Nature Made Magnesium 250 mg
Brand: Nature Made · Form: TABLET [E0155] On Market
Our assessment
Our assessment: The evidence for calcium is strong for bone health, but you need to be cautious with dosing. The data shows that 250 mg of magnesium from this product is a standard supplemental amount, but the primary ingredient we have data on is calcium [NIH ODS]. For calcium, the RDA for most adults is 1,000–1,200 mg daily from all sources, so you should consider your total dietary intake [NIH ODS].
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization and density, and it also helps with neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the structural material for your skeleton and a key player in how your muscles and nerves communicate.
Safety profile
FDA received 592,059 total adverse event reports for all dietary supplements, but specific side effect counts for this product are data not available. For calcium specifically, some research suggests that high 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Start by assessing your total daily calcium intake from food and other supplements. Do not exceed 2,000–2,500 mg total per day from all sources [NIH ODS]. Take calcium supplements with food for best absorption, and separate them from medications like thyroid hormone or antibiotics by at least 2 hours [NIH ODS]. For this specific Nature Made product, the 250 mg of magnesium is the featured ingredient, but we lack specific data on that ingredient's effects in this product.
