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.

Don't think it's really lactose-free as purported....disappointing

I decide to try this protein, mainly because the price and also because I thought that the brand will guarantee the product quality. Nevertheless, my experience has been negative. The protein is not easy to digest and after consuming it, I don´t feel the punch I feel with other whey isolates. In my case, next time I will spend some more with a different brand.

We love this protein!! I add it to plain Greek yogurt, drink it mixed with water, or heavily blend with ice and almond milk for a sweet dessert!!! Love the frothy texture.

The consistency of the shake and the flavor itself is delicious as all can get. No issues there. However I had to go elbow deep to the very bottom of the container to get the scoop, hopefully that doesnt happen to you

Really love this whey isolate! Chocolate taste is super good as I am a chocoholic. Vanilla is decent. Love that this product is both gluten and soy free in which most whey isolates include soy.

Bagged this at a BOGO offer and for the price I got almost 150 servings for the price at one. I can't complain. I find the chocolate a tad salty with water but it tastes great when mixed with Milk or almond milk. Mixes well and there is no grit or clumps. I prefer the vanilla flavour.

Mixes well, with a great taste. Doesn't leave a weird after taste like some others. Some proteins bloat me bad or have me clearing out rooms all day, but this one sits well. Dymatize iso100 is the only other one that sits well I've found. I'll be ordering this until I get tired of it, then I'll try vanilla. Hopefully by then they have more isolate flavors.
