ShopRite Magnesium 250 mg
Brand: ShopRite · Form: SUPPLEMENT FORM, OTHER [E0172] On Market
Our assessment
The evidence shows that this product contains calcium, not magnesium. The data provided indicates that calcium is essential for strong bones and proper nerve function, but the specific dose for this product is listed as 250 mg on the label [NIH ODS]. You should verify the ingredient label carefully, as the product name suggests it contains magnesium, but the data only describes calcium.
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization by helping deposit minerals into your skeleton, and it plays a key role in neuromuscular relaxation, allowing your muscles and nerves to signal properly [NIH ODS]. Think of it as the building block for your bones and a quieting signal for your nerves.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels 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] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our assessment: You should first confirm whether you need calcium or magnesium, as the product name does not match the ingredient data provided. If you choose to take this supplement, take it with food and separate it from the listed medications by at least two hours [NIH ODS]. Stick to the label dose of 250 mg and do not exceed the RDA without consulting your doctor.
