Collagen is one of the most talked-about ingredients in wellness today, appearing in everything from protein powders to beauty products and healthy aging routines. As interest has grown, so has the number of collagen supplements available, making it difficult to understand which options may be worth considering.
One of the most common questions is: What are collagen peptides, and how are they different from other forms of collagen? You may also see terms like hydrolyzed collagen or collagen hydrolysate, which often leads to even more confusion.
Understanding how collagen peptides are made, how they’re used and the potential collagen peptides benefits can make it easier to choose a supplement that fits your needs. One important consideration is whether the collagen has been hydrolyzed, a process that helps make it easier for the body to absorb.
This guide explains what collagen peptides are, explores their potential benefits, discusses how to use them, reviews the types of supplements available and answers frequently asked questions.
What are collagen peptides?
Collagen is the body’s most abundant protein and serves as a key structural component of connective tissues. It’s naturally found throughout the skin, joints and more, where it helps provide structure and support to these tissues.
Beyond its structural role, collagen also helps support healthy skin, hair, nails, joints and gut health as part of an overall healthy lifestyle.
Collagen peptides are small protein fragments created from animal-derived collagen. They’re also commonly referred to as hydrolyzed collagen or collagen hydrolysate because they undergo a process called hydrolysis, which breaks larger collagen proteins into smaller peptides.
Collagen peptide supplements are commonly sourced from ingredients such as:
- Bovine collagen
- Chicken collagen
- Fish (marine) collagen
- Eggshell membrane collagen
Although your body naturally produces collagen, production gradually declines with age. Everyday lifestyle factors, including smoking, excessive sun exposure and an overall poor-quality diet, may also influence the body’s collagen levels.
Because collagen is made from amino acids, collagen peptide supplements provide the building blocks your body uses to produce and maintain its own collagen. When paired with a balanced diet and healthy lifestyle, they can be a convenient way to increase collagen intake.
Since collagen peptides have already been hydrolyzed, they’re generally easy to absorb, allowing those amino acids to become available for normal collagen production throughout the body.
Collagen peptides benefits
Collagen peptides supply amino acids that support many of the body’s connective tissues. Potential collagen peptides benefits include supporting gut health, joint function, healthy skin and exercise recovery when used consistently as part of an overall healthy lifestyle.
1. Help support healthy joints and mobility
Collagen plays an important role in maintaining connective tissues, including cartilage. Because this tissue relies on collagen for their structure, adequate collagen intake may help support normal joint function and mobility.
In fact, clinical research on specific high-quality collagen peptides has shown they may:
- Reduce joint stiffness as early as seven days
- Â Promotes joint mobility
- Improves joint comfort beginning as early as 30 days
- Helps protect cartilage and reduce post-exercise joint discomfort and stiffness
2. Support healthy skin, hair and nails
Collagen is one of the primary proteins found in skin and is also present in healthy hair and nails. Regular collagen supplementation may support a healthy beauty routine by helping maintain normal skin elasticity and hydration while supporting healthy-looking hair and nails.
Clinical studies evaluating specific collagen supplements have also found they may:
- Promotes skin firmness and elasticity in the crow’s feet area after 42 days
- Improves skin texture after six weeks
- Support healthy hair
- Promote youthful skin appearance
- Support skin hydration around the eyes
- Support healthy nails
(Note: As with all supplement research, these outcomes are associated with specific studied ingredients.)
3. Support gut health
Collagen formulated with a probiotic also contributes to overall gut health and function.
Maintaining a nutrient-rich diet and healthy lifestyle remains the foundation of digestive wellness, with collagen serving as one component of that overall approach.
4. Support exercise recovery
Collagen supplementation may also be beneficial for physically active individuals.
Clinical research evaluating specific collagen peptides have also found they may:
- Provide rapid relief from exercise-related joint discomfort and stiffness, meaning in as early as 10 days
- Improves joint flexibility beginning as early as 30 days
- Helps protect cartilage and reduce post-exercise joint discomfort and stiffness
- Improves joint comfort as early as 30 days
How to use collagen peptides
One of the reasons collagen peptides have become so popular is their versatility. They can be incorporated into a daily routine in several ways and are generally easy to mix into foods and beverages because hydrolyzed collagen dissolves readily.
How much collagen should you take?
The ideal daily amount depends on your individual wellness goals.
- Around 10 grams per day is a commonly recommended serving for most adults seeking general collagen support. This amount can be taken all at once or divided into two servings throughout the day.
- Approximately three to five grams daily may help support healthy skin.
- Approximately 20 to 30 grams daily may be more appropriate for individuals looking to support joint health.
- For fermented eggshell membrane collagen capsules, as little as 500 milligrams per day may provide benefits, depending on the formulation.
Consistency is important. Taking collagen peptides every day as part of an overall healthy lifestyle may help you maximize their potential benefits over time.
When should you take collagen peptides?
Collagen peptides can be taken any time of day, with or without food, making them easy to incorporate into an existing routine.
Unflavored collagen powders blend well into both hot and cold foods and beverages without significantly changing taste or texture. Popular ways to use collagen peptides include adding them to:
- Coffee
- Oatmeal
- Smoothies and shakes
- Pancake batter
- Muffin batter
- Other baked goods and recipes
For the greatest overall benefit, combine collagen supplementation with a nutrient-dense eating pattern that includes foods rich in nutrients involved in normal collagen production, including vitamin C, copper, manganese and antioxidant-containing fruits and vegetables.
Collagen peptide supplements
Because it can be difficult to obtain larger amounts of collagen through food alone, many people choose collagen peptide supplements as a convenient way to increase their intake.
Collagen peptides are available in several formats, allowing you to choose the option that best fits your preferences and lifestyle.
Common forms include:
- Hydrolyzed collagen powder
- Collagen capsules
- Tablets
- Gummies
When comparing collagen supplements, there are several factors worth considering.
Look for hydrolyzed collagen
Hydrolyzed collagen has already been broken down into smaller peptides, making it generally easier for the body to absorb than non-hydrolyzed collagen proteins.
Consider collagen sources
Many collagen supplements combine multiple food-based collagen sources, which may include:
- Bovine collagen
- Chicken collagen
- Marine (fish) collagen
- Eggshell membrane collagen
Different products may contain one source or a blend of several sources.
Check the ingredient list
Some collagen supplements also include complementary ingredients such as:
- Vitamin C
- Probiotics
- Additional nutrients intended to complement a healthy lifestyle
Reading the ingredient label carefully can help you select a formula that aligns with your individual preferences and wellness goals. (Good options include Ancient Nutrition’s Multi Collagen Protein, Multi Collagen Advanced and Collagen Peptides Protein.)
Precautions
For most healthy adults, collagen peptide supplements are generally considered safe and are well tolerated when used as directed.
Many collagen products are free of gluten and may also be formulated without dairy, soy, nuts or artificial sweeteners, making them suitable for a variety of dietary preferences. Even so, ingredient lists vary between brands, so it’s always important to review the label before purchasing a supplement.
Choosing a high-quality collagen supplement is another important consideration. Look for products made by reputable manufacturers that use high-quality ingredients and avoid unnecessary fillers, antibiotics and artificial ingredients whenever possible
As with any dietary supplement, speak with your healthcare provider before adding collagen peptides to your routine, especially if you take prescription medications or have questions about whether supplementation is appropriate for your individual needs.
