2. Maritime Pine Bark Benefits
Let’s have a look at some of the most important benefits of Maritime Pine.
1. Crosses blood brain barrier and reduces oxidative stress
Many antioxidants struggle to reach the brain but OPCs seem to be particularly adept at crossing the blood-brain barrier. This feature makes them specifically suited to rid the brain of potentially damaging free radicals. This mechanism also has the effect of lowering oxidative damage inflicted on brain cells. This helps promote long-term brain health and performance.
Other than granting cognitive benefits, reducing oxidative stress also has a huge impact on other aspects of health. For instance, more and more diseases are being linked to free radical damage. But reducing their numbers can help prevent the onset of conditions like certain cancers, diabetes, asthma, arthritis, and atherosclerosis to name just a few.

2. Boosts Nitrous Oxide (NO)Production
Another property of OPCs is to boost the production of Nitrous Oxide. For blood vessels to function optimally, they need NO which lets them dilate and retain healthy levels of blood pressure. Now blood vessels release NO through their endothelium or interior walls. Once released, NO relaxes constricted blood vessels and expands them. This allows more nutrient-rich blood to flow through and reach all parts of the body including the brain. This brings me to the point of cerebral circulation in particular.
With more blood reaching the brain effectively, there is enhanced delivery of oxygen and nutrients to the brain cells. Areas of the brain that may not be receiving sufficient blood also start getting the fuel they need to thrive. In this manner, age-related cognitive decline that may be caused by degradation of blood vessels can be prevented or at least delayed.
By protecting brain health, you can also protect your long-term mental performance.
In the same manner, improved circulation to the heart can prevent the blood from clotting and arterial restriction brought on by stress. Studies have also shown that the OPCs found in Maritime Pine bark extract can strengthen the lining of blood vessels as well as of capillaries.
3. Improves Cognitive Performance and Brain Function
Supplementing with pine bark extract seems to have a significant effect on memory, focus, decision making, and mood. Evidence gathered from a number of different studies indicates the brain-boosting power of this remedy. For instance, one 12 week study conducted in Italy involved 60 subjects, half of whom were given pine bark extract daily while the other half received a placebo.
After 12 weeks the group receiving pine bark extract showed greater improvement with free radicals reduced by 30.4%. They also exhibited improved spatial memory, alertness, anxiety, and contentedness. 
In another study that examined the effects of pine bark extract on working memory involved 101 subjects in a double bind, placebo-controlled study. Participants received 150mg of the extract every day for three months. Results were compiled based on cognitive tasks including attention, working memory, episodic memory, and psychomotor performance. The group taking the extract developed a better working memory. .

4. Enhances Athletic Performance
Because it is an antioxidant, acts as a vasorelaxant, and has some anti-inflammatory potential, Maritime Pine bark extract can also help with improving physical performance. Together, these mechanisms can have a supportive outcome of the athletic performance. This happens by bringing oxygen, and hence energy, to the muscles more effectively. The same will also have an effect on speeding up recovery after exercise and reducing cramps, aches, and pains once the workout is over.
Along with performance, pine bark extract also seems to improve athletic stamina. 147 participants involving recreational athletes taking 100mg of the extract over an 8-week training program exhibited improved endurance levels. Professional athletes preparing for a triathlon took 150mg daily with improving their overall time, enhancing swimming, biking, and running scores while reducing cramps and muscle pain. 
5. May Improve ADHD Symptoms
The antioxidant content of Maritime Pine Bark can help balance the immune system. The same can also lower inflammation and reduce oxidative stress in ADHD. Additionally, individuals with ADHD also have higher than normal adrenaline and dopamine levels which can aggravate oxidative stress. One clinical trial administered a controlled dosage of pine bark extract to 57 ADHD children for one month. After the trial period was over, the children exhibited reduced hyperactivity symptoms by lowering levels of dopamine, adrenaline and increasing the antioxidant glutathione. 
6. Lowers Blood Glucose
Pine bark can potentially lower blood glucose levels and improve blood sugar readings. But results are only observed if administered for at 12 weeks. One such trial with 77 participants received the extract administered at 100mg daily for 12 weeks. Results showed that not only did blood sugar levels lower but so did HbA1c which is a marker for long-term blood glucose levels.  Taking the extract resulted in significantly lowered blood glucose levels and improved endothelial function.
Another similar study of 48 individuals with diabetes and hypertension receiving 125mg daily also showed promising results. More than half the participants were able to normalize their blood pressure as well as reduce medication intake for the condition. This improvement also reduced their risk of heart disease complications. 
7. Improves Skin Health
Natural antioxidants have long been known for their skin-friendly benefits. In the same manner, pine bark extract has been studied for reducing skin damage. The skin is extensively exposed to toxins, pollutants, UV rays and other factors that compromise its health and defense mechanism.
Pine bark extract may be able to protect the skin from many of these factors including UV rays, hyperpigmentation, and uneven tanning. At the same time, it may also improve skin strength, elasticity, and hydration.
Its use as an anti-aging agent was studied in a clinical trial with 20 post-menopausal women. Receiving 12 weeks of supplementation improved the skin’s elasticity and hydration. The same also enhanced gene activity that produces collagen and hyaluronic acid in the body.
