Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function. However, we must be clear: the total adverse event reports for all products in this category number 592,059, and this specific formulation requires careful dosing consideration [FDA data]. You should not exceed the recommended daily allowance without a healthcare provider’s guidance.
How it works
Think of calcium as a structural builder and signal messenger for your body. It supports bone density and mineral deposition, which is critical for skeletal strength. Additionally, it plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
High calcium intakes may increase the risk of heart disease and prostate cancer based on some research. Extremely high levels in the blood and urine can lead to 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]. You should also be aware that calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your total calcium intake from food and other supplements. Do not exceed the Tolerable Upper Intake Level unless directed by your doctor. Take calcium supplements separately from the medications listed in the interactions section by at least two hours to ensure proper absorption [NIH ODS].
