Spirulina is a wonderful superfood packed full of nutrients. It’s a cyanobacterium, (blue green algae), and is a complete protein containing all essential amino acids.  As a protein, it doesn’t actually compete with meat or eggs as an example but it is, however, superior to typical plant protein such as that from legumes.  This makes it a great protein option for vegetarians or vegans.
Spirulina is an excellent source of many nutrients; particularly B Vitamins thiamin and riboflavin, and also dietary minerals such as iron and manganese.
It doesn’t exactly have the best taste unfortunately, I would love to find someone who has tasted Spirulina and doesn’t reference it to what must only be pond scum, but nevertheless it is very good for you.
So I drink it, whilst trying to mask the taste as much as possible.
I blended this really simple smoothie with banana, spinach, avocado and ice with one tablespoon Spirulina.
