We explored the effects of L-ascorbate, commonly known as Vitamin C, on chloride transport in sinonasal epithelial tissues. This research is particularly significant as it addresses the common condition of chronic rhinosinusitis (CRS) and its potential link to the function of the cystic fibrosis transmembrane conductance regulator (CFTR) — a key chloride ion channel.
During our investigation, we utilized freshly excised sinonasal tissues from both normal individuals and patients suffering from CRS. The tissues were carefully prepared and tested to understand how L-ascorbate influenced chloride secretion. Our findings revealed that the application of L-ascorbate notably enhanced chloride secretion in these tissues.
This is important because optimal chloride transport is essential for maintaining healthy mucosal surfaces and effective mucociliary clearance. Therefore, since decreased chloride secretion could lead to the worsening of sinus conditions, L-ascorbate presents a promising avenue for therapeutic intervention in improving mucociliary clearance for those affected by chronic sinus issues.

We evaluated the impact of antioxidants, specifically vitamin C, on acute maxillary sinusitis treatment through a study involving different treatment approaches. Patients received a mix of dibunol and vitamin C, delivered into the sinuses, while others only had traditional treatments like ampicillin and hydrocortisone.
This study involved control groups that helped us compare the effectiveness of the antioxidant treatment. Stunningly, we found that those receiving the antioxidant mixture demonstrated substantial improvements, with shorter treatment times and fewer overall interventions compared to the control group.
Additionally, positive changes in certain blood markers indicated that the antioxidant approach markedly enhanced the body's response to infection. These findings underscore the potential benefits of including vitamin C as part of a sinusitis treatment plan, especially when dealing with acute flare-ups.

Effective treatment
Large doses of vitamin C have worked wonders for me. I took 25,000mg daily and overcame my sinusitis in no time. I highly recommend this tablet; it's easy to take and can't cause an overdose.

Strong immunity boost
It’s fantastic! My family and I regularly drink Vitamin C Ester-C. I believe it helped us resist Covid. I first ordered vitamins from the iHERB website back in July 2020. I tend to catch colds often in the autumn, winter, and spring due to chronic sinusitis. However, I had sinusitis and not Covid, which I attribute to Ester-C and other vitamins from iHERB. Now I am a loyal customer, consistently ordering and consuming vitamins. Wishing good health to everyone!
