My preference is Holfood (Chocolate). Canadian company, produced in Toronto. It has a nice flavour and isn’t too filling.

Compared to other nutrition shakes I’ve tried in the past:

• Soylent powder and Holfood Vanilla are both very similar and taste very artificial. It’s not what I would call “bland”.
• Boost and Ensure: They’re always way too sweet (I would not be able to consume more than maybe 300 Calories worth in a day), and much more expensive than the alternatives when you consider the nutritional value.
