Isotonix OPC-3 Antioxidant Supplement - with Pycnogenol, Grape Seed, Bilberry, Red Wine & Pine Bark Extracts (90 Servings, 300g)

The first thing is that I think everyone knows that Isotonix is one of the greatest products we've ever developed. However, I'm disappointed with the new the bottle. I like the new look of the bottle and the label. But the cap is a real issue with my customers. The cap holds enough water for one serving however when you fill it to the top to get the correct water amount and they try to stir their isotonix or other products, the three tabs in the bottom of the cap that is used to snap the cap onto bottle gets in the way of stirring the product. Also filling the cap with the correct amount of water in the cap they wind up spilling the product. So they're using the old cap instead. Maybe we need to rethink the design.

Since adding OPC-3 to my day, I feel like I have more natural energy to get through my busy schedule. I've also noticed that my body feels less stiff and more comfortable after workouts and long days, which has made a positive impact on my overall wellness.<p>I appreciate knowing I'm supporting my health with a high-quality antioxidant supplement that fits easily into my lifestyle

The product is and has always been exceptional,I take it every day and each day I feel better. The only complaint I have is when I made my order I tried to sign up for auto shipping but the system would only allow auto shipping if I doubled my first order . I did not appreciate that. I will continue to use the OPC-3 even though it cost more but you may want to fix that double pay thing.

I felt the energy from the first time I took it. I like the fact that you only need to wait 5 minutes before eating or drinking anything else. It absorbs quickly, and gives me a feeling of well being and elevated energy levels.

Carla and Keith Jackson introduced me to the product. I love love the benefits I recieved from using this product! It's great. My job has me on my feet the whole time and my energy is sky high now.

I have been taking OPC-3 for many years and I would not go without it. So the product is 5 stars, as many issues I used to deal with are gone - BUT the new cap is not at all good for measuring the water - you can hardly see the line for the 1 serving measurement. What was wrong with the previous caps? I agree with others who have the same issue. I'm saving my old caps, please bring them back! I also like the old label coloring on the bottles better than the new, as it was easier to differentiate the products. Why mess with a good thing?

My husband (before he passed away at 92 1/2 years) and me now have been taking Isotonix products for 3 decades+ and love the quality. However, the new packaging with the pretty white cap is nice looking but not practical for measuring water. The clear caps with a line on them were PERFECT. Now a new person needs to find a measuring cup to measure the water correctly. Having the clear plastic cups with the bottles was so much more practical and easier for traveling. I would like to know WHY the measuring cup was discontinued. The only reason I can think of is cosmetic. Please return the clear measuring caps to the isotonix bottles!!! It's a shame to have such a wonderful product with no measuring caps. Product=5 stars; new caps=1 star.

Several of your customers (reviews titled "OPC3" 8/27/25, "Good Product, Bad Redesign of Bottles" 7/1/25, "HATE the new caps" 6/26/25, "Bring back the old see-through cap!", etc.), including me, are telling you that the new WHITE CAP on the OPC-3 bottle is too DIFFICULT to read the 2 OZ. MARKING inside of it. We DON'T MIX in the cap. We simply want to read the 2 oz. marking that is inside the cap in order TO MEASURE THE WATER. Your Customer Service responses are not responding to what we are telling you. .. Please make the cap's 2 oz. water level marking easier to see.

I purchased this product because it was recommended by a trusted source. Upon opening it and tasting it I noticed a very fake flavor. I then read the ingredients and was horrified to see that it contains the most gut, disturbing ingredient, known to mankind, maltodextrin. The other ingredients are fructose, glucose, citric acid, silica and modified food starch. I contacted a person at the company about getting a refund only to be told the ingredients are premium non-gmo products. <p>Do not buy from Isotonix because their profit is more important than your health

I love the product itself, but hate the new caps. If you don't place the new caps on just right, the bottle falls when you pick it up. More importantly, the old caps were a measuring cup for the product. It was convenient for several reasons. I am disabled, and if I had to leave the house and take my vitamins & OPC3 with me, it was easy to measure out what I needed instead of trying to find a measuring cup if I was in the hospital or at someone else's house if I needed help.
