Puritan's Pride Magnesium 250 mg
Brand: Puritan's Pride · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that Puritan's Pride Magnesium 250 mg is a standard supplement, but the data provided focuses on calcium, not magnesium. For calcium, our assessment is that it plays a critical role in bone health and nerve function, but you need to be careful with dosing. The data confirms that high calcium intakes might increase the risk of heart disease and prostate cancer, and that high levels in the blood can cause serious issues [NIH ODS].
How it works
Think of calcium as a structural builder and signaler for your body. It supports bone density and mineral deposition, which is essential for keeping your skeleton strong. It also supports muscle relaxation and nerve signaling, helping your muscles and nerves communicate properly [NIH ODS].
Safety profile
Data not available for Puritan's Pride Magnesium 250 mg specifically. However, based on the calcium data provided, side effects from high calcium levels include 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 received a total of 592,059 adverse event reports across all supplements, but specific count for this product is not provided [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Since the data provided is for calcium rather than magnesium, we cannot give a specific recommendation for Puritan's Pride Magnesium 250 mg. For calcium, we recommend sticking to the RDA and getting your levels checked by a doctor. Do not exceed recommended doses due to the serious risks of high calcium intake, and always take calcium supplements separately from medications like antibiotics or thyroid medicine [NIH ODS].
