I mixed this up in my car on my morning drive and it was super easy. It dissolved well with no clumps or mess. The watermelon flavor is very muted, which means it's not overpowering or sickly sweet, but I do wish it had more punch. The color was also a bit off-putting, though it didn't affect the taste.
That said, with 20g of protein, 3g of fiber, and zero sugar, it definitely serves its purpose for this GLP-1 diabetic girl. When I need protein without the sugar spike, this gets the job done.
Would I buy it again? Yes, for the nutrition and convenience. I'd just love a bolder flavor.
