Nature's Way Calcium & Magnesium Mineral Complex
Brand: Nature's Way · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Nature's Way Calcium & Magnesium Mineral Complex provides calcium, a mineral essential for bone health and nerve function. Our assessment: this product can be a useful supplement for supporting your bone density and neuromuscular relaxation, but you must be aware of significant safety considerations and potential medication interactions [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, meaning it helps deposit minerals into your bone matrix to keep them strong [NIH ODS]. Additionally, calcium plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after contraction [NIH ODS]. This product combines calcium with magnesium, which also supports muscle function.
Safety profile
Data not available for this specific product's side effects. However, based on the calcium ingredient, high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium 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]. The FDA has received 592,059 total adverse event reports across all supplement categories, but this number is not specific to this product [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your total dietary calcium intake from food and other supplements. Do not exceed the Tolerable Upper Intake Level without medical supervision. To avoid medication interactions, take this supplement at least two hours apart from any medications you are prescribed [NIH ODS]. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before use [NIH ODS].
