Hydrolyzed Collagen Peptides, Grass-Fed
What hydrolyzed collagen is
Hydrolyzed collagen is collagen broken into smaller peptides so it dissolves readily and digests easily. It is rich in glycine, proline and hydroxyproline, the amino acids that make up connective tissue.
This is sourced from grass-fed bovine hide and supplies type I and type III collagen. Unflavored and fully soluble, so it disappears into water, coffee or a smoothie.
Where the evidence is strongest, and where it is not
The largest body of randomized evidence is on skin, with joint outcomes close behind. Both describe regular use over weeks to months. What collagen is not is a complete protein for building muscle, and we say so.
| Study | Population | n | Dose | Length | Primary outcome |
|---|---|---|---|---|---|
| Skin meta 2023 Systematic review of RCTs |
Pooled trials, mostly women | — | Varied | Weeks to months | Skin hydration, elasticity and wrinkle measures improved with daily collagen peptides. Source, dose and sponsorship varied across trials. |
| Joint review Systematic review, 15 RCTs |
Active and older adults | — | Varied | Weeks to months | The most consistent effects were on joint function and joint pain, with weaker signals for body composition, strength and recovery. |
| Protein comparison Review |
— | — | — | — | Collagen is not equivalent to a complete protein for building muscle. It lacks the amino acid profile for that job. |
Both the skin and joint literatures describe effects over weeks to months of daily use. There is no overnight change to report and no timeline we will promise.
The 18 g on the panel is protein by analysis. Collagen lacks the amino acid profile to match whey for building muscle. Use it alongside your protein intake, not instead of it.
How we evaluate evidenceOne scoop a day, in anything
One level scoop, 20 g, into 8 to 10 oz of water or a beverage of your choice.
Mix for about five seconds in a shaker. Unflavored, so it disappears.
The research is built on regular use over weeks. Sold by weight, so some settling is normal.
Derived from bovine hide. Talk to a clinician before use if you are pregnant, nursing, under 18, or managing a medical condition.
One ingredient, honest testing
Bovine hide collagen peptides and nothing else. No flavors, fillers or sweeteners.
Made in a facility certified to current Good Manufacturing Practice, and the manufacturer completes third-party testing on the material. What we cannot do yet is hand you the certificate. Those documents belong to the manufacturer and are not released for marketing use, so we are not going to publish one or imply that we have. As individual products earn the volume, we are moving them to our own batch runs, which puts lot-level testing under our control and makes published results possible. When that happens for this product, it will be said here.
What it supports
Two areas with real randomized evidence, described at the level the trials support. Rebuilding cartilage or healing tendons are not claims a supplement gets to make, and they are not ours.
This is the outcome with the largest body of randomized human evidence behind it. Read it as a real signal from consistent use, not a guarantee, since source and dose vary across trials.
The most consistent findings in the connective-tissue literature are on joint function and joint pain, with weaker signals elsewhere.
Bovine hide collagen peptides and nothing else. The 18 g of protein is by analysis, and it is not a substitute for a complete protein for building muscle.
Answers

How long until I see anything?+
Weeks to months, if at all. Both the skin and joint studies used daily collagen over extended periods. There is no overnight effect.
Is this a protein powder?+
It has 18 g of protein by analysis, but collagen is not a complete protein and does not match whey for building muscle. Use it alongside your protein, not instead of it.
Types I and III, does that matter?+
It tells you what is in the tub. It is not a claim that the peptides are routed to any particular tissue, which is not something a supplement can promise.
Grass-fed, and does it dissolve?+
Yes to both. It is sourced from grass-fed bovine hide, unflavored and fully soluble in hot or cold liquids.
How do I pause or cancel a subscription?+
From your account, in one click, before the next order is charged. No email and no retention call.
What people who finished a tub said
Every review here comes from a verified order. We do not write them, we do not buy them, and we do not remove the unflattering ones.
We publish every review from a verified purchase. We remove only spam, abuse, off-topic posts, and claims that a supplement treats or prevents a disease, which we are not permitted to publish. Those rules apply to five star reviews exactly as they apply to one star reviews.
The EO VITA promise
EO VITA builds products around the best available research. Everything we sell is made in a GMP certified facility, and the manufacturer completes third-party testing on the material. If you are not satisfied with what you receive, tell us and we will make it right.
Third-party tested material
Every product is made in a GMP certified facility, and the manufacturer completes third-party testing on the material. We are not able to publish those certificates yet, and we say so on the page rather than implying otherwise.
Science-based
Everything we sell is grounded in peer-reviewed human research, and we tell you who funded each trial. Where the evidence is thin or negative, we say so rather than filling the gap with a louder claim.
We take it too
Every product we make is used regularly by the team at EO VITA. If we do not take it ourselves, we do not sell it to you.
Where it sits in the range
Collagen is the connective-tissue product in the lineup, about skin and joints rather than the mitochondrial-energy thread the others sit on. We keep it honest: real evidence for skin and joints, and no claim that it rebuilds tissue on demand.
Three things worth knowing before you buy any collagen
Skin is the strongest evidence
The largest body of randomized trials is on skin hydration and elasticity, with joints close behind. That is what we claim, and no more.
Not a complete protein
The 18 g of protein is by analysis. Collagen lacks the amino acid profile to match whey for building muscle, so use it alongside your protein, not instead of it.
Consistency, not overnight
Effects in the research come from daily use over weeks to months. There is no immediate change to report and no timeline we will promise.
