NOW Coral Calcium 1000 mg
Brand: NOW · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that calcium is essential for bone health, but the form in NOW Coral Calcium 1000 mg does not offer unique benefits over standard calcium supplements. The core ingredient, calcium, supports bone mineralization and neuromuscular function [NIH ODS]. However, the coral source does not change how your body uses the mineral.
How it works
Think of calcium as the building block for your skeleton. It works through bone mineralization to support bone density and mineral deposition, and it also supports muscle relaxation and nerve signaling [NIH ODS]. If you take this supplement, you are primarily getting a calcium dose, which your body uses the same way regardless of the source.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though specific data for this product is not available. You should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your total daily calcium intake from food and other supplements. If you are deficient, a standard calcium supplement is equally effective. For most adults, the goal is 1,000 mg to 1,200 mg total daily calcium from all sources [NIH ODS]. Take calcium with food and separate it from thyroid medication or antibiotics by at least four hours [NIH ODS]. If you have a history of kidney stones or heart concerns, consult your doctor before starting this supplement.
