    Introduction

    What is Pine Bark Extract?

        The pine bark extract group had a significant reduction in hyperactivity and improved attention, visual-motor coordination, and concentration, whereas there were no positive effects noted in the placebo group. One month after pine bark extract treatment ceased, patients had recurrence of symptoms. Treatment was not significantly effective for girls in contrast to boys, but there were only 6 girls in the pine bark extract group.

     

       An extract of pine bark has proven to be one of the most potent antioxidants, a property that may explain why pine bark has been used in folk medicine around the world, according to a new report by scientists at the University of California, Berkeley.

    Main function:

    1. Extending the lifetime of vitamin C in the body, prolonging its beneficial effects as an antioxidant.
    2. Helping Vitamin C work better in the brain. Vitamin C is needed for the synthesis of the neurotransmitters norepinephirine, dopamine and serotonin, which are involved with ADD.
    3. Suppressing the production of NO (nitric oxide) and thus limits the collateral damage resulting from immune system attacks on viral and bacterial invaders. Excess NO has been linked to inflammation, rheumatoid arthritis and Alzheimer's disease.
    4. Preventing and treating a condition known as chronic venous insufficiency
    5. Being effective for slowing retinopathy
    6. Lowering blood levels of LDL ("bad") cholesterol moderately
    7. Relieving abdominal pain for women with endometriosis.
    8. Improving concentration and reducing restless behavior for the children with attention deficit hyperactivity disorder (ADHD)
    9. Injecting pine bark extract produced significant reductions in blood sugar levels. taking orally pine bark extract has also shown slight antidiabetic effects.
    10. Fighting aging and restoring wrinkled skin
