Analysis

This formula combines aged garlic and nattokinase to help with heart health and blood flow. It includes Suntheanine, which is a very clean form of the amino acid L-theanine often used for relaxation.

The amount of theanine provided is 24mg per serving, which is much lower than standard relaxation doses. It fits best as a daily maintenance tool for circulatory health rather than for immediate stress relief.

Pros

  • Uses branded Suntheanine for purity
  • Includes odorless aged garlic extract
  • Supportive of heart health goals
  • Convenient capsule format

Cons

  • Very low theanine dosage
  • Garlic can cause mild breath issues
  • Contains multiple complex ingredients

Warnings

  • Check with a professional if taking blood thinners
  • May lower blood pressure significantly
  • Stop use two weeks before surgery

Nutrient quality

84 Highest impact

Selection of standardized garlic and branded theanine ensures high ingredient integrity and reliability. However, the low concentration of theanine relative to clinical standards limits the potency for specific cognitive goals.

Ingredient transparency

98 Highest impact

Milligram amounts for all active ingredients are clearly stated on the supplement facts panel. Specific branding for the ingredients adds another layer of trust regarding the source materials.

Customer satisfaction

92 Highest impact

Consistently high ratings across a large volume of reviews indicate reliable performance for most users. Minimal negative feedback regarding side effects suggests the blend is well-tolerated by the general population.

Value for money

81 Highest impact

Premium ingredient forms justify a higher price point compared to generic garlic supplements. The cost per serving is reasonable given the specialized nature of the enzyme and amino acid components.
