Resveratrol Product Buyer’s Guide (updated July 2024)

Information About Resveratrol

Resveratrol is a naturally occurring type of compound called a Polyphenol. They contain powerful antioxidant, anti-inflammatory and anti-aging properties.

Resveratrol comes in two forms:

  • Cis – less bioactive, less likely to be absorbed into the body’s cells.
  • Trans – more bioactive, higher likelihood of getting absorbed into the body.

These refer to the chemical structure of Resveratrol and affect how they are absorbed in the body. Trans-Resveratrol is the more bioactive form and therefore the superior one to use in a supplement in order to enjoy all the benefits associated with it.

The key is the source of the Resveratrol to ensure a pure and effective source of Trans-Resveratrol standardized to contain 98% purity. Japanese Knotweed (Polygonum cuspidatum) is well-known to be the preferred source of pure Trans-Resveratrol and must be derived from the rhizome root to ensure the active ingredients are harvested efficiently. In order to obtain pure Resveratrol, it must go through a purification process to isolate the Trans-Resveratrol from the rest of the plant.

Unfortunately, many manufacturers don’t spend the time or the money on the proper purification processes necessary for a pure and effective Resveratrol product. As a result, there are many Resveratrol supplements out there that don’t actually work. That is until now!

Given the right formula, from a quality manufacturer that has based their product upon scientific research and clinical data, there are supplements out there that will do exactly what they say they will with many people experiencing incredible results from a top-quality Resveratrol supplement. Our research has shown that given the correct dosage and potency of specific key ingredients – you can achieve the results that you want.

There are several key elements which make a highly effective, top-quality Resveratrol supplement. These include key ingredients such as at least 98% pure Trans-Resveratrol in a high dose, Red Wine extract for an extra boost of Polyphenols and BioPerine® to aid absorption, which have been endorsed by many scientists, medical researchers, doctors, and nutritionists. Clinical studies further support the benefits of such key ingredients with many participants experiencing positive results. These natural ingredients are shining a light and leading the way, where so many others have fallen. An effective formula can work wonders for improving your health.

Key points to consider when choosing a Resveratrol supplement

Of course, you will be dubious, so were we. Many manufacturers of health care supplements make grand promises of renewed health, only to find out a month later, that there is no real change and you are left with an empty bottle, empty purse, and empty promises. Don’t dismay – there are some that really do work – you just need to find a genuine product.

As soon as a new product hits the market, dozens of manufacturers appear, almost overnight, to try to jump on board. As a result, consumers need to be on the lookout for many products that are watered down and quite frankly ineffective, promising results that are totally unrealistic and undeliverable.

When choosing a Resveratrol supplement, you should look for a company with a strong reputation, that sells a wide range of nutritional natural dietary health supplements. An effective supplement will be formulated using high-quality ingredients that have been proven effective in clinical trials such as 98% pure Trans-Resveratrol sourced from Japanese Knotweed, Red Wine extract and BioPerine® to name but a few, which will provide the most powerful results.

If you come across a company selling Resveratrol supplements using strong marketing terms or slogans, or are endorsed by famous celebrities, you should stay clear. If the company and product formula don’t speak for themselves, then nothing else should.  

Should you decide that a natural Resveratrol supplement is for you, and you would like to try a top-quality product, check out our reviews for a number of Resveratrol products that are currently available on the market. We examined numerous products for their ingredients, consumer feedback, business reputation and much more to help you discover which supplements are the real deal! You no longer need to search Google for your answers, no more guesswork, we have done all the hard work for you.

What makes a Resveratrol supplement effective?

The secret is simply in the formula! Using the correct dosage and potency of clinically-proven key ingredients will help achieve results like nothing else. Trans-Resveratrol, the bioactive form of Resveratrol, sourced from Japanese Knotweed and purified to a high concentration of at least 98% is the most effective way to get a powerful dose delivered to your body’s cells. The addition of BioPerine® further ensures speedier absorption for better results.   

Our recommended choice stands above and beyond the competition, we think you will agree. The company’s excellent reputation, high-quality product, external independent monitoring, and testing, coupled with an incredible money-back guarantee policy, make this a formula that you are going to want to take a closer look at.

Biotivia Transmax

Biotivia Transmax claims to provide many health benefits including extending youth, improving cognitive function, helping to protect against heart conditions and managing weight. At a hefty price of $75 for a one-month supply, consumers may be expecting to find the fountain of youth in this bottle! This product is formulated using 98% Trans-Resveratrol which is the purest and most effective form of Resveratrol. It also contains BioPerine® which is clinically proven to aid absorption of Trans-Resveratrol into the body’s cells. However, the actual dose of Trans-Resveratrol is only 500mg. While this is standard for many brands, we had hoped that for $75 per month, Biotivia Transmax would have a more powerful dose. Overall though, we like this manufacturer and feel that they formulated a decent option. 

When reviewing this product, we were pleased to see that all the ingredients are pure and natural. We appreciated the fact they included ingredients to aid absorption, which is something many manufacturers overlook. Unfortunately, we felt that they were simply lacking in dosage by including half of the amount of Trans-Resveratrol that our Editor’s Choice contains. Additionally, there is no mention of the source of this formula’s Trans-Resveratrol. Both of these indicate that the efficacy of Biotivia Transmax may be lower than expected. Because of this, we would have hoped to see an extra boost of Polyphenols, but that too was lacking. 

Interestingly, when we perused customer reviews, we found a recurring complaint about a timed-release formula of Biotivia Transmax which is no longer available to purchase. Customers seemed to have been pleased with that product and found the current product unsatisfactory and not worthy of its exorbitant price tag. We had expected to see a strong money-back guarantee based on the product’s cost but what we found was a return policy that expires after 30 days. Biotivia could have definitely improved the kind of guarantee they provide but we realize that a good guarantee usually comes with a manufacturer’s confidence in the results you will experience so that could explain why. Furthermore, we were also discouraged to see that they have an autoship option as it can be very difficult for customers to disentangle themselves from that commitment.

Reserveage Nutrition Resveratrol

Reserveage Nutrition Resveratrol claims activate the ‘longevity gene’, promote heart health and defy aging. This formula contains 500mg Trans-Resveratrol and has a 4-hour sustained release. The Trans-Resveratrol here was derived from Japanese Knotweed, which is the preferred source for Resveratrol. However, we did not find any ingredient to aid the absorption of Trans-Resveratrol into the body. More concerning, this formula contains a proprietary blend.  

A proprietary blend will sound impressive to the average consumer. Indeed, the proprietary blend included here is called Pro-Longevity Factors Blend. Additionally, this manufacturer boasts that it contains Triactiv Technology. But what do these words mean? Nothing! These are not backed by clinical studies or scientific research. What they are, are made up scientific-sounding words by the manufacturer to lure in consumers. It is more important for manufacturers to be completely transparent on their labels and include a breakdown of ingredients with their doses. This is something that can be hidden in a proprietary blend. 

When we analyzed customer reviews we found many consumers were put off by how pricey this product is. While there are those who recommend this product, many others found similar products, without proprietary blends, that delivered the same results. Many times what will work for one person, will not work for another. This is why we recommend finding Resveratrol supplements with a money-back guarantee. Unfortunately, there was no mention of any such guarantee here. Ultimately, the decision to purchase is a personal choice that each consumer has to make for themselves.
