Pure Encapsulations Mineral 650 (without Copper & Iron)
Brand: Pure Encapsulations · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is a well-studied mineral, but it is not for everyone. While it is essential for bone health, taking a high-dose supplement like Pure Encapsulations Mineral 650 (without Copper & Iron) carries real risks that you need to weigh carefully. The data shows that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. This is not a supplement to take casually.
How it works
Think of calcium as a building block for your skeleton. It supports bone mineralization and density by depositing minerals into your bone matrix [NIH ODS]. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after they fire [NIH ODS]. Without enough calcium, your body will leach it from your bones, which can weaken them over time.
Safety profile
Data not available for this specific product's side effects. However, 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]. The FDA has received a total of 592,059 adverse event reports for calcium supplements overall [FDA data]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Do not start this supplement without first discussing it with your doctor. Given the potential for heart disease risk and serious medication interactions, you need a professional assessment of your personal calcium needs, ideally based on a blood test [NIH ODS]. If you are already taking any of the listed medications, this product could make them less effective, so proceed with caution [NIH ODS].
