Our assessment
The evidence shows that this product contains calcium as a primary mineral ingredient. Based on the data available, we cannot assess the specific combination of amino acids in this formula, as no ingredient breakdown beyond calcium is provided. For the calcium component, the data shows it supports bone density and muscle relaxation [NIH ODS]. However, you should be aware of the potential risks and interactions associated with calcium supplementation before adding this to your routine.
How it works
Calcium acts as a master regulator for your body's structural and signaling systems. It supports bone mineralization, helping to maintain bone density, and it also plays a role in neuromuscular relaxation, aiding in proper muscle function and nerve signaling [NIH ODS]. Think of it as a key building block that your body uses every day for both strength and communication between cells.
Safety profile
The FDA has received a total of 592,059 adverse event reports for products in this category, though this number covers all reports and not just those for this specific supplement [FDA data]. The data indicates that high calcium 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 [NIH ODS]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for a specific dosing recommendation for this product. Before taking this supplement, review your total calcium intake from all sources, including food and other supplements.

Given the potential risks from high calcium levels, it is best to discuss your use of this product with a healthcare provider to ensure it is safe and appropriate for you [NIH ODS].
