I'm probably not of the majority opinion but I tend to think Fortibone is a bit of hype. The name is quite suggestive and the only research on collagen peptides/Fortibone was done by Gelita, the company that manufactures this product. I can't imagine it is any different from other collagen peptides other than branding. I use Vital Proteins which is good quality, marine or bovine sourced from grass-fed cattle. Something to be aware of with collagen is that it is not a complete amino acid profile, lacking tryptophan, so it can be anxiety producing.
