I love the proliferation of the squeezable form factor for foods. But most of them are aimed at toddlers in their flavor profiles and nutrition. This, however, is for grownups. It is made of chia seeds and fruit/vegetable juice. It has a great mix of fiber, fat, and protein for labor sustenance in a form factor that is easy to sip a little at a time.
It is a learn-to-love it texture for some, so try it out ahead of labor so there are no surprises if you're not familiar with chia.
