Protandim

Protandim is a patented dietary supplement marketed by LifeVantage Corporation (OTCBB: LFVN; formerly LifeLine Therapeutics and Yaak River Resources, Inc), a Utah-based multilevel marketing company.[1] The manufacturers of Protandim claim the product can indirectly increase antioxidant activity by upregulating endogenous antioxidant factors such as the enzymes superoxide dismutase (SOD) and catalase, as well as the tripeptide glutathione, and by activation of Nrf2. Like all dietary supplements, Protandim has not been evaluated by the U.S. Food and Drug Administration (FDA) and "is not intended to diagnose, treat, cure, or prevent any disease." [2]

Protandim Composition

Protandim was invented by Paul R. Myhill and William J. Driscoll.[3] and is produced under a manufacturing agreement with The Chemins Company of Colorado Springs, Colorado.[4] The product consists mainly of a blend of 5 ingredients (amounts per caplet listed in parentheses):

Additional ingredients include: calcium, croscarmellose sodium, magnesium stearate, microcrystalline cellulose, modified cellulose, silica, and stearic acid.

Protandim Side Effects

According to the manufacturer, the side effects of Protandim may include allergic responses, gastrointestinal disturbances (stomach ache, diarrhea, vomiting), headache, and rash of the hands and feet.[5]

Research

Eight research studies of Protandim have been published as of 2011; all but one[6] were conducted in in vitro or in vivo animal models. Five of the studies were conducted, written, and/or funded in whole or in part by LifeVantage and its predecessor Lifeline Therapeutics.[6][7][8][9][10] One of these studies, a non-randomized, non-controlled trial in human subjects, reported that Protandim increased the levels of the antioxidant enzymes SOD and catalase while reducing TBAR levels.[6][11] The second study, conducted in isolated cells in vitro, demonstrated that Protandim increased glutathione levels.[7]

Subsequent research published by LifeVantage executive Joe McCord and colleagues at Louisiana State University indicated that intraperitoneal injection of an alcohol-based extract of Protandim could suppress skin tumor incidence in an experimental model in mice[8][12] and result in suppression of p53 and induction of MnSOD in isolated mouse epidermal cells in vitro.[12]

Another study conducted by Dr. McCord and associates investigated the effect of intraperitoneal injection of an alcohol-based extract of Protandim in an experimental model of pulmonary hypertension in rats. It was reported that the extract induced myocardial nuclear factor E2-related factor 2 and heme oxygenase 1, prevented a loss of myocardial capillaries, minimized fibrosis and preserved RV function [13]

Other studies by McCord and colleagues have examined the effects of Protandim on fibrosis in a rodent model of Duchenne muscular dystrophy (DMD)[9] and the effects of an alcohol extract of Protandim in an in vitro saphenous vein graft model.[14] In a study investigating the effects of various agents on skeletal muscle tissue function in an in vitro model of DMD, compounds used clinically for DMD treatment, such as the glucocorticoids, were found to produce a potentially beneficial increase in muscular contractile force, while Protandim produced the opposite effect, significantly inhibiting contractile force.[15]

Lifevantage advertises Protandim as a Nrf2 activator.[16] A 2003 study showed that Nrf2 and heme oxygenase 1 are induced by low doses of curcumin (one of the principal ingredients in Protandim) in isolated kidney epithelial cells.[17]

A 2008 review article noted that Protandim is one of many supplements that claim to act as antioxidants, but that changes in TBARS levels and increases in the levels of antioxidant enzymes in response to a treatment do not provide a reliable indication that the treatment has an antioxidant effect, since the same responses are produced by pro-oxidant compounds that induce oxidative stress. The authors suggested that measurement of isoprostanes might be a better indication of lipid peroxidation and oxidative damage to DNA.[18]

A review by Science-Based Medicine of eight peer-reviewed studies found insufficient evidence to support its usefulness. Dr. Harriet Hall states, "We simply don’t know enough at this point to recommend Protandim for treatment or prevention of any disease, for anti-aging, for making people feel healthier or more energetic, or for anything else."[19]

Legal Issues

In 2009, LifeVantage was sued by Utah-based Zrii LLC, a marketer of nutritional fruit drinks endorsed by Deepak Chopra, based on allegations that LifeVantage had conspired with former Zrii executives to “ruin the company” and take it over “on the cheap” following a “mass exodus” of Zrii distributors to LifeVantage. The case was closed in December 2009 following LifeVantage’s settlement payment of $400,000 to Zrii.[20]

On October 14, 2011, Burke Hedges, a former high-level LifeVantage distributor, filed a lawsuit with the Utah District Court against LifeVantage and its executives, seeking $3 million in punitive damages over allegations of wrongful termination and tortuous interference.[21]

Advertising and Sponsorship

On September 15, 2011, LifeVantage entered into an agreement with entertainer Donny Osmond to act as a spokesperson for the company’s products. The 2-year contract stipulates that the company will pay Osmond for various promotional appearances and video recordings and commissions for sales of LifeVantage products.[22]
