Analysis

The formula combines aged garlic and nattokinase with branded Suntheanine. Garlic and nattokinase are the main reasons to choose it, not the calming ingredient.

Suntheanine provides strong identity assurance, yet the amount is far below common focused servings. It is unlikely to anchor noticeable calm or attention support by itself.

The capsule may fit users who specifically want this three-part combination. As a theanine product, it is underdosed and relatively costly.

Who is it for
  • Adults specifically seeking garlic with nattokinase
  • Users treating theanine as a minor addition
  • People comfortable with a cardiovascular-oriented blend
Best for
  • Aged garlic and nattokinase supplementation
  • Multi-ingredient cardiovascular routines
  • Low-dose Suntheanine inclusion

Pros

  • Branded Suntheanine source
  • All active amounts disclosed
  • Substantial aged-garlic component
  • No proprietary blend

Cons

  • Theanine amount is very low
  • Poor theanine-specific value
  • Not designed for calm focus
  • Nattokinase activity units are not shown

Warnings

  • Nattokinase and aged garlic may increase bleeding risk with anticoagulant or antiplatelet medicines
  • The garlic-and-nattokinase combination may need to be stopped before surgery when advised
  • People with bleeding disorders should avoid unsupervised use

Nutrient quality

71 High impact

Suntheanine is a well-characterized branded L-theanine source. The small Suntheanine amount is unlikely to provide robust standalone theanine support.

.

Ingredient transparency

84 Highest impact

Every listed active has a specific amount, which makes the core formula straightforward to assess. The supplied data omits a complete excipient list and full intake directions.

.

Customer satisfaction

70 High impact

The supplied aggregate satisfaction signal is favorable. A large amount of feedback makes that aggregate signal reasonably stable, but no narrative evidence was provided.

.

Value for money

64 Moderate impact

Branded theanine and two additional actives partly justify the cost, but the theanine dose is weak. The serving offers only modest value for someone primarily seeking theanine.

Report overview
Theanine · 24 mg OverallScore70
A+ Active Ingredient Quality & BioavailabilityD+ Dose, Safety & Label TransparencyD+ Value

Suntheanine provides strong form and purity assurance, and its exact amount is disclosed. The dose is too small for a stand-alone theanine serving and offers weak theanine-specific value, although aged garlic and nattokinase also contribute to the formula. Nattokinase and aged garlic may add to bleeding risk for people using anticoagulant or antiplatelet medicines.
