GNC Pro Performance Amino Burst 3000
Brand: GNC Pro Performance · Form: TABLET [E0155]
Our assessment
The evidence shows that GNC Pro Performance Amino Burst 3000 contains calcium as a key ingredient. Based on the available data, calcium is essential for bone health and muscle function, but the supplement’s overall effectiveness depends on your individual needs and diet [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone density and mineral deposition, which helps keep your bones strong. Calcium also plays a role in neuromuscular relaxation, aiding muscle relaxation and nerve signaling after exercise [NIH ODS].
Safety profile
From FDA adverse event data, there have been 592,059 total reports across all supplements. For calcium specifically, 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 [FDA data] [NIH ODS].
Our recommendation
Before starting this supplement, check your daily calcium intake from food. Calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, so take it separately from these drugs [NIH ODS]. Start with a low dose and monitor for any side effects. Data not available on the exact calcium dose per serving in this product.
