Study: Effervescent tablets hide significant sodium content

Effervescent tablets, often consumed as a refreshing daily drink, are a common way people take dietary supplements. However, a study by the Institute of Nutrition has revealed a hidden danger: these tablets can be a significant source of sodium.

Dr. Maša Hribar from the institute highlighted that people often don't consider supplements as a source of salt, especially since effervescent tablets don't taste salty. "Our research shows that effervescent tablets can be a significant hidden source of sodium, especially with regular daily use," she warned.

The problem is exacerbated by a lack of clear labeling. European Union legislation is lenient regarding sodium content in dietary supplements, requiring mandatory labeling in only 23% of the 71 analyzed samples. Researchers found an average of 0.64 grams of salt per tablet, with some products containing significantly more.

For consumers advised to limit salt intake, such as those with high blood pressure or heart and kidney conditions, regular use of these tablets could lead to consuming approximately 1.8 grams of salt daily. This is over a third of the threshold that increases risks for cardiovascular diseases. Researchers are advocating for more transparent labeling and the development of lower-sodium products.

Because we consume effervescent tablets as a drink and they usually don't have a salty taste, consumers don't notice such salt intake at all.
