Overview

The GNC Mega Men Energy & Metabolism Multivitamin provides a comprehensive mix of vitamins and minerals, many of which are at very high doses. It also contains an energy and metabolism blend with some evidence of efficacy but is hidden behind a proprietary blend. While it offers a range of nutrients, the high doses and inclusion of several unproven ingredients raise concerns about its overall effectiveness compared to a simpler multivitamin.

The Good

Provides a comprehensive blend of essential vitamins and minerals, which can help address nutrient deficiencies.

Includes a high dose of B-vitamins, which may help with energy production.

Contains antioxidants such as Vitamin C and E, which may help protect against cellular damage.

The Bad

Potential for gastrointestinal discomfort due to high vitamin and mineral doses.

Risk of interaction with certain medications, such as blood thinners and diabetes drugs.

Contains 100mg of caffeine which could lead to anxiety, insomnia, or jitters in sensitive individuals.

Is it for you?

Best For: Adult men seeking general nutritional support, energy, and metabolic health.

Skip If: You are pregnant, nursing, have a pre-existing medical condition, or are taking medication without consulting a doctor.
