Understanding Collagen
Collagen is an important protein. It acts like the “glue” that holds the body together. It is found in skin, bones, tendons, and connective tissues, providing support, strength, and elasticity.
Type I collagen, the most prevalent, is present in skin and bones. As we age, collagen production decreases, resulting in wrinkles and reduced skin elasticity. Additionally, collagen aids in wound healing, bone regeneration, joint health, and dental health.
Are Collagen Supplements Worth It?
To answer that question, let’s consider what clinical studies have found. If you prefer a more visual explanation, refer to the video below. Collagen supplements help the body by providing the building blocks, called amino acids, and bioactive peptides.
These components enter the bloodstream, where the body can utilize them to create new collagen.
- Amino acids are the basic materials.
- Bioactive peptides signal fibroblast cells in the skin to increase collagen production. These peptides also stimulate the production of other important molecules, like hyaluronic acid, which helps with skin hydration. If you want to learn more about the science behind bioactive peptides and it’s benefits read our dedicted article.
The molecular weight of collagen supplements is important because smaller molecules are generally easier for the body to absorb. Hydrolyzed collagen usually has molecular weights between 2,000 Da and 5,000 Da. Researchers often find that lower molecular weights are absorbed more easily.

What to Expect: Timeline for Noticeable Changes
A meta-analysis of 26 studies found oral hydrolyzed collagen supplementation significantly enhances skin hydration and elasticity (link to the studies is in the References section).
Studies show that the time collagen supplements take to work and show visible results is between 4 to 12 weeks of consistent use. These improvements occur over three stages
- 2 to 4 weeks: Some may notice slight increases in skin hydration.
- 4 to 8 weeks: Skin elasticity improves, with notable hydration changes between weeks 4 and 6.
- 8+ weeks: Significant improvements in hydration and elasticity become apparent. Continued use enhances these effects further.
Studies emphasize that hydrolyzed collagen’s benefits become more pronounced after 8 weeks, highlighting the importance of consistency.
Individual results can vary due to factors like the type of collagen used, dosage, and frequency of intake.

Recommended Duration for Collagen Supplement Use
Collagen supplementation is much like tending to a garden—consistent care and patience yield the best results.
To see real benefits from collagen supplements, it’s best to use them regularly for 3 to 6 months. While some people may notice better skin health and well-being within 4 to 12 weeks, long-term use improves these effects significantly.
How Much Collagen Should You Take?
The recommended daily dosage typically ranges from 2.5 grams to 10 grams of collagen. For more significant improvements in skin hydration or elasticity, consider a dose at the higher end of the range.
How to Take Collagen Powder?
- Mix it into water, smoothies, yogurt, beverages or soups.
- Aim for a daily dosage of 5,000 to 10,000 mg.
- Maintain regular intake for at least 3 to 6 months to see noticeable results.

Factors Influencing Collagen Supplements Effectiveness
Individual results from collagen supplements can vary significantly. Factors could include the type of collagen used, the dosage, and the duration of use. Additionally, lifestyle and nutritional choices can impact results.
How Can You Make Collagen Work Faster?
Lifestyle Choices
- Smoking and excessive alcohol consumption significantly hinder collagen production.
- Smoking introduces harmful toxins that reduce blood flow and nutrient delivery to the skin, diminishing collagen synthesis.
- Alcohol dehydrates the skin and disrupts nutrient absorption, further impeding collagen’s ability to maintain skin elasticity and hydration.
UV Radiation
- Sun exposure breaks down collagen fibers and lowers skin quality, accelerating aging signs like wrinkles and fine lines. Thus, protecting your skin while using collagen supplements is essential. To combat UV effects, adopt effective sun protection habits. Use broad-spectrum sunscreen with high SPF, wear protective clothing, and seek shade during peak sun hours.
Nutrients That Support Collagen Production
- Collagen synthesis requires several essential vitamins and nutrients that play crucial roles in promoting healthy skin and struture.
- Vitamin C stabilizes collagen fibers.
- Minerals like zinc, iron, and copper are essential for enzymatic processes in collagen production.
- Antioxidants from fruits, vegetables, and nuts help neutralize UV-induced free radicals.
- Biochemical Response: When you're stressed, your body releases cortisol, a stress hormone that can lead to reduced microbial diversity and an overgrowth of harmful bacteria like Proteobacteria. This imbalance can contribute to inflammatory skin conditions.
- Physical Response: Stress weakens the gut barrier by affecting the tight junctions between epithelial cells, allowing toxins, bacteria, and partially digested food particles to pass into the bloodstream, triggering an immune response. This inflammatory reaction can further disrupt gut balance and has been linked to anxiety and depression. Stress management techniques such as meditation, yoga, and deep breathing stimulate the vagus nerve, which helps restore the balance of gut bacteria and lowers inflammation.
Long-Term Benefits and Impact on Overall Health
Beyond improving skin, research shows that collagen is essential for healthy hair, gut health, and overall well-being. It supports the gut lining by providing amino acids needed to repair and strengthen intestinal walls.
Collagen supplements also aid joint health, reducing joint pain and improving movement by promoting cartilage growth and better joint function.
Studies suggest that adding collagen peptides to your diet may enhance bone health, especially for those at risk of osteoporosis or age-related bone loss.

FAQs
Generally, the form of collagen supplement (powder, pills, liquid) has a minimal impact on how quickly it works, as long as the dosage and bioavailability are comparable. The key factor is how well the collagen has been hydrolyzed (broken down into smaller peptides) for absorption, regardless of the delivery method. Powders are often easier to consume in larger doses, which might lead to perceived faster results for some, but well-formulated pills and liquids can be equally effective if the peptide size and dosage are optimized for absorption.
The first signs that a collagen supplement might be working can vary from person to person. Some individuals report experiencing improved skin hydration within the first few weeks, noticing their skin feels less dry and more supple. Others might observe subtle improvements in nail strength, with less breakage. For joint comfort and other benefits related to deeper tissues, it often takes longer to notice significant changes.
To maximise the effectiveness of collagen supplements, it's advisable to avoid or minimize factors known to hinder natural collagen production and damage existing collagen. These include:
- Smoking: Significantly impairs collagen synthesis.
- Excessive Alcohol Consumption: Dehydrates the skin and can disrupt nutrient absorption.
- Excessive UV Radiation (Sun Exposure): Breaks down collagen fibers. It's crucial to use sun protection.
- High Sugar and Processed Food Intake: Can contribute to inflammation and glycation, damaging collagen.
- Nutrient Deficiencies: Ensure you have adequate intake of Vitamin C, zinc, and copper, which are essential for collagen production.
Yes, there are different types of collagen, with Type I, II, and III being the most common in supplements. Type I is the most abundant in the body and is excellent for skin, hair, nails, bones, and tendons. Type III often works alongside Type I and is also beneficial for skin elasticity and gut health. Type II is primarily found in cartilage and is often used to support joint health. The "best" type depends on your specific health goals. Many supplements, particularly bovine collagen, contain a blend of Type I and III, offering broad benefits.
