Collagen is not a passing hype, but an enduring trend firmly rooted in scientific research. Its popularity comes from proven benefits for skin, joints and bones, combined with the natural decline in collagen production from the age of 25. With realistic expectations and the right type of supplement, you can actually benefit from collagen supplementation.
What exactly is collagen and why has it become so popular?
Collagen is the most abundant protein in your body and forms the basis of your skin, bones, joints, blood vessels and muscles. It provides strength, elasticity and structure to your tissues. Your body makes this protein itself, but that production decreases by about 1-2% annually from the age of 25.
The popularity of collagen supplement has grown tremendously in recent years as people notice the effects of this natural decline. Wrinkles, stiffer joints and less firm skin are all signs that your collagen supply is dwindling. At the same time, more and more research has become available confirming the benefits of collagen supplementation.
Social media and influencers have also played a role in its popularity. Many people share their positive experiences with collagen products, especially in terms of skin improvement. These visible results make it attractive for others to try it too.
What benefits of collagen have been scientifically proven?
Research shows that collagen supplementation actually has benefits for various aspects of your health. The most convincing results are seen in skin health, joint function and bone density. Studies show that regular use can lead to more skin elasticity and fewer wrinkles.
For your joints, the evidence is also strong. Several studies show that collagen supplement use can help with joint pain and stiffness, especially in people with osteoarthritis. It seems to stimulate cartilage production and reduce inflammation.
In terms of muscle growth and recovery, the results are less pronounced but positive. Collagen contains amino acids important for muscle tissue, although it is not as complete as other protein sources.
Beware of exaggerated claims, though. Collagen is not a panacea that stops all signs of ageing. The effects are gradual and work best as part of a healthy lifestyle with adequate sleep, good nutrition and exercise.
How to choose the right type of collagen for your goals?
There are different types of collagen, with Type I, II and III being the most relevant for supplements. Type I is best for skin, hair and nails, Type II targets joints and cartilage, and Type III supports blood vessels and muscles. Many supplements combine these types for broader benefits.
The form in which you take collagen also matters. Powder dissolves easily in drinks and is well absorbed by your body. Capsules are convenient if you don't like the taste. Drinks are practical but often more expensive and sometimes contain unnecessary additives.
When choosing, look at the source of the collagen. Beef and fish are the most common sources, with fish collagen being slightly better absorbed. Also check if the product is hydrolysed - this means the collagen has been broken down into smaller pieces that your body can use more easily.
Dosage is also important. Most studies use between 2.5 and 10 grams per day. Start with a lower dose to see how your body reacts, and gradually increase as needed.
What are the realistic expectations when using collagen?
Don't expect miracles within a few weeks. Most people notice the first effects after 4-8 weeks of regular use, with skin improvement often noticed first. For joints, it can take 8-12 weeks before you notice clear improvement.
Realistic effects are subtle but noticeable. Your skin may feel smoother, small wrinkles may become less visible and your joints may feel less stiff. Don't expect dramatic anti-ageing effects or complete relief from joint problems.
For optimal results, it is best to take collagen on an empty stomach, for example in your coffee or smoothie in the morning. Combine it with vitamin C, as this supports collagen production in your body. Regularity is more important than exact timing.
Remember that collagen works best as a complement to a healthy lifestyle. Get enough sleep, drink enough water, eat a varied diet and protect your skin from the sun. These factors have at least as much impact on your skin and joints as supplements.

Frequently Asked Questions
Can I combine collagen with other supplements I am already taking?
Yes, collagen can be safely combined with most other supplements. It even works better together with vitamin C, zinc and hyaluronic acid. Avoid taking it together with calcium or magnesium, though, as this can reduce absorption. Preferably take collagen 30 minutes before or after other supplements.
Why am I not seeing results after 6 weeks of collagen use?
This can have several causes: too low a dosage (try 5-10 grams per day), poor quality of the product, or interference with other factors such as stress, lack of sleep or an unhealthy lifestyle. Also check if you take collagen on an empty stomach for better absorption.
Is there a difference between animal and plant collagen?
Echt plantaardig collageen bestaat niet – planten maken geen collageen aan. ‘Plantaardige collageen’ producten bevatten meestal aminozuren en vitamines die de natuurlijke collageenproductie ondersteunen. Voor directe collageeninname heb je dierlijke bronnen (rund, vis, kip) nodig, waarbij viscollageen het beste wordt opgenomen.
Can I take too much collagen and are there any side effects?
Collagen is generally safe, but doses above 20 grams per day can cause stomach upset, nausea or feeling full. Most people have no side effects at 5-10 grams per day. People with food allergies to fish or beef should be careful about the source of their collagen.
Should I stop taking collagen if I am pregnant or breastfeeding?
Although collagen is a natural protein, there is insufficient research on safety during pregnancy and lactation. Always consult your doctor before using collagen supplements during this period. During pregnancy, focus on a high-protein diet for natural collagen production.
What is the best way to store collagen and how long does it last?
Store collagen powder in a cool, dry place in a tightly sealed container. Avoid direct sunlight and moisture. Most products last 2-3 years if stored properly. Always check the expiry date and watch for changes in smell, colour or texture.
Can I use collagen if I follow a specific diet such as keto or vegan?
Collagen fits well with a keto diet because it is pure protein with no carbohydrates. For vegans, traditional collagen is not suitable because it comes from animals. Vegans are better off choosing supplements with vitamin C, lysine and proline to boost natural collagen production.
