Puritan's Pride Albion Chelated Magnesium 400 mg

Brand: Puritan's Pride · Form: SUPPLEMENT FORM, OTHER [E0172]

Our assessment

The evidence shows that calcium supports bone health and muscle relaxation, but the specific product you asked about — Puritan's Pride Albion Chelated Magnesium 400 mg — contains magnesium as its primary ingredient. Data for magnesium specifically is not available in the provided materials. For the ingredient calcium, which is listed in our data, the benefits are well-documented, but you must be cautious with dosing and interactions [NIH ODS].

How it works

Think of calcium as a structural builder and nerve relaxer. It supports bone density through bone mineralization and helps your muscles relax by aiding nerve signaling [NIH ODS]. This dual role makes it essential for both your skeleton and your nervous system.

Safety profile

FDA received 592,059 total adverse event reports across all supplements in the database. For calcium specifically, high intakes may 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].

Our recommendation

You should be aware that calcium supplements can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Before taking any calcium product, consult your healthcare provider to review your current medications and overall health status. Data not available for the specific magnesium product you mentioned, so we cannot make a recommendation for that supplement.
