Over the years, research on resveratrol has expanded to explore its impact on a variety of biological processes related to aging. Studies have investigated its role in inflammation reduction, sirtuin activation, and its potential to mimic the effects of [[Caloric Restriction|caloric restriction]] – one of the few scientifically supported interventions known to extend lifespan in various organisms. The body of research has grown to include clinical trials aiming to understand the effects of resveratrol on human health and longevity. | Over the years, research on resveratrol has expanded to explore its impact on a variety of biological processes related to aging.

=== Anti-Inflammatory Effects === | === Anti-Inflammatory Effects === | ||
The anti-inflammatory effects of resveratrol are significant in the context of aging. Chronic inflammation is implicated in numerous age-related conditions, and resveratrol’s ability to modulate inflammatory responses could be pivotal in mitigating the impacts of such conditions. | |||
=== Sirtuin Activation and Regulation === | === Sirtuin Activation and Regulation === | ||
Resveratrol is known to activate [[Sirtuins|sirtuins]], a family of proteins associated with aging and longevity. Sirtuins regulate various cellular processes, including DNA repair, metabolism, and stress resistance, and are believed to extend lifespan by promoting cellular stability and survival. | |||
=== Impact on Telomeres === | === Impact on Telomeres === | ||
[[Telomeres]] are the protective caps at the ends of chromosomes that shorten as cells divide. Resveratrol is suggested to influence telomere length and function, potentially delaying [[Cellular Senescence|cellular senescence]] and extending the lifespan of cells. | |||

Resveratrol is believed to extend lifespan through its interaction with certain proteins and genes associated with aging. Studies in various organisms, including yeast, worms, flies, and mice, have shown promising results, indicating an increase in lifespan with resveratrol supplementation. | Resveratrol is believed to extend lifespan through its interaction with certain proteins and genes associated with aging.

In {{ | In {{pmid|17086191}} mice fed a standard diet, high-calorie diet or high-calorie diet plus resveratrol. The study found that resveratrol helps mice on a high-calorie diet have similar health benefits to mice on a regular diet. This includes better lifespan, movement, insulin response, organ health, and improved mitochondrial function. Importantly, these benefits happened without the mice losing weight. | ||

After consumption, 77-80% of resveratrol gets absorbed into the bloodstream through active transport via the intestinal epithelial cells. Once in the bloodstream, it associates with albumin and lipoproteins. Despite its efficient absorption, resveratrol possesses a short half-life of around 1.5 hours. This is attributed to its rapid absorption in the intestine and subsequent degradation in the liver. A significant amount of ingested resveratrol, approximately 49–61%, is eventually excreted through urine. {{ | After consumption, 77-80% of resveratrol gets absorbed into the bloodstream through active transport via the intestinal epithelial cells.

In 2021 [[Randomized Controlled Trial]], participants receive a single dose of resveratrol 2500 mg, with piperine in 0 mg, 5 mg or 25 mg dose. Despite the observation of piperine coadministration significantly increasing bioavailability ([[Cmax|C<sub>max</sub>]] and [[AUC|AUC)]] of resveratrol in [[C57BL/6 mice|C57BL]] mice, no significant increase in resveratrol or decrease in resveratrol glucuronide could be observed in healthy adults taking 2500 gm of resveratrol with piperine (5 or 25 mg) as compared to resveratrol alone. {{ | In 2021 [[Randomized Controlled Trial]], participants receive a single dose of resveratrol 2500 mg, with piperine in 0 mg, 5 mg or 25 mg dose.

===Safety === | ===Safety === | ||
Resveratrol is generally considered safe when taken in recommended amounts, but excessive consumption can lead to side effects. In a study, it was found to be safe as no severe adverse reactions were observed based on clinical, biochemical, or hematological analyses. | |||
===Side Effects=== | ===Side Effects=== | ||
Some people may experience gastrointestinal issues, headaches, or a feeling of jitteriness. In the mentioned study {{pmid|20935227}}, the majority of adverse events in the higher doses (2.5g and 5.0g) were gastrointestinal symptoms, including nausea, flatulence, abdominal discomfort, and diarrhea. Symptoms typically began 2-4 days into the regimen and improved as the day progressed but would return after the next dose. They resolved within 2 days of completing the 29-day regimen. | |||
