Analysis

This supplement features ashwagandha, maca, and epimedium to support a healthy response to physical and mental stress. It also provides L-arginine and L-tyrosine to assist with blood flow and neurotransmitter health.

The liquid softgel format and the addition of BioPerine are designed to help the body utilize these diverse ingredients. It fits best for someone looking for a high-value, multi-herb vitality supplement for long-term use.

Pros

  • Better value in the 150-count size
  • Wide variety of traditional vitality herbs
  • Liquid softgel format for better uptake
  • Includes BioPerine for bioavailability

Cons

  • Contains yohimbe, which can cause nervousness
  • Requires taking multiple softgels per day

Warnings

  • Monitor how you feel when taking it; yohimbe can be stimulating

Nutrient quality

78 High impact

The combination of botanicals and amino acids addresses multiple pathways for systemic vitality. However, the 60 mg dose of L-Tyrosine is extremely low and unlikely to provide significant cognitive support independently.

Ingredient transparency

92 Highest impact

Labeling discloses the amounts for most active components, allowing for a reasonable assessment of formula strength. Transparency is good regarding the total components of the multi-nutrient softgel.

Customer satisfaction

87 Highest impact

Ratings are generally positive, suggesting the product meets expectations for its intended use. Feedback indicates that the formula is well-regarded for its role in maintaining overall physical drive.

Value for money

71 High impact

The cost per serving is high compared to simpler formulas, reflecting the diverse range of ingredients. Value is primarily found in the multi-component synergy rather than the dose of any single nutrient.

Report overview
C+ Active Ingredient Quality & BioavailabilityD+ Dose, Safety & Label TransparencyF Value
Arginine supports the body's natural production of nitric oxide, which is essential for blood flow. This formula provides a small amount of arginine within a broader vitality-focused blend.
Ashwagandha · 120 mg OverallScore49
F Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyD- Value
This specialized formula includes ashwagandha root powder alongside several performance botanicals and an absorption complex. It is designed for total-body vitality but uses the least potent form of ashwagandha at a maintenance dosage.
Tyrosine · 60 mg OverallScore48
A- Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value
This formula contains a negligible amount of L-Tyrosine that is insufficient for providing any noticeable cognitive or metabolic support. It is better categorized as a multi-ingredient vitality supplement rather than a functional tyrosine product.
