MRM Cal-Mag-Zinc Liquid Strawberry
Brand: MRM · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that MRM Cal-Mag-Zinc Liquid Strawberry provides three essential minerals in a convenient liquid form. The key ingredient, calcium, supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that some research suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a master builder for your skeleton — it supports bone density and mineral deposition, while also helping your muscles relax and nerves signal properly [NIH ODS]. This liquid formula may be easier for you to absorb if you have difficulty swallowing pills. The strawberry flavor is designed to improve palatability.
Safety profile
FDA received 592,059 total adverse event reports across all supplement categories [FDA data]. For calcium specifically, high levels in your 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start with the serving size listed on the label. You should take calcium supplements separately from your thyroid medication or antibiotics by at least two hours to avoid absorption issues [NIH ODS]. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before use. Data not available for specific dosing of magnesium and zinc in this product.
