Nordic Naturals Nordic Probiotic Sport

Our assessment

The evidence shows that Nordic Naturals Nordic Probiotic Sport is a supplement whose primary active ingredient listed in the provided data is calcium. Our assessment is that while calcium is essential for health, you should be aware of the specific risks and interactions associated with this mineral. The data does not provide specific efficacy studies or ingredient amounts for the probiotic itself, so we must focus on the calcium component for which data is available.

How it works

Calcium functions as a master regulator for your body's structure and signaling. It supports bone mineralization and density, and it is critical for neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the key that helps your muscles relax after contracting and ensures your nerves can send messages properly throughout your body.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplements in the database, though the specific count for this product is not available. Regarding calcium, the data warns that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in your 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

You should consult your healthcare provider before starting this supplement, especially if you take any of the medications listed above or have a history of kidney problems or heart disease. For specific dosing and safety guidance, data for this product is not available to provide a confident recommendation.
