I use it every day, it taste’s ok when I mix it with Orange juice. I run six days a week and ride six days a week, doing roughly 700-800 TSS per week. Monday is a run only day; and Tuesday is a ride only (VO2) day - so doing something every day, and two workouts a day on 5 days.
I am building run volume which is why I started the Collagen; based on the podcast. How do you know if it works or not - that is the big question.
I have gone from not running at all in November, to now running 4 hrs per week. No injuries so far and I don’t have sore joints. I have had joint pain before and have struggled to integrate running into my plan before - this time no issues; I would be a little hesitant to give all the credit to Collagen though
