Drug Information


How to take collagen has become an essential topic in the health and wellness industry, with collagen supplements gaining popularity for their potential benefits in skin health, joint support, and overall well-being. As the most abundant protein in our bodies, collagen plays a crucial role in maintaining the structure and function of our skin, bones, muscles, and connective tissues. However, as we age, our natural collagen production decreases, leading many to turn to collagen supplements to help maintain their youthful appearance and support their body’s various systems.

In this comprehensive guide, we’ll delve into the world of collagen supplementation, covering everything from what collagen is and its various benefits to how to take it effectively in different forms. Whether you’re new to collagen supplements or looking to optimize your current regimen, this article will equip you with the knowledge to make informed decisions about your collagen intake.

What is Collagen?

Collagen is a protein that serves as a major building block in our bodies. It’s found abundantly in our skin, bones, muscles, tendons, and ligaments, providing structure, strength, and elasticity to these tissues. Think of collagen as the “glue” that holds our bodies together, offering support and resilience to various bodily structures.

There are at least 28 types of collagen identified in the human body, but types I, II, and III are the most common:

  • Type I: The most abundant, found in skin, bones, and connective tissues. It provides structure to skin, bones, fibrous cartilage, teeth, tendons, and ligaments.
  • Type II: Mainly found in elastic cartilage, providing cushioning to joints.
  • Type III: Present in skin, muscles, and blood vessels. It’s often found alongside Type I collagen and is important for skin elasticity and firmness.

As we age, our bodies naturally produce less collagen, leading to common signs of aging like wrinkles, joint pain, and decreased bone density. This natural decline has sparked interest in collagen supplementation as a way to support overall health and combat these age-related changes.

Forms and Types of Collagen Supplements

Collagen supplements come in various forms to suit different preferences and needs:

  1. Powder: The most versatile form, easily mixed into drinks or foods. It’s virtually tasteless and can be incorporated into a variety of recipes.
  2. Capsules: Convenient for those who prefer a quick, tasteless option. Ideal for people on the go or those who don’t want to mix powders.
  3. Liquid: Pre-mixed for easy consumption, often flavored. This form is ready to drink and can be a good option for those who struggle with pills or powders.
  4. Gummies: A tasty alternative that’s easy to consume, though they may contain added sugars.

When choosing a collagen supplement, you’ll also encounter different types based on their source:

  • Bovine collagen: Derived from cows, typically types I and III. It’s the most common and widely studied form.
  • Marine collagen: From fish, usually type I. It’s known for its high bioavailability.
  • Chicken collagen: Primarily type II, often used for joint health.
  • Egg membrane collagen: Contains types I, V, and X.
  • Porcine collagen: From pigs, similar to bovine collagen.

Benefits of Collagen Supplementation

Collagen supplementation has been associated with numerous health benefits, supported by a growing body of scientific research. Let’s explore some of the key areas where collagen may make a difference:

Skin Health

Collagen is a crucial component of our skin, providing structure and elasticity. As we age and our natural collagen production decreases, we may notice increased wrinkles and decreased skin hydration. Several studies have shown that collagen supplementation can improve skin elasticity, hydration, and reduce the appearance of wrinkles.

A 2019 review of 11 studies found that oral collagen supplementation increased skin elasticity, hydration, and dermal collagen density. Participants typically took between 2.5 to 10 grams of collagen per day for 8-24 weeks.

Joint Support

Collagen plays a vital role in maintaining healthy joints by providing structure to our cartilage. As we age, the breakdown of collagen can lead to joint pain and conditions like osteoarthritis. Collagen supplementation, particularly type II collagen, has shown promise in supporting joint health.

A 2019 study found that athletes who consumed 10 grams of collagen daily for 24 weeks experienced a significant decrease in joint pain compared to a placebo group. Another study showed that adults with osteoarthritis who took 40 mg of undenatured type II collagen daily for 180 days had significant improvements in joint function and pain reduction.

Bone Strength

Collagen is a major component of our bones, providing them with structure and strength. As we age and lose collagen, our bones can become more fragile, increasing the risk of osteoporosis. Some studies suggest that collagen supplementation may help support bone health.

A 12-month study of postmenopausal women found that those who took 5 grams of collagen peptides daily had significantly increased bone mineral density compared to the control group. This suggests that collagen supplementation could be a valuable strategy for maintaining bone health as we age.

Hair and Nail Growth

While more research is needed in this area, some studies and anecdotal evidence suggest that collagen supplementation may support hair and nail health. Collagen contains amino acids that are essential for keratin production, the protein that makes up our hair and nails.

A 2017 study found that women who took 2.5 grams of collagen daily for 24 weeks experienced improved nail growth and decreased brittleness. While direct studies on hair growth are limited, the role of collagen in providing amino acids for keratin production suggests it could support hair health as well.

Gut Health

Emerging research suggests that collagen may play a role in supporting gut health. The amino acids in collagen, particularly glycine and glutamine, may help support the integrity of the intestinal lining.

While more human studies are needed, animal studies have shown promising results. For example, a 2017 study on mice found that collagen peptides helped reduce inflammation and protect against leaky gut syndrome.

How to Take Collagen in Different Forms

Now that we’ve explored the benefits of collagen, let’s discuss how to take it effectively in its various forms:


Collagen powder is perhaps the most versatile form of supplementation. Here’s how to use it effectively:

  • Dosage recommendations: Most studies showing benefits used between 2.5 to 15 grams per day. Start with a lower dose and gradually increase if needed.
  • How to mix and consume: Collagen powder can be mixed into hot or cold liquids. It dissolves best in hot liquids but can also be blended into smoothies, mixed into yogurt, or even baked into foods. Unflavored varieties can be added to coffee or tea without altering the taste significantly.
  • Best times to take: There’s no definitive best time to take collagen. Some prefer morning to support all-day benefits, while others take it before bed to support overnight repair processes. Consistency is more important than timing.


Collagen capsules offer a convenient, tasteless option for supplementation:

  • Typical dosage: Capsules typically contain between 500mg to 1500mg of collagen. Follow the manufacturer’s recommendations, but most suggest taking 2-6 capsules daily.
  • Administration tips: Take capsules with a full glass of water. If the capsules are large, you may split the dose throughout the day for easier consumption.
  • Timing considerations: As with powder, consistency is key. Some people prefer to take capsules with meals to aid absorption, but this isn’t strictly necessary.


Liquid collagen offers a pre-mixed, often flavored option:

  • Recommended serving sizes: Follow the manufacturer’s guidelines, as concentration can vary widely between products. Typical servings range from 15-30 mL daily.
  • How to incorporate into diet: Liquid collagen can be consumed directly or mixed into other beverages. Some people enjoy adding it to their morning smoothie or drinking it as part of their bedtime routine.
  • Optimal consumption times: As with other forms, there’s no definitive best time. Choose a time that works consistently with your schedule.

Best Practices for Taking Collagen

To get the most out of your collagen supplementation, consider these best practices:
