Our assessment
The evidence shows that calcium is an essential mineral for bone health, but supplementation requires careful consideration of dosage and timing. Our assessment is that while calcium supports bone density and nerve signaling, it is not a supplement to take casually due to potential risks and medication interactions [NIH ODS].
How it works
Calcium acts as a key structural component for your bones and teeth. It supports bone mineralization and helps with neuromuscular relaxation, allowing your muscles to relax and your nerves to signal properly [NIH ODS]. Think of it as the building block that keeps your skeleton strong and your nervous system communicating smoothly.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine calcium 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]. Side effect report counts for calcium alone are not available.
Our recommendation
We recommend getting your calcium intake assessed by a healthcare professional before supplementing. Be aware that calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for the specific NOW Tri-Amino product label details. Start with dietary sources first, and only supplement if a blood test or dietary analysis confirms a deficiency.
