Scientific Ingredient Analysis

Ingredients list from

In the ingredient breakdown below, we focused on the active ingredients in Collagen Glow Berries: Type 1 Hydrolyzed Nitta-Wellnex Marine Collagen, Vitamin C and Bilberry Extract.


Type 1 Hydrolyzed Nitta-Wellnex Marine Collagen® (5500mg)

At first glance, this ingredient stacks up well against other high-end collagen supplements:

  1. Marine Collagen: Compared to bovine collagen, marine collagen is known for stronger efficacy and faster absorption.

  2. Hydrolyzed For High Bioavailability: Hydrolysis ensures smaller collagen structures (or peptides) that skin tissues can absorb efficiently.

  3. Type 1 Collagen For Anti-Aging: Type 1 collagen is the best form of collagen for skin aging. It forms collagen that supplies firmness, suppleness, and strength to the skin.

  4. Effectively-dosed: Most research studies conclude that 5000mg is the minimum effective dose for collagen supplementation.


But Is This Collagen Unique?

While many brands keep the source of their collagen a secret, The Purest Co takes a transparent approach.

Their website states they source their collagen from Wellnex, a leader in collagen R&D.

But what makes their collagen unique?

According to Wellnex:

“Bioavailability trials revealed PO and OG in high concentrations within the human bloodstream following oral consumption of Wellnex collagen peptides. Additional studies confirmed accumulation of these bioactive compounds in specific tissues, including the skin and cartilage, via radio labeling. Detection of PO in human urine following consumption also indicate that these dipeptides are uniquely resistant to peptidases (enzymes that break down peptides into single amino acids) within the human body. Building on this body of scientific knowledge, multiple human clinical trials have confirmed that collagen peptides with higher levels of PO-OG elicit greater physiological benefits, when compared to standard collagen peptide ingredients, over the same dosage and duration.”

In short:

Unlike regular collagen, this award-winning collagen lasts longer in your body without breaking down, which makes it work better and faster.

This may be why some users see results in just a few days.

A customer’s review of Collagen Glow Berries.


Does It Hold Up In A Clinical Trial?

The most crucial proof we found is a randomized, placebo-controlled, double-blind trial published in the Japanese Pharmacology & Therapeutics journal:

In this landmark study, participants who consumed Wellnex’s patented collagen saw improved facial skin hydration, elasticity and texture after 4 weeks.

These improvements led to the famous “glowing skin”.

Why this study is important:

  1. It was performed on Asian women between the ages of 30-55. This makes the results very relevant to older Asian women struggling with signs of aging.

  1. Other studies required ingesting up to 3 times the amount of collagen in order to see results. But in this study, participants only consumed less than 1 teaspoon of the patented Wellnex collagen, and still achieved significant results.

  1. Results appeared as early as 4 weeks. This is in contrast with studies on regular collagen, which took around 6-12 weeks instead.

For these reasons, Wellnex’s collagen stands out as a superior collagen – with rapid and intensive benefits for aging skin.

Our Assessment:

Type 1 Hydrolyzed Nitta-Wellnex Marine Collagen® is the most potent collagen ingredient we have ever analyzed.

And the effective dose is 2500 mg/day, but Collagen Glow Berries provides more than twice the amount at 5500 mg/day.


Vitamin C (250 mg)

When it comes to collagen production, Vitamin C is an essential ingredient. In fact, studies show even a little amount of vitamin C supplementation can help support collagen synthesis.

Our Assessment:

Vitamin C is a necessary ingredient to boost collagen production, and Collagen Glow Berries includes an effective dose of 250 mg.


Bilberry Extract (100 mg)

Especially abundant in “dark antioxidants” called anthocyanins, Bilberry Extract is studied to suppress inflammatory symptoms like swelling, as well as protect against damage from UV rays.

Research indicates these “dark antioxidants” have a hand in boosting levels of collagen, elastin and hyaluronic acid in skin too.

The result is a firmer, bouncier and more hydrated complexion.

Our Assessment:

Bilberry Extract is a powerhouse ingredient in Collagen Glow Berries. Nonetheless, further human trials are needed to conclude whether 100mg/day of Bilberry Extract is indeed effective.


Does Collagen Glow Berries Really Work?

There’s compelling evidence to suggest Collagen Glow Berries may live up to its claim to support a firmer, glowing complexion.

This is primarily due its powerful collagen ingredient, Nitta-Wellnex Marine Collagen®, delivered at double the effective dosage.

But will it perform as well as a Botox shot? Or help you look twenty years younger? Probably not. You'd be better off looking for an aesthetic doctor for that.


Real Collagen Glow Berries Reviews

One user, Kaila, shared a genuine review of her use of Collagen Glow Berries. She explained it helped alleviate her eczema (skin inflammation) symptoms:

Another customer, Sue, reported softer and more moisturized skin, after taking Collagen Glow Berries.

Collagen Glow Berries has also gotten over 2,800 independent reviews on Shopee, garnering an overall 4.9 out of 5 stars:

The product did attract a few 1-star reviews. Here’s a testimonial from a user who didn’t notice results:


Is Collagen Glow Berries Cost Effective?

When we looked at Collagen Glow Berries in comparison to other liquid marine collagen drinks, here’s what we found:

While not cheap, Collagen Glow Berries is the most economical option.

For example, other products we reviewed cost at least S$130 for a 30-day supply – much higher than what we paid for Collagen Glow Berries.

That’s why we consider Collagen Glow Berries to offer the most bang for buck for shoppers.



We believe Collagen Glow Berries is an effective collagen supplement with proven anti-aging benefits.

It surprised us with a powerhouse collagen ingredient, Nitta-Wellnex Marine Collagen, backed by 25 global patents, clinical effectiveness and endorsed by aesthetic doctors.

While not exactly cheap, it provides better value than high-end "premium" collagen supplements — due to superior ingredients and higher collagen content per serving.

One potential drawback worth mentioning is that Collagen Glow Berries is often sold out. This may be frustrating for those who rely on it as part of their daily skincare routine. It’s recommended to consider this fact, or stock up in advance, if you intend to take a collagen supplement for the long term.
