Flavonoid Vs Polyphenol Vs Phytochemical (2023)
Flavonoids, polyphenols, and phytochemicals are terms often used to describe different types of bioactive compounds found in plants, but there is some overlap between them as well.
Flavonoid Vs Polyphenol Vs Phytochemical
Phytochemicals cover all bioactive compounds discovered in plants, including polyphenols like flavonoids as well as other non-polyphenolic substances. Polyphenols are a broader category of compounds that include flavonoids as well as other subgroups, whereas flavonoids are a specific type of polyphenol.
While these terms have distinctions, they are often used interchangeably in casual language and scientific literature due to their close relationship in the context of plant-based compounds and their potential health benefits.
Here are the key differences and relationships between these terms:
a. Flavonoids
- Flavonoids are a subgroup of polyphenolic compounds.
- Flavonoids in food are generally responsible for colour, taste, prevention of fat oxidation, and protection of vitamins and enzymes.
- Flavonoids have antioxidant properties and are known for their potential health benefits. A study suggests that the risk of some chronic diseases may be lower at higher dietary flavonoid intakes.
- Common examples of flavonoids include quercetin, kaempferol, and anthocyanins.
b. Polyphenols
- Polyphenols are a larger and more general category of naturally occurring compounds found in plants.
- They are broadly dived in four classes; Phenolic acids, flavonoids, stilbenes and lignans.
- Polyphenols are known for their potential health benefits. Animal, human and epidemiologic studies show that various polyphenols have antioxidant and anti-inflammatory properties that could have preventive and/or therapeutic effects for cardiovascular disease, neurodegenerative disorders, cancer, and obesity. (R)
c. Phytochemicals
- Phytochemicals are a broad term that encompasses all bioactive compounds found in plants.
- This term is a more general one that encompasses a wide range of bioactive compounds found in plants, including flavonoids and polyphenols.
- Phytochemicals possess many biological activities and health benefits, such as antioxidant and free radical scavenging abilities, anti-inflammatory action, anticancer, anti-aging, and protective action for cardiovascular diseases, diabetes mellitus, obesity and neurodegenerative diseases. (R)
Flavonoids Supplements
a. Flavonoids Supplements - Quercetin
Quercetin is a type of flavonoid present in many fruits, vegetables, and grains. It’s one of the most abundant antioxidants in the diet and plays an important role in helping your body combat free radical damage, which is linked to chronic diseases.
Quercetin Benefits
Quercetin has been linked to the following health benefits:
- Possessing anti-inflammatory, antioxidant properties that can help combat certain diseases. One study found that 500 mg of quercetin a day could improve symptoms of rheumatoid arthritis.
- Helping prevent cancer cell growth from breast, colon, prostate, endometrial and lung.
- Counteracting allergic reactions and helping with immune responses.
- Helping to prevent osteoporosis
- Addressing cognitive decline, including Alzheimer’s and dementia.
- Assisting in control of blood pressure. A study in 2002 found that quercetin can have vasodilator effects.
- Potentially helping to lower blood sugar levels. One study found that dosages of 500 mg per day “significantly reduced” fasting glucose levels.

I've been taking various brands of quercetin with bromelain for four years now and this one is my favorite. The best value for the cost, and also the move effective. This summer started out to be more wretched than other years, allergy-wise, and I switched to these to see how they'd work and I've never been happier. I use this brand for another supplement so I was already familiar with them and was willing to try it out. I'm not sure why the review asked about pain relief, because that is not what this is used for, so I X'd it out. But otherwise, very good product, and I've already told two people about it.
b. Flavonoids Supplements - Citrus Bioflavonoids / Vitamin C
Vitamin C is an essential nutrient which cannot be produced by humans (Nutrients. 2017). Because your body doesn't produce or store it, you need daily vitamin C for continued health. Vitamin C may be one of the most well-known immune nutrients that protect against immune deficiencies and which supports the prevention and recovery from the common cold and upper-respiratory issues, and also protects your cardiovascular system, eyes, skin, and other parts of your body.
Vitamin C is a particularly unique nutrient because it also functions as an antioxidant that protects your cells against potential damage.

As a diabetic of 43 years, I've done pretty well. I can still see and pee and have all my feet and toes.
I recently learned how high dose vitamin C can get rid of those age spots that mar our complexion as we get older. I had a big dark spot on my face go away and today I looked down at my feet and one of two scars was gone and the other was going. They had been there for several years. and They say diabetics don't heal well.
Our bodies need Vitamin C to make collagen and to keep our skin healthy we all need more than the RDA, but Diabetics even more so. Diabetics use up our vitamin C quicker than most other people and it is a strong anti-oxidant. Even though I am doing fairly well, I did have a heart attack 10 years ago. My arteries were brittle and since I wasn't taken vitamin C at that time, my body didn't have the materials to repair and keep my arteries flexible.
I take this C and I also take another Liposomal Vitamin C 1:1. I have taken up to 40,000 mg in a day spread out throughout the course of the day. Like 2,000 and hour. No ill effects and with some pleasant surprises such as I described.
c. Flavonoids Supplements - Apigenin
Apigenin is a natural compound that belongs to the flavonoid class of polyphenols. Apigenin is present in some fruits such as grapefruit, plant-derived beverages and vegetables such as parsley, onions, oranges, tea, chamomile, wheat sprouts.

- Anti-Inflammatory Effects: Apigenin is a very effective anti-inflammatory agent, which can be beneficial for conditions involving inflammation, such as arthritis.
- Potential Cancer Prevention: Apigenin may plays a vital role in managing cancer’s development and progression. This flavonoid seems to have anti-cancer activities via the modulation of a various cell signaling pathways including angiogenesis, apoptosis, cell cycle and various other genetic pathways. Further studies are needed to confirm this statement.
- Sleep Improvement: Chamomile flower extract, with more than 2.5 mg of apigenin, was examined for its preliminary efficacy and safety for improving sleep and daytime symptoms in patients with chronic insomnia. Further studies are still needed to investigate these conclusions. (R)
- Heart Health: Apigenin may prevents cardiovascular diseases via antioxidant and anti-apoptotic mechanisms in vascular endothelial cells and cardiomyocytes. (R)
- Skin Health: Apigenin has been used for skin care. According to a study, topical apigenin improves epidermal permeability barrier function by stimulating epidermal differentiation, lipid synthesis and secretion, as well as cutaneous antimicrobial peptide production.

FAQs
a. Phytochemicals-Rich Foods
There are many different fruits, vegetables, grains, legumes, and herbs that are high in phytochemicals. Flavonoids, carotenoids, and glucosinolates are a few of the natural substances that can be found in a variety of colorful produce, including berries, leafy greens, carrots, and tomatoes. These advantageous compounds are also common in whole grains, cruciferous vegetables like broccoli and cauliflower, as well as spices like turmeric and garlic, as well as whole grains.
b. Can a lack of phytochemicals in the diet can lead to deficiency disease?
Yes. If an individual's diet lacks an adequate intake of phytochemical-rich foods, they can get phytochemical deficiency disorders which may include a higher susceptibility to chronic diseases like cancer, heart disease, and neurodegenerative conditions due to reduced antioxidant protection against free radicals.
Moreover, it can weaken the immune system, potentially leading to increased vulnerability to infections, and it may also contribute to chronic inflammation-related health problems.
