Our assessment
The evidence shows that calcium is a foundational mineral for bone health, but it comes with important safety considerations. For most adults, getting calcium from food is preferred, and supplementation should be approached with caution. Data not available on the specific product Natural Factors Zinc Chelate 25 mg, as the provided data focuses on calcium as an ingredient.
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, which is critical for maintaining strong bones as you age [NIH ODS]. Calcium also acts as a nerve relaxant, supporting muscle relaxation and proper nerve signaling throughout your body [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Very 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 urination, 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 by assessing your dietary calcium intake from food sources like dairy, leafy greens, and fortified foods. If you do supplement, choose a dose that brings your total daily intake to the recommended level, and take it separately from other medications by at least two hours. Always consult your healthcare provider before starting, especially if you have a history of kidney stones or heart concerns [NIH ODS].
