What Is Collagen?

Collagen is the body’s architectural marvel, a protein that acts as the scaffolding for our skin, bones, tendons, muscles, and more. Think of it as the glue holding our body together, providing structure, strength, and elasticity. This abundant protein is primarily composed of amino acids like glycine, proline, and hydroxyproline, forming a triple-helix structure that gives tissues their resilience.

As we age, collagen production naturally declines, leading to wrinkles, joint discomfort, and weakened connective tissues, making collagen supplementation a popular avenue to support vitality and maintain youthful skin and mobility.

Collagen is the most abundant protein in the human body. It accounts for about 1/3 of the body’s protein. _[1]

Benefits & Collagen’s Role In The Body

From rejuvenating skin elasticity to promoting joint flexibility, collagen’s versatile advantages have positioned it as more than just a buzzword in the realms of beauty and wellness.

So what are some potential benefits of collagen? Collagen may…. _{[2, 3}, ₄, _{5, 6, 7]}

• Improve skin elasticity
• Reduce wrinkles
• Improve skin hydration
• Assist with muscle tissue repair and growth
• Supports athletic performance and endurance
• Helps with joint pain and inflammation
• Improve gut health
• Strengthen bones

… and more. The science on collagen is constantly growing and evolving.

A 2021 meta-analysis that analyzed over 19 studies with 1000+ participants show an improvement in skin elasticity, wrinkles, and skin hydration. _[8] Collagen supplements CAN improve your skin!

Different Types Of Collagen Supplements

There are three main types of collagen. Here’s how they differ:

1. Type I
   • Composition: Found abundantly in the skin, bones, tendons, and connective tissues.
   • Structure: Forms dense fibers, providing tensile strength and resistance to stretching.
   • Function: Maintains skin elasticity, supports bone integrity, and contributes to the structure of organs.
2. Type II
   • Composition: Predominantly present in cartilage, the tissue that cushions joints.
   • Structure: Forms a looser network of fibers, giving cartilage flexibility and shock-absorbing properties.
   • Function: Essential for maintaining healthy joints by ensuring smooth movement and preventing friction.
3. Type III
   • Composition: Found in skin, blood vessels, and internal organs.
   • Structure: Forms reticular fibers, which create a supportive framework for organs and tissues.
   • Function: Supports the structure of organs, blood vessels, and skin, contributing to their overall stability and function.

Most collagen supplements contain a mixture of Type I and Type III collagen. When collagen is made from within our cells – this is known as endogenous collagen. If you’re getting collagen from supplements or external sources, that would be known as exogenous collagen.

Is Vegan Collagen Legit?

“Vegan Collagen” is a bit of an oxymoron. There is no true vegan collagen. Collagen is only found in animals, mostly in connective tissue and flesh. Vegan collagen supplements can help to support your body’s natural production of collagen, but it’s not a true collagen supplement.

Different Sources Of Collagen Supplements

There are many different sources of collagen. Let’s dive into the differences:

1 – Bovine Collagen:

• Sourced from cows, specifically the skin, bones, and cartilage.
• Rich in Type I and Type III collagens, which are beneficial for skin, bones, and connective tissues.
• Widely available and often used in various collagen supplements.

2 – Marine Collagen:

• Derived from fish scales, skin, and bones, usually from species like cod or pollock.
• Primarily composed of Type I collagen, promoting skin health and elasticity.
• Absorbed efficiently due to smaller particle size and may have better bioavailability for skin benefits.

3 – Porcine Collagen:

• Extracted from pig skin and cartilage.
• Similar to bovine collagen, containing Type I and Type III collagens that support skin, bone, and connective tissues.
• Used in a variety of supplements for its collagen content.

4 – Chicken Collagen:

• Sourced from chicken bones, cartilage, and skin.
• Typically rich in Type II collagen, beneficial for joint health and cartilage support.
• Can also contain Type I collagen, contributing to skin and tissue health.

5 – Eggshell Membrane Collagen:

• Derived from the membrane between egg white and shell.
• Contains collagen Type I, Type V, and other compounds like hyaluronic acid and chondroitin sulfate.
• Known for supporting joint health and potentially improving skin appearance.

6 – Synthetic Collagen:

• Created in laboratories using recombinant DNA technology.
• Designed to mimic natural collagen’s structure and properties.
• Still in experimental stages and not widely available for commercial use.

7 – Plant-based Collagen Options

• These are collagen alternatives – they’re not true collagen
• Created using extracts from plant sources rich in nutrients that support collagen production.
• Often includes vitamins, minerals, and antioxidants that promote skin health and collagen synthesis.
• Suitable for individuals looking for vegan or vegetarian alternatives to animal-derived collagen.
• Some companies will include a mix of different collagen sources.

Is Collagen Sourcing Ethical?

Collagen sourcing can present ethical considerations depending on the source and production practices. Animal welfare, sustainability, and the environmental impact all play an important role. Most traditional collagen supplements source animal products from factory farmed animals, which are abused and sick. This is why it’s essential to support pasture-raised and grass-fed brands.

Collagen Bioavailability

Collagen bioavailability refers to the body’s ability to effectively absorb and utilize the collagen present in supplements or foods. The bioavailability of collagen is influenced by factors such as the source of collagen, its molecular structure, and the processing methods used. It’s not fully bioavailable, meaning it’s not always fully absorbed by our bodies.

Smaller collagen peptides, often obtained through hydrolysis, tend to have higher bioavailability as they can be easily broken down and absorbed by the body. Consuming collagen with vitamin C-rich foods can also enhance its bioavailability, as vitamin C supports collagen synthesis and absorption.

Is Marine Collagen More Bioavailable Than Bovine Collagen?

Marine collagen is often considered to have higher bioavailability compared to bovine collagen, primarily due to its smaller particle size and unique composition. The smaller size of marine collagen peptides allows for easier absorption in the digestive tract, potentially leading to better uptake by the body.

This is particularly relevant when considering skin-related benefits, as marine collagen is commonly associated with promoting skin health and elasticity. It’s important to note, though, that bioavailability can also be influenced by an individual’s unique metabolism and digestive system, as well as the specific manufacturing methods used in collagen supplements.

What Is Hydrolyzed Collagen?

Hydrolyzed collagen, also known as collagen peptides or collagen hydrolysate, is a type of collagen that has undergone a process called hydrolysis. In this process, large collagen molecules are broken down into smaller peptide chains through the application of enzymes or heat. The resulting collagen peptides are easier for the body to absorb and utilize compared to intact collagen fibers.

Hydrolyzed collagen, also known as collagen peptides or collagen hydrolysate, is a type of collagen that has undergone a process called hydrolysis. In this process, large collagen molecules are broken down into smaller peptide chains through the application of enzymes or heat. The resulting collagen peptides are easier for the body to absorb and utilize compared to intact collagen fibers.

Usually, hydrolyzed collagen can be dissolved in hot or cold liquid without clumping.

Is Gelatin A Good Source Of Collagen?

While this is a great thought, gelatin is a degraded form of collagen so it’s not nearly as bioavailable. You’ll likely get some collagen from gelatin, but it’s certainly not a better source.

Is Vegan Collagen As Beneficial As Regular Collagen?

The short answer: they’re not as good… but they can still be beneficial.

Vegan collagen alternatives are not technically collagen themselves, as they do not contain animal-derived collagen peptides. Instead, they often contain plant-based nutrients that support the body’s own collagen production.

While they can offer benefits by providing essential nutrients for skin health, joint function, and overall well-being, they might not have the exact same effects as traditional collagen supplements.

Do Collagen Creams Work?

Topical collagen creams are all the rage now-a-days. They may provide some temporary (key word: temporary) benefits for the skin’s appearance and hydration due to their moisturizing properties. However, the effectiveness of collagen creams in directly replenishing or boosting collagen levels in deeper skin layers is limited.

Collagen molecules are too large to penetrate the skin effectively, so while these creams can improve surface hydration and texture, they may not significantly impact the body’s natural collagen production or long-term skin health.

The body will prioritize its collagen use for essential functions. The skin is usually the last to be affected.

Potential Collagen Powder Side Effects

There are some potential collagen powder side effects to be aware of:

• Intestinal discomfort
  • If you have a particularly sensitive stomach, it’s best to take collagen supplements with food.
• Can contain contaminants, if it’s not properly sourced
• Allergic reactions
  • If you’re allergic to fish, do NOT use marine collagen!
• Side effects are unknown for pregnant and breastfeeding women. It’s best to speak with your doctor and err on the side of caution.
• Speak with your doctor first if you’re on medication or have a pre-existing condition

Of course, if you’re vegan, do not use true collagen supplements.

The efficacy of collagen supplements is controversial. There are studies that support collagen’s efficacy, and others that support the opposite.

The collagen industry is worth about 2.8 billion dollars and they’re sold in powder, liquid/drinks, pills, and gummies. _[9]

Do Organic Collagen Supplements Exist?

No, there is no United States Department of Agriculture (USDA) standard for organic collagen supplements. This is why it’s essential to do your due diligence to make sure you’re getting a supplement from the highest-quality brand.

Other Ways To Increase Collagen & Protect Your Skin

Besides taking a supplement, there are other ways to increase your collagen and improve your skin, such as:

• Get enough Vitamin A, Vitamin C, Vitamin D, and Zinc – these are essential for the production of collagen
• Opt for foods and supplements rich in antioxidants, like turmeric/curcumin

What To Look For When Shopping For Collagen

When shopping for a collagen supplement, look for the following:

• Most important: third party tested for heavy metals – we want these levels to be low!
  • Some brands will refuse to send a Certificate of Analysis because the information is “proprietary.” This is simply not true (take it from someone who used to work in the Regulatory Quality field & would review COAs day after day). Companies can redact (black-out) certain areas of their COAs if something is truly proprietary.
  • The levels of heavy metals in a final product is NOT a “brand secret.”
• Grass-fed, pasture-raised bovine or wild-caught marine
• Sugar free, Dairy free, Non-GMO, Preservative-free
• Free of added sugar and sweeteners (including stevia)
  • Learn more about stevia here: Is Stevia Safe?
• Unflavored (to avoid any undisclosed natural and artificial flavors)
  • Avoid any brands that use stevia. Learn more about why here: Is Stevia Safe During Pregnancy… Or At All?
• Proposition 65 compliant
  • Learn more about Proposition 65 here: What Is Proposition 65 In California? Prop 65 Explained

The quality of your supplement is key.

Better Collagen Brands

The collagen brands in this category are either not grass-fed or pasture-raised.

1 – Puori – CP1 (Best for low heavy metals)

Their heavy metal testing results are directly on their website (which is great)! No detected Arsenic, Cadmium, Mercury, or Lead in their products – this is amazing and nearly unheard of. _[13] It does raise a bit of a too-good-to-be-true scenario in my head, but I’ll take their test results as they are.

• Tested by a 3rd party laboratory & you can view all results on the Clean Label website _[14]
• No detected Arsenic, Cadmium, Mercury, or Lead in their products – this is amazing! _[15]

3 – Native Path – Collagen Peptides

They quickly sent me their COA from August 2022 which shows 0.8 ppm Arsenic, 0.5 ppm Mercury, 0.5 ppm Lead, and 0.5 ppm Cadmium. These heavy metal results are a bit higher than others, hence why they’re in the “better” category instead of best.

• Sourced from grass-fed and pasture-raised bovine

4 – Just Ingredients – Bovine Collagen Peptides

They quickly sent me their COA from July 2023 which shows under 0.001 ppm Arsenic, 0.002 ppm Mercury, 0.004 ppm Lead, and under 0.001 ppm Cadmium.

Their heavy metal testing results are directly on their website (which is great)! Their March 2022 manufacturing date shows no Arsenic, 0.1 ppm of Mercury, under 3 ppm of Lead, and 1 ppm of Cadmium. _[19]

• Remember: this is not a true collagen powder (which is why it’s in the “better” and not best category)
• It’s third-party tested and test results are available directly on their website _[20]
• Contains a mixture of organic pea protein, acerola cherry extract, aloe vera, bamboo, etc…
• It does contain coconut sugar, which should be limited

7 – Trace Minerals – Collagen Peptides

They agreed to physically mail me a copy of their COA (like they did for their mineral supplement). They refused to send the heavy metal information via email. Update August 17, 2023: I received their physical COA in the mail. The results showed 0.037 ppm Arsenic, 0.001 ppm Mercury, 0.009 ppm Lead, and 0.001 ppm Cadmium.

• Sourced from grass-fed bovine
• Includes ConcenTrace Trace Mineral Complex, which I talk about in my minerals article. Read more about mineral supplements here: The Best Mineral Drops For Reverse Osmosis Water (main reason it’s in the “better” category)

8 – Promix – Unflavored Collagen

Their test results are directly on their website, however, it’s one report without a date or disclosed tested flavor (this is not a trust COA). The result shared showed Arsenic was under 10 ppb, Mercury was under 5 ppb, Lead was under 5 ppb, and Cadmium was under 10 ppb. This is the same information shared for their protein powders too.

• Grass-fed
• Opt for their unflavored version. Their flavored versions contain coconut sugar.

9 – Truvani – Collagen Peptides

They shared with me a test results web page that explains that they test each ingredient and finished product for heavy metals, although the most recent COAs are not included on this page. _[21] I’m a fan of the Truvani brand, Truvani’s founder, and they are apparently working to share test results in a more transparent way, but they refused to share “due to legal reasons.” Although, I’m keeping them at the bottom of the “better” category because I know how much the founder is focused on creating high-quality products.

• Sourced from grass-fed Argentinian Cattle (Bovine)
• Also sells marine collagen

9 – Organifi – Collagen

They responded by saying their COA is available on their website, but upon reviewing the page the collagen is not included. I followed up with more information and they said they are following up with their product team. I’m waiting on more information.

• Not grass-fed, pasture-raised, or wild-caught
• Contains Proposition 65 warning label on the package
