Anthony,

You could buy 50% yourself and clean it to 98% with the proper lab equipment.
But, the chinese chem vendors appear to process this for less money.

I have a Kilogram of 50% RSV very clean, with a valid COA
From two vendors 100 grams of 98% RSV plus a 20 gram sample 98% RSV both with COAs

I can buy Kilograms of 98% for $725 Kg

Inspecting the COA on the 98 I can see how they purified it.
The 98% organic RSV has been cleaned using water, alcohol and EDTA.

I told Paul that I did not wish to buy any 100% synthetic RSV for $405 per 100 grams.

Since the 98% has been cleaned well enough for my purposes.

I have enough RSV for my wife and I for one year.

I believe Orchid has patented their product internationally, so I am hesitant about this being the same as Orchid's synthetic rsv. It will likely be 98 or 99% resveratrol which can be purchased at a better price.

If you are interested in 98% pure resveratrol, email me.
I believe pricing is...

$200 for 100 grams which is sold for manufacturing as it is not encapsulated. It's also not on the price list, as we are still looking at the marketing aspect of it.

According to the chart you posted, Paul's powder will be approximately... 
$405 for 100 grams.

Is the difference of 1% (maybe 2%) purity worth the additional $200? If the molecule is the same, personally I would get the cheaper one.

Oh, yes I almost forgot, RevGenetics will also give you the option to purchase the new "RevGenetics Shield" product to protect your powder from any perceived long term oxidation from storage. We just got 3 cases of it, just for small manufacturers that purchase powder and are concerned about long term storage.

I agree bixbyte, it is the same molecule.

How you get it (whether by extraction, or synthetically made...) really doesn't make a difference.

In the end you produce the same molecule.
At least that is my take on it.

Anthony Loera

[tintinet]

Likely so. Effects, at least according to the studies I've read, appear to be similar with use of either extracted plant-derived t-rsv or synthetic. Sinclair's recent rodent studies used synthetic, but, likely, this simply provided a more straightforward, ostensibly uncomplicated version of t-rsv. to avoid any possible issues of effects due to "accompanying" substances that might be harder to eliminate or standardize if using a plant extract.

Does anyone have a reference for that method? Just out of curiosity.

RSV Dissolves ethyl Alcohol
RSV slighty dissolves in H2O
If you had a buchner funnel
very easy
It would not take long for an organic chemist to write the process

I think you can purchase the document with the process from here if you are a student looking to do this:

Thanks very much! At a minimum it will make for some interesting reading.

[macanizer]

Jarrow's Resveratrol has only 16mg of resveratrols, according to their supplement facts. Am I reading this wrong?

[Anthony_Loera]

Yeah, I think you are reading it right.

It must be an older formula, as the one I have in the list (with a link) seems to have more.

[tintinet]

Woa, Anthony, your R350 capsules are about as big as any capsule I'd ever want to swallow. I take it the R500s are even larger???? Ouch!!

[Anthony_Loera]

Actually we initially started RevGenetics using this same size capsule for the R500s. When we added R350 for we didn't change the capsules. We began using 700mg of powder in each vegetarian capsule instead of 1000mg, for the R350s.

Having said that...

We will be using smaller vegetarian capsules for the R350 soon. The smaller ones will hold 700mg of powder without a problem.

We are checking to see if we can do the same with 1000mg, but so far, various encapsulation machine manufacturers have told us it is difficult. We will still have the R500s using the same capsules for now.

We will keep checking though.

Thanks
Anthony Loera

[tintinet]

Much to my surprise, although the size of the R350/R500 capsules is daunting, I swallowed them without incident, on several successive occasions. So far, no Heimlich manuevers required, but I'm still a bit wary....

[Anthony_Loera]

Yes, the vegetarian capsules are really great and easy to take.

I find them much better to take than the gelatin ones.

[Anthony_Loera]

Just a reminder,

please let me know if you guys run into prices for one product or another on this list, that are better than those on here. I will then make the change on the worksheet.

Thanks
Anthony

[Anthony_Loera]

Well... it had to happen.

A new low price leader has shown up for folks that like powder resveratrol.
Check out the worksheet.

Anthony

[malbecman]

Both 50% and 98% purity products, interesting. Low emodin on the 98% stuff. Really good prices per gram for 50%, maybe a little
high on the 98%. (?)


I think I could have come up with a better name than Mega-resveratrol, however. [wis]

[PWAIN]

Anthony,

I must be missing something. You quote 56.666 cents for the 120grams of 50% but I thought we were concentrating on Trans-Resveratrol. That would be approx 60 grams so the price would double to a $1.13.33333 which is more than the BAC product. Same applies to their other 50% product. If you aren't going to concentrate on the 50% then BAC is supplied as 25grams of 50%.

The 98% is also off but the difference is more marginal.

[hormoneman]

Mega resveratrol cahrges $2.15 per gram for 120 grams but you say you can sell 100 grams for $200 - aren't you still cheaper?

[Anthony_Loera]

Hi guys,

I have had a very long weekend and had an emergency come up. So I will check pricing on the sheet monday morning, and will edit it as necessary.

Hormoneman... you are correct, but until my website is finished by the guys at helldesign, I will leave my pricing off the worksheet as I would need to also offer a direct link (which is something i don't have at the moment).

Thanks
Anthony

Hello everyone,

A couple other resveratrol users and I have come across a company advertising 98% and 99% trans-resveratrol extract powder:
Changsha Organic Herb, Incorporated, based in Hunan, China. Changsha's Website or http://www.organic-herb.com.

As it stands, the current (as of 4/30/07) quoted cost of 98% and 99% trans-resveratrol is $680 and $800 U.S. Dollars respectively, per kilogram- extremely inexpensive (68 and 80 cents per gram). Orders for quantities below one kilogram are also allowed, but the price is slightly higher. This eliminates the need for a bulk purchase.

The purpose of this post is to enlist other users who would be interested in purchasing this product individually, but would prefer to have it independently tested and assayed beforehand. Due to the considerable cost of such testing, we propose splitting the analysis expenses. At the moment, three of us are interested in having this product tested and are planning to test the advertised 99% trans-resveratrol.

The cost of the complete testing, which includes HPLC analysis for trans-resveratrol, cis-resveratrol, and emodin along with testing for the heavy metals mercury, lead, arsenic, and cadmium, and a plate count, is $600 U.S. dollars. Two of us have recently ordered from this company and have found that the product seems to be of very high quality and the company seems to be professional.

If you are interested in possibly purchasing this product and prior to this would like to have it independently tested and analyzed by American Analytical Chemistry Laboratories Corp. (http://www.aaclabs.com), please let me know. The $600 dollar cost would be split among all of us (however many sign on to share the analysis expenses), potentially making testing much more affordable.


Thanks.

[rwoodin]

OK, Just bought some 98% Mega-Resveratrol because I'm getting tired of the Mega-laxative-effects of the emodin in the 50% and below extracts. I have also read on some threads here that people were not experiencing the hyped up feeling with the 98% tres that is produced by a lot of the lower percentage extracts. I didn't start taking this stuff to 'feel' anything other than better health and longer life. And to keep on topic, the price is pretty good. And finally, Anthony if you want, Natures Way sells resveratrol 75mg 50% synergistic formula that could be added to the price list. The list is a useful tool for consumers.

Thanks rwooden, I will put it up in the sheet tonight.

Please see my posting in the '500 club' thread on having personally lab tested their product (excellent) and having tried to do business with them (impossible).

Big thread, that, proteomist! Couldya link it?

Thanks!

[proteomist]

Turns out the story is still developing and their failure to respond may have been due to technical issues (though I sent email from multiple accounts) as others have been in touch with them. I hope that's all it is, since otherwise they're very attractive. Anyway, it's on the last current page of the thread here.

Hi resvhead,

This has been corrected, and updated on the worksheet. Thanks for catching it!

[Anthony_Loera]

Anthony if you want, Natures Way sells resveratrol 75mg 50% synergistic formula that could be added to the price list. The list is a useful tool for consumers.

http://www.natureswa...x?s=resveratrol

I found this one 'Natures Way' for little over $9, and put it in the worksheet. Let me know if someone finds it for less. Even though 'Natures Way' says 75mg, each capsule actually has only half of that, so in the worksheet you will notice that the capsules less to calculate the total amount properly.

thanks
Anthony

[Anthony_Loera]

Andrew Lessman's ProCaps Resveratrol 100

has been added to the worksheet and html page.

[ironchet]

Why isn't there any capped 98% RSV? surely there must be market for this.
