@sabrina2 I mix Vega plant based protein powder in my cilantro shake. It is unsweetened and has no flavor. It comes in flavors but they usually are sweetened. I do not like the fake sugar substitutes. Grains and legumes are not allowed on the whole 30 diet. That diet changed my digestive issues from pain when having a bowel movement to being normal, absolutely heavenly, daily normal. The cilantro is big aid in digestion also. You can check out the ingredients in Vega at a Whole Foods or online to see if you are allergic to any ingredients. Will try to post a photo of it.
