GNC Herbal Plus Turmeric Sport
Brand: GNC Herbal Plus · Form: CAPSULE [E0159]
Our assessment
The evidence shows that while the product is marketed as GNC Herbal Plus Turmeric Sport, the only ingredient data provided is for Calcium. Based on this, our assessment is that this product provides a significant dose of calcium, but data for turmeric or other active ingredients is not available. You should be aware that calcium supports bone health, but the data does not confirm any specific benefit for sports performance from this product.
How it works
Think of calcium as a structural builder and nerve communicator. It supports bone density and mineral deposition, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. Without data on the turmeric component, we cannot explain how that specific ingredient might work in this formula.
Safety profile
FDA received 592059 total adverse event reports across all products. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. 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].
Our recommendation
Our recommendation is to proceed with caution. Since data on the turmeric content is not available, you are essentially taking a calcium supplement. Do not exceed the recommended dosage on the label, and be aware that calcium supplements may interact with medications you take. If you are looking for turmeric's specific benefits, data for this product is not available to support that use. Consult your healthcare provider before starting this supplement, especially if you take prescription medications [NIH ODS].
