 Jarrow Formulas, Vegan Quercetin, 500 mg, 100 Veggie Capsules | | |
Quercetin alleviates asthma symptomsQuercetin inhibits ferroptosis through the SIRT1/Nrf2/HO-1 signaling pathway and alleviates asthma disease. We explored how quercetin, a natural compound found in fruits and vegetables, can impact asthma symptoms. Using an ovalbumin-induced mouse model of asthma, we aimed to uncover whether quercetin can help inhibit a process known as ferroptosis, potentially offering a new therapeutic approach for asthma sufferers.
Our findings showed that quercetin effectively reduced inflammation in the asthmatic mice. Specifically, it lowered levels of inflammatory factors such as IL-4, IL-5, and IL-13—substances typically elevated during an asthma attack. Notably, we also observed that quercetin increased the levels of superoxide dismutase, an important antioxidant, while decreasing malondialdehyde and ferric ions that are associated with oxidative stress.
Additionally, quercetin appeared to boost the expression of key proteins involved in defending against oxidative stress, specifically SIRT1, Nrf2, and HO-1. This suggests that quercetin not only helps combat inflammation but may also protect against cellular damage within the lungs. Overall, our study indicates that quercetin holds promise as a beneficial treatment for asthma by addressing both inflammatory and oxidative stress pathways.

TMEM16A targeting mitigates asthmaTargeting TMEM16A ion channels suppresses airway hyperreactivity, inflammation, and remodeling in an experimental Guinea pig asthma model. We explored how targeting TMEM16A, a calcium-activated chloride channel, can potentially improve asthma symptoms. In a thoughtfully designed study using guinea pigs with allergic asthma induced by ovalbumin, we treated the animals with a specific blocker, CaCCinh-A01, delivered through inhalation.
The results were promising. We observed a notable reduction in cough reflex sensitivity and airway resistance among the guinea pigs treated with CaCCinh-A01. This suggests that the treatment may help improve overall airway function in asthmatic conditions.
Interestingly, while we found that ciliary beating frequency decreased, the treatment also reduced airway mucus viscosity by lowering the production of a key protein, MUC5AC. Additionally, there was a reduction in inflammatory markers, indicating a decrease in airway inflammation. We also noted diminished signs of airway remodeling, hinting that the treatment could potentially address structural changes in the airways typically seen in asthma.
Although further research is needed to fully assess TMEM16A's viability as a therapeutic target for asthma, our findings indicate that it may play a significant role in alleviating various aspects of the disease, including airway hyperreactivity, inflammation, and remodeling.

Pleuran and Vitamin C improve asthmaBeneficial effects of pleuran on asthma control and respiratory tract-infection frequency in children with perennial asthma. We conducted a thorough investigation to examine how vitamin C, when combined with pleuran (a natural extract from mushrooms), influences asthma control and respiratory health in children with partially controlled perennial asthma. Our study was a double-blind, placebo-controlled clinical trial involving 230 children aged 7 to 17 years, split evenly into an active treatment group and a placebo group.
Over a 24-week period, children in the active group received both pleuran and vitamin C, while the placebo group received vitamin C alone. It was exciting to find that children younger than 12 years who received the combination treatment showed notable improvement in their control of asthma symptoms compared to those on placebo. Additionally, older children in the active group reported fewer respiratory infections, an important benefit for their overall health.
By the end of our 48-week study, we saw a significant improvement in asthma control in a high percentage of children receiving the active treatment. Notably, this combination appeared safe, with no serious side effects reported. Overall, our findings suggest that while vitamin C's isolated effects can't be fully assessed due to its combination with pleuran, the combined treatment offers promising benefits for managing asthma in children.

 Doctor's Best, High Absorption Magnesium, 200 mg, 120 Tablets, (100 mg per Tablet) | | |
Magnesium sulfate aids pediatric asthmaPharmacokinetics and Pharmacodynamics of Intravenous Magnesium Sulfate in Pediatric Acute Asthma Exacerbations. We explored how intravenous magnesium sulfate (IVMg) can help children facing severe asthma attacks. The study included 49 pediatric patients who were treated with IVMg after presenting to the emergency department. Some received a placebo, while others were given either 50 or 75 mg/kg of magnesium.
Our analysis showed that higher magnesium levels in the blood were linked to improvements in asthma symptoms, specifically reductions in the Pediatric Respiratory Assessment Measure scores. This suggests that IVMg could be an effective treatment for moderate to severe asthma exacerbations in children.
Interestingly, we noticed that only two out of 31 participants experienced hypotension, showcasing the safety of IVMg, as severe side effects are rare. Moreover, we proposed that a total serum magnesium area under the concentration-time curve greater than 63.1 mg h/L might be a useful target for effective dosing. Further research in larger studies is necessary to confirm these findings, but they indicate that IVMg could serve as a beneficial adjunct treatment for young patients suffering from asthma attacks.

Eicosapentaenoic acid improves asthmaEffects of low-dust forages on dust exposure, airway cytology, and plasma omega-3 concentrations in Thoroughbred racehorses: A randomized clinical trial. We compared how different types of forage affected asthma in Thoroughbred racehorses. Our focus was on assessing dust exposure, airway health, and the presence of eicosapentaenoic acid (EPA), an omega-3 fatty acid known for its anti-inflammatory properties. The horses were randomly assigned to three diets: dry hay, steamed hay, or haylage for a period of six weeks.
Throughout the study, we observed that horses fed steamed hay and haylage had significantly lower dust exposure compared to those that consumed dry hay. Interestingly, those on the haylage diet not only showed reduced levels of neutrophils in their bronchoalveolar lavage fluid, indicating better airway health, but they also had an increase in the ratio of anti-inflammatory to pro-inflammatory lipids, particularly EPA.
In fact, the horses on haylage had higher ratios of eicosapentaenoic acid compared to both their baseline measurements and horses on the other diets. This suggests that incorporating haylage could be beneficial for managing asthma symptoms in racehorses. Overall, it appears that haylage may help improve respiratory health by reducing inflammation linked to asthma through its higher anti-inflammatory lipid profile. Effective asthma treatment Most Useful Review It helps with asthma very effectively, especially when taken with zinc and magnesium. |

Dietary zinc may reduce asthmaAssociation between dietary zinc intake and asthma in overweight or obese children and adolescents: A cross-sectional analysis of NHANES. We explored the relationship between dietary zinc intake and asthma in overweight or obese children and adolescents. This research utilized data from the National Health and Nutrition Examination Survey, focusing on those aged 20 and younger who had both asthma and dietary zinc consumption.
Our findings indicate that there is an inverse association between zinc intake and the occurrence of asthma. In simpler terms, higher dietary zinc appears to be linked with lower asthma rates in these children. This suggests that zinc could play an important role in respiratory health, especially for kids struggling with their weight.
While our study sheds light on this potential protective effect of zinc, we recognize that the results in existing literature have been mixed. Some research indicates benefits, while other studies don’t show significant effects. Therefore, while we have uncovered a correlation worth noting, further research is required to fully understand zinc’s role in asthma management.

 Doctor's Best, MSM with OptiMSM®, 3,000 mg, 360 Capsules (1,000 mg per Capsule) | | |
Asthma medication boosts lung functionAn application of model-fitting procedures for marginal structural models. We explored the effectiveness of asthma rescue medication on lung function through a thorough analysis of data collected during the Fresno Asthmatic Children's Environment Study from 2000 to 2002. Our research utilized a method known as inverse probability of treatment weighting (IPTW) to evaluate treatment effects in an observational study context. This approach helps us account for various confounding factors that might influence the outcomes we observe.
In our findings, traditional regression methods suggested that there was no significant association between medication use and improved lung function. This might seem surprising, as one would intuitively expect that asthma medication helps improve breathing. However, we believed that this outcome was likely influenced by confounders, such as asthma symptoms and severity, which can muddle the clear effects of medication.
When we applied our marginal structural model approach, we discovered a causal link between medication use and a 7% improvement in pulmonary function. This suggests that when we accounted for other influences adequately, asthma rescue medication does indeed have a positive impact, contrary to previous findings.
We hope that our discussion on the importance of proper model selection and fitting procedures encourages more researchers to consider these aspects seriously when evaluating treatment effects. By understanding the subtleties of our methodologies, we can better justify our conclusions in the realm of asthma treatment.

 Doctor's Best, High Absorption CoQ10 with BioPerine®, 100 mg, 120 Veggie Caps | | |
CoQ10 levels low in asthmaLevels of coenzyme Q10 in asthmatics. We investigated how coenzyme Q10 (CoQ10), an antioxidant, influences individuals with asthma. In our study, we enrolled 56 patients with asthma and compared them to a control group of 25 healthy volunteers. This approach allowed us to assess the differences in antioxidant levels, particularly focusing on CoQ10, alpha-tocopherol, beta-carotene, and malondialdehyde (a marker of oxidative stress).
Our findings revealed that both CoQ10 and alpha-tocopherol levels were significantly lower in asthma patients compared to healthy individuals. Interestingly, while the level of malondialdehyde was higher in asthmatics, it did not reach statistical significance. We also found that the concentration of CoQ10 had a positive correlation with alpha-tocopherol levels, suggesting that they may work together in the body's defense against oxidative stress.
Ultimately, these results suggest that having lower levels of CoQ10 might contribute to an imbalance in antioxidants among asthma patients. Though the study highlights a potential link, it is crucial to note that we did not demonstrate a direct therapeutic benefit as we did not isolate CoQ10's effects from other treatments. Future research could further explore the role of CoQ10 supplementation in managing asthma symptoms.
