The B-Vitamin content looks rather low relative to the B-Complex I currently take. It does however look like an great source of all kinds of aminos.

It doesnt mention any cartenoids, like Asthaxanthin though.....why?

Lynx, ScottL what do you think

[scottl]

Asthaxanthin one can obtain from salmon (along with omega 3s).

Caroteinoids come from veggies (in general). Best eat carrots, cooked tomato products, diffferent colored peppers, spinach.... OR get a good multi-carotene product. I've finally found one I consider the best--Jarrow brand carotenall. Jarrow makes excellent products.

Ah, stellar Stellar. You've corrected me probably, good job. I thought I remembered seeing a reference to brewer's yeast having available astaxanthin but I am probably wrong. I see that it may have been perhaps a generic reference to nutritional yeast having astaxanthin as one does, but not necessarily brewer's yeast or any other. http://www.diamondv....et/booklet.html seems to cover a number of different yeasts used in feed supplements for food animals. Here is a quote:

Phaffia Yeast

Phaffia rhodozyma, known as Phaffia Yeast, is the latest yeast product to enter the feed industry. This yeast produces a red pigment used in trout and salmon feeds for its red pigmentation of the meat. This red pigment is a carotenoid called "astaxanthin". Phaffia yeast is more expensive than the synthetic form of the carotenoid, but limited data suggests that astaxanthin from ruptured yeast cells may be a more effective pigmentor since it is in an organic matrix.

I understand that what you are saying, Scott, does not literally imply that this is not the case but, just to be redundant, astaxanthin is a carotenoid.

Apparently Phaffia rhodozyma has been given a different name recently, Haematococcus pluvialis, as noted at http://www.astaxanth...g/chemforms.htm Here is a quote from that site:

Why do we think natural astaxanthin may act differently from synthetic astaxanthin?

All-E isomers are the major geometric isomers in both synthetic and natural astaxanthin (Turujman et al. 1997). However, synthetic astaxanthin is produced as free (unesterified) astaxanthin in a mixture of stereoisomers: the stereoisomers (3R,3'R), (3R,3'S) and (3S,3'S) occur in a ratio of 1:2:1. Natural astaxanthin, on the other hand, is usually esterified and predominantly of (3S,3'S) configuration or, less frequently, mainly (3R,3'R) (Bernhard 1990). In Haematococcus pluvialis, astaxanthin occurs as the 3S,3'S stereoisomer and primarily as monoesters (>90%), with diesters comprising ~8% and the free molecule ~1% (Renstrøm et al. 1981). It tends to produce higher pigmentation in rainbow trout compared to synthetic astaxanthin provided at the same dietary concentration (Bowen et al., 1999).

Sorry for having jumped off the handle with the brewer's yeast claim as a source of astaxanthin. I bought many bottles of an astaxanthin supplement from red algae aquaculture some time ago and pop at least one a day, usually, 4 mg.

Why does brewer's yeast turn my pee bright yellow? I see reference at one of the sites above that astaxanthin in the right matrix does result in a yellow pigmentation so I'm currently only about 80% sure it is not in brewer's yeast at the moment but that is no confidence factor worthy of supporting my claim that brewer's yeast was a source. Do some of the B-vitamins have a yellow color? Is this any relation to a niacin flush?

Phew, got to be careful, being corrected and correcting oneself can be time consuming. I welcome it though. Thanks Stellar and Scott.

Chip,

I must have missed the original comment and didn't know I was correcting you.

"Vitamin B2 Riboflavin has extremely low toxicity. As a result, dosage precautions for riboflavin are mostly unnecessary. The body has a limited capacity to absorb and store riboflavin, which is water-soluble, and excess amounts are simply excreted with the urine. High does may cause the urine to become bright yellow in color. This color change is harmless, but high levels of riboflavin B2 in urine could interfere with certain urine tests."

http://www.nutrition...riboflavin.html

I do not think it is related to the niacin flush which is histamine mediated.

[Chip]

Thanks. Well, now I'm close to 90% confident that brewers yeast is not a source of astaxanthin.

Ok. Considering ALOT of life enhancing or longevity supplements trials are done on rats and other animals, I don't see a problem... If you are looking for human experiments on every thing you take, than you will end up taking almost nothing except pharmaceutical drugs. But I must say, I did laugh pretty hard at your reply

I take a lot of supplements, and they have ALL been tested in humans.

Glad you laughed. Just joking around, not a serious reply.

I do take Brewer's Yeast, though not based on the striped bass study. I wouldn't mind having a more in depth discussion on it. There was another recent discussion where I posted some links to some different brands. There is a lot of variation in this stuff regarding vitamin content.

Yea, I just discovered this supplement. I must say I really like it. How much variation is in this yeast? I take the GNC brand :S Is that alright?

[kismet]

Weren't you considering or taking resveratrol? (the one with no long term studies, or what's the current record holder?)

I wouldn't generalise as to never taking supplements untested in humans, because it really depends on the *class* of compounds and other variables. We're taking in millions of untested substances every day, we call it food. Which is the reason why if we're supplementing food-like amounts we can get away with a different level of evidence (sometimes)...

Doesn't list many vitamins in it on the GNC site. Compare it to some of the descriptions on iHerb.

But who knows, maybe they're just not listing all of the vitamins. It could be a variation in labeling more than a variation in substance.

It's odd that NOW brand lists more vitamins for its loose powder than it does for the tablets.

I can confirm the brewer's yeast I have (NOW brand tablets) doesn't work well for acne

There are a bunch of clinical trials in progress, and several completed. You're right though, the ones that are complete were not that long. At least it's been in humans under decently monitored conditions; it's not like I started taking it based on the yeast results...

For all I know, indigenous people have been eating large knotweed salads for millenia. (ok, I made that up...) But I wonder if I should consider some of the things I eat to be food or drugs. I use blueberries and cocoa very regularly, more like a drug than a food, although I like them as foods too. Normal food use would be more infrequent, I'd think.

[eason]

Yes, niner goes around trashing everybody's regimen when he takes many supplements himself that have not been tested long-term in healthy humans (carnosine, resveratrol, ALCAR, Biosil). He's a hypocrite.

[kakker]

I've recently started using Brewers Yeast (primarily as a source of B vitamins) as I move toward a CRONish diet. I'm using Solgar's Brewers Yeast. Wow, this stuff tastes awful! It's quite disgusting.

You violated our posting guidelines on your first post. Good job. How about pointing out some examples of my "trashing" of "everybody's" regimen?

I can't say yet. I've only used it for a few days.

What are you hoping it to do?

[medicineman]

I take a lot of supplements, and brewers yeast seems like the only one I have gotten a noticeable effect off... in terms of energy and alertness. but I am taking like 16 x 500mg tablets a day.
