Size Name:60 Tablets| Item Package Quantity:2|Amazon Verified Purchase
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.

Size Name:60 Tablets|Item Package Quantity:2
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.

compare the dosing
Before getting too excited about this product and the price for 120 tablets, consider the dosing. Two tablets twice a day - so this is a 30 day supply.
