Puritan's Pride High Potency Calcium 600
Brand: Puritan's Pride · Form: TABLET [E0155] On Market
Our assessment
Our assessment: Calcium is a foundational mineral for bone health, but the evidence shows that supplementing with 600 mg per dose requires careful timing and awareness of your total daily intake. For most adults, the RDA is 1,000 to 1,200 mg from all sources, so this product can help you meet that target, but you must account for calcium from food [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. This means adequate calcium helps your muscles relax properly after contracting and helps your nerves send signals efficiently.
Safety profile
The FDA has received a total of 592,059 adverse event reports for calcium supplements. Data not available for the specific number of reports for this exact product. The NIH ODS notes that very high calcium intakes may increase the risk of heart disease and prostate cancer. High levels 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].
Our recommendation
Do not exceed 2,000 mg of total daily calcium from food and supplements. Take this tablet with a full glass of water and at a different time than medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin to avoid absorption issues [NIH ODS]. Start with one tablet daily and assess your dietary calcium intake first.
