Collagen is one of those supplements whose effects I could clearly see and feel in my own skin. Once I started taking it regularly, my skin became more hydrated and fine lines became less noticeable. In this article, I explain why collagen peptides decline with age, what collagen does in your body and how to choose a supplement that actually works.
Why collagen declines with age
Hydrolyzed collagen is a protein that keeps your skin firm, your joints mobile and your tendons strong. When you are young, your body produces enough on its own. But from around the age of 25, your body starts losing approximately 1.5% of its collagen stores each year. That may not sound like much, but the years quickly add up.
By the time you reach 35, your body contains about 15% less collagen than it did at twenty. By 45, the difference is approximately 30%. That is why, around your forties, your skin starts to feel thinner and drier, and wrinkles appear where there were none before.
Honestly, I did not notice it myself for a long time. The first sign was that dry winter air started affecting my skin more than it used to. The heating had not changed, and I was using the same skincare products — only my skin was different.
How collagen affects your skin
Collagen makes up about 70% of your skin by dry weight. This protein provides the foundation for elasticity, firmness and hydration. As collagen levels decline, your skin starts to sag, loses its glow and develops deeper wrinkles.
Taking collagen as a supplement does not magically make your body produce new protein. It does, however, provide amino acids — primarily glycine, proline and hydroxyproline — that your body uses to synthesize its own collagen. Its effectiveness depends on the dose, how consistently you take it and how well your chosen product is absorbed.
Here is what I noticed myself after two to three months:
- My skin feels softer and more hydrated to the touch
- The fine lines around my eyes have become less pronounced
- My hair and nails grow more vigorously
- Cravings for sweets are easier to manage while on a diet (especially with flavored varieties)
How to choose a good collagen supplement
There are dozens of collagen supplements on store shelves — powders, capsules, drinks and chewable tablets. Some are excellent; others are simply expensive. Here are a few things I look for when choosing one:
- Hydrolyzed collagen peptides, also known as collagen peptides — the molecules have been broken down into pieces small enough for your body to absorb
- Dose — studies typically use 5–10 g per day. If a tablet contains less than 2.5 g, you need to take several at once
- Vitamin C in the formula or taken alongside it — your body needs it to synthesize collagen
- Taste and form — the best supplement is the one you actually take every day
I have tried various options, and my clear favorite so far is Olimp Kolagen Activ lemon-flavored chewable tablets. They are easy to dose, taste good and ease cravings for sweets while on a diet. Since taking them regularly, I have noticed both improved skin hydration and a reduction in wrinkle depth.
Practical tips for taking collagen
A supplement alone will not work miracles. Here are a few things that genuinely help collagen work:
- Drink enough water each day — collagen will not hydrate dry skin if your body is dehydrated
- Eat protein with every meal (meat, fish, eggs, cottage cheese) — hydrolyzed collagen needs amino acids as its raw materials
- Sleep for at least 7 hours a night — your body produces more collagen during deep sleep
- Protect your skin from the sun — UV rays break down collagen faster than any supplement can replace it
- Cut down on sugar — sugar binds to collagen fibers and makes them brittle (glycation)
The simple truth is that a collagen supplement delivers results after about eight weeks of regular use. Nothing dramatic happens in the first couple of weeks — it is not a cream, but a process that takes longer.
Frequently asked questions about collagen
When should you start taking collagen?
Since your body starts losing collagen at around 25, that is a sensible age to consider starting. Starting later is just as good — taking it regularly also produces visible results at 40 and 50.
Can you take collagen every day long term?
Yes. Collagen peptides are a component of food, and your body recognizes their amino acids just as it does those in protein from meat or fish. There is no need to take breaks, but you should make sure your daily dose stays within the manufacturer’s recommended limits.
Does collagen help your joints too?
Joint cartilage is largely made of collagen. Athletes and runners take collagen for this very reason. The effects are not as quickly apparent as they are in the skin, but taking it over a longer period may reduce joint stiffness and creaking.
