4 Reasons Your Body Needs Hydrolyzed Protein

When protein hydrolysatesoften called hydrolyzed proteinsfirst hit the shelf in the early 2000s, not much was known about their impact on size and performance; we just knew they digested faster than traditional protein powders. Some people wondered if that actually made a difference, and labeled hydrolysates a gimmick. Now we know better.

A decade later, we now have more research to pull from, and both whey and casein hydrolysates are making a comeback. Will they ever be as popular as isolates or concentrates? Perhaps not, but beyond lightning-fast digestion, whey and casein hydrolysate offer serious advantages in certain situations. Here's what you need to know!

Hydro-What?

A protein hydrolysate refers to a protein that has been partially digested or "hydrolyzed." Don't worry, it's not as if someone began chewing your protein and spat it back out. This process involves adding proteolytic enzymes, which break down protein, or heating a protein with acid. Both mimic the digestion process and result in intact proteins breaking down into single amino acids and small amino-acid peptide strands.

Hydrolysis potentially fuels greater delivery of amino acids from your gut to your muscles, and it may also enhance the speed of delivery when compared to an intact protein.[1] As a result, there's less time for the liver to extract crucial amino acids as they flow outward to your muscles.[2,3] For that reason, more amino acids may reach your muscles.

In terms of nutrition and performance, here's how hydrolyzed protein stacks up against other proteins.

Benefit 1: More and Longer-Lasting Amino Acids

Whey protein hydrolysate has a higher leucine content compared to whey isolate: 14.2 percent versus 12.2 percent, to be specific.[4] Given that leucine is essential for "turning on" muscle building, this lift in delivery to your muscles may potentially provide a very slight edge over any other whey form, but the difference is far more pronounced in casein.

Traditional (intact) casein provides a slow, steady increase in amino-acid levels. It doesn't produce a pronounced spike in levels, which is why it's widely considered to be "anticatabolic"take it before bed to stave off muscle breakdownrather than anabolic.

Casein hydrolysate, on the other hand, has been shown to initiate a prominent spike in amino-acid levels similar to whey protein while still maintaining elevated amino-acid levels for the hours to come like that of traditional casein.[5] Even more impressive, a study published in Pharmacological Reviews found a 30 percent greater rise in muscle protein synthesis over a six-hour period when subjects consumed casein hydrolysate versus intact casein.[6]

Benefit 2: Enhanced Glycogen Replenishment

Replenishing glycogen with carbohydrates post-workout enhances the recovery process and prepares your body for your next workout, particularly if you're an athlete doing two-a-days or something similarly demanding.

Glycogen replenishment is fueled by insulin, which is robustly stimulated in the presence of carbs, but also stimulated in the presence of protein alone. Whey hydrolysate induces a substantially greater insulin response compared to intact proteins (isolate or concentrate), which may facilitate superior glycogen replenishment and a greater anabolic response when consumed post-workout.[7]

However, it's worth mentioning that according to a study published in the journal Amino Acids, the difference between hydrolysate and isolate was not noteworthy until 40 minutes. This may or may not be beneficial so far removed from a workout; more research is certainly needed to discern the implications and potential benefits.

Research conducted in mice and cell cultures demonstrated that consuming a whey hydrolysate and carbohydrate combination post-workout significantly increased glycogen replenishment two hours after the workout compared to a whey-isolate/carbohydrate combination and a branched-chain amino acid (BCAA) carbohydrate combination.[8]

Although this research has only been done in mice and cultures at this point, the authors speculate that similar findings would be found in human studies.

Benefit 3: Faster Recovery

A study published in the Journal of Science in Medicine and Sports found that subjects consuming whey hydrolysate post-workout experienced better recovery and performance shortly after a muscle-damaging bout of exercise than those consuming whey isolate.[2] Researchers had 28 subjects complete 100 eccentric-focused repetitions on the leg extension. An eccentric focus induces significantly more muscle damage than typical concentric movements.

Immediately following exercise, subjects consumed either 25 grams of whey hydrolysate, 25 grams of whey isolate, or a protein-free placebo. Recovery was assessed via blood markers, subjective ratings, and performance testing. Measures were completed 1, 2, 6, and 24 hours post-testing.

The whey-hydrolysate group was able to regain performance (measured as peak isometric torque) 6 hours later, whereas the placebo and whey isolate group had not yet fully recovered even 24 hours later. That's a serious difference!

Benefit 4: Improved Intra-Workout Performance

Several studies have observed the effect of consuming casein hydrolysates in addition to carbohydrates during endurance-based exercise.[9-11] Benefits observed include a greater net protein balance, increased time-trial performance, and workout-recovery support.

Though more research is needed on intra-workout protein consumption, these studies represent promising evidence in support of consuming a rapidly-digested protein during your workout.

Hydrolysate's Time Has Come

Today, there's significantly more research available looking at the impact of protein hydrolysates compared to 10 years ago.

And although we don't have definitive reasoning to ditch whey isolates, whey concentrates, or traditional casein, we do have information that suggests choosing a hydrolysate may be advantageous in specific situations:

Intense, frequent training: If you train twice per day, a whey hydrolysate may be advantageous to attenuate muscle damage and replenish glycogen quickly so that you're as close to 100 percent as possible for your second workout.

When dieting: For those deep into a dieting phase, choosing a whey hydrolysate post-workout may be advantageous to promote recovery in the presence of limited carbohydrates. It may also help you to maximize the muscle-building response with fewer calories, given than it has a significantly higher leucine content compared to whey isolate.

During long-duration training: If you're about to embark on a lengthy endurance workout, a casein hydrolysate may help to attenuate muscle breakdown and enhance overall performance.

Hydrolyzed Protein: Understanding the Process and Benefits

Hydrolyzed Protein: Understanding the Process and Benefits

Hydrolyzed protein has been gaining in popularity among athletes and fitness enthusiasts as a highly effective source of protein for muscle building and recovery. This article will delve into the process of hydrolysis, how it is produced, the different types of hydrolyzed protein, and the benefits of consumption. Additionally, we will explore the scientific studies on the efficacy of hydrolyzed protein and potential side effects. Finally, experts will share their opinions on the safety and effectiveness of consuming hydrolyzed protein and provide some recipe ideas for healthy meals and snacks.

What is Hydrolyzed Protein and How is it Produced?

Hydrolyzed protein is a type of protein powder that is created by breaking down large protein molecules into smaller peptide chains, which are easier for the body to digest and utilize. This process is called hydrolysis, and it involves the use of enzymes or acid to denature the protein and break it down into smaller fractions.

Hydrolyzed protein can be produced from a variety of sources, including whey, casein, soy, and collagen. The source of the protein can impact the nutritional profile and amino acid composition of the resulting hydrolyzed protein powder. Hydrolyzed whey protein, for example, is high in branched-chain amino acids (BCAAs), which are essential for muscle growth and recovery.

Hydrolyzed protein is commonly used in sports nutrition supplements, as it is absorbed more quickly by the body than other forms of protein. This makes it an ideal choice for athletes and bodybuilders who need to quickly replenish their muscles after a workout. Additionally, hydrolyzed protein is often used in medical nutrition products, as it is easier for people with digestive issues to tolerate and absorb.

The Science Behind Hydrolysis: Breaking Down Protein Molecules

Hydrolysis is a chemical process that involves breaking down large protein molecules into smaller peptide chains. This process can occur naturally through the action of digestive enzymes in the stomach and small intestine, or it can be induced through the use of enzymes or acid during the manufacturing process.

The goal of hydrolysis is to reduce the size of the protein molecules, which can improve the digestion and absorption of the protein into the body. Hydrolyzed protein is essentially a pre-digested form of protein that requires less energy and digestive enzymes to break down and utilize compared to intact protein.

Hydrolysis is commonly used in the food industry to improve the nutritional value and functionality of protein-rich foods. For example, hydrolyzed whey protein is often added to sports supplements and protein bars to enhance their amino acid profile and improve their digestibility.

However, it's important to note that not all hydrolyzed proteins are created equal. The degree of hydrolysis, or the extent to which the protein is broken down, can vary depending on the manufacturing process and the specific enzyme or acid used. This can affect the quality and bioavailability of the resulting hydrolyzed protein.

Types of Hydrolyzed Protein: Whey, Casein, Soy, and More

Hydrolyzed protein can be produced from a variety of sources, including whey, casein, soy, and collagen. Each source of protein will have a distinct nutritional profile and amino acid composition, which can impact the effectiveness of the hydrolyzed protein for different purposes. For example, hydrolyzed whey protein is popular among athletes and bodybuilders due to its high BCAA content, while hydrolyzed collagen is often used for skin and joint health due to its high concentration of glycine and proline.

Other types of hydrolyzed protein include:

• Hydrolyzed casein protein
• Hydrolyzed soy protein
• Hydrolyzed beef protein
• Hydrolyzed pea protein

Each type of hydrolyzed protein has unique benefits and applications, and it is important to consider your individual goals and preferences when selecting a product.

Hydrolyzed whey protein is a popular choice for those looking to build muscle mass and improve athletic performance. This is because it is quickly absorbed by the body, providing a fast source of amino acids to support muscle growth and repair. In addition, hydrolyzed whey protein is often low in lactose, making it a good option for those with lactose intolerance.

Hydrolyzed soy protein, on the other hand, is a good choice for vegetarians and vegans looking to supplement their protein intake. Soy protein is a complete protein, meaning it contains all nine essential amino acids that the body cannot produce on its own. It is also a good source of antioxidants and has been shown to have potential health benefits, such as reducing cholesterol levels and improving heart health.

Differences Between Hydrolyzed and Regular Protein Powders

Hydrolyzed protein differs from regular protein powders in a few key ways. First, hydrolyzed protein has undergone a chemical process to break down the protein molecules into smaller peptides, while regular protein powders are typically made by removing the fat and carbohydrate components of the protein source.

Additionally, hydrolyzed protein is pre-digested, which means it requires less energy and digestive enzymes to break down and utilize compared to regular protein powders. Hydrolyzed protein is also typically faster-absorbing than regular protein powders, which can make it a better choice for post-workout recovery or other times when rapid absorption is desired.

Benefits of Hydrolyzed Protein for Muscle Building and Recovery

Hydrolyzed protein is a highly effective source of protein for muscle building and recovery due to its rapid absorption and high concentration of BCAAs. BCAAs are essential amino acids that play a crucial role in muscle protein synthesis and repair. Consuming hydrolyzed protein after a workout can help to stimulate muscle protein synthesis and enhance recovery.

Additionally, hydrolyzed protein may be useful for individuals with compromised digestive function, as it is pre-digested and requires less energy to break down and utilize. This can be especially beneficial for older adults or individuals with digestive disorders.

Hydrolyzed Protein and Digestion: Improved Absorption and Gut Health

Hydrolyzed protein may also offer benefits for gut health and digestion. The smaller peptides in hydrolyzed protein are less likely to cause digestive discomfort or bloating compared to intact protein, making it a better choice for individuals with sensitive digestive systems.

Hydrolyzed protein may also help to improve the absorption of other nutrients, such as carbohydrates and fats. This can be particularly beneficial for athletes and active individuals who need to replenish glycogen stores and support overall energy balance.

How to Incorporate Hydrolyzed Protein into Your Diet and Training Regimen

Hydrolyzed protein can be incorporated into your diet and training regimen in a variety of ways. It can be consumed post-workout in a shake or smoothie, or it can be added to meals or snacks throughout the day to increase your overall protein intake. You can also try using hydrolyzed protein in baking or cooking to create protein-packed snacks and meals.

It is important to follow the recommended dosage on the product label when consuming hydrolyzed protein, as excessive consumption may lead to adverse effects such as digestive discomfort or kidney damage.

Potential Side Effects of Consuming Hydrolyzed Protein
