PureFormulas Calcium Citrate
Brand: PureFormulas · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is essential for bone health and muscle function, but you need to be precise with your dosage. Our assessment is that PureFormulas Calcium Citrate can be a reliable way to meet your calcium needs, provided you are aware of the specific risks and interactions tied to high intake [NIH ODS].
How it works
Think of calcium as the primary building block for your skeleton. It supports bone mineralization by depositing into your bone matrix, and it also facilitates neuromuscular relaxation by helping your nerves signal and your muscles relax after contraction [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though specific report counts for this product are not available. You should be cautious: high calcium intakes might increase the risk of heart disease and prostate cancer. High levels in your blood or urine can cause 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] [FDA data].
Our recommendation
Start by checking your total daily calcium intake from food and other supplements. Calcium can reduce absorption of bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin — so take this supplement at least two hours apart from those medications [NIH ODS]. Stick to the dosage on the label and do not exceed the Tolerable Upper Intake Level without your doctor’s guidance.
