Frequently Asked Questions
What sets Isotonix™ OPC-3 apart from other bioflavonoid products?
Isotonix OPC-3 offers scientifically supported OPCs, found to be the most powerful antioxidants for human health. In addition to being powerful antioxidants, these individual OPCs have been shown to provide a myriad of specific health benefits. This science-driven selection of OPCs is unique to OPC-3, as is the Isotonix delivery system, which enables rapid and highly efficient absorption of the OPCs. The potent nutrients, in combination with the highly effective delivery system, makes OPC-3 the most powerful free radical scavenging product available.
Why should everyone take Isotonix OPC-3?
Everyone is subject to free radical damage and oxidative stress. Free radicals develop as byproducts of physiological processes that occur within the body. This damage does not cause noticeable harm at first, yet may add up over the years. This process is largely responsible for the aging process. Free radicals have been linked directly to premature ageing, poor circulation, poor heart health and poor immune health. OPCs are the most powerful natural free radical neutralizers and you get the best of all OPCs by taking Isotonix OPC-3. Regular use every day is vital for keeping free radicals in check and a long, healthy life. Laboratory studies have shown that OPCs are more powerful antioxidants than vitamin C and vitamin E.
How long does it take to benefit from Isotonix OPC-3?
OPC-3 not only provides the most potent OPCs available, but the unique Isotonix delivery system also ensures that the small intestine rapidly absorbs the OPCs, which are available in the blood stream within minutes. This is because the OPCs are delivered in liquid form. The liquid is isotonic, which means it duplicates the environment in our cells and blood stream in terms of pH, electrolytes, etc. This enables the OPCs to enter the body easily and with a high level of bioavailability. Because of the rapid absorbability, the body should benefit from Isotonix OPC-3 almost immediately.
I am healthy and athletic, why should I take Isotonix OPC-3?
Everyone is vulnerable to the ageing process caused by continuous free radical damage. Athletes tend to be exposed to elevated levels of oxidative stress. Free radicals develop as byproducts during metabolism when calories are processed with oxygen. Athletes inhale 10–20 times more oxygen during physical activity over rest periods. The increase in activity creates additional free radicals. In fact, these free radicals are known to limit performance, as free radicals appear to take their toll on muscle tissue. Studies on recreational athletes have shown a 20% endurance increase with OPCs, as compared to a control group receiving a placebo. Another study has shown that athletes using OPCs suffered significantly less muscle cramping during and after performing. Isotonix OPC-3 helps to maintain healthy blood flow and this supports oxygen supply to muscles.
Does OPC-3 have a rejuvenating effect?
The damage caused by free radicals adds up with time. A cause for more worry is the fact that your body's own mechanisms to keep free radicals in check decline with increasing age — when you need them the most. Suddenly, we find ourselves confronted with some typical age-related problems. Some cells of our body are more vulnerable to free radicals than others. OPC-3 has the ability to go in and do a knockout job, cleaning and scavenging the free radicals that feast on cellular energy, and take it away from vital processes.
What exactly is Pycnogenol®?
Pycnogenol is the registered trademark of Horphag Research (UK) Ltd. for a standardized extract of bark of the French maritime pine tree. Pycnogenol is particularly renowned for its extensive clinical research with more than 120 studies published in peer-reviewed medical journals. The flavonoids in Pycnogenol not only act as powerful antioxidants, but they also appear to promote the normal generation of nitric oxide (NO). NO plays a key role in regulating cardiovascular health. Nitric oxide promotes the normal relaxation of arteries, supports normal diameter of blood vessels and supports helps maintain healthy blood pressure and circulation. NO promotes normal platelet activity allowing the blood to maintain a normal, fluid viscosity. Pycnogenol has been awarded various patents for its ability to support healthy platelet activity.
