Nature's Sunshine Magnesium Complex
Brand: Nature's Sunshine · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Nature's Sunshine Magnesium Complex is formulated to support bone health and nerve function. The key ingredient, calcium, is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that this product contains calcium, not magnesium, as the primary active mineral based on the data provided.
How it works
Think of calcium as a structural and signaling powerhouse. It supports bone density by depositing minerals into your skeleton and helps your muscles relax and nerves communicate properly [NIH ODS]. This makes it relevant for maintaining strong bones and healthy nerve function throughout your body.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase risks for heart disease and prostate cancer [NIH ODS]. Side effects from very high levels include constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Start by checking your current calcium intake from food and other supplements before adding this product. The data shows you should be cautious with high doses due to potential heart and kidney risks [NIH ODS]. If you take prescription medications, consult your doctor about timing to avoid absorption issues [NIH ODS]. For most adults, a balanced diet provides adequate calcium, so use this supplement only if you have a confirmed need.
