Common Cold details

Iodine reduces rhinovirus infections

Based on 3 Researches

Gwaltney JM, Moskalski PB, Hendley JO. Interruption of experimental rhinovirus transmission. J Infect Dis. 1980;142:811.

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.

Should have bought this ages ago! I experienced an immediate enhancement in my hypothyroidism symptoms. My cold hands and feet became warm, and my energy and mood lifted substantially. I paused the iodine/potassium supplement for a few days to verify the improvements, and they were indeed linked. I regret not starting this sooner! I adore NOW brand supplements and have always been satisfied with their quality and price.

Depression details

I recently began waking up feeling breathless and experiencing nightmares, which was unusual for me. I felt a horrible weakness and tiredness upon waking. After realising I might lack iodine, I started this supplement. Now, I no longer have nightmares or breathlessness, and I’ve regained strength. My depression lifted, and I feel more alive than before. This product has been invaluable!

High Cholesterol details

Faba bean water's cholesterol-lowering potential

Based on 5 Researches

Feng Z, Morton JD, Maes E, Kumar L, Serventi L. Proximate composition, peptide characterization and bioactive properties of faba bean blanching water. Food Res Int. 2025;200:115426. doi:10.1016/j.foodres.2024.115426

We investigated the qualities of faba bean blanching water, especially its potential effects on cholesterol levels. This study showed that the processing water, packed with protein and minerals, especially potassium, might have cholesterol-lowering abilities due to its inhibitory effects on HMG-CoA reductase—a key enzyme in cholesterol production. The results were promising, indicating around 67% inhibition of this enzyme, which could benefit those looking to manage cholesterol without extensive dietary changes. Overall, faba bean blanching water can be a sustainable option with health perks.

Potassium treatment aids neuron recovery

Based on 5 Researches

Fazio L, Naik VN, Therpurakal RN, Gomez Osorio FM, Rychlik N, et al. Retigabine, a potassium channel opener, restores thalamocortical neuron functionality in a murine model of autoimmune encephalomyelitis. Brain Behav Immun. 2024;122:202. doi:10.1016/j.bbi.2024.08.023

We explored how a specific potassium channel opener, Retigabine, impacts thalamic neuron functionality in autoimmune encephalomyelitis, a model for Multiple Sclerosis. In the study, we created localized inflammatory lesions in the brains of mice to mimic the disease effects.

By testing Retigabine, we observed its potential to improve neuron excitability and information processing in these affected areas. The results indicate that this treatment might effectively reduce the adverse effects of inflammation on the brain, supporting its role as a neuroprotective agent.

M-channel activation mitigates arrhythmias

Possibly Effective

Based on 7 Researches

Peng JQ, Zhou MM, Xu L, Wang X, Tang YH, et al. Targeted M-Channel Activation in the Left Stellate Ganglion Protects Against Ischemia-Induced Ventricular Arrhythmias in Canines. J Am Heart Assoc. 2025;14:e039059. doi:10.1161/JAHA.124.039059

We examined whether activating M-type potassium channels in the left stellate ganglion could help manage heart issues during acute myocardial ischemia (AMI). In our study involving beagles, some received an M-channel activator called retigabine before inducing AMI.

The results were promising—we noticed that retigabine reduced excessive sympathetic activity, leading to fewer arrhythmias. Moreover, it allowed for better heart rhythm stability and increased resistance to ventricular fibrillation compared to those who did not receive treatment. These insights suggest that targeting M-channels could be a valuable approach in reducing heart rhythm disturbances during ischemic events.

Hypothyroidism details

Iodine supplementation restores thyroid function

Based on 16 Researches

Seetharaman S, Sasidharan Pillai S, Ganta A, Millington K, Quintos JB, et al. Iodine Deficiency Hypothyroidism Among Children in the United States - 21st Century Resurgence?. AACE Clin Case Rep. 2024;10:236. doi:10.1016/j.aace.2024.08.003

We looked into the growing concern of iodine deficiency hypothyroidism among children in the United States. This condition, which can lead to cognitive and physical impairments, was thought to be largely eliminated thanks to universal salt iodization started in the 1920s. However, recent trends suggest that iodine deficiency could be reappearing due to increased use of noniodized salts, lower iodine levels in dairy, and dietary restrictions like veganism or food allergies.

Over an 18-month period, we documented a series of cases where three children were diagnosed with iodine deficiency hypothyroidism despite having no underlying thyroid dysfunction. Their clinical presentations varied significantly—some had large goiters while others showed mild or no goiter at all. The results of their biochemical tests also highlighted a range of thyroid-stimulating hormone elevations.

Importantly, all patients returned to normal thyroid function following iodine supplementation. We propose that measuring spot urine iodine levels alongside elevated serum thyroglobulin could serve as a simpler and effective diagnostic approach, moving away from the more complex 24-hour urinary iodine tests. Our findings shine a light on the necessity of addressing iodine deficiency in today’s dietary landscape.

Reduced thirst feelings

Most Useful Review

I found this iodine supplement amazing as it contains calcium iodide rather than kelp, which can vary in iodine content. Since I have hypothyroidism, I often experienced dehydration despite drinking enough water, which left me feeling thirsty. This supplement supports my thyroid function and remarkably reduces my thirst. It's a very effective product, providing honest feedback without any embellishments. I appreciate it!

Cold details

Works well as a thermogenic and mild stimulant. Whenever I start feeling a bit cold and run down, a tablet of this supplement provides the warmth and boost I need. It also increases my metabolism, so be prepared for more toilet visits. To summarise, for enhancing body temperature and aiding sluggish metabolism and constipation, potassium iodide works wonders.

Everyone needs potassium. I ordered it for my mum ♥️ as it aids in treating allergies, detoxifies, and helps reduce blood pressure. The overall effect is complex and tremendously beneficial.

Gitelman syndrome impacts infant development

Likely Very Effective

Based on 2 Researches

Skalova S, Neuman D, Lnenicka P, Stekrova J. Gitelman syndrome as a cause of psychomotor retardation in a toddler. Arab J Nephrol Transplant. 2013;6:37.

We examined a unique case of an 18-month-old boy diagnosed with Gitelman syndrome, a rare condition leading to developmental delays.

His symptoms included psychomotor retardation and low potassium levels. Genetic tests confirmed mutations in the SLC12A3 gene, responsible for this condition.

After oral potassium supplementation, we observed remarkable improvement in his potassium levels and developmental progress. This case highlights the importance of recognizing Gitelman syndrome in young children with growth and developmental issues, as early treatment can lead to positive outcomes.

I was astounded by the effects! After taking this pill, I woke up for the first time in a year feeling wholly refreshed and free from pain. I’ve been breastfeeding and had joint pain since mid-pregnancy (pelvis, groin, knees, elbows). I realised this wasn’t just postpartum; it was a noticeable deficiency. Although calcium and magnesium improved my mood, they didn’t help with pain relief until I tried iodine. After one pill, I could feel no discomfort—what a miracle!

Headache details

Potassium may moderately affect migraines

Questionable

Based on 7 Researches

Xu L, Zhang C, Liu Y, Shang X, Huang D. Association between dietary potassium intake and severe headache or migraine in US adults: a population-based analysis. Front Nutr. 2023;10:1255468. doi:10.3389/fnut.2023.1255468

We explored the potential connection between dietary potassium intake and the occurrence of severe headaches or migraines. Utilizing data from over 10,000 US adults gathered through a national health survey from 1999 to 2004, we conducted a thorough analysis.

While we found that higher potassium intake was linked to a lower likelihood of migraines, the relationship appeared to be L-shaped, suggesting that there might be an optimal level of intake rather than a straightforward benefit. There's no strong evidence that potassium dramatically decreases headache frequency, but it does seem to play a role worth noting.

Possibly Effective

Based on 2 Researches

Shaikh N, Nashrah U, Suleiman RN, Amara UE, Ummunnisa F. The hyperemesis gravidarum and pulmonary embolism: A case report and review of literature. Qatar Med J. 2024;2024:39. doi:10.5339/qmj.2024.39

We explored the complications that can arise from hyperemesis gravidarum (HG), a severe condition affecting pregnant women characterized by persistent nausea and vomiting.

In one instance, a previously healthy 26-year-old woman with HG developed a bilateral pulmonary embolism despite receiving treatment.

Although nausea persisted during hospitalization, the combination of early detection and appropriate management allowed for a successful recovery.

This case highlights the need for careful monitoring and treatment to prevent severe outcomes in pregnant patients, especially when dehydration is involved.
