Our assessment
The evidence shows that calcium is a critical mineral for your health, but it requires careful management. The data confirms its role in bone density and nerve function, yet also highlights serious risks from excessively high intake [NIH ODS].
How it works
Think of calcium as a key structural component for your bones and teeth, providing the framework for bone mineralization. It also acts as a signaling molecule that supports muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for all supplements, though specific report counts for calcium alone are not available from this data. High calcium intakes may increase the risk of heart disease and prostate cancer. Extremely high blood and urine levels 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].
Our recommendation
You should be cautious with calcium supplementation. Because calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, take calcium supplements at a different time than these drugs [NIH ODS]. Data not available for the specific GNC Amino Acid Formula ingredients, so you should consult your pharmacist or doctor before starting any new supplement.
