Mega T Green Tea supplements are promoted as antioxidants, energy-boosters and weight loss products. The Mega T company advertises that their products can burn belly fat and enable users to lose as much as twenty pounds. According to the University of Maryland Medical Center, products containing caffeine and green tea may help to improve weight loss in overweight and obese people; however, there is insufficient evidence to conclusively demonstrate these benefits. Furthermore, Mega T Green Tea pills can cause significant side effects, primarily caused by the product's high caffeine content. Consult your health care provider before using any weight-loss aid.
The National Institutes of Health warns that green tea products are addictive. Regular use of green tea can cause a person to develop a tolerance to its stimulating effects, and the person may become psychologically dependent on the product. The NIH additionally notes that green tea users experience withdrawal symptoms, such as headache and mood disturbances, after abruptly discontinuing the supplements.
Anxiety and Insomnia
Mega T Green Tea is a powerful stimulant because it contains high levels of caffeine. The NIH warns that this compound, also found in coffee and colas, may cause anxiety and insomnia. Mega T Green Tea can even lead to insomnia in breastfed infants whose mothers use the product. Avoid Mega T if you are prone to anxiety, and do not take the product within a few hours of bedtime.
Mega T's reputation as a weight loss aid may relate to its diuretic effects. According to the NIH, green tea stimulates the kidneys and increases the excretion of urine. This may lead to electrolyte imbalances, incontinence and increased visits to the restroom.
Because of its stimulating effects, Mega T may be unsafe for people with certain forms of heart disease. The NIH warns that caffeine in green tea can temporarily cause elevations in heart rate and blood pressure. Consult a health care provider before using green tea if you have a history of heart palpitations or hypertension.
The NIH notes that tannins in green tea supplements can cause or worsen constipation. Additionally, green tea products may worsen symptoms in people with pre-existing ulcers.
