NOW Coral Calcium Plus
Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that NOW Coral Calcium Plus primarily provides calcium, a mineral essential for bone health. Our assessment: if you are looking to support your bone density, this supplement can be a source of calcium, but it is important to know that the benefits and risks are the same as any standard calcium supplement. The data does not support unique health benefits from the "coral" source itself [NIH ODS].
How it works
Think of calcium as the building block for your skeleton. It supports bone mineralization and density. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after contraction [NIH ODS].
Safety profile
FDA received 592059 total adverse event reports across all supplements, though this number is not specific to this product. For calcium specifically, safety concerns include that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in your blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
If you are using this for bone health, ensure your total daily calcium intake from food and supplements does not exceed safe limits. Be aware that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take this supplement at least two hours apart from these medications [NIH ODS]. Data not available for specific benefits unique to coral calcium over other forms.
