Is this Brewer's Yeast Brand Alright?

Hey everyone!

I'm going to start taking Brewer's Yeast, and am going to buy it from my local Vitamin Shoppe, could anyone tell me if there are any problems with this NOW brand?  They are supposedly a very good brand, but I haven't really researched Brewer's Yeast too much:

Any help would be appreciated, thanks!

EDIT: Also, since I asked already, how's this for a B-complex supplement? Serving size is 2 capsules, could easily start out with 1, seems very cheap, and LE is a very good brand;

I found this site with good info. http://www.livestrong.com/article/176197-what-is-the-difference-between-brewers-yeast-nutritional-yeast/

Brewer's yeast has a bitter taste that offends some taste buds. It may even have a beerlike aftertaste, which reveals its origins. Nutritional yeast, however, is cheesy and nutty without the bitterness of brewer's yeast. You can stir either yeasts into sauces, add to soups or whiz into a smoothie. Nutritional yeast is tasty enough to sprinkle straight over popcorn or pasta to mimic Parmesan cheese. Nutritional yeast is superior if you're looking for a vegan replacement for cheese in macaroni and cheese or nacho cheese dip. If you're committed to brewer's yeast but are offended by the taste, look for debittered varieties.

Nutritional yeast is a powdery or flakey yeast usually bought in bulk. Vegans and vegetarians enjoy it as a supplement, but others can benefit from adding it to their diets. It's usually a form of Saccharomyces cerevisiae, which is harvested, pasteurized and dried to deactivate it and enhance its nutritional properties. Brewer's yeast has a similar look and is also derived from Saccharomyces cerevisiae, but it's produced as the byproduct of beer-making. It, too, is pasteurized and deactivated.

Nutritional yeast offers substantial amounts of niacin, folic acid, zinc, selenium and thiamine. Manufacturers often fortify nutritional yeast with vitamin B-12. For vegans, this is an essential addition because they are susceptible to B-12 deficiency since the vitamin is usually found only in animal-derived products. Nutritional yeast also offers a number of essential amino acids, the building blocks of protein. Brewer's yeast offers an array of B-complex vitamins, selenium and protein, but it's also rich in chromium, a trace mineral that regulates blood sugar levels. Brewer's yeast does not provide vitamin B-12, while nutritional yeast does not provide chromium. Vegans looking for a B-12 supplement should stick to nutritional yeast rather than brewer's yeast.

Thanks that's interesting! I think I'll go for brewer's yeast then, especially since I don't mind the taste.
