Which brand of collagen drink should you buy?
With countless different collagen products vying for your attention, how do you really know which one will actually deliver on collagen’s big promises of glowing, firm, and all-round youthful looking skin?
Should you buy your peptides from the household-name or celebrity-backed beauty brands? Or what if there’s a lesser-known brand that’s just as good (if not better), who are so confident in their product they even offer a money back guarantee if you don’t see the promised results (none of the big brands do this)?

That’s why we’re here. We scoured the internet and braved the high street to buy and test some of 2023’s most talked about collagen products. We combed through the scientific research and tracked down beauty specialists and collagen experts to help you make an informed decision.
So keep reading to discover out top pick collagen product for 2023, and which ones may even make your skin, joint and hair problems worse.
Why Celebrities Love Collagen Peptides
The collagen market is estimated to reach £5.3 billion by 2026 for one simple reason:
We need it.
See, in addition to our hair skin and nails, our bodies use collagen to maintain the proper functioning of our muscles, joints, bones, and intestines.2
But there’s a problem. As early as our mid-20s, our bodies’ collagen factories struggle to keep up with demand…and it only gets worse as we age.

So all we’ve got to do is take in more and more collagen as we age, right? If only it were that simple…
Unprocessed collagen used by some manufacturers is too difficult for your body to absorb. So most of it simply passes through your body unused!3
That’s why consumers and scientists both swear by Collagen Peptides.
Manufacturers break down the large, unabsorbable raw collagen into smaller pieces or “peptides” via a process called hydrolysation.
In the course of our research, we discovered a few things the beauty industry probably wishes we’d keep under wraps. Including how:
The type of hydrolysation process itself has a HUGE impact on your results…
How the bovine (cow or pig) collagen most brands use (because it’s cheap) is scientifically proven in paper after paper to do almost nothing for your skin…
And most troubling of all…

Here’s what to look for in beauty focussed collagen peptides…
and what you MUST AVOID at all costs.
Must Haves
-
Collagen Quality:
Sustainable marine sourced collagen with low mercury content
-
Collagen Potency:
A minimum of 5g
-
Enzymatically Hydrolysed Collagen:
Collagen made using special enzymes absorbs FAR better than any other method.
-
Collagen Source:
Marine collagen is far superior to bovine collagen for radiant skin as it is packed full of collagen type I (which makes up 90% of the collagen in our skin).5
-
Ease Of Use:
According to customer reviews, the majority of collagen peptides drinks and powders taste horrible and/or can’t be mixed easily.
-
Synergistic Ingredients:
Collagen works best when paired with other age fighting super ingredients.
Must Avoid
-
Calorie Bombs:
Look out for nasty added sugars which can cause weight gain and acne.
-
Unknown Collagen Source:
The potential to make our problems worse mean we should ALWAYS know which specific type of collagen is used.
-
Artificial Ingredients:
Like sweeteners, preservatives, and other “fillers”. These chemicals poison your body and can reduce the absorption of important vitamins and minerals.
-
Environmentally Unfriendly Packaging:
Avoid plastics and non-recyclable packaging. Save the environment!
-
Incomplete List Of Ingredients:
Always check the ingredients list and only buy from brands that have nothing to hide!

The Bottom Line
Glow Powder Collagen by Rock & Roses has been voted #1 by our nutrition expert Simon White*, with a 9.7 out of 10 score.
What We Loved
Rock & Roses was the only brand using the special enzymatic hydrolysis process for optimal absorption3. It was also the only brand transparent about their collagen source, and therefore the only brand we can be certain is safe to consume.

Rock & Roses are the only company offering a “No questions asked” 90-day money Back Guarantee.
There’s just one small thing…Rock & Roses is a small company right now, so they don’t have massive inventory like other “household-name” beauty brands.
That’s why when people find out about Rock & Roses Glow Powder Collagen, their inventory sells out fast.

But if you’re reading this page, then you might be in luck. Rock & Roses let us know they set aside part of their recent shipment specifically for this review.
However, it’s likely Rock & Roses will sell out of their current inventory within the next 24 hours.
So if you want to try the only proven safe and effective collagen peptide product with a 90-day money back guarantee that we could find, then click the button below now.
