MuscleTech Performance Series Amino Build Next Gen Watermelon

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health and muscle function. Based on the data provided, we cannot confirm the specific amount of calcium in each serving of MuscleTech Performance Series Amino Build Next Gen Watermelon, as the label details are marked "See label." For a general audience, calcium is a well-studied nutrient, but its benefits depend heavily on your total dietary intake [NIH ODS].

How it works

Think of calcium as a key building block for your bones and a signal messenger for your muscles. It supports bone mineralization, helping to maintain bone density, and plays a role in neuromuscular relaxation, which helps your muscles relax after contracting [NIH ODS]. This is why adequate calcium is often linked to both skeletal strength and proper muscle function.

Safety profile

Data not available for this specific product's side effect reports. The FDA received a total of 592,059 adverse event reports across all dietary supplements, but specific counts for this product are not provided. From the general data on calcium, high intakes may increase the risk of heart disease and prostate cancer. Very high blood calcium levels can cause poor muscle tone, constipation, nausea, weight loss, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS].

Our recommendation

Our assessment: You should only use this product if you know you need additional calcium beyond what you get from food. Check the label for the exact calcium amount per serving when you purchase it. Be aware that calcium can reduce the absorption of medications like bisphosphonates, certain antibiotics, and levothyroxine, so take this supplement at a different time than those drugs [NIH ODS]. For most adults, meeting calcium needs through diet is preferred, and supplements are best used to fill a verified gap. If you have a history of kidney stones or heart conditions, consult your doctor before starting [NIH ODS].
