The Definitive Collagen Review 2024

Collagen Is Sold Everywhere These Days… But Which One Is The Best?

We all long for the fountain of youth. Looking good and feeling great has never been so accessible. Most are aware of the vital importance of collagen these days:

30%
of the protein in your body is collagen.
70%
of the protein in your skin is collagen.
We Lose 50%
of our bodies collagen by age 60

With various supplements, we can reconstruct and preserve our bodies to our heart's desire. One such supplement is Collagen, the protein that forms the connective tissue all over our bodies. Collagen is a long chain Amino Acid. It allows the skin to be flexible but also gives it structure.

Collagen comes from the Greek word “glue,” because that’s essentially what it does. It keeps our body together in a meshed matrix of strands that are formed of cartilage, joints, skin, hair, and nails. So much of your body relies on this collagen matrix. If we don’t get enough of it, we break down.

Did you know there are actually over 28 different types of collagen?

Every living animal has collagen, including marine life, birds, and mammals like cows. In each animal, like humans, they have various forms of collagen for different functions as well.

Your body makes its own collagen naturally, but its output starts to seriously decline with age, usually starting in your 20s!

THE FIVE TYPES OF COLLAGEN OUR BODIES NEED MOST

When it comes to supplements there five main types of collagen. We will cover five of them to help you make more informed decisions about your Collagen intake.

  • Type I - This is the most abundant collagen of the human body. It is present in scar tissue, the end product when tissue heals by repair. It is found in tendons, skin, artery walls, cornea, the endomysium surrounding muscle fibers, fibrocartilage, and the organic part of bones and teeth.
  • Type II - This collagen is a protein that helps our joints and cartilage stay cushy and bendy, like a springy cushion for our bones. It's especially important for a type of cartilage called hyaline, which looks all shiny and smooth like glass. But as we get older or strain our joints, we might not have enough type 2 collagen and things can get creaky and ache
  • Type III - Now, type 3 collagen is found in various parts of our bodies, including the skin, blood vessels, and internal organs such as the liver, lungs, intestines and uterous. It's also present in the extracellular matrix, which is a network of proteins and other molecules that provide structural support to our tissues.
  • Type IV - Found in our basement membranes, which act as a barrier and support to our tissues. It forms a mesh-like network that gives the basement membranes their strength and stability, and is especially important for the kidneys, where it helps filter our blood. This Type forms the respiratory tract and that's involved in the bronchial tubes the lungs around the intestines and the tissue around the heart.
  • Type V - Type 5 collagen is a less common protein that helps regulate the formation and assembly of collagen fibers. It's typically found in association with other types of collagen, and is important for the development and maintenance of skin, tendons, and the cornea of the eye. It has been found in the placenta, which is an organ that develops during pregnancy to provide nourishment and oxygen to the growing fetus.

Why We Need to Consume Collagen Supplements

Most people assume that if they eat enough animal protein they will get Collagen in their bodies. The truth is that even if you are eating a lot of meat, it would be very hard for your body to synthesise protein and rebuild it into Collagen. To build Collagen your body requires a lot more to link all the amino chains together.

Chlorophyll from plant food and Vitamin C would have to be present in large quantities to produce collagen directly. And the volume you would need to consume would be impossible.

Using a Collagen Supplement helps you avoid consuming as much protein meat. It’s easier, cheaper, and more effective than shoving down impossible quantities of meat and plants to digest.

With Collagen supplements, you can get close to a 90% absorption rate, while getting collagen from food results in as low as 25-35% absorption. Let's face it, most of us don't eat like Lions, so when we injure a joint, ligament, or tendon, it can feel like our joints aren't bouncing back.

Collagen supplements provide the raw materials for your body that you don’t normally get. Most likely, unless you are eating all parts of the animals you consume, like our primal ancestors, you are likely not getting the amount of Collagen you truly need.

Which Type of Collagen is Best For You?

What Kind?
Source?
Type of collagen?
Marine
fish Scales And Skins
Type 1 only
Bovine
Hides Of Cattles
Type 1 & Type 3
Chicken
Sternum, Bones & Cartliages
Type 2

Bovine Collagen

Naturally sourced from the hides of cattle, this kind is very high in collagen Types 1 and 3 and contains a high amount of protein. In fact, it contains almost double the amount found in marine collagen. With a large amount of glycine, bovine collagen is excellent for hair, skin, nails, as well as our connective tissues and digestive health. In most cases, bovine collagen will give you the best bang for your buck and is often called the fountain of youth

Marine Collagen

Naturally sourced from the scales and/or skins of marine species (usually cold water fish like cod or salmon), marine collagen is very high in Type 1 collagen, which is known to increase tightness, tone, and skin elasticity. It is beneficial for skin, hair, and nail health. If you prefer fish-based products, marine collagen is the one for you. The big downside is the fishy taste.

Chicken Collagen

Naturally sourced from chicken sternum cartilages (very high in Type 2 collagen), it is high in Hyaluronic Acid and Chondroitin Sulfate, which are essential for healthy and strong cartilages, joints and ligaments. Chicken Collagen contains a potent amount of hydrolysed collagen which stimulates collagen production in the skin, supports the health of our joints, and keeps the moisture in our skin and lubrication around our joints.

The Good, The Bad, and The Ugly: All Collagen Is NOT Created Equal

With over 300 various collagen supplements on the market, choosing the collagen that is right for you can seem like an uphill battle. When choosing a collagen supplement, always read labels, verify origins of ingredients, or research these important details before making your decision:

THE GOOD - CERTIFIED, ACCREDITED, BEST PRACTICES

Reputable companies will indicate with labels their certifying bodies as well as proper ingredients and manufacturing practices:

  • Gluten-Free, Allergen-Free, and Non - GMO
  • Contains essential Amino Acid profile
  • Premium grade Bovine collagen (type 1 and 3)
  • Good Manufacturing Practice certified
  • MCT oil
  • Dairy-Free, Pasture Raised, Lab Tested
  • Mixes extremely well, best out of all competition
  • Laboratory tested for purity and potency
  • Made in an FDA registered facility
  • Made in the EU
  • Helps your current nutrition goals
  • Tastes great or flavourless.
  • Sourced From Grass-fed Beef (in the case of Bovine Collagen) - You won't find any antibiotics in grass-fed bovine collagen powder. Just 100% premium quality Bovine (type I & III) Hydrolysed Collagen Peptides.
The Bad — Poor Quality, Inconsistency, and Ineffectiveness

Some companies selling collagen do the right thing legally, but they simply have an inferior product, which will not help you, and will be a miserable experience for you:

  • Insoluble - it does not dissolve and is harder to mix
  • An inferior product will have little impact on you and will make for a miserable experience
  • Horrible Taste - strange aftertaste…. Definitely not tasteless
  • Not complete - product to come half empty.
  • Multi-Collagen blends - Too General - Not focused on your essential needs
  • Not consistent - a totally different consistency with each order the granules are different sizes, too large, and not soft powder. The texture, solubility, and even the color are always different and clumpy in liquids of various temperatures
  • No potency - No Results. No effect whatsoever

The Ugly - Lies, Deception, and Product Callbacks

Unfortunately, in every market there are bad actors who cut corners and sell products that have no business being in the market. While it is a bit more rare, it’s still important to be on guard. Collagen is no different, because many companies cut corners to bring supplements to market. Beware! They could be endangering your health:

  • Pesticides: if animals are fed foods high in a certain pesticide it could concentrate in the collagen protein.
  • Contaminants: recent laboratory tests revealed that contaminants such as antibiotics, parabens, and steroids were found in popular collagen products.
  • Not Testing for Metals: the parts of animals used to create collagen supplements can be high in heavy metals. So it's important to make sure that the company you choose tests for that.
  • Cheap Imported Collagen - Using Imports of collagen peptides from Chinese bovine
  • Bacteria: Through an investigation, it has been determined that vials of Collagen packaged within the Collagen Reagent and Platelet aggregation Kit, may contain particulate matter or microbial growth.
  • Recalls because of Additives and Fillers in collagen

2. Revive Collagen by Revive

Grade
B

Pros

  • Contain Hyaluronic Acid
  • Type 1 Hydrolysed Collagen (Marine)
  • Aloe Vera Juice

Cons

  • Does not contain any other collagen type
  • High price point
  • Does not contain a complete amino acid profile

Revive Collagen - Hydrolysed Marine Collagen Drink is our number two pick. These flavoured collagen packets are formulated from type I hydrolysed marine collagen to support skin.

Each packets contains 8.5 g of hydrolysed collagen which can easily be added to any liquid of your choice, making this collagen supplement easy to add to your daily routine.

Our team liked the fact that these collagen packets were easy to take on-the-go however we found that formula lacked crucial ingredients needed to support other areas of the body. Unfortunatley, Revive Collagen does not contain a complete amino acid profile and only contain type I collagen. The short ingredient label paired with the high price point left Revive at number 2 on our list.

3. Collagen Peptides by Vital Proteins

Grade
B

Pros

  • Made in the USA
  • Gluten and dairy-free
  • Certified grass-fed bovine collagen

Cons

  • High in sodium
  • Does not contain a scoop inside

Collagen Peptides by Vital Proteins is formulated with 20g of grass-fed and pasture-raised collagen.

Like our number one choice, Collagen MCT by Primal Harvest, the Vital Proteins formula is easy to use. However, it falls into third place because they do not specify which type of collagen their Collagen Peptides contain. This may mean that it won't meet the needs of all consumers.

Although this unflavoured formula is a solid choice for a collagen, it was disappointing that it has a relatively high sodium content. This is definitely not ideal for those watching their sodium intake. It also makes the product less versatile.

Additionally, this product does not contain a scoop which can cause confusion for many customers when trying to measure their collagen everyday.

4. Absolute Collagen by Maxine Laceby

Grade
C

Pros

  • Contains Vitamin C
  • Contains Type I hydrolysed collagen (Marine)

Cons

  • Expensive entry price point
  • Many customers complained of poor taste

Maxine Laceby's Absolute Collagen comes in at number four on our list. It contains 8g of hydrolysed marine collagen per scoop. Their collagen is sourced from freshwater Basa Fish. Like our top choice, it does not contain gluten, soy, or lactose.

We liked that it had easy packets to bring on-the-go. Although it dissolved fairly easily into cold drinks, we still found that it took longer to dissolve than other collagen powders we tested. Many consumers also reported that the taste was fishy or offputting.

This would otherwise have been a great choice, but the pricing of this product knocks off a few points in our opinion. It’s a shame that this product has a pretty steep entry price point.

5. Marine Ultra Strength Collagen by Reverse Life

Grade
C+

Pros

  • Variety of collagen types
  • Amino acid profile

Cons

  • Users complained of fishy flavour
  • Doesn't mix well

Reverse Life Marine Collagen includes 3g of collagen peptides per scoop, the serving size is two scoops. So in total you would received 6 grams of collagen. This formula is sourced from fish collagen. The container consists of 30 servings of 'neutral' flavoured collagen.

Although we liked that the formula includes an amino acid profile, the formula lacked any other ingredients needed to support hair, skin, joints, and nails. Additionally, we enjoy the versatility of unflavoured, neutral-tasting collagen peptide powders like that of our number one choice. We find that they are easier to implement into a regular daily routine as they can be added to any drink of choice. However, we did see many consumers complaining of a fishy aftertaste of the fish collagen.
