Hi Pebbles
My coach also told me it could be a freebie every-other day or a sub for a regular packet every other day.
IP-wise, besides the blue cran & jelly there are a couple other sources of collagen: Strawberry Banana RTD and chicken noodle soup. I believe the last two have both kinds of protein so they ARE complete proteins.
The reason some are limited is because the collagen (or gelatin) is not a complete protein. There are NUMEROUS choices from Nashua. Any of the ones that gelatin is the primary source of protein would fall into that category. Here are some examples:
Proti Thin Liquid Concentrate Drinks & Chicken Noodle Soup
Proti Diet Liquid Concentrate Drinks & Chicken Noodle Soup
Health Smart: Cran Grape, Grape, Grapefruit drinks & chicken bouillon.
I'm sure there are others but these are the ones I found doing a quick glance.
