What is Zantrex 3?

Zantrex 3 is an over-the-counter weight loss supplement that is manufactured by Basic Research Zoller Laboratories. The product promises rapid weight loss and extreme energy without using ephedrine. Its list of ingredients include a B-vitamin (niacin), and a mixture of herbal extracts from yerba mate, guarana, damiana, green tea, black tea, kola, schizonepeta, black pepper, rhodiola crenulata, asian ginseng, maca, and cacao. Three of these ingredients, namely yerba mate, guarana, and damiana have been found to cause a delay in gastric emptying time, thereby causing a feeling of fullness in overweight and obese individuals and resulting in weight loss. The other ingredients are believed to boost energy and help burn more calories by increasing the rate of metabolism.

Its manufacturers recommend taking two capsules with a glass of water before meals for weight loss. For energy boost, they recommend taking one to two capsules as needed and two capsules as a pre-workout supplement one hour before exercise.

A lot of reaction from the public, including health experts, have been generated over Zantrex 3 because of the potential side effects it may bring owing to its high caffeine content. No tests have been conducted on its long term effectiveness and side effects. It is being marketed as a dietary supplement but is not approved by the FDA as a weight-loss supplement. Dietary supplements, unlike pharmaceutical products, are products which do not have to be pre-approved or tested by the FDA for safety or efficacy.

Possible Side Effects

According to tests done by ConsumerLab.com LLC, an independent company that offers seals of approval for manufacturers whose products pass their tests, a daily dose of Zantrex 3 contains a huge amount of caffeine (1,223 milligrams), which could give you a bigger jolt than what you would probably get from drinking 35 cans of Coke or a dozen cups of coffee. Caffeine, a chemical found in coffee, black tea, kola, guarana, yerbe mate, and other ingredients of Zantrex 3, stimulates the central nervous system, the heart, muscles, and the brain centers that control your blood pressure. Large doses of caffeine can cause sleep problems, nervousness, restlessness, headache, anxiety, stomach irritation, nausea and vomiting, chest pain, increased heart rate, faster respiratory rates, and ringing in the ears.

Too much caffeine can also make existing health problems worsen, such as heart disease, high blood pressure, high blood sugar levels, irritable bowel syndrome, seizure disorders, and bleeding disorders. It can increase the excretion of calcium in the urine, thereby increasing your risk for weak bones (osteoporosis).

Aside from these, caffeine may interact with some drugs that you are taking such as antibiotics, antidepressants, heart medications, and other medicines used to treat seizures, ulcers, and other disorders.

Consult your doctor before using Zantrex 3 to avoid its side effects. If you are already using it, inform your doctor about it especially if you are taking certain medications.
Health experts agree that the best way to lose excess weight is to eat a healthy, low calorie diet and to engage in regular exercise.
