Anthocyanins are the primary active forms found in fresh berries, combined and formed into an easy to use supplement, to complement your daily dynamic and overall well-being.

How Does Doctor’s Best Polyphenol-C Complex Work?

Improve and Maintain Good Health

Maintain your good health with potent antioxidants that help support a strong and healthy immune system. Filled with a concentrated blend of nature’s premium antioxidants that includes vitamin C and fruit polyphenols, this supplement supports the immune system, and supports a healthy heart. Also protects your cells and reduces the oxidative damage caused by free radicals.

Each gram of Polyphenol-C contains: 600mg of Non-GMO Vitamin-C and 100mg of Berry Polyphenols.

Helps fight free radicals and reduce oxidative stress

Polyphenols are the compounds primarily responsible for the red, purple and blue colorings of berries such as blueberries, blackberries, raspberries and strawberries. Their key role in plants is to protect them from insects, ultraviolet radiation, and possible infections. They are the most common phytochemicals in human diet and according to the chemical structures, they are classified as flavonoids (group that accounts for around 60% of polyphenol compounds and include anthocyanins, bioflavonoids, quercetin, catechins), phenolic acids (group that accounts for about 30% of all polyphenols), lignans, and stilbenes. Like berries, grapes contain many active compounds including polyphenols such as anthocyanins, procyanidins, and the stilbene derivative known as resveratrol.

Numerous studies have shown that bioactive components in berries and grapes possess antioxidant properties that are directly associated with the high amount of diverse groups of polyphenols present in these fruits. In recent years, a number of studies have examined the role of polyphenols in berries to show their potent antioxidant activities against oxidative stress-driven damages that can lead to cardiovascular weakness. Oxidative stress occurs in the body when there is a serious imbalance between the generation of free radicals and the antioxidant defense systems. Reactive oxygen (ROS) and nitrogen species are the major contributors to the development of oxidative stress. The antioxidant mechanism involves the scavenging of ROS that can cause oxidative damage to cellular macromolecules including DNA, RNA, proteins, and lipids. Antioxidants, such as polyphenol compounds, protect tissues and cell constituents against oxidative damage and therefore limit the risk of developing various health issues associated with oxidative stress.

Within the fruit group, strawberries are one of the most important sources of antioxidants and are considered as a functional fruit due to the presence of a diverse range of bioactive components and high levels of vitamin C, vitamin E, folates, and phenolic compounds, specifically, anthocyanins. Experimental studies have demonstrated that acute strawberry consumption increased plasma antioxidant capacity and reduced oxidative damages of plasma proteins. Henning et al. showed that a daily intake of 250 g of frozen strawberries increased antioxidant activity in the serum which in turn improved the body’s defense mechanism. Another study showed that 2 cups of strawberry drink per day for 4 weeks (each cup had 25 g of freeze-dried strawberry powder, containing about 1000 mg of phenolic compounds) can inhibit the lipid peroxidation process caused by ROS.

Blackberries are also a rich source of minerals, essential vitamins, calcium, and polyphenolic compounds such as anthocyanins. The property of blackberries has been known among Europeans since the 16th century. Studies on the scavenging capacity of different berries have shown that blackberries and strawberries have the highest antioxidant capacity.

Blueberries have a pharmacological effect on oxidative stress due to the presence of high amounts of polyphenols such as procyanidins and anthocyanins. In their prominent oxidative role, they serve as radical scavengers and could be useful in providing protection against oxidative stress and supporting cardiovascular health and overall body health.

Cranberries are a great source of vitamins and bioactive compounds such as phenolic compounds that are scientifically known for their powerful antioxidant activities. Among those phenolic compounds, there are anthocyanins (peonidin), flavonoids (quercetin), tannins (A-type proanthocyanidins), and phenolic acids.

The health benefits of grape consumption are thought to arise mainly from bioactivities of their polyphenols. A randomized, double-blind, placebo-controlled pilot study evaluated and confirmed the effect of whole grape extract on improved antioxidant status and lipid profile in healthy subjects.

Helps support endothelial function and cardiovascular health

Berry fruits are now considered a functional food since they offer health benefits beyond basic nutrition. In particular, there has been substantiated accumulating scientific evidence of their beneficial health benefits in supporting endothelial function and cardiovascular health. Berries have a wide range of nutrients and bioactive compounds that have extensively been reviewed for their protective effects against cardiovascular issues.

Promotes healthy cognitive function

Based on extensive literature on polyphenols and cognitive function, there is strong evidence that polyphenols may positively impact brain function especially during aging. Dietary intervention studies in animals and humans have shown that polyphenols contained in grapes and blueberries, may support memory and learning functions.

Supports healthy immune function

Vitamin C is (also known as ascorbic acid) a potent water-soluble antioxidant that contributes to immune defense by supporting various cellular functions of the complex immune system. It gives the immune system a boost through its increase in T-lymphocyte activity, phagocyte function, leukocyte mobility, and possible antibody production. Its effects on the immune system may also be potentially explained through protection against oxidative stress generated during infections. Vitamin C is not produced endogenously in humans and is therefore an essential nutrient component. It can be consumed through dietary sources like fresh fruits and vegetables, especially citrus and berry fruits, or through dietary supplements.

The Food and Nutrition Board has provided intake recommendations for vitamin C such as the recommended dietary allowance (RDAs: Average daily level of intake sufficient to meet the nutrient requirements of nearly all healthy individuals). For vitamin C, levels are based on its known physiological and antioxidant functions in white blood cells and are much higher than the amount required for protection from deficiency (RDAs for adults are 75 mg for women and 90 mg for men). The role of vitamin C in supporting immune function has been validated in various studies that were conducted to assess the effect of vitamin C in reducing cold duration.

Doctor’s Best Polyphenol-C Complex Benefits

Polyphenols have been linked to various health benefits.

Doctor’s Best Polyphenol-C Complex may lower blood sugar levels

Polyphenols may help lower your blood sugar levels, contributing to a lower risk of type 2 diabetes.

That’s partly because polyphenols may prevent the breakdown of starch into simple sugars, lowering the likelihood of blood sugar spikes after meals.

These compounds may also help stimulate the secretion of insulin, a hormone that’s required to shuttle sugar from your bloodstream into your cells and keep your blood sugar levels stable.

Various studies further link polyphenol-rich diets to lower fasting blood sugar levels, higher glucose tolerance, and increased insulin sensitivity — all important factors in lowering your risk of type 2 diabetes.

In one study, people eating the highest amounts of polyphenol-rich foods had up to a 57% lower risk of developing type 2 diabetes over 2–4 years, compared with those eating the lowest amounts.

Among polyphenols, research suggests that anthocyanins may offer the most potent antidiabetic effect. They’re typically found in red, purple, and blue foods, such as berries, currants, and grapes.

Doctor’s Best Polyphenol-C Complex may lower your risk of heart disease

Adding Doctor’s Best Polyphenol-C Complex to your diet may improve heart health.

Experts believe that this is largely due to the antioxidant properties of polyphenols, which help reduce chronic inflammation, a risk factor for heart disease.

Two recent reviews link polyphenol supplements to lower blood pressure and LDL (bad) cholesterol levels, as well as higher HDL (good) cholesterol.

Another review found a 45% lower risk of death from heart disease in those with higher enterolactone levels, which are a marker of lignan intake. Lignans are a type of polyphenol typically found in flax seeds and whole grains .

Doctor’s Best Polyphenol-C Complex may prevent blood clots

Doctor’s Best Polyphenol-C Complex may reduce your risk of developing a blood clot.

Blood clots are formed when platelets circulating in your bloodstream begin to clump together. This process is known as platelet aggregation and is useful in preventing excess bleeding.

However, excess platelet aggregation can cause blood clots, which can have negative health effects, including deep vein thrombosis, stroke, and pulmonary embolism.

According to test-tube and animal studies, polyphenols may help reduce the platelet aggregation process, thereby preventing the formation of blood clots.

Doctor’s Best Polyphenol-C Complex may protect against cancer

Research consistently links diets rich in plant foods to a lower risk of cancer, and many experts believe that polyphenols are partly responsible for this.

Polyphenols have strong antioxidant and anti-inflammatory effects, both of which can be beneficial for cancer prevention.

A recent review of test-tube studies suggests that polyphenols may block the growth and development of various cancer cells.

In humans, some studies link high blood markers of polyphenol intake to a lower risk of breast and prostate cancers, while others find no effects. Therefore, more studies are needed before strong conclusions can be made.

Doctor’s Best Polyphenol-C Complex may promote healthy digestion

Doctor’s Best Polyphenol-C Complex may benefit digestion by promoting the growth of beneficial gut bacteria while fending off harmful ones.

For instance, evidence suggests that polyphenol-rich tea extracts can promote the growth of beneficial bifidobacteria.

Similarly, green tea polyphenols may help fight off harmful bacteria, including C. difficile, E. Coli, and Salmonella,as well as improve symptoms of peptic ulcer disease (PUD) and inflammatory bowel disease (IBD).

Furthermore, emerging evidence indicates that polyphenols may help probiotics thrive and survive. These are beneficial bacteria that occur in certain fermented foods and can be taken in supplement form. However, more research is needed.

Doctor’s Best Polyphenol-C Complex may promote brain function

Doctor’s Best Polyphenol-C Complex may boost your focus and memory.

One study reports that drinking grape juice, which is naturally rich in polyphenols, helped significantly boost memory in older adults with mild mental impairment in as little as 12 weeks.

Others suggest that cocoa flavanols may improve blood flow to the brain and have linked these polyphenols to improved working memory and attention).

Similarly, the polyphenol-rich plant extract Ginkgo biloba appears to boost memory, learning, and concentration. It has also been linked to improved brain activity and short-term memory in those with dementia.

Doctor’s Best Polyphenol-C Complex Precautions and Side Effects

Animal studies show that high-dose polyphenol supplements may cause kidney damage, tumors, and an imbalance in thyroid hormone levels. In humans, they may result in an increased risk of stroke and premature death.

Some polyphenol-rich supplements can interact with nutrient absorption or interact with medications. For instance, they may reduce your body’s ability to absorb iron, thiamine, or folate.

If you have a diagnosed nutrient deficiency or are taking medications, it may be best to speak to your healthcare provider about polyphenol supplements before taking them.
