Pycnogenol 100 by Allergy Research Group

If your legs feel heavy after long days or flights, pycnogenol is one of the few botanicals with solid data for venous circulation. It also fits adults watching blood pressure at home who want a gentle adjunct, and those focused on skin hydration and photoprotection. A maintenance dose like this suits people with mild symptoms; trials in more pronounced venous insufficiency often used higher daily totals. If your hs-CRP (a general inflammation marker) runs high, modest improvements are reported in some responders.

Pycnogenol is a standardized French maritime pine bark extract rich in procyanidins and bioflavonoids. These compounds enhance nitric oxide (the gas your arteries use to relax), which can ease resistance in blood vessels, and they stabilize collagen and elastin in capillaries, which helps reduce leg swelling. They also temper platelet stickiness, shifting thromboxane signaling, and act as antioxidants that lower lipid peroxidation. Across trials, this translates to small blood pressure reductions and occasional drops in hs-CRP in 4 to 12 weeks.

Take one capsule once or twice daily, with or without food. Consistency matters more than timing. Skin and hydration outcomes usually need 6 to 12 weeks, circulation benefits 4 to 8 weeks. Many studies used 100 to 200 mg per day, so if your goals are leg swelling or blood pressure, clinicians often start at 100 mg and reassess; higher total daily dosing can be considered if response is incomplete.

Because pycnogenol can reduce platelet aggregation (platelet clumping that helps blood clot), use caution with blood thinners like warfarin and with antiplatelet drugs such as clopidogrel or daily aspirin; discuss with your clinician and monitor for bruising. It can slightly lower glucose, so if you track Fasting Glucose or HbA1c and use diabetes medications, watch for additive effects. Skip during pregnancy and breastfeeding due to limited data, and avoid if you have a known pine allergy.
