What Is Collagen and Why Do We Need It?

​Collagen is the most plentiful protein in your body and is found in nearly every tissue, including your muscles, bones, tendons, and skin. Therefore, getting enough of it is crucial for your health and well-being.

In total, there are at least 16 types of collagen. Collagen type I, however, is the most abundant one, along with type II, and III making up around 90% of all bodily collagen (1).

This type of collagen plays a crucial role in the structure and strength of skin, teeth, fibrous cartilage, tendons, and connective tissues. Think of it ​as the glue that holds your body together.

How can you make sure you get enough collagen? Well, the best way is by consuming organ meats and connective tissues, as those are the richest dietary sources of collagen. But since most of us rarely eat these parts of the animal, we tend to under consume collagen, which can impair health and well-being.

The Benefits of Consuming Collagen 

Since collagen is the most plentiful protein in our body, it’s obvious it plays a crucial role in health and well-being. Here are just a few of the many benefits of consuming ​collagen:

  • Enhanced Weight Loss 

Collagen is made up of roughly 90% protein. And since protein is highly satiating, adding extra collagen to your diet can satisfy hunger, decrease total calorie intake, and thereby aid weight loss.

For example, one study found that when subjects raised their protein consumption from 15% to 30% of their daily calorie intake, they unconsciously consumed, on average, 441 fewer calories per day. This led to an average weight loss of 11 pounds in just 12 weeks! (2).

And while “regular” protein effectively curbs hunger, collagen protein is even more satiating. Thereby, collagen protein should be even better at helping you obtain and maintain your ideal body weight (3).

  • Improved Skin Tone and Reduction of Cellulite: 

Consuming collagen can improve the radiance of your skin by increasing skin moisture and collagen density.

The overall collagen content of the skin surface declines 1% per year (4).

When the main collagen in your skin (type I collagen) declines, your skin becomes wrinkled, saggy, and you start to develop cellulite. Supplying your body the collagen it needs can help reduce the appearance of cellulite.

  • Better Digestion

Collagen can prevent intestinal damage, improve gastric acid secretions, and enhance the lining of your digestive tract. As a result, you’ll enjoy better digestion and nutrient absorption and decrease your likelihood of suffering leaky gut and digestive problems such as acid reflux, indigestion, and bloating.

  • Less Joint Pain

Because collagen is one of the best sources of the amino acid proline, which is crucial for the stability of collagen in your joints, adding it to your diet can aid joint health. So, if you currently suffer from achy joints, increasing your collagen consumption may alleviate your discomfort.

  • Improved Hair Quality

Research published in the Journal of Applied Cosmetology found collagen supplementation improved hair growth and thickness (5).

  • Enhanced Muscle Growth and Recovery

The importance of collagen in aiding the recovery and growth of muscles is well-known among athletes. And since collagen consists of nearly 90% protein, adding it to your diet can support muscle growth and recovery as well as improve athletic performance (6, 7).

  • Better Mental Health

Collagen is loaded with the amino acid glycine, which reduces anxiety, promotes calmness, and improves sleep quality. Besides, one study published in the Journal of Cell Biology found collagen can promote the formation of neural synapses, and thereby potentially protect you from schizophrenia (8).

The Causes of Collagen Loss

Collagen loss can occur because of internal and external circumstances.

​Internal and natural causes include ​aging, eating a high-sugar diet, nutrient deficiency or genetic susceptibility (9, 10, 11, 12).

Therefore, to maintain our collagen level and optimal health, we need to supply our body the collagen it requires by eating collagen-rich foods and adding collagen supplements to our diet.

The easiest and most convenient way is to supplement with collagen protein powder supplements.  

The Different Types of Collagen Protein Supplements

There are three main variations of collagen protein supplements you can choose from:

  • Unhydrolyzed collagen protein is the non-processed form of collagen. The amino acids in this collagen protein are in their full-length form and tightly twisted into each other. This makes unhydrolyzed collagen protein very strong and durable. After all, this form acts as the glue that holds your body together. But since unhydrolyzed collagen is so tough, we can’t effectively break it down and use it. That’s why this form is ineffective as an oral supplement.
  • Collagen peptides, also known as collagen hydrolysate, have a higher bioavailability compared to both unhydrolyzed collagen protein and gelatin. The reason is that collagen peptides have undergone hydrolyzation, a process that breaks down the amino acids into smaller molecules. As a result, collagen peptides are better absorbed into your bloodstream and are better able to provide you with a myriad of health benefits. If you’re looking for a collagen supplement, it’s best to choose a product that contains 100% collagen peptides.
  • Gelatin is a collagen protein that has undergone partial hydrolysis, leaving a gel that only dissolves in hot water (so it’s not optimal to use in smoothies). Because gelatin has undergone partial hydrolysis, the peptides aren’t entirely broken down and thereby not as well absorbed as collagen peptides. Since the chains of the amino acids in gelatin are only partially hydrolyzed, this product can cause water retention. That’s why consuming gelatin can lead to intestinal discomfort and bloating.

Bottom line: When choosing a collagen product, choose one that contains collagen peptides (collagen hydrolysate). This variation has a superior absorption rate and can best provide all the fantastic health benefits collagen has to offer.

The Problem with Most Collagen Peptide Protein Powders

Most collagen protein powders on the market are of terrible quality and contain compounds that can actually hamper your health and well-being. Why?

One of the main reasons is that most powders are derived from grain-fed chickens. These high-stress environments impair collagen quality and integrity. Besides, many products are loaded with sugar, fillers, binders, sweeteners, and coloring agents that impair ketosis and health.

How to Select the Best Collagen Peptide Protein Powder

Collagen peptide protein powder must meet a few criteria to optimally supply you with the fantastic health benefits this nutrient can provide.

Look for bovine collagen peptides.

First off, when it comes to buying collagen supplements, the product should be derived from cattle (not chickens!). Why? Because cattle have a superior amino acid profile. It contains significantly higher amounts of the amino acid glycine, which promotes calmness, improves sleep, and reduces anxiety along with many other health benefits (13, 14, 15, 16).

Besides, cattle collagen contains a lot more proline, an amino acid that aids the production of hydroxyproline, which your body needs to make collagen, tendons, ligaments, other connective tissues and heart muscle.

Choose grass-fed or pasture-raised sources.

Secondly, the collagen must come from grass-fed or pasture-raised cattle. Not only does this mean the animals live in better conditions, but it also improves the quality of the collagen.

Make sure your product does not contain harmful additives.

Thirdly, the product must be free of soy, binders, sweeteners, and coloring agents.

If you are following a low carb ketogenic diet, your collagen supplements need to be keto-friendly and made with real ingredients and flavored with real foods, not cheap artificial flavors.
