Improves Digestion


Digestive enzymes assist in the breakdown of proteins, fats, carbohydrates, and sugars. The body can't utilize the nutrients even in healthy foods unless digestive enzymes are present to aid in the delivery of the nutrients to the bloodstream, cells, and organs. And, these nutrients are what keep the immune system and the rest of the body strong and healthy.

If the body is forced to supply the digestive enzymes needed for digestion, then it has fewer enzymes for other essential body functions. Including supplemental plant enzymes at the time food is consumed provides two important benefits. First, the plant enzymes can go to work immediately to start the digestive process. Second, the body doesn't have to take enzymes from other organs. This means that more metabolic enzymes will be available to help organs and tissues function properly.


Including enzyme supplements in a daily diet may yield these important benefits:


• Restore the body's natural enzyme supply.

• Boost energy level.

• Strengthen the immune system.

• Improve overall well-being.


Many researchers support the idea that premature aging and many of the degenerative diseases people suffer from today are a result of a lack of enzymes in critical organs and tissues. Further, the level of enzymes in young adults is much greater than older adults. This may be due to a steady diet of enzyme free foods depleting the body's enzyme supply over time.


Quadra-Zyme Plus - An Effective Solution


Quadra-Zyme Plus is a plant enzyme supplement for digesting proteins, starches, fats, fibers, sugars, and dairy foods. When taken with meals, it helps pre-digest food in the upper stomach for optimal digestion and absorption of nutrients from food. Each vegetarian capsule contains amylase, protease, cellulase, lipase, maltase, invertase (sucrase), lactase, and cellulose.

Quadra-Zyme Plus can help you restore your body's natural enzyme levels and help you maximize your energy level, feel better and give you a much better chance of staying healthy and disease-free. Quadra-Zyme Plus works in a wide range of pH environments.


Below is a list of the enzymes and their function:


Amylase - Breaks down sugars and starches.

Protease - Hydrolyzes protein to peptide and amino acids.

Cellulase - Hydrolyzes cellulose.
Lactase - Breaks down the lactose in dairy products into more soluble sugars.
Invertase - Breaks down cane and beet sugars.
Maltase - Breaks down maltose, malt, and grain sugars.

Lipase - Breaks down fats and oils.

More Information:
Suggested Dosage:
Take two to four capsules with meals, depending on the size of the meal. Can be taken between meals to help build up enzyme reserves.

Scientific Studies:
In a 2004 research project conducted by The Netherlands Organization for Applied Scientific Research, the effect of supplemental digestive enzymes was studied. The purpose of the study was to measure how well digestive enzymes digest proteins and carbohydrates and how available nutrients are to the body. This study concluded that enzyme supplements can significantly increase the degree of digestion in the lumen of the small intestine and improve availability of proteins and carbohydrates to the cells.

In a 2001 study, 260 people used enzyme supplements over seven months. The majority of the people taking enzymes reported noticeable improvement. Specifically, 235 (90%) experienced positive results, 14 (6%) reported negative results, and 11 (4%) were uncertain if any change occurred. Subjects reported significant improvements in digestion, stools/bowels, energy level, sleep patterns, weight gain or loss, foods tolerated, overall appearance, and mental skills.

Research conducted by Dr. Edward Howell, over a 50-year timeframe, showed that many of the physical problems and diseases we experience can be linked to improper digestion of food. In his research, he discovered that the saliva of young adults contain 32 times more enzymes than adults over 69 years. Dr. Howell concluded that the gradual depletion of the body's enzyme supply over time was caused by a steady diet of cooked foods. As the enzyme supply diminishes, the body becomes more susceptible to degenerative diseases and premature aging. Further research on rats revealed that rats receiving enzyme supplements had a higher level of enzymes in their body and tended to live longer than rats on enzyme-free diets.

Two other research studies (Journal of Nutrition 12:59-83, 1936 and Proceedings of the Society for Experimental Biology and Medicine 37:613-615) found that younger adults tended to have much higher enzyme levels in the urine, pancreas, and cells when compared to older adults.

Research (American Journal of Physiology 141:38-41, 1944) done on both domestic and wild animals revealed that feeding these animals a diet of heat-processed, enzyme-free food caused their pancreas gland to enlarge up to three times the normal size to handle the extra burden of the enzyme-deficient food.

Safety Information:

Do not use if a stomach or colon condition exists such as ulcers, gastritis, severe burning sensations, irritable bowel syndrome, or intestinal lining damage.  The enzyme protease can temporarily irritate the ulcerated or inflamed tissues.  We suggest using Gamma-Zyme until that condition has cleared up.

Been taking the quad for, what twenty five years now? Obviously I’ve been pleased with the way it works in my body. An athletic senior now, I think of Tim and the gang as family, and hope to continue for the years ahead.

Love love love your products!
I have taken L. Salivarius for years and recently started taking Quadra-Zyme Plus and Maximizer I feel so much better. I had a pain in my lower body no doctor could tell me what was wrong. Had my blood taken and a ultrasound and exam they still didn't see anything. I hurt for months. Since I started taking both of the enzymes I have felt better and lost weight. Which I don't need to lose weight but it made my stomach flatter. And I tried the bowel toner since I am getting older I needed it. I feel like you have saved my life and you are a God sent. Thank you R-Gardern I will forever be your customer.

Quadra-zyme Plus
I love these enzymes better because they are easier for me with a sensitive stomach. Sometimes I get gastritis or ulcers and it has never effected me poorly. This zyme is best for me. Also, the fact that you can buy it on sale, or in 12 bottles and save 40 percent helps me to continue buying it. Good deal.

None Better
Grew up eating right. No sugar cereals, white flour, candy, chips, pop. Got our dairy from the farmer-60's. Popcorn was a treat, my chiropractor student dad had us drink a lg. glass of carrot juice every night at supper. Microwaves weren't invented. Knowledge is knowing which is the best products. This is a GREAT one. People think I'm younger then I look, even smoking for 22 yrs. Which I don't advise doing.

Digestion problem solved
I cannot eat even a snack without this product. It was a thrill to be able to get off of prescribed inhibitors. No more bloating, burping, or nausea after a meal. Thanks for a great product.
