This works..

/give @p minecraft:potion 64 16385 {CustomPotionEffects: [

{Id:23, Amplifier:3, Duration:1000000}

], display: {Name: "Sports drink"}}

but this doesn't..

/give @p[team=blue] minecraft:potion 64 16385 {CustomPotionEffects: [

{Id:"minecraft:saturation", Amplifier:3, Duration:1000000}

], display: {Name: "Sports drink"}}

You can see all available effect names when pressing "/effect @p <TAB>".
