Best All-in-One Protein Powder UK

What was once thought of as a useless by-product of cow’s milk is now considered the best protein source on the planet. I am, of course, talking about whey protein – the most used bodybuilding supplement in history.

All in One protein powder take the mighty whey protein and combine it with other ingredients, such as creatine, carbohydrates, BCAAs, vitamins, and minerals. These synergistic formulas provide a full spectrum of nutrients in one shake to help maximize muscle growth and speed up post-working recovery.

It’s a great idea to take what would be several individual supplements and combine them into one shake. But now you face the problem of finding the best all-in-one whey protein powder, as some are better than others.

Well, I have good news, we’ve taken the hassle out of shopping for an all-in-one protein by shortlisting the top 5 most effective.

1. Reflex Nutrition One Stop Xtreme

Reflex Nutrition is one of the UK’s best supplement brands. The wide array of exceptionally high-quality products has most certainly earned them this title.

This statement is no better reflected than in their flagship all-in-one supplement – One Stop Xtreme.

First and foremost, One Stop Xtreme contains the finest whey protein that comes from grass-fed cows, which naturally contains higher levels of Omega-3 and CLA. The carbohydrates are from organic oats and barley, making this suitable as a meal replacement shale, too.

A specially formulated Muscle & Strength stack is blended into this supplement, containing Creapure – the highest quality creatine monohydrate available – BCAAs, free form L-Leucine (the most potent muscle-building amino), Glutamine Peptides, and Beta-Alanine.

Also, a TestoFusion Stack containing chelated minerals Zinc, Magnesium, and Avena Sativa, for the healthy promotion of testosterone production – the hormone that not only builds muscle, but impacts bone density, mood, and sex drive. Anything that helps you secrete more testosterone is a good thing.

Friendly bacteria and digestive enzymes are also added for gut health and absorption of nutrients. For those of you who don’t know, friendly bacteria assist the body with numerous tasks, one of which is gut health. Poor gut health can be the cause of numerous issues, friendly bacteria can help resolve this. As for the digestive enzymes, let’s just say, these enzymes will help the product become more easily absorbed in the body.

2. Bulk Powders Aftermath

Bulk Protein All in One Aftermath

Nutritional Stats, per serving of 70g scoops:

  • Kcal: 226
  • Protein: 40g
  • Carbs: 21g
  • Fat: 2.1g
  • Includes Whey Isolate as primary protein, Pure Creapure creatine mono, Glutamine Peptides, HMB, and Leucine.

Bulk Powders have done an amazing job at formulating and manufacturing their own all in one post working supplement. Its mTOR Protein Complex consists of whey isolate as the primary source, and additional whey concentrate to deliver 40g of quality protein per shake.

It’s super low in sugar, with just 0.7g. This is achieved by using Vitargo as the main source of carbohydrates, which uses barley starch in a patented process to produce a rabidly absorbing pure carbohydrate.

Blended with these nutritious macronutrients are Creapure Creatine Monohydrate, Glutamine Peptides, and HMB, to increase performance and build more muscle from each workout.

With the large black and green packaging, and with this being part of Bulk Powders Pro Series, it looks pricy. Bulk Aftermath is a surprisingly affordable all-in-one protein and creatine supplement, providing a premium formulation that fits most budgets.

I’ve drank the double chocolate flavour and it’s really nice, and mixes to a smooth consistency, without lumps. Chocolate is always my favoured choice with shakes, but everyone is different. The thing that will flavour is that opinions vary – some reviews say that vanilla is better than chocolate, and vice versa. Bulk powders put months of work into taste testing, and from the feedback, it will like across all tastes.

Informed Spot is Accredited and completely transparent with ingredients, this is an ideal choice for professional athletes and bodybuilders.

3. USN Muscle Fuel Anabolic

USN Muscle Anabolic all in one mass gainer

Per serving, 2 scoops totalling 150g:

  • Kcal: 564
  • Protein: 55g
  • Carbs: 77g
  • Fat: 3.2g
  • Includes: 3g L-Leucine, Creatine monohydrate, ZMA, and Aminogen. Vitamins A, D, E, C, B12. Green Oats and Tolerase™ L.

You’ve probably heard of USN, they’ve made their way into a lot of the big chain supermarkets like Asda and Tesco. A mainstream supplement brand with a solid line of sports nutrition supplements, this company takes a scientific approach to its product formulations. It’s used by professional athletes and competitive bodybuilders in the UK and around the world.

So, what does their all-in-one supplement, Muscle Fuel Anabolic have to offer?

As with the others on this list, let’s start with the protein source and dose, as this is the primary muscle-building component of an all-in-one powder. They’re using a blend of whey protein concentrate, soy protein isolate, hydrolyzed wheat protein, egg albumen, and milk protein concentrate.

Now, these are cheaper protein sources than pure whey isolate, that’s why you need 150g over 2 large scoops to hit the 55g of protein per shake. Although these proteins cost less and likely give USN good margins, their selling point is that they provide a multi-stage time-release protein matrix across 5 protein sources.

USN claims that this mix of protein sources provides fast, medium, and slow-digesting proteins to give a steady release of muscle-building amino acids over 9 hours.

USN Muscle Fuel Anabolic has a considerable 77g of carbs, of which 26g is sugar. It uses plain dextrose and maltodextrin, which does the job of delivering carbs, but oats would be a more desirable ingredient to use.

It accompanies a high carb – high protein ratio. We all know the importance of protein consumption and how it builds and maintains muscle tissue. Even those who aren’t well-versed in bodybuilding or fitness know this. Contrary to popular belief, carbohydrates are also not just a useful fuel source but indirectly help with muscle mass, too. They provide and restore the fuel our muscles need for an intense training session. These two factors are an extremely anabolic recipe!

This new USN all-in-one powder contains ZMA – zinc, magnesium aspartate, and vitamin B6. This combination of vitamins and minerals is widely known in the bodybuilding world for its effects on both testosterone and performance. Consistently taking ZMA may help improve testosterone levels which will encourage the growth of muscle mass. This combined with an increase in energy levels makes this product extremely beneficial.

4. PhD Synergy ISO-7 all-in-one Protein

PhD Synergy all in one muscle gain formula

Per serving, 2 scoops:

  • Kcal: 253
  • Protein: 40g
  • Carbs: 17g
  • Fat: 2.5g
  • Includes: Potent mix of 5g of creatine, Peptide bonded Leucine, Zinc, Magnesium, rich amino acid profile, and Vitamins C, and B6.

There’s a reason why PhD’s products can be found in your local supermarket, it’s because they are a well-trusted brand that produces quality innovative supplements. They not only produce high-quality products but have been around for a long time. In fact, PhD – Synergy ISO-7 has been around since 2006 – which is a testament to the effectiveness and popularity of this all in one.

Their all-in-one protein powder – synergy ISO-7, is not only comprised of premium ingredients but has an impressive spectrum of well-thought-out nutrients – ideal for post-workout recovery.

This was my staple post-workout shake for many years, before switching to Reflex, but I still use this from time to time, as it’s truly an excellent anabolic all-in-one protein powder. I attribute a lot of my best lean muscle gains to the regular use of this supplement.
Its high 40g protein content (which is the optimal dose for maximizing protein synthesis) comes from a blend of whey concentrate, Hydrolysed Wheat Protein, and Micellar Casein.

It mixes really well into a smooth shake with water or milk, and for such a low carbohydrate content, it’s one of the best-tasting all-in-one protein powders I’ve had the pleasure of drinking. Perhaps the blend of high and low-digesting carbs coming from Ground oats, Maltodextrin, and Dextrose Monohydrate are what help with the taste.

Because of its great taste and texture, high protein punch, and intelligent profile of ingredients, this was my go-to all-in-one for years. I still highly rate and recommend this supplement to this day.

5. My Protein All-in-One Perform Blend Elite

MyProtein Perform Shake

Per serving, 2 heaped scoops:

  • Kcal: 236
  • Protein: 30g
  • Carbs: 22g
  • Fat: 2.6g
  • Includes: Creapre creatine and HMB

When it comes to the top 5 all-in-one protein blends, it isn’t surprising that My Proteins all-in-one made the list. This award-winning company was founded in 2004 and has grown to become a household name in the fitness industry.

Their products are designed and manufactured in-house to the highest standards by a team of experts. Let’s talk about what they’ve done with their all in one protein formulation.

First, they use a mix of Whey Protein Concentrate and Whey Protein Isolate that provides a good 30g of protein per shake.

Carbs come from a mix of Dextrose, Ground Oats to provide 22g, of which 15g are sugars. A little higher on sugar compared to others on the list.

This product contains HMB. HMB is an ingredient not commonly added and or utilized for muscle growth and repair but yet the benefits these key ingredient offers are precisely what makes this product so unique. HMB – (beta-hydroxy-beta-methylbutyrate) is naturally produced in the body and studies done on supplementation state that it may help boost protein synthesis whilst simultaneously lowering muscle breakdown.

The fact of the matter is, that not everyone is going to enjoy a protein shake. Some might prefer a more sugary drink whilst others may not. Everyone on this planet is different and therefore, not everyone will like this product. However, the collection of positive reviews all make notes on the flavour. More specifically, the flavour of this product seems to be the most well-enjoyed aspect of this product making it more likely that you will enjoy it too!

If you are inexperienced in this area, knowing and understanding what to look for in a product can be hard. Not only is this aspect challenging but choosing the right company to make your purchase from is too. Luckily for you, my protein is a brand you can trust, they not only provide delicious products but quality-assured products!

Choosing an All-In-One Protein Powder

When choosing the perfect all-in-one protein supplement for your training goals, there are a few factors to consider.

Taste – You may be a chocolate guy or girl – that’s my go-to flavour. However, some brands of chocolate shakes taste horrible, so you’d need to do some testing. A lot of supplement brands have small samples to try first, before committing to a large 5kg tub or bag. Always test taste and texture, because there’s no point in dreading your morning or post-workout shake, it should be something that goes down easy.

Cost – Supplements can be expensive, especially when it’s an ongoing expense each month. Buying a cheaper option doesn’t always mean that the ingredients are of less quality. As you can see from our list, there is high quality, and very affordable all-in-ones available.

Ingredients – Are you looking to bulk up? Then you might want to look for high carbs and high-calorie shake that contains creatine. Maybe you’re looking to stay lean, in which case you’d want to look for CLA and a shake that contains low GI carbs. There are various formulas, some containing vitamins and minerals, and have a good read over the nutritional profile and ingredients before buying.

On a brighter note, if you are looking for a top-notch all-in-one protein product, look no further than those recommended above. The companies that produce and sell these products have been well-known in this industry for many years and they’ve been hand-picked, by me – a bodybuilding supplements expert with 19 years of experience.
