Kenya, preparing for the great migration
Dear reader,
Some 20 years ago Resveratrol was the supplement to take. It was heavily promoted by longevity experts like Dr Sinclair. Resveratrol was also found naturally in wine. As a result, wine lovers jumped on the band wagon. More wine, for health benefits only of course.
To obtain a dose of Resveratrol that might have health benefits, one would need about 100 mg per day. This would require drinking approximately 100 to 1,000 glasses of red wine per day. I do not know about you, but drinking 100 glasses of red wine does not go hand in hand with longevity. This is true even for former diplomats.
In the end I decided for Pterostilbene and I stopped taking Resveratrol.
1.My thoughts about supplements in general
Before delving into the details of Resveratrol, let me first outline my general approach of this health project99+. The five key factors for longevity are: (1) diet, (2) stress management, (3) quality of sleep, (4) exercises and strength training, and (5) an active social life.
By excelling in these five areas, you significantly increase your chances for a longer and healthier life. Supplements are the sixth category and, in my opinion, offer the most intriguing avenue for intervention.
Supplements provide hope—hope for a much longer life. Many studies are underway, and life is too short to wait for the results of all of them. Promising findings are emerging at an increasing pace, thanks in part to advancements in AI. I am among those open to taking certain supplements, even though their claimed effects are not yet scientifically proven. I adhere to the “do no harm” principle and choose to give them a try.
2.What can Resveratrol do? At first sight a lot.
Resveratrol is a natural polyphenol (see note below this blog on polyphenols). It has been detected in more than 70 plant species. It is especially found in grapes’ skin and seeds. It acts against pathogens (stuff that can make you ill), including bacteria and fungi.
Many studies have demonstrated that Resveratrol possesses a very high antioxidant potential. It has other bioactive effects, like anti-inflammatory, anticarcinogenic (cancer), cardioprotective, vasorelaxant, phytoestrogenic and neuroprotective.
Longevity experts have been interested in Resveratrol since the early 2000s. Their interest increased particularly following research that suggested its potential role in promoting health and longevity. One study found that Resveratrol could trigger sirtuins. Sirtuins are proteins that are believed to play a crucial role in aging and metabolic regulation. Resveratrol was also linked to calorie restriction, an intervention that has been linked to increased lifespan.
3. One big problem with Resveratrol
Its half-time is low (max a few hours, some studies talk about 15 minutes) and its bioavailability is very limited. Some talk about a few percentages only, others about a maximum of 20%. This means that your body processes most of the supplement before it can do its work. The remainder that works lasts a very short time only. Very disappointing. This covers a wider theme that one should always consider when taking supplements. Omega-3 fatty acids last three days and most of the intake is being used.
4.Pterostilbene comes to the rescue/what is Pterostilbene?
Pterostilbene is a natural substance found in small quantities in vegetables and fruits such as blueberries. Those quantities, however, are so small. You need to take supplements for it to have an effect. Pterostilbene is chemically similar to Resveratrol. Both are compounds known as stilbenes. It is rapidly emerging as a supplement to watch.
5. Differences between Resveratrol and Pterostilbene
Pterostilbene is considerably better absorbed by the gut compared to resveratrol. Pterostilbene has a bioavailability of about 80 percent, compared to 20 percent for Resveratrol. Some studies suggest that the bioavailability of Resveratrol may be even as low as 1-3%.
Pterostilbene also has a longer half-life, which may allow it to be effective at lower doses. Around 2 hours for Pterostilbene and 15 minutes up to one hour for Resveratrol.
Studies have already reported that Pterostilbene can be superior to Resveratrol for certain health conditions. It has shown promise for improving cardiovascular health. Pterostilbene may also enhance glucose levels and cognitive function. One minus is that there are far fewer studies on Pterostilbene than on Resveratrol.
6. Pterostilbene and Longevity/What does Pterostilbene do? A lot
Many studies demonstrate beneficial effects of pterostilbene on health and the aging process. The benefits of pterostilbene are promising, and supplements are likely safe for most people. Still, much more research has to be done. Results with mice is one step, with humans another.
- Pterostilbene reduces inflammation and improves DNA repair. It activates sirtuins which are enzymes that repair DNA and improve metabolism. These enzymes can extend health span and lifespan.
- Pterostilbene is also an autophagy inducer. Autophagy is the process that clears up cellular waste that accumulates in the cells. During aging, autophagy is reduced. Pterostilbene can also trigger AMPK. AMPK is an important energy sensor in the cells. This activation, in turn, inhibits mTOR, a strong inhibitor of autophagy.
- Pterostilbene increases the production of powerful antioxidant enzymes, protecting the cells against oxidative damage. Pterostilbene can improve brain functioning and can protect the brain.
- Pterostilbene has also been shown to increase levels of other antioxidants. These antioxidants are linked to everything from improved detoxification to reduced oxidative stress in mitochondria. Mitochondria are the energy powerhouses of our cells. They play a role in most age-related diseases. They also make sure you have enough energy to function optimally.2. It may help fight or prevent cancer.
- Several animal studies have found that supplementing with pterostilbene lowers blood glucose levels. This suggests that this antioxidant may play a role in protecting against diabetes. It may also improve insulin sensitivity.
- Some evidence even suggests that Pterostilbene and Resveratrol may mimic the effects of calorie restriction. This practice has been shown to increase life span and help prevent age-related disorders.
7. Side Effects of Pterostilbene
Both can on rare occasions have some side-effects. They vary from gastrointestinal symptoms and headaches to fatigue. Rare interactions can occur with some medicines, like blood thinners or medications that are metabolized by the liver. Various studies show that Pterostilbene improves many other biomarkers of cardiovascular health, including lowering blood pressure. This could be problematic for people with already low blood pressure or those on antihypertensive medications.
A recent study suggests a small but significant increase in cholesterol. This change may occur at the normal dose of 100 mg of Pterostilbene. This effect is observed at least for people with a higher-than-normal BMI. But as mentioned before, more studies are necessary. Conducting human trials with all the variables is quite difficult.
8. My experience
After finding out more about Resveratrol I decided to swap it for Pterostilbene. I take several other supplements, so it is difficult to say if and how it works. I find the studies convincing. I never experienced any side effects. A question I want to explore further is how to have the positive influence of Pterostilbene the whole day. Its half-life is 2 hours. This implies that it only works 4 hours per day if you take two per day.
Some experts also believe that pterostilbene and resveratrol are better when consumed together. They act synergistically to promote health and prevent a variety of diseases. This is why you’ll often find them packaged together in supplements. I have not seen much about this, so I only take Pterostilbene.
Enjoy your life, think about the big 5, do not forget your pills,

Note: you often read about “polyphenols”. This is a large and diverse group of 8000 compounds with potential health benefits. They occur as compounds in plants and are known for their antioxidant properties and potential health benefits. They do not directly influence the plant’s growth, development, or reproduction. However, they play important roles in protecting plants from ultraviolet radiation, pathogens, and herbivores.
Note. However, as with many compounds, the exact half-life can vary based on factors such as the dosage, individual metabolism, and form of pterostilbene (e.g., whether it is taken as a supplement or comes from food sources). Additionally, pterostilbene is reported to have improved bioavailability compared to resveratrol, which may influence its effects in the body.
