Red flags we can name
The whole formula sits inside one undisclosed proprietary blend, so no individual dose is verifiable, and 600 mg spread across eleven ingredients averages roughly 55 mg each — below the amounts used in most published trials. Four of the eleven (lutein, zeaxanthin, bacopa, ginkgo) have evidence bases in eye health and cognition rather than respiratory health. The "third party lab tested" line is the vendor's own artwork with no certificate of analysis attached, and the bottle carries structure/function claims that are asterisked rather than proven. We found no published clinical trial of this finished formula.
What actually checks out
The Supplement Facts panel is photographed on the live listing and matches the transcription on this page, including the three inactive ingredients. The seller is identifiable — Blue Horizon Brands of Salisbury, North Carolina — with a 30-day return window, seller-paid return postage and the marketplace guarantee behind it. Directions are specific rather than vague. Several individual ingredients, notably green tea catechins and the B vitamins, are real nutrients with genuine literature, even if the amounts here are unknown. Nothing on the packaging claims to treat a disease.
What form does PureLung come in — capsule, gummy or liquid drops?
PureLung is sold as capsules and only as capsules. The bottle holds 60 capsules, the serving is two capsules, and that gives 30 servings — roughly a month per bottle. There is no gummy, no powder, no tincture and no liquid drop version of PureLung on the listing we checked, so any page offering you "PureLung gummies" is describing something the manufacturer does not sell.
What does PureLung cost, and where do you buy it?
PureLung is sold through a marketplace listing rather than a dedicated brand checkout, which is unusual for a supplement marketed this way. On 9 August 2026 the listing showed US$29.95 for a two-bottle pack — the marketplace's own per-unit line reads that as US$14.98 a bottle — with Best Offer enabled and free shipping. That is a marketplace price, not a fixed one: it moves, and listings end. There is no published single-bottle price and no subscription. The only figure worth acting on is the one on the listing on the day you open it, which is where our buy link goes.
What do PureLung buyer reports actually tell you?
Very little that is reliable, and we would rather say so than pad this page. The feedback score attached to the listing (99.4% across 4,341 ratings) rates the seller's shipping and service across everything they sell, not this formula's effect on anyone's breathing. Marketplace comment volume for this specific product is thin, unverified and not collected under any protocol. We publish no star score for PureLung and we aggregate no buyer comments into a number, and a site that does is doing marketing rather than measurement.
What the evidence does not show
To be plain about the limits: there is no published human trial of the PureLung blend itself, no evidence that it restores or "rejuvenates" lung tissue, no evidence it improves measured lung function such as FEV1, and no evidence it treats, prevents or reduces asthma, COPD, bronchitis or any infection. Ingredient-level research is not product-level proof, and with the individual amounts undisclosed even the ingredient-level research cannot be applied to this bottle. Antioxidant supplementation in smokers deserves particular caution: the ATBC trial in The New England Journal of Medicine reported higher lung cancer incidence among male smokers given beta-carotene, and the CARET trial reported the same direction of harm on beta-carotene plus vitamin A. For general guidance on judging any supplement claim, the NIH Office of Dietary Supplements and NCCIH both publish plain-language checklists, and an analysis in JAMA found that supplements named in FDA warning letters frequently remained on sale afterwards.
