There are many different types of liquid protein supplements on the market, and it can be hard to know which one is right for you.

Liquid protein supplements are a great way to get the nutrients your body needs without feeling bloated or sick. This guide will help you choose the best product for your needs and explain how to take it safely and effectively.

What are Liquid Protein Supplements?

Liquid protein supplements are specially concentrated forms of protein that you can consume to fulfill your daily nutrient requirements. Perfect for those in need of a high-protein diet but may be unable to consume solid foods or meet their protein goals through natural sources like meat, fish or grains.

Medline Active Liquid Protein, for instance, offers a whopping 15 to 16 grams of protein in a single 1-ounce serving. No need for blending or mixing, and it goes easy on your tummy. Just uncap, pour and sip. It's also low in calories and can provide essential muscle support.

Such liquid supplements are a fuss-free, effective way to boost your protein intake.

1. Best Medical Grade: ProT Gold Oral Protein Supplement

You’d agree that the ProT Gold Oral Protein Supplement is a top-tier liquid protein supplement. It's packed with 17.5 grams of concentrated protein per ounce serving, and its ready-to-use formula makes it a favorite amongst all who use it.

I appreciate that is uses collagen protein as the main protein source, but they fortify it with other single amino acids to cover your protein needs.

I also like that it uses ingredients specifically designed to support wound care, setting it apart from its competitors.

ProT Gold Oral Protein Supplement

Ingredients: Water, collagen protein, citric acid, arginine, natural flavor, taurine, tryptophan, histidine, methionine, glutamine, sucralose, malic acid, sodium benzoate, potassium sorbate, cysteine.

The high protein content is great if you want to retain muscle after surgery or while in care. And the ready-to-drink nature makes it convenient for travel and if you are on-the-go.

Catering to a broader audience, it's gluten and lactose-free, making it a suitable choice for individuals with specific dietary restrictions. And if you are watching your calories while you recover, it is low calorie. There is also sugar free versions for diabetics.

I found ProT Gold to taste ok, not the best. It is quite thick, but it helps me reach my daily protein target with ease.


2. Best Savory Protein: Bluebird Provisions Chicken Bone Broth

If you are in search of the most delectable bone broth powder available, your search ends with Bluebird Provisions. This convenient bone broth offers a delightful and authentic chicken flavor.

When prepared, it has 12 grams of protein per cup, without any fat or carbohydrates. Keep in mind that the protein in bone broth is not considered a complete protein, so you cannot rely on it for all of your protein / amino acid needs.

Bluebird Provisions Chicken Bone Broth

It is made solely from pasture raised chicken bones and water, without any fillers, gums or flavor enhancers. Additionally, this particular bone broth mixes exceptionally well and stands out as the only one on the market to utilize a pouch that is completely recyclable.

What I find particularly appealing about it is its high protein content of 12 grams protein per cup, eco-friendly packaging that can be recycled entirely and its potassium level of 300 mg per cup, as well as being low in sodium at just 130 mg per cup.

I've been using this bone broth brand for a few years now, and really appreciate that it is a concentrated broth that is easy on my stomach.


3. Best Water: Vital Proteins Collagen Water™

When it comes to choosing the best liquid collagen protein supplement, Vital Proteins Collagen Water™ definitely stands out from the crowd.

It is an ideal source of hydrolyzed collagen in a convenient bottle to fuel your active lifestyle. And unlike most other ready-to-drink protein drinks, this one actually tastes great.

I found the flavor to be subtle and not overly sugary or artificial tasting like other brands. It works for me when I'm travelling or have a long day out.

Vital Proteins Collagen Water™

Top features:

  • Supplies 10g of hydrolyzed collagen per bottle
  • No artificial sweeteners
  • Uses filtered, reverse osmosis water
  • Dairy and gluten-free
  • Convenient, ready-to-drink format
  • Variety of flavors (lemonade, fruit, blackberry, strawberry lemon, lemon slice)

At between $2-3 per bottle, it might be a bit pricey for some people, but it is the most premium liquid collagen on the market.

I'll not that this product is not vegan friendly.


4. Best Protein Supplement: Jocko Molk Chocolate Protein Shake

Jocko Molk Chocolate Protein Shake is your ideal protein supplement, blending quality with taste like no other. Look no further for a just-right combo of muscle replenishment and taste explosion.

I was pleasantly surprised my the flavor of the chocolate shake. It tastes chocolatey without the chalkiness of other protein shakes.

I appreciate the high quality grass fed proteins with milk protein (whey and casein) and the fact that it is keto friendly with only 5 grams of carbs (1 g sugar).

Jocko Molk Chocolate Protein Shake

Ingredients: Water, milk protein isolate, calcium caseinate, monk fruit extract, fermented cane sugar, natural flavor, sea salt, organic locust bean gum, high oleic sunflower oil, cellulose gum, cellulose gel, sunflower lecithin, sodium phosphate, gellan gum, potassium citrate, potassium salt, alkalized cocoa.

The two cons are that it is a bit on the pricey side if you are using them regularly. But with supplements, you get what you pay for. The other downside is that if you have a lactose or dairy allergy, then this is not for you.


5. Pro-Stat Concentrated Liquid Protein Medical Food

Pro-Stat Concentrated Liquid Protein Medical Food is the top choice for medical needs.

One of the standout products in the protein supplement market is this concentrated liquid protein. It boasts rapid absorption and complete bioavailability, ensuring that users get maximum benefits. 

Each serving, which is just 1 ounce, delivers an impressive 15g of collagen protein. For those concerned about allergens and dietary restrictions, this product shines as it's free from soy, lactose, whey, dairy and gluten. 

Its versatility is evident as it's suitable for both oral consumption and tube feeding.

Key Ingredients: Hydrolyzed Collagen Protein, Water, Glycerin, Malic Acid

The thing to keep in mind is that Pro-Stat uses collagen protein, which is an incomplete protein source. This means that you cannot rely on this beverage to cover your protein needs.

You need protein with essential amino acids in order to survive.

- Requires refrigeration after opening, which may not be convenient for everyone

- Allergen-free composition

- Taste may not be liked by everyone

- Versatility for oral intake

- Caution needed for individuals with specific medical conditions due to high protein content

and tube feeding

- Premium pricing may be a deterrent for budget-conscious individuals

When I tried it myself, I noticed that it tastes slightly sweet, kind of like kool-aid. It mixes well and did not have any aftertaste or anything.


6. Active Liquid Protein Nutritional Supplement

Active Liquid Protein Nutritional Supplement, Sugar-Free, Berry Flavor is touted as one of the best for its concentrated dose of protein. 

I've personally been using this concentrated protein supplement, and it's been a game-changer for my active lifestyle. Each 1-ounce serving delivers a solid 15g of protein, which is perfect for those post-workout muscle recovery moments. 

What I particularly appreciate is its sugar-free composition, ensuring I'm not loading up on unnecessary calories. The dual protein source, combining hydrolyzed collagen and whey protein, offers a comprehensive protein profile. 

Active Liquid Protein Nutritional Supplement

Ingredients: Protein (from collagen hydrolysate, L-Leucine, L-Trytophan, Whey Isolate, L-Histidine, L-Isoleusine, L-Threonine and L-Methionine), purified water, sucrose, natural flavors, citric and malic acid, sodium acid sulfate, phosphoric acid, potassium sorbate and sodium benzoate (preservatives), red #40

For those with dietary restrictions, it's a relief to know that it's both lactose-free and gluten-free. But whey can cause some issues if you are sensitive to dairy.

But the standout feature for me? No refrigeration required. This means I can toss it in my bag and use it on-the-go, especially after an impromptu workout or game.

If you're vegetarian or vegan, then this is not for you due to its whey protein content. Also, it contains artificial flavors, which might be a concern for some.

Lastly, taste is subjective, and its specific flavor might not resonate with everyone's palate. I found that it tasted fine.


Benefits of Liquid Protein Supplements and Powders

The benefits of liquid protein supplements are that they are convenient, easily digestible protein sources, may help repair muscles and tissues, may improve muscle strength, can reduce fatigue, reduce muscle soreness and they may relieve constipation or diarrhea.

Let's dive into each of these in more detail.

1. Easily Digestible Source of Dietary Protein

Offering an easily digestible source of dietary protein, liquid protein supplements give you a convenient alternative. This is especially true if you find traditional protein sources challenging, especially post-surgery or for those with swallowing difficulties. 

Unlike their solid counterparts such as chicken or eggs, liquid proteins streamline the digestion process, ensuring the body receives its protein dose without any hitches.

2. May Help Repair and Strengthen Tissue

Liquid protein supplements can play a vital role in tissue repair and strength. Rich in essential amino acids and hydrolyzed protein, these potent supplements speed up recovery.

The magic lies in their enhanced protein bioavailability. For instance, a mere 1 ounce serving can provide a robust 15 grams of protein.

These supplements are also champions of skin health. Their patented blend is designed to not only promote skin regeneration but also to bolster skin elasticity, preventing breakdown. 

Mix them in your favorite drink or consume directly for rapid absorption. Choose these protein power boosters for faster tissue repair and wound healing.

3. May Improve Muscle Strength and Performance

Liquid protein supplements and powders can significantly boost your muscle strength and performance.

The reason behind their efficacy lies in the concentrated protein they deliver. Muscles, by nature, are heavily reliant on adequate protein for their sustenance and growth.

When this protein is consumed in liquid form, your body can digest and absorb it at a much faster rate, ensuring that your muscles receive their protein fix promptly.

The benefits are supercharged when combined with resistance exercise or weight lifting. Post-workout, as muscles undergo wear and tear, these supplements step in to expedite the repair and recovery process, effectively reducing the dreaded muscle soreness that often follows intense exercise. See below for more.

4. May Help Reduce Fatigue and Muscle Soreness

Delving into the science behind it, intense workouts lead to minuscule micro-tears in the muscle fibers. It's the body's natural repair mechanism to use protein to mend these micro-tears in order to build more muscle.

This is where protein supplements come into play. By offering a rapid, easily digestible source of protein, they expedite the muscle repair process, ensuring you rebound with vigor and experience diminished soreness. 

You're rejuvenated, primed for another round of exercise, all thanks to the transformative power of protein! I find that a post-workout smoothie is the key to recovering quickly and not getting sore.

5. May Help Maintain Normal Body Weight

These protein-packed powerhouses provide essential nutrients your body needs without piling on unnecessary calories. 

An example? Consider a glass of vanilla-flavored whey protein shake. It can offer you just as much protein as a grilled chicken breast but with fewer calories. 

Now, that's a tasty, convenient way to keep your weight in check! Just remember, to truly reap the benefits, these supplements should be part of a balanced diet and regular exercise routine.

6. May Provide Essential Amino Acids and Nutrients

You might struggle to meet your daily protein needs through food alone. A dose of liquid protein supplement or powder could be just what you need to hit the mark.

These supplements can provide essential amino acids and other nutrients to sustain your health and longevity. Here are a few amino acids you can get more of with liquid protein:

  • Aspartic Acid takes the lead in energy production, ensuring you're always charged up.
  • Threonine plays a vital role in maintaining protein balance within the body.
  • Glutamic Acid is the mastermind behind the creation of other amino acids. 
  • Proline is the guardian of skin health, ensuring it remains supple and vibrant.
  • Arginine steps in to promote efficient wound healing, speeding up recovery. 
  • BCAAs: Isoleucine, Leucine and Valine are the powerhouses behind muscle growth and swift recovery.
amino acids

So, the next time you're looking to bolster your protein intake, remember that some of these supplements offer amino acids to keep your body functioning properly.

7. May Help Relieve Constipation and Diarrhea

Liquid protein supplements and powders can be an easy digestive fix for you. But they don't work for everyone.

  • For constipation, they provide needed bulk to help move things along in your digestive system.
  • In the case of diarrhea, they soak up excess water, improving stool consistency.

How to Choose the Right Liquid Protein Supplement or Powder

Here are a few things to help you choose the right liquid protein supplement:

First and foremost, pick a supplement that aligns with your dietary preferences and needs. For instance, if you're treading the vegan path or have dairy allergies, plant-based proteins like pea, hemp or brown rice protein might be your allies.

Next, dive into the protein content. You want to make sure that it has enough to cover your nutritional needs. If you are looking to replace other proteins (meat, fish, etc) with liquid, then you need a complete protein source like whey.

If you just want something extra to help you recover and feel better than a combination of whey, plant based options or collagen might be a better fit.

Look past the protein at the other nutrition information. The sugar, sodium and fiber content deserve attention too. I prefer to not get my fiber from liquids, because I find they make me bloated and I can't eat. But other people are looking for things that satisfy their hunger.

Look for something with less than 200 mg of sodium and less than 5 grams of sugar for the whole bottle.

And as you're about to make your pick, ponder over the convenience factor. While protein powders have their merits, liquid protein supplements might be the perfect fit for those always on the move, offering a quick and easy protein fix.

How to Use Liquids with Protein

  1. Choose your liquid protein supplement of choice and begin taking it in a low dose.
  2. You want to use a low dose to start (like 1 fluid ounce), because you're not sure how your body is going to react to it.
  3. Take note of how you look and feel after taking it and the next day.
  4. Adjust your dosage as needed.

This is especially important if it is a new protein source your body is not used to. Many of these proteins can cause some digestive issues. So let your body guide you.

Potential Side Effects and Risks

Some side effects of liquid proteins are digestive upset, nausea and vomiting and allergic reactions. Let's get into these so that you can learn how to avoid them!

1. Digestive Problems

Your body might have a poor reaction to the protein type of increased intake that can result in issues like bloating, gas or constipation.

These nuisances often arise from our body's response to the sudden surge in protein intake. For starters, you might get some GI discomfort or gas. This is likely your body struggling to process the added protein or a novel protein source (whey, casein, pea, etc).

I personally find that whey protein makes me gassy, so I tend to avoid it. But bone broth protein and pea protein work really well.

Let's not forget the fiber factor. Many protein powders skimp on fiber, an essential component that our gut absolutely adores.

You might also grapple with swallowing difficulties, finding certain protein powders a tad challenging to ingest. I recommend that you do not go overboard with protein supplements. The Metabolic stress states could be a potential concern, putting undue pressure on the metabolism.

2. Nausea and Vomiting

These unsettling reactions can manifest, especially if underlying gut issues like leaky gut or allergies are present.

From a practical perspective, if you take too much too soon, you will increase your risk of being sick. That is why I recommend starting conservatively with your intake.

Space out your doses throughout the day so that your gut gets a chance to become acquainted with the new amino acids.

Also, hydration plays a pivotal role in this equation. Ensuring you're adequately hydrated both pre and post-supplement intake can make a world of difference.

If you have issues, it is best to speak to your primary healthcare physician, doctor or a registered dietician.

Is liquid protein good for you?

In certain scenarios like post-surgery or if you can't swallow food, liquid protein is a great choice and if good for you. In other situations where you have access to other food and the means to prepare it, it is likely not the best option.

Post-surgery or in the lead-up to a weight loss procedure, your body might throw a curveball, struggling with solid food intake. This is where liquid protein shines, offering a cocktail of both essential and non-essential amino acids. 

In these scenarios, they can be instrumental in bolstering tissue and organ strength, paving the way for a swift recovery. But it's not just the post-op crowd that can benefit. 

Endurance athletes, busy people or those grappling with swallowing difficulties, might find liquid protein to be a helpful as well.

And while the allure of liquid protein is strong, don't don't neglect your traditional protein sources. There is no substitute for whole foods.

What is best liquid protein?

The best liquid protein depends on your unique needs. If you are looking for a post-workout protein to cover your nutritional needs or something that tastes great and is keto friendly, then a whey protein or milk protein like Jocko Molk might be the best option.

That being said, if you are preparing for surgery or recovering with surgery, then a medical grade protein like Prot Gold might be the best option.
