Protein Crunch Bar Ingredients

Only 5 Grams Sugar

Fun fact: Adding a little sugar to protein helps your body absorb the protein better, making it more effective.* And five grams of the sweet stuff is just enough to make Signature Protein Crunch Bars taste like a treat without derailing your clean diet.

Whey Protein

This snack is packed with 20 grams of whey protein to fuel muscle growth and fight muscle breakdown. Protein also helps you feel fuller longer than carbohydrates or fat can.*


The 5 grams of fiber in this bar help you feel fuller with fewer calories. Fiber takes its time moving through your digestive system, keeping you satisfied longer and supporting digestive health.* Signature Logo

A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, was founded on a single promise: Trust. It’s who we are and it’s in our blood. Our Signature line is built on the same promise. Every product is no-BS, transparent, filler-free, and formulated with effective doses of research-backed ingredients you can trust. We create the highest quality supplements, so you can focus on leaving a mark of your own.

Total Transparency

Signature products are formulated with high quality ingredients at effective doses that we’re proud to share with you. We don’t hide anything in a “proprietary blend,” so you always know exactly what you’re putting into your body.

Effective Doses

An effective dose is the amount of an ingredient that has been shown to deliver results. Some supplement brands add a sprinkle of an ingredient just so they can say it’s in the product. Signature supplements always include enough to get the job done.

Research-Backed Ingredients

Trendy, flash-in-the-pan ingredients come and go. But time-tested, gym-proven ingredients are what you need to help you achieve your fitness goals. That’s what you’ll find in Signature products because that’s what works.

  • 10 Chocolate Peanut Butter
  • 8 Cookies and Cream

Cookies and Cream taste similar to the Double Chocolate Chunk if you ever had it and it's good, but Chocolate Peanut Butter is by far the best flavor in my opinion

Bring back the Double Chocolate! It was the best flavor by far. The others taste good, just not as good. Better than the cardboard you get from most other companies. Bit too sweet but it's a candy bar essentially so it's what you'd expect. If the double chocolate wasn't discontinued I'd give the flavor a 10/10 and buy a box a week.

Got a free sample of the double chocolate chunk in my amino acid drink. Loved it. Now they don’t have that flavor as I was going to order for the first time. Was trying to decide between cookies n cream or choc chip cookie dough until I read the review about the gas issues. Now nervous. Anybody else have these issues?

What happened to the Double Chocolate Chunk?! Those satisfied my sweet tooth perfectly! Trying the Cookies N' Cream now but sad to see the double chocolates discontinued.

My wife and I really like these bars. Great flavor and a nice snack before or after a workout. They can be a little tough to chew, so be aware. The calories are a little high, so we usually split one. Overall, we are pleased!

This came in a box of one of my orders as a bonus. Tried it, surprisingly pretty good. I would buy it, if it was cheaper though. The only downside I can say is it gets stuck in your teeth very easy. Overall, not bad.

Too sweet,I don't know how 5 grams pf sugar could make a product so sweet. I threw away the Cinnamon roll flavoured ones. They were disgusting.

Chocolate chip cookie dough—delicious. Cookies and cream—delicious. However, the rocket fuel gas this product gave me was highly undesirable. It sounded like all the zoo animals were in my britches. At first I thought that it might have been something else that I ate until it happened again. Performance in the bedroom was hindered due to the overpowering flatulence on VALENTINES DAY of all days. Overall pretty good product if you can deal with the feeling like you can fly to the moon and you don’t like to get laid.
