Analysis

This pre-workout formula includes 60 mg of Niacinamide as part of a complex matrix for energy and focus. Along with Niacin, it provides high doses of Citrulline Malate and Beta-Alanine to support vascular flow and muscle endurance. It is designed for immediate use before training rather than as a general daily vitamin.

The Niacinamide helps support the conversion of food into energy, which is vital during heavy exercise. Because it is in a powder form, you can adjust the scoop size to match your energy needs. It also includes 250 mg of Vitamin C and 70 mcg of Vitamin B12 to further support your body's metabolic demands during physical activity.

Pros

  • Includes Citrulline and Beta-Alanine for performance
  • Niacinamide supports energy metabolism during exercise
  • Fast-acting powder format
  • Zero calories and zero carbohydrates
  • High dose of Vitamin B12 and Vitamin C

Cons

  • Very high price per serving
  • Contains artificial flavors and sweeteners
  • Niacin dose is low for specific heart health goals

Warnings

  • Beta-alanine may cause a harmless tingling sensation
  • Contains high levels of caffeine; monitor your intake

Nutrient quality

90 Highest impact

The formula utilizes high-quality forms like methylcobalamin and pyridoxal 5-phosphate for optimal B-vitamin activity. Dosage levels for energy-related compounds are designed for focused performance rather than foundational health.

Ingredient transparency

78 High impact

While core B-vitamins are clearly listed, a significant proprietary matrix obscures the specific amounts of several metabolic compounds. This lack of detail reduces the ability to evaluate the exact nutritional contribution of the performance blend.

Customer satisfaction

92 Highest impact

Strong ratings from over one hundred reviews indicate a high level of consumer reliability and trust. Feedback consistently highlights satisfying results for energy and focus during performance-related goals.

Value for money

66 High impact

The cost per serving is high, reflecting the specialized performance formulation and premium branded ingredients. Value is moderate as many core ingredients are hidden within an undisclosed metabolic matrix.
