Our assessment
The evidence shows that calcium is essential for your bone health and nerve function, but the specific product NOW Coral Calcium Plus does not have enough data for us to recommend it over standard calcium supplements. Our assessment: you are better off choosing a well-studied calcium source with a clear dosage [NIH ODS].
How it works
Think of calcium as the building block for your skeleton. It supports bone mineralization and density, and it plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Your body needs a steady supply to keep your muscles and nerves working properly.
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 [NIH ODS]. Side effects from high calcium levels include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on the specific safety profile of NOW Coral Calcium Plus is not available.
Our recommendation
We recommend you get your calcium from food sources or a standard calcium supplement with a verified dose. If you take a calcium supplement, be aware of the potential interactions with your medications and avoid exceeding the recommended daily intake [NIH ODS]. For NOW Coral Calcium Plus, data on its specific benefits or risks is not available, so we cannot recommend it over other options.
