Does collagen really work? An honest guide from Linverd

We see it every day: little tubs, gummies, collagen coffees, collagen crackers, “miracle” bone broths… and always the same question in the shop: “Does collagen really work or is it just marketing?”.

Here is how I explain it to Linverd customers: no smoke, no magic promises, and real examples you can apply in your daily life.

What collagen is and why everyone is talking about it

Collagen is the most abundant protein in your body. It gives structure to your skin, joints, tendons, ligaments, bones and even your gut. From around the age of 25–30, your body naturally produces less collagen, and that is when wrinkles, sagging, joint discomfort and slower recovery start to appear.

Is there a real problem here? Yes. Is there a magic solution in a jar? No. But when used properly, hydrolyzed collagen can help.

Collagen for skin: what you can realistically expect

The number one question: “Is collagen good for skin?”.

Most studies we have today say something quite reasonable: taking 2.5–10 g of hydrolyzed collagen per day for 8–12 weeks can moderately improve elasticity, hydration and the appearance of fine wrinkles. It is not an Instagram filter, but you do see a difference compared with taking nothing.

What does this mean in real life? – If you eat decently, sleep, don’t smoke and respect the sun, collagen can be a useful plus. – If your diet is a mess, your sleep is terrible and you live on ultra-processed foods, collagen will not “fix your face”.

Collagen and joints: knees, hips and all those clicks

The other big area where collagen makes sense is joint health. Many studies in people with knee pain or mild osteoarthritis show reduced pain and better function when they take collagen consistently.

What does that mean day to day? – Less pain when climbing stairs. – Easier training without the knee complaining so much. – Less stiffness first thing in the morning.

It is not an instant anti-inflammatory, but in the medium term it can make a real difference for people with worn cartilage or those who do a lot of impact sports.

Collagen for bones and muscle: when it makes sense

Collagen can also support bone health and muscle function, especially when combined with:

• Strength training (weights, bands, resistance work).
• A sufficient daily intake of total protein.
• Vitamin C and other micronutrients involved in collagen synthesis.

If you never train and eat very little protein, collagen on its own will not do much. But if you are an active person, especially after 35–40, it can be a useful tool to support joints, tendons and recovery.

What collagen does NOT do (despite the promises)

This is where marketing goes crazy. Collagen does NOT:

• Burn fat.
• Act like cosmetic surgery in a scoop.
• Replace the protein in your diet.
• Fix a poor diet and lifestyle on its own.

Your body does not take the collagen you drink and “paste” it directly onto your face or your knee. It breaks it down into amino acids and then builds what it needs. That is why context is key: diet, sleep, stress, exercise.

How to take collagen so it actually makes sense

If you decide to take collagen, do it with a clear strategy:

• Dosage: 5–10 g per day of hydrolyzed collagen is a solid reference range.
• Time: at least 2–3 months before judging results. This is not a 10-day challenge.
• Timing: whenever it best fits your routine. Many people take it at breakfast or in the evening.
• Vitamin C: supports collagen synthesis. Combine it with vitamin C–rich fruit or a supplement if needed.
• Quality: avoid products loaded with sugar, cheap sweeteners or artificial flavours. Fewer, clearer ingredients are usually better.

At Linverd we focus on three main ways of taking collagen:

• Organic bone broth: the most traditional, complete form, combining collagen, minerals and amino acids.
• High-quality collagen powder: easy to dose and mix with water, coffee or plant-based drinks.
• Functional snacks like our collagen crackers: perfect for people who want something practical, without refined sugar and with good raw materials.

Who benefits most from collagen

From what I see every day in the shop, collagen makes the most sense for:

• People with mild to moderate joint pain, especially knees and hips.
• Women over 35–40 who care about skin, joints and maintaining muscle mass.
• Impact athletes (running, crossfit, padel, etc.) who want to care for tendons and recovery.
• People who almost never eat offal, bone broth or gelatinous cuts of meat.

Where does it make less sense?

• If your top priority should be to improve basic nutrition first (ultra-processed foods, sugar, daily alcohol…).
• If you expect a “miracle” in two weeks.

So… does collagen work?

Short answer: yes, collagen works, but:

• Its effect is moderate, not magical.
• It depends on consistency and your overall lifestyle context.
• It makes far more sense if you also improve your diet, do strength training and sleep reasonably well.

At Linverd we are not here to sell you yet another “miracle powder”. What we do is help you choose the type of collagen that makes the most sense for you – bone broth, powder supplement or enriched foods like our crackers – and show you how to integrate it into your routine so it actually adds value.
