I've taken glucosamine and chondroitin for many years now, but for arthritis. Doesn't do jack for an excessive workout, though. Take some ibuprofen to help lessen the inflammation in your legs, massage and ice them, too. Trust on this.
I don't feel like I need any nutritional supplements honestly with how varied and healthy my diet is.. That just makes me think how one of my biggest pet peeves is the vitamin industry as a whole. People eat a crap diet and take a pill form of the vitamins they could be getting in their food for some reason. God bless America
