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.

Sinusitis gone
I always ensure I have vitamin C on hand. Since I started taking it, my sinusitis has disappeared completely, and I haven’t had a throat infection since.

Cold prevention
Knowing about Fujikawa Theory, I've been taking this for approximately three years. Although it may synergise with protein and other factors, my previous cycle of colds leading to sinusitis or bronchitis, which occurred five times a year, has vanished.

Effective vitamin C
This is my first experience with ascorbic acid from iHerb. When the coronavirus began to spread, I promptly decided to purchase vitamin C, D, and zinc. Initially, there was a shortage, but this ascorbic acid was among the first available, and I quickly bought it. Although it's simply ascorbic acid, not Ester-C or liposomal form, it truly WORKS! My husband and I take it once daily after breakfast, alongside 2000 IU of vitamin D. We experienced no side effects and actually feel more energetic. Previously, I would face sinusitis in the autumn, but I had no issues this time. I believe the vitamin C, along with D, made the difference.

Sinusitis relief
My affection for vitamin C is immense. With weak immunity and constant nasal issues leading to sinusitis, these struggles with green mucus are now behind me. Whenever I felt a sneeze coming on, a dose of vitamin C would help prevent illness, and even if I did get sick, it was more tolerable.
