The Most Effective Collagen Supplements In 2025 – A Buyer’s Guide
Discover which collagen supplements are worth buying, and which ones might fall short.
Collagen is one of the most abundant structural proteins in the body, forming much of the connective tissue that supports our skin, bones, tendons, and muscles.
In recent years, collagen has garnered global attention for its potential to support skin, hair, and nail health2,3.
Collagen makes up over 80% of our skin, and plays a role in maintaining skin elasticity and hydration. However, as we age, our bodies naturally produce less collagen, making it harder to replenish what we've lost. Starting in our 20s, we start to lose as much as 1% of our collagen each year and by the time we hit our 50s, we lose up to a third of it1.
This decline can contribute to changes in skin texture and appearance, as well as a natural reduction in joint and connective tissue function.
Numerous studies have shown that one way to support your collagen production is by taking a high quality collagen supplement. Collagen supplements are primarily made with collagen peptides (also known as hydrolyzed collagen). Unlike the collagen our bodies produce naturally, collagen peptides are composed of amino acids that are derived from animal protein, may be more readily absorbed into the bloodstream2.
Most collagen supplements are made with either bovine or marine peptides. Research has indicated that marine collagen (type 1 collagen) may be especially beneficial for supporting skin texture and hydration, as well as contributing to healthy joints and connective tissue function2,3.
What is Hydrolysed Marine Collagen and Why is it Popular?
Hydrolysed marine collagen—also known as Type I collagen—is made from peptides derived from fish skin and scales. The hydrolysis process breaks down these proteins into smaller pieces, which may support easier digestion and absorption by the body.[2]
It’s also considered the most environmentally conscious collagen source, as it uses parts of the fish that would otherwise go to waste.[4]
Marine collagen is popular for those looking to support healthy skin, hair, nails, and joints. It’s also commonly used to maintain collagen levels, assist connective tissue function, and support general wellbeing.[3]
However, in order to get the most out of what collagen supplements have to offer, it’s important to choose the right one. Keep reading to find out what criteria to look for and what to watch out for when choosing your collagen supplement.
Collagen + Nutrients for Beauty & Wellness
While collagen is the star ingredient for skin elasticity and structural support, the most effective supplements don’t stop there. The best formulas pair collagen with a nutrient complex that helps the body maintain and build its own collagen naturally, while supporting overall wellbeing.
Look for formulas that include:
- Biotin, to support healthy hair, skin, and nail strength[5]
- Vitamin C, which plays a key role in collagen production and antioxidant protection[6]
- Zinc and iodine, essential minerals that help maintain healthy skin and cellular repair[7.8]
- Lysine, an amino acid involved in collagen synthesis and tissue repair[9]
- Marine plant extracts like Fucus vesiculosus, known for their natural iodine content and metabolism support[10]
Together, these nutrients work synergistically to help you get more out of your collagen supplement, targeting both visible beauty benefits and deeper foundational support.
Choosing the Right Supplement
When it comes to choosing dietary supplements, many of us are tempted to reach for the cheapest option on the shelf. Yet, there’s a reason some are more expensive than others. Often, higher quality products are also accompanied by higher price tags. Although this means you’re spending a bit more, it also means you may be getting better ingredient quality and more reliable formulations. Keep reading to see our roundup of the 5 best collagen supplements on the market.
How You Can Benefit From Marine Collagen:
- May help support hair and nail strength
- Contributes to skin hydration and elasticity
- Supports healthy bones and muscles maintenance
- Plays a role in overall vitality and well-being
- Provides building blocks that may support healthy metabolism
- May help support joint comfort and mobility
With so many different brands and products to choose from, it can be challenging to differentiate the high-quality supplements from those that may not live up to expectations. That's why we’ve rounded up some of the top-rated collagen products available today. Keep reading to discover our picks for the top 5 collagen supplements worth considering.
What Should I Look For?
Considering all of the attributes listed above, we’ve compiled a list of the five essential criteria you should look for when choosing your collagen supplement.
Recommended by healthcare professionals
One of the most important things to look out for when choosing a supplement is that it’s recommended by healthcare professionals. These experts are more likely to support products made with high-quality ingredients and supported by traditional use or scientific research.
Find a supplement that contains marine collagen
Studies suggest that marine collagen supplements may offer certain advantages over other types of collagen, like types 2 and 3 collagen, which are derived from chicken or bovine proteins. Marine collagen peptides are known for their smaller molecular size, which may support more efficient absorption compared to other types. This can help you get more out of your collagen supplement routine.2,3
High-quality, supportive ingredients
It goes without saying, but it’s essential that the supplement you take is produced using high-quality ingredients. Look for a collagen supplement that also contains supporting nutrients like Vitamin C, Biotin, Zinc, and Iodine, which may help support healthy skin, nails, bones, and joints.
Finally, avoid products that contain synthetic additives or unnecessary fillers.
High potency
When buying your collagen supplement, look for a product with a meaningful amount of collagen peptides. Many formulations use at least 500 mg per serve, which is a commonly recommended baseline.
Money-back guarantee
Make sure that the product you buy has a clear money-back guarantee on all product purchases. This can give you peace of mind when trying a new supplement and may reflect a brand’s confidence in its formulation.
What Should I Avoid?
Poor quality ingredients and low potency
To get the most from your collagen supplement, it’s essential to choose one made with quality ingredients in meaningful doses. Avoid any supplements with less than 500mg of marine collagen peptides per serving. Also, watch out for supplements that contain any unnecessary fillers or synthetic additives.
Beware of online reviews (especially on Amazon)
Before purchasing any product, one of the first things many of us do is check online reviews. Unfortunately, these aren’t always a reliable way to assess product quality. Some companies may pay for reviews on popular platforms like Amazon to boost ratings. While it’s helpful to read feedback, it’s also important to do your own research.

8.5/10
B
Overall GradePROS
- Contains 1000mg of hydrolysed Type I marine collagen per 2-tablet serve
- Includes biotin, selenium, and vitamin C to support skin, hair, and nail health
- Effervescent tablets dissolve into a berry-flavoured drink
- No artificial colours, sweeteners, or preservatives
- Compact, travel-friendly format
CONS

- Flavoured format may not suit those preferring unflavoured supplements
- Sweetened with sucralose (an artificial sweetener)
The Bottom Line
Bioglan Collagen Effervescent stands out for its drinkable, on-the-go format and solid active profile. Each 2-tablet serving provides 1000mg of hydrolysed marine collagen, along with biotin, vitamin C, and selenium to support healthy skin, hair, and nails.
The effervescent delivery offers a refreshing alternative to traditional capsules—perfect for those who prefer a flavoured daily ritual. However, the need to mix with water may be less convenient for those after a grab-and-go option, and the berry flavour won’t suit all taste preferences.
Additionally, while it’s free from artificial colours and preservatives, it is sweetened with sucralose, which won’t appeal to everyone. Nonetheless, Bioglan remains a smart and flexible choice for collagen users looking for effectiveness with a bit of flavour and flair.
