076: How much vitamin C should I take with collagen?

Masterjohn Q&A Files Episode 76


There's no evidence that you need to take vitamin C with collagen. There is a study by Keith Baar, who showed that 15 grams of gelatin, not collagen, but I suspect the collagen is exactly the same, 15 grams of gelatin but not 5 grams, the dose is important, with 50 milligrams of vitamin C taken before exercise improved collagen synthesis in the tendons. They included 50 milligrams of vitamin C because it's made for collagen synthesis, but they don't show that you needed the vitamin C. They just had the vitamin C in there. I don't know if it even matters in that context whether you need the vitamin C. I also have no reason to think that you need 50 milligrams instead of 10 or that 100 milligrams wouldn't work better because they didn't test the different doses. They tested the different doses of gelatin. I see no reason to think a high dose of collagen is any different in this respect.
