The Power of Isotonic Formulas Compared to Tablets

In 2009 a group of researchers in Italy conducted a study to see if an isotonic formula of a known highly effective Tablets vs liquidsantioxidant behaved differently on the body compared to the same antioxidant in tablet form.

Isotonix OPC-3® is a powdered antioxidant blend that when mixed with the appropriate amount of water becomes “isotonic“.  Isotonic means “same concentration” and is an ideal ratio between solid and liquids that our bodies convert what we ingest into before it can pass into the small intestine.

The four hour test compared Isotonix OPC-3® in a tablet form to Isotonix OPC-3® in its standard isotonic form.  The amount of water that was consumed with the tablet was equal to the amount of water used in the isotonic version.

Results of the test were startling. Levels of free radicals were measured in the blood plasma of test subjects.  The isotonic OPC-3® reduced free radicals six times more in just 10 minutes compared to the tablet version. The tablet form did eventually reduce free radicals substantially as well, but seriously lagged behind the isotonic form thorough out the four hour test .

Researchers concluded that “the findings demonstrate that the flavonoid mixture provided in isotonic OPC-3® is significantly more bio-available in humans, in terms of antioxidant activity than an equivalent mixture in tablet form.”  Overall the isotonic OPC-3® formulation resulted in a stronger antioxidative effect than an equivalent tablet form.

The results of this test highlight the importance of leveraging the advantage of isotonic formulas for established nutritional supplements like: Isotonix® Coenzyme Q10, Isotonix® Resveratrol, ORAC formulas, Isotonix® Vitamin D with K2, Isotonix® Calcium Plus, B Complex, Vitamin C, Acai, Probiotics, Isotonix® OPC-3 Beauty Blend, Multivitamins, Isotonix® Prenatal Multivitamin, Children’s vitamins, Digestive Enzymes, L-Tryptophan, Blood SugarVision formulas, Anti-aging and Joint Health Formulas. Reducing the amount of work the body needs to do in order to receive the nutritional benefits of these products provides significant “bottom line” results.

    I was very glad to find this report when I looked for a simple explanation of the power of isotonicity. Many people want to know why OPC-3 is different and I think this says why. Thank you, Robertalovered

    Hi Brian,

    Thank you for your interest in Isotonix OPC-3! I apologize if some of the imbedded links in my posts were difficult to see. CLICK HERE to be taken directly to an order page for OPC-3.

    OPC-3 comes in two sizes (30 servings for $29.95 or 90 servings for $69.95) and is readily available with several shipping options to choose from. Once you choose a size, make sure you put a quantity in the cart.

    The font size that WordPress defaults to is pretty small. However, the size that appears on your computer screen can be increased by holding down the control key and pressing the plus symbol (+) on your keyboard. That should make it much easier to read.

    I hope that helps! Let me know if you have any other questions.
