Brand: Sundown Naturals · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Sundown Naturals Amino Acid Complex With Calcium provides calcium, a mineral essential for bone health. Our assessment is that this product can help you meet your calcium needs, but you must be careful with total intake from all sources [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. Taking too much can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and poor kidney function [NIH ODS] [FDA data]. Calcium can also reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by checking your total daily calcium intake from food and other supplements. Do not exceed the upper limit without medical supervision. Take this product separately from any prescription medications by at least 2 hours to avoid absorption issues [NIH ODS].
