I feel that if you feed a good pellet and fresh veggies,fruits there is no need for supplements. The only time I would use a supplement is for female parrots and it would be calcium if egg shell wasn't used in birdie bread or like cooked foods. Again JMO There is a good book called "The Healthy Bird Cookbook" by Robin Deutsch that has Species Specific recipes to make sure your parrot gets a well rounded diet.
