Overview

GNC Mega Men Sport is a multivitamin supplement formulated for active men. It provides a comprehensive blend of vitamins and minerals, some at very high doses, intended to support energy levels, muscle protein synthesis, and overall well-being. The inclusion of branched-chain amino acids and a creatine precursor blend are likely underdosed and of limited benefit. The proprietary blend makes it difficult to determine if the ingredients are adequately dosed for their intended purposes.

The Good

Comprehensive blend of essential vitamins and minerals to support energy levels and carbohydrate metabolism.

High doses of B vitamins may support energy production and nervous system function.

Includes antioxidants such as Vitamin C, Vitamin E, Selenium, Lutein and Lycopene which may help protect cells from damage.

The Bad

Branched Chain Amino Acid Blend at ineffective dosage.

Creatine Precursor Blend at ineffective dosage.

Proprietary blends obscure ingredient dosages, limiting assessment of effectiveness.

Is it for you?

Best For: Active men, athletes, fitness enthusiasts, individuals seeking comprehensive nutritional support

Skip If: You have a pre-existing medical condition, are taking medication, or are sensitive to stimulants.
