Spirulina smoothie

I've been given a few different health supplements for Christmas, one of which is spirulina powder. I'll be adding it to my breakfast smoothies for the next couple of weeks to see if it has any effect. Just had one now and it's certainly an acquired taste, but as with all these things it's just a question of getting used to it.

I'll be mainly using an orange, carrot, tomato and cucumber base. Perhaps with any left over grapes I can find.
