Natrol Melatonin 1 mg
Brand: Natrol · Form: TABLET [E0155]
Our assessment
Our assessment: Calcium is a foundational mineral for bone health, but the data shows that you need to be careful with dosing. The NIH Office of Dietary Supplements confirms that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, the evidence is clear that more is not always better, and you should aim to get your calcium from food first.
How it works
Think of calcium as the building block for your bones and a signal transmitter for your nerves. It helps your body deposit minerals into your skeleton to maintain bone density, and it supports muscle relaxation and nerve signaling [NIH ODS]. Without enough calcium, your body will pull it from your bones, which can weaken them over time.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all dietary supplements. For calcium specifically, high intakes are linked to serious risks. High levels of calcium 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]. Additionally, calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Do not exceed the recommended dietary allowance without a doctor's guidance. Get your calcium from food sources like dairy, leafy greens, and fortified foods whenever possible. If you take a supplement, separate it from your thyroid medication or antibiotics by at least two hours.
