Nature's Sunshine Magnesium Complex
Brand: Nature's Sunshine · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that magnesium, as found in Nature's Sunshine Magnesium Complex, plays a key role in over 300 biochemical reactions in your body, including nerve transmission and muscle relaxation. However, we must be clear: the specific ingredient data provided is for calcium, not magnesium. Based on the data available, calcium is essential for bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural builder and a signal messenger. It supports bone density by depositing minerals into your skeleton, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. For the magnesium component specifically, data is not available on its mechanism from the provided sources.
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements, but specific data for this product is not available. For calcium, high intake can cause constipation, nausea, and abnormal heart rhythms. There is also a potential risk of heart disease and prostate cancer with high levels [NIH ODS]. You should be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Start by consulting your healthcare provider to determine if you need additional magnesium or calcium. Since we lack specific data on the magnesium content and ratios in this product, and because calcium has known medication interactions, it is safest to get a personalized assessment before taking this supplement. Choose a product where you can verify the exact elemental amounts of each mineral [NIH ODS].
