I had my first Mana order during the summer and reeeeeally wanted to like it but I kept getting a bad stomachache, headache and general sickness afterwards. I had one bad allergy incident once and broke out in hives. I later compared my reactions of this to vegan protein drinks that I have had in the past and was able to narrow down the culprit to pea protein.
That being said, as I had discovered my intolerance to pea protein, I saw that there is now increasing awareness of pea protein intolerance as more pea protein is used in the market. Clinics have also found some people with peanut allergies to have a cross-reaction with pea protein. So I just wanted to suggest the idea of removing pea protein or making a line of Mana without pea protein (maybe even substitute with whey or something else), as there are only a few companies now that make drinks without pea protein.
Unfortunately, I had to switch to a different company of drinks due to the intolerance, but I would love to switch back to Mana because of the nutritional profiles and company ideology.
