Our assessment
The evidence shows that calcium is a foundational mineral for bone health, but it is not a supplement to take casually. Our assessment is that while the Pure Encapsulations Women's Pure Pack provides calcium in the citrate form—which is generally well-absorbed—you need to be very careful with your total daily intake and timing. Data on the exact dosage in this specific pack is not available, so you must check the label to confirm the amount.
How it works
Think of calcium as the building block for your skeleton. It supports bone mineralization and density, which is critical for preventing fractures as you age [NIH ODS]. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplement categories. Specific risks for calcium include constipation, nausea, and weight loss [NIH ODS]. More serious concerns involve high calcium intakes potentially increasing the risk of heart disease and prostate cancer [NIH ODS]. Very high levels in the blood can cause poor muscle tone, poor kidney function, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. You should also know that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by checking the label of your Pure Pack to see exactly how much calcium you are getting. Be sure to add up all calcium from food, other supplements, and this pack. Do not exceed the Tolerable Upper Intake Level of 2,500 mg per day from all sources. Take calcium supplements separately from your thyroid medication and antibiotics by at least 2 hours [NIH ODS]. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before taking this supplement [NIH ODS].
