23rd December 2025

By Zak Hillard

Collagen has gone from niche wellness buzzword to a must-have item on the shopping lists for a lot of people - one heck of a glow up. Looking for an easy, convenient solution, more people are reaching for supplements to help support their skin, joints, gut, and overall wellness. 

As the topic of collagen keeps growing in popularity, so does curiosity about the different types, how exactly they work, and which option might suit certain specific goals. 

We’ve put this guide together to take a closer look at one of the big players, bovine collagen. We’ll explain what it is, what the benefits are, see how it stacks up against its fishy cousin, marine collagen, and give you some practical ideas for adding more bovine collagen into your diet.

Let’s do it. 

The rise in popularity of collagen supplements

It’s no secret that collagen has become one of the most talked about supplements in nutrition and beauty circles. People are rightly interested in collagen because it’s the most abundant protein in the body, one which helps to give strength and elasticity to skin, bones and connective tissues, amongst other things.

As natural collagen production declines with age1, especially after your mid-twenties, a lot of people choose to supplement it to support their wellness routines. Studies and clinical trials have shown collagen supplementation can help with skin hydration, elasticity and joint comfort2, which explains why so many now reach for it on a daily basis. 

What is bovine collagen? 

So, what is bovine collagen exactly? Bovine collagen comes from the connective tissues, bones, and hides of cows, which are rich in this valuable protein. When these parts are processed, they produce collagen peptides which are much easier for the body to digest and absorb.

Unlike some other sources (we’ll talk about one of those later), bovine collagen typically contains a combination of Type I and Type III collagen. Type I is the most common form in the human body and is a building block for skin, bones, and tendons, whilst Type III supports the structure of skin, muscles, and blood vessels3. 

Once broken down, these peptides act as building blocks that your body can use wherever it needs them. Bovine collagen is popular because it offers a broad range of uses beyond just beauty. It supports structural tissues throughout the body and can play a role in joint, bone, and muscle health as well - it’s pretty impressive stuff.Benefits of bovine collagen

Enough of what it is, the real question is why would you use it? Bovine collagen supplements are typically used to support long-term wellness from the inside out. 

Let’s take a closer look at some of the specific benefits of bovine collagen. 

1. Skin health and appearance

One of the biggest reasons people take bovine collagen is for its skin benefits. As collagen levels decrease with age, the structure that keeps skin firm and elastic can weaken which often leads to fine lines and dryness. 

Research suggests that taking collagen supplements can help improve the hydration and elasticity of your skin over time, by providing amino acids which are needed for new collagen formation4. 

2. Joint comfort and mobility

Collagen is a key component of joint cartilage. As we get older or put stress on our joints through exercise, cartilage can wear down and that means stiffness or discomfort. Some studies indicate that regular bovine collagen supplementation may support cartilage health5, leading to better mobility and easier movement. 

3. Bone strength

Bones aren’t rigid structures that live in isolation. Our bones have a collagen framework which helps give them their resilience. Some early research shows that supplementing with collagen may support bone density3, which is a big plus for people looking to maintain their strength as they age.

4. Gut and tissue support

Some people find that collagen supports digestive comfort, which may be tied to the amino acids like glycine that are suggested to help maintain the lining of the gut wall. 

It’s suggested that some collagen supplements can also act similarly to prebiotics6 – essentially doing your gut health a big favour. 

Marine collagen vs bovine collagen

Bovine collagen isn’t the only type you’ll see on the shelves - there’s another option many people opt for. 

Let’s see how marine collagen stacks up against bovine collagen.

Source and types of collagen

As you might’ve guessed, marine collagen comes from fish skin and scales, and it is primarily consists of Type I collagen, which is great for skin, hair, and nails7. Bovine collagen comes from cow hides and bones and provides a broader profile of collagen, both Type I and Type III3. 

Absorption and bioavailability

Marine collagen peptides are often processed into a smaller form than bovine collagen peptides, which can mean slightly faster absorption into the bloodstream. This is part of why marine collagen is usually associated with quicker effects on skin appearance. 

Bovine collagen is still very well absorbed but the peptide size tends to be a little larger. 

Marine collagen vs bovine collagen benefits breakdown 

So, there’s pros and cons for each type - which one is right for you will depend on what you’re looking to get out of this extra collagen. 

  • Marine Collagen: Because it’s mostly Type I and smaller peptide size offers faster absorption, marine collagen can be particularly appealing for skin hydration and elasticity goals – but it’s not the best fit if you’re looking for more holistic support in the body.
  • Bovine Collagen: With both Type I and III, bovine collagen can offer similar benefits to marine collagen but with the addition of extra support for joints, muscles and the gut.

Have a think about what matters most to you and pick accordingly. Don’t forget to consider your dietary preferences and any allergies (fish allergies make marine collagen a pretty risky pick).

How to get more bovine collagen in your diet

If you decide bovine collagen fits your wellness goals, there are several ways to boost your intake. Allow us to share. 

1. Bovine collagen supplements

Collagen powders and capsules are quite possibly the easiest way to increase your intake. You can get hydrolysed bovine collagen blends which dissolve in liquids and mix easily into coffee, smoothies, soups, or even baking recipes. Just chuck a spoonful or two into your morning brew and you’re set. 

This is our favourite method, too, which is why we created The Glow Blend. It contains high quality hydrolysed bovine collagen peptides and is formulated to support your skin and overall wellbeing, with extra nutrients like hyaluronic acid, vitamin C, biotin and folate. 

2. Bone broth

If you want a more traditional way to up your collagen intake, it doesn’t get more traditional than bone broth. 

Traditional bone broth is made by simmering beef bones for several hours to releases collagen and minerals into the broth. Making soups or stews with this, or even just sipping it as it comes, can be a tasty way to add more collagen to your diet.

3. Collagen-boosting foods

Eating other protein rich foods that provide the amino acids your body uses to build collagen is a way to support the natural production of it. Vitamin C rich foods like citrus fruits or peppers can help the body synthesise collagen8, so pairing quality natural protein with vitamin C can be effective too.

Whichever option you pick, remember consistency is key. Collagen isn’t an overnight fix, and most studies suggest noticeable effects are seen after a few weeks to months of regular use9.

A simple switch up for a big glow up

Whether it’s for your skin, joints, gut or just overall wellness, choosing to add a bovine collagen supplement can be a simple and effective way to make a noticeable difference. 

If you’re interested in giving it a try for yourself and would like the most convenient way to do it, Innermost’s The Glow Blend makes it easy to make high quality bovine collagen a part of every day.

As with any supplement you use, make sure to pay attention to quality, sourcing, and your individual health needs to help you make the most of your new secret weapon.

The Protein Mistake That's Holding Back Your Results

The Protein Mistake That's Holding Back Your Results

I've written at length about creatine. I've written about collagen, electrolytes, the GLP-1 moment, even the science of sleep. But I've never written a personal email about protein. That's a strange omission for someone who built a brand that makes some pretty ground-breaking protein powders. So let me explain why, and then actually say the thing I've been avoiding. Protein is the most foundational supplement in the Innermost range. It's also the hardest subject for me to write about personally, because there's nothing surprising about it. Creatine had a story. Collagen had a story. Protein is well... protein. Everyone knows you should eat more of it. The mechanism is not a secret. Muscle protein synthesis, leucine threshold, net nitrogen balance. If you've been in the fitness space for more than a couple of years, you've read this before. And I think that's the problem. The familiarity makes people stop paying attention. Here's what I actually think about protein, after a decade of working in this space. Most people in their thirties and forties are under-consuming protein and don't know it. Not by a small amount. The gap between what most people eat and what the research supports for muscle maintenance and body composition outcomes is significant. Studies looking at optimal intake for adults prioritising body composition consistently point to between 1.6 and 2.2 grams per kilogram of bodyweight per day. Most people are eating somewhere between 0.8 and 1.2. The difference is not cosmetic. Adequate protein intake directly affects your ability to preserve muscle tissue during a caloric deficit. It supports recovery between sessions. It has a measurable effect on satiety, which means it influences total caloric intake downstream, not just at the point you consume it. There's a subtler point too, and this is the one I've come to think matters most: protein is the nutrient where consistency compounds most directly. The benefits of creatine saturate over time in a relatively predictable way. Collagen has a timeline that research measures in months. But protein's effect on body composition is essentially continuous. Every day you hit your target, you preserve something. Every day you don't, you lose a small amount of ground. Over a summer, that adds up. This is what I've observed personally, and it's backed by the research on muscle protein turnover. The people who maintain their body composition through summer are not, in my experience, the people who train harder during that period. Most of them train less. Their routines are disrupted. They're travelling. Their eating is less structured. The people who come back in September looking broadly the same as they left in June are the ones who kept their protein intake consistent. That's it. That's the variable. Why I take The Lean Protein I’ve been taking The Lean Protein the past few months for a straightforward reason: the protein-to-calorie ratio. Much like our other protein blends, each serving delivers over 30 grams of protein. The calorie count is low relative to that protein yield. When my training is consistent and my eating is structured, I don't think about this very much. But in the periods when those things are less reliable, that ratio becomes the thing that holds the rest together. The formula also includes acetyl-L-carnitine, inulin, pomegranate extract, and yerba mate. These aren't afterthoughts. Acetyl-L-carnitine has a research base in fat metabolism. Inulin supports satiety and gut function. The pomegranate extract is included for its antioxidant contribution to recovery. This means that the formula does more work per serving than a standard whey and just what I need going into summer. The thing the industry gets wrong about protein Most protein marketing leads with taste and price per gram. Both matter. But neither tells you whether the formula will support body composition outcomes over time. The two questions I'd ask before buying any protein powder are: what is the actual protein-to-calorie ratio, and what is the leucine content per serving.  Leucine is the branched-chain amino acid most directly linked to triggering muscle protein synthesis, and there is a threshold dose, roughly 2.5 to 3 grams per serving, below which the anabolic response is blunted. Many protein powders do not disclose this. They just list total protein and move on. The Lean Protein does not have this problem. The formula is transparent. The dose is evidence-based. One thing I'd ask you to consider: if you've never actually checked whether you're hitting your protein targets, try tracking it for three days. Most people find the gap is larger than they expected.

I've Been Taking The Glow Blend For Six Months. Here's What Happened

I've Been Taking The Glow Blend For Six Months. Here's What Happened

There's an uncomfortable truth about founders who sell supplements: most of us are too invested in our own products to give you an honest account of what they actually do. I want to try something different with this email. I’ve been taking The Glow Blend every day for six months. What follows is a genuine account of what I expected, what I noticed, what I wasn't sure about, and what I didn't notice at all. I'm telling you this partly because I think you deserve that level of honesty from the person who formulated the product, and partly because the honest account is actually more useful than a testimonial. What the evidence says before I get into my own experience Collagen is the most abundant protein in your body. It gives skin its structure and elasticity. From your mid-twenties, your body produces less of it each year. By the time most people start thinking about skin supplementation, they've already lost a meaningful amount. Hydrolysed collagen peptides, which is what's in The Glow Blend, are different from the collagen your body produces. They're pre-broken into smaller chains, which makes them bioavailable in a way whole collagen protein is not. When you consume them, they circulate in the bloodstream, where studies suggest they signal fibroblasts to produce more collagen. The mechanism is real. The research is there. The timeline The strongest evidence on collagen supplementation shows meaningful changes in skin elasticity and hydration typically at 6-8 weeks minimum, with more substantial effects at 10-12 weeks and beyond. Studies on nail growth and hair strength follow a similar curve. This is not a two-week product. Anyone selling you collagen on a 30-day challenge framework has either not read the research or has chosen to ignore it. Vitamin C as a co-factorVitamin C is not optional in this equation. It's essential for collagen synthesis at a cellular level. Without adequate vitamin C, your body cannot complete the process of building new collagen fibres regardless of how much collagen you're consuming. This is why The Glow Blend includes it, and why most budget collagen products either leave it out or include a token dose that doesn't meet the threshold. The Glow Blend also contains hyaluronic acid, which is a glycosaminoglycan that attracts and holds water within the skin. Biotin (B7) supports keratin production, which is the structural protein in hair and nails. Folic acid (B9) plays a role in cell regeneration. Each of these is in the formulation for a specific, evidence-based reason.  What I noticed and what I didn't I started in December. Six months ago. I'll be honest: December is a difficult month to start an experiment. My diet was inconsistent, my sleep was disrupted, and my skin was already taking a beating from dry air and a bit too much running around. I didn't expect to notice much quickly, and I didn't. By week six, my skin felt more comfortable. Not dramatically different. More comfortable is the right word. Less tight in the morning. Less reactive to changes in temperature. I noticed it most on long-haul flights, where my skin used to feel genuinely awful after landing and increasingly didn't.By month three, I think that my nails were growing a little faster mainly because I was cutting them more often. Whether that's the biotin, the collagen peptides, or the combination, I can't tell you, and the research doesn't give a clean answer either. I keep my nails short anyway, so my nails weren't the thing I was watching most closely (or noticed for that matter). What I was watching was my hair. I'm older now than when I launched Innermost, and density is something I'm acutely aware of. The Glow Blend contains biotin and folate, both of which support hair health, so this is where my attention went. Over these six months: a bit thicker, a bit more resilient. I keep my hair short, so I'm not pointing to length. It's the feel and the density. I'm not going to dress that up into something it isn't. I'll just say it's been one of the more encouraging parts of the experience, and at this stage that counts for a lot.Skin texture improved. This one is harder to quantify because it's subjective. But my skin looks better now than it did in December. Some of that is the improvement in light. Some of it is that I'm trying to sleep better. But I've taken enough data points over six months to think the supplement is contributing something real. Where most products fall short The collagen category is full of underdosed products. The research on skin elasticity uses doses of 2.5g to 10g of collagen peptides per serving. A significant proportion of products on the market deliver less than 1g under the assumption that customers won't check. The Glow Blend delivers 5g of hydrolysed collagen peptides per sachet, alongside the vitamin C that makes the process work. That's where the formulation sits relative to the evidence. It's not arbitrary. My honest recommendation If you're thinking about trying The Glow Blend, I'd say this: give it twelve weeks before you draw any conclusions. The evidence doesn't support a shorter timeline and neither does my personal experience. Take it consistently. The days you forget are the days the benefit doesn't accumulate.
