Our assessment
The evidence shows that Irwin Naturals Collagen-Pure contains calcium, a mineral essential for bone health. Our assessment is that while this product may support your skeletal system, the calcium content requires careful consideration of your total daily intake from all sources [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. If you are already getting calcium from your diet, adding a supplement like this could push your intake to high levels.
Safety profile

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 across all supplements, but specific report counts for this product's side effects are not available [FDA data].
Our recommendation
Start by calculating your daily calcium intake from food sources before adding this supplement. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Our recommendation is to consult your healthcare provider to determine if this product is appropriate for your individual needs and to avoid exceeding the tolerable upper intake level for calcium [NIH ODS].
