Stimerex-ES® dietary supplement promises to be the strongest ephedra based product available over-the-counter, without a prescription. Stimerex-ES® includes nutrients derived from herbs and botanicals that may help increase energy and promote weight loss. Its key ingredients include Sida cordifolia extract (ephedra), Theobroma cocoa extract phenylethylamine HCl, Citrus aurantium extract/synephrine, green tea extract, yohimbe extract (bark), naringen, and caffeine.
In 2004, the Food and Drug Administration (FDA) banned the sale of the herbal supplement ephedra. However, the ban was recently challenged by a supplement company, Nutraceutical International Corp. On April 14, 2005, Judge Tena Campbell of the U.S. District in Salt Lake City, Utah subsequently agreed with the supplement company and struck down the ban. The judge stated that the law requires the FDA to prove that ephedra is harmful. "The [FDA's] statement that a safe level cannot be determined is simply not sufficient to meet the government's burden," wrote Judge Campbell. The FDA is determining their next step.
Ephedra is most commonly extracted from the herbs Ma Huang (Ephedra sinica) and Country Mallow (Sida cordifolia). Research has shown that ephedra, an amphetamine-like herb, is an effective thermogenic (calorie burner). However, ephredra also has dangerous side effects such as heart palpitations, blood vessel constriction, and adrenal fatigue. Ephedra is especially risky for people with heart disease or high blood pressure or who participate in heavy exercise. Furthermore, ephedra overuse and abuse has been linked to dozens of deaths.
The manufacturer, Nutra Source, has not conducted clinical studies of Stimerex-ES®. However, research has shown that the combination of ephedra and caffeine works synergistically for a thermogenic and stimulant effect. Citrus aurantium/synephrine has milder thermogenic and stimulant effects and helps promote weight loss. In addition, theobroma (derived from cocoa) may have a positive effect on mood. Green tea extract has been found to modestly elevate the metabolic rate. Naringen is a citrus flavonoid that may enhance the absorption of supplements in the body.
The U.S. Food and Drug Administration (FDA) has warned that yohimbe (an African tree bark extract), used as an aphrodisiac, is associated with potentially harmful side effects. "Serious adverse effects including renal failure, seizures and death, have been reported to FDA with products containing yohimbe and are currently under investigation," states the FDA.
