GNC TriFlex Joint, Bone & Muscle Tropical Fruit
Brand: GNC TriFlex · Form: POWDER [E0162]
Our assessment
The evidence shows that GNC TriFlex Joint, Bone & Muscle Tropical Fruit contains calcium, a mineral critical for bone health. Our assessment is that this product may help support bone density, but it is not a complete solution for joint pain or muscle recovery, and you should be aware of the specific risks associated with calcium supplementation [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It supports bone mineralization and density by helping deposit minerals into your skeletal structure. It also plays a role in neuromuscular relaxation, which means it helps your muscles relax and nerves signal properly after activity [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for products in this category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in the blood can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for specific dosage of calcium in this product. We recommend you check the label for the exact amount. If you take calcium, do not exceed 2,500 mg per day total from food and supplements. Take it with food and separate from thyroid or antibiotic medications by at least 2 hours [NIH ODS].
