How it works
What is Justblitz?
Justblitz is a weekly subscription box that delivers frozen ingredient mix packs for daily smoothies designed to be a complete, balanced breakfast, nutritionally personalised to you. Our smoothies are delicious, quick to make, with real ingredients.
We recommend having a daily Justblitz smoothie as a healthier, more convenient breakfast. You’ll feel full, energized, and ready to go. However, our smoothies are flexible and can also replace lunch or dinner when you need a quick, nutritious option.
Convenience
The idea of starting the day with a healthy smoothie seems appealing but the reality is quite different. It takes time to find nice recipes, shop for ingredients, and painstakingly measure them out each morning. Justblitz takes care of the hard part for you. Each week, we measure out your recipe packs and deliver straight to your door. These packs are designed to be blitzed up straight from frozen, meaning you don’t have to worry about the hassle of preparation. Simply blend and enjoy a delicious, nutritious smoothie in minutes.
 
Complete Meal Replacement
Justblitz smoothies are not just a drink; they are a full meal. Each smoothie is carefully crafted to be healthier and more convenient than a traditional breakfast, lunch, or dinner. Packed with a variety of grains, vegetables, nuts, seeds, and superfoods, our smoothies provide all the nutrients you need to fuel your day. Whether you’re looking for a quick breakfast, a satisfying lunch, or a nutritious dinner, Justblitz smoothies have got you covered.
 
Personalised Nutrition
One of the standout features of Justblitz smoothies is the personalisation. Your smoothie mixes are tailored to your individual needs, ensuring you get the right balance of calories, protein, carbs, fats, and micronutrients. We take into account your body type, goals, allergies, and preferences to deliver a smoothie that is perfect for you. It’s like having a personal nutritionist in your kitchen every day.

Complete meals
Our smoothies aren’t just crushed fruits. They are designed to be complete meals, containing grains, vegetables, nuts, seeds, and superfoods.
 
Super nutrient dense
Unlike pre-blended bottled smoothies, which lose nutrients during pasteurisation, Justblitz smoothies are blended by you to preserve all their goodness for maximum daily health benefits
Drinking a freshly blended, nutritionally personalised smoothie daily provides your body with essential nutrients to support energy, focus, performance and long-term health. By swapping out your breakfast (or another meal) for a Justblitz smoothie, you’ll feel healthier, happier, and more energized to take on your day.
A smoothie lover with a chemistry degree who also happens to be a qualified nutritionist. We’re passionate about making healthy eating simple, enjoyable, and accessible for everyone.
Absolutely! I (Charlie, the founder) have mine as my lunch, not breakfast. I whizz it up in the morning, take it into work, stick it in the fridge and have it for lunch. It’s super cold by this time which makes it even nicer.
No, Justblitz smoothies are for everyone, not just sportspeople. While our smoothies are nutritionally personalised and can support & optimise athletic performance, they are designed to benefit anyone looking for a healthy, balanced meal option. They are great for those with busy lifestyles who still want to maintain a healthy diet or if you just want a simple way to be healthier long-term.
Yep. Why? Because for real benefit a daily smoothie should be a long-term habit not a sporadic event.
Our smoothie packs are delivered weekly. Box contains 5 to 7 packs, i.e. one for each day.
Store your smoothie packs in the freezer as soon as they arrive!
When you need to make your smoothie, take pack out of freezer, empty it into blender, add water (guideline amount on each pack)* and blitz! No need to defrost.
 
 
* or add milk, yoghurt, almond milk etc.! Whatever you like.
Absolutely. During the personalisation process you specify any dietary restrictions or allergies.
Because justblitz is a daily meal replacement. Replace any one of your meals (breakfast, lunch or dinner) with a justblitz smoothie each day and you will soon start to notice the benefits…
 
Nutrition
1 – Balanced & Customised
Unlike most bottled ‘shelf’ smoothies (typically 95% carbs and blended fruit), Justblitz recipes have the perfect balance of protein, carbs and good fats for your and your goals.
 
2 – Complete meal
Unlike most bottled smoothies you can have a Justblitz smoothie instead of breakfast, lunch or dinner.
 
3 – (Much) healthier per calorie
Bottled smoothies are pasteurised (heated to remove natural enzymes & bacteria) to extend their shelf life. This can remove up to 80% of certain delicate micronutrients. So we just give the ingredients to you to blend yourself. You get 100% full nutrient hit.
 
4 – Tastier

Well, that’s what we reckon. Though we might be biased.

3 main reasons.
 
First, our bodies absorb nutrients from natural foods much better than from artificial pills. This is called “bioavailability”. Your smoothie contains fruits, grains, seeds, veg, nuts and superfoods – all natural sources of vitamins, minerals and phytonutrients.
 
Second, while we have pills for headline nutrients & minerals we know about (e.g. vitamin B, C, calcium, iron etc.) natural superfoods provide hundreds (possibly thousands) more nutrients we need. Our bodies function much better (increased cognitive power, higher energy levels, better sleep, longer life expectancy, stronger immune system etc.).
 
Third, we use a spread of different ingredients, superfoods and seeds so you don’t get the same thing day in/day out. Variety is key to getting a good “micronutrient profile spread” (i.e. you benefits of all foods, not just some).
The natural vitamins, minerals and phytonutrients you get from a varied diet of seasonal (or frozen) foods (fruit, veg, nuts, superfoods etc.) are vastly more effective than pills. However the following 2 are rather useful.
 
  1. Vitamin DWhy? Because we get it from sunlight and we don’t get enough. How much? 1000-2000IU in summer and 2000-4000IU in winter (depending on your physical size).
  2. Fish oil – Specifically IFOS certified omega 3 fish oil (Google it). Why? Because our body needs it and we don’t get enough fish. And even if we did, fish now contain toxins due to humanity putting harmful chemicals in the oceans so we get less “net” (sorry) benefit from fish. Good fish oil supplements are filtered by centrifuge which removes the bad compounds. How much? Look for supplements that give you at least 2000mg actual (the amount of “EPA” and “DHA” combined) omega 3.

 

No. For 3 reasons.
 
Fat doesn’t make you fat
Low-fat was popular in the 80’s. But so was Footloose. Scientists have firmly established that eating too much food (not fat) makes you fat.
 
You miss out on the good stuff
Foods such as seeds, nuts and avocado contain fat soluble vitamins (A, D, E, K) which bolster your immune system, skin health and a load of other useful stuff. They also contain good fats (mono & polyunsaturated fats & omega 3) which boost your brain.
 
Fat can help burn fat
Fats in food (even saturated fats) help your body produce hormones that tell it to burn its own fat stores for energy.
Yes. Take our quiz and choose ‘Gain muscle’ as your goal. Your smoothie macro ratios (protein, carbs, fats) and size (calories) will be calibrated to your body for optimal muscle gain.
Yes. Take our quiz and choose ‘lose fat’ as your goal. Each week we’ll deliver a box of breakfast smoothie mix packs adjusted to your body and tuned for fat loss.
You clearly know your stuff. Not right now. You’ll be able to at some point. We’re working out how best to do it.

They are the main reason Justblitz smoothies help you feel and perform better.

While we know about (and can make in a lab) nutrients like vitamin A, vitamin B, calcium, magnesium etc., our bodies evolved regularly eating thousands of other natural molecules called “phytonutrients”. Most of these we don’t know about and can’t make in a lab. They are available in fresh or frozen natural foods (fruit, veg, nuts etc.).

We know our bodies use them in tiny amounts for for things like skin health, fighting disease and possibly thousands or millions of other functions.

These molecules are very delicate. As soon as you pick a strawberry, these phytonutrients start degrading. That’s why we use ingredients frozen at source – the phytonutrients are locked in till you blitz so you get maximal phytonutrient concentrations.

Bottled smoothies from supermarkets have to be pasteurised (heated) to give them sufficient shelf life. This removes phytonutrients so you get a fraction (possibly less than 1%) of the nutrients you’d have got if you’d blitzed the ingredients from frozen or within 2 hours of picking.

This is why replacing your daily breakfast with a Justblitz smoothie can help you feel & perform so much better. It gives you the stuff your body is evolved to function with but does not get from a Western diet.

Philosophy
Simple. Our singular, obsessive goal is to help you live a longer, happier, healthier life.
 
To achieve this we will firstly cram you full of natural nutrients in exactly the right amount for your physiology & goals. Every day.
 
Secondly have you really, really enjoy the experience by making it super tasty.
 
Thirdly make it as quick, convenient and as easy as possible.
 
Any ideas how we could improve, make it healthier, tastier or easier? Email me. charlie@justblitz.com.
There is no spoon.
Science
When you blend your smoothie the spinning blades trap and dissolve a small amount of air in the dense liquid. When you stop blending the air slowly starts to leave the liquid and the level goes down.
 
This is also the reason it feels “fluffier” if you drink it right away and if you leave it a while it feels heavier.
Delivery & Subscription

Right now, we can only deliver on Fridays.

Reason? We’re still a young company and are not yet geared up to implement multi-day delivery. We’re working on it! This is obviously super inconvenient for many people, probably you if you’re reading this.

When we finally start offering more delivery days we’ll ping an email round to our subscribers to let them know and announce it on our social media pages. So subscribe here to our newsletter and follow us on Facebook and Instagram!

We use special thermal packaging plus either dry ice or gel packs which will keep your packs frozen for up to 48 hours.
 
If life gets in the way and they have slightly thawed by the time you get to them, check them. If the packs still contain ice crystals and feel as cold as if refrigerated (4 degrees c) you can safely refreeze and use as normal. (If they re-freeze into blocks bash them to break up before you put into blender.)
 
If they are completely thawed you can refrigerate the packs for up to 48 hours (then discard) but do not re-freeze!
 
If they thawed because the courier delivered them late please tell us theteam@justblitz.com and we’ll make it right.
Store your recipe packs in the freezer. They taste best blended straight from frozen.

Packs, Recipes & Ingredients
So you get maximal “nutrient density” (micronutrients, minerals and phytonutrients per calorie) from your smoothie. Fruits and vegetables start losing nutrient richness from the moment they are picked or pulled out of the ground. Freezing them instantly “locks in” these goodies till you blend them up and drink them
 
(Plus it tastes nicer.)
Most are. We’re currently too small to be sure we can source organic versions of all the ingredients we need each week with 100% reliability. So we do what we can. One day we’ll make sure everything is 100% organic.
 
In the meantime, don’t worry. We’re nutritionists and we’re fine with it. There is a very slight benefit to organic ingredients but it is more marginal than most think. For most, upgrading to a Justblitz smoothie over their current breakfast will be so much of an upgrade that having it also all organic would be like finding yourself sat on a soft, fluffy cushion on your lifeboat off the Titanic.
Yes. We only source 100% gluten-free ingredients for all our recipes. This includes our oats, muesli and granola – all gluten-free versions.
…are listed on the individual smoothie pages. And with each box you get a smart Recipe Card for each smoothie with allergens.
Not yet. Our current smoothie workshop is too small to eliminate risk of trace amounts of nuts or other allergens. However we don’t like this. We feel strongly that nobody should miss out.  Therefore, as soon as we have a facility big enough, we will silo off an area where we can safely prep recipes specially adjusted for you. This is a priority. Bear with us.
You use the whole pack. It is designed to give you exactly the right amounts for your goals (fat loss, health boost, muscle gain etc.). But mainly because each pack contains ingredients that balance each other out e.g. fruit and veg. If you try and split it you might end up with (for example) a spinach and oat smoothie.
Because (in right amount) they add depth of flavour and add loads of micronutrient goodness without adding many calories.
Because it tastes foul in smoothies. OK not that bad. But we did hundreds (literally) of taste tests with kale. Its taste is much stronger than other veg so the amount you can add before taste overpowers is way under amount you need for it to be beneficial. So we use other veg. Tastes better, more nutrients.
(Yes, we know that other companies have lovely smoothies with kale in. Inside info: there isn’t much kale in there….)

Yes. Your recipes are high protein and some have slow release carbs meaning you feel fuller for longer.

Of course! Everyone has their favourite. Though do try and have variety once in a while so you get the benefits of having lots of different ingredient nutritional profiles.

Time for some Smoothie Science. Some recipes contain over 23 ingredients! There are 7 ingredient types we put in each to get the perfect smoothie.
 
Fruit
Because it’s delicious. And good for you.
 
Veg
We add just enough to add depth of flavour. Adds phytonutrients (good) without adding calories.
 
Good fats
Usually nuts (peanuts, cashews or hazelnuts work best) and/or avocado. Gives a delicious smooth texture. Contributes monounsaturated fats which are great for your hormones.
 
Grains
Such as homemade muesli, oats, rye flakes and brown rice flakes. Gives breakfasty ‘crunch’ and makes you feel fuller for longer. 
 
Protein
Our natural protein boosts taste, provides amino acids and makes you feel fuller. Win, win, win.
 
Milled seeds
Provide a satisfying ‘bite’ to smoothie texture. Milled (crushed) for better digestion. Source of brain-boosting omega 3!
 
Superfoods
We add as much as we can to each recipe before it starts tasting odd. Reason: we want to maximise the “nutrient density” (about of micronutrients, minerals and phytonutrients per calorie) of each smoothie so you derive maximal benefit from it.
Up to 3 months. Use-by date on pack.
Making your smoothies
Empty entire pack into blender (straight from freezer). Add water (or milk, almond milk – whatever you like). There’s a guideline amount of water to add on each pack however you could add less if you want it thicker, more if you want it thinner.
Yes! Justblitz tastes great with just water but we love it when our customers experiment. Jonnie (one of our packers) uses cranberry juice. Our Digital Marketing Guru Jess alternates between almond milk and runny low-fat yoghurt. Our founder Charlie adds two-thirds fridge-cold water, one-third semi-skimmed milk. But he’s odd.
 
Adding liquid with calories in it (i.e. anything other than water) will change the nutritional profile of your smoothie. But that’s fine as long as you take it into account!
 
Do you have a preference? Tell us on Facebook & Insta! #justblitz #smoothies @JustblitzSmoothies
Absolutely! If you discover a mind-blowing combination, tell us on Facebook & Insta! #justblitz #smoothies @JustblitzSmoothies
We love praise and hate criticism. But criticism helps us improve your recipes. Which makes you healthier & happier. So bring it. Email Charlie directly at charlie@justblitz.com. 
While most of them are pretty colours we’ll admit that some look a little, well, beige.
 
We could make them look prettier and more Insta-friendly by swapping out ingredients but that would make them less delicious and less good for you. So we won’t.
Your smoothie is made of raw, unhomogenised ingredients so a few minutes after blending it will start to split. This is completely normal and natural (and good for you). Just give it a 5 sec shake/blend/stir and you’re good to go.
Here are potential causes:
  1. Too little water – try adding more water (milk, almond milk or whatever you’re using) to help ‘grease the wheel’
  2. Too dense – if you’re using a thick liquid such as yoghurt try adding something more runny (less viscous) like water or skimmed milk.
  3. Cheap blender – there are lots of cheap blenders on the market that don’t have the grunt. Invest in a decent blender with at least 1000W (the more the better).
If you don’t drink immediately just put in fridge or thermos flask/bottle and it’ll be good for at least 6 hours. The layers will separate but that’s completely natural. Give it a good shake and you’re good to go.
 
Bottled smoothies last longer because they are pasteurised (removing many of the nutrients).
We’ve burned out lots of blenders in our quest for the Ultimate Smoothie!
 
For most people we recommend at least a 1000 watt NutriBullet or equivalent with a min 750ml cup.
 
The bigger and more active you are, the bigger your smoothie will be. Serious smoothie blitzers and those on larger (>400kcal) recipes should look at more substantial ones with over 1 litre cups (such as Vitamix S30).

1 – A freezer.
2 – A blender.

That’s it. Use a thermos flask if you want to take your smoothie with you and keep it ice cold.
