The best supplements for men

Take the best sports nutrition products in the right doses and at the right time to accelerate fat loss, increase lean muscle and get stronger. Then these best supplements for men will help you look, feel and perform at your very best, says New Body Plan editorial director Joe Warner

Over the years, in pursuit of a bigger, stronger and leaner body, I’ve tried practically every single sports nutrition supplement you can name. Twenty years ago, when I first started lifting weights, the supplement options were stark: mail order whey protein powder that tasted so foul that getting it down my neck was always the toughest part of every workout.

Today things are very different. Go online or into any supermarket and you’ll find rows of energy-boosting gels, pre-workout powders, muscle-pumping pills, cognitive-enhancing capsules, protein-pimped water, and even tummy-tightening tea bags, and much more besides. Indeed, whatever your health and fitness goal I’d wager that there’s a supplement promising to deliver the result you desire.

How I lost 10kg of fat in 8 weeks (and 7 ways you can too!)

But how do you know which supps work and will help you look, feel and perform at your best? Or which are a complete waste of your money? Like those “fat-loss” formulas that are essentially over-priced laxatives. So you’re both figuratively and literally flushing your hard-earned cash straight down the toilet.

I’ve written this guide to supplements so you can understand which products can help you build the body you want – alongside a smart and structured training programme – in the fastest-possible time. Below you’ll find my overview, plus pros and cons, of the most common and popular products, so read on to discover what you might need to help you build the leaner, bigger and stronger body you want!

The 7 best supplements for men

Whey protein powder

What? Whey is a by-product of the cheese-making process and is the liquid left over once milk has been curdled and strained. It can then be dried into a powder, and whey protein powder is one of the most popular sports nutrition products in the world. Why? Because it’s very rapidly digested, so it gets to your muscles very quickly after training to repair the muscle damage caused to make your muscles bigger and stronger.
Why? A whey protein shake, made with cold water or milk, after training will flood your bloodstream with amino acids (the building blocks of protein). They are then quickly shuttled into your muscle cells where they are laid down as new muscle. Here’s our guide to the best protein powders to build muscle.

-Rapidly digested after training
-Easy way to increase protein intake
-Sweet taste to kill any sugar cravings

-High-end brands can be expensive
-Can cause bloating and excess gas
-Not suitable for lactose intolerant

Rating: ⭐️⭐️⭐️⭐️★

Instant Insight
Whey protein powder is a smart supplement investment if you want to quickly and easily increase your daily protein intake to add lean muscle mass fast.

2 Omega-3 fish oil

What? Omega-3 is an essential fatty acid. That means that your body can’t manufacture it so you need to consume it from your diet or through a supplement. Omega-3 is found in high concentrations in oily fish, especially those that live in colder waters.

Why? Omega-3 is very important for healthy metabolic function. Adequate intake provides a whole host of other health benefits, including reducing the risk of cardiovascular disease, certain cancers, mental health disorders and inflammation.
 If you don’t eat the recommended two portions of fish per week – one serving of white fish, such as cod, and one serving of oily fish, such as salmon – then you should consider an omega-3 supplement (and take it with food to limit the “fishy” taste repeating on you). That’s why we rank omega-3 as one of the best supplements for men.

Proven brain health benefits
Reduces inflammation
Can aid weight-loss efforts

Doesn’t taste very nice
Fishy taste can repeat on you
Not suitable for vegans or vegetarians

Rating: ⭐️⭐️⭐️⭐️★

Instant Insight
Omega-3 supplementation can provide multiple mental and physical health benefits if you don’t eat high-quality fish very often.

3 Pre-workout supplements

What? Pre-workout products are designed to be taken ahead of your training session because they contain a combination of compounds intended to improve focus, performance and energy levels, as well as better blood flow to deliver oxygen and nutrients to your muscles faster. The key ingredients typically include caffeine, the amino acids beta-alanine and arginine, and creatine, but many ingredients may be present.
Why? Research supports claims that caffeine improves focus and concentration, and many people say they get a superior muscle “pump” during training because of increased blood flow. A pre-workout can also provide a psychological boost as part of a pre-training ritual that fires you up so you consequently perform better. However, you should always test a product with a small sample before trying a full dose to ensure you don’t suffer any adverse reactions.

-Will improve focus
-May increase muscle pump
-Can boost energy levels

-Beta-alanine can cause skin tingles or itches
-Caffeine too late in the day can disrupt sleep
-May contain many artificial ingredients

Rating: ⭐️⭐️⭐️★★

Instant Insight
Pre-workouts taken at the right time can improve workout performance, but not all products work for all people so some trial and error may be required.

4 Vitamin D

What? Vitamin D is a fat-soluble vitamin-like compound that plays an essential role in a huge number of biological functions, as well as improving cognition and reducing the risk of certain cancers, cardiovascular disease and dementia. It is sometimes known as the “sunshine vitamin” because it is produced by your body when your skin is exposed to direct sunlight, but is also found in low doses in some foods, such as fish and eggs.
Why? If you live in the UK, or other higher-latitude parts of the northern hemisphere, then the chances are that you will have some level of vitamin D deficiency. One study found more than 50% of the UK adult population have sub-optimal levels because there isn’t enough strong sunlight for much of the year to make production possible.

Essential for brain health
Crucial role in hormone production
Vital for muscle and bone health

Taking too much can be toxic
Better absorbed when taken with food
Can lower levels of vitamin K

Rating: ⭐️⭐️⭐️⭐️⭐️

Instant Insight
If you live in high-latitude countries then you may suffer from sub-optimal vitamin D levels for around half the year so supplementation can reduce your risk of a deficiency.


What? Branched-chain amino acids (BCAAs) are a combined form of three of the nine essential amino acids: leucine, isoleucine and valine. They are called “essential” because your body can’t manufacture them. That means they must be obtained through the food you eat, or through a sports nutrition product. That’s why we rate them as one of the best supplements for men.
Why? Research is fairly conclusive that BCAA supplementation before, during and after training can help induce muscle protein synthesis (MPS), which is the technical term for the process that lays down new muscle tissue that makes your muscles bigger and stronger. BCAAs also improve muscular endurance, increase energy levels, and reduce recovery time. High use of BCAAs can deplete levels of other nutrients, especially the B vitamin B6, so choose a product that also contains these vitamins or take a daily a multivitamin.

Inhibits muscle tissue breakdown
Encourages muscle protein synthesis
Shortens recovery time

Can deplete levels of vitamin B6
May contain many artificial ingredients
No substitute for high-quality protein-rich foods

Rating: ⭐️⭐️⭐️★★

Instant Insight
BCAAs can be a cheap and tasty way to improve gym performance, increase muscle mass growth and speed up the recovery process.


What? Creatine is an organic compound that exists naturally in the body and is instrumental in providing energy to your cells. It is not an essential nutrient because your body can make it from other compounds (two amino acids: glycine and arginine), but it can also be consumed through certain foods. Red meat, such as steak, is naturally high in creatine.
Why? Taking a creatine supplement will increase your body’s natural levels, which is why it’s one of our best supplements for men. Research has shown that supplementation can improve physical performance, especially during high-effort exercise, such as weight lifting or high-intensity interval training. Why? Because creatine enables your muscles to work harder for longer. Always take creatine with plenty of water to avoid dehydration. Some people benefit from taking it with food to prevent stomach upset or discomfort.

Increases your cells energy stores
Improves performance during intensive training
Makes muscles look and feel bigger

Causes water retention
May cause stomach discomfort
Can cause muscle cramping

Rating: ⭐️⭐️⭐️⭐️★

Instant Insight
If you want to build muscle mass faster then creatine can help but water retention can make the body look “softer” and less defined during periods of supplementation.

Zinc and magnesium

What? Zinc and magnesium are two of the best supplements for active men. Why? Because both are essential trace elements that are have a huge number of biological roles. Zinc is involved in DNA metabolism, testosterone production, brain health, and efficient central nervous system function. And every single cell in your body needs magnesium ions to produce energy. Shellfish and red meat, especially beef, lamb and liver, are the best dietary sources of zinc. Magnesium is found in nuts, leafy greens and whole grains.
Why? Research suggest that most Western adults fail to hit the daily recommended target of both minerals through diet alone. And increasingly poor soil quality due to over-farming means that produce is now less nutrient-dense than a generation ago. Zinc and magnesium are even more important if you exercise. Why? Because levels of both elements are depleted through training. Zinc is lost through sweat, and magnesium is needed for central nervous system function and muscle contractions.

Zinc is heavily involved in testosterone production
Magnesium is needed to release energy in cells
Supplementation increases levels depleted by training

May cause nausea
Can cause stomach upset
May suppress copper and iron absorption

Rating: ⭐️⭐️⭐️⭐️★

Instant Insight
If you regularly train hard and sweat a lot, or don’t eat a lot of red meat or leafy greens, then supplementing zinc and magnesium could help optimise your levels.
