You're probably right... but since Fortibone-based collagens are the only ones studied and found effective, then that is what I use. Maybe someone will do more research.

I would challenge this thought process although it is understandable. Marketing opportunities can easily manipulate us. However, my last dexi resulted in increased bone and the only thing that I did differently was consistent collagen with Fortibone. Although I have a long way to go, I feel stronger and less frail and as I study more, Fortibone reduces fragility fracture %. Granted, I am only one person but for me, there seems to be improvement. I am not willing to take collagen without fortibone.

@normahorn - YES! Marketing. There is so much deceitfulness in it. I am affiliated with a wellness manufacturer and boy have I heard the stories in 33 years. We have a very truth focused research and development team - money never rules.

I am so skeptical to purchase or recommend purchasing any supplement off a store shelf these days - and even health food stores.
