                                While liquid collagen is widely promoted for its beauty and wellness benefits, a 2021 study indicated that even high doses of hydrolyzed protein were not likely to cause significant issues for most users. However, this general safety profile does not mean that adverse reactions are non-existent, particularly for individuals with pre-existing conditions or allergies. The potential for mild gastrointestinal discomfort or allergic responses makes understanding the possible side effects crucial before starting a supplement regimen.
