Vita Prime Lab's 99% Resveratrol:

I bought 200 grams of 99% RSV from VP Labs came with a 99.12% COA included.
Stuff is caked and was never fine mesh processed.
$63 for 100 grams or $650 for a Kilo?
I do not know why they charge less for 100 grams.
Spoke to owners Wife today.
She told me they sold 1,000 grams so far.
Their stuff is pure but crude.

I have to run the ultrasonic cleaner for a good 3 minutes to dissolve.
Looks exactly like the 50% red RSV but it is off white and tastes like real strong Res.

You definately can not cap their stuff and absorb it as it needs further processing but it can be taken
with miralax and ultrasonicated for at least 3 minutes.
Probably burn out my ultrasonic cleaner. Their RES is "Ruff" powder.

Just curious, but
why would she mention this? Is this their first time selling resveratrol?
Is that 1000 grams, 100 grams at a time?
Did she mention how much product they actually have at their disposal?
It does appear to be a batch that didn't measure up to standard, but
how did Vitalprime come to obtain it if they haven't been in the resveratrol
market before? (I'm assuming they haven't or we would have heard about them)
I don't really expect answers, but it makes me wonder.

Now now, first of all my camera is crap, I mean really bad. Second the original package was packed very tightly almost like a vacuum packed package, anything you pack that tightly and then transfer to another container is going to cake somewhat. Now I could have smoothed it all out for you all nice and pretty and got a high resolution camera instead of my camera phone. Anyways, it dissolves fine in oil, confirmed that tonight. PEG with a hand blender and warm water leaves some residual but not bad. I'm still not buying the whole milk protein thing so I'm not trying that (gave up on the whey idea). The only reason I care what others think is that I suspect that for this guy's business model to work (and for me to have a steady supply) he is going to need to sell truck loads of the stuff. Either that or he has simply gotten a one time shipment through connections and once its gone that will be it. Anyways, once another lab, or Hedgehog confirms things I will be more than happy.

My sample still hasn't arrived. Somebody is sending my a 200mg sample to do a more indepth test. However, I won't be doing any heavy metals testing. Just GC, IR and HPLC. If GC looks good than a water analysis or TGA (shows OVI + Water content) is in order.

Ok, it seems that Biotivia is back on the list. James has asked us to publish his prices in the yahoo groups.
I think he plans on reducing them soon.

This is good. I would like to see all the vendors feel free to post their information here and comfortable about doing so.

Yikes,

someone pointed out that I took vitalprime off the list, when I added another product. (I believe I used an older version of the excel file, my apologies). Let me put them back on, in a bit...

Hi everyone,

What about this supplement? Puritan's Pride Resveratrol 50mg $8.97 (60 Capsules). I don´t know about this company Puritan's Pride but this product is really cheap. But I have doubts about its Total Trans-Resveratrol (grams). I asked to them about the total trans-resveratrol and they answer to me quickly. Their answer was:

Dear Valued Customer,

Can't tell what is in the Puritan Pride bottle from the label. It is most likely a 50% trans-resveratrol extract from Polygonum cuspidatum, but whether there is 50 mg of the extract yielding 25 mg of trans-resveratrol, or enough extract to yield 50 mg of trans-resveratrol is ambiguous. It is cheap, and could even be a 20% extract, and so could be as little as 10 mg of trans-resveratrol.

Nightwing, the best case scenario is that each capsule contains 50mg of trans resveratrol. If that's the case, then 60 of them gives you three grams for almost 9 dollars, or very nearly 3 dollars/gram. That's not a very good price for resveratrol. I'd look elsewhere.

ps: I edited your post to remove content that could be construed as commercial, as the forum tries to remain very non-commercial.

Puritans Pride, I have always had trouble swallowing their tablets.
They always stick to my tongue.
So, I would avoid their tablet supplements except for their capsules or liquid caps.

Puritan's Pride --> Good price?

Can anyone do math?

I Received email from VP labs.
They claimed 99% BUT Vital Prime is 87% RES

I converted the PDF file to text format:

A while back I believe you said that you sent in Vital Prime in the unopened foil bag you received it in for testing at your independent test lab, AACL. Have you received a report back and did you request heavy metal testing as well as t-res content? You said as long as there was nothing wrong with the Vital Prime material, you would post the results for ImmInst.org Forum readers.

Thanks

Yeah I'd like to see the results to. Either I got the email and it got lost in my inbox or I didn't get it, so this is the first I have heard of this. So ok at 87% (by weight) the price per gram is still $0.72 for a 100 gram order which is still amazing... Ok we know 2.0% is water so that leaves 11% unknown. I would really like to know what that 11% unknown is, if its residual plant matter, cis res, polydatin, emodin, etc etc. I'm ok with that but heavy metals, solvent residue, industrial chemicals etc. well thats a problem. Interesting that hedgehogs analysis showed only t-res, but I guess he was going for t-res vs. cis res and only found t-res so I guess that crosses one unknown off the 11% list.

Yes I concur, thanks for this Anthony.

Hi Edward,
I'm curious to know how you are finding the VitalPrime Res. How much are you taking and
are you having any GI issues. I know I am with 98% doing 2 grams a day. Wasn't there
a COA done independently by VitalPrime? I remember reading they were doing it. Did they?

[Anthony_Loera]

Honestly,

I believe AACL will come back with a good COA regarding heavy metals and the like. Many (not all) Chinese resveratrol suppliers we stopped using, initially did test well.
But bad batches do happen, and that's what testing is for, to catch the bad batches before they are made available.

Thanks anthony! Are you doing the USP heavy metal testing or the 60 metal scan? USP tests for only certain heavy metals that the USP considers as "heavy metals" the other 60metal scan is about twice as much and probably isn't needed.

This is the lab I use and I think it costs about 200 bucks for a ICP-MS heavy metal scan

You are joking
I think it matters, heavy metals are accumulative

[edward]

Pretty sure he is joking.

By the way, the vital prime seems to work just like other sources of Res I have taken. Currently (as of today) I am taking 2 grams a day actually 1.6 grams vital prime and 400 mg from BAC 50% as the 50% has always given me an extra boost in energy (probably the polydatin and other plant compounds in it). Well actually now that we know it is 87% by weight my total daily dosage is 1.392 + 400 mg so about 1,792 mg. I dissolve it in oil as I have mentioned and add lecithin. Miralax ahem makes me a little to loose lol.

[Anthony_Loera]

Edited VitalPrime price.

Hi Everybody,

I'm a newbie, and I have read much of this thread, but I am still a unclear on the meaning of one of the columns on the pricewatch spreadsheet, namely Quality. If a product is listed as 50% under Quality, what is the other 50% of the product comprised of? Is it filler, impurities or what?

Thanks,

It's impurities, or if you want to be charitable, it's the other wondrous compounds besides resveratrol in Japanese Knotweed that were placed there by Gaia Herself for our benefit. And to give us the runs.

Referring to emodin, a potent laxative which runs 5 to 10% of a 50% extract. The remaining substances are miscellaneous anthocyanins, cis and trans-resveratrol glycosides.

New RSV player (synthetic for the masses), claiming 10 years of develoment (1998 - while we were all playing in the sandbox)

http://www.nutraingr...veratrol#jumpAd

A few sparse quotes:

20-Mar-2008 - DSM has launched a new resveratrol product, which it claims plugs a market need for a high potency ingredient supported by an extensive safety package.
Resvida, which has been in development for the past ten years, was introduced to industry last week at Supply Expo, part of the Expo West trade show in Anahein, California.

DSM recommends that its branded ingredient is used at 30-150mg per day.
...
Resvida is a synthetic resveratrol, but is said to be 'nature identical'.
It comes in two forms: a crystalline form, with 99 percent purity; and a tablet grade form, with a purity of 90 percent.
According to DSM, this is the purest form of resveratrol currently found on the marketplace.

Another major selling point that the company is promoting is the safety package surrounding the ingredient, which it claims is unmatched by any other form of resveratrol currently available.
"Previous New dietary ingredient notifications were rejected by the FDA because sponsors did not provide a thorough safety assessment," said DeJianne.
"We have performed a very comprehensive safety analysis around this ingredient. That's why it has taken around ten years of work to bring the product to market."

DSM has also conducted its own clinical study on the ingredient, which is currently being peer-reviewed. The company expects this to be published "later this year".

[Anthony_Loera]

Resvida is a product for manufacturers.

Which means that manufacturers would have to deal with the FDA because of it's "synthetic" nature, not the resvida makers.
I see no one selling this at this time.

Resvida cannot claim to be an "herbal supplement" because they are marketing it as a synthetic.
This is not a topic for the price watch until a link is provided that has an actual product for sale.

thanks

[Anthony_Loera]

I believe after the Barbara Walters special on "Live to 150", we will start seeing many more folks introducing higher dose resveratrol capsules. I say this because of some phone calls I got on April 2nd that lead me to believe that some larger companies are taking notice.

Please keep an eye out for these in the coming weeks, and let me know when you spot one, I'll add it to the list.

thanks
