Solgar Magnesium Citrate
Brand: Solgar · Form: TABLET [E0155]
Our assessment
The evidence shows that Solgar Magnesium Citrate is a well-absorbed form of magnesium for supporting muscle relaxation and nerve signaling. However, based on the data provided, the active ingredient in this product is calcium, not magnesium. The data confirms that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. Our assessment: you should verify the label of your specific product, as the ingredient data available here points to calcium, not magnesium citrate.
How it works
Think of this mineral as a master regulator for your muscles and nerves. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves signal properly [NIH ODS]. This mechanism is key for maintaining strong bones and preventing muscle cramps.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, 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]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Report count for this specific product is not available.
Our recommendation
Start by confirming your product label — the data indicates this contains calcium, not magnesium. If you are taking this for magnesium, choose a product explicitly labeled as magnesium citrate. Do not exceed the RDA for calcium without medical supervision, and separate calcium supplements from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin by at least 2 hours [NIH ODS]. Consult your pharmacist for personalized dosing.
