GNC Mega Men Energy & Metabolism attempts to combine a healthy multivitamin with an energy booster. There are plenty of supplements out there that make this attempt, but most fail because there is either too much or too little caffeine. Caffeine is the primary, cheap ingredient to boost energy and it’s effective at increasing metabolism, but it’s not the only proven ingredient. We found this supplement listed on GNC for $19.99; cheaper than other premium multivitamins.

Product Features

The majority of the ingredients in GNC Mega Men Energy & Metabolism are vitamins and minerals. These have no direct impact on metabolism or energy, but they do support healthy functions in the body that may impact both.

Then we hit the proprietary blends. One of the proprietary blends contains four amino acids. There are healthy functions for amino acids, but they are not effective at increasing metabolism or energy.

The ingredients that work to increase metabolism in this supplement are caffeine and green tea.

The caffeine is included in a proprietary blend with just short of 120 mg. That means there is not likely enough caffeine to increase energy or metabolism. There is only 40 mg of green tea extract – so metabolism support from the green tea is out of the question.

According to clinical studies, about 300 mg of green tea is required to boost weight loss. While we realize this supplement does not claim to boost weight loss directly, that is the implication when the product name claims metabolism support. Just 40 mg of green tea and less than 75 mg of caffeine is not enough to have any impact.

GNC MEga Men Energy & Metabolism is supposed to support a healthy metabolism and energy level. The ingredient list contains all the ingredients we expected, but it does not contain enough of either proven ingredient to have an impact on energy or metabolism. This supplement is nothing more than a great multivitamin.
