feed suggestions for adding sparkle to dressage horse

My 16 yo average doer really needs more oomph for competition. He's fit and healthy but lazy by nature and competing ele/medium. He's currently on alfa A , feed balancer and top line cubes. Any suggestions?

Equijewel on top of your current feed would work well!
Or linseed!
