At Core Longevity, we carefully select three of the best collagen products available in the UK, focusing on the principles that matter most to us: Quality, Purity and Purpose. We look for clean, straightforward formulations with a high-quality source of collagen and minimal unnecessary additives, added sugars or ingredients that don't serve a clear purpose.

Our reviews are independent, honest and focused on what really matters — the quality and source of the collagen, the type and amount provided, the simplicity of the formula, value for money and how well the product fits into a healthy and active lifestyle. We also consider how clearly the manufacturer communicates information about its ingredients, sourcing and quality standards.

We don't simply choose the most popular products; we look deeper so you don't have to, helping you make a more informed decision based on what is actually in the product rather than clever marketing.

Our aim is simple: to identify collagen products that offer a clear purpose, transparent ingredients and a formulation that closely reflects the Core Longevity principles.

Ancient + Brave True Collagen

At Core Longevity, we believe a good collagen supplement shouldn't need a long list of ingredients to have a clear purpose. Ancient + Brave True Collagen fits that philosophy particularly well because the formula contains 100% hydrolysed bovine collagen peptides (Type I) — nothing else. There are no added sugars, flavours, fillers or unnecessary additives, making it a simple and straightforward source of collagen that is easy to incorporate into a daily routine.

What also sets True Collagen apart is the company's investment in research and product-specific evidence. Its collagen has been assessed in a double-blind, randomised, placebo-controlled clinical trial involving healthy women aged 35–55 over a 12-week period. The research investigated a range of outcomes relating to areas such as skin, recovery, energy and joint comfort.

For Core Longevity, this combination matters: pure ingredients, a clean formula, no unnecessary extras and research involving the actual collagen product. We don't believe collagen is a magic solution, and a supplement should never replace a balanced diet and healthy lifestyle. However, if you're going to supplement, we believe choosing a straightforward, well-specified product with a clear purpose and credible evidence is a sensible approach.

That's why Ancient + Brave True Collagen earns a strong position in our Core Longevity Top 3.

Hunter & Gather Collagen Peptides

At Core Longevity, we believe that when it comes to supplements, simpler is often better. Hunter & Gather Collagen Peptides fit that philosophy particularly well because the product contains 100% bovine collagen peptides from grass-fed European cattle, with no fillers, additives or unnecessary extras. The unflavoured formula provides Type I and Type III collagen, offering a straightforward way to incorporate collagen into your daily routine without added sugar or artificial ingredients.

Quality and transparency are also important to us. Hunter & Gather states that its collagen is lab tested for purity, while the cattle are sourced from Europe and described as grass-fed. The product also provides 18 amino acids and is designed to mix easily into drinks or food, making it a practical everyday option.

For Core Longevity, this is exactly the type of formula we look for: one clear purpose, one simple ingredient, no unnecessary additives and a transparent approach to sourcing and quality. We don't believe collagen is a magic solution, but if you're going to supplement, we believe choosing a clean and straightforward product with clearly communicated ingredients makes sense.

That's why Hunter & Gather Collagen Peptides earns a strong position in our Core Longevity Top 3.

Core Longevity Verdict:
A superb example of keeping supplementation simple. With 100% bovine collagen peptides and a single-ingredient formula, there are no unnecessary flavours, sweeteners or added ingredients competing with its primary purpose. Its straightforward sourcing, clean formulation and strong value make it a particularly good fit for the Core Longevity principles of Quality, Purity and Purpose.

Wild Nutrition Collagen 500 Plus

At Core Longevity, we look for products that have a clear purpose, quality ingredients and no unnecessary additions. WILD Nutrition Collagen 500 Plus takes a slightly different approach to our other Top 3 collagen choices. It combines 3g of hydrolysed Type I marine collagen with vitamin C, vitamin E, biotin and Mesoporosil® silica, creating a broader formulation than a single-ingredient collagen product. It is unflavoured and, according to the manufacturer's product information, contains no added sugars, artificial colours, flavourings or preservatives.

What makes WILD particularly interesting is its focus on the overall formulation, rather than simply providing collagen. The company states that its marine collagen uses 500 Dalton peptides, while Mesoporosil® is included as a specific functional ingredient within the formula. WILD also states that its collagen is tested for heavy metals and meets relevant quality standards.

For Core Longevity, this means WILD scores highly for purpose, formulation and ingredient transparency, although its more complex formula means it is not as minimalist as a pure collagen product. We don't believe more ingredients automatically make a supplement better, but we do consider whether each ingredient has a clear reason for being included.

WILD Nutrition Collagen 500 Plus earns its place in our Top 3 as a more comprehensive collagen formulation for those who want collagen alongside additional nutrients, while still avoiding added sugar, artificial flavourings and unnecessary extras.

Core Longevity Rating

Purity: ★★★★½ 9/10
Clean Formula: ★★★★½ 9/10
Price & Value: ★★★★ 8.5/10
Verified Quality: ★★★★★ 9.5/10
Purpose: ★★★★★ 10/10

Overall: ★★★★½ 9.0/10

Core Longevity Verdict:
A well-designed marine collagen with a clear purpose and a thoughtful combination of ingredients. It provides 3g of hydrolysed Type I marine collagen alongside vitamin C, vitamin E, biotin and Mesoporosil® silica, while avoiding added sugar, artificial colours and unnecessary flavouring. It scores slightly lower than our purer choices because of its more complex formulation and higher price per gram, but its purposeful ingredient selection makes it a strong addition to our Core Longevity Top 3.
