The catch

It is expensive at about 2.33 dollars per serving for only 20g of protein, and it does contain a small amount of added coconut palm sugar. (source)

The honest take

This is a USDA organic plant protein that blends brown rice, pea, and hemp for 20g of protein per scoop, then layers in functional mushrooms (lion's mane, reishi, turkey tail), a greens blend, and a probiotic. Sugar stays low at 2g per serving, sweetened with a little organic coconut palm sugar plus monk fruit rather than sucralose or stevia, which will appeal to anyone avoiding artificial sweeteners. The real question is value, since a tub runs about 35 dollars for 15 servings, or roughly 2.33 dollars a scoop, which is steep next to plain pea or whey. You are paying a premium for the organic sourcing and the mushroom and greens extras, so it makes sense only if those are things you actually want.

Who it's for

✓ Buy it if

Plant based shoppers who want an organic, low sugar protein with functional mushrooms and greens built in and do not mind paying for it.

✕ Skip it if

You just want the cheapest gram of protein, since a plain pea or whey isolate delivers far more protein per dollar.
