In this article, I will explore the benefits of collagen supplements, especially collagen peptides, and provide tips on how to choose the right one for you. I will also select the best collagen peptides for your consideration.

What is Collagen?
Collagen is a protein that is found naturally in the body and plays a vital role in the health of our skin, hair, and joints. As we age, our body's ability to produce collagen decreases, leading to visible signs of aging such as wrinkles, sagging skin, and joint pain. To combat this, many people turn to collagen supplements to help boost collagen production and promote healthy skin, hair, and joints.
How is Collagen Made?
Collagen is naturally found in the skin, bones, and connective tissues of animals, including cows, pigs, and fish. Collagen supplements are typically made from these animal sources, although some vegan collagen supplements are available that are derived from plant-based sources such as mushrooms or algae.
How Many Types of Collagens?
There are 5 Common Types of Collagens:
Type I, is great for tensile strength.
Type II, for stretching in multiple directions (ligaments, organs).
When it comes to collagen supplements, most will be sourced from just beef and contain Type I & III.
A multi-collagen will offer all 5 types (I, II, III, V, & X) because it’s sourced from beef, chicken, fish, and eggshell membrane. There is much anecdotal data showing that humans benefit from multiple types of collagen. It is not scientifically proven.
Apart from the collagens that I mentioned above, Type I & III Collagen Peptides become the most popular collagen supplement in recent years.

What are Collagen Peptides?
Collagen Peptides are short chains of amino acids that are derived from collagen through a process called hydrolysis. This process breaks down collagen into smaller, more easily digestible molecules that can be absorbed and utilized by the body more efficiently.
Collagen vs Collagen Peptides: What are the Differences and Why Do They Matter?
One of the main differences between collagen and collagen peptides is their bioavailability or the extent to which they can be absorbed and utilized by the body. Collagen peptides are more easily absorbed and utilized than regular collagen, which means they may be more effective at delivering their health benefits.
What are the Benefits of Collagen Peptides?
Research has suggested that supplementing with collagen peptides may help to improve skin elasticity and hydration, reduce joint pain and stiffness, support bone health, and promote muscle mass and strength. Some studies have also suggested that collagen peptides may have anti-inflammatory and antioxidant properties, which could help to protect against oxidative stress and inflammation in the body.
Features of Collagen Peptides/Bioavailable Collagens/Hydrolyzed Collagens:
- Molecule Sizes Decreases - after hydrolysis, collagen peptides are 50 to 100 times smaller than an unhydrolyzed collagen molecule.
- Types - collagen peptides offer anywhere from one type (e.g. Type I) to five types (considered a multi collagen).
- Digestion - since peptides are already hydrolyzed, it will be digested slightly faster than regular collagen protein via foods.
- Bioavailability - even though peptides are broken down, they are still bioavailable, the ability of the substances to be absorbed or used by the body.
Now, we know the benefits of collagen peptides. It comes to questions - which collagen peptides I would recommend and how do we choose them?
How Do We Choose Collagen Supplement?
When choosing a collagen supplement, it's important to look for a high-quality product that contains collagen peptides, bioavailable collagens, or hydrolyzed collagens in Type I & III. These collagens are easily absorbed by the body, making them more effective.
It's also important to choose a collagen supplement that is derived from high-quality sources, such as grass-fed, pasture-raised cows, or wild-caught fish. These sources are typically higher in nutrients and lower in contaminants than conventionally-raised animals.
Based on these criteria, below are my top picks of the collagen peptides that you can easily find on Amazon:

If price is not a concern, you may consider Vital Proteins Collagen Peptides Powder and Vital Proteins Collagen Peptides Powder Chocolate as they are rated 4.6 ⭐️ with over 50,000 ratings! They also contain 20g of collagen peptides per serving.
Vital Proteins Collagen Powders also come in lemon, chocolate, and vanilla flavors. I bought the chocolate flavor and the review will be updated shortly 🤗
Meanwhile, NeoCell Super Collagen Powder 20g Collagen Peptides is also formulated with 20g of hydrolyzed collagen peptides per serving. It can provide some of the necessary building blocks to produce collagen and the price is a bit lower than Garden of Life and Vital Proteins so it's worth considering.

Alternatively, you may choose NeoCell Super Collagen Powder which is less expensive and has fewer calories than another powder form of collagens that mentioned above. However, it has only 10g of collagen peptides per serving.
What Form of Collagen Should We Take? Does Drinking Collagen Work?
Collagen supplements are available in different forms, including powders, tablets, and liquids. The form you choose will depend on your personal preferences. Collagen powder is the most popular form and is easy to mix into drinks or food. Collagen tablets are convenient for on-the-go use, while liquid collagen is ideal for those who prefer not to swallow pills.
As long as the supplements contain collagen peptides, bioavailable collagens, or hydrolyzed collagens, it doesn’t matter which form you take. However, we have to check the collagen peptides contained in the single serving in order to achieve the best skin care result.
In recent years, drinking collagen comes to light as an alternative to collagen powder so you may consider NeoCell Collagen Peptides + Vitamin C Liquid and Youtheory Collagen Liquid for Hair Skin and Nails with Collagen Peptides and Amino Acids as suggested in the above table. They are easy to consume, have fewer calories, and are less expensive. They contain Vitamin C and Amino Acids respectively which are also good for your skin.
There is another advantage for Youtheory Collagen Liquid - it is convenient to use and carry for travel.
Having said that, these drinking collagens contain fewer collagen peptides per serving.

How Much Collagen Peptides Per Day?
It is more important to check how much the collagen peptides contained in a single usage (you can take 2.5-20g safely). At the same time, follow the product instructions - most products recommend taking 1-2 scoops (10-20g) of collagen powder per day. You may want to speak with a healthcare professional before starting any new supplement regimen.
Some collagen supplements also contain Vitamin C or Hyaluronic Acid. So how do they work together with Collagen for your skin?
