Detox FORMULA Healthcare Professionals Product Guide Formulated to help support the liver * Scientifically Tested for Safety and Efficacy. This is an educational publication provided to help licensed healthcare professionals understand the science upon which Detox Formula is based and the mechanism of action by which Detox Formula works. This guide should not be used to sell Detox Formula and is intended for healthcare professionals only. The only claims that can be made for Detox Formula are those that have been approved by the Company. A Scientific Product Review COMPREHENSIVE MULTI NUTRIENT SUPPLEMENT FOR LIVER DETOXIFICATION * A Scientific Product Review by Josh Zhu, M.D., Ph.D. and Michael Chang, Ph.D. * These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.

Detox FORMULA For Liver Detoxification * Summary Pharmanex Detox Formula is a proprietary blend of nutrients to help support the liver the body s detoxifying organ. A proprietary blend of patented D-glucarate, milk thistle extract, N-acetyl-L-cysteine and vitamin C promotes the neutralization and elimination of toxic metabolites and foreign chemicals in the liver. Each of these ingredients has been shown individually to support normal liver health, liver detoxification, bile flow, and glutathione synthesis. Detox Formula provides scientifically supported levels of active ingredients standardized for optimal results. Detox Formula is recommended to be taken on a daily basis and is intended for individuals who desire to provide dietary support for normal liver function. * Liver Detoxification Toxicity is a state of excessive concentration of harmful agents in the body. Your body defends itself from toxicity by detoxifying harmful substances that are made in the body, that invade our environment, or that are found in our diet. The liver performs many important functions including detoxification of blood, carbohydrate and lipid metabolism, protein synthesis, and secretion of bile. The products of digestion that are absorbed into the blood capillaries do not directly enter general circulation. Instead, this blood is first delivered to the liver for metabolism and detoxification. Many of these substances must be detoxified by the liver in order to become inactive and be excreted from the body. These toxic metabolites and foreign chemicals can be produced endogenously as byproducts of normal metabolism, or can be ingested in pharmaceutical drugs, nicotine, industrial and environmental chemicals, food additives or cooking byproducts (nitrates, polycyclic aromatic hydrocarbons), and alcohol. Many of the substances that must be modified by the liver are fat-soluble nonpolar compounds that must be converted into watersoluble compounds to be excreted. Water-soluble derivatives of these toxic metabolites and foreign chemicals are less biologically active and, because of their increased water solubility, are more easily excreted by the kidneys into the urine (Fox SI, 1993). Phase I Detoxification The first phase of detoxification chemically alters the composition of toxic metabolites or foreign chemicals through the cytochrome P450 monooxygenase system. Cytochrome p450 (CYP) enzymes are found in most tissues but are predominantly found in the liver (Guengerich FP, 1988). According to Hardman, humans have 12 genetically determined cytochrome P450 enzyme families, of which three, the CYP1, CYP2, and CYP3 families are involved with most drug transformations (1996). The P450 enzymes are involved in hydroxylation reactions (addition of OH- groups) that result in increased solubility in metabolism and excretion of toxic compounds. In most cases, these compounds are made inactive and are readily excreted, primarily via the kidneys (urine), and also via the gut (bile). However, this process occasionally leads to either formation of the active substance or formation of even more toxic metabolites (Guengerich FP, 1988). Phase II Detoxification Many substances require additional detoxification after phase I to become inactivated and excreted. During phase II detoxification, drugs and toxins are conjugated with (attached to) a polar group via seven different pathways leading to a water-soluble compound that can be excreted. These pathways include conjugation with glutathione, acetate, glucuronic acid, sulfate, or amino acids. Most of these toxins undergo conjugation via glucuronidation (Shils ME, 1999, Hardman JG, 1996). Glucuronidation uses the oxidation of glucuronic acid to generate three metabolites: D-glucaric acid, D-glucaro-6,3-lactone, and D-glucaro-1,4-lactone. These compounds promote the binding and removal of harmful substances during phase II detoxification. As discussed by Walaszek, Detoxification of toxins and foreign substances is not only restricted to the rate of conjugation, but also to the rate of glucuronidation reversal by beta glucuronidase (1990). Beta glucuronidase is an enzyme that has the capacity to prevent or reverse glucuronidation. The role of glucuronidation and beta glucuronidase in the body is very clear in the scientific literature (Walaszek Z, 1990). Once a toxin is conjugated, it can be taken to the kidneys or gut for excretion. Beta glucuronidase is able to reverse the conjugation in the gut, allowing the toxin to be reabsorbed and circulate through the blood stream again. This reversal process can result in re-circulation of toxins and foreign substances in an active form, which must be re-directed through liver detoxification before they can be excreted. 1 * These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.

Liver Glutathione Glutathione is the liver s most important antioxidant for both phase I and II detoxification pathways. Phase I detoxification enzymes also rely on liver glutathione as a cofactor and can deplete the supply of liver glutathione to the point that there is not enough left for phase II detoxification. It is essential to have enough liver glutathione reserves to enable detoxification of toxic metabolites and foreign chemicals to complete detoxification by phase II enzymes. An adequate supply of glutathione (GSH) is necessary for the formation of glutathione S-transferase (GST), which catalyzes the conjugation of glutathione to water-soluble substances produced from cytochrome p450 activity. These transformed metabolites are rendered less toxic and more soluble for excretion (Casseaud LF, 1979). Common Limiting Factors There are two phases of liver detoxification, as described below. Liver enzyme activity, nutrient availability, and differences in enzyme expression due to genetics, disease, and age can affect liver detoxification. According to Shils (1999), there are large genetic differences in detoxification in individuals, and this is supported by the observed individual differences in metabolism for many drugs. Phase II detoxification may be inhibited by the lack of necessary cofactors or substrates; this lack may often be attributed to the diet. The substrates needed for detoxification include a sufficient energy source, protein, fatty acids, iron, glucose, sulfur-containing amino acids, and glutathione. With aging, decreases in liver blood flow and liver mass contribute to a decline in detoxification capacity with a corresponding increase in circulating active drug levels. The decrease in phase I detoxification is more commonly affected than that in phase II (Shils ME, 1999). Primary Active Constiuents Detox Formula provides a proprietary blend of calcium D-glucarate, milk thistle extract, N-acetyl-L-cysteine and vitamin C. Calcium D-glucarate provides glucaric acid in a salt form chemically bound to calcium. Glucaric acid is a compound produced endogenously in humans and is found in highest concentrations in grapefruit, apples, oranges, and cruciferous vegetables (Walaszek Z, 1997). Calcium D-glucarate has been shown to be converted to and provide a sustained release of D-glucaro-1,4 lactone (Wattenberg LW, 1992, Walaszek Z, 1997). * Milk thistle fruit consists of ripe seed of Silybum marianum (L.) Gaertner [Fam. Asteraceae]. Milk thistle seeds contain a variety of chemical components that contribute to its liver protective activity, including flavonoids, flavonolignans, and others. Milk thistle seeds contain flavonoids such as dehydrokaempferol, quercetin, and taxifolin (Hobbs C, 1984, Morazzoni P, 1995); however, the primary active constituents of milk thistle are the flavonolignans, also known as silymarin, which is an entire group of active principles found only in the seeds of milk thistle. Silymarin consists of three isomers, named silybin, silydianin, and silychristin (Wagner H, 1974, Tittel G, 1997). Detox Formula provides a 30:1 milk thistle extract standardized to 80% silymarin. * N-acetyl-L-cysteine (NAC) is a specially modified form of the dietary amino acid cysteine. When taken orally, N- acetyl-l-cysteine is converted into the amino acids L-cysteine and glutathione. Detox Formula also provides vitamin C as calcium ascorbate, a well-tolerated and bioavailable form of buffered vitamin C. Vitamin C has also been shown to promote glutathione levels in the liver * (Nakano H, 1995). Health Benefits Detox Formula is a proprietary blend of nutrients to help support the liver and liver detoxification by supporting both phases of liver detoxification for comprehensive protection from harmful toxins. The ingredients in Detox Formula also protect and maintain healthy liver cells, stimulate the normal growth of healthy liver cells, promote liver glutathione synthesis, and stimulate normal bile flow. These mechanisms of action address various aspects of liver health, and are described below whenever appropriate. * Calcium D-Glucarate Calcium D-glucarate supports the liver s phase II detoxification system by providing a dietary substrate for production of D-glucaro-1,4 lactone. Calcium D-glucarate (as D-glucaro-1,4 lactone) is able to bind to beta glucuronidase, which inhibits the enzyme from binding to the toxins, allowing the conjugated toxin to be excreted from the body (Wattenberg LW, 1992). A review published in the August 2002 issue of Alternative Medicine Review discusses research demonstrating that short and long-term supplementation in animals with calcium D-glucarate can inhibit as much as 70 percent of beta glucuronidase s activity (Altern Med Rev, 2002, Dwivedi C, 1990). D-glucarate metabolites have been identified and shown to inhibit beta glucuronidase s activity in key organs such as the liver, gastrointestinal tract (small & large intestines, microflora), lungs, * These statements have not been evaluated by the Food and Drug Administration.

and the blood (Dwivedi C, 1990). In another study, Walaszek identified that calcium D-glucarate has been shown to be absorbed and utilized by the body and is held in the liver and gastrointestinal tract three to four times higher than the blood (Walaszek Z, 1997). Calcium D-glucarate has been studied for over 30 years and has been used in animal and in-vitro studies to show significant effects against toxic metabolites and foreign chemicals, including polycyclic aromatic hydrocarbons, aromatic and heterocyclic amines, nitrates, steroid hormones, and fungus (Dutton GJ, 1980, Dwivedi C, 1990, Walaszek Z, 1990, Walaszek Z, 1997, Anonymous, 2002, Walaszek Z, 1988, Walaszek Z, 1986, Walaszek Z, 1990). Over 20 animal studies have been performed showing that calcium D-glucarate s powerful action protects normal cell growth and replication in the presence of these toxic metabolites and foreign chemicals (Oredipe OA, 1992, Walaszek Z, 1990, Abou-Issa H, 1998, Walaszek Z, 1986, Walaszek Z, 1988). Milk Thistle Milk thistle naturally contains the antioxidant silymarin, which helps support the liver by helping to counter the effects of pollutants, alcohol, pesticides and other toxins from our environment, diet and lifestyles. The therapeutic activity of milk thistle in liver detoxification can be attributed to multiple mechanisms of action. Key constituents in milk thistle, including silymarin, may enhance the activity of liver enzymes involved in phase I detoxification and boost liver antioxidant glutathione levels (Valenzuela A, 1985). In addition, milk thistle may also promote the stimulation of normal bile flow the liver s second line of defense against toxic chemicals. Bile manufactured by the liver acts as a carrier to effectively eliminate toxins from the body, so when bile production is inhibited, this can lead to increased retention of toxic substances (Lawrence Review, 1998). A number of studies suggest that it is the antioxidant characteristics of the silymarin-flavonolignan complex that are primarily responsible for liver-protecting activity (Lawrence Review, 1985, Valenzuela A, 1989, Werback M, 1994, Bindoli A, 1977, Carallini L, 1978, Valenzuela A, 1986, Muzes G, 1991, Locher R, 1998). Milk thistle can alter and stabilize the structure of the outer cell membrane of the hepatocytes in such a way as to prevent penetration of a toxin, and can stimulate the regenerative ability of the liver and the formation of new hepatocytes (Blumenthal M, 2000, McPartland, 1996). Several reviews of double-blind studies discuss results showing the therapeutic benefits of milk thistle silymarin in protecting the liver from toxic agents (Carallini L, 1978, Feher J, 1989, Feher J, 1990, Ferenci P, 1989, Hikino H, 1988, Bone K, 1996, Morazzoni P, 1995). Liver toxicity induced by toxic agents produce free radicals and lipid peroxidation and silymarin has been shown to fight against lipid peroxidation in liver microsomes (Bosiso E, 1992). Several studies suggest that milk thistle provides liver protective effects against hepatotoxic agents, including pharmaceutical drugs and alcohol (Hahn G, 1968, Bone K, 1996, Davila J, 1989, Fintelmann V, 1980, Grungreiff K, 1995, Kurz-Dimitrova D, 1971, Szilard S, 1988). It was shown that milk thistle could also counter metabolic changes in cases of altered hepatic functions affecting the bioavailability of aspirin (Mourelle M, 1988). An in vitro study also suggested that milk thistle has cytoprotective activity against toxicity induced by acetaminophen (Shear N, 1995). In a double-blind, placebo controlled trial, biochemical parameters for hepatic function returned to normal much sooner in the milk thistle control group compared to those given a placebo (Fintelmann V, 1980). Results of a number of investigations have shown that milk thistle may improve liver function in alcoholic patients without adverse side effects and counter alcohol-induced liver damage when administered prior to alcohol consumption (Der Marderosian A, 1988, Desplaces A, 1975, DiMario ER, 1981, Fantozzi R, 1986). Lastly, research over the past four decades in Europe has confirmed repeatedly the effectiveness of milk thistle in treating a wide array of liver conditions, with extracts of the seed being shown to protect liver cells from damage stemming from chronic and acute hepatitis (Lawrence Review, 1985, Bode JC, 1977, Foster S, 1996). N-Acetyl-L-Cysteine N-acetyl-L-cysteine boosts liver glutathione levels for both phase I enzyme activity and phase II glutathione conjugations. N-acetyl-L-cysteine is an excellent source of sulfhydryl groups and is converted in the body into metabolites capable of stimulating glutathione synthesis, promoting detoxification and acting directly as a free radical scavenger. Studies have provided evidence that multiple mechanisms contribute to N-acetyl-L-cysteine s role in liver detoxification and liver protection. These include detoxification of reactive compounds due to the antioxidant and nucleophilic properties and replenishment of liver glutathione stores (De Flora S, 1995). N-acetyl-L-cysteine and vitamin C administration have been shown to improve levels of phase I detoxification enzymes, including total CYP content (+35%) and 3 * These statements have not been evaluated by the Food and Drug Administration. This product is is not intended to to diagnose, treat, cure or or prevent any disease.

CYP3A content (+100%), in animal studies (Clarke J, 1996, Berg-Candolfi M, 1996). Results from animal studies suggest that N-acetyl-L-cysteine enhances concentrations of L-cysteine within hepatocytes providing a substrate for gone synthesis (Nakano H, 1995, Sener G, 2003). In an eight-week double blind, placebo-controlled trial, blood glutathione levels significantly increased after N-acetyl-L-cysteine administration in HIV patients. These findings suggests that N-acetyl-L-cysteine therapy could be valuable for other clinical situations in which glutathione deficiency or oxidative stress play a role in disease pathology including hepatitis, rheumatoid arthritis, liver cirrhosis, diabetes, Parkinson s disease and septic shock (De Rosa SC, 2000). Interestingly, acetaminophen poisoning causes liver damage by depleting liver glutathione; a high dose treatment course (i.e. 20 grams) of N-acetyl-L-cysteine is currently the mainstay as an acetaminophen antidote (Kelly GS, 1998). Vitamin C Vitamin C is also involved in glutathione synthesis and has also been shown to boost liver glutathione levels for phase I enzyme activity and phase II glutathione conjugations. A study by Das et al, found that administration of vitamin C in animals resulted in a remarkable improvement of glutathione, lipid peroxide, superoxide dismutase, glutathione peroxidase, and catalase (Das KK, 2001). The total liver content of P-450 enzymes has been shown to correlate with the excretion of D-glucaric acid in the urine, and is a method for evaluation of the liver s functional reserve (Hanaue H, 1993). A clinical trial found that after vitamin C administration (1 g), the excretion of urinary D-glucaric acid was significantly lower, suggesting vitamin C-induced activation by P-450 enzymes. Proprietary Processing Manufacturing standards are strictly followed to ensure the creation of natural supplements with pharmaceutical-like quality. Detox Formula provides standardized ingredients with known content and uniform consistency. All ingredients are tested for purity, and where applicable, ingredients are certified pure by microbial testing, such as tests for Salmonella, E. coli, other coliforms, Staphylococcus aureus, total plate counts, yeasts, molds and pesticide residues. Our manufacturers go through a detailed selection and certification process to assure their compliance with Good Manufacturing Practice (GMP) standards set by the Food and Drug Administration (FDA). Side Effects Detox Formula has no side effects when used as recommended. However, a mild laxative effect has been observed in occasional instances with milk thistle administration (Blumenthal M, 1998). Safety and Toxicity Detox Formula is safe when used as recommended. Calcium D-glucarate has been shown to be safe for human consumption (Walazsek Z, 1990, Heerdt AS, 1995). Studies have shown that there is no toxicity with levels of calcium D-glucarate at doses up to 10 grams per day (Slaga T, 1999). Milk thistle has been used as a food for centuries (Foster S, 1996), and in both human and animal studies, seed extracts have been shown to be devoid of significant adverse side effects (Lawrence Review, 1985, Der Marderosian A, 1988, Foster S, 1996). Long-term clinical trials on humans have not generated any evidence of toxicity or teratogenic effects (Bone K, 1996, Foster S, 1996). Administration of N-acetyl-L-cysteine at 1600 mg/day has been shown to be safe and nontoxic. The major toxicities reported were bad taste and gastrointestinal disturbances (Pendyala L, 1995). The Tolerable Upper Intake Level (UL) for adults with vitamin C is set at 2g/day; the adverse effects upon which the UL is based are osmotic diarrhea and gastrointestinal disturbances (NAS, 2000). Considerable evidence from clinical trials has revealed no pattern of adverse effects with intakes up to 10 grams/day over several months. The evidence of adverse effects of vitamin C is so nebulous that no Lower Observed Adverse Effects Level (LOAEL) can be established. The No Observed Adverse Effects Level (NOAEL) has been set at more than 1000 mg (Hathcock, 1997).
