Resveratrol is an antioxidant phytonutrient that occurs naturally in grapes and red wine and which supports healthy metabolism and optimal blood flow.* However, resveratrol doesn’t usually stay in the bloodstream very long, so its benefits may be limited. Resveratrol-SR™ features MicroActive® Resveratrol, which delivers resveratrol in a special micronized, sustained-release matrix to increase its bioavailability.

  • Delivers sustained release over 12 hours.

  • Released slowly over time so blood levels stay consistently elevated.

  • Achieves higher blood levels over a longer time.

  • Consistently elevated blood levels lead to more resveratrol for the body
    to use.

  • More bioavailable than regular resveratrol.

Resveratrol is a phytonutrient and antioxidant that naturally occurs in grapes and red wine. Human clinical studies have shown that resveratrol supports healthy metabolism and optimal blood flow – all of which have cardiovascular, brain, and anti-aging benefits.* Microactive® Resveratrol delivers resveratrol in a special micronized, sustained-release matrix. Not only does MicroActive® Resveratrol have 2.5x better bioavailability than regular resveratrol, but the resveratrol is also released over 12 hours. That means it stays in the blood longer – and is therefore active longer – than regular resveratrol.


Q: How long does the Resveratrol stay in your system?

A: The MicroActive Resveratrol in our Resveratrol-SR formula has been shown to offer 12 hours of sustained release and offers 2.5x greater bioavailability than regular resveratrol.

Q: Is it possible for the polymers in the formula to bio accumulate over time?

A: The polymers like HPMC are not absorbed by the system. HPMC is a soluble fiber that is also not fermentable by the colon bacteria. Beta cyclodextrin  is also not absorbed from the stomach and small intestines. It can be broken down by the enzyme amylase to form open chain sugars and glucose. Carnuaba wax is highly insoluble and is not absorbed. So, all the polymers are eliminated from the GI tract, no chance of bioaccumulation.

Resveratrol -SR

I love this product. I typically open my capsules and pour the contents onto a spoon and take it that way, so I especially like that your resveratrol is palatable and does not upset my stomach. I just wish you sold a 60-capsule size bottle.

The Best Brand

After doing extensive research and consulting with an MD and a Naturopath, I believe this is the highest quality and most bioavailable Resveratrol product I am aware of!

Barb Z.

I was very pleased with the product. It is very nice to have something come in a glass bottle and not in plastic. The shipment was here very fast. I ordered lots of different supplements from different suppliers, and this one was the very first to arrive. The others are not here yet. Thanks!

I purchase my supplements thru Quality of Life because I know that I'm actually taking a product that has high quality ingredients that will benefit my health. I know you can find cheaper products, but I feel confident that Quality of Life products are giving my body only the supplements without all the added fillers you find in alot of supplements today. Thank you for your great products.

High Quality Product

I have tried several Resveratrol products, but have found this one works the best for me. I'm impressed with the quality of this product.

Using but it sure of results

Just started using .. not sure of results yet.. energy seems to be better

CAUTION: Product Makes Me Sick and I Can Tolerate Most Herbals!

My body is tolerant to almost every kind of herbal supplement. However, there's something in this Resveratrol Time Release that really makes me sick, bad headaches, weakness, nausea. I tried it a dozen times, it just doesn't digest well or something. I would urge CAUTION before trying this product. Once you buy it, you're stuck with it. They won't take it back. Save your money and get a BETTER QUALITY product!


Its great does what it says

Excellent Product

Excellent product with exceptional quality and value. So much better than what you usually find in health food stores.
