Nature's Sunshine Coral Calcium

Our assessment
The evidence shows that calcium is essential for bone health, but our assessment of Nature's Sunshine Coral Calcium is that it should be evaluated with caution. While calcium supports bone density and neuromuscular function [NIH ODS], you must be aware that high intakes may increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder—it supports bone mineralization and mineral deposition, giving your skeleton strength [NIH ODS]. It also acts as a nerve signal regulator, helping your muscles relax and nerves communicate properly [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports for this product category. Specific side effects from high calcium levels include 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]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available on the specific dose in this product. We recommend you get your calcium from food first. If you take a supplement, keep total daily intake from all sources at or below the RDA. Check with your doctor before starting, especially if you take medications for osteoporosis, thyroid issues, or infections [NIH ODS].
