Swanson Premium Brand Potassium (Gluconate) 99 mg
Brand: Swanson Premium Brand · Form: CAPSULE [E0159]
Our assessment
Our assessment: Potassium is an essential mineral that supports nerve signaling and muscle contraction [NIH ODS]. The evidence shows that this 99 mg dose of potassium gluconate is a modest supplement, providing about 2% of the daily value for potassium. This is a low-dose formulation, so you should not expect dramatic effects on blood pressure or heart health from this product alone [NIH ODS].
How it works
Think of potassium as a cellular messenger that helps your nerves transmit signals and your muscles contract properly [NIH ODS]. It works alongside sodium to maintain fluid balance and is critical for maintaining a normal heart rhythm [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements and medications. Data not available for specific side effect report counts for this product. High potassium intake can be dangerous for people with kidney disease or those taking certain blood pressure medications [NIH ODS].
Our recommendation
Start by getting potassium from food sources like bananas, potatoes, and spinach. If you choose to supplement, this 99 mg dose is safe for most healthy adults, but do not exceed recommended amounts without medical supervision [NIH ODS].
