Our assessment
The evidence shows that Bulletproof Collagen Protein Unflavored contains calcium as an ingredient. Our assessment is that while calcium is essential for health, the specific amount per serving in this product is not provided in the data, so we cannot evaluate whether this supplement provides a meaningful or excessive dose. Data for the collagen protein itself is not available from the provided sources.
How it works
Calcium supports bone mineralization, helping to maintain bone density and mineral deposition. It also plays a role in neuromuscular relaxation, supporting proper muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA has received 592,059 total adverse event reports across all supplements. For calcium specifically, some research suggests high 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
Data not available on the exact calcium content per serving in Bulletproof Collagen Protein Unflavored, so we cannot recommend a specific dosage. If you take this product, be mindful of your total calcium intake from all sources and supplements to avoid exceeding safe levels. Consult your healthcare provider before adding this to your routine, especially if you take any of the medications listed above [NIH ODS].
