenzyme Q10.) Because human bodies are incapable of manufacturing vitamin C, you must rely on your diet to satisfy daily requirements.*
Your body uses vitamin C to make many different types of collagen. These structural proteins are abundant throughout your body. Because they are needed to form healthy tissue.*
Here are a few of the most common types of collagen and where you’ll find them:
Type I: Fibers found in connective tissues of bone, teeth, tendons, and ligaments.
Type II: Found in cartilage.
Type III: Makes up connective tissues that give shape and strength to organs, such as the heart, liver, kidneys, etc.
Type IV: Found in the layers of cells in the blood vessels, muscles, and eye.
By supporting collagen production, Proflavanol C can help maintain a hardy heart, plus strong blood vessels, veins, and capillaries. But, as you can see, collagen is truly essential for an overall healthy body.*
Your appearance, too, can be affected by collagen. It‘s integral to skin’s elasticity and firmness. But collagen tends to start breaking down as you get older. So, taking vitamin C can help support production of this important protein.*
Your skin can also maintain health from within, with the help of the antioxidant activity provided by Proflavanol C. Defending against the oxidative effects of sun exposure may help protect against visible signs of aging. Of course, make sure to use smart sun safety measures to preserve your skin’s youthful appearance, too.*
Help Your Body Produce Immune Cells with Proflavanol C
Your immune system is an incredibly complex protective mechanism designed to shield your body. And when your shield is weakened, your body is at risk. Exposure to potentially harmful microorganisms, along with stress or even intense exercise, can temporarily tax your immune system.
Grape-seed extract works with vitamin C to support two vital aspects of your natural immunity:
- Grape-seed bioflavonoids can help support your cells’ ability to communicate with each other for healthy immune responses.*
- Vitamin C plays a role in the normal production and function of white blood cells and antibodies. You need to keep those abundant if you want a strong immune system.*
- Poly C
- Grape-Seed Extract
