Natrol Melatonin 3 mg
Brand: Natrol · Form: TABLET [E0155]
Our assessment
The evidence shows that while calcium is essential for your health, you need to be cautious with dosing. For a general audience, the data confirms that calcium supports bone density and muscle relaxation [NIH ODS]. However, high intakes are linked to risks, so you should not exceed recommended levels without medical guidance.
How it works
Think of calcium as a structural builder for your bones and a signal messenger for your nerves and muscles. It helps your body deposit minerals into bone tissue and supports proper muscle contraction and nerve signaling [NIH ODS].
Safety profile
FDA has received 592,059 total adverse event reports across all products, though data for this specific supplement is limited. High levels of calcium in your blood and urine can cause poor muscle tone, 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 high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Start by getting your calcium from food first. If you need a supplement, choose one with no more than 500-600 mg per dose and take it with food. Avoid taking calcium with bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, as it can reduce their absorption [NIH ODS].
