Our Top Collagen Supplements of 2025
What is Collagen?
Collagen is the most abundant protein in the human body, responsible for maintaining the structure and elasticity of our connective tissues, including skin, hair, nails, joints, and even our gut lining. Up to 70% of skin, hair, nails and nearly 100% of connective tissues are made from collagen. Essentially, collagen acts like glue, holding our body together.
Collagen: Why Your body Needs it?
Collagen levels naturally decrease with age, typically starting from our early-30s. The body’s collagen production slows down over time, decreasing by 1% a year beginning in early adulthood. And according to the American Academy of Dermatology, women lose 30% of their skin’s collagen in the five years following menopause.
Certain lifestyle factors can speed up the level of decline. Collagen production may be affected by:
- Excessive alcohol use
- Insufficient sleep
- Lack of exercise
- Nutrient deficiencies
- Smoking
- Exposure to environmental pollution
- Sun exposure
When collagen breaks down faster than the body takes it in or makes more, it can have detrimental effects. Some of the effects are visible, while others happen beneath the surface. Low collagen is a significant contributor to aging skin. Collagen makes up 70% to 80% of skin tissue and provides skin’s structural integrity. As it decreases, the skin can look wrinkled.
The good news is that supplements can support our body’s collagen production. Research in the last decade has confirmed that collagen supplementation may help counteract some age-related collagen loss. For instance, a recent systematic review of 19 studies (encompassing over 1,000 participants) found that around 12 weeks of oral collagen supplementation significantly improved skin hydration, elasticity, and dermal collagen density.*
But as with any supplement, it’s important to have all the facts before changing your daily regimen
Collagen Benefits
There are ways to help your body increase collagen production while supporting the collagen your body already has. You can eat foods high in collagen, and you may want to consider taking collagen supplements.
Collagen supplements are a reliable resource to ensure your body gets all the collagen that it needs. You should ideally choose comprehensive collagen supplements with complementary ingredients.
Collagen supplements come in pill, powder or liquid form. Topical creams and lotions may also contain collagen, but the external application is not as effective as ingested collagen supplements.

Skin Rejuvenation
Collagen is a vital structural protein that maintains skin’s elasticity and firmness. As we age, natural collagen production slows down, causing skin to sag and wrinkles to form. Collagen supplementation helps replenish collagen stores, stimulating cells in the skin to increase the natural production of collagen and elastin—resulting in visibly hydrated, firmer and more youthful skin.
Healthy Hair and Nails
Collagen contains essential amino acids that play a key role in building keratin, the protein responsible for strong, healthy hair and nails. Supplementation provides the body with building blocks necessary to produce more resilient, thicker hair strands and less brittle nails, visibly enhancing their strength, growth rate, and appearance.
Cartilage & Joint Health
Collagen is crucial for the integrity of cartilage, the flexible tissue that cushions your joints. Supplementing with collagen provides the body with amino acids, like glycine and proline, needed to regenerate and maintain cartilage. Clinical studies indicate collagen supplements can help reduce joint pain, stiffness, and inflammation, significantly improving mobility and comfort, particularly in individuals with osteoarthritis or those with active lifestyles.
Digestive Health
Collagen contributes significantly to the structure and integrity of the gastrointestinal lining. Collagen supplementation can strengthen and heal the gut lining. This helps enhance digestion, improve nutrient absorption, and potentially alleviate digestive discomfort.
Collagen Supplement Buyers' Guide
With numerous forms available—including powders, capsules, and liquids—selecting the right collagen supplement can be a bit overwhelming. Look for products clearly labeled as ‘collagen’ or ‘collagen peptides’ without unnecessary additives or sugars. Prioritise sustainably sourced, non-GMO, and third-party tested options to ensure you’re choosing a high-quality product that truly supports your wellness goals.
A good collagen supplement should fit effortlessly into your daily routine, enhancing your wellness from the inside out.
What To Look For?
If you’re a woman in your 30s or beyond looking to try collagen supplementation, it’s important to choose the right type of product for maximum benefits. Not all collagen supplements are created equal. Here are key factors and tips to consider when selecting a collagen supplement
Source and Type of Collagen
Collagen in supplements can come from various sources, the most common being marine (fish), bovine (cow) or porcine (pig) collagen.
For skin, hair, and nail benefits, marine collagen is a popular choice – it consists primarily of Type I collagen, the most abundant in human skin. Marine collagen has smaller peptide size, which supports quicker absorption. It is also Pescatarian-friendly. High-quality marine collagen is derived from fish and is often considered cleaner and purer.
Quality and Purity
Opt for brands that emphasise quality sourcing –This can affect purity and reduce the risk of
contaminants. It’s also wise to look for products that are tested by a third party for heavy metals
and impurities. Thankfully, independent testing suggests that most collagen products on the
market are quite clean . Still, to be on the safe side, choose a supplement from a trusted manufacturer with good reviews. Collagen is generally very safe. A pure, well-sourced product will give you the best results.
Beneficial Added Ingredients
Many collagen supplements include added nutrients that work in synergy to enhance their benefits, especially for skin and joint health.
One of the most important is Vitamin C, which is essential for the body to produce and repair collagen. It also acts as a powerful antioxidant, helping to protect the skin from damage and prevent collagen breakdown. Supplements that include Vitamin C – or are taken alongside a source like orange juice – tend to be more effective.
Vitamin E is another valuable addition. It helps neutralise free radicals, which can damage collagen and accelerate signs of ageing. By protecting collagen from degradation and supporting skin elasticity, Vitamin E contributes to smoother, healthier-looking skin.
Hyaluronic acid (HA) is often included to support hydration. Naturally present in the skin and joints, HA holds water and keeps tissues plump. When taken with collagen, it can significantly boost skin moisture, elasticity, and the appearance of fine lines.
Turmeric, is well known for its anti-inflammatory properties. It can help reduce the kind of low-grade inflammation that contributes to collagen breakdown, while also supporting joint comfort and mobility – making it an ideal addition for women who want to stay active as they age.
These ingredients don’t just complement collagen – they help your body make the most of it.
Money-Back Guarantee
Choosing a brand that stands behind its product is essential. Without a guarantee, you risk wasting money on an ineffective supplement. To ensure confidence in your purchase, look for brands that offer a money-back guarantee, allowing you to try the product risk-free.
What to Avoid?
Unnecessary additives
A lack of diversity can make it less effective in restoring gut health, preventing bad bacteria overgrowth, and adapting to changing digestive needs. A multi-strain probiotic offers broader benefits and better resilience for overall well-being.
Lack of Supporting Nutrients
While pure collagen own its own is good, supplements with no added Vitamin C, hyaluronic acid, or antioxidants may not be as effective. These nutrients support collagen production and help you get more from your supplement.
