What the research says about Healthy Lungs' ingredients
Educational summaries of published research on the individual ingredients in CanPrev Healthy Lungs; not product-specific claims. This product's own authorized claim is under NPN 80030695.
NAC's mucolytic, antioxidant and anti-inflammatory activity reviewed across COPD traits
A 2024 review of the 'treatable traits' strategy in COPD highlights N-acetylcysteine as a widely used mucolytic agent whose antioxidant and anti-inflammatory activity may benefit frequent productive cough, chronic bronchitis, airway inflammation and exacerbations.
ReviewMeta-analyses found NAC reduced exacerbations in chronic bronchitis and pre-COPD
Two meta-analyses covering 20 studies found NAC significantly reduced the incidence of exacerbations in both COPD and chronic bronchitis/pre-COPD patients, and CB/pre-COPD patients treated with NAC were significantly more likely to see improved symptoms or quality of life versus placebo.
Meta-analysisA pooled analysis of 11 trials found NAC reduced exacerbations and improved symptoms
A meta-analysis of 11 publications (775 NAC patients, 789 controls) found NAC significantly reduced the frequency of chronic bronchitis exacerbations and significantly improved symptoms compared with placebo, without increasing adverse effects, at a regular low dose for at least 3 months.
Meta-analysisNAC supplementation improved brain antioxidant-linked connectivity
A pilot randomized trial found 6-month N-acetyl-cysteine supplementation increased functional connectivity within the cingulate cortex in early psychosis patients, consistent with NAC's role as a glutathione precursor supporting antioxidant defense.
Human RCTDecreased a marker of oxidative stress in a clinical trial
An 8-week randomized trial of NAC (600 mg twice daily) in multiple sclerosis patients found it significantly decreased serum malondialdehyde, a marker of lipid peroxidation, versus placebo, alongside improved anxiety symptom scores.
Human RCTIncreased an antioxidant enzyme's activity in a placebo-controlled trial
A randomized, double-blind, placebo-controlled trial of NAC (600 mg twice daily for 3 months) in rheumatoid arthritis patients found it significantly increased glutathione peroxidase activity from baseline, alongside reductions in nitric oxide and fasting blood sugar.
Human RCTDecreased inflammatory cytokines in a 90-day randomized trial
A double-blind, placebo-controlled trial of 500 mg/day quercetin for 90 days in postmenopausal women found it significantly decreased interleukin-6 and TNF-alpha levels compared with placebo.
Human RCTImproved recovery from exercise-induced muscle damage
A randomized crossover trial found 14 days of quercetin supplementation (1000 mg/day) attenuated strength loss and improved neuromuscular recovery after eccentric exercise-induced muscle damage, attributed to its antioxidant and anti-inflammatory action.
Human RCTA safety trial found no significant change in inflammatory markers at a modest dose
A 6-week randomized crossover trial of 162 mg/day quercetin in overweight subjects with prehypertension found it was safe but did not significantly change CRP, TNF-alpha, leptin or adiponectin compared with placebo - a reminder that quercetin's effects can be dose- and context-dependent.
Human RCTConfirmed recycling activity in living human cells
In intact human leukemia cells, dihydrolipoic acid was shown to recycle oxidized phenoxyl radicals of a vitamin E homologue back to their parent antioxidant form, working together with ascorbate.
MechanismCalled the 'universal antioxidant' for its dual solubility
A review describes lipoic acid as able to act in both aqueous and lipid environments, increasing the expression of antioxidant enzymes and participating in the recycling of vitamins C and E.
ReviewAn antioxidant researched for eye-surface comfort
A narrative review describes alpha-lipoic acid as a potent antioxidant studied for dry eye and ocular surface disease, noting its interaction with vitamin C and glutathione and its potential to recycle vitamin E.
Review70 years of research into a standardized grape seed flavonoid extract
A review tracing grape seed extract research from its creation in 1947 describes an 8-week human supplementation study that found favorable changes in vascular gene expression and inflammatory pathways in healthy volunteers.
ReviewReduced oxidative stress markers during cardiac bypass surgery
A randomized trial in 87 patients undergoing coronary bypass surgery found grape seed extract (100 mg every 6 hours pre-operatively) and vitamin C both increased total antioxidant capacity and reduced malondialdehyde compared with untreated controls.
Human RCTImproved inflammation and glycemic markers in type 2 diabetes
A double-blind randomized crossover trial of grape seed extract (600 mg/day for 4 weeks) in type 2 diabetes patients at high cardiovascular risk found significant improvements in whole blood glutathione, C-reactive protein and fructosamine compared with placebo.
Human RCTRegular vitamin C reduced cold severity and halved incidence under physical stress
A 2025 review found that in 15 trials (6,244 participants), regular supplementation of 1 gram or more of vitamin C per day decreased the severity of colds by 15%, and in 5 trials of people under heavy physical exertion, it halved the incidence of colds.
ReviewShortened cold duration and prevented pneumonia in specific populations
A review of 148 animal and numerous human studies found regularly administered vitamin C shortened the duration of common colds, and 3 controlled trials found vitamin C prevented pneumonia in specific at-risk groups such as military recruits and hospitalized patients.
ReviewA Cochrane meta-analysis of 29 trials found a consistent reduction in cold duration
A Cochrane meta-analysis of 29 trial comparisons (11,077 participants) found regular vitamin C prophylaxis reduced common cold duration by 8% in adults and 13.5% in children, with a pooled relative risk of 0.50 for cold incidence in physically stressed subgroups like marathon runners and soldiers.
Systematic Review / Meta-analysisZinc status shown to influence antiviral immune defense
A review of zinc's role in antiviral immunity describes zinc as crucial for immune function, noting zinc-deficient populations are often most at risk of viral infections, and summarizing evidence for zinc's therapeutic use against viruses including the common cold.
ReviewZinc supplementation may shorten cold duration by about a third
A review of 82 eligible studies on nutrients and the common cold found zinc supplementation may shorten cold duration by approximately 33%, with the greatest benefit when taken within 24 hours of symptom onset.
ReviewVitamin C plus zinc combination reduced cold symptom duration
A pooled analysis of two double-blind, randomized, placebo-controlled trials (94 participants) found a combination of 1000 mg vitamin C plus 10 mg zinc was significantly more effective than placebo at reducing rhinorrhea duration over 5 days of treatment, with quicker symptom relief and good tolerability.
Human RCTIncreased antiviral defenses in bronchial epithelial cells
An in vitro study found vitamin D decreased rhinovirus replication and release in human bronchial epithelial cells, while increasing interferon-stimulated genes and cathelicidin, an antimicrobial host-defense peptide with direct antiviral activity.
Laboratory studyVitamin D induces a key airway antimicrobial peptide
A study of airway epithelial host defense found vitamin D is an important regulator of respiratory host defense, increasing expression of the antimicrobial peptide hCAP18/LL-37 under normal conditions.
Laboratory studyAdequate vitamin D status linked to lower breakthrough infection risk
An observational study of 114 vaccinated adults found that chronic cholecalciferol supplementation and higher circulating vitamin D concentrations were independently associated with a reduced risk of SARS-CoV-2 breakthrough infection after mRNA vaccination.
