Our assessment
The evidence shows that this product contains calcium, which plays a key role in bone health. However, based on the data provided, we cannot assess the specific benefits of GNC Herbal Plus Turmeric Sport because the formulation details are not fully available. The primary active ingredient data we have is for calcium, not turmeric [NIH ODS].
How it works
If this product provides calcium, it works through bone mineralization, supporting bone density and mineral deposition in your skeleton. It also aids in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS]. Data on how turmeric specifically works in this product is not available.
Safety profile
FDA received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
We recommend caution. Because the specific turmeric ingredient data is missing, and calcium carries notable risks at high doses, you should consult your healthcare provider before taking this product. If you choose to use it, be aware that calcium can reduce absorption of bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on the exact dosage and safety of the turmeric component is not available.
