Cellucor Alpha Amino Xtreme Watermelon

Our assessment

The evidence shows that the primary ingredient in Cellucor Alpha Amino Xtreme Watermelon is Calcium, a mineral essential for bone health and muscle function. However, based on the data provided, we cannot evaluate the full formula or its specific efficacy for athletic performance because ingredient amounts and other active components are not listed. Our assessment is that while calcium is a well-studied mineral, relying on this product without a complete ingredient profile limits our ability to make a confident recommendation for your specific needs [NIH ODS].

How it works

Think of calcium as a structural builder and a signal regulator. It supports bone mineralization, which helps maintain bone density, and it plays a role in neuromuscular relaxation, allowing your muscles to contract and nerves to signal properly after exercise [NIH ODS].

Safety profile

The FDA has received a total of 592,059 adverse event reports across all dietary supplements, though specific report counts for this product are not available. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium 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]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Data not available to recommend this specific product due to missing ingredient amounts and a full ingredient list. For calcium supplementation, start by assessing your dietary intake. Most adults need 1,000–1,200 mg daily from food and supplements combined, but do not exceed the upper limit without medical guidance. Always take calcium supplements with food and separate from thyroid medication or antibiotics by at least 2 hours [NIH ODS].
