Nature's Way Calcium & Magnesium Mineral Complex
Brand: Nature's Way · Form: CAPSULE [E0159] On Market
Our assessment
Our assessment: A calcium and magnesium mineral complex can be a practical way to support bone health and muscle function, but you need to be mindful of the specific doses and potential interactions. The evidence shows that calcium is critical for bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should not exceed the recommended intake without medical supervision, as the data on high calcium intake raises important safety concerns.
How it works
Think of calcium as a structural builder for your bones and a signal conductor for your nerves and muscles. It supports bone density and mineral deposition, while also helping your muscles relax and your nerves send signals properly [NIH ODS]. Magnesium often works alongside calcium to support these processes, though specific data for the combination is not available here.
Safety profile
FDA has received 592,059 total adverse event reports for products like this, though this number covers all supplements in the database, not just this specific product [FDA data]. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels of calcium in the blood can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. You should also be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: This product can be a reasonable choice if you need to supplement both calcium and magnesium, but check the label for exact amounts per serving. Take calcium supplements at a different time than any medications listed in the interactions above. Do not exceed the total daily recommended intake from all sources (food and supplements) without your doctor's guidance, given the potential risks of high calcium intake [NIH ODS]. If you have a history of kidney stones, heart disease, or prostate cancer, speak with your physician before starting this supplement.
