NOW Calcium & Magnesium Softgel
Brand: NOW · Form: SOFTGEL CAPSULE [E0161]
Our assessment
The evidence shows that calcium is essential for bone health, but it must be taken with care. For the specific product NOW Calcium & Magnesium Softgel, data on the exact dosage per softgel is not available. However, the general data on calcium is clear: it supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a key player in muscle function. It works by supporting bone density and mineral deposition, and it helps your muscles relax and your nerves signal properly [NIH ODS].
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. Signs of excessive calcium include 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
Start by reviewing the label for the exact calcium dose per softgel. Be aware that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine — take these at least two hours apart [NIH ODS]. Because the specific dose is not available here, we recommend consulting your healthcare provider to determine if this product fits your needs.
