Collagen is a structural protein found in the body that helps make up our connective tissue, skin, hair, nails, tendons, bone, and cartilage. Considering that it's the most abundant protein in the body, there's no question that collagen plays an incredibly important role in our health and well-being.
For athletes, collagen serves as a key protein during recovery from exercise. Fun fact, as we age, our collagen production and stores decrease which results in aging of the skin. Considering collagen's integral part of maintaining our body's structure, some people choose to supplement with it to boost their body's stores and internal production.

While not a true collagen peptide supplement, these products contain ingredients known to support healthy collagen production. At the top of our list for the best collagen-boosting supplement for skin is Ora Aloe Gorgeous mainly due to their comprehensive and transparent active ingredient list.
This powder contains a blend of organic pea protein, organic acerola cherry extract, organic aloe vera gel powder, organic bamboo extract, and vitamin E from sunflower.

Typically, collagen supplements come in a powder form and are meant to be mixed with your beverage of choice. That being said, not everyone enjoys the flavor that collagen supplements may impart in their drinks.

When it came to choosing the best collagen capsules, we found Vital Protein's Collagen Peptides Capsules to be the top option on the market.
While the six capsule serving size only provides 3.3 grams of hydrolyzed bovine peptides, some studies have shown that doses as low as 2.5 grams may still have a beneficial effect on joints, skin, nails, and hair.(12) If you wanted to take an additional serving to increase this amount it would generally be safe for most people considering many powders provide upward of 15 grams per serving.

That said, with advances in technology in recent years there is a new kid on the block in terms of collagen sourcing, eggshell membranes. These are the membranes that line bird eggs, which are particularly high in type I, V, and X collagen. Considering that eggshells are considered vegetarian, this makes a great option for vegetarians looking to take a powdered collagen supplement.

How We Chose the Best Collagen Supplements
When analyzing the top products on the market there were several factors we took into consideration to give you the best collagen supplements.
Type
There are five types of collagen found throughout the body, each of which have different functions. While most of the products we reviewed contain type I & III, we were also sure to include a few that included other types as well.
Source
While bovine is the most common source of collagen, several others are also found in collagen supplements such as chicken, fish, and eggshell. We made sure to include collagen supplements from a number of sources to suit the needs of all users.
Form
Generally speaking, collagen supplements are most often found in powder form due to their wide availability and cost. We sought out a variety of collagen forms including powder, liquid, and capsule.
Dosage
Most research suggests a dose of five to 15 grams is sufficient for most populations. (1) Therefore, the majority of the products we selected fall within that range.
Price
When it comes to collagen supplements, costs can vary widely depending on the type, source, flavoring, and a number of other factors. Most basic collagen supplements will fall within the $0.50-$1.00 per serving range. We explored a wide price range though settled on products that most users could easily fit in their budgets.
How to Choose the Best Collagen Supplements
When setting out to find the perfect collagen supplement to meet your goals there are several important factors to keep in mind.
Types of Collagen
There are five types of collagen commonly found throughout the body. These include:
- Type I: The most common type of collagen making up 90-percent of our body's collagen. It's found in our skin, bones, joints, cartilage, and teeth.
- Type II: This is the major type of collagen found in cartilage, a connective tissue that protects the end of our long bones and helps form joints.
- Type III: The second most common type of collagen found in our bodies, type III collagen is a major component of our skin and organs. It's often found in many of the same places where type I collagen is found.
- Type V: This type of collagen is found in smaller amounts in the body and serves as a structural support to the other types of collagen, most commonly type II. It also helps form our skin and hair.
- Type X: Type X collagen is another structural support compound helping to support other types of collagen to form our bones and joints. It also provides structure for our hair and may reduce hair breakage when supplemented.
In general, most supplements will contain types I and III as the other types are slightly harder to come by in supplement form and may be more expensive. Types I and III will suit most people's needs for general joint, gut, hair, skin, and nail health.
Source
Collagen supplements found on the market will usually some from the following sources:
- Bovine (cow): By far the most common source of collagen protein. Contains types I and III. Sourced from cow hides.
- Chicken: Not as commonly used in supplements. Contains mainly type II collagen. Sourced from chicken cartilage.
- Marine: Several brands offer a marine collagen option that is usually sourced from fish scales. Contains type I and III in a similar composition to bovine collagen.
- Eggshell membrane: Commonly used in vegetarian collagen supplements. Contains type I, V, and X collagen.
Unfortunately at this time, vegan collagen supplements are not readily available due to their expensive production process. That said, there are many vegan collagen-boosting supplements that are meant to improve your body's own natural collagen production.
Flavor
Generally speaking, pure unflavored collagen powder is rather flavorless, making it a great option to add to other beverages as it doesn't impart much taste. For this reason many brands sell unflavored collagen powders that can be added to hot or cold drinks of your choice. Some companies also sell flavored varieties that are mixable with water. Consider if you'd prefer a flavored or unflavored option when shopping for a collagen supplement.
FAQs About Collagen Powders
How Much Collagen is a Healthy Amount?
For general purposes such as supporting joint, gut, skin, nail, and hair health the research suggests taking a five to 15 gram dose of collagen peptides will provide the best results for most people. (1) Most collagen supplements fall within this range. Taking more than this would not likely be harmful, though it may be a waste.
What form of collagen is most effective?
There is no one form of collagen that is necessarily better than others though collagen supplements coming from animal sources, such as bovine, chicken, and marine, are best able to be utilized by our bodies. You will find that most collagen supplements contain one of these sources, thus you won't have to worry much about what form is best. That said, be sure to look for a collagen supplement that is hydrolyzed, which means it is broken down further, as this can enhance absorption.
Do I need all 5 types of collagen?
Our bodies are able to synthesize collagen from other protein-containing foods that we eat therefore it's not necessary to take a supplement that includes all five types. Most supplements include types I and III, which are suitable options for supporting bone, joint, hair, skin, and nail health.
How fast does collagen start working?
Considering that collagen turnover is a slow process, most people will have to wait at least four to eight weeks to start seeing results, and in some cases even longer.(13, 14) Those looking for improvements in hair, skin, and nail health may see quicker results, whereas those taking collagen for bone and joint health may have to wait a bit longer.
Are there any negative effects of taking collagen?
In general, most people will not experience any side effects when supplementing with collagen. That being said, if you have a known allergy it's imperative that you check the label to make sure it doesn't contain an ingredient you're allergic to. Some people may experience mild digestive distress or a bad taste in their mouth when supplementing with collagen. It's always important to check with your healthcare provider before starting any new supplements if you have a pre-existing condition.
