Meal Replacement

For weight reduction & maintenance
of healthy weight as part of an energy
reduced diet.

One serving provides 100% of the daily amount of soy protein shown to help reduce cholesterol, a risk factor for heart disease



Health Canada's Food Directorate Conclusion

The evidence consistently supports a direction of effect towards a reduction in total and LDL cholesterol levels when soy protein is consumed. A meta-analysis showed a statistically significant reduction in total and LDL cholesterol levels with soy protein consumption and no detrimental effect on HDL cholesterol and triglyceride levels.

Health Canada’s Food Directorate has concluded that scientific evidence exists to support a claim about soy protein and blood cholesterol lowering. The claim is relevant and generally applicable to the Canadian population on the basis that 39% of Canadians aged 6 to 79 years had unhealthy levels of total cholesterol (>5.2 mmol/L for adults) during the time period of 2009-2011.

The following statement may be made in the labelling and advertising of food products meeting the qualifying criteria.

Primary statement

One serving of Vitex’s Soya Slim (50 g of Soya Slim powder + 250 ml of Organic unsweetened soy milk) provides 100% of the daily amount of soy protein shown to help reduce cholesterol (which is) a risk factor for heart disease.

The “daily amount” referred to in the primary statement is 25 g of soy protein. This amount is based on the evidence available concerning the amount of soy protein shown to help reduce cholesterol.

SOYA SLIM is a premium meal replacement formula designed to help you control your weight by controlling calorie intake in a nutritionally balanced way. Most popular meal replacement formulas are usually mixtures of refined sugar (sucrose or fructose), milk protein or skim milk powder, hydrogenated oils and often with artificial sweeteners and flavors and with a few added vitamins and minerals.

SOYA SLIM is a completely balanced natural food with the ideal ratio of protein, carbohydrate, essential fats and dietary fiber, plus a complete array of essential Vitamins, Minerals and Enzymes necessary to maintain optimum health. Three servings a day to replace three traditional meals plus a snack will provide the optimum nutrition to encourage healthy weight loss. Each serving provides 244 calories for a total daily intake of 732 calories in three servings. When desired weight has been maintained, one serving per day in place of a meal will help to maintain an ideal weight.

SOYA SLIM can also be used to make a nutritious drink for athletes, children, seniors, for those who are convalescing or for those who have difficulty obtaining optimum nutrition from traditional diets. For additional calories and taste, add to the blender some fresh or frozen fruit such as a small banana or fresh or frozen strawberries or blueberries. For weight gain, add as a snack to the regular diet.


Mix 2 level scoops (50 g) (with optional ice cubes for a frothy shake) in a blender with 250 ml of organic fortified unsweetened soy milk and drink immediately. Take 3-4 times per day in place of normal meals.


Non-GMO Soy Protein isolate:

Non-GMO Soy Protein isolate is lactose and cholesterol free and contains several components including isoflavones (especially genistein), methionine, phytic acid and protease inhibitors, which help lower cholesterol levels and to lower the risk of cardiovascular disease. Animal proteins cause significant hypercholesterolimia in test subjects, while test subjects fed diets of soy protein had lower cholesterol levels. Genistein, the major soy isoflavone, also stimulates bone formation.

Non-GMO Soy Protein isolate averages 68 mg of isoflavones per 100 g of protein (varies according to growing conditions). Only 40 grams of isolated soy protein per day increases bone mineral content and density.

Women with breast cancer who consumed isoflavones in large amounts were 21 percent less likely to die than their counterparts who consumed small amounts.

In a large, 9.4-year study(2) of an ethnically diverse cohort of 6235 women with breast cancer living in North America, a higher dietary intake of isoflavones was associated with reduced all-cause mortality.

Non-GMO Soy Protein isolate has a PDCAAS (Protein Digestibility Corrected Amino Acid Score) of 1: equivalent in protein quality to milk or egg protein. It meets or exceeds the World Health Organization (WHO) Essential Amino Acid Requirements of Children and Adults.

Adequate protein is essential to support fitness training and hard physical labour. Protein requirements are based on total energy needs, body mass, type of activity, level of training, age, sex and climate, temperature, and altitude.

Isolated soy protein has been proven to enhance athletic performance, especially where endurance and/or strength are critical factors. Exercise results in an increased oxidation rate for the branched chain amino acids (leucine, isoleucine, and valine).

The anabolic effect of training is influenced by adequate levels of testosterone, growth hormone and insulin in the blood. Arginine, lysine, and ornithine may stimulate the release of testosterone, growth hormone or insulin and promote muscle development.

Non-GMO Soy Protein isolate is high in all these amino acids, surpassing casein, whey, and egg protein. Soy protein is also effective in maintaining positive nitrogen balance and normal biochemical parameters, especially important as part of a low-calorie diet for weight loss. Protein, however, is not the only macronutrient necessary for maintaining good health, and for improving athletic performance. Carbohydrates, essential fatty acids and dietary fibre also play essential roles.

SOYA SLIM provides an ideal balance between these four macronutrients. Most research indicates that dietary protein should make up between 15% and 30% of total calories, while carbohydrates should be between 50% and 70%, and polyunsaturated fats should make up between 15% and 20% of total calories (saturated fat and trans fats should be as close to 0 as possible). Dietary fibre should be at least 12.5 grams per 1,000 calories per day.

Dextrose Monohydrate (Non-GMO):

SOYA SLIM contains dextrose monohydrate, (d-glucose the natural form which occurs in nature Glucose is the body's most important energy providing molecule; a clean burning fuel for all life functions that require energy, from molecular biochemistry to athletic activity. The blood continuously delivers glucose to all tissues. Glucose is the active transporter that moves creatine into muscle tissue. The brain, nervous system, and eye use glucose almost exclusively for their energy requirements. A brain shortage of glucose results in behavioral symptoms (hypoglycemia) or low blood sugar. Whatever glucose the body cannot immediately use is stored as glycogen or fat, then tapped, and recycled as glucose whenever needed. Like protein and essential fats, glucose is an essential nutrient upon which life depends.

Erythritol (Organic):

SOYA SLIM contains Erythritol, a sugar alcohol (or polyol) that occurs naturally in some fruit and fermented foods. It is produced from glucose by fermentation with a yeast; Moniliella pollinis. Erythritol is 60–70% as sweet as sucrose (table sugar), yet it is almost non-caloric, does not affect blood sugar, does not cause tooth decay, is partially absorbed by the body and is excreted in urine and feces. It has a caloric value of 0.2 kilocalories per gram (95% less than sugar).

Erythritol has been known for a long time and its beneficial effects on caries prevention and the potential health benefits in diabetic patients have been demonstrated in several studies. Glucagon-like peptide-1 (GLP-1) and cholecystokinin (CCK) are released from the gut in response to food intake, promoting satiation, reducing gastric emptying (GE), and modulating glucose homeostasis.

Glucose ingestion stimulates sweet taste receptors in the gut and leads to incretin and gastrointestinal hormone release. In a study(1), ten lean and 10 obese volunteers were given 75 g of glucose, 50 g of xylitol, or 75 g of erythritol in 300 ml of water or placebo (water) by a nasogastric tube. Plasma glucose, insulin, active GLP-1, CCK, and GE with a [(13) C] sodium acetate breath test and assessed subjective feelings of satiation were examined. Both xylitol and erythritol induced a significant retardation in GE. Subjective feelings of appetite were not significantly different after carbohydrate intake compared with placebo.

Many meal replacement formulas replace sucrose or fructose with artificial sweeteners such as sucralose or aspartame to reduce calories to encourage weight loss while maintaining a sweet taste. Recent research(3) however warns of concerns for people with pre-existing high blood glucose as scientific evidence show that sucralose promotes metabolic dysfunction. The increase in transportation of glucose into cells may be of concern for adults who have prediabetes or diabetes and among adults who are obese. Also, new research(4) suggests that aspartame may be ineffective for weight loss, and it may even have the opposite effect by making you hungrier and lead to weight gain.

In conclusion, acute ingestion of erythritol stimulates gut hormone release and slows down gastric emptying, whereas there is negligible effect on insulin release. This has beneficial effects in a meal replacement formula such as Soya Slim as it helps to control appetite and compliance, which is especially helpful to diabetics without the concerns of artificial sweeteners such as sucralose or aspartame.

Soy Lecithin (non-GMO):

Lecithin is a phospholipid composed of glycerol, two fatty acids and a Phosphatidic Acid. The primary phosphatides are Phosphatidyle Ethanolamine (PE) and Phosphatidyl Choline (PC). Lecithin is the dietary precursor of acetylcholine, a neurotransmitter required for normal brain function. PC functions structurally as a component of the cell membrane. PC also occurs in plasma lipo-protein complexes where it assists in the transport of lipids throughout the bloodstream. In the bile, PC acts as an emulsifier while aiding in fat transport from the gastrointestinal tract.

SOYA SLIM contains a special oil free powdered lecithin from non GMO soy beans containing 97% phosphatides. Each 50 g serving contains 1150 mg of phosphatidyl choline, a powerful fat emulsifying compound that is present in every cell in the body. PC solubilises fats and cholesterol in the blood stream, solubilises dietary fats in the intestinal mucosa and maintains structural integrity of cell membranes. PC is a source of choline, a B-complex factor with powerful lipotropic activity that plays a vital role in brain neurotransmission. Lecithin also provides linoleic acid, an omega 6 essential fatty acid which is the precursor to the series l Prostaglandins, hormone like substances that regulate the synthesis of cyclic AMP (adenosine 3',5'-cyclic monophosphate), which in turn regulates hormone, protein, bone, fatty acid, amino acid, glycogen, nerve and energy metabolism. Physical activity plays a central role in the control of lipid metabolism. Increased physical activity induces a number of positive changes in the metabolism of lipoproteins: serum triglycerides are lowered by the increased lipolytic activity and the production of native high density lipoprotein (HDL) particles is increased. With increased lecithin, cholesterol acytl-transferase activity leads to increased production of HDL2, which is catabolised more slowly due to a decreased activity of hepatic lipase. These three effects explain the increased HDL levels of endurance trained individuals.

Inulin (non-GMO):

SOYA SLIM contains inulin, a 100% natural fibre from the chicory root. Inulin has unusually adaptable characteristics: Its flavour ranges from bland to subtly sweet (approx. 10% sweetness of sugar/sucrose). It can be used to replace sugar, fat and flour. This is advantageous because inulin contains 25-35% of the food energy of carbohydrates (starch & sugar). Inulin also has health benefits; it increases calcium absorption and possibly magnesium absorption while promoting the growth of intestinal bacteria. In terms of nutrition, it is considered a form of soluble fibre and is sometimes categorized as a prebiotic. Due to the body's limited ability to process fructans, inulin has minimal impact on blood sugar and unlike fructose, is not insulemic and does not raise triglycerides making it suitable for diabetics and potentially helpful in managing blood sugar-related illnesses. The mechanism of action of Inulin relates to the ability of dietary fibre to increase the viscosity of the gastrointestinal contents, promoting bowel activity, but slowing the emptying of the stomach. Inulin inhibits micelle formation in the intestines: By altering the balance in the intestinal flora of the beneficial organisms, Inulin helps build the disease resistance of the host.

Xanthan Gum (non-GMO):

SOYA SLIM contains xanthan gum, an extracellular polysaccharide produced by the bacterium Xanthomonas Campestris. This gum is highly edible and is a good source of dietary fibre. It has the ability to form mixed gels with certain other polysaccharides such as inulin. Like inulin, xanthan gum increases intestinal transit time, absorbs faecal water, influences glucose and lipid metabolism, mineral absorption, reduces the risk of colon cancer and helps protect against obesity, diabetes mellitus, coronary heart disease and hyper-cholesterolemia. Xanthan gum enhances mouth feel, and gives SOYA SLIM a smooth texture and great taste.

Soy Isoflavones - Estrogenic And Anti-Estrogenic Activities

SOYA SLIM contains contains 34 mg of isoflavones per 50 gram serving and unsweetened Soy Milk contains 16 mg per 250 ml serving for a total of 50 mg per serving, or 150 mg per day with 3 servings.

Soy isoflavones are known to have weak estrogenic or hormone-like activity. Estrogens are signaling molecules that exert their effects by binding to estrogen receptors within cells. The estrogen-receptor complex interacts with DNA to change the expression of estrogen-responsive genes. Estrogen receptors are present in numerous tissues other than those associated with reproduction, including bone, liver, heart, and brain. Soy isoflavones and other phytoestrogens can bind to estrogen receptors, mimicking the effects of estrogen in some tissues and antagonizing (blocking) the effects of estrogen in others. Scientists are interested in the tissue-selective activities of phytoestrogens because anti-estrogenic effects in reproductive tissue could help reduce the risk of hormone-associated cancers (breast, uterine, and prostate), while estrogenic effects in other tissues could help maintain bone density and improve blood lipid profiles (cholesterol levels). The extent to which soy isoflavones exert estrogenic and anti-estrogenic effects in humans is currently the focus of considerable scientific research.

Soy Protein Helps Men With Diabetes Mellitus

A randomized controlled study published October 31, 2016 in the Journal of Clinical Endocrinology & Metabolism, showed that daily consumption of 40 grams of soy protein containing 6.6 mg of isoflavones for three months (two servings daily of SOYA SLIM with soy milk contains 52 g of soy protein with 8.6 mg of isoflavones) helps men with diabetes mellitus reduce their cardiovascular risk and increases thyroid-stimulating hormone (HSH) and reduces free thyroxine (FT4) which improves their thyroidal function.


Low levels of HSH and high levels of FT4 indicate subclinical or clinical hypothyroidism which can worsen the diabetic condition.

Supplementation with soy protein with isoflavones significantly reduces HbA1c and HOMA-IR and triglycerides, CRP and diastolic blood pressure reducing cardiovascular risk. Soy protein does not affect either total testosterone or absolute free testosterone levels in men with diabetes mellitus.

Vitamins and Minerals:

SOYA SLIM is fortified with a complete complement of vitamins, minerals and enzymes based on the Suggested Optimal Nutrient Allowance (SONA) study, equivalent to one tablet of SOURCE Optimum per 50 g serving, and meeting Health Canada’s Proposed Revisions for the Nutrient Composition of Meal Replacements (07/2005). SOYA SLIM contains all the mandatory nutrients as well as all the optional nutrients at maximum allowable values.

Control your appetite:

SOYA SLIM's unique formula contains premium quality non-GMO soy protein isolate, which makes you feel full and satisfied so you can manage your food intake without feeling hungry: Organic erythritol which stimulates gut hormone release and slows down gastric emptying, and Inulin fibre which provides a lasting sense of fullness so you are less likely to over-eat.
