Liquid collagen is becoming a more popular format of collagen supplementation. It’s more convenient than powdered collagen and is frequently positioned as a “luxury” type of collagen by brands.

But is liquid collagen really any different than powdered or capsule collagen? How does the cost compare? Can liquid collagen really improve skin and joint health?

In this article we’ll answer all of these questions and more as we review medical studies on liquid collagen to give our take on whether or not it’s effective for improving skin and joint health.

We’ll also compare the cost of liquid collagen and powdered collagen, explain if there are any relevant differences and explain why we think liquid collagen is a waste of money.

Can Liquid Collagen Reverse Aging?

Collagen is one of the most well-studied dietary supplements for skin and joint health. It can be used both topically and orally, but we’ll focus on the benefits of oral collagen intake since this is how liquid collagen is taken.

A medical review published in the Dermatology Practical & Conceptual journal examined the effects of collagen consumption on skin. The study authors concluded that collagen “can contribute to reducing or delaying skin aging.”

Not only was collagen found to reduce wrinkles, but it was also clinically shown to improve skin hydration, reduce skin roughness and improve skin elasticity.

As we documented in our review of the best collagen protein powder, the maximally-effective dose of oral collagen supplements appears to be 10 grams (g) daily.

Collagen has other health effects than its anti-aging effect. It’s also clinically shown to support joint health.

A 2008 clinical trial on collagen peptides and joint pain reported that after 3 months, 80% of patients report an improvement in their joint pain symptoms.

Based on the available medical studies, we consider liquid collagen likely to have an anti-aging effect and to improve joint health when taken at an effective daily 10 g dose.

A popular YouTube health influencer and doctor named “Doctor ER” has a video highlighting other benefits of collagen:

We Tried Liquid Collagen Ourselves

As the author of this article, I wanted to try liquid collagen myself to share my thoughts on the taste and overall product experience.

I typically use powdered collagen mixed into water first thing in the morning.

For a week I used liquid collagen shots from Momentous instead.

I disliked the flavor, it was overly sweet and artificial. This is a problem with most of the liquid collagen brands I came across while researching this article. I much prefer the unflavored collagen powder mixed into water.

This supplement provided an adequate collagen dose, so I felt it was helping to support my skin and joint health. Collagen supplementation isn't something I "feel" in a visceral way.

I didn't find liquid collagen to be any more convenient than powdered collagen. I typically just take a scoop of powder and mix into water. For the liquid collagen, I cut it open and drank it from the single-serving. Both processes only take seconds.

This product costs substantially more per-serving than the powdered collagen I normally use, which is another downside.

I dislike how most liquid collagen brands (including the one I tried) are packaged in plastic, which exposes me to questionable levels of microplastics that may be less likely to exist in a powder formulation.

Overall, I don't recommend liquid collagen and don't plan to purchase it in the future.

Why Liquid Collagen is a Waste of Money

Collagen is a type of protein that is the same structurally whether it’s included in a powder, capsule or liquid formulation. There is no extra benefit to taking liquid collagen than taking collagen in powder form and adding it to water.

Liquid collagen tends to be significantly more expensive than powder collagen because the majority of the formulation by weight is water or other liquids rather than collagen, while the entire formulation by weight of a powder collagen product is just collagen.

Here’s a comparative cost breakdown:

Modere Liquid Collagen is one of the most popular collagen products on the market. As we documented in the linked review, this product costs $76.99 and doesn’t even state the collagen dose.

Collagen is included in a proprietary blend with a total dose of 4.3 g, so we’ll say (being generous to the brand) that there is 3 g of collagen in this liquid collagen product that has 30 servings.

This equates to a cost of $8.55 per 10 g collagen (which is what we consider the effective daily dose).

YouTuber Tries Liquid Collagen

A YouTube creator named “Simply Stacie” reviewed Modere’s liquid collagen and included before-and-after images of her skin and hair. She also mentions side effects that she experienced:

Conclusion

Liquid collagen can improve skin and joint health, just like any other format of collagen can. Regardless of format, there is significant clinical backing for collagen supplementation and the maximally-effective dose appears to be 10 g daily.

We do not recommend supplementing with liquid collagen for cost reasons. It’s no more effective than powdered collagen and can be over 9x more expensive. We don’t believe that there are any risks or side effects likely from liquid collagen supplementation; our concerns are cost-based only.

We recommend that consumers be wary of health brands making claims that liquid collagen is superior to other forms of collagen without proof. Such claims are evidence of a low-quality brand.
