Our assessment
The evidence shows that the calcium in NOW Tri-3D Omega supports bone health, but you need to be aware of important safety considerations. Our assessment is that this supplement can be part of a healthy routine, provided you manage your total calcium intake carefully and do not exceed recommended limits [NIH ODS].
How it works
Think of calcium as a building block for your bones. Its primary role is bone mineralization, helping to maintain bone density and strength. It also supports neuromuscular relaxation, aiding in proper muscle and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Symptoms of excessive calcium include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and poor kidney function [NIH ODS] [FDA data]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by calculating your total daily calcium intake from food and all supplements to avoid exceeding the tolerable upper limit. Take this supplement with food and separate it from any medications listed above by at least 2 hours. If you have a history of kidney stones, heart disease, or take thyroid medication, consult your healthcare provider before use [NIH ODS].
