A GUIDE TO SUPPLEMENTS THAT ACTUALLY WORK
Walk into any supplement shop or scroll online, and you’ll be hit with hundreds of products promising faster fat loss, more muscle, and better performance.
The problem is most of them aren’t necessary.
At Parlanti Fitness, the focus is always on the fundamentals first: training, nutrition, and consistency. Supplements are there to support your progress, not replace the basics.
In this guide, I’ll break down:
the supplements that actually work
what they do
when they’re worth using
and what you can safely ignore
1. Supplements Are Exactly That. Supplements
Before anything else, it’s important to understand:
Supplements are not the reason people get results.
Fat loss and muscle gain come from:
calorie balance
protein intake
structured training
consistency over time
Supplements can help, but only once these are in place.
2. The Supplements That Actually Work
These are the ones worth considering.
Protein Powder
What it does:
Helps you hit your daily protein target
Supports muscle recovery and growth
Keeps you fuller for longer
When to use it:
If you struggle to get enough protein through food
As a quick, convenient option (shakes, smoothies)
👉 This is one of the simplest and most effective supplements available.
Creatine Monohydrate
What it does:
Improves strength and performance
Supports muscle growth
Helps you train harder over time
How to use it:
3–10g per day
taken consistently (timing doesn’t matter too much)
👉 One of the most researched and proven supplements available.
Caffeine (Pre-Workout or Coffee)
What it does:
Increases energy and focus
can improve workout performance
When to use it:
before training
when energy is low
👉 Simple, effective, and often overlooked.
Vitamin D
What it does:
Supports overall health
helps with immune function
important for people in the UK with limited sunlight
👉 Worth considering, especially in autumn and winter.
3. Supplements That Can Help (But Aren’t Essential)
These can be useful in certain situations, but aren’t necessary for everyone.
Omega-3 (Fish Oils)
Supports general health
may help with recovery and inflammation
Magnesium
Can support sleep and recovery
useful if you struggle with sleep quality
Electrolytes
Helpful if you sweat a lot
useful during intense training or in hotter conditions
4. Supplements That Are Overhyped
This is where most people waste money.
Examples include:
“fat burner” pills
detox teas
extreme pre-workouts with dozens of ingredients
anything promising rapid transformation
These often:
have minimal real impact
rely on marketing rather than results
distract from what actually works
5. When Should You Start Using Supplements?
Only once your basics are in place.
That means:
you’re training consistently
your nutrition is structured
you’re hitting your protein target
you’re focused on long-term progress
If those aren’t sorted, supplements won’t fix the problem.
Common Questions About Supplements
Do I need supplements to lose fat?
No. Fat loss comes from a calorie deficit. Supplements can support the process, but they are not required.
Are supplements safe?
Most basic supplements (like protein, creatine, and vitamins) are safe when used correctly. Always follow recommended doses.
What’s the best supplement for beginners?
Protein powder is usually the best place to start, followed by creatine if you’re strength training.
Can supplements replace food?
No. Whole foods should always be your foundation.
Keep It Simple
You don’t need a cupboard full of supplements to get results.
For most people, this is more than enough:
protein powder
creatine
caffeine (if needed)
vitamin D (especially in the UK)
Focus on the basics first, then use supplements to support your progress.
