Nutrient quality

81 Highest impact

N-Acetyl-L-Cysteine serves as a bioavailable precursor to glutathione, while several botanical ingredients are present as simple powders rather than concentrated extracts. The diverse blend supports respiratory pathways, though the inclusion of low-dose vegetable powders may provide minimal functional impact.

Ingredient transparency

88 Highest impact

Specific amounts are disclosed for the majority of active ingredients, allowing for a clear assessment of the formula. A small proprietary blend at the end slightly reduces total transparency regarding botanical ratios.

Customer satisfaction

89 Highest impact

Consistently high ratings from a significant number of users suggest reliable performance for the intended purpose. Negative feedback is minimal and does not point to systemic quality or efficacy issues.

Value for money

84 Highest impact

Competitive pricing per serving makes this an accessible option for multi-ingredient herbal support. The complexity of the formula justifies the cost, despite the use of some non-extracted powders.

Report overview
PABA · 50 mg OverallScore82
A Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value
This respiratory support formula contains 50mg of PABA as a secondary ingredient. It maintains decent transparency and cleanliness, though it is not a cost-effective way to obtain PABA.
Fenugreek · 100 mg OverallScore45
F Active Ingredient Quality & BioavailabilityD+ Dose, Safety & Label TransparencyB+ Value
This respiratory support supplement includes fenugreek as a secondary component at a relatively low concentration. For targeted fenugreek benefits, a product with a more concentrated extract and higher dosage would likely be more effective.
