Zinc Levels and Sinusitis Effects
We explored the connection between zinc levels and chronic rhinosinusitis, particularly focusing on patients with nasal polyps. The study involved 105 participants divided into three groups: those with eosinophilic polyps, those with neutrophilic polyps, and a control group of individuals who underwent surgery for reasons other than polyposis.

We measured the serum zinc concentrations in these groups to see if there were any significant differences. Our findings revealed that patients suffering from chronic rhinosinusitis and having neutrophilic polyps had notably lower zinc levels compared to the general population. However, the zinc levels in patients with eosinophilic polyps did not show a significant difference when compared to healthy controls.

While we saw a clear distinction in zinc levels between the neutrophilic group and the control group, the overall data suggests that zinc's role in sinusitis, especially for those with eosinophilic polyps, may not be as pronounced. As such, while zinc might contribute to inflammation in specific cases, its effectiveness as a standalone treatment for sinusitis remains uncertain.

Reduced cold symptoms

Initially, I was doubtful about using aids for colds, as I had experienced ARVI without issues. However, after breaking my nose, I nearly developed Sinusitis. Now, I meticulously wash my nose. Following recommendations about zinc and vitamin C, I began taking them alongside ARVI picked up from my children. I took zinc and vitamin C twice daily at 500 mg each. Astonishingly, instead of the usual three days of discomfort and an additional 4-5 days recovery, I only endured one difficult day and had a quicker recovery. Even my nasal issues improved! A word of caution: if taken on an empty stomach, nausea may occur, but eating shortly after resolves it.

Improved immunity response

This has become a staple in my morning immunity booster routine. I take it first thing, alongside my California Gold Colustrum supplement, on an empty stomach. I've been using it for three weeks, and I feel quite well. My Sinusitis has not been as severe, even in this cold weather. I will certainly repurchase this once I've finished the bottle.
