  • Potential Side Effects: Resveratrol

    October 28, 2010: by Bill Sardi

    Derived from the medical literature and from reports by consumers to manufacturers.

    • Frontal headache: usually among menstruating females who are anemic
    • Achilles heel tendonitis: usually reported by mega-dose users of the product; believed to be related to shortage of copper; similar to Achilles tendon soreness reported with the metal-chelating antibiotic drug Cipro.
    • Melanonis coli: benign dark pigmentation of lining of digestive tract; usually discovered during colonoscopy.
    • Fatigue:  Believed to be induced by the mineral-chelating properties of the product, inducing anemia.
    • Insomnia: Believed to be due to underlying anemia.

    Symptoms believed to be related to over-inhibition of TNF (tumor necrosis factor)

    • Stiff hands
    • Skin rash
    • Anxiety reactions
    • Flu-like symptoms

    These symptoms have usually been reported by anemic individuals and are similar to those reported with the use of TNF-inhibiting drugs (etanercept – Enbrel).

    Caution: resveratrol has properties similar to grapefruit juice and enhances the effect of certain medications.  This may be beneficial or problematic.  It is best to take resveratrol pills at a different time than medications.

    Reactive hypoglycemia

    A few people have what is called reactive hypoglycemia where blood sugar can drop and induce numbness or tingling in the fingers, hands, feet or face, or experience panic attacks, irritability, nervousness, insomnia, even heart palpitations, even 2-5 hours after meals or after taking diabetic medications.  Uncommonly, some people who take resveratrol report these same symptoms, which can even occur hours after taking resveratrol.  Among individuals who are prone to reactive hypoglycemia, their blood sugar may temporarily drop a bit too far, resulting in unwelcome symptoms.  Resveratrol should be taken with food to help avoid any latent hypoglycemia that may occur, and to eat food at regular intervals throughout the day.

    Symptoms of Reactive Hypoglycemia

    • Breathlessness
    • Panic Attacks
    • Memory Problems
    • Inability to Concentrate
    • Inner Trembling and Pounding Heart 1-4 Hours after a Meal
    • Palpitations/Irregular Heartbeat
    • Weight Gain in Abdominal Area
    • Nightmares

    If you recognize any three of these symptoms in yourself over a period of time, you are probably at risk for reactive hypoglycemia.
