By Zak Hillard

Even with a balanced diet and the best intentions, it’s not easy to make sure your body is getting all the essential nutrients it needs to do its job properly.

From supporting your energy levels and immunity to aiding muscle recovery and cognitive performance, the right supplements can be the secret weapon you need to make a noticeable difference in how you feel day-to-day.

However, it isn’t always quite that straight forward. With so many opinions and guidelines out there, it can be tough to figure out which are the best supplements for your health.

For those wondering ‘what supplements should I be taking?’ Let’s break it down.

The most important daily supplements

To tackle the question of what you should be taking daily to enhance your bodies performance, we’ll go over some of the core supplements which can have the biggest impacts on your general health. Depending on your own personal diet and lifestyle, your own specific needs can differ, so read through to find which ones might be best for you.

Fibre

We’re gonna shock you with a stat. Only 9% of UK adults meet the daily recommended amount of fibre. Suitably shocked? Good.

Fibre is found in many different foods, but in order to get enough you need to be eating a pretty varied and nutritious diet. Sadly, lots of us are not. A diet low in fibre can lead to a range of digestive problems (such as constipation, bloating and IBS), as well as heart disease and some cancers.

As such, a fibre supplement can be one of the best supplements for your health and is a great way to ensure things are moving smoothly in the bathroom.

Vitamin C

Vitamin C is one of the most widely-known vitamins, famous for its presence in a humble glass of orange juice. Our bodies don’t produce vitamin C organically, so working it into your diet through foods, drinks or supplements is important.

Vitamin C aids the biosynthesis of collagen, L-carnitine and some neurotransmitters, as well as playing a role in protein metabolism.

There are a host of other benefits, from acting as an important antioxidant to boosting your natural immunity, so this is one to consider for your new supplement spread.

Our The Tone Capsules also include vitamin C alongside a host of other beneficial nutrients - just sayin…

Vitamin D

 Vitamin D is important in a lot of ways, but especially for our bone health, immune function and – perhaps most famously – mood regulation.

Unfortunately, if you’re in the UK you’re almost certainly deficient in this as we get most of our vitamin D from the sun. Even if you’re lucky enough to live where the sun shines regularly, keeping your vitamin D levels topped up can make a significant difference to how you feel every day.

This is one to get on the list ASAP.

Omega-3 (Fish Oil)

Fish oil may not sound like the most appetising to start your day with, but many people can be deficient in omega-3 fatty acids for a few reasons. If you don’t eat much fish or are pregnant/breastfeeding, it can be a good idea to top up on this one.

Studies have shown that omega-3 may support heart and eye health, reduce inflammation and help treat mental decline and certain mental health conditions.

Probiotics and prebiotics

Probiotics and prebiotics are quite a hot topic at the moment, with their impacts on gut health a major point of interest.

Our gut microbiome is essentially our gut’s ecosystem – bigger than the average human brain and containing trillions of bacteria. As such a complex beast, it doesn’t take much to throw it off. Regularly taking pro- and pre-biotics can help to maintain the natural balance of your gut microbiome which can play a big role in not just our gut health, but our wider health, too.

Did you know, our gut is often called our ‘second brain’ – it’s that important. A misbalanced gut microbiome can lead to all sorts of problems, from digestive symptoms all the way to mental health issues. In fact, our gut produces around 95% of our body’s serotonin (the ‘feel-good’ chemical), so it’s crucial to get this one right.

Pro-and pre-biotics work together (pro-biotics work to strengthen your ‘good’ gut bacteria, and pre-biotics act as food for the pros) – so make sure you’re striking a good balance.

Looking for an easy way to get both of these into your diet more regularly? Check out our The Digest Capsules.

Calcium 

Calcium is super important for your bones, but also your heart, muscles and nerves. Most adults need around 700mg per day, which is usually doable within a normal diet.

However, if you follow a vegan diet, are lactose intolerant or don’t consume dairy, you might be falling short of your daily requirements. If so, a calcium supplement can be a great choice to support your general health.

Magnesium

Magnesium is an easy one to overlook when considering the best supplements for your health, but it offers some pretty significant benefits.

Every cell in your body needs magnesium to function, so it’s pretty important stuff. Magnesium can help to regulate your blood sugar levels, benefit athletic performance, support better sleep, promote heart health and even help to fight depression.

Studies have shown that a high proportion of the UK population are deficient in magnesium too, so this is another important one to top up on. 

Iron 

Iron is another common deficiency manner suffer from, in the form of anaemia. However, supplementing iron isn’t only beneficial for those significantly deficient in it.

A study evaluated iron supplementation and found that even for those not fully deficient in it, self-fatigue was significantly reduced. Iron is vital for energy production, oxygen transportation and the immune system, so it makes sense that supplementing this will help your body to run more efficiently and provide you with more energy.

If you’re looking for peak performance, our The Rise Capsules contain iron and a bunch of other energy-boosting nutrients to keep you firing on all cylinders

Protein

To wrap it all up, let’s talk protein.

Protein is one of the most invaluable nutrients found in the body. It acts as the building block for tissue to repair damage, provide you with energy and strengthen every aspect of your body – from your muscles and skin to your hair and nails.

On the whole, UK citizens are pretty good at hitting their required protein intake, but if you’re looking for gains, you might be searching for a simple way to level up your protein game. Innermost offers a range of protein-packed products with a host of other nutritious goodies found in them, too. Add one of these to your daily routine and give your body more of what it needs.

What supplements should I take?: your daily drivers 

Finding the right mix of supplements for your own individual needs can be a challenge, but hopefully this guide offers you some insight into which are the most important supplements, and which ones you might personally benefit from most.

There are many other supplements and nutrition products on the market to consider, but if you use these as a baseline, you’ll be on your way to feeling and looking your best in no time.

Check out our range of capsules and proteins to find an easy way to boost your daily nutritional intake.

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
