NutraSport Performance Turmeric

Our assessment

The evidence shows that the primary active ingredient in this product is calcium, a mineral essential for bone health. Our assessment: For most adults, meeting your calcium needs through food is preferable, and supplementation should be approached with caution. The data confirms that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS].

How it works

Think of calcium as a building block for your skeleton and a messenger for your nerves and muscles. It works by depositing into bone tissue to maintain density, and it helps your muscles relax and your nerves send signals properly after they fire [NIH ODS].

Safety profile

FDA received a total of 592,059 adverse event reports across all supplement categories, though specific counts for this product are not available. The data shows that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels 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].

Our recommendation

Start by assessing your dietary calcium intake from dairy, leafy greens, and fortified foods. Do not exceed the Tolerable Upper Intake Level without medical supervision. Take calcium supplements separately from any medications listed in the safety profile by at least two hours [NIH ODS]. Data not available for specific dosing of this product. Speak with your healthcare provider before starting this supplement, especially if you have kidney issues or take prescription medications.
