When comparing collagen supplements, it’s easy to focus on the price of the pouch. But does a lower-priced collagen supplement always offer better value?
The answer is often no.
To make a fair comparison, it’s important to look beyond the headline price and consider the amount of collagen provided, the number of servings, the cost per gram, the supporting ingredients and the scientific evidence behind the formula.
What is the best value collagen supplement?
The best value collagen supplement is not necessarily the cheapest. When comparing collagen supplements, it is important to consider the cost per serving, the amount of collagen provided, supporting ingredients, clinical evidence and subscription savings. A higher-priced collagen supplement may offer better value if it delivers more collagen per serving and contains ingredients that support collagen formation and skin health.
Why comparing collagen by pouch price can be misleading
Many collagen brands advertise a lower pouch price, making them appear more affordable at first glance. However, the true value of a collagen supplement comes from what you’re actually getting inside the pouch.
When comparing collagen supplements, we recommend looking at:
✔ Cost per serving
✔ Cost per gram of collagen
✔ Daily collagen intake
✔ Subscription savings
✔ Supporting active ingredients
✔ Clinical research and evidence
This provides a much more meaningful comparison than pouch price alone.
It’s also important to remember that the quality we bring to you begins with sourcing. That’s why we use responsibly sourced marine collagen from trusted suppliers, selected for its purity, traceability and high standards of sustainability. Our collagen is sourced from certified suppliers and independently verified for purity and traceability.
How do Rejuvenated Collagen Shots compare?
At first glance, Rejuvenated Collagen Shots may appear more expensive than some collagen powders on the market. However, when compared on a like-for-like basis, the numbers tell a different story.
On subscription:
- Rejuvenated Collagen Shots: 70p per 5g serving / £1.40 per 10g serving – 14p per gram
- Ancient + Brave collagen power: 77p per 5g serving – 15p per gram
- Absolute Collagen liquid collagen sachets: £2.00 per serving – 25p per gram
- Absolute Collagen marine collagen powder + Vitamin C: 17p per gram
Importantly, each serving of Collagen Shots contains 10,000mg of hydrolysed marine collagen, meaning customers can choose to take a full 10g serving or split the serving into two 5g servings, effectively providing up to 60 servings from a 30-day pouch.
When viewed through the lens of cost per serving and cost per gram, Collagen Shots offer exceptional value compared with many leading collagen supplements in the UK.

Beyond price: what should you compare in a collagen supplement?
Not all collagen supplements are created equal. While some collagen products contain collagen alone, others are formulated with additional nutrients that help support collagen formation, skin hydration and healthy ageing.
Rejuvenated Collagen Shots combine:
✨ 10,000mg hydrolysed marine collagen peptides
✨ Vitamin C to support normal collagen formation
✨ Hyaluronic acid for hydration support
✨ Antioxidants including acai berry extract
✨ Zinc and copper to support healthy skin
When comparing the best collagen supplements in the UK, it is important to consider both the collagen content and the supporting ingredients included within the formula.
Our formulation goes beyond collagen alone. Collagen Shots are built around a targeted amino acid profile, designed to work alongside Vitamin C, hyaluronic acid and antioxidants to support the body’s natural collagen production more effectively. This precise formulation is unique to Rejuvenated and it’s why the results of our independent clinical trial speak for themselves.
The importance of clinical evidence
At Rejuvenated, we believe supplements should be supported by meaningful science as well as real-world results.
Not only do we carefully select ingredients with proven clinical efficacy, but we also wanted to provide our customers with additional reassurance by carrying out an independent clinical study on our Collagen Shots formula. To provide our customers with additional confidence in our formula,
Collagen Shots were evaluated in an independent 60-day clinical trial at GBA Polska Analytical Laboratories. The study involved 30 participants and demonstrated outstanding results across key indicators of skin health and appearance, supporting our commitment to science-led healthy ageing and wellbeing from within.
✔ 93% saw improved skin elasticity
✔ 86% saw improved skin radiance
✔ 86% saw improved skin hydration and moisture levels
✔ 86% saw an overall improvement in appearance
The study involved healthy women aged 35–55 and was conducted by an independent third-party laboratory following recognised clinical research standards.
Best value collagen supplements: what really matters?
If you’re searching for the best collagen supplement in the UK, value should be measured by more than price alone.
A lower-cost collagen powder may not provide the same collagen dosage, supporting nutrients, clinical evidence or long-term subscription value.
The best collagen supplement is one that delivers:
✔ Effective collagen levels
✔ Supporting active ingredients
✔ Proven scientific evidence
✔ Excellent value per serving
✔ A routine you can maintain consistently
The bottom line
Comparing collagen supplements isn’t simply about finding the cheapest pouch.
It’s about understanding the cost per serving, the amount of collagen you’re receiving, the quality of the formulation and the evidence supporting the results.
When you compare collagen supplements on a like-for-like basis, Rejuvenated Collagen Shots offer exceptional value, clinically backed results and a comprehensive beauty-from-within formula designed to support healthy ageing, hydration and skin health.
