Pine Bark Extract (Pinus pinaster)

Pine Bark Extract (PBE) is derived from the bark of the French maritime pine tree (Pinus pinaster). PBE contains several bioactive compounds, including flavonoids, catechins, and procyanidins, which are responsible for its potential health benefits. PBE has been studied for its potential effects on cardiovascular health, inflammation, and brain function.

Improving cognitive function
PBE has been shown to improve cognitive function, including memory and attention. A randomized, double-blind, placebo-controlled study found that PBE supplementation significantly improved memory and attention in healthy adults (Kean et al., 2015). Another study found that PBE improved cognitive function in individuals with mild cognitive impairment (MCI) (Valls-Pedret et al., 2012).

Reducing inflammation
PBE has been shown to have anti-inflammatory effects. A randomized, double-blind, placebo-controlled study found that PBE supplementation significantly reduced levels of the inflammatory marker C-reactive protein (CRP) in individuals with metabolic syndrome (Kim et al., 2012). Another study found that PBE reduced inflammation and oxidative stress in individuals with type 2 diabetes (Zhang et al., 2015).

Improving cardiovascular health
PBE has been shown to have potential benefits for cardiovascular health, including reducing blood pressure and improving blood lipid profiles. A randomized, double-blind, placebo-controlled study found that PBE supplementation significantly reduced systolic blood pressure and improved lipid profiles in individuals with metabolic syndrome (Kim et al., 2012). Another study found that PBE improved endothelial function and reduced blood pressure in individuals with early-stage hypertension (Zhang et al., 2015).

Overall, PBE appears to have potential health benefits, particularly in improving cognitive function, reducing inflammation, and improving cardiovascular health.
