Collagen peptides are generally well-tolerated and have no widely documented drug interactions. However, if you take blood thinners or antibiotics, consult your doctor before starting any new supplement. The hydrolyzed bovine collagen in this product is a food-grade protein, not a pharmacological compound.

Most users tolerate this product well, as reflected by its 4.4-star rating across over 212,000 Amazon reviews. Some people may experience mild bloating or a feeling of fullness when first starting collagen, especially at the full 20g dose. Starting with one scoop and gradually increasing can help minimize any digestive adjustment.
