Our assessment
Our assessment: Pure Encapsulations Collagen JS contains calcium, and the evidence on calcium is clear. Data not available for other ingredients in this specific product. Calcium supports bone health, but the risks of excessive intake are significant and require your attention [NIH ODS].
How it works
Think of calcium as a structural builder — it supports bone mineralization and density, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS]. This makes it essential for your skeleton and muscle function.
Safety profile
FDA received 592,059 total adverse event reports for this supplement category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects of high calcium levels include 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]. Calcium can also reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Check your total calcium intake from all sources — food and supplements — to avoid exceeding safe levels. If you take medications like thyroid hormone or certain antibiotics, separate your calcium dose by at least 2 hours. Data not available for other ingredients in this product, so consult your pharmacist before starting [NIH ODS].
