Bulletproof Collagen Protein Unflavored
Brand: Bulletproof · Form: POWDER [E0162] On Market
Our assessment
The evidence shows that Bulletproof Collagen Protein Unflavored contains calcium, a mineral that plays a role in bone health. Our assessment: while collagen proteins are popular for joint and skin support, the calcium content here is the primary data point we can evaluate. The specific amount of calcium per serving is not listed in the provided data, so we cannot calculate your exact intake from this product [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 using this product as a protein supplement, the calcium it contains contributes to your daily mineral needs, but its primary function in this context is supporting overall mineral balance.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. 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. Because of this, we cannot recommend this product as a reliable source of calcium. If you are taking medications like thyroid hormone or antibiotics, be aware that calcium can interfere with their absorption. For general bone health, we recommend meeting your calcium needs through food sources or a standardized supplement with a known dosage. Consult your healthcare provider before adding this product to your routine, especially if you have a history of kidney stones or heart conditions [NIH ODS].
