GNC Potassium Plus 99 mg
Brand: GNC · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that GNC Potassium Plus 99 mg is a potassium supplement, but the data provided does not include any specific information about potassium itself. Instead, the available ingredient data is for calcium, which is listed as a mineral in the NIH ODS section. Based solely on the data supplied, we cannot confirm the benefits, mechanism, or safety profile for the potassium content in this product. You should be aware that the product label may list other ingredients, but no specific ingredient data for potassium is available in the provided information.
How it works
According to the data provided, the ingredient calcium supports bone mineralization by promoting bone density and mineral deposition, and it aids neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS]. However, this information is for calcium, not potassium. For the potassium content in this specific product, data on how it works is not available.
Safety profile
Data not available for potassium specifically. For the calcium ingredient, some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. The FDA has received a total of 592,059 adverse event reports for all supplements, but the number specific to this product is not provided [FDA data].
Our recommendation
Based on the data provided, we cannot recommend GNC Potassium Plus 99 mg for potassium supplementation because no specific data on potassium's benefits, safety, or interactions is available. If you are considering a potassium supplement, consult your healthcare provider to discuss your needs and potential risks. For the calcium ingredient, be aware of possible interactions: calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Without complete data on the potassium component, our recommendation is to seek a product with transparent, evidence-backed ingredient information.
