Bioflavonoids (1) are plant pigments found naturally in some vegetables and fruits. The rind (outermost coat) of citrus fruits is particularly rich in bioflavonoids. The characteristic color of many fruits and vegetables is often due to the presence of bioflavonoids.

Bioflavonoids, also sometimes referred to as flavonoids, were traditionally known as Vitamin P.

Over 4000 of these polyphenolic compounds have been identified (2). Since bioflavonoids potentially offer a wide variety of benefits to the body, a lot of these compounds have been subjected to human-based clinical trials and have been approved by FDA for consumption.

The four major categories of bioflavonoids are proanthocyanidins, green tea polyphenols, citrus bioflavonoids, and quercetin.


This class of compound is naturally found in many plants and red wine.

PCOs, enhance the body’s immune response tremendously. It prevents free radical damage, acts as an anti-inflammatory agent, and shows antioxidant effects.

PCOs can also act as a treatment for strokes and heart diseases. Green Tea Polyphenols

This class is largely derived from the tea plant Camellia Sinensis.

It shows a lot of antioxidant effects in the body. The biggest benefit that green tea polyphenols offer is preventing cancers of the stomach, liver, lungs, and intestines.

Citrus Bioflavonoids:

This category includes major compounds like rutin and Quercetin. It is found naturally in a lot of citrus fruits.

As citrus fruits are also well-known for high vitamin C content, these bioflavonoids increase vitamin C uptake by the cells.

They also have anti-allergic and anti-inflammatory effects on the body.


Perhaps the most common active bioflavonoid that people use is Quercetin. Quercetin is a building block for other categories such as citrus bioflavonoids (2).

It is found in different fruits, vegetables, and a variety of grains.

It acts as a major anti-inflammatory agent by inhibiting the release of histamine. It supplements the benefits of vitamin C and acts as an antioxidant agent.

It also serves as a potential treatment fordiabetes-related issues, such as preventing retinopathy and diabetic cataracts.

It also observed that Quercetin shows anti-viral activity in the body against some fatal viruses such as herpes, polio, and respiratory syncytial virus.

It is also beneficial against rheumatoid arthritis, which is an autoimmune disorder. Quercetin is also known to prevent certain types of cancers in the body.

Bioflavonoids Benefits

Now that we have talked about all the categories of bioflavonoids, let’s dig into a few major benefits that this class of compounds offers.

Efficient blood circulation:

Evidence suggests bioflavonoids improve the cytoskeletal structure of our blood vessels by making them more flexible and strong.

Any vascular disorders which can impede the smooth blood flow to the organs can be potentially treated by the bioflavonoids.

Such vascular disorders include diabetic retinopathy, Age-related macular degeneration (ARMD), and other possible ocular conditions (3).

They cause vasodilation of blood vessels (4), which helps in regulating blood pressure. Consequently, they improve microcirculation and venous function.

Lowering blood cholesterol level:

A research-based trial involving people with a history of diabetes and hypertension were administered with a Quercetin supplement regularly.

Due to anti-oxidant properties, bioflavonoids minimize the oxidation of low-density lipoproteins (LDL) (5). This, in turn, lowers down the cholesterol levels in the blood.

Treating Eczema:

The most common type of eczema is atopic dermatitis. Research (6) suggests that Quercetin inhibits the secretion of mast cells. Mast cells trigger certain reactions, which is often the pathophysiology behind atopic dermatitis.

The suppression of mast cells means Quercetin relieves people suffering from eczema.

Controlling asthma:

As talked about earlier, Quercetin acts as a strong anti-inflammatory agent. This property helps Quercetin reduce asthma symptoms, such as suppressing bronchial activity, minimizing airway inflammation, and regulating mucus production (7).

Prevents Prostate Cancer:

Prostate cancer, one of the most common malignant tumors, affects males worldwide.

Studies (8) on Quercetin suggest that it minimizes the risk of developing prostate cancer by suppressing the expression of androgen receptors, triggering apoptosis in cancerous prostate cells, and inhibiting the proliferation of cancer cells.

Manages Hives And Other Skin Benefits:

Hives, which is characterized by red or pink bumps found on the skin. Hives usually occur due to any kind of allergic reaction by the body.

Quercetin’s anti-inflammatory properties prevent our immune system from releasing histamine, which is often primarily responsible for allergic reactions. This helps in managing symptoms of different allergic reactions, including hives (9).

Quercetin can also possibly prevent water loss from the skin, increase hydration and restore effective functioning.

Manage Blood Pressure:

Mice-based studies suggest that Quercetin helped in decreasing blood pressure values significantly. Systolic and diastolic blood pressure in mice dropped by 18% and 23%, respectively.

A systemic review and meta-analysis involving humans was performed, and the results were impressive as systolic and diastolic blood pressure values dropped by 5.6mm Hg and 2.8mm Hg, respectively (10).

Quercetin Dosage

Although you wouldn’t experience any side effects even after overdosing, the recommended dosage is 500mg-1000mg per day.

You can split your dosage in half by taking a morning capsule of 500mg and an evening capsule of 500mg.

Quercetin Phytosome vs Quercetin Dihydrate

While Quercetin itself offers tremendous benefits, the synergistic benefits of Quercetin with other supplements can prove magical.

Quercetin itself has low bioavailability.

A new derivative of Quercetin with lecithin as predominantly present is developed, which is called quercetin phytosome. Quercetin phytosome makes our body more efficient at absorbing compounds such as flavonoids. Thus, it has a better bioavailability (20 times more) than pure Quercetin, even at lower dosages.

Quercetin dihydrate, a synthetic chemical compound, contains water molecules as well as sugar molecules. Amongst all the supplements, quercetin dihydrate possesses the best bioavailability in the human body (11). Hence, it offers a lot of benefits due to better absorption.

Take-Home Message:

Picking from where we started, if you are a fan of herbal supplements and are looking for something real that improves all major body functions such as cardiovascular, metabolic, immune, neurological, and digestion, Quercetin should be your pick.

While Quercetin alone may offer you something, Quercetin supplements formulated with other extracts such as Phytosome, Dihydrates, and Bromelain will offer you a lot!

After reviewing all the brands, I would vote for Science. bio on top of others. This is not only because of the brand image but also of the exceptional after-sale services and 100% genuine product that they offer. Go and make your purchase right away!,pathogenesis%20of%20atopic%20dermatitis%20attacks.,proliferation%20(3%2C4).
