Product analysis

51 out of 100

Astragalus 450 mg has an uncertain role in everyday immune support, and its unspecified preparation makes quality difficult to compare.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality20

The astragalus preparation is not specified, so quality cannot be judged confidently. The amount alone does not establish equivalence to a defined extract.

Ingredient Transparency63

The astragalus amount is stated, making serving quantity clear. The preparation is not identified, which limits comparisons between powders and extracts.

Value For Money40

Value for money cannot be judged reliably. A usable price comparison for the astragalus contribution is unavailable.

Customer Satisfaction74

Customer ratings are very positive, though the number of ratings is modest. The feedback is encouraging but gives a limited picture of wider satisfaction.

Product Focus90

A single herb keeps the formula centered on immune support. Immune-cell findings do not establish a reliable everyday benefit or equivalence between different preparations.

A+ Ingredient FitC- PathwaysA+ EvidenceA+ Formulation Logic

Astragalus receives a contribution in the saved calculation, focused on innate immune activity. Traditional use and immune-cell findings do not establish a reliable routine adult respiratory benefit, however. The declared 1350 mg serving meets the saved amount comparison, but the supplied context does not establish a clinically effective prevention dose or powder-to-extract equivalence.

How this product is rated for Immunity

Ingredient fit100

Astragalus contributes to the supplied ingredient findings. Its relevant amount comparison is met.
Goal fit
The formula is focused on the contributing ingredients, though they may also serve other purposes.
Dose adequacy
The contributing amounts meet the supplied comparisons, without establishing an optimal clinical regimen.

Pathways57

The strongest supplied connection is to innate immune cell activity. This describes the ingredients' assigned roles rather than an observed clinical outcome.
Depth
The strongest assigned connection is to innate immune cell activity, rather than a demonstrated change in infection outcomes.
Breadth
The supplied findings meaningfully cover one immune area.

Evidence95

Astragalus leads the saved evidence finding, but the supplied population, preparation or endpoint limits prevent a general adult infection-prevention claim.
Evidence strength
Astragalus leads this finding, although its supplied context does not establish routine immune protection for general adults.
Studied preparation
The preparation passes the saved check, but that does not resolve the supplied differences from clinically studied regimens.

Formulation logic100

The contributing ingredients have no missing required partner, and no listed formulation conflict was triggered.
Partner coverage
The contributing ingredients can act independently, so no missing required partner reduces their contribution.
Conflicts
No listed formulation conflict was triggered by the supplied facts.
Effective doses
All contributing ingredients meet the supplied minimum amount comparison; this is not proof of a clinically effective regimen.
