What’s GNC Mega Men Energy & Metabolism?

According to the packaging, GNC Mega Men Energy & Metabolism is a, “clinically studied multivitamin.” It also claims that it, “helps support colon and prostate health…improve[s] levels of key B vitamins essential for energy production…contains a combination of thermogenic ingredients that may support calorie burning and mental sharpness…[and] help[s] fight free radicals that can be produced during intense exercise.”

They also claim to be “clinically studied” and “physician endorsed”. However, when you read the fine print, the truth behind these claims is revealed. GNC provides the same study for all of their products for women, men, and children. We could not find where this research was done, as it is not published anywhere but on their website. Additionally, there is no specific information on what “GNC vitamin and mineral blend” was tested, making this product seem a bit sketchy.

As for their “physician endorsed” stamp, this means that the product is endorsed by a GNC Medical Advisory Board, not any doctors that are not affiliated with the company.

Potential GNC Mega Men Energy & Metabolism Side Effects

For multivitamin containing only natural ingredients, primarily vitamins, it seems like many people are seeing negative effects. According to customer reviews, GNC Mega Men Energy & Metabolism side effects may include:

  • Jitters
  • Accelerated heart rate
  • Shortness of breath
  • Nausea
  • Stomachache
  • Headache
  • Insomnia
  • Muscle fatigue
  • Dizziness
  • Hives

What’s the Final Take on GNC Mega Men Energy & Metabolism?

So, what’s the deal with GNC Mega Men Energy & Metabolism? Well, the outlook doesn’t seem very good. The science offered on their website is not found anywhere else and the same information is used for all of their products, which can be misleading. Their physician’s stamp is provided by a GNC Medical Board as well, which are basically doctors who are paid by the company for their recommendation, which is not exactly honest. Additionally, this “multivitamin” seems to have a lot of side effects, something we really don’t like. We are quite skeptical about this one.
