Resveratrol: The Truth

Resveratrol | Red Wine

At one time, the fact that the French could eat extremely rich, high-fat meals on a regular basis without suffering from the same levels of heart disease as the rest of the world was a mystery. It was such a mystery that it was named the French Paradox. The only significant difference was the people of France loved their local wines and enjoyed a glass or two with every meal.

Suddenly, everyone was eager to add wine to their diet. Some felt that it was the alcohol itself, while others thought it might be the stress relief that could come with a small drink or two. Other forms of alcohol in moderation provided small benefits, but nothing could compare to red wine. Soon, researchers discovered the chemical in red wine that was responsible, Resveratrol. Let’s take a closer look at this healthy, all-natural substance:

The Health Benefits of Resveratrol
Resveratrol’s biggest claim to fame is that it can reduce the levels of bad cholesterol in our blood stream to prevent heart disease. It also improves circulation, modulates blood pressure, and protects blood vessels. As if this wasn’t enough, Resveratrol acts as a strong antioxidant to prevent cancer. Studies in rats have shown that mega-doses of this miracle chemical can even destroy a large amount of tumor cells.

Resveratrol has been thought of as the fountain of youth by some. Although the jury is out on that one, it has been shown to be helpful as a weight loss aid. It is thought to activate the SIRT1 gene during low-calorie diets to burn fat instead of allowing the body to go into a starvation mode where it desperately hangs onto every bit of extra weight. This gene is also thought to be the key to prevent aging.

Even if Resveratrol can’t help us look younger, it can definitely help us feel that way. It prevents or slows the progression of  many age-related diseases including Alzheimer’s, gout, and inflammatory diseases. Many reports say that this red-wine component can even help with hair loss and increase energy levels.

The Problem with Supplements
Many people were interested in adding Resveratrol to their diet, but they weren’t so thrilled with drinking red wine with every meal. For most Americans, consuming enough of this healthy chemical through wine alone wouldn’t fit into their lifestyle. Most jobs nowadays frown on even a single glass at lunchtime.

Soon, the diet industry responded with Resveratrol supplements in both liquid and pill form. However, many were just marketing gimmicks that didn’t supply nearly enough active ingredients to reach therapeutic levels.  Many supplement products provide a daily dose of 200-600 mcg per day.  This is significantly less than 500mg-2000mg shown to be effective in various clinical studies.  Unfortunately these substantially higher dosages of Resveratrol would be equivalent to hundreds of glasses of wine per day.

Something else to consider is that low-quality Resveratrol tablets are only about 50% pure. This would mean that a 100 mg pill only contains about 50 mg of Resveratrol with the remaining 50 mg taken up by other ingredients including emodin, a substance responsible for side effects like upset stomach and a variety of other digestive symptoms. When possible, only purchase supplements labeled as 99% pure trans-Resveratrol.

In addition to purity, the absorption rate is critical. After all, you can take pill after pill, but they will have little affect on your health if your body can’t absorb the Resveratrol. For the best bio-availability, choose supplements that are manufactured with a micronization process that has already broken down this chemical into small units for easier digestion. This is the reason that so many people rely on liquid supplements as opposed to the tablet form. Although it’s much easier to pop a pill than to drink a glass or more of Resveratrol in liquid form, the bio-availability is much better with the supplemental drinks.

Resveratrol | Red GrapesOther Food Sources of Resveratrol
Of course, it’s always best to get critical nutrients from your diet. In most cases, our body’s digestive system breaks down vitamins, minerals, and other essential nutrients better when they’re delivered through food sources. Over 70 plant-based foods contain Resveratrol including grapes, blueberries, peanuts, and Japanese knotweed. If you plan on adding grapes to your diet, the muscadine variety has the highest levels. Also, Japanese knotweed is so high in Resveratrol that this exotic herb is rapidly hitting the Western supplement market.
