Quercetin: Our Favorite Flavonoid

When it comes to powerful flavonoids that can protect our health, Quercetin is at the top of the list.

Flavonoids are a group of polyphenols, which are plant-based antioxidants. Flavonoids are responsible for providing fruits and vegetables with their vibrant colors. As it possesses antioxidant qualities, quercetin helps to reduce oxidative stress, reduce inflammation and fight off free radicals. By doing so, it helps to provide a wide range of health benefits.

Quercetin Health Benefits

1. Helps manage diabetes

While manageable, severe cases of diabetes can lead to amputation and eye disorders such as glaucoma and cataracts.

According to a study published in the journal Frontiers in Pharmacology, quercetin may help diabetics by fighting against the toxins that may cause the above-mentioned health complications.

2. Maintains neurological health

When free radicals attack the brain, they increase the risk for neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

According to a study done on mice, quercetin won’t only boost brain activity, but it can also help to regenerate damaged brain cells.

3. Offers cancer protection

Quercetin fights against free radicals, which can thus help lower the risk of cancer.

According to an animal study published in the journal Oncology Reports, this flavonoid helped to reduce the growth of prostate cancer cells in rats.

In regards to other types of cancer, an observational study revealed that quercetin-rich foods can help lower the risk of lung cancer. In addition, separate studies have also found that the risks for breast and colon cancer are also lowered (1,2).

Additionally, a study published in the journal Nutrients revealed that our favorite flavonoids can also help to ease the severity of asthma attacks.
