Resveratrol Supplements - Stepping through the Minefield

In our last article, Resveratrol in the Media, we looked at some of the very promising media surrounding Resveratrol as an anti-aging supplement. Unfortunately, it did not take long for marketing companies to rush resveratrol supplements to market that are ineffective, deceptively marketed and in some cases dangerous.

In this article we will help you navigate the minefield of Resveratrol supplements and point you in the right direction.

Are All Resveratrol Supplements The Same?

No, no and NO! When evaluating Resveratrol supplements you need to look at ingredients, purity, dosage and deception. Let's look into each element in greater detail...

Making Sense of a Resveratrol Ingredient List


As we discussed in our article, Resveratrol Science, there are really two parts to the Resveratrol compound - Trans-Resveratrol and Cis-Resveratrol. Study after study have shown that only the Trans-Resveratrol part (technically called an Isomer) has positive health benefits. So, when you look at an ingredient list you want to make sure you see Trans-Resveratrol.

Take a look at these two labels - which one has more effective Resveratrol?

If you said Label B - You Are Correct!

Label A has 350mg of Resveratrol, but since we know that Resveratrol is made up of two parts - Trans-Resveratrol and Cis-Resveratrol - Label A only has 175mg of Trans-Resveratrol. Label B has 200mg of Trans-Resveratrol, so it is the better purchase.

What does that 99% mean before the Trans-Resveratrol? We get to that in the purity section below...


Just to make things a little more confusing - not all Trans-Resveratrol preparations are the same. Basically when a company makes a Trans-Resveratrol supplement there are different degrees of purity. You can do a 50% Trans-Resveratrol, which means if you see 200mg of 50% Trans-Resveratrol, the product has just 100mg of Trans-Resveratrol. An easy way to figure out the amount of Trans-Resveratrol in a supplement is just multiply the number that appears before Trans-Resveratrol with the amount shown in the Serving Column.

Let's look at two more sample labels...

Label B is the Pure and Better Resveratrol Supplement!

On paper it looks like Label A wins in this case. If you do the math for Label A (50% x 400mg) you end up with 200mg of Pure Trans-Resveratrol.

For Label B you end up with 198mg of Pure Trans-Resveratrol. While Label B has 2mg less Trans-Resveratrol, it is a much more pure supplement as 99% of the powder in the capsule is Trans-Resveratrol. With Label A, the capsule has 400mg, but only 200mg is pure Trans-Resveratrol - so what is in the remaining 200mg of powder?

Cis-Resveratrol and Emodin is the probable answer. We already know that Cis-Resveratrol is not effective and some studies indicate it can hamper the effectiveness of Trans-Resveratrol. Emodin is a nasty little compound that is often found in Resveratrol supplements that are less than 99% Pure Trans-Resveratrol. We could give you the science behind it, but let's just say this - Emodin is a laxative that can cause anal leakage! 99% Trans-Resveratrol contains no emodin and this is why Label B is the clear winner on purity.

Purity - Part 2

When we talk about Purity we are of course talking about the purity of the Trans-Resveratrol as discussed above, but we are also talking about the purity of the whole product.

Take a look at these two labels and guess which is more pure...

Label B is once again the winner!

In this case both labels show 99% Trans-Resveratrol at 200mg - which is great. However, if you scan down and read the "Other Ingredients" you see a bunch of things you can't pronounce in Label A. On many Resveratrol supplements you will see a number of different ingredients listed under Other Ingredients - these are all fillers and flowing agents. These ingredients make it easier and cheaper for the manufacturer to make the supplement, but have no benefit for you the consumer!

Label B represents the cleanest possible Resveratrol supplement. The only other ingredient listed is cellulose, which is what the capsules are made of. No fillers, no flowing agents, no ingredients you can't pronounce - just pure Trans-Resveratrol.


While there is still great debate on the "correct" dosage of Resveratrol to take, it is generally believed that the correct range is 100mg - 500mg per day. With the popularity of Resveratrol, you are starting to see Resveratrol show up as an ingredient in numerous supplements. Many of the supplements have just a trace of resveratrol in them, and hide the actual amount of Resveratrol present behind a blend of ingredients.

Take a look at these two labels

Label B Is The Clear Winner for a Known and Pure Amount of Resveratrol!

With Label A we have no idea how much Resveratrol is actually in the product. The "Anti-Aging" blend is 1000mg, but it may be that Resveratrol only makes up 10mg of that blend! In addition, the label does not shows Trans-Resveratrol so we worry about the purity.

We believe consumers have a right to know exactly what they are putting into their body, so we would steer clear of any supplement that just lists a number of ingredients but does NOT put the quantity of each and every ingredient.


Unfortunately there are a number of marketing companies that would try to sell ice to eskimos... and then tell the eskimos the ice was seen on Oprah and comes with a no risk free trial! We have seen it happen with Acai and we see it happening again with Resveratrol - there is a great deal of deception in the marketing of certain resveratrol supplements.

Here are some things to watch out for:

  • Claimed or Implied Endorsements from Oprah or Dr. Oz

    While Dr. Oz and Oprah have had favorable stories on Resveratrol, they NEVER ENDORSED ANY PRODUCT. Any company that would lead you to believe their product was seen on Oprah or picked by Dr. Oz is deceiving you and should be avoided. Harpo Productions has filed a lawsuit against 40 companies that were illegally using her image.

  • Free Trial Resveratrol Offers

    You have no doubt seen offers for a "free trial" of Resveratrol. The problem is these offers are not free! If you read the Terms of Service that are buried in tiny print somewhere on the website, you learn that when you enter your credit card to "just pay for shipping" you are really agreeing to let the company send you a supplement each month and bill you over $90 per month. The Resveratrol supplements are of very low quality and it is close to impossible to cancel the autoship program. Our simple advice - Do Not Buy Free Trial Resveratrol!

  • Outrageous Weight Loss and Health Claims

    We love Resveratrol and are excited about its potential health benefits, but sites that make incredible health and weight loss claims are not being honest with you. Dig deeper and you will see they do not have clinical studies to back up the outrageous claims they are making. If a site is promising their Resveratrol Supplement will cure everything - they are not being honest with you.

  • Celebrity Testimonials

    Another trick is to put photos of top celebrities all over the site and then include a line like "The Resveratrol Supplement the Stars Are Talking About". If you see that line next to a picture of Brad Pitt, you assume that means Brad Pitt is taking the supplement. Of course, this is not true - the company wants you to believe the photos on the site go with the text, but they don't. In court they will argue - "We never said Brad Pitt used it" - but they are clearly implying an endorsement by using his image and this is pure deception.

We could go on and on about deceptive Resveratrol supplement practices, but our best advice is simply read everything, ask questions and use caution before giving out your credit card.

I am confused, so what DO I want to see in a Resveratrol Supplement?

Here is our quick checklist of what you want to see on a Resveratrol Supplement:

  • 99% Trans-Resveratrol
  • Minimum of 100mg of 99% Trans-Resveratrol per serving
  • Lab Assay to show the Resveratrol was tested and is free of contaminants
  • NO emodin or Cis-Resveratrol
  • NO proprietary ingredients lists (the quantity of each ingredient should be shown)
  • NO fillers or flowing agents (Other Ingredients should just be cellulose capsule)

If you still have the energy to learn more, then we need to reveal two things...

1. Resveratrol may not be the true answer to the French Paradox
2. The X Factor is Muscadine Grapes

Why Resveratrol is Not the Whole Answer to the French Paradox?

This is our surprise ending - the big twist. If you have followed the articles, this is where you would expect us to tell you to get a pure 99% Trans-Resveratrol supplement, with nothing else in it. While a pure 99% Trans-Resveratrol supplement is a good choice, we found the ingredient that can make the formula even better - Muscadine Grapes.

We will examine the Muscadine Grapes in our next article, but first we want to explain why we believe that Resveratrol alone is not enough. The French eat and drink grapes and wine, not resveratrol. Yes, there has been impressive research on resveratrol, but there is even more research on the health benefits of grapes and wines. Grapes are filled with wonderful polyphenols and resveratrol is just one part of the grape. By isolating just resveratrol and discarding all the other healthy polyphenols from grapes, we believe you will never get the full health benefits that a full complex grape and resveratrol combination could offer.

What if there was a grape that had 6 times more Resveratrol and 40x more antioxidants than any other type of grape and still maintained the full spectrum of polyphenols that grapes have? That grape is the Muscadine Grape, the X Factor as we call it, and it is the focus of our next article...

The Story Behind Muscadine Grapes


At this point, give yourself a pat on the back - you now know more about Resveratrol than you probably ever wanted to know.
