Based upon the studies I've read that suggest resveratrol can have positive effects on longevity, eyesight, and weight, I went ahead and grabbed a bottle. What could it hurt? (Well, technically, most of the studies have been done on animals, and the long term effects aren't known, so it could hurt a lot of things... but that wasn't sufficient to deter me.)For the past two weeks I've been moderately restricting my calorie intake, and tracking my calories, water intake, exercise (mostly walking and body weight exercises), and various other things. Based upon the "calories in/calories out" model (taking in fewer calories than you burn through exercise and basal metabolic processes), I should be losing about 1.79 pounds a week (at 3500 calories per pound.) Instead, I've been losing 5 pounds a week.I'm not sure whether I should give credit to resveratrol, or resveratrol alone, but something is causing me to lose weight more than twice as fast as anticipated.I've also increased my intake of dark leafy greens and water, and have committed myself to walking about an hour a day, so it may or may not be the resveratrol that's having the effect I'm witnessing. It could be any number of factors, or a combination of them.Preliminary research on rats shows that reservatrol increases lipolysis (breakdown of fats) and decreases lipogenesis (storage of energy as fat), so I could be witnessing those effects. And even if it's coincidental, I see no immediate reason to stop taking this supplement.If you track your calorie input and output, and take a resveratrol supplement, I'd love for you to leave a comment about how changes in your weight compare to what's expected on a simple calories in/calories out model. It provides a good baseline of comparison, and perhaps we'll be able to see if resveratrol is the culprit. And informal scientific study, if you will.(((basal metabolic rate x 7) - calories consumed in a week) + calories burned through exercise in a week) / 3500 calories per pound = expected weight loss per week((14,518 - 11,900) + 3656) / 3500 = 1.79 pounds per week (expected)Starting weight (9/10/2012): 220Current weight (9/24/2012): 210(220 - 210) / 2 weeks = 5 pounds per week (actual)Search for a BMR calculator to get your basal metabolic rate (the number of calories you'd burn if you sat around and did absolutely nothing). Multiply that value by 7 to get how many calories you'd burn in a week. Subtract the number of calories you consume in a week from that. If the result is positive, you're fewer calories than you'd burn by just sitting around, if it's positive, you're eating more calories than you'd burn by just sitting around. Add that to the number of calories you burn in a week and divide everything by 3500 (calories in a pound of fat). The result is how many calories you should be expected to burn in a week. If it's negative, that means you should be gaining weight.

Just to answer a few questions that have come up about Resveratrol. I am a biological researcher, but not an MD yet, so don't take the following as medical advice in any way, shape, or form. I merely try to summarize scientific literature on the topic to date (April 22nd, 2013).*How can this help me?Here is the story behind Resveratrol. Your cells are always dividing- replacing old or damaged cells. For instance, when you scrape your knees, new cells need to move in and divide to fill the gap. Now, every time one of those divisions takes place, the DNA inside the cell replicates as well. With each of those replications, the DNA's ends shorten (the ends of chromosomes are called telomeres). After a set number of divisions, these ends get too short and the cell will no longer be able to divide. The cell dies. If you imagine this happening to every cell in your body at some point in time, you will see why people get old as they lose more and more cells.Resveratrol comes in, and indirectly, activates a protein called telomerase. Telomerase lengthens those ends, and theoretically makes your cells live longer.*How much do I need to live longer?You need to understand the story above to understand this answer. Studies in yeast, flies, and mice have shown that Resveratrol in somewhat very large quantities increases the life span of these organisms. Sometimes, the life span extension can be dramatic (50%!), but very modest in others (~10% or less). Generally, if we were to generalize mice studies (since they are the closest to us genetically; we share 90% of our genes with them!), you'd need about 2 grams to get the same results. BUT continue reading below.*So should I take 2 grams then?Absolutely not! There have been very few studies in humans, and it's hard to tell what would happen to humans with consistently high doses.There might some dangers, too. Recall that we lengthen the cell life span beyond what is natural with Resveratrol. This happens to be what cancer does, too. It stops cells from dying naturally when they should, and they divide beyond control.So there is balancing act between cell death and cancer (evolution tells us this might be the reason we age; to stop cancer before it gets to us). You probably don't want to mess with that equilibrium too much.*Are there natural ways to lengthen life span then?As it happens, there are. The same genes that Resveratrol activates are activated by caloric restriction (aka not stuffing your face in those delicious cupcakes). Exercise also helps.*What is the conclusion?There are no free lunches, and you should always be careful with these supplements. There is no reason to believe there is any danger with using low doses of Resveratrol, but I'd recommend against going much higher.

Very good

Before I start taking this supplement I would get sick quite often ever since I have been taking resveratrol I have not been sick in a while. It's definitely worth the money.

As I age, my levels of "brain fog" has increased. I have been looking for ways to bring myself back towards the sharper focus of my youth.I've found no magic pill, but I noted that after taking this brand of Resveratrol for a month, I was less forgetful at the very least.I have now been using Resveratrol for about a year- since the end of 2019.I can honestly say I feel it has kept my "brain fog" at bay and I am more productive at work.After reading other reviews, it seems I am fortunate to not have experienced big side effects.

After starting to take this for a month or two I felt more rested in the morning, had an easier time to fall asleep (I take it right after dinner as anti-oxidants have different effects if you take them after sun set or before). Additionally I saw an increase in hair growth, on my fingers and legs. I researched both effects and found that these effects have been observed in individuals and monkeys, so I think the effect is real. To your information, I'm only 95 pounds, so my effective dose with 1 pill of this product per day is relatively high.
