Confirmation of IsaLean Shake Safety and Quality
Isagenix products must meet rigorous standards of safety and quality.
An article in the July issue of Consumer Reports magazine has raised concerns regarding traces of heavy metals in protein drinks, which has led to questions about the quality and safety of our IsaLean Shake products.
You can rest assured that Isagenix delivers on its promise to consumers to maintain a “no compromise” quality policy with a strong safety-monitoring program for all our products. Our safety-monitoring program includes microbial, pesticides, and heavy metals testing.
The Isagenix Quality Assurance Department requires testing for heavy metals including arsenic, cadmium, lead, and mercury in all raw materials before they are used in manufacturing.
If any raw material fails to meet specifications for heavy metals it is promptly rejected by our Quality Assurance Department. Besides initial inspection of raw materials, Isagenix takes an “extra mile” step with Finished Product Safety verification through independent contract laboratories. This verification process sets a high standard for ensuring the quality of our products and providing safety to consumers.
Isagenix specifications for heavy metals in finished products are adapted from Health Canada Natural Health Product Department “Evidence for Quality of Finished Natural Health Products.” The Health Canada guidelines are more stringent in nature than U.S. Pharmacopeia and World Health Organization provisional intakes of foods.
A review of our testing on multiple lots of IsaLean Shake flavors (Rich Chocolate, French Vanilla, Natural Creamy Chocolate, Natural Creamy Vanilla) all showed that the trace levels of heavy metals in these products are well below daily limits and meet Health Canada specifications. Additionally, our review shows that amounts are still below Health Canada limits per day when consumers enjoy two or three servings daily.*
Our process for continual inspection of raw materials and analysis of finished products is an expensive enterprise. Because of the high cost, similar standards are often avoided by other dietary supplement companies. At Isagenix we believe that meeting and exceeding safety guidelines is absolutely necessary as integrity and the health of our customers, friends, and family is paramount.
*Note: Because protein requirements may vary depending on health status, please consult a healthcare professional to determine individual protein needs.

IsaLean Shake: The Power of Protein for Staying Lean, Battling Aging
Most people will experience a nearly 40 percent decrease in lean body mass and more than 100 percent increase in fat mass from age 25 to 70. However, did you know that you can reverse this trend with how much high-quality protein you consume and when you consume it daily to keep and build lean body mass with age?

New research shows that eating protein at the right times, particularly at breakfast, is primary for maintaining lean body mass with age. Combined with calorie control, it is also important for avoiding obesity. Plus, the effect of protein on muscle synthesis, satiety, and fat burning can also depend largely on the protein’s quality.
Isagenix, for one, has been advising its customers about the benefits of higher intake of quality protein for breakfast with an IsaLean® Shake and IsaPro® for more than eight years. It’s perhaps the single most important way to help people stay leaner and healthier.
Aging is associated with an increasing body fat mass while simultaneously losing lean muscle tissue. This progressive process is characterized by 3 to 8 percent reduction in lean muscle mass each decade after age 30 and can be more than 50 percent loss of tissue in those over 80 years of age.
The change to gains of more fat and loss of lean mass impacts health in a way that leads to frailty, loss of strength, and decline in function and ability to care for oneself. The loss of muscle mass with age, called sarcopenia, is estimated to lead to socioeconomic and health care spending costs exceeding $18.5 million (1).
Most people don’t know they are losing muscle. It often goes undetected by the medical field because fat gain and weight stability mask the sarcopenia (2 & 3). However, the muscle loss, like osteoporosis, reduces quality of life and increases risk of disease and mortality.
Building and maintaining muscle is the most effective way to stave off the negative impact of sarcopenia and resulting risk of chronic disease.
Protein At Breakfast and Throughout the Day
The leading factors of observed sarcopenia are insufficient protein intake along with the lack of regular exercise. Maximizing muscle protein synthesis while watching total caloric intake in a dietary plan amounts to between 25 and 30 grams of high-quality protein per meal (3).
This is contrary to the current RDA, which is woefully inadequate! The RDA does little to promote optimal health in
the elderly.
Surprisingly, 15 to 41 percent of adults have dietary protein intakes below the current RDAs, which further suggests a need to push
for higher intakes of protein (4).
Clearly, maximal protein synthesis happens with adequate protein distribution throughout the day, starting with 25 to 30 grams of protein at breakfast (3). Protein at breakfast helps people stay stronger and leaner over the course of their lifetimes.
Putting a Stop To Sarcopenia with IsaLean Shake
When it comes to manufactured foods in the marketplace, protein often takes the back seat and is often replaced with cheap carbohydrates. Protein fortification isn’t easy and usually affects flavor in a bad way.
This is where IsaLean Shake comes into the picture. It makes getting enough quality protein delicious and enjoyable. It can also be combined with IsaPro whey protein to obtain higher amounts if needed.
Not all protein is the same: There are a variety of ways to address quality such as biological value and protein digestibility corrected amino acid score. Whey protein comes out on top by these measures. Also, the concentration of branched-chain amino acids (leucine, isoleucine, valine) is crucial, especially leucine.
Leucine is a rate-limiting step for protein to trigger muscle synthesis. Whey is unique for having a naturally higher concentration of leucine versus other sources of proteins such as meat, eggs, or soy.
IsaLean Shake is key because it is a beverage with quality protein from whey, rich in branched-chain amino acids including leucine, which alone will trigger protein synthesis in muscles with or even without exercise.
The beauty of quality protein is that intake affects short-term and long-term mechanisms for body weight, beyond just muscle mass anabolism.
Quality protein taken every morning also increases satiety more than either fat or carbohydrate do, keeping people fuller longer, and inducing thermogenesis when it is 25 percent of dietary energy intake (4-9).

The bottom line: quality protein throughout the day leads to better weight management, increased muscle and anti-aging. The end result is weight loss combined with maintained muscle, and a better quality of life.

What Kind of Protein Is Best for Losing Weight?
Whey protein boosts more fat burning than either soy or casein, a new study reports.
When it comes to stimulating thermogenesis and satisfying appetite, it’s well known that dietary protein is king over carbohydrates and fats. Now, a new study confirms that and goes even further to show that what protein source you choose matters, too!
According to new research from the Nestle Research Center in Switzerland, whey protein consumed at breakfast, lunch, and dinner proved most successful than either casein or soy proteins for boosting fat burning and simultaneously reducing muscle loss.
“The present findings confirm that protein-rich test meals have a greater thermic effect than that of carbohydrate and extend these results by showing that whey protein elicits a greater thermic response than does protein composed of either casein or soy,” the scientists report in the March issue of The American Journal of Clinical Nutrition.
The scientists conducted a double-blinded, randomized, placebo-controlled study, measuring the thermic effect of meals high in whey, casein, or soy proteins, with a high carbohydrate meal as a control. They found that the total energy expenditure over 5.5 hours was greater after consuming the whey protein meal versus the other proteins and all were significantly higher than the high-carbohydrate meal (see Figure).
Mean changes in fat oxidation 5.5 hours after ingestion of the test meal. Acheson et al. 2011.
The thermic effect of food is a measurement of the amount of energy that is required for digestion and absorption and metabolism. Put simply, the act of eating and digesting both brings in calories and burns them. Eating foods with a higher thermic effect can support weight management goals, and in the case of whey protein, even promote muscle growth.
More than just a metabolic measure, the thermic effect of foods reflects the rate that fats, proteins, and carbohydrates are broken down for energy in our bodies. The researchers explained the high thermic effect of whey protein might be due to the amino acid composition. Whey is high in leucine, a branched-chain amino acid, which has been shown to stimulate muscle protein synthesis and muscle turnover.
The study tested the metabolic rate, satiety, and glucose control of 23 lean, healthy individuals following one of the meal options. Subjects were tested in a metabolic chamber measuring their basal (resting) energy expenditure. Researchers monitored the subjects for five hours to measure postprandial (after-eating) energy expenditure. All meals contained an equivalent amount of calories.
In addition to boosting fat burning potential, a protein-rich diet also resulted in a much lower postprandial glucose response than the carbohydrate control. “Whey supplements have been proposed to increase synthesis, and in the presence of increased insulin secretion, one would expect its anabolic effects to favor increased lean body mass.”
The authors proposed that increased protein synthesis is “one possible mechanism responsible for the increased thermogenesis observed after high-protein than after high-carbohydrate diets, and the rate of protein synthesis has been observed to be more rapid, two-fold greater, after the consumption of whey than after that of casein.”
On the other hand, according to the researchers, casein or soy proteins may provide greater feelings of satiety (based on subjective questionnaires) and may be more effective for blood glucose control because of a slower rate of emptying from the stomach.

Editor’s note: Isagenix uses New Zealand-sourced whey and other dairy proteins including casein in IsaLean Shake to take advantage of both fast- and slow-digesting properties to maximize muscle retention through sustained blood amino acid levels, increase thermogenesis, promote satiety, and encourage healthy weight management.

You Can Prevent Sarcopenia Lifelong
Loss of skeletal muscle mass and function with aging is calledsarcopenia. It is deadly. Sarcopenia includes loss of muscle quantity and quality, loss of motor neurons that enable muscles to contract, loss of strength and especially muscle power, and a steep decline in muscle repair and recovery. In addition, there is a progressive increase in oxidative stress, chronic inflammation, and pain.
Because muscles supply the immune system with the glutamine required to make immune cells, loss of muscle also causes a loss of immune function (1). By complex effects, including a decline of oxygen to the brain because of reduced muscle contraction, sarcopenia is also linked to death of brain cells and loss of cognition and memory with age (2). Frequently, being overweight masks the appearance of sarcopenia, and only adds to the problem.
Since 1989, when it was first measured accurately, sarcopenia has grown to epidemic proportions in the US and Canada (3-6). In otherwise healthy people over 40, it can be as high as one in every four tested. Researchers on aging generally agree that it is a self-inflicted outcome that is almost 100 percent preventable.
The Right Protein
Here are the two simple steps to prevent sarcopenia lifelong: First, you have to have sufficient high-quality protein in your diet to maintain lean muscle. Because muscle protein synthesis becomes less efficient with age, only first–class protein will do it. Numerous studies, the latest just published in theAmerican Journal of Clinical Nutrition in May 2011, show that whey protein, similar to that found inIsaLean Shake, is the best (7). It stimulates muscle protein uptake better than other proteins common in shakes.
Research shows that for people over age 40, the Recommended Dietary Allowance for protein [0.8 grams per kilogram] may not be sufficient. A controlled study found muscle was not maintained in subjects fed the RDA (8). Following this type of research since the 1990s, the Colgan Institute has recommended increased protein, especially for those who exercise regularly (which we hope is everyone). Consequently, in addition to protein in meals, we generally recommend a minimum of two protein shakes per day. Each shake should contain 20 to 25 grams of whey protein, one taken upon rising in the morning, and one within 30 minutes after working out (these are the times when the body most needs it).
The Right Exercise
The second step to maintain your muscle power for life is the right type of exercise. Sorry to say that jogging or aerobics classes will not fill the bill. Numerous comparative studies now show thatresistance exercise is the only effective way (9-11). But it has to be the right resistance exercise. Many gym programs use slow, restricted machine exercises to increase strength and muscle size. I suggest they do not work to prevent sarcopenia, because the major loss in sarcopenia is a neuromuscular loss of power. Power is strength multiplied by speed in free movements. Usual gym strength training does not increase power (12-15).
Balance exercise is a key component to preventing falls in old age.
The Colgan Power Program was developed specifically to train power in athletes, and we have since adapted it for general muscle training to inhibit the sarcopenia of aging(14). There are many factors involved, so I can mention only a couple of the most important here. To get a full explanation you can consult the book (14).
First, as you age, gravity gradually compresses your spine. Most back problems stem from that compression, not from disease. After age 30, you do not want to do a lot of resistance exercise that adds to that compression. So, our first rule for lifelong resistance training, is to do exercises that lengthen the spine while contracting the muscles. We have developed hundreds of these exercises, now used by many thousands of people worldwide.
Our program gets people into the habit of working out daily for 30 minutes, with two protein shakes, one in the morning, and one immediately after workout. Many people who have adopted this simple routine over the last two decades, are physically more robust than their peers, enjoy better health than their peers, and are measurably aging more slowly. For them sarcopenia is not an issue.
The second factor I will note is balance. As part of sarcopenia, kinaesthetic and proprioceptive senses decline, and balance and coordination decline with them. That is why the biggest risk for healthy older people is a fall. Their balance systems no longer register the falling until it is too late. With the right resistance training, with a balance component, you can prevent loss of balance lifelong (16).

How Much Protein for Blood Sugar Control?
How often have you heard the key to health is maintaining healthy blood sugar? These days, with processed foods, sugary sodas, and a nation enamored with quick-fix dieting, exposure to simple sugars is running rampant. High blood sugar can have disastrous effects on cell membranes, blood vessel lining, weight management, and even your mood.
With your health in mind, Isagenix is devoted to providing nutritious meals that deliver your body necessary sugars and carbohydrates without driving up your blood sugar. How can we do this? As new research supports, protein may be the answer when it comes to balanced nutrition and balanced blood sugar.
Eating meals with at least 20 grams of whey protein, in fact — comparable to the amount found in IsaLean Shakes and Bars—helps stave-off harmful spikes in blood sugar, a recent study reports.
Incremental blood glucose response after meals containing either glucose alone (control), or glucose plus either 5, 10 or 20 g of protein.
You may be familiar with the glycemic index—a measure of the impact that a food has on your blood glucose. Lower glycemic foods have been shown to help weight management and weight loss. This study, published in Nutrition Journal, shows that 20 grams of whey protein decreases the glycemic effect of a carbohydrate drink.
Ten healthy subjects drank either a sugary control beverage or the same beverage with an additional 5, 10 or 20 grams of whey protein. Blood glucose was measured after 15, 30, 45, 60, 90 and 120 minutes.
The researchers reported that “blood glucose concentrations were significantly reduced at 30, 45 and 60 minutes after the 20 gram protein meal when compared to the control.”
Whey protein is rapidly digested, which may help explain why it also combats spikes in blood sugar, they suggested. While any amount of whey protein seemed to favorably influence glycemic response, the researchers found that the 20 gram supplement of whey protein had the greatest ability to maintain stable blood sugar.
Whey’s enhancement of glycemic control may be explained by its ability to slow absorption of sugars or, possibly, the stimulation of insulin by the amino acid leucine. Whey protein is especially high in leucine, an amino acid that is prized for stimulating muscle growth. Insulin is like a key—it opens the door for glucose to enter cells. The authors said that leucine is “insulinogenic.”
Whey’s leucine may stimulate insulin secretion, or perhaps stimulate the production of other hormones involved in blood sugar regulation.
