KAL Magnesium Citrate 160 mg Powder
Brand: KAL · Form: POWDER [E0162] On Market
Our assessment
Our assessment: This product contains calcium, not magnesium citrate. The evidence shows that calcium is a critical mineral for bone health, but you must be cautious with dosing. The RDA for most adults is 1,000 mg daily, though needs increase with age [NIH ODS].
How it works
Think of calcium as a structural builder — it supports bone density and mineral deposition, and it also helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for this ingredient category. Side effects from high blood and urine calcium levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS]. Some research also suggests high intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Start with food sources first. If you supplement, do not exceed 2,000 mg total from food and supplements daily. Take calcium separately from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, as calcium can reduce their absorption [NIH ODS]. Data not available for magnesium citrate in this specific product — verify the label before use.
