Swanson Premium Brand Potassium Aspartate
Brand: Swanson Premium Brand · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Swanson Premium Brand Potassium Aspartate is a supplement that requires careful consideration. The primary ingredient data available is for calcium, not potassium aspartate, so our assessment is based on the broader mineral category. For many people, calcium from food is preferable, and we cannot confirm the specific benefits of this product's form based on the provided data.
How it works
Think of calcium as a structural builder and nerve communicator. It supports bone density and mineral deposition, and it also helps your muscles relax and your nerves send signals properly [NIH ODS]. Without this mineral, your body would struggle to maintain a strong skeleton and a calm, responsive nervous system.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on the specific side effects of potassium aspartate is not available.
Our recommendation
Data is not available to confirm that this specific potassium aspartate product is effective or safe for the general population. Because the data provided focuses on calcium, not potassium aspartate, we cannot recommend this product. If you are considering a calcium supplement, consult your doctor first, especially if you take any medications or have a history of kidney issues or heart disease [NIH ODS]. It is safer to get your nutrients from food whenever possible.
