Another significant mechanism of Pycnogenol is its anti-inflammatory properties. Pycnogenol inhibits the activity of pro-inflammatory enzymes like cyclooxygenase (COX) and lipoxygenase, and reduces the production of inflammatory cytokines such as interleukins and tumor necrosis factor-alpha (TNF-α). This anti-inflammatory effect is particularly beneficial in managing conditions like osteoarthritis and chronic venous insufficiency, where inflammation plays a critical role. For instance, a study published in "Redox Report" found that Pycnogenol significantly decreased C-reactive protein (CRP) levels, a marker of inflammation, in patients with osteoarthritis (Belcaro et al., 2008).

Pycnogenol also enhances endothelial function, which is crucial for maintaining healthy blood vessels. It does this by increasing the production of nitric oxide (NO), a molecule that helps relax blood vessels, improve blood flow, and reduce blood pressure. A study in "Hypertension Research" demonstrated that Pycnogenol supplementation significantly augmented endothelium-dependent vasodilation by increasing NO production (Nishioka et al., 2007). This vasodilatory effect is beneficial in conditions like hypertension and chronic venous insufficiency, where improved blood flow can alleviate symptoms.

Additionally, Pycnogenol has been shown to modulate blood glucose levels by enhancing insulin sensitivity and improving glucose uptake in cells. This is particularly beneficial for individuals with type 2 diabetes. A systematic review and meta-analysis in "Pharmacological Research" reported that Pycnogenol supplementation significantly reduced fasting blood glucose and HbA1c levels, indicating improved glycemic control (Malekahmadi et al., 2019).
