Metabolife 356 is one of the most well-known diet supplements on the market. It is used worldwide by millions of dieters. In the past 15 years, the Federal Drug Administration has documented well over 800 claims of health problems, ranging from moderate to severe, due to its use and misuse.
Metabolife is one of the few weight loss products that uses both ephedra and guarana. Great care must be exercised when combining these two strong stimulants. In some cases when stimulants (or any other similar supplements) are combined, they may counteract each other. These two do not and actually work to enhance each other's effects. For the wrong person, this could be a deadly combination. Because of this potent mixture, Metabolife 356 should only be used under the strict supervision of a qualified professional or physician.
Ephedra
Ephedra is widely used in the sports world to increase the uptake of oxygen and help to maintain increased heart rate during workouts. It is also used by people with respiratory problems such as asthma and chronic sinus problems. It works by raising the heart rate and moving oxygen-saturated blood throughout the body at a faster pace.
Guarana
Guarana contains a substance that is chemically identical to caffeine. Guaranine causes the same basic side effects as caffeine. Guarana originates in South America near Brazil and is used for bowel problems as well as a natural way to build strength and stamina.
Seizures
When combined, guarana and ephedrine can have a dramatic effect on the chemical balance of the brain. By increasing the heart rate and blood pressure rate and providing extra amounts of oxygen, you also raise other chemical levels and the byproducts of their reactions. This can be overwhelming to the brain and, in some cases, cause mild to moderate seizures. Even though Metabolife 356 contains other ingredients, such as vitamins and amino acids that help to balance out some of the harsher effects, its use should still be monitored.
Elevated Blood Pressure
Because of the effects on the heart and its ability to increase pulse rates, it also will elevate the body's blood pressure. It's because of these reactions that athletes should be carefully monitored when using either ephedra or guarana during sporting events or workouts. In the past, athletes who have misused the substances have died. Dieters who misuse Metabolife to try and lose weight at a faster-than-suggested rate also may be at risk.
