Frequently asked Questions

What makes Isotonix OPC-3 special?
Isotonix OPC-3 contains bioflavonoids, plant compounds that support cardiovascular health, healthy circulation and skin, joint and tissue integrity; it uses a unique Isotonix delivery system for fast, effective absorption and includes scientifically proven antioxidants to fight free radicals, making it one of the most powerful products available.
How quickly does Isotonix OPC-3 work?
Thanks to its liquid, isotonic form, Isotonix OPC-3 is absorbed quickly by the small intestine, entering the bloodstream within minutes; this rapid absorption allows the body to benefit almost immediately.
Why should everyone take Isotonix OPC-3?
Free radicals cause oxidative stress, which contributes to aging, circulation and heart and immune health. OPCs are powerful antioxidants — with more staying power than vitamins C and E — that help neutralize free radicals. Taking OPC-3 daily is essential for combating free radical damage and promoting health.
Why should healthy or athletic people use Isotonix OPC-3?
Even athletes experience free radical damage from increased oxygen use during exercise, which can affect muscle performance and endurance. Studies show OPCs promote endurance, reduce mild muscle cramps and support healthy blood flow, helping muscles recover and perform.
Does OPC-3 benefit people who menstruate?
Yes, studies show OPCs can help menstrual cramps.
What is Pycnogenol®?
Pycnogenol® is a patented extract from French maritime pine bark, supported by over 120 clinical studies; it acts as a powerful antioxidant, helping maintain healthy circulation, blood pressure and blood vessel function by promoting nitric oxide production.
Is Isotonix OPC-3 suitable for children?
Yes! The new Isotonix OPC-3 label now indicates it is for children ages 4 and over, making it easy to add to a family-friendly wellness routine. To prepare, simply pour 1 small capful (3.3 g) of Isotonix OPC-3 powder into a cup, add 3 fl. oz. of water, and mix. One to three servings may be taken daily, or as directed by your or your child’s health care provider. It’s a simple, convenient way to make daily wellness a little easier for the whole family!
