Our assessment
The evidence shows that calcium is a well-studied mineral with clear benefits for bone health, but the specific product you are asking about — Nature's Sunshine Calcium-Magnesium — has a data gap for its exact ingredient amounts. Our assessment is that calcium supports bone mineralization and neuromuscular relaxation, which are essential for your daily function [NIH ODS]. However, you must be careful with dosing because the label specifics are not available here.
How it works
Think of calcium as a structural building block for your skeleton and a signaling molecule for your nerves and muscles. It helps deposit minerals into your bone matrix to maintain density and supports muscle relaxation after contraction [NIH ODS]. Magnesium often works alongside calcium to balance these effects, though data on the magnesium content in this specific product is not available.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels in the 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]. Calcium can also reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by checking your current calcium intake from food and other supplements. Because the exact dose per serving for Nature's Sunshine Calcium-Magnesium is not provided, we cannot give a specific daily amount. Data not available on the magnesium content means you should not assume a balanced ratio. We recommend choosing a product with a clear label and taking calcium with food to improve absorption. Avoid exceeding 2,000 mg total calcium per day from all sources, and separate calcium doses from thyroid or antibiotic medications by at least 4 hours [NIH ODS].
