NOW Supplements, Natural Resveratrol 200 mg with Red Wine Extract, 120 Veg Capsules

Potent antioxidant and anti-inflammatory remedy

I bought this brand of resveratrol because NOW has a good reputation and good prices. There are, however, other reputable sources for resveratrol. The following brands have been tested by the independent Consumer Lab, and approved as not containing contaminants and containing the amount of Resveratrol they advertise: Bulk Supplements Country Life Doctor's Best Dr. Whitaker Finest Nutrition (Walgreens) Life Extension Life Smart Labs Longevinex Pure Encapsulations Puritan's Pride ShopRite Solgar Spring Valley (Walmart) Trunature (Costco) Vitacost Vitamin Shoppe Vitamin World Resveratrol is a powerful antioxidant which is found in many foods, most notably in raw cacao, peanuts, berries, red grape skins and pomegranate. Resveratrol belongs to a family of compounds known as polyphenols, and it is a primary healing agent found in herbs which are known to nutritional scientists as "adaptogens." These herbs act to support the immune system and prevent degenerative diseases. Examples include turmeric, rosemary, ginger and green tea. Research has indicated that resveratrol is anti-inflammatory, which is a crucial benefit since inflammation has been found to be a direct cause or contributor to every major disease, including heart disease, diabetes, and autoimmune disorders such as arthritis. It is capable of crossing the blood-brain barrier, which means it has the ability to moderate inflammation in the brain. This makes it capable of preventing and helping mitigate the ravages of Alzheimer's and improving cerebral blood flow, which is good news for preventing stroke and dementia. Resveratro has also shown significant promise in preventing and healing cancer. The mechanism by which it has an anti-cancer effect is this: It helps prevent the formation of enzymes which trigger tumor development, and it helps reduce the out-of-control cell division of "immortal" cancer cells

A bit of science

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

Welcome to the Diarrhea party

I bought a res product on Amazon a year or so ago, and didn't have any problems with it, apparently standards have really gone down since then. Almost all of these products contain reviews like this, and I thought they were just trolling, but now I know otherwise. Google emodin to see what it's all about. My search for a low emodin resveratrol continues

Headaches for DAYS!!!

Resveratrol gave me terrible debilitating headaches so beware! I woke up three days in a row with headaches that didn't go away all day. I hadn't had a headache in weeks before this and while I am headache prone, this was a terrible headache. Like the kind you get from a hangover of drinking too much wine, but it didn't go away after a few hours. It was constant for three days!!!! Miserable!! That's when I put two and two together and realized it had to be the supplement as I had only been taking it three days and it is in red wine.. Which causes headaches..for me anyway.. After I stopped I started feeling better... So if you're headache prone or are sensitive to red wine beware! The article I had read about the supplement said to take up to 1,250 of the supplement a day for it to be "most effective" but I don't even care to try lowering the dose because these headaches are not worth it

Disappointed

I wanted to like this product. I really did. I heard about the health benefits of resveratrol all over the internet, so I ordered this from online since it seems to be a pretty reliable brand. The first time I took the pill, I took one pill in mid-morning with food each day. However, by the third day I woke up with a slight cough and sore throat. I stopped, and the next day my flu-like symptoms went away. I wanted to give this product the benefit of doubt, so I waited another month and tried again. Again, I felt like I was breathing like I was sick by the third morning of taking this pill. I stopped again and the symptoms went away. I tried it ONE MORE time in the past few days, and the same thing happened again. I don't know what is wrong, but maybe I have allergies to this pill? I don't think I experienced any of the appetite suppressing, metabolism boosting, and energy giving effects of the pill. Whatever the case may be, I was sorely disappointed by this product and will not order again

Horrible

This is the very low quality kind made from root extract. The root extract has emodin in it, removing the emoding is expensive, so they leave it in, but the result is very heavy diarrhea which negates any beneficial effect this might have. This product is simply dangerous

Good for what “inflames” you.

My much better half takes numerous supplements for inflammatory problems throughout her body and decided to try and save a little $ and skipped on the NOW Foods Natural Resveratrol, Mega Potency, 200mg, 120 Vcaps for a month. Like most supplements it can be hard to tell when they're working, but after a month of being off the NOW Resveratrol she definitely notices an increase in symptoms. She's back taking Resveratrol and this is the 6th time we've ordered the NOW Brand and we will definitely be keeping it in her regimen

Tried RezV for 4 days!

I tried taking RezV for four days. By the second day, I was feeling nervous, hyper and unable to relax or sleep well, so I changed the doze and only took 1 pill instead of the recommended two pills. By the fourth day, I was totally wired and unable to sleep at night. It was like taking some sort of diet pill. Definitely did not like it and it did not work for me. I promptly canceled my order, but continued to get the monthly shipment. Kind of a waste of time and energy. I think it is pure Hype!

Waste of money

Realistically this product contains so little Resveratrol you would need to take the whole bottle to equal one does of the active ingredient. Each capsule contains fillers and binders. The bottle contains 5 cents worth of the active ingredien

Horrible for me

Gut wrenching diarrhea with this supplement. It seems to be due to the source of the resveratrol -- Japanese Knotweed. I'm going back to the more expensive brand that is sourced from grapes
