the packaging has changed but the "Source Naturals" "Resveratrol" I received has 159 mgs of Calcium, 10 mg of sodium, and only 20mg of Resveratrol. I feel this was deceptively advertised. If I wanted Calcium I would have bought a Calcium supplement. The Labeling should be Calcium (the main ingredient) not Resveratrol.

I started using this a few years ago when I ran out of my usual brand and a friend gave me his bottle. The other brand had a much higher dosage of resveratrol and I had never noticed any particular effects or benefits. It also cost more. What struck me about this one is that the pills are brown instead of white and have an herbal smell.

Two days after starting the Source Naturals tablets, at half the recommended dosage, I noticed that my asthma symptoms began to diminish. Within a couple of weeks the occasional minor arthritis in one of my fingers stopped burning. I have taken the full dosage ever since.

These benefits have continued, and those two issues rarely plague me. Only once since I started taking this 40 MG dosage have I run out for any length of time and after a few weeks my asthma got significantly worse and my finger joint began aching again.

The bottom line for me is that this is one of those rare supplements that actually have tangible benefits. The other brands of resveratrol may have better numbers printed on the label but this one actually works.

Labeling standards for resveratrol tablets are inadequate. I spent way too much time researching this issue. The maker of this product obfuscated their labeling. The labeling on the front claims 40 mg Total Resveratrol. The detailed label on the back claims 20 mg for Serving Size: 2 Tablets. That's only 10 mg resveratrol per tablet. This is also viewable on their web site.

The detailed Source Naturals back label, also replicated on the Source Naturals web site, shows a confusing medley of other ingredients. They've added root extract that bring up "Total Resveratrols" to 80 MG for a 2-tablet serving. Yet Source Naturals claims only 10 mg resveratrol per pill just below that. The pills also contain hydroxypropyl methylcellulose, maltodextrin, colloidal silicon dioxide, and magnesium stearate and provide a little calcium to boot (159 mg for the 2-tablet serving).

The too-good-to-be-true low cost of these tablets is just that. No wonder resveratrol products are marketed by extolling the health benefits of a mysterious ingredient that is only present in small amounts. One needs an unabridged dictionary, calculator and multiple-monitor workstation to figure it out. If we want calcium, we can get 600 mg calcium pills for much less.

What I also found out about resveratrol surprised me. We should be looking for a trans-resveratrol supplement, not merely resveratrol. Trans-resveratrol is the active form, remaining active only when kept from sun, light and oxygen. The studies indicating the multiple heath benefits we're after are based on trans-resveratrol. I believe this makes consideration of the Source Naturals offering moot.

I purchased this product believing it was the real deal. I even had it briefly as a subscription purchase. If you've wasted money on mislabeled products, know you're not alone.

I like it, and we trust the Source Naturals brand with its listed potency of the resveratrol ingredient. Shipping is also free from DAB.

I've previously tried Longevinex which is much more expensive and has a very strange oily consistency inside of the capsules. These are solid tables with little filler that smell like grains, probably from grape seed. It does not upset my stomach, which is great, too.

Resveratrol is the 25 year cure with many positive interactions with health maintenance and interrupting the disease process that make it essential, especially for adults over 30 when aging begins to occur.

Deceptive product, that is dosed way too low. Yes, resveratrol is expensive to produce, and yes there are a lot of products out there that will try to sell you a low dose so they can make money. You would have to take more than 10 pills to get the same amount of trans resveratrol as some of the other choices on amazon. So if you are concerned about your health, get a product with a better dose, like 500mg, not 40!

What I received was not the same product that is pictured here. The Source Naturals Resveratrol product pictured here is something I have bought before. The main ingredient in that product is resveratrol from the root of Polygonum Cuspidatum (Japanese Knotweed). There are no red grape skins in that particular product, and there are 40 mg of resveratrol in each tablet (as the front of the bottle states).
However, Source Naturals puts out a different Resveratrol product that contains red grape skins as well as Japanese Knotweed. That product has a picture on the front that includes, appropriately enough, a picture of red grapes. That is the product that I received.
There is nothing wrong with red grape skins, mind you, but what I wanted to buy was Japanese Knotweed, not red grape skins. I had reasons for that.
The product pictured here is not the product I received, so I was not happy.
