MusclePharm Shred Matrix
Brand: MusclePharm · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that MusclePharm Shred Matrix contains calcium, a mineral essential for bone health and nerve function. However, we must be clear: beyond this single ingredient, data for the other components in this product is not available. Based solely on the calcium content, this supplement may support bone mineralization, but you should not expect dramatic results for weight loss or body composition changes from this ingredient alone [NIH ODS].
How it works
Think of calcium as a structural support and a signal messenger. It works by supporting bone density and mineral deposition, and it also helps your muscles relax and your nerves send signals properly [NIH ODS]. While these are vital functions, they do not directly target fat loss or shredding muscle definition.
Safety profile
FDA has received 592,059 total adverse event reports across all supplements, though specific reports for MusclePharm Shred Matrix are not available. For calcium specifically, high intakes can increase the risk of heart disease, prostate cancer, and can cause poor muscle tone, 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
Start by getting your calcium from food sources like dairy, leafy greens, and fortified products. If you take this supplement, do not exceed the recommended dose on the label. Be aware of the potential side effects and medication interactions. For weight loss or body composition goals, this product is unlikely to provide the results you may be seeking. Consult your healthcare provider before starting any new supplement, especially if you take prescription medications [NIH ODS].
