Product Overview

Bodybuilding.com Signature 100% Whey Protein Isolate

Whey protein isolate is protein at its best. It has been filtered to remove the majority of the lactose, fat and carbs, making it higher in protein, leaner, and faster digesting than standard whey protein. Its quick release of amino acids is ideal for supporting post-workout muscle growth and recovery.* Signature Isolate is delicious and fits any clean-eating plan with 110 calories, 0g of sugar, 0g of lactose, and 1g of total carbohydrate.

WHEY BLEND BREAKDOWN

Bodybuilding.com Signature Whey Blend Breakdown Chart

HYDROLYZED WHEY PROTEIN ISOLATE

Over half of the protein in Signature 100% Whey Protein Isolate is hydrolyzed. The peptides from hydrolyzed proteins are much easier for your body to digest than standard long-chain proteins or free amino acids. That means better absorption of these muscle-building aminos.*

But amino acids that come in the form of a peptide — in other words, already broken down through the hydrolyzation process — bypass all that and can be absorbed intact. Once they’re absorbed, the body breaks them down further and releases a flood of amino acids. Research shows that hydrolyzed proteins are absorbed more efficiently than straight amino acids. In fact, scientists estimate that two-thirds of amino acid absorption occurs in the form of small peptides, with only one-third absorbed from free amino acids.

WHEY PROTEIN ISOLATE

Why isn’t all the protein in this product hydrolyzed? It all came down to taste: Peptides are bitter! We pushed the envelope to provide as hydrolyzed whey protein isolate as possible, but the bottom line is that protein won’t work if you can’t bear to drink it.

A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, Bodybuilding.com 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.

Thank you Bodybuilding.com for developing such a great protein powder. Absolute best tasting protein powder I ever had next to the original Pro Jym before they changed. Pro Jym is now disgusting which forced me to try a new protein powder and I am so happy that I did find the best which is the Signature Series line.

I wanted to use this product continuously before writing a review. Ive been using it for about 2 weeks now and all I can say is WOW! The low carb/fat is ideal for when you’re in the process of shredding down and yet the flavor satisfies those cravings and hunger. I look forward to seeing more flavors of the isolate!
