Our assessment
The evidence shows that the calcium in NOW Tri-3D Omega is essential for bone health, but the data also points to significant risks at high intakes. We recommend focusing on your total daily calcium intake from all sources, as exceeding safe limits can pose health dangers [NIH ODS].
How it works
Calcium acts as a foundation mineral for your body. It supports bone mineralization and density, and plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in the blood and urine 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. It can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on the specific dosage of calcium in this product is not available, so we cannot confirm if it is appropriate for you. Consult your doctor before use [NIH ODS].
