Longevity

Senolytic effects of quercetin in an in vitro model of pre-adipocytes and adipocytes induced senescence – Cell study

Everything You Need To Know About Quercetin

Quercetin is a naturally occurring flavonoid found in various fruits and vegetables, such as apples, onions, and berries.

Quercetin, fisetin, and luteolin all share antioxidant, anti-inflammatory, and senolytic properties, though quercetin’s effects are broader and less targeted, impacting senescent cells, inflammation, and allergy response. Fisetin is particularly effective in targeting senescent cells, while luteolin is primarily studied for its impact on brain health.

Quercetin acts as a senolytic by targeting inducing cell death in senescent cells. These ageing cells, which no longer divide, release pro-inflammatory factors. Quercetin helps remove these cells by inhibiting pathways that promote cell survival, thereby reducing inflammation associated with senescent cell accumulation.

Quercetin has also been shown to stabilise mast cells, preventing the release of histamine, the compound responsible for allergic reactions. It blocks histamine release by inhibiting the activation of receptors in immune cells, making it effective at improving allergic responses at the cellular level.

Healthy senescent cell clearance is a natural process that maintains cellular health. However, as we age, the efficiency of this clearance declines due to factors like weakened immune surveillance, allowing senescent cells to accumulate. This accumulation heightens inflammation and cellular damage. Clearing these cells through senolytic action helps reduce chronic inflammation and support cellular health.

By clearing senescent cells and reducing chronic inflammation, quercetin may help prevent the buildup of cellular damage, a hallmark of ageing, as well as reducing the demands on the body to combat it. Its antioxidant properties further protect cells from oxidative stress, supporting resilience against age-related decline.

Consider the following statements. If you relate to one or more, then Quercetin may be the support you are searching for:

  • I’m interested in exploring the potential of senolytics like quercetin to support longevity.
  • Seasonal allergies affect my quality of life, and I’m searching for a natural remedy to alleviate these symptoms without relying on conventional medications.
  • Despite trying various supplements, I still struggle with inflammation and am looking for a natural alternative that could help reduce it.
  • I’ve heard about the benefits of antioxidants in combating oxidative stress.
  • A healthcare professional recommended that I try quercetin.

Frequently Asked Questions

Multiple studies have indicated that quercetin may help with seasonal allergies by stabilising Mast cells. These cells release a chemical called Histamine in the body. When histamine gets too high, it can result in allergies. Quercetin can help by lowering the amount of histamine that is released, and in this way, it may help to reduce seasonal allergies.

Quercetin and Luteolin are both senolytics. Their off target effects are what set them apart. Quercetin in addition to being a senolytic has been shown to be effective at helping to regulate blood sugar whilst also lowering histamine levels, making it a possibly effective for seasonal allergies. Aside from its senolytic effects Luteolin has also been shown to decrease levels of CD38, a main user of NAD, and therefore may preserve NAD levels in the body.
