Drink powder 300g or 90 servings: each serving (3.33g Powder) contains 90mg OPC extracts as compared with Isotonix OPC-3 of only 75mg
Our French pine bark extract ingredient costs about $2000/kg for the highest quality (very concentrated OPC oligomers), while Chinese pine bark extract used in other products costs $100-200 due to low quality (very little OPC in it).
