Best Collagen Supplement for Sagging Skin UK 2026: 7 That Actually Work

If you’ve noticed your skin losing that youthful bounce, you’re not imagining it. From your mid-twenties, your body produces roughly 1% less collagen each year, and by the time you hit 50, you’ve lost nearly half of the collagen in your skin.

The result? Sagging around the jawline, loss of firmness in the cheeks, and skin that simply doesn’t snap back like it used to.

The good news: clinical research suggests that collagen supplementation can genuinely help. A 2019 systematic review of 11 studies found that oral collagen peptides improved skin elasticity and hydration within 8 to 12 weeks.

Another double-blind, placebo-controlled trial demonstrated significant improvements in skin elasticity after just 4 weeks of supplementation.

For sagging skin specifically, bovine collagen is often the better choice. It contains both Type I and Type III collagen (the primary types found in human skin), and research suggests grass-fed bovine sources offer excellent bioavailability.

We’ve analysed customer reviews, clinical evidence, and ingredient quality to identify the best bovine collagen supplements for sagging skin available in the UK. Here are seven that actually deliver results.

1. Ancient + Brave True Collagen – Best Overall for Sagging Skin

Type: Bovine Collagen (Grass-Fed) | Dose: 5g per serving | Format: Powder | Price: £32 for 200g

Why It’s Our Top Pick

Ancient + Brave True Collagen has earned its reputation as the UK’s premium bovine collagen for good reason. Sourced from grass-fed, pasture-raised European cattle, it delivers pure hydrolysed collagen peptides with zero additives, flavours, or fillers.

The 5g serving provides Types I and III collagen, both essential for skin structure and elasticity. According to clinical research, doses as low as 2.5g daily can improve skin elasticity, making Ancient + Brave’s serving size clinically relevant.

What sets this brand apart is their commitment to sourcing. The collagen comes from cattle raised without hormones or antibiotics, and the powder dissolves completely in hot or cold liquids without any taste or texture.

What Customers Say

With over 50,000 UK customers, the feedback is consistently positive. Users report improvements in skin firmness typically appearing around the 8-week mark, with many noting that their skin feels “plumper” and more hydrated.

Several reviewers specifically mention improvement in neck and décolletage sagging, areas often overlooked by other skincare approaches. The flavourless formula is frequently praised for its versatility in coffee, smoothies, and even soups.

Pros

• Premium grass-fed, pasture-raised European source
• Completely flavourless with excellent mixability
• Type I and III collagen (ideal for skin)
• No additives, fillers, or artificial ingredients

2. Protein Works Clear Collagen 360 – Best Value

Type: Bovine Collagen (Hydrolysed) | Dose: Varies by serving | Format: Powder | Price: £21 for 480g

Why We Rate It

Protein Works has created an exceptional value proposition with Clear Collagen 360. At just £21 for 480g, it’s one of the most affordable premium collagen powders on the market, yet it doesn’t skimp on quality or formulation.

What makes this stand out is the enhanced formula. Unlike pure collagen powders, Clear Collagen 360 includes vitamin C (essential for collagen synthesis, as shown in this study) and hyaluronic acid for additional skin hydration benefits.

The “Gold Innovation” award-winning formula uses premium hydrolysed bovine collagen peptides that dissolve clearly in water, hence the name. This makes it perfect for adding to any drink without altering the appearance or taste.

What Customers Say

Reviews highlight the exceptional value and the added benefits of vitamin C and hyaluronic acid. Users appreciate that they’re getting a comprehensive skin support formula rather than just collagen alone.

The 480g pack size means it lasts significantly longer than competitors, making the cost per serving remarkably low. Many reviewers note visible improvements in skin texture and firmness after 6 to 8 weeks.

Pros

• Outstanding value at £21 for 480g
• Enhanced with vitamin C and hyaluronic acid
• Award-winning Gold Innovation formula
• Dissolves clearly without taste or texture
• Natural and unflavoured for versatile use
• Large pack size lasts a long time

Cons

• Exact collagen dose per serving not prominently displayed
• Less premium positioning than boutique brands
• Sourcing details less transparent than competitors

Best For

Budget-conscious buyers who want more than just basic collagen. Ideal if you want vitamin C and hyaluronic acid included without buying separate supplements.

3. Vital Proteins Collagen Peptides – Best High-Dose

Type: Bovine Collagen (Grass-Fed) | Dose: 20g per serving | Format: Powder | Price: £44 for 587g

Why We Rate It

Vital Proteins is the world’s best-known collagen brand, endorsed by celebrities including Jennifer Aniston. Their flagship Collagen Peptides powder delivers an impressive 20g of collagen per serving, the highest dose on this list.

This substantial dose is particularly relevant for sagging skin. Research suggests that higher doses (10g+) may produce faster and more pronounced results for skin elasticity, making Vital Proteins an excellent choice for those wanting aggressive supplementation.

The collagen is sourced from grass-fed, pasture-raised bovine and provides Types I and III. The powder is unflavoured, dissolves easily in hot or cold liquids, and is Paleo and gluten-free certified.

What Customers Say

UK reviews are overwhelmingly positive, with users praising the quality and the noticeable effects of the high dose. Improvements in skin firmness and elasticity are commonly reported after 8 to 12 weeks of consistent use.

The iconic blue tub is now widely available in UK retailers including Holland & Barrett and major supermarkets, making it easy to repurchase.

Some users note that prices are higher than UK-native brands, though the quality and brand reputation justify this for many.

Pros

• Highest dose on this list at 20g per serving
• Trusted global brand with strong reputation
• Grass-fed, pasture-raised bovine source
• Type I and III collagen for skin
• Unflavoured and dissolves easily
• Widely available in UK retailers

Cons

• More expensive than UK alternatives
• 587g tub provides fewer servings due to high dose
• Some batches reported to clump slightly

Best For

Those who want maximum collagen intake per serving and prefer an established international brand. Excellent for more advanced skin sagging where higher doses may be beneficial.

4. Hunter & Gather Collagen Peptides – Best Pure Formula

Type: Bovine Collagen (100% Grass-Fed) | Dose: 13g per serving | Format: Powder | Price: £34 for 400g

Why We Rate It

Hunter & Gather takes a “just one ingredient” approach that appeals to purists. Their collagen peptides contain nothing but 100% grass-fed bovine collagen, sustainably sourced from European farms.

Each 400g pouch delivers 13g of collagen peptides per serving, providing Types I and III collagen specifically beneficial for skin and joints. The powder is completely unflavoured and mixes seamlessly into any drink, hot or cold.

The brand’s transparency about sourcing is refreshing. They clearly state their collagen comes from European pasture-raised cattle, and the single-ingredient formula means you know exactly what you’re getting with no hidden additives.

What Customers Say

Reviews consistently praise the clean formula and excellent mixability. Users report that it dissolves completely without any taste, making it easy to add to morning coffee or collagen smoothies.

Improvements in skin elasticity and firmness are typically noticed after 8 to 10 weeks. The recyclable packaging is also mentioned positively by environmentally conscious buyers.

Pros

Those who want pure, single-ingredient collagen without any extras. Ideal for people who already take vitamin C separately or prefer to control exactly what they consume.

5. Revive Multi Collagen Protein – Best Multi-Collagen

Type: Multi-Source (Bovine, Chicken, Marine, Eggshell) | Dose: 20g per serving | Format: Powder | Price: £14.99 for 400g

Why We Rate It

Revive takes a different approach by combining multiple collagen sources into one comprehensive formula. Their Multi Collagen Protein includes grass-fed bovine, free-range chicken, wild-caught marine, and eggshell membrane collagen.

This “five-phase essential collagen complex” delivers Types I, II, III, V, and X collagen, covering virtually all collagen types found in the human body. While Types I and III are most relevant for skin, Type II supports cartilage and may offer additional joint benefits.

The 400g pack size offers exceptional value, and the 20g serving provides a substantial collagen dose. The powder is unflavoured and suitable for keto and paleo diets.

What Customers Say

Users appreciate the comprehensive approach and excellent value of the 400g bag. The multi-source formula appeals to those who want broad-spectrum collagen support rather than targeting a single type.

Results for skin sagging are comparable to pure bovine options, with most users noticing improvements in firmness and elasticity around the 8 to 12 week mark. The unflavoured powder mixes well in both hot and cold drinks.

Pros

• Five collagen types from multiple sources
• Excellent value: 400g pack size
• High 20g dose per serving
• Includes grass-fed bovine and wild-caught marine
• Keto and paleo diet friendly

6. NeoCell Super Collagen – Best US Brand

Type: Bovine Collagen (Grass-Fed) | Dose: 10g per serving | Format: Powder | Price: £28.99 for 400g

Why We Rate It

NeoCell has been a trusted name in collagen supplements for over 20 years, and their Super Collagen powder is one of the best-selling collagen products worldwide. It’s a great sports-focused collagen powder for those on the go, and mixes well using a portable smoothie maker, unlike some others on this list. This means you can mix it at home, or in the gym for a post-workout shake.

The formula delivers 10g of grass-fed bovine collagen per serving, providing Types I and III.

What sets NeoCell apart is their hydrolysis process. They use enzymatic hydrolysis to break collagen into highly bioavailable peptides, which research suggests improves absorption and efficacy.

The powder is Paleo and Non-GMO friendly, unflavoured, and mixes into both hot and cold liquids. At £28.99 for 400g (40 servings), it offers solid value from an established brand.

What Customers Say

Long-term NeoCell users frequently mention consistent results over months and years of use. The brand’s established reputation provides confidence, and many UK buyers have switched from other brands after experiencing better results with NeoCell.

Improvements in skin firmness are typically reported after 6 to 8 weeks, with continued benefits at the 12-week mark. The neutral taste and good mixability are consistently praised.

Pros

• Established brand with 20+ year track record
• 10g collagen per serving (clinically relevant dose)
• Grass-fed bovine, Types I and III
• Paleo and Non-GMO friendly
• Enzymatically hydrolysed for better absorption
• Good value at £28.99 for 40 servings

Cons

• US brand (less UK-focused customer service)
• Packaging less premium than boutique brands
• Occasionally out of stock on Amazon UK

Best For

Those who prefer established, science-backed brands with long track records. Good choice for anyone wanting a reliable, mid-range option from a trusted manufacturer.

7. Kollo – Best Marine Alternative

Type: Marine Collagen | Dose: 10,000mg per sachet | Format: Liquid Sachets | Price: ~£67/month

Why We Include It

While this guide focuses on bovine collagen, we recognise that some readers prefer marine-sourced alternatives. Kollo is the standout marine option if bovine isn’t suitable for your dietary preferences or if you have beef allergies.

Each daily sachet delivers 10,000mg of premium Naticol marine collagen alongside vitamin C, B vitamins, and l-lysine. The liquid format offers potentially faster absorption than powders, and the tropical flavour is genuinely pleasant.

However, for sagging skin specifically, bovine collagen’s combination of Type I and Type III may offer slight advantages over marine’s primarily Type I content. If you have no dietary restrictions, we’d recommend the bovine options above.

What Customers Say

Users report visible improvements in skin firmness within 4 to 6 weeks, likely due to the high dose and liquid format. The convenient sachets and pleasant taste mean compliance is high, which matters for long-term results.

The premium price is the main consideration, at roughly double the monthly cost of powder alternatives.

Pros

• Highest dose available (10,000mg)
• Convenient liquid sachets, no mixing required
• Added vitamin C, B vitamins, and l-lysine
• Pleasant tropical taste
• Good option for those avoiding beef

Cons

• Most expensive option on this list
• Marine source only (Type I primarily)
• Only available via subscription
• Not suitable for fish allergies

Best For

Those who prefer marine over bovine collagen, have beef dietary restrictions, or want the convenience of ready-to-drink sachets regardless of cost.

Why Collagen Helps Sagging Skin

Collagen is the most abundant protein in your body, making up around 75 to 80% of your skin’s dry weight. It provides the structural framework that keeps skin firm, plump, and resilient.

Think of collagen fibres as the scaffolding that holds your skin up. When you’re young, this scaffolding is dense and strong. As you age, the scaffolding weakens: collagen fibres break down faster than your body can replace them, and the new fibres produced are often of lower quality.

The Science

When you take hydrolysed collagen (collagen peptides), these small protein fragments are absorbed into your bloodstream and distributed throughout your body. Research published in the Journal of Cosmetic Dermatology suggests they do two things:

1. Provide building blocks: Your body uses the amino acids (particularly glycine, proline, and hydroxyproline) to synthesise new collagen
2. Stimulate production: Collagen peptides appear to signal your fibroblasts (collagen-producing cells) to increase collagen synthesis

A 2019 meta-analysis of 11 randomised controlled trials found that collagen supplementation significantly improved skin elasticity, hydration, and dermal collagen density compared to placebo. The effects were consistent across different collagen sources and doses.

Why Bovine Collagen for Sagging Skin?

Bovine collagen contains both Type I and Type III collagen in proportions similar to human skin. Type I provides structure and strength, while Type III supports skin suppleness and elasticity. This combination makes bovine particularly effective for addressing sagging and loss of firmness.

Additionally, research indicates that grass-fed bovine collagen offers excellent bioavailability, meaning your body can efficiently absorb and utilise the peptides.

How Much Collagen for Skin Tightening?

Based on clinical research, here are the recommended daily doses for skin benefits:

Goal	Minimum Dose	Optimal Dose
General skin health	2,500mg	5,000mg
Visible firmness improvement	5,000mg	8,000 to 10,000mg
Significant sagging concerns	8,000mg	10,000mg+

Most clinical studies showing significant improvements in skin elasticity used doses between 2,500mg and 10,000mg daily. For sagging skin specifically, we recommend aiming for the higher end of this range: at least 5,000mg, ideally 8,000 to 10,000mg.

All the products on this list provide clinically relevant doses, with Vital Proteins and Revive offering the highest at 20g per serving.

How Long Until You See Results?

Patience is essential with collagen supplementation. Unlike topical skincare that works on the surface, collagen supplements work from the inside out, and that takes time.

We actually have a whole article on how long it takes before you see results from collagen supplementation, so make sure to give that a read for more detailed information.

Typical Timeline

Based on clinical trial data, here’s what to expect:

• Weeks 1 to 4: No visible changes, but collagen is being absorbed and distributed throughout your body
• Weeks 4 to 8: Some users notice improved skin hydration and texture; early improvements in elasticity may begin
• Weeks 8 to 12: Most users see noticeable improvements in firmness and elasticity; this is when clinical trials typically measure significant results
• Weeks 12 to 24: Continued improvement; best results typically seen at 3 to 6 months of consistent use

The key is consistency. Missing days here and there won’t ruin your results, but taking collagen sporadically won’t deliver the cumulative benefits that daily supplementation provides.

Best Collagen Types for Skin

There are at least 28 types of collagen in the human body, but for skin health, you only need to focus on a few:

Type I Collagen

Makes up 80% of your skin’s collagen. Responsible for skin structure, strength, and elasticity. This is the most important type for addressing sagging skin. Found in both marine and bovine collagen.

Type III Collagen

Works alongside Type I to provide skin structure and elasticity. Important for skin suppleness and hydration. Found primarily in bovine collagen, which is one reason we recommend bovine sources for sagging skin.

Type II Collagen

Primarily found in cartilage and better for joint health than skin. Included in multi-collagen formulas like Revive but not essential for skin-focused supplementation, it’s the least frequently available collagen type through commercial formulas.

You can learn more about the types of collagen, and what collagen is, in our collagen basics article series.

Why Bovine Is Often Better for Sagging Skin

Bovine collagen naturally contains both Type I and Type III in proportions similar to human skin. Marine collagen is primarily Type I only.

While both can be effective, the combination of Types I and III in bovine may offer slight advantages for addressing sagging and loss of firmness.

That said, the most important factors are dose, consistency, and quality of hydrolysis (how well the collagen is broken down for absorption), not just the source.

We explored the difference between Bovine and Marine collagen for hair in a recent article, and a lot of the benefits are also shared with your skin’s health and elasticity.

Frequently Asked Questions

Can collagen really tighten sagging skin?

Clinical research suggests yes: multiple studies show that oral collagen supplementation improves skin elasticity and dermal collagen density.

However, results vary between individuals, and collagen works best as part of a broader approach including sun protection, hydration, and healthy lifestyle habits. It won’t replace surgical lifting for significant sagging, but it can noticeably improve mild to moderate skin laxity.

Is bovine collagen better than marine for sagging skin?

For sagging skin specifically, bovine collagen may have a slight advantage because it contains both Type I and Type III collagen (the primary types in human skin).

Marine collagen is primarily Type I only. That said, both sources have clinical evidence supporting their effectiveness for skin health.

How long do I need to take collagen to see results?

Most people notice initial improvements in skin hydration and texture within 4 to 8 weeks. Visible improvements in firmness and elasticity typically appear at 8 to 12 weeks.

For best results with sagging skin, plan to supplement for at least 3 to 6 months and consider ongoing maintenance.

What’s the best time to take collagen for skin?

There’s no definitively “best” time: consistency matters more than timing. Many people prefer taking collagen in the morning with breakfast or in their coffee. Check out our taste profile article if you’re wondering what bovine collagen tastes like.

Some research suggests taking collagen on an empty stomach may improve absorption, but the difference is likely minimal. Choose a time that fits your routine and stick with it.

Should I take vitamin C with collagen?

Vitamin C is essential for collagen synthesis, so taking them together can be beneficial. Research shows that vitamin C is required for your body to produce new collagen.

Some products on this list (like Protein Works Clear Collagen 360) include vitamin C, while others are pure collagen. If you choose a pure formula, consider taking a separate vitamin C supplement or consuming vitamin C-rich foods.

Are bovine collagen supplements safe?

Bovine collagen supplements have an excellent safety profile and are generally well-tolerated. Side effects are rare but may include mild digestive discomfort in some people.

If you have allergies to beef, choose a marine collagen alternative like Kollo. Always consult your GP if you have underlying health conditions or concerns.

The Bottom Line

For sagging skin, our top recommendation is Ancient + Brave True Collagen for its premium grass-fed source, clean formula, and proven track record with UK customers. The combination of Type I and Type III collagen makes it particularly effective for skin firmness and elasticity.

Prefer pure, single-ingredient collagen? Hunter & Gather keeps it simple with 100% grass-fed bovine collagen and nothing else.
