Our assessment: you can use this product as a protein source, but its specific health benefits beyond basic nutrition are not supported by the data provided here.
How it works

Safety profile
The FDA has received a total of 592,059 adverse event reports across all dietary supplements, though specific reports for this product are not available in the data provided [FDA data].

Our recommendation
If you choose to use Bulletproof Collagen Protein Unflavored, be aware of the calcium content and its potential interactions with medications.
