Just one product may not be enough in the long run. For any product there are at least a few varieties always available. For example for frozen meals there are so many different kinds of meals from the same company: shrimp, chicken, beef, vegetable etc.
I’m just guessing: The presence of enzymes has no disadvantage for any significant portion of the population but if it does, sure there should be a variety without them. I haven’t seen anyone saying “It needs some sugar”. Its always about less sugar so at the least they need to reduce it down further. Probably bring it down to 10 or 15mg from 30. They already recommend people adding peanut butter to it if needed. Sugar should be an added additive, not something that can be detected by most people. The aftertaste of this sugar is something I have seen multiple people complain about. Yea we know they added some to improve the taste but at this time too many people including me do not like the sweet taste and its aftertaste. I had it 3 hours ago and it still lingers in my mouth and I feel its pretty unpleasant. If masking bad taste is the aim, maybe something else needs to be added or the sugar further reduced.
Salt could be the daily nutrition level. I think (?) some people calculated the amounts of sodium in the beginning and said it was not enough.
Protein - just normal daily recommended quantity. Anything more should be an additive for a small portion of customers that need it: athletes).
Oil - Vegan and non-vegan could be two different varieties depending on if there’s a significant percentage of customers who need it so thats good.
I see multiple varieties happening eventually but I feel at this point they will be very resistant to do that (understandable as they are trying to evolve the one kind they have started out with).
So for that one kind I’d definitely reduce the sugar first, watch further feedback and continue to improve the gas problem.
Different sources of protein sounds like a good idea.
