I don't know. I take a bit less of a lot more stuff. I eat good whole cranberry cranbeary sause for 88 cents a can, eat canned blue berries, take vitamin C with bioflavonoids, multi-vitamin, 2mg biotin, 2-3g of fish oil, ... well, I'm not going to list my whole regimen, but I get it cheap and I take it throughout the day, not all at once. My joints are starting to feel a lot better. I can put a lot of weight on the leg extensions, whereas before my knees hurt if I did more than 20 pounds. That was a long time ago, though, and I've been building them up. Soon I'll cut up some garlic and mix it with my food each day.
And cocoa powder is cheap and loaded with good stuff. I get the unsweatened stuff. Tastes good to me.
