What’s The Best Collagen? Which Type Should You Use?

21st January 2022

21st January 2022

By Beth Shelper

In the skincare community, across Instagram and throughout the health and wellness industry, we can guarantee that you will have heard at least one person buzzing about collagen, the benefits of collagen, and the various types and forms that collagen comes in. And to be honest, it’s for good reason.

As one of the most exciting ingredients out there at the moment (big statement, we know), here at Innermost, we just knew we had to harbour the benefits of bovine collagen and integrate this super ingredient into one of our products. Voila, The Glow Booster was born!

Is marine collagen better than bovine collagen? What are some natural sources of collagen? How do we know which are the best collagen supplements?

To answer these questions, we first need to get some of the basics of collagen out of the way. For example, there are multiple different types of collagen, and a variety of formats in which for you to take them. Not forgetting the natural sources of collagen too, of course.

Bovine collagen vs marine collagen

The term animal collagen can pretty much be used to encapsulate a wide range of collagen used in health and wellness supplementations, but for the purposes of this article, and for coherence, we’re going to compare bovine and marine collagen. And then the rest. Gotta get you all clued up, after all. 

What is bovine collagen?

Simply, bovine collagen is that derived from cows. Makes sense.

What is marine collagen?

The clue really is in the name with this one: this collagen comes from fish. In fact, sometimes it’s even called fish collagen. More specifically, this collagen comes from the skin of fish.

Type 1 vs type 2 collagen

Aside from the different sources of collagen, there are also two different types, that are simply known as Type 1 and Type 2. Type 1 collagen is commonly found in the skin and tendons of mammals, whereas Type 2 is found in the cartilage instead.

The health benefits of collagen

Now you know about the many different types of collagens, it’s time to take a look at their health benefits. Amongst the many health benefits of marine collagen and bovine collagen are some of our favourites that we’ve listed below… for your convenience, of course.

Here at Innermost we use bovine collagen, but in reality, there is no real winner when it comes to the most effective. Each source of collagen provides the user with great health benefits, including the below:

  • Reported arthritis relief
  • Improved skin health
  • Bone loss prevention
  • Joint pain relief
  • Increased blood flow

What are the best collagen supplements?

One of the best things about collagen supplements is that, if you hadn’t already noticed, are incredibly versatile. As well as a variety of collagen types, there are multiple ways in which you can ingest your collagen supplement.

  • Collagen gummies

Gummies are a pretty common form of supplements due to the ability to flavour and sweeten the supplement with flavourings. As a result, though, whilst collagen gummies can create a fruity treat, this form is often quite heavily laden with sugars, which isn’t the healthiest option.

  • Collagen capsules

This is pretty self-explanatory. Similar to our capsule collection here at Innermost, or over-the-counter medicines such as Ibuprofen, collagen capsules can be taken really easily with a good gulp of water. This makes collagen capsules ideal for on-the-go use too, for those that travel regularly!

  • Collagen liquids

Again, a slightly more controversial form of collagen supplementations, collagen liquids are typically pre-made, ready to drink liquids that you can pop in your fridge to take at any time of day. Whilst this sounds ultra-convenient, many people aren’t a fan of the taste of these.

Which leads us pretty nicely onto the below…

  • Collagen powders

Arguably the most popular form, collagen powders are flavourless powders that provide individuals with the ability to add the collagen supplement to a range of food and drinks. Think coffee, tea, porridge, soup, and even home baking recipes.

Here at Innermost, we loved the versatility of the collagen powder, and opted for this form for our debut skincare product The Glow Booster.

I've Been Taking Creatine Every Day For Six Years
Something happens in March. The people who started strong in January, the ones with the new routine, the new kit, the renewed sense of purpose, are now splitting into two groups. The ones who've lost momentum. And the ones asking sharper questions. Not "what should I take?" but "what actually works?" Creatine keeps coming up. And every time it does, I notice the same pattern: people either swear by it without really understanding why, or they assume it's something bodybuilders use and leave it alone.I've been taking it every single day for six years. So let me tell you what I actually know. Why I started I didn't start taking creatine for the reasons most people assume. I wasn't trying to get bigger. I was training consistently, eating well, and hitting a wall. That frustrating place where effort stops translating into progress. A friend with a sports science background told me creatine was the most researched supplement in existence. More peer-reviewed studies than almost anything else on the market. That got my attention. So I started. And I kept going. What I noticed The first week, nothing dramatic. But over the following three to four weeks, something shifted. I could push a little harder. An extra rep. Slightly more on the bar. Training sessions that didn't end in the usual flat feeling of having nothing left. Those are marginal gains. They don't feel significant in the moment. But they compound. Over months, they're the difference between a plateau and real, measurable progression. The one time I stopped, about two years in, during a stretch of heavy travel where I got lazy about it, I felt the absence more than I expected. Not immediately. But within a few weeks, training felt duller. Less sharp. I put it back in and haven't looked back since. I also noticed something I hadn't anticipated: my thinking felt clearer on the days I trained hard. I assumed it was the exercise. I later learned creatine may have had something to do with that too. What creatine actually does Most people think of creatine as a muscle supplement. That's not quite right. What creatine does is help your body regenerate ATP, adenosine triphosphate, more efficiently. ATP is your cells' primary energy currency. It's what your muscles burn during intense effort. But it's also what your brain runs on. Here's the mechanism: during high-intensity exercise, your body depletes ATP rapidly. Creatine stored in muscle tissue, in the form of phosphocreatine, allows you to replenish that ATP faster. That's why creatine consistently improves performance in short, explosive efforts: weightlifting, sprinting, high-intensity intervals. But the same ATP recycling process happens in the brain. A growing body of research suggests creatine may support cognitive performance, particularly under conditions of stress or sleep deprivation. A 2021 study published in Scientific Reports found meaningful improvements in memory and cognitive function following supplementation. It's not a nootropic in the trending sense of the word. But the evidence is real, and it applies to more people than the gym crowd. The effective dose is well established: 3 to 5 grams per day, taken consistently. No loading phase required. No cycling. Just daily consistency, and that's where most people go wrong. What the industry does instead Creatine monohydrate has been around for decades. That's a problem for brands that need something new to sell. So new formats appear. Creatine HCL. Buffered creatine. Kre-Alkalyn. Creatine ethyl ester. Creatine gummies. Each one marketed as superior: faster absorbing, more bioavailable, easier on the stomach. The evidence doesn't support it. Multiple head-to-head comparisons, including a widely cited review in the Journal of the International Society of Sports Nutrition, found no meaningful performance advantage for alternative creatine forms over monohydrate. In some cases, the alternatives perform worse per gram of active compound. In the case of creatine gummies, several brands including some very large ones have been shown not to contain the creatine concentrations they claim on the label. What you actually want is simple: a clinically relevant dose of creatine monohydrate, taken every day. That's it. What I use The Power Booster is 100% pure creatine monohydrate, nothing added, nothing unnecessary. Five grams per serving, which sits right at the evidence-supported daily dose. It's not complicated because it doesn't need to be. The science on creatine monohydrate is already settled. The job is just to take it consistently. (If you have a friend still on the fence about creatine, forward this their way. It's one of those rare supplements where the evidence is clear enough to just recommend without caveats.) Read more
The Ingredient We Almost Didn't Put In The Energy Booster
There's a question we ask about every ingredient before it goes into a product. Not "is this trending?" Not "does it look good on the label?" Just: does the evidence actually support putting this in? Most of the time, that question is straightforward. Either the research is there or it isn't. But occasionally you land on an ingredient where the science says yes and something else gives you pause. That's where formulation gets genuinely interesting. Beta alanine was one of those decisions. What Beta Alanine Actually Does Most people who've taken a pre-workout have felt beta alanine without knowing it. It's the ingredient responsible for the tingling sensation you get in your face, your neck, your hands. That feeling has a name: paraesthesia. It's harmless. But it's also the reason we nearly left beta alanine out. Before I get to that, the science. Beta alanine is a non-essential amino acid. On its own, it doesn't do very much. But inside muscle tissue, it binds with another amino acid called histidine to form something called carnosine. And carnosine is where the real work happens. During intense exercise, your muscles produce hydrogen ions as a byproduct of energy production. It's the build-up of those hydrogen ions, not lactic acid as most people think, that causes the burning sensation and the drop-off in performance. Carnosine acts as a buffer. It mops up those hydrogen ions and delays the point at which fatigue kicks in. The research on this is substantial. A 2012 meta-analysis published in the journal Amino Acids, covering over 40 studies, found that beta alanine supplementation consistently improved exercise capacity, particularly in high-intensity efforts lasting between one and four minutes. The effect size was meaningful and reproducible. This wasn't a promising pilot study. It was a decade of accumulated evidence pointing in the same direction. In practical terms: more reps before failure. More output before you hit the wall. Sustained performance over a longer window. So why the hesitation? The decision we almost got wrong The tingling. Not because it's dangerous. It isn't. The paraesthesia from beta alanine is a well-understood pharmacological response and there is no evidence of harm at the doses used in supplementation. But we had a real concern: if someone takes The Workout Blend for the first time and feels an unexpected tingling in their face, and nobody told them it was coming, we've just lost their trust. Possibly permanently. The easy path was to leave it out. Plenty of pre-workout formulas do exactly that, either because they're being cautious or because they want a smoother consumer experience. No ingredient, no explanation required. We talked about it a lot. And the conclusion we kept coming back to was this: removing an ingredient with strong evidence because it might confuse people is not how we want to make formulation decisions. That's the same logic that leads brands to include ingredients with weak evidence because they're more familiar, more comfortable, more sellable. The answer wasn't to remove it. The answer was to be upfront about it. The tingling means the beta alanine is working. It's a real physiological response to a real ingredient doing a real thing. If we believe in the science, we include the ingredient and we explain what's happening. That felt like the right standard to hold ourselves to. What the rest of the market does Most pre-workout formulas fall into one of two categories.The first is the stimulant-heavy formula. Stacked with caffeine at doses that produce a short spike, a noticeable crash, and not much else underneath. These sell well because the immediate sensation of energy feels like evidence that something is working. It often isn't, not in any meaningful physiological sense beyond what caffeine alone would do. The second is the proprietary blend. A long list of ingredients with no disclosed amounts, making it impossible to know whether any of them are present at doses that match the research. Proprietary blends let brands list an ingredient without committing to a dose that would actually work. Both approaches optimise for perception. Neither optimises for performance. What I'd recommend The Energy Booster (soon to be renamed to The Workout Blend) contains beta alanine alongside citrulline malate, which supports nitric oxide production and blood flow during training, BCAAs at a 2:1:1 ratio to safeguard lean muscle, and natural caffeine from guarana for sustained energy without the spike you get from synthetic sources. The formulation is built around what the research supports at doses that match the evidence. If you feel the tingling the first time you take it, that's the beta alanine. It's normal, it fades within 20 minutes or so, and it's a sign the formula is doing what it's supposed to do. Read more
