The Most Essential Weight-Lifting Supplements

If you’re working hard lifting weights at the gym, chances are you want to see the best outcomes you possibly can. Regular, consistent exercise is key to achieving results, but sometimes, progress can feel slow and frustrating. That’s where workout supplements come in. 

Research has observed that performance supplements have helped significantly improve the effects of weight training, making them a must-have for anyone looking to kick things up a gear. 

With a variety of supplements on the market, with the potential to optimise your muscle growth, boost your physical performance, and increase your stamina, knowing where to get started can be pretty confusing. 

That’s why we’re here to show you the best of the best. 

What Is the Best Weight-Lifting Supplement for You?

These sports supplements can help you in a number of ways, so it’s a good idea to pinpoint your needs to figure out which will be the best for you. 

Are you looking to increase muscle growth? Achieve more sets and reps? Reduce post-workout fatigue? 

Some of these supplements can help in all of these areas, while some specifically target a certain benefit. Whatever you need to improve, you’re sure to find something here.

Creatine Monohydrate


  • Boost muscle growth 
  • Improve athletic performance
  • Optimise weight training  
  • Accelerate exercise recovery 

Creatine monohydrate is one of the most popular supplements in the weightlifting world, widely believed to be the most effective product on the market! Research has indicated that creatine can help build muscle, enhance physical performance, and boost cognitive function. 

Creatine allows your body to produce ATP, a vitally important nucleotide that acts as fuel for your cells, giving you energy and helping you synthesise proteins. 

It’s no wonder, then, that regular supplementation has been shown to help improve weightlifting performance by up to 45%. Studies have found that creatine increases muscle fibre growth by 2-3 times, when compared to exercise alone. 

Creatine can also improve the appearance of your muscles by drawing water into your cells! 

If you’re looking to start bulking up fast, creating monohydrate is a solid choice. 

Suggested Use: Take 4 capsules a day with a glass of water.

  • Optimise muscle gains 
  • Improve athletic performance 
  • Promote weight loss 
  • Speed up recovery

When many people think of weight-lifting supplements, one of the first things to spring to mind is anabolic (muscle-building) steroids. These illegal supplements might be powerful, but they come with some nasty, unwanted side effects. 

But what if there was a legal alternative? 

Turkesterone is an ecdysteroid that is found naturally in plants. Like steroids, it is anabolic, meaning it can help your body build muscle tissue. However, as turkesterone does not attach to your androgen receptors, you won’t get any of the steroidal side effects like hair loss or acne. 

This doesn’t mean it’s any less effective in boosting your muscle growth – in fact, turkesterone has been shown to outperform anabolic steroids. Regular supplementation could help to increase protein synthesis by up to 20%

If you’re looking to kick-start your gains, turkesterone could be the helping hand you need. 

Recommended Usage: Take 2 capsules a day with a glass of water.

  • Increase muscle growth
  • Improve exercise recovery 
  • Prevent muscle wastage
  • Boost energy 

BCAA supplements have gained some major traction in the fitness world over the last few years, commonly used to promote muscle growth and enhance exercise performance. 

Your body needs certain essential amino acids to produce protein and muscle, but it cannot generate them on its own. That’s where branched-chain amino acid supplements come in! 

Containing three key ingredients, BCAA can give your body the building blocks it needs to grow. One study found that BCAA supplementation helped to increase muscle protein synthesis by 22% after a resistant workout session, increasing muscle growth. 

Ensuring you have enough of these amino acids also means your body will have the compounds it needs to repair your muscles following a workout, preventing muscle degradation and improving recovery times

If you’re looking to promote steady, lean muscle growth, BCAAs are the way to go. 

Suggested Usage: Take 2 capsules a day with a glass of water. 



  • Enhance athletic performance 
  • Boost power during training 
  • Improve weight training sessions 
  • Promote muscle growth 

Citrulline is a naturally occurring amino acid vital to healthy body function. A building block of proteins, citrulline has become a staple in the weightlifting community for its performance-enhancing properties. 

Citrulline is a precursor to arginine, which your body uses to build muscle. Increasing your arginine levels also raises the levels of nitric oxide in your blood. This relaxes your blood vessels and improves your blood flow, allowing more oxygen and nutrients to be delivered to your muscles. 

By helping give your muscles more fuel during exercise, citrulline can help significantly boost your power output. This increased blood flow – along with improved muscle energy metabolism and mitochondrial respiration – could allow you to significantly improve your performance during weightlifting sessions, achieving more reps

There are two primary variants of this supplement on the market: L-citrulline and citrulline malate. Some users prefer L-citrulline, believing it to be a purer form, while others believe malate allows for better bioavailability and absorption. 

If you want to dramatically improve your weight-lifting performance, citrulline should be your go-to.

Suggested Use: Take 2 capsules a day with a glass of water. 



  • Accelerate post-workout recovery 
  • Reduce fatigue 
  • Boost muscle growth 
  • Support a healthy immune system 

L-glutamine has become one of the most prized supplements in the weightlifting world thanks to its ability to improve post-exercise recovery time, repair damaged tissue, and reduce fatigue. 

One of the most important amino acids in your body, glutamine is used to form proteins and support the immune system. When you undertake regular heavy exercise – like strength or resistance training – levels can rapidly get depleted. 

Glutamine supplements provide your body with the essential building blocks it needs to repair and grow the muscles after exercise. Research has found that glutamine can help improve recovery times and significantly reduce muscle soreness

L-glutamine has been linked to muscle growth, but most use it for its potent recovery effects, which can help you stick to your workout routine. When paired with a powerful muscle-booster like creatine or BCAA, glutamine could help you achieve some staggering results. 

If you want to adhere to your weight-lifting regime and avoid burnout, L-glutamine is the way to go. 

Suggested Use: Take 2 Capsules a day with a glass of water.

  • Boost muscle growth 
  • Accelerate weight loss 
  • Prevent muscle loss 
  • Improves physical wellbeing 

If you’re in the cutting phase of your weightlifting workout routine, lysine is a great companion to have on your side. 

When you’re cutting, the aim is to lose weight while maintaining or growing muscle. It’s key that you lose weight by burning the right sources of fuel – and not your hard-earned gains

This is where lysine comes in. An essential amino acid that the body cannot produce itself, lysine plays a vital role in your body, used to build muscle while helping to lose fat. 

Lysine is involved in protein synthesis, helping you to achieve muscular hypertrophy for bigger muscles. It also encourages and stimulates muscle growth while helping prevent muscle degradation, which can occur when you workout on a calorie deficit. 

Also used to transport fatty acids through to your cells so that they can be burnt for energy, Lysine could help you to lose weight quicker. Targeting fat cells for energy is key for cutting, helping to prevent any muscle loss. 

If you want to achieve some great definition during your cutting-phase resistance training, L-lysine is a must-have. 

Suggested Use: Take 2 capsules a day with a glass of water.

Adding Weight-Lifting Supplements to Your Routine

Most weight-lifting supplements come in a powder form and require you to take them at specific times of day. If you’re taking multiple supplements – which many gym-goers do – this can quickly become confusing.

To get the best results, take your supplements alongside a healthy, well-balanced diet and a consistent workout routine.
