CLIF BUILDERS Protein Bar review

CLIF BUILDERS is the cheapest way on this list to get 20 grams of protein in a bar. A 12-bar box of Chocolatey Peanut Butter costs $22.90 on clifbar.com, about $1.91 a bar, and subscriptions take 15% off. The protein is plant based, led by soy protein isolate, and CLIF says the bars are gluten free, Non-GMO Project Verified and low glycemic, with no high-fructose corn syrup and no artificial sweeteners. That last point is the trade-off: instead of maltitol or sucralose, BUILDERS uses organic cane syrup, cane sugar and brown rice syrup, which sit right after the protein in the ingredient list, so it is not the bar for sugar counters. CLIF also sells BUILDERS High Fiber, reduced-sugar Crispy bars and Minis at 10 bars for $11.64. Buyers who want artificial-sweetener-free plant protein for less than $2 a bar will find nothing cheaper here.
