Summary

MET-Rx Big 100 Bar scores 35/100. The lowest-scoring protein bar in the rankings. Despite 30g protein and 17 added vitamins/minerals, the ingredient list is a disaster: soy protein isolate as the primary protein, corn syrup, sugar, maltitol syrup, fractionated palm kernel oil, fructose, canola oil, and natural flavor. The vitamin fortification is a smokescreen for what is essentially a candy bar with a supplement label. 100g bar size means you are consuming massive amounts of these harmful ingredients.
