Pycnogenol® Benefits

Pycnogenol® French Maritime Pine Bark Extract has a rich history of clinical research, making it one of the most extensively studied nutritional supplements for promoting overall health and well-being. Its benefits include:

Heart, Circulatory, & Arterial Health

Pycnogenol® supports endothelial and arterial health by helping to inhibit inflammatory factors called cytokines. It encourages healthy nitric oxide levels in the arteries, which support endothelial function and arterial blood flow. Pycnogenol® also promotes a healthy inflammatory response and platelet function.

Skin Care & Collagen Support

Pycnogenol® has been proven to stimulate collagen synthesis and enhance skin elasticity while reducing skin fatigue. With 20 clinical investigations into skin care alone, Pycnogenol® has demonstrated the ability to elevate hyaluronic acid production and moisturize the skin. It also protects against photo-aging, reduces pigmentation, and inhibits the breakdown of collagen and elastin to maintain healthy skin.

Antioxidant & Blood Sugar Support

Pycnogenol® helps maintain healthy glucose levels and boosts the body’s antioxidant defenses with its powerful phytonutrient compounds. It inhibits free-radical activity that can be damaging to cells, tissue, organs, and DNA. Additionally, it inhibits stress on delicate vascular walls and supports healthy circulation.

Brain Health, Cognition, & Memory

Pycnogenol® has been found to improve cognitive function and enhance numerical and spatial working memory. It also improves memory and test scores in college students and reduces test anxiety by 17%.

Respiratory, Allergy, & Immune Health

Pycnogenol® helps combat inflammation and normalize immune response by lowering the activity of nuclear factor-kappa B (NF-ĸB), the immune cell that triggers inflammation. It protects the body from the sniffles and sneezes by promoting a healthy response to histamine and inhibiting the release of histamine from irritated mast cells.

Vision & Eye Health

Pycnogenol® acts as a potent free-radical scavenger and protects retinal lipids. It strengthens and protects retinal capillaries, enhances endothelial function of the retinal microvessels, and supports micro-circulation in the retina.

Men’s Health

Pycnogenol® significantly improves erectile function by 45 percent and supports healthy arterial relaxation. It may also counteract benign prostate enlargement and help facilitate emptying of the bladder after 60 days of supplementation. Additionally, Pycnogenol® helps stabilize muscles through the natural aging process, supporting muscular function and endurance.

Women’s Health

Pycnogenol® helps reduce abdominal discomfort and cramping in women experiencing difficult menstrual periods by 80 percent and cramping by 77 percent. It decreases tenderness during menstruation after just one month of supplementation and provides further relief after the second month. It also reduces hot flashes, fluctuations in mood, panic attacks, and other common manifestations associated with women entering the menopause transition.

Sports Nutrition

Pycnogenol® supports an active lifestyle by protecting muscles from harm during activity, enhancing performance and endurance, speeding up recovery, and getting you back in action faster.

In summary, Pycnogenol® is a powerful nutritional supplement that provides a wide range of benefits for overall health and well-being. With its proven track record of clinical research, it is a safe and effective choice for anyone looking look and feel their best.
