Consumer advice
The product itself is fine as a protein/collagen supplement, but ignore the Q&A anecdote claiming collagen made hair grow 4x faster - that's not biologically plausible and isn't supported by any research. If your son is losing hair, see a dermatologist; minoxidil (mentioned by another reviewer) actually has clinical evidence for hair regrowth, unlike collagen. Check the Prop 65 question thread too - there have been heavy metal (lead/cadmium) contamination concerns raised by reviewers and the brand's own inconsistent answers on this are a bit concerning. Compare price per serving against other collagen brands before buying, since collagen peptides are largely a commodity ingredient.
