Monterey Pine Bark Extract
Also known as: Pine Bark Extract, Maritime Pine Bark Extract, Pycnogenol, Pinus radiata extract, Monterey Pine Bark Extract
Overview
Monterey Pine Bark Extract is derived from the bark of *Pinus radiata*, rich in bioflavonoids, particularly proanthocyanidins (OPCs). It functions as an antioxidant and anti-inflammatory supplement and is marketed for various health benefits including cardiovascular support, cognitive improvement, eye health, and management of chronic conditions like diabetes and osteoarthritis. The extract is generally considered safe, but the current research base is limited by small sample sizes and inconsistent outcome measures, leading to a low quality of evidence in many studies.
Benefits
Research indicates that Monterey Pine Bark Extract may improve cardiovascular health by lowering LDL cholesterol, increasing HDL cholesterol, and reducing blood pressure, as demonstrated in meta-analyses of randomized controlled trials (RCTs). It has also shown potential in lowering inflammatory markers like C-reactive protein. Cognitive improvement has been observed in patients with mild cognitive impairment, and benefits for managing diabetes have been noted. Although evidence supports these benefits, further high-quality studies are necessary to confirm long-term efficacy and clinical significance.
How it works
Monterey Pine Bark Extract exerts its effects primarily through its antioxidant properties by scavenging free radicals and modulating inflammatory pathways. Its proanthocyanidins stimulate endothelial nitric oxide synthase, which enhances cardiovascular function, while also mitigating neuroinflammation, thereby potentially benefiting cognitive function. The extract's compounds interact with various body systems to support health, particularly cardiovascular and neurological.
Side effects
While generally regarded as safe, Monterey Pine Bark Extract has limited evidence on its adverse effects, with no widely reported common effects. Uncommon or rare side effects have not been consistently documented, and no significant drug interactions have been reported. However, individuals with pre-existing health conditions or on medication should exercise caution. Safety in pregnant or breastfeeding women and children has not been fully established, recommending medical consultation prior to use. Overall, rigorous studies are needed to better understand the safety profile.
Dosage
The optimal dosage of Monterey Pine Bark Extract varies between 120 to 200 mg daily, with some studies indicating dosages up to 340 mg may be beneficial. The minimum effective dose is not clearly established, but doses ranging from 60 to 340 mg have been commonly utilized. There is no defined maximum safe limit, although doses as high as 480 mg have been tolerated without significant adverse effects. As the extract is readily absorbed, it may be taken in tablet or capsule form according to manufacturer guidelines, although no specific timing recommendations exist.
