Good collagen?

Hello. I’ve been following this friend who is doing very with Isagenix. She looks amazing for her age and says it’s all thanks to Isagenix. I see the packages that are built for customers and holy moly, they are in the hundreds range! I am in my mid 40’s and would love a good collagen and anything else that is tried and true for you. I’m super hesitant to subscribing to an MLM. And I don’t want to be tied to anything. As a female in her mid 40’s, I just want a handful of good high quality supplements you recommend. Thank you.
