One of the most common questions we're asked about collagen supplementation is "How long does collagen take to work?"
The short answer is simple: collagen isn't an overnight fix.
Like any nutritional change or wellness habit, consistency is key and there is no quick fix.
Are collagen supplements really necessary?
Yes. As your body naturally produces less collagen with age, supplementing with high-quality collagen peptides can help support healthy skin, joints, hair, nails and overall wellness over time.
Getting collagen peptides from supplements can help to bridge the nutritional gap between diet and requirements, mitigating the effects of depleting collagen stores as we get older - but quality is key.
At Rheal, we have sourced EU grass-fed Bovine Collagen, which is backed by a 12-week double-blind, placebo-controlled clinical study with proven results*.
Here's what you can realistically expect when you start to take collagen daily.
Weeks 1–3: Building the Foundation
Although you may not notice visible changes yet, your body is beginning to absorb and utilise the collagen peptides.
Collagen peptides are the building blocks of collagen, so you're already giving your body what it needs to make it - but true benefits and noticeable results will naturally take more time.
Weeks 4–6: Early Signs
Around the one-month mark, many people begin to notice subtle improvements from collagen use.
You may experience:
-
Skin feels more hydrated and supple
-
Stronger, faster-growing nails
-
Improvements in overall skin texture & appearance
Weeks 8–10: Visible Improvements
By this stage, the benefits often become more noticeable. We're talking confidence, and compliments.
Around now you may notice:
-
Fine lines beginning to soften
-
Skin looking firmer and smoother
-
Joint stiffness starting to ease, particularly after exercise or periods of inactivity
Week 12+: Clinically Proven Results
The most significant improvements in both anecdotal evidence and the clinical study were seen after 12 weeks of daily supplementation.
Participants in the study experienced:
-
Visibly firmer skin
-
A visible reduction in fine lines and wrinkles
-
73% of participants showed a measurable improvement in wrinkle appearance
These findings are based on a 12-week double-blind, placebo-controlled clinical study using the same EU grass-fed bovine collagen found in Rheal Bovine Collagen Peptides.
Why Consistency Matters
Collagen supplementation works by providing your body with the amino acids it needs to support collagen production. Because your skin naturally renews over several weeks, meaningful improvements take time.
The good news? The more consistent you are, the greater the potential benefits. Think of collagen as part of your daily wellness routine - just like eating well, staying hydrated and getting enough sleep.
With one daily serving of Rheal Collagen Peptides, you're supporting healthy skin, joints, hair and nails from within, with clinically backed ingredients you can trust.
The results are waiting for you, you've just got to wait for them.
