Mana is everything I wanted Soylent to be. I've tried a few different meal replacements, and Mana is the best by a mile. The RTD shakes had a bit of a chemically note to me which was disappointing, but they were super smooth and still tasted good and did away with my hunger. What I'm really blown away by is the powder, particularly Origin. It is truly neutral and delicious. It's smooth, filling, not overly sweetened, and it doesn't sit heavily on my sensitive stomach. I work a physical job in hot temperatures with long hours, so Mana is a godsend for lunch, since it takes no time at all, and is yummy, filling, and refreshing.
