While EPXBody makes some bold claims, I think that it's more important to look at their product, before analyzing a statement that they made that isn't necessarily a large part of what they are selling. EPXBody sells four products: EPXBody Burn, EPXBody Cardio, EPXBody Restore, and EPXBody Nourish. These products come in various forms, and are meant to do different things for your body and health.
EPXBody Burn is marketed as a weight loss pill, and is supposed to help suppress your appetite, making you want to eat smaller portions of food, and also increase your energy to help you start your weight loss program. EPXBody also claims that the Burn pill speeds weight loss, burns your belly fat, and generally increases your health. EPXBody Burn is composed of some fairly simple and common ingredients, such as green tea extract, black pepper, cayenne pepper, and vitamins C and B6. Studies have shown that groups taking one of the main ingredients in EPXBody Burn, Irvingia Gabonensis, which comes from African mangoes, lost an average of 28 pounds over a 10-week period. One of these studies was also featured on FOX news, titled "Exotic Fruit Extract May Shed Pounds, Lower Cholesterol." All of the studies seem very credible, although I am still a supporter of simply watching what you eat and working out as a "weight loss plan", rather than spending your money on weight loss pills.
The EPXBody Cardio drink mix is meant to increase your cardiovascular health, and help prevent heart disease by supplying your body with L-Arginine and L-Citrulline. L-Arginine has been proven to help increase blood flow, which in turn reduces stress on your heart and lowers blood pressure. L-Citrulline aids your body in producing more L-Arginine and boosts your energy. EPXBody claims that their Cardio mix can do a long list of things for your body, including promoting sexual function, libido, AND performance. However, many of the things included on their list of effects seem like effects that can't exactly be proven nor disproven, such as "Increases energy levels to a more youthful state." or "Speeds recovery time after surgery and decreases infections." EPXBody Cardio is still a legitimate product, and if people taking it believe that it works, then it works for them.
The main idea of the EPXBody Restore spray is that it contains "Adaptogens", a chemical taken from plants that is meant to reduce fatigue, increase physical and mental capacity, and improve lifespan. Legitimate studies done by Russian scientist Dr. Isreal Brekhman showed the effectiveness of adaptogens in helping the body adapt and cope with daily changes. The EPXBody spray also boasts a long list of effects, one of which is also "Increased sexual vitality." Similar to the EPXBody Cardio product, I feel that if the person taking it really thinks it is working, it will probably work, whether as a placebo or because its ingredients actually have a positive effect on the body.
EPXBody Nourish comes in the form of a meal-replacement shake, and contains Whey and Casein protein, as well as fats, carbs, and fibers. EPXBody Nourish is meant to improve muscle performance in the body, and also decrease muscle recovery time. Once again, a legitimate product, and one that I can see being the most beneficial to someone trying to stay in shape, given its protein and fiber content.
EPXBody is a legitimate company with legitimate products to sell. Whether or not these products work is up to the consumer, and I have never used any of the products so I can't say myself whether or not they work, although the studies that are included on the page for each product show that they do.
As for the epigenetics statement, epigenetics is a legitimate area of science. The point of epigenetics is not to "change" one's DNA or genes, but simply to change the way that the genes express themselves in the body. Epigenetics shows that environmental stimuli and even foods that create methyl groups within the body can alter gene expression, especially in the early stages of development. A good diet CAN alter your gene expression and that of your offspring, but there is no proof to support EPXBody's claim that their products will make you and the generations that follow you healthier.
