Lewis Labs
Brewer's YeastFlakes



After an extensive worldwide search, Lewis Labs has finally found high quality, 100% natural, non-GMO, gluten-free, non-fortified, 100% pure Brewer's Yeast flakes that actually taste good. 

We all know how nutrients in vegetables and fruits vary depending on the soil in which they are grown. Take Idaho potatoes for instance - famous for being the best.   Why is that?   Because the nutrients in the soil are not found anywhere else.  Previously, our famous brewer’s yeast products were grown in Croatia where the soil is very rich in nutrients. Unfortunately, the supplier no longer produces yeast from their sugar beets. As a result, we searched the world for a replacement and have found the very best natural yeast from sugar beets that live up to our very high standards.

If Lewis Labs 100% Pure Premium Imported Brewer's Yeast™ Flakes are not part of your daily nutritional habit, they should be.  Brewer's yeast is one of the most perfect foods known.  Loaded with proteins, minerals and vitamins, it is amazing how much food value is packed into even a small amount. It provides the protein you want without the extra calories and cholesterol you do not. Since it is low in fat, carbohydrates, sodium and calories, it is especially useful for dieters and vegetarians. In fact, it seems to have a bounty of nutritional goodness for just about everybody.

Lewis Labs 100% Pure Premium Imported Yeast™ Flakes are derived from plant and microbial sources (the inactivated yeast strain, Saccharomyces cerevisiae, commonly referred to as brewer's yeast) and is nutritionally superior to ordinary types of yeast.  It is one of the best natural sources of the entire B vitamin complex. It is a superb source of concentrated protein including all the essential amino acids. In fact, brewer's yeast contains about ten times as much protein as the same amount of whole-wheat flour.

It is extraordinarily rich in nucleic acid, which is a essential element of cell development and is believed to have benefits on the aging process.  It is also rich in potassium and many other factors too numerous to mention.  All are in a form that is most available for immediate use by the body. With these nutritional credentials, why doesn't everybody take brewer's yeast every day? The answer is many people simply do not like the taste of ordinary brewer’s yeast products.

Lewis Laboratories has discovered and imported a truly unique brewer's yeast.  Not only does it taste good, but it has higher protein content and is richer in nutritional content than any other natural, non-fortified brewer's yeast product on the market. It is neither 'doctored' nor blended.  Absolutely nothing has been added to this 100% natural product.

How can pure, unbleached, untreated brewer's yeast taste so good? Of course, there is a reason. Most ordinary brewer's yeast is recovered after use in the brewing process. It is grown in vats containing grain, malt and hops. As the yeast feeds on this culture medium, it produces alcohol while it absorbs nutritional factors from the medium. At the same time, the yeast picks up chemicals and other undesirable materials. Although it goes through a debittering process designed to remove the contaminating oils, which are mostly lupulins giving it the bitterness, the recovered end product is less than desirable in taste. This debittering process also results in the loss of some protein (amino acids), minerals and trace elements from the product.

Unlike ordinary brewer's yeast, Lewis Labs' 100% Pure Premium Imported Brewer's Yeast™ is primary yeast grown on sugar beet molasses.   Derived from the sugar beets is an abundant spectrum of nutrients.   Sugar beets are known to absorb so much out of the soil (minerals, metals, trace elements, etc.) that they can only be grown in one field for two years without depleting the soil. 

Like our original yeast products, the Lewis Laboratories 100% Pure Premium Imported Brewer's Yeast™ Flakes process does not involve malt, hops and bitters etc.  It is drum-dried at very low heat (no higher than 60° C).  It has a clean, nutty taste and great nutritional value derived from the sugar beets.  It is a 100% pure and natural product.  The culture medium on which the yeast is grown is most important since it is from this medium that the minerals, metals and vital micronutrients are derived.  

We have done extensive testing and our lab has confirmed that our Brewer's Yeast retains a protein content of 45%-50% and a nucleic acid content of 6%-8%. It also contains approximately 3%-4% natural RNA/DNA from nucleotides.

It is important to note that brewer’s yeast is not related to the Candida albicans fungus, which can cause a yeast infection.

At the recommended serving size of 25 grams (3 level tablespoons) one can will last two weeks. 

Lewis Labs Brewer’s Yeast™ Flakes are kosher, parve and halal.

Lewis Labs Brewer’s Yeast™ Flakes are available in 12.35 oz. (350 grams) containers which are sold by weight, not volume.  Some settling may occur.

Lewis Labs Brewer's Yeast™ Flakes are sold under no other name or label.

Brewers Yeast

I have been using your Brewers yeast for fifty years to keep cataracts from forming in my various dogs' eyes. It works! It even will slowly reverse the cataract. My current basset hound, who is 12 years old was suffering, do to my inability to get this product for two or three months. I have been giving it to him again since Monday night when it arrived from you. I already see a difference. No other yeasts can do this! thank you!

Mega Nutrient

B vitamins, amino acids and minerals in one food plus it tastes better than any other brewer's yeast. Of course if you prefer the plastic stuff cobbled together in a lab this is not for you.

The more you eat the more you love it!

I use to eat this years ago, and when I got it back, I had to start slow and then increase a little bit by little bit. I love the taste and have it every morning and once in a while with another meal. I love the taste and recommend it highly. Lots of great nutrition in this product! I'm glad Lewis Labs could bring it back to the market. - Janis Ihrig
