Do supplements work, or are you wasting your time and money? Let’s get clear on what actually drives results. In many nutrition sessions, people usually only want to hear and know one thing and one thing only: what supplement is going to help me lose weight? The thing is if there was one magic pill or something amazing on the market, don’t you think everyone would be taking it? There are no magic pills, but there are some supps we can take to enhance our performance as long as we’ve nailed the basics with our food.
Why Supplements Aren’t the Foundation of Results
The supplement industry is huge and growing fast, despite the fact that a lot of products don’t actually live up to the hype. Even large-scale research has shown that daily multivitamins don’t significantly reduce the risk of major diseases in generally healthy people.
The same goes for a lot of “performance” supplements. Fat burners, testosterone boosters, and many pre-workouts are heavily marketed, but often lack strong evidence or only provide tiny effects that don’t really matter in real life. The harsh truth is, supplements don’t drive results – your habits do.
Consistent training, a balanced diet, good sleep, and proper recovery will always outperform any pill or powder. Supplements can help on top of that, but they can’t replace it.
What Actually Matters Before You Take Supplements
If your goal is better health, fat loss, or performance, this is where your focus should be:
Your overall diet
You should know by now that food does a lot more than just give you calories. It provides protein for muscle repair, vitamins and minerals for overall health, and healthy fats for hormones and brain function. Whole foods also work together. For example, vitamin C helps you absorb iron, and fats help absorb vitamins A, D, E, and K. That’s something supplements can’t fully replicate. You will benefit a lot more from the supplements mentioned below if you nail your basic nutrition first.
Training consistently
You don’t need a perfect program – you just need to show up regularly. Strength training, running, walking, or whatever you enjoy, done consistently, is what drives progress. There is no point in starting something that you hate just because you think you should as it’s not sustainable and you will stop it quickly and give up easily. Instead, find something you enjoy even if it feels small and keep it up. Small steps make big results.
Sleep and recovery
This is probably my biggest downfall, but it is where results actually happen. Poor sleep impacts performance, recovery, hunger, and even injury risk. Aim for 7–9 hours where possible, and don’t overlook rest days and hydration.
Consistency over time
There’s no shortcut here. You’ve heard it before; Results come from repeating the basics over and over:(effort + consistency) × time = progress
What Supplements Are Worth Considering?
Once your basics are solid, some supplements can be useful—especially if they solve a specific problem.
Protein powder
Helpful if you struggle to hit your protein target through food—busy days, low appetite, or higher training demands. As it provides all amino acids (building blocks of muscle), it is a smart clover when it comes to protein intake to reap major benefits. It’s convenient, not a necessity.
Creatine
One of the most researched supplements out there. Taking creatine daily supports strength, power, and performance in high-intensity training. Safe, effective, and actually worth considering if you train regularly. Even if you are not a high intensity trainer, I believe everyone can benefit from it as studies show it has benefits on brain health and reveals strength.
Fish oil (Omega-3s)
Can support heart health, reduce inflammation, and help with recovery—especially if you don’t eat much oily fish like salmon or sardines. Chances are you are not eating 2 portions of oily fish each week, so it is definitely worth it.
Vitamin D
Commonly low, especially if you’re not getting much sun. Interestingly even those who often get sun, will not have huge vitamin D levels as sunblock can block vitamin D being absorbed in the skin. Getting enough vitamin D is extremely important for bone health, immunity, and overall wellbeing. This is one where testing and supplementing can make a real difference, and should be considered especially in the winter months.
What Supplements Don’t Really Work (and How to Decide)
This is where people waste the most money.
- Fat burners: mostly stimulants—might boost energy briefly but won’t meaningfully burn fat.
- Testosterone boosters: very weak evidence behind most of them.
- Pre-workouts: can make you feel more energised, but won’t fix poor sleep or lack of effort. I prefer to just take a coffee!
A lot of these rely on marketing, not results. Unfortunately, the media has a way of making us believe that they will work. Have your money and buy some veggies instead!
How to decide if you need one
Before buying anything, ask yourself:
- What problem am I trying to solve?
- Can I fix it with food, training, or sleep first?
- Is there strong evidence behind this supplement?
- Am I already consistent with the basics?
- Should I book a consultation first with Authentic PT’s in-house nutritionist first? (Probably, yes)
If the answer to that second last one is no, consider the last one!
Final Thoughts: Do Supplements Actually Work?
Do supplements work? Only when the basics are already in place.
Supplements can be helpful, but they should support your routine, not be the focus of it.
The real results come from the ‘boring’ stuff; showing up to training, eating well most of the time, sleeping properly, and staying consistent.
That’s what actually sets the results, you just need to stick with it and trust the process!
