While regular exercise and a balanced diet should be enough to make progress at the gym, sometimes it can feel like you’re just not getting anywhere.
This may be because it’s hard to hit your daily targets of nutrients that are vital for muscle growth and improved performance – which is where supplements come in.
“To see the most effective marginal gains from supplements, they should be incorporated into an already nutrient-rich diet,” says Rachel Butcher, Head of Nutrition at Third Space London. “Assuming your basic diet is on point, though, supplements may have a place when used appropriately and you are informed on what they can do and what their limitations are. When thinking about incorporating a supplement into your regime, consider why you want to include it and therefore whether you should.”
What supplements should I consider for the gym?
There’s a seemingly endless selection of supplements on the market. You only need to scroll on TikTok and you’ll see fitness influencers promoting different hacks and products that are supposedly great for the gym, so it can be hard to know what’s actually best – so we’re here to break it down.
Since protein is key to repairing muscles, it’s the most common supplement for those looking to build – and it’s proven to work: “There is robust evidence which shows that consuming protein pre- and/or post-workout induces a significant rise in muscle protein synthesis,” says a 2018 report.
“I’d recommend a whey protein isolate for the clarity in the product - it’s clean and easily digestible into the body,” says personal trainer and founder of Achievable Academy, Alex Beattie. “Also creatine monohydrate and omega 3 would be my go-to's. If you’re doing cardio like running, I’d look at electrolytes, too, to aid hydration.”
For Butcher, the best supplements are essential nutrients which are difficult to come by through diet alone: “Examples of this would be creatine and vitamin D – in the absence of sufficient daily sunlight – and beta-alanine. All are present in small doses in certain meat, fish and dairy products, but not enough to obtain the amounts needed to support health or performance.”
“When you either don't like, or prefer not to, include certain food like key omega 3s, EPA & DHA, it can be a good idea to incorporate these nutrients in supplement form,” says Butcher.
The good news? It’s never been easier to up your intake. With a vast selection on the market that spans powders, gummies, bars and tablets, there’s a world of gym-friendly supplements which deliver results.
How often should I take supplements?
Consistency is key: “If you’re going to use supplements, they need to be used regularly, but not to replace food,” says Beattie.
Butcher’s top tip? “Habit stack your routines. The best supplement routine is one you can stick to consistently, so timing your supplement taking to an already formed habit, like brushing your teeth, maximises your chances of keeping up your habit regularly.”

Bulk Pure Whey Isolate 500g
Bulk is one of the leaders in supplementation in the U.K. With athlete ambassadors such as Anthony Joshua on its roster, you know its products are going to work.
For maximum gains, this one’s for you. Firstly, the mammoth 24g of protein in each serving is not only staggering, but it comes from grass-fed cows too, which means it’s 100 per cent free from hormone and genetic modifications - now that is clean. It also mixes well, but, for us, we preferred it with less water for a consistency that’s just right.

MyProtein Impact Whey Isolate
Isolate protein powders are by far the best when choosing whey, as it’s simply a refined form. Naturally, it only suits those who aren’t dairy-intolerant or vegan as it’s derived from milk, but the protein content is next level.
MyProtein’s Impact Whey Isolate comes in with a massive 90 per cent protein content, with almost zero carbs or fats, which means it’s an all-around brilliant protein supplement. At the lower range price point, it’s good for those just starting out, and it mixes well so it’s nice to drink on its own, too.

Optimum Nutrition Gold Standard 100% Casein Powder Strawberry
While whey protein is thought to be better than casein when it comes to muscle growth, some people prefer casein for its slower digestion process. Optimum Nutrition’s Gold Standard 100% Casein Powder comes in a delicious strawberry flavour and is best for slow-digesting protein support between meals and before bed.
Sometimes slower is better - especially when it comes to the rate of protein digestion. While rapid protein absorption is ideal right before or after exercise, delayed release is probably more beneficial throughout the remainder of the day and especially last thing at night.

PhD Smart Protein Plant Chocolate Cookie
Don’t listen to anyone who says vegans can’t build muscle. In fact, some of the best protein powders are made from vegan protein powder. They’re also a great option for those who may struggle to digest whey protein but still want to enjoy protein powder’s muscle-building qualities.
PhD’s Smart Protein Plant in Chocolate Cookie is one of the best vegan protein powders around and packs 20g plant protein per scoop. It’s also exceptionally low in sugar: containing less than one gram per 25g serving. Perfect for adding muscle but not fat.

Myvitamins Protein Gummies
Convenience is key when it comes to protein. There’s not always time to make a shake - especially if you prefer to use milk which isn’t available unless you have a fridge to hand.

There are only 10 grams of protein in each gummy, so you can enjoy a dose of the peachy goodness up to eight times a day.

Kinetica Lean Protein Powder
For best results, you’ll probably want to separate your muscle growth (bulking) and weight loss (shredding) into separate stages. But, if you’re hoping to build muscle while dropping fat at the same time, a low-calorie protein powder will come in handy. Kinetica’s Lean Protein Powder offers 16g of protein per 25g scoop and contains green tea extract for added wellness. Each scoop is also only 97 calories, making it lower than most whey proteins around.
