Iodine reduces rhinovirus infections
We explored the effectiveness of 2% aqueous iodine in preventing infections caused by rhinoviruses, the culprits behind the common cold. In a controlled setting, volunteers had their fingers treated with iodine before being exposed to the virus. Remarkably, none of the eight participants who received the iodine treatment became infected immediately afterwards. In contrast, all of the seven volunteers treated with a placebo did get infected.
We also noticed that when exposure occurred two hours after iodine application, only one out of ten volunteers fell victim to the virus, whereas six out of ten in the placebo group became ill. The difference was notable, though not quite statistically significant. Additionally, tests showed virus presence in only 11% of hand washes from those who used iodine, compared to 41% from the placebo group, suggesting that iodine may substantially reduce virus contamination on hands.
Overall, these findings indicate that using iodine could be an effective strategy in preventing common cold infections, especially right after treatment. It seems that applying iodine to our hands may serve as a protective measure against rhinovirus, significantly reducing the chances of getting sick.

PVP-I gargle effectively reduces infections
We explored the effects of povidone-iodine (PVP-I) gargle on the prevention of common colds and influenza by comparing its bactericidal activity with that of other commercially available gargles. In our study, we tested PVP-I against chlorhexidine gluconate and cetylpyridinium chloride using different strains of bacteria. This involved both lab tests measuring bactericidal effects and practical assessments of how effective these gargles were in reducing oral bacteria counts after use.
Interestingly, our findings revealed that PVP-I not only demonstrated the highest bactericidal rate but also significantly reduced the number of bacteria in the mouth after gargling. Additionally, we conducted a survey to gauge users' feelings about each gargle, which added a personal touch to our investigation.
We also looked at real-world impacts by encouraging middle school students to use the PVP-I gargle, which seemed to reduce their absence rates due to colds and flu. This suggests that regular use of this particular gargle may aid in preventing common respiratory infections, making it a beneficial practice for both individuals and communities.

Iodine's mixed effects on colds
We investigated the role of iodine in preventing the common cold, specifically regarding its effectiveness against rhinovirus infections. Many of us have experienced the discomfort and disruption that comes from a cold, and we know how hard it can be to find effective remedies. Initial studies suggested that treating our hands with iodine could help prevent the spread of these pesky viruses.
Iodine has shown potential in reducing rhinovirus transmission. It's known that viral contamination on our hands plays a significant role in how colds spread from person to person. In fact, the use of iodine for hand treatment could disrupt this transmission chain effectively.
Although iodine's effects are promising, the specific details and methodologies of the studies were not deeply explored. Importantly, other organic acids like salicylic and pyroglutamic acid also demonstrated strong virucidal action against rhinoviruses. These findings hint at the potential for various treatments to help us fend off colds.
Overall, while iodine treatment shows some promise, the evidence isn't entirely conclusive, as further detailed studies would be beneficial for confirmation. It remains an engaging area for future research in our efforts to combat the common cold.

This is not my first purchase of this iodine. Combined with selenium, it has shown remarkable effects! Having AIT and hypothyroidism for years, I take these supplements a few times a year and feel improvements almost immediately. I have more energy, am warmer, my skin feels better, and my hair falls out less. However, the dosage is quite high, so for prevention, a smaller dose is advisable for less experienced individuals.

I've been ordering this excellent iodine for the past 3-4 years, taking one capsule daily with breakfast. My well-being has significantly improved since starting iodine, leading to increased energy and activity. This is essential for my wife and me, as it’s harder to be cheerful and active at our age. Our region suffers from iodine deficiency, making this high-quality iodine essential.

Dealing with hypothyroidism and low blood pressure, I tried Life Extension's Sea-Iodine. Their supplements are of high quality, so I felt confident. I take this once a week, and it has significantly improved my symptoms. I no longer feel cold after just a few days, and it has increased my energy and focus. It has transformed my management of my hypothyroidism and low blood pressure; I highly recommend it.

Noticed difference

I don’t officially have hypothyroidism, but my thyroid levels are low. Despite doctors insisting I’m fine, I struggle with coldness, weight management, and hair loss. After a month of taking this, I noticed a significant difference, although I did see an increase in facial hair. I suspect it’s just how my body reacts due to my Italian background.

My husband and I take one capsule on an empty stomach. He used to feel cold even in the summer after a shower, but after taking iodine, he seems calmer. I believe iodine is the cause. I will also give half a capsule to my children. It’s budget-friendly, natural iodine.👍
