Our assessment
The evidence shows that the primary active ingredient in Pure Encapsulations Collagen JS is likely calcium, based on the data provided. Our assessment is that this product may support bone health, but you must be cautious about your total calcium intake from all sources, as high levels carry significant risks [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone density and mineral deposition, which is essential for maintaining strong bones. Additionally, it plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports for products in this category. Data not available for report counts specific to this product. You should be aware that some research suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to assess your total daily calcium intake from food and all supplements before adding this product. If you take any of the listed medications, separate your calcium dose by at least 2 hours. Do not exceed the tolerable upper intake level without medical supervision. If you have a history of kidney disease, heart problems, or prostate cancer, consult your physician before use [NIH ODS].
