Gitelman syndrome impacts infant development
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.

We investigated the impact of potassium arsenite on chronic fatigue syndrome (CFS) in two veterinary professionals. After struggling with CFS despite various treatments, they turned to a low dosage of potassium arsenite for ten days. Remarkably, both experienced a complete remission of their symptoms, and follow-up tests showed a notable improvement, including the disappearance of the bacteria from their blood.
While this suggests a potential link between bacterial infections and CFS, it's important to note that broader implications for treatment require more extensive research. This case prompts intriguing questions about the role of infections and alternative therapies in managing CFS.

Daytime fatigue reduced

I recommend this product! Initially doubtful, after a month's use of iodine (with selenium), I now wake up easier in the mornings. Daytime fatigue and drowsiness have vanished, along with a noticeable energy boost and improved memory. Highly recommended!

Improved fatigue symptoms
An effective drug for general health and metabolic processes, addressing iodine deficiency effectively. The quality and composition are good, with a high dosage compared to similar products, which is a significant advantage. The supplement notably improves immunity and is essential for the body's metabolic processes, particularly the thyroid gland. I experienced a resolution of chronic fatigue symptoms. My family, aged 30 to 65, has been taking it for several months, with regular courses and breaks. The tablets are small, neutral in taste, and easy to swallow; the packaging is convenient and airtight.

No noticeable effect
3 people found this helpful
I’ve been purchasing from iHerb for over a decade, spending thousands on supplements for fatigue. I can confirm this supplement is of good quality. However, I didn’t notice any improvement in my health after taking it for weeks. One supplement that consistently works for me is Thorne’s Advanced Nutrients multivitamin; I feel energised shortly after taking it.
