Health Benefits of Pycnogenol
With only a little bit of research, it’s easy to see that there’s a whole slew of benefits of pycnogenol. But how much of this is marketing puffery, and how much is science? Read on!
Pycnogenol Skin Benefits
Many people like to use pycnogenol for skincare. But does science back up the hype? Research over the past few decades has started to verify pycnogenol’s skin benefits. Here’s a brief overview.
Skin Hydration and Elasticity
Several studies have found that pycnogenol can help with healthier skin by boosting hydration and elasticity.2
One study looked at the skin’s response to supplementing pycnogenol in 20 healthy women.3 Their skin was examined with several testing methods before and after the 12-week trial. By the end, pycnogenol had significantly improved hydration and elasticity of the skin. Interestingly, this effect was strongest in women who had dry skin before the trial.
Pycnogenol and Psoriasis (Scaly, Flaky Skin)
Psoriasis is a skin condition in which dead skin cells rapidly build up in patches. Symptoms include flaky, scaly, itchy, dry, bumpy, and/or reddened skin. A few studies have indicated that pycnogenol may help with psoriasis.
One study examined the effects of pycnogenol on subjects with moderate to severe psoriasis. 4 After a 12-week trial, there were significant decreases in symptoms in the pycnogenol group compared to the control. Notably, they showed a greater reduction in psoriasis surface area and severity. There was also significantly less flaking and significantly more skin moisture in the pycnogenol group.
Black seed oil, an extract from a Middle Eastern herb, has similarly been shown to reduce psoriasis symptoms. Refer to our complete black seed oil guide for more information.
Pycnogenol and Melasma (Dark Splotches on Skin)
Melasma is a skin condition manifested by dark splotches, often on the face. These darker areas are the result of hyperpigmentation, typically caused by increased sun exposure.
Many users of pycnogenol claim that the woodsy extract is able to alleviate these dark patches associated with melasma. Supporting these claims, there is indeed some research to suggest pycnogenol may help with melasma.
One notable study looked at the effects of pycnogenol on thirty women suffering from melasma.5 Each subject took 75 milligrams of pycnogenol per day for 30 days. The research measured the total areas of melasma, as well as pigmentation level (skin shade). At the end of the trial, the total melasma surface area had decreased by roughly 25%, and pigmentation had also decreased (i.e., lighter skin).
These findings suggest pycnogenol may be effective in treating melasma, with visible improvements in as little as 30 days. It’s also worth noting that 75 milligrams of pycnogenol daily is a low dose compared to many other studies. Further research is needed to determine whether higher doses are more effective.
Pycnogenol and Erythema (Skin Redness)
Erythema, commonly known as skin redness, can have a lot of different causes. From sunburn to chafing clothes, to genetic factors, most people will experience skin redness from time to time. Some research indicates pycnogenol may help reduce erythema.
One study examined the effects of pycnogenol on ultraviolet-induced redness (essentially, sunburn).6 The study found that with increased pycnogenol supplementation, significantly more ultraviolet light was needed in order to cause redness. Put simply, the skin was more resistant to sunburn. This was observed with doses of 1.10 milligrams and 1.66 milligrams per kilogram of body weight for 4 weeks each.
Brain Health: Pycnogenol’s Nootropic Benefits
Pycnogenol is fairly popular as a nootropic supplement, a class of supplements that improve cognitive function. Here are a few ways research has shown that pycnogenol works as a nootropic supplement.
One study examined the effects of pycnogenol supplementation in healthy elderly individuals.7 Subjects took 150 milligrams of pycnogenol daily for 3 months. Throughout the trial, they demonstrated improvement in several cognitive areas, including both short-term and long-term memory.
Another study performed on healthy elderly subjects similarly found an improvement in memory.8 After taking 100 milligrams of pycnogenol daily for 12 months (by far one of the longest trials), subjects reported significantly improved long-term memory. This was reported via a standardized cognitive performance questionnaire.
Another study, this time with students aged 18-27, similarly found memory-boosting effects with pycnogenol.9 After 8 weeks of supplementation, those that took pycnogenol scored statistically better on cognitive tests than a control group. Notably, the pycnogenol group demonstrated better memory.
In one of the studies cited above, pycnogenol was also associated with a boost in focus.10 In healthy elderly subjects, 150 milligrams of pycnogenol daily resulted in a significant increase in focus and attention.
Similar findings were noted in the above-cited study on students.11 After 8 weeks of pycnogenol supplementation, students demonstrated increased sustained attention compared to a control group.
Neurological damage from oxidative stress plays a big part in the progression of Alzheimer’s disease. As such, pycnogenol’s antioxidant effects have been examined in the context of this disease.
One animal study did find that pycnogenol may help slow the progression of Alzheimer’s disease.12 In rats, pycnogenol and vitamin E were supplemented in order to reduce artificially-induced, controlled levels of oxidative stress. After 2 weeks, the control rats demonstrated significant cognitive decline. The pycnogenol rats, on the other hand, demonstrated much less decline.
A very interesting study found that pycnogenol may help protect the brain following a traumatic brain injury.13 Regardless of dose, the researchers found that administering pycnogenol via IV injection significantly reduced indicators of brain trauma in rats. They concluded that pycnogenol may exhibit neuroprotective effects following brain trauma. Other animal research has led to similar findings.14
Effects on ADHD
One study examined the effects of pycnogenol in 61 children with attention-deficit/hyperactivity disorder (ADHD).15 For 4 weeks, one group took 1 milligram of pycnogenol daily per kilogram of bodyweight. The other group was given a placebo. The results showed that pycnogenol significantly reduced hyperactivity while improving focus and hand-eye coordination. Furthermore, the subjects relapsed back to their original condition within one month after discontinuing pycnogenol. These findings suggest pycnogenol may be effective against ADHD symptoms in children.
Other Health Benefits
Pycnogenol has been praised as a way to support a lot more than just skin and brain health. Here’s a brief overview of its other research-backed benefits.
Reduced Risk of Heart Disease
Several studies have indicated that pycnogenol may be able to reduce the risk of heart disease.16
One test tube study found that pycnogenol was able to stimulate nitric oxide production.17 Nitric oxide, in turn, decreases levels of low-density lipoprotein cholesterol (“bad” cholesterol) in the body. It also inhibits plaque buildup in the arteries. All of this indicates that pycnogenol may lead to a significant reduction in the risk of heart disease.
A human study found that pycnogenol may be able to reduce high blood pressure.18 The 12-week, the 58-subject study examined the effects of 100 milligrams of pycnogenol daily compared to a control. The study found a mild reduction in blood pressure, indicating that pycnogenol may be effective against mildly high blood pressure.
A meta-analysis of three trials examined the effects of aspirin vs. pycnogenol on blood platelet clumping in smokers.19 Platelet aggregation leads to blood clots, which are helpful for stopping the bleeding but are dangerous when they occur in veins and arteries. Smoking increases platelet aggregation, which in turn increases the risk of heart disease.20
The meta-analysis found that pycnogenol was effective in reducing blood platelet clumping. Furthermore, while aspirin significantly increased bleeding time due to decreased clumping, pycnogenol didn’t. The researchers found that one 200-milligram dose of pycnogenol was able to reduce smoking-induced blood platelet clumping for over 6 days. These findings suggest that pycnogenol may reduce blood clot-related heart disease risk, particularly in smokers.
Several studies have found that pycnogenol may be effective in reducing swelling and inflammation.2122
One such study specifically examined blood flow and swelling in the legs of forty subjects.23 Twenty of the subjects took 300 milligrams of pycnogenol daily for 60 days. Compared to the control group, pycnogenol was associated with a significant reduction of pain and swelling when measured at both 30 and 60 days. Roughly 60% of the pycnogenol-treated subjects had no swelling at all by the end of the trial. No such changes were noted in the control group.
These findings indicate that pycnogenol may be effective in reducing inflammation and swelling. In addition, it may be effective in reducing pain associated with these symptoms. Further research is needed on pycnogenol’s effects on swelling in other areas of the body.
Another study examined the effects of pycnogenol on 100 subjects with knee pain (osteoarthritis).24 For 3 months, one group supplemented 150 milligrams of pycnogenol daily while the other took a placebo. Following treatment, the pycnogenol group demonstrated a significant reduction in pain, while the control group had no change. These findings further suggest that pycnogenol may be effective in reducing pain and inflammation.
A few studies have shown that pycnogenol can be effective in fighting hostile microorganisms, such as bacteria and fungi.
One notable study examined the effects of pycnogenol against 23 different pathogenic (disease-causing) microorganisms.25 The study found even in concentrations as low as 0.025%, pycnogenol was able to counteract the growth of all 23 microorganisms. This indicates that pycnogenol may be effective in killing or suppressing disease-causing microorganisms, like bacteria and fungi.
Several studies have found that pycnogenol contains antioxidant compounds.2627 One such study noted significant antioxidant effects in subjects taking 150 milligrams of pycnogenol daily for 6 weeks.28 Such findings indicate that pycnogenol may be effective in free radical scavenging. This, in turn, would reduce the risk of oxidative stress, which can manifest symptoms such as fatigue, headache, and cognitive deficits.
Accelerated Wound Healing
One study examined the effects of pycnogenol on standardized wounds inflicted on rats.29 Gel was applied to the wounds as researchers monitored the wound size and level of scabbing. One group was treated with a gel containing 1% pycnogenol, one with 2% pycnogenol, one with 5% pycnogenol, and one without pycnogenol.
The gel-only group healed in an average of 15.4 days. The 1% pycnogenol group healed 1.6 days faster. The 2% group healed nearly 3 days faster than the control. The 5% pycnogenol group did heal faster than all others, but there was less of an increase over the 2% group. Furthermore, the pycnogenol groups were left with smaller scars following healing. These findings suggest that pycnogenol may be effective in wound healing and scar prevention.
Effects on Asthma
A few studies have suggested that pycnogenol may be effective against asthma symptoms.
One study sought to examine the effect of pycnogenol on asthma.30 Twenty-two patients completed the 8-week study. For the first 4 weeks, one group was given 1 milligram of pycnogenol daily per pound of bodyweight. The other group was given a placebo. For the last 4 weeks, the regimen was switched. The study found that pycnogenol was effective in reducing symptoms and biological markers of asthma. The researchers’ conclusion was that pycnogenol may be effective in managing chronic asthma.
Another study examined the effects of pycnogenol on 60 asthmatic subjects from 6-18 years old.31 Over the 3-month trial, subjects taking pycnogenol demonstrated significant improvement in asthma symptoms compared to the control. Furthermore, they were able to lessen or discontinue the use of inhalers more often than the control group. These findings indicate that pycnogenol may be effective against childhood asthma.
Diabetic Symptoms and Conditions
Although it’s no cure for diabetes, pycnogenol has been shown to have an effect on certain diabetic symptoms and conditions.32
For example, pycnogenol has been shown to lower glucose levels in diabetic subjects.33 In one study, researchers examined whether pycnogenol inhibits alpha-glucosidase (noting that pycnogenol itself does not increase insulin secretion).34 Put simply, alpha-glucosidase breaks down starches and sugars, increasing blood glucose levels.
The study did find that pycnogenol inhibited alpha-glucosidase. With lower levels of alpha-glucosidase, lower blood sugar levels were noted. This indicates that pycnogenol may be effective against hyperglycemia (high blood sugar) in diabetic individuals.
Another example is diabetic retinopathy, a condition caused by damaged blood vessels in the back of the eyes. Symptoms start with very mild vision problems, but can eventually lead to blindness.
One promising meta-study examined the effects of pycnogenol on slowing diabetic retinopathy. Researchers analyzed five different trials examining a total of 1,289 subjects. Their conclusion was that these studies overwhelmingly indicate that pycnogenol is effective in slowing and/or halting diabetic retinopathy. In some cases, vision actually improved.
Pycnogenol and Erectile Dysfunction
Some research indicates that pycnogenol may have an effect on erectile dysfunction.
As discussed above, pycnogenol has been shown to increase levels of nitric oxide in the body. Erectile dysfunction can be caused by low levels of nitric oxide. Because of this, one study sought to examine the effects of pycnogenol and l-arginine on erectile dysfunction.36
The design of the study could have been more thorough, but its results are promising. Forty men with self-reported erectile dysfunction underwent a 3-month trial. During the first month, they took only 1.7 grams of l-arginine daily. There was no statistically significant improvement in symptoms. In the second month, subjects began taking 80 milligrams of pycnogenol daily. At this point, 80% of the men reported normal erection. After taking 120 milligrams during the third month, 92.5% of the men reported normal erection. These findings suggest pycnogenol may be effective in treating erectile dysfunction.
For more information on l-arginine and its impact on fertility and sexual health, refer to our complete l-arginine guide.
Based on current research, the ideal dose for pycnogenol is 100 to 300 milligrams per day. Although there is currently no official recommended dosage, most studies on this supplement have used a daily regimen within that range.
It’s important to note that even at the ideal dosage, most people will likely not notice any beneficial effects for some time. Most research on pycnogenol has noted positive effects after several weeks of supplementation. As such, a new regimen of pycnogenol should last at least several weeks.
Pycnogenol Side Effects
Reported side effects of pycnogenol are mild when supplemented in appropriate doses, according to user reports and the above-cited studies. These symptoms may include digestive discomfort, nausea, vertigo, and headaches.
Unpleasant digestive side effects of pycnogenol are more likely on an empty stomach. Pycnogenol contains high levels of tannins, which can cause nausea on an empty stomach. (Tannins are also the primary reason drinking plain green or black tea while fasting can cause nausea.) As such, it’s best to take pycnogenol with food.
Overall, we feel that the best pycnogenol is a safe, effective way to improve your general health. It does have several short-term side effects, including headache and possible allergy symptoms. However, for the most part, users do not experience anything major. As a result of its benefits in multiple areas of human health, it’s definitely a supplement that we recommend trying out.
