Our Top 5 Collagen Supplements 2025

Why Taking Collagen Is Important
Collagen is the most abundant protein in your body, acting as the foundation for your skin, hair, nails, joints, and even your gut. But as you age, your body naturally produces less collagen—by as much as 1% per year starting in your mid-20s. This decline can lead to wrinkles, sagging skin, thinning hair, joint discomfort, and even brittle nails.
Supplementing with a high-grade marine collagen can help:
Skin Elasticity
Nail Health
Bone Density
Hair Growth
Joint Flexibility
Hydration

Why Taking Collagen Is Important

But as you age, your body naturally produces less collagen—by as much as 1% per year starting in your mid-20s.

Why Is Marine Collagen So Effective?
Unlike other collagen sources, marine collagen is known for its high bioavailability, meaning it’s easily absorbed and used by the body. This is due to its smaller peptide size, allowing it to be efficiently transported to where it’s needed most—your skin, hair, joints, and nails. Marine collagen, particularly Type I collagen, is the closest match to the collagen found in your skin, making it the gold standard for beauty and anti-aging benefits.
Additionally, when combined with key nutrients like Vitamin C, Hyaluronic Acid, and Antioxidants, collagen supplementation becomes even more powerful, stimulating your body’s own collagen production for long-term results.
How Can You Benefit From Marine Collagen?
Adding marine collagen to your routine can lead to noticeable improvements in just weeks:
Smoother, firmer skin
Boosts skin elasticity and hydration, reducing fine lines, dryness, and signs of aging. Supports collagen production for a plumper, more youthful complexion.
Stronger, thicker hair
Strengthens hair from within, promoting growth, reducing shedding, and enhancing shine. Supports hair follicle health for thicker, fuller strands.
Healthy Nails & Joints
Supports nail strength and growth, reducing breakage and brittleness. Promotes joint mobility and flexibility, easing stiffness and discomfort.
7 Things That Separate "The Good" Collagen from "The Bad"
Many are turning to collagen supplements for long-term skin, hair, and joint support, but not all are created equal. Some use low-quality collagen, ineffective dosages, or lack key nutrients for absorption. We reviewed top formulas and identified five key features that ensure real results. If these 4 features are met, you have a quality collagen supplement:
Characteristic
Good Collagen
Bad Collagen
Potent dosage (~1000mg+) Marine Collagen
Hydrolyzed peptides for easy absorption
Includes key nutrients (Vitamin C, etc.)
Clinically tested or science-backed
No fillers, additives, or contaminants
Transparent sourcing (wild-caught, clean)
Perhaps even more important, there are certain red flags to be wary of when evaluating different brands.
When choosing a marine collagen supplement, not all products are created equal. Some formulas may seem promising but contain hidden drawbacks that can affect their quality, effectiveness, and even your health. To ensure you're getting the best possible benefits, here are three key things to avoid when selecting a marine collagen supplement.
What should I avoid?
Collagen from Unknown or Low-Quality Sources
Some brands use farmed fish or collagen blends that may contain contaminants like antibiotics, hormones, or heavy metals. Additionally, low-grade collagen has lower bioavailability, meaning your body absorbs less of it. Always check for wild-caught, sustainably sourced collagen to ensure purity and effectiveness.
Harsh Additives, Fillers, or Preservatives
Choose marine collagen that is broken down into smaller peptides - hydrolyzed collagen is easier for the body to absorb and use for skin, hair, and joint health.
Watch out for online reviews
Many companies pay for fake reviews to boost ratings, making it hard to judge a product’s true quality. While reviews can offer insight, don’t rely on them alone—do your own research. Be wary of misleading listings on marketplaces where reviews can be manipulated. For quality and safety, buy from trusted brands with verified websites that produce in the UK.

2. Nutralie Collagen
by Nutralie
The Bottom Line
The Nutralie Collagen supplement tries to offer a well-rounded formula but falls short in key areas.
Despite adding vitamin C for absorption and CoQ10 for antioxidant support, the formula feels underwhelming.
With just 370mg of collagen, it offers a short supply, meaning you’ll need to repurchase more frequently. Additionally, while it claims to support skin, joints, and bones, the lack of transparency around ingredient potency makes it hard to trust its impact.
Overall, Nutralie’s Collagen Complex feels like an average, lower-tier option that may not deliver noticeable results. There are stronger, better-formulated collagen supplements available at similar or better value.

Pros
Contains Biotin & Vitamin C
Easy To Swallow
GMO Free
Cons
No Money Back Guarantee
Low Collagen Dose
Not Made in Britain
3. Collagen Complex
by Solgar
The Bottom Line
Solgar is known for high-quality supplements, but their Collagen Hyaluronic Acid Complex fails to make second place. While it contains BioCell Collagen II®, hyaluronic acid, chondroitin, and vitamin C, the collagen dosage and origin is unclear, and it lacks key ingredients like zinc or biotin found in more advanced formulas.
The tablet form may be inconvenient, and despite its premium price, it offers less than competitors with higher doses and broader ingredient profiles. The one positive is Solgar’s high manufacturing standards, but overall, this supplement fails to stand out for skin health.

4. MyProtein Collagen
by My Protein
The Bottom Line
Myvitamins Collagen Capsules are convenient and easy to take, making them a simple addition to any routine. However, the formula is underwhelming, with just 400mg of hydrolyzed bovine Type 1 collagen per capsule—a far lower dose than more effective collagen supplements.
It also lacks essential co-factors like vitamin C, hyaluronic acid, or zinc, which are crucial for collagen synthesis and absorption. While marketed as a quick and effortless way to boost collagen levels, the low dosage makes it unlikely to deliver noticeable results for skin, hair, or joint health.
Overall, despite its convenience, this supplement falls short in potency and formulation, making it a weak contender compared to more comprehensive collagen products.

5. Collagen Tablets
by Project Nutrition
The Bottom Line
Project Nutrition’s Pure Collagen Tablets contain Peptan marine collagen, making them a pescatarian-friendly option.
However, the formula is basic, lacking key nutrients like vitamin C, hyaluronic acid, or zinc for better absorption. The tablet form may also be less convenient compared to powders or capsules.
While it offers a good collagen source, more advanced and comprehensive options are available at a similar price, and it therefore comes last in this review.
