Nutra Sport Omega-3

Our assessment

The evidence shows that this product contains calcium, a mineral critical for bone health. However, the data for this specific product is limited. Our assessment: you should understand the well-documented benefits and risks of calcium before using this supplement. The FDA has received 592,059 total adverse event reports for products containing calcium, which is a significant number to consider [FDA data].

How it works

Calcium is a master regulator for your body's structure and function. It supports bone mineralization, helping you maintain strong bone density and mineral deposition [NIH ODS]. Additionally, calcium plays a key role in neuromuscular relaxation, meaning it helps your muscles relax and supports healthy nerve signaling [NIH ODS]. Think of it as the building block your body uses every day to keep your skeleton sturdy and your nerves communicating properly.

Safety profile

Safety data shows important cautions. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
