OK, so I have 4 big questions (maybe more) but these 4 come to mind after reading all blog post and (kid you not) nearly all comments on those posts.
There was a concern about some nutrients inhibiting the absorption of others, namely calcium and iron (and specifically when they’re in the small intestine together). No one ever addressed this further. I’ve read several studies about this and it seems to be the case. Has anyone studied what other conflicts there may be? And if this is the case, wouldn’t we need multiple shakes throughout the day, each with nutrients that didn’t inhibit each others’ absorption?
It’s well established that a lot of nutrients are more easily absorbed by the body from food rather than supplements. To further complicate things some nutrients absorb better when taken with food while some absorb better when taken on an empty stomach. I would like to see some lab work from Rob or others taking the trial for the presence and level of these nutrients. It just seems like too many variable to shake everything up in a single batch and call it a day. The calculations are loosely based on RDA’S, but how can anyone be sure that actual absorption is anywhere near what’s recommended?
I’ve seen a few recipes here that rely heavily on “Now Foods” as a supplier, however they just had a recent callback for their softgels where vitamin d was 5000 times the stated level. Point being, we can never fully trust what any supplement provider tells us in in their products. Imagine if that had been potassium instead of vitamin D. This is less of a question and more of a statement to be careful.
I’m rather concerned that maltodrextin in such high quantities (eg 250g - 400g) on a daily basis could promote diabetes. Is everyone settling on this as a carbs source? What are the alternatives?
