do collagen supplements work

Is collagen used as energy?
Heard lots of benefits for supplementing with collagen, include tissue repair, cartilage health etc. So does the ingested collagen goes straight through the system to does all the ‘work’ or rather be used as energy?
Collagen made the fad diet circuit a few years ago,, Collagen isn’t an energy supplement, It may or may not help the body by promoting the bodies metabolism to burn fat,,
I used it along with glucosamine and chondroitin to help my aching knee joints 7-8 years ago,,
MVHO is, there isn’t any value in spending money on those supplements,,
I also sucked down real ephedra based diet products,, Now those actually did help burn fat and provide a false sense of an energy boost,, but they could be dangerous to your health since they cause your blood pressure to rise ,,,
Getting yourself onto a health diet and exercise program will do the same thing and it’ll both save you money, and be more effective in the long run,,,
Good luck,,,
