The best post-workout supplements of 2023
Best unflavoured creatine
Description
If you're not a fan of flavoured creatine and want to create your own post-workout concoction - MyProtein's pure unflavoured creatine is the way to go.
Easy to mix, a ton of servings and made with high-quality ingredients - MyProtein's unflavoured creatine is perfect to use throughout the day, but it works especially well after a tough strength session.
Our advice, however, would be to take two servings rather than the admittedly small 3 grams of creatine suggested by MyProtein.
Pros
- A great number of servings

Cons
- Not a lot of creatine per serving
Best whey protein powder
Description
As fitness fanatics, we couldn't bring ourselves not to include Optimum Nutrition's protein powder.

What sets it apart is its commitment to purity, with minimal fats, sugars and carbs per serving.
Pros
- The absolute best-flavoured protein powder
- Packed with protein
- Also contains BCAA
Cons
- A small amount of servings per tub
Best post-workout supplement for energy recovery
Description
When training, the most overlooked supplement just has to be carbs. Many fitness enthusiasts steer clear of carbs because of their infamous weight-gaining capabilities, but not all carbs are bad for you.
Cyclic dextrin carbohydrates are highly branched, complex carbs that are quickly used up by muscles to fuel growth and replenish stores of glycogen for your next workout, making sure you truly give it your all in your future sessions.
Affordable, plenty of doses, a powerful and instant source of explosive energy - Applied Nutrition has made one of the greatest post-workout supplements on the market that's absolutely worth a try.
Pros
- Incredibly strong post-workout boost
- Great for muscle growth
- Can be taken before or after a workout
Cons
- Not suitable for users attempting to lose weight
Best BCAA post-workout supplement
Description
BCAAs are an essential amino acid that you can only get through food and supplements, but it is vital in building a strong, muscular physique.
While eating meat is a good source of BCAAs, for vegans and vegetarians, that option just isn't there. Enter, Iron Labs' BCAA - containing all the essential amino acids for huge gains or even the prevention of muscle loss (which can happen if you're daily routine isn't particularly active).
IronLab's BCAA capsules are great for regulating muscle growth and easing post-workout fatigue, they're easy to swallow, and the benefits are, while not immediately noticeable - definitely worth experiencing.
Pros
- Great for more enhanced muscle growth
- Excellent for vegans
- Can be taken throughout the day
Cons
- Not a huge dose

Warrior Creatine comes in various fantastic flavours that give you a tasty punch of energy while also aiding in your gains during rest days.
Creatine is also an incredibly versatile supplement and can be taken before or after a workout - so you're not taking tonnes of supplements at once.
Pros
- Powerful muscle growth boost
- Great flavours
- Can be taken any time of the day
Cons
- Best not mixed with other drinks

Best post workout protein snack
Description
Sometimes, getting enough protein in your meals is - to put it bluntly, a complete nightmare. Many foods with plenty of protein tend also to be full of salt, fat and an excess of carbohydrates (and not the good kind).
Grenade's high protein bar simply has to be one the best quick-fix protein supplements on the market right now, not only because of its whopping 23 grams of protein but also because of the great variety of flavours.
Low carb, low sugar, and incredibly filling - Grenade is known for its excellent supplements, but its protein bars just take the cake.

- Packed with protein
- A great alternative to protein shakes
Cons
- Some reviewers say the bars have a little bit of an aftertaste

- Low calories

FAQs
What's the best post-workout supplements?
While there isn't a definitive 'ultimate' post-workout supplement, there are definite stand-outs.
A personal favourite of bodybuilders and athletes for many years has been protein powder - simple, delicious, effective at huge muscle growth, it's really the ultimate power-up after a tough gym session.
Are post-workout supplements worth it?
Post-workouts are more than worth it - they're essential for healthy exercise and muscle gains. An increase in nutrients boosts muscular growth whilst also easing aches and pains - allowing you to jump into your next workout with ease.
What is the most important nutrient for post-workout?
There are many excellent nutrients that you can start to introduce into your workout routine to boost muscle growth and give yourself a much more comfortable rest day, but by far, the most important nutrient you need is protein.
Protein is absolutely crucial for muscle repair and growth simply because muscle is protein. When you train hard, you are putting muscles under stress and slightly damaging the tissue - these are known as micro muscle tears - which sound scary but are necessary for the process of muscle growth.
Your body repairs these muscle tears with the new protein you've consumed, among other nutrients, repairing the damaged muscle fibre and causing them to grow.
What else is important for post-workout repair?
Another post-workout nutrient that is crucial is carbohydrates - you may be surprised by this, but yes - not all carbs are bad.
While exercising, your muscles deplete their supply of glycogen - the body's stored energy used for intense activities. Once your workout is over, your muscles are largely depleted of glycogen, which is not only important for future gym sessions - it's also essential for muscle repair.
Another popular post-workout supplement is creatine, which is a naturally occurring amino acid. Many athletes take creatine post-workout to increase lean muscle mass and muscular strength - which appears to work more effectively after an intense session. Creatine is one of the most science-backed pre-workouts you can buy. It can also be used as a pre-workout due to its energising and endurance-promoting qualities.
Pale skin, fatigue and feeling thin nails are all signs of iron deficiency, if you have any of these symptoms, it might be worth trying to introduce some iron into your diet - here are the best iron supplements from across the web.
How do I prevent bloating after taking post-workout?
First, you should hydrate well, avoiding sugary drinks and food that would further increase bloating. Don't gulp water, instead, take small sips to avoid being even more uncomfortable. You may also be experiencing stomach issues in reaction to certain ingredients, we'd suggest potentially trying some alternatives or consulting your doctor.
