Frequently Asked Questions
What is the best immune support supplement?
Based on our analysis of 655 immune support products, Lung, Bronchial & Sinus Health ranks #1 with a SupplementScore of 81/100. Scores are based on label quality - dosage transparency, formulation cleanliness, and ingredient disclosure.
How are immune support supplements scored?
Every product is scored algorithmically using data from the NIH Dietary Supplement Label Database. The SupplementScore evaluates dosage transparency (35 pts), label completeness (25 pts), formulation cleanliness (25 pts), and ingredient profile (15 pts).
Does a higher score mean the supplement works better?
No. The score reflects label quality, how transparent and clean the product label is, not clinical efficacy, bioavailability, or safety. A higher score means better label practices, not guaranteed results.
