ioPea Protein: A Plant Protein With the Power of Whey

The masterminds behind Ingredient Optimized Technology.

Vegans and vegetarians mainly get protein from legumes, whole grains, nuts, and seeds. But since vegans and vegetarians consume anywhere from zero to a minimal amount of animal products, it can be extremely difficult for that population to intake enough high-quality protein. Therefore, many of them rely on plant-based protein powders.

Over the past few years, the popularity of vegan protein powders has been on the rise, especially in sports nutrition. But there are some potential issues with plant protein products that you should be aware of.

The Potential Downfalls of Plant Protein

Since plants grow in the ground, they’re at risk of containing excessive amounts of heavy metal. This is an issue for everyone, not just vegans and vegetarians. But, it’s more of a concern for vegans and vegetarians because a larger portion of their diets is comprised of plants. So companies should be careful where they source their plant-protein from.

And also really important is the fact that the majority of plant proteins are classified as incomplete proteins because they lack an adequate amount of one or more of the nine essential amino acids. Essential amino acids (EAAs) must be supplied by the diet and/or supplementation because they cannot be produced by the body.

Out of the 20 amino acids in existence, nine are considered essential. They include:

  • Leucine
  • Isoleucine
  • Valine
  • Histidine
  • Methionine
  • Phenylalanine
  • Tryptophan
  • Lysine
  • Threonine

Three of the nine essential amino acids — leucine, isoleucine, and valine — are classified as branched-chain amino acids (BCAAs) based on their unique structure. The three BCAAs, especially leucine, play an important role in muscle protein synthesis (the generation of proteins in the body). So if you’re looking to maximize your performance, recovery, and health, it’s vital to consume enough protein that’s rich in EAAs and BCAAs.

Unfortunately, the majority of plants lack sufficient amounts of EAAs and BCAAs, especially leucine, which is the main trigger of muscle protein synthesis (MPS). To solve this problem, manufacturers combine various complimentary plant protein sources. For example, it’s common to see a brown rice protein and pea protein blend in vegan protein powders because the amino acids lacking in brown rice protein are in rich supply in pea protein.

This isn’t a problem with animal-based protein powders because they’re complete protein sources, such as whey or casein. In fact, whey protein is considered the gold standard for protein powder because of its impeccable amino acid profile and bioavailability. Several studies have shown that whey protein increases plasma levels of amino acids significantly more than nearly every other protein source, especially plant proteins.[1-3]

If only there was a way to make plant proteins with the power of whey…

Introducing Ingredient Optimized Technology and ioPea

Up until this point, plant proteins have been considered inferior to whey, but thanks to the masterminds behind Ingredient Optimized Technology that’s quickly changing. Ingredient Optimized (io) is an innovative company in the sports nutrition industry that has spent years developing, researching, and testing ways to make a plant protein that performs as well as whey protein.

After years of development, io has finally done it with ioPea protein, the first ingredient in their ioPlant series. ioPea protein is a naturally-optimized plant protein. It’s actually been shown, in two human clinical trials, to be just as good as whey protein and better than standard pea protein.[4]

Plantein from Kaged Muscle was the first product to use ioPea.

Some key features of ioPea include:

  • Nearly 3x more bioavailable than standard pea protein, according to studies
  • Tastes neutral
  • No third-party ingredients added
  • Easy to use in foods, supplements, and beverages
  • Clinically backed with over five years of research and development
  • Safe and compliant technology that maintains GRAS (generally recognized as safe) status
  • Available as USDA Certified Organic, NSF Certified for Sport, Halal, Kosher, NSF (GMP Certificate), and SQF Level 2[5]

ioPea hasn’t been around for very long, but it’s already gaining traction in sports nutrition. For example, Kaged Muscle, a well-respected supplement brand, was the first company to use ioPea protein — in a product called Plantein, which came out in September 2020. Approximately a month after, another popular brand called Performix designated ioPea as the primary ingredient in ioPlant Protein. Both brands were seeking to innovate vegan protein powders and thanks to ioPea, they were able to do that.

Ingredient Optimized Technology: A Natural and Clean Label Process

Ingredient Optimized Technology uses a natural atmospheric plasma treatment process to enhance the surface area, solubility, and dispersibility of protein molecules (i.e. whey or pea protein).[4,5] Unlike other processing methods, io doesn’t use any harmful chemicals or enzymes to alter the structure of the protein.

Instead, Ingredient Optimized Technology carefully changes the tertiary and quaternary structure to expose the hydrophobic pockets of the protein molecules.[4,5] This allows for enhanced absorption and bioavailability, as well as reduced stomach discomfort.[5]

Before using Ingredient Optimized Technology with pea protein, io began researching and testing this technology with whey protein nearly five years ago. After several human clinical trials, io discovered that whey protein treated with the Ingredient Optimized Technology was superior to standard whey in terms of enhanced bioavailability for essential amino acids, particularly leucine.[6,7]

Ingredient Optimized even found that compared to standard whey protein, you can use up to 35% less ioWhey and still get a similar amino acid delivery.[6] Furthermore, subjects that consumed the lesser amount of ioWhey experienced similar strength and muscle mass gains as a higher dose standard whey protein.[6]

After discovering their technology has such a profound effect on whey protein, io turned their attention to plant proteins — specifically pea protein.

Pea protein is actually one of the few plants that are classified as a complete protein. In fact, one randomized controlled trial from the Journal of the International Society of Sports Nutrition found that pea protein isolate performs just as well as whey for increasing muscle mass.[8]

However, pea protein’s leucine content and bioavailability still don’t come close to whey or casein, and some would argue that pea protein is technically not complete because although it contains all nine EAAs, it’s rather low in methionine. Fortunately, by applying Ingredient Optimized Technology to standard pea protein, io is able to overcome all of the downfalls of pea protein. Somehow, they were even able to create a pea protein with an amino-acid profile as comprehensive as whey.

ioPea Protein vs Hydrolyzed Whey

In two double-blind, randomized, crossover trials, researchers from the Applied Science and Performance Institute compared the postprandial plasma essential amino acid (EAA) and branched-chain amino acid (BCAA) responses from various protein sources in 10 resistance-trained men.[4]

The five main comparisons of the study were:

  1. Hydrolyzed whey protein isolate (HWPI) vs. plasma modified non-hydrolyzed whey protein isolate (PM-NHWPI)
  2. Standard branch-chained amino acids (S-BCAA) vs. plasma-treated branch-chained amino acids (PM-BCAA)
  3. Standard pea protein (S-PP) vs. plasma modified pea protein (PM-PP)
  4. Hydrolyzed whey protein isolate (HWPI) vs. plasma modified pea protein (PM-PP)
  5. Standard leucine (S-Leucine) vs plasma modified leucine (PM-Leucine)[4]

Since we’re focusing on ioPea (plasma modified pea protein) in this article, we’re only going to discuss the third and fourth group comparisons.

For the S-PP vs. PM-PP comparison, participants were instructed to consume 25 grams of powder of S-PP or PM-PP after an overnight fast. The same conditions were used for the HWPI vs PM-PP comparison.[4]

The two conditions were separated by a seven day washout period. Researchers measured the participants’ branch-chained amino acid and essential amino acid plasma concentrations via blood samples at 30, 60, 90, 120, and 180 minutes after ingestion.[4]

The results showed that the PM-PP had a greater bioavailability of leucine, BCAAs, and EAAs, and was up to three times more bioavailable overall compared to S-PP.[4] Furthermore, the PM-PP and HWPI had no significant differences in their ability to elevate plasma levels of BCAAs and EAAs.[4] This means that PM-PP, also known as ioPea, is an adequate alternative to HWPI.
