Pterostilbene is an antioxidant polyphenolic compound from the same family as resveratrol, found in blueberries, grapes and walnuts. This polyphenol has attracted attention in the field of anti-aging due to its antioxidant and anti-inflammatory properties and its potential impact on longevity. It has a similar structure to resveratrol, but with better biological activity due to its properties, being more easily absorbed by the body and offering longer-lasting effects.

Its benefits are:

-Sirtuin 1 activation (SIRT1): Like resveratrol, pterostilbene can activate sirtuins, proteins associated with the regulation of longevity and cell repair.

- Greater antioxidant power than resveratrol: Due to its chemical structure, pterostilbene has greater bioavailability and a more powerful antioxidant effect than resveratrol, helping to reduce oxidative stress and prevent cellular ageing.

- Cardiovascular protection: Helps reduce LDL cholesterol and improves endothelial function, protecting against cardiovascular disease.

- Improves insulin sensitivity: May help regulate blood glucose, reducing the risk of insulin resistance and type 2 diabetes.

- Neuroprotection and cognitive health: Acts in neuronal protection against cognitive decline and may play a role in preventing neurodegenerative diseases such as Alzheimer's.

In comparative terms - Pterostilbene vs. Resveratrol: 

- Bioavailability: Pterostilbene is better absorbed and has a longer half-life in the body.

- Efficacy: It has more powerful antioxidant and anti-inflammatory effects

- Supplementation: It is generally used in lower doses than resveratrol due to its higher potency.

 

Normally recommended dosage of Pterostilbene: 

50 - 150 mg/day - For health maintenance and antioxidant action.
150 - 300 mg/day - For cognitive and cardiovascular support.
up to 500 mg/day - In specific cases, under professional supervision.
