They will not turn gooey in your mouth. Ideal for sprinkling on foods: cereal, salad, yogurt or adding in the last few minutes of cooking to bread dough, soup, etc.These tiny buds are formed by an exclusive space-age process called Air Flotation Agglomeration. The result is a more delicious, more uniform and more rapidly dissolving product. Ideal for use in liquids.

Brewers 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 dont. Since it is low in fat, carbohydrates, sodium and calories, it is especially useful for dieters, vegetarians, diabetics and hypoglycemics. In fact, it seems to have a bounty of nutritional goodness for just about everybody.

The microscopic plant, saccharomyces cerevisiae, commonly referred to as brewers yeast, is nutritionally superior to all other 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, brewers 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 basic element in cell development and is believed to retard the aging process. It is the best nutritional source of chromium, which occurs in brewers yeast in an organic compound known as GTF (glucose tolerance factor). This vital factor is essential for the production of functionally effective insulin, without which the body cannot handle glucoseits major fuel. Hypoglycemia results when the blood sugar level rapidly shoots upward, followed by a rapid release of insulin, which in turn overshoots the mark and drives the blood sugar too low. The role of GTF is to moderate insulin activity. First, by potentiating and circulating insulin and then by reducing the amount required to be released. This moderating effect of GTF is important, not only for diabetics and hypoglycemics, but also many of those who have increased hunger or craving for sweets. Brewers yeast has at least ten times more GTF activity than any other natural food..

As if this were not enough, it is also rich in Selenium, Potassium and many other factors too numerous to mention here. All are in a most available form for immediate use by the body. With these nutritional credentials, why doesnt everybody already take brewers yeast every day? The answer is, many people simply cannot take the awful taste.

Lewis Laboratories has discovered and imported a truly good tasting brewers yeast. Not only is it good tasting, but it has a higher protein content and richer nutritional content than any other natural brewers yeast on the market. It is not fortified, nor blended. Absolutely nothing has been added to this natural product.


How can pure, unbleached, untreated brewers yeast taste so good? Of course, there is a reason. Most brewers yeast is recovered after use in the brewing process. It is grown in vats containing grain, malt and hops. As the yeast plant 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 bitter taste, t:" ":erals and trace elements from the product.

Lewis Laboratories' 100% Pure Premium Imported Brewers Yeast is not derived from the brewing process and needs no debittering. It does not go through any chemical processing. It is a 100% pure, natural product retaining a protein content of 55-60% and a nucleic acid content of 8-10%. This is the reason it is completely digestible and functional and why many people who are allergic to other yeasts have no problem with this one. 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. Unlike ordinary brewers yeast, which is grown on grain and hops liquor, Lewis Labs' 100% Pure Premium Imported Brewers Yeast is a primary yeast grown on sugar beets. Derived from the sugar beets is a rich spectrum of nutrients. Sugar beets are known to absorb so much out of the soilminerals, metals, trace elements, etc. that they can only be grown in one field for two years without depleting the soil.

Sugar beets absorb nutrients from the soil faster than almost any other crop and, as a result, this yeast is exceptionally rich in Selenium, Chromium, Potassium, Magnesium, Sodium, Copper, Manganese, Iron, Zinc and other factors natural to yeast.

Lewis Laboratories' 100% Pure Premium Imported Brewers Yeast is the only brewer's yeast that actually tastes good! Absolutely no aftertaste. Totally digestible. It will change your idea of what brewer's yeast really is.

In today's world they, at Lewis Laboratories, are convinced that both man and animal have moved so far away from natural nutrition that every species needs proper supplementation. They are dedicated to formulating the finest products to provide this. Their products take into account the synergistic interaction between nutritional factors and the fact that each one provides the proportionate nutritional balance for maximum benefit.


No one today doubts the connection between good nutrition and good health. Yet, because nutrition is such a new science, nutrition and preventative medicine are not taught in most American medical schools. Doctors are not trained in nutrition even though scientists know nutritional deficiencies are at the root of hundreds of different illnesses and that natural resistance to disease, resulting from balanced nutrition, is the best way to stay healthy. Our doctors are trained to treat sickness, not to prevent it. In ancient China, villagers paid their doctors a regular fee to keep them healthy. If they got sick, they stopped paying until they recovered. Wouldn't it be nice if our doctors had such an incentive plan?


In our society, many people suffer from mental depression or lack of energy and stamina. They are alive but not living. In many cases, these problems can be traced and corrected by improving the nutritional balance in the diet. Until recently, what has not been fully appreciated is the inter-relationship between nutritional factors.


This is a big word. It simply means that the effect of nutrients taken together is greater than when taken separately. Not one of the nutritional factors we need each day works alone – they all interact with each other. In many cases, a single nutrient cannot be used at all in the absence of another! Interaction is essential for the body to produce the estimated 10,000 compounds it makes which are required to keep one healthy, happy and active. They are convinced that the best nutritional supplement is the most complete one.


As much as they have learned in the last few years about the science of nutrition, they believe they have only scratched the surface. There are many more mysteries in natural food than they have even yet suspected. That is why they have chosen the richest natural food sources in all their products. For example, one of the ingredients they use, wheat-germ oil, was tested on 894 subjects under controlled conditions and analyzed at the University of Illinois by Dr. Thomas K. Cureton, Ph.D. He concluded, “the results show statistically significant effects on several types of endurance performances, total body reaction times, basal metabolism and oxygen intake tests”.  They use wheat-germ oil primarily for its Vitamin E content, which is just one reason they prefer natural sources to chemical additives.

In theory, you could probably make the chemical equivalents of most of their products cheaper, and perhaps more easily, based on known nutritional factors. However, it would be a mistake to think they would be the same superior products. The natural ingredients we use are like an insurance policy against unforeseen health concerns. If you are buying fire insurance, you want insurance for any kind of fire, not just those that the experts regard as important.

The human body is a fantastic machine with incredible resilience. All you need to do is take a little care to be sure it gets the essential nutrients it cannot synthesize for itself. There is probably nothing more rewarding you can do for yourself than to make the effort to develop your own special program for better health with the superior, high quality supplements from Lewis Laboratories International, Ltd.

Take 3 rounded tablespoons daily. It dissolves easily in milk, juice, soup, yogurt, or you may spinkle it over popcorn. Its unsurpassed taste means you can sprinkle it on salad, cottage cheese and other foods.

Can be refrigerated in original container. Do not allow moisture in product.
