About The Brand

Rheal Superfoods U.K. owners Charlotte and Sean developed a passion for wellness after both received medical diagnoses that would change their lives forever. Sean was diagnosed with a type of cancer called Non-Hodgkin’s Lymphoma, and Charlotte with an auto-immune illness known as celiac disease, a condition that required her to drastically restrict her diet.  

They both began a journey to find natural ways to fight fatigue and feel better, discovering a group of superfoods that helped them both. 

So with their new knowledge, they began providing quality superfood products to help others live healthier and happier. Recognized by Forbes, Dragon’s Den, and Women’s Health for their superfood blends, one of their best-selling is Clean Greens. 

What Is Rheal Superfoods Clean Greens?

Rheal uses certified organic ingredients to create a convenient and nutrient-dense super-green powder to help energize and optimize your health. 

A serving of this powder is like eating eight plant-based nutrients at once but saves time and effort since you just mix it into your water and drink it. 

Even though Clean Greens comes in at a decent price point, you may want to know more about the product before investing. Let’s take a look at Rheal Superfoods reviews, plus Clean Green’s health benefits and ingredient list.

Does It Really Work?

Rheal’s Clean Greens combines nutrient-dense superfoods to create a potentially powerful powder formula that works on many levels to help provide energy, gut health, and optimal brain functioning. Whether it really works for you as an individual depends on a number of factors. 

Yes, this product contains incredible superfoods that can fuel your day, but unfortunately, the brand uses these in a proprietary blend, and it’s not possible to tell if the dosages of each ingredient are high enough to have any clinical influence; hence we have no clinical evidence if they meet the recommended dosage on each of these superfood ingredients to be therapeutic. 

What Is A Superfood? 

A superfood generally describes a high-quality food like a fruit or vegetable that is deeply rich in nutrients and antioxidants that can help someone to have a healthy body. 

For food to meet superfood requirements, it should provide essential vitamins and minerals that support your immune system, overall health, and help maintain a healthy weight. 

Sometimes these foods are high in healthy fats, proteins, or fiber, and some contain all three. They tend to always be low in cholesterol, have zero trans fats, and have no refined sugar. 

How Do Clean Greens Work? 

Regardless of their unique nutritional values, these special foods may have a super effect on your body. Using a supplement like this can help you increase your daily intake of the necessary nutrients you need to have a healthy energy level and immune system. 

Users of Clean Greens have consistently left reviews about having a good experience with the product. Customers like the packaging and report an increase in energy levels, as well as digestive and immune health.

There are only a few bad reviews, primarily those who disagreed with the grassy taste. The other complaints consist of those who had an upset stomach after, such as nausea or diarrhea.

Rheal Superfoods Clean Greens Ingredients

It’s easy in this busy world to get in a rush and have very little time to eat all the nutritious foods you’re supposed to in a day, so it may help to have Clean Greens eight powerful and nutrient-rich superfoods to help ensure you get what you need. 

This combination of superfoods provides a whole list of nutrients a body needs to function optimally, like vitamin C, calcium, and iron. Your brain, immune system, and energy levels may benefit from the rich amount of antioxidants, fiber, and proteins. 

As a pending B corporation, Rheal Superfoods show they care about the environment with recyclable cardboard packaging, and for every order they receive, they plant a tree! So far, Over 200,000 trees have been planted thanks to their charity partnership with Ecologi. 

Clean Greens currently costs £25 as a one-time purchase or £18.75 by subscription, and they offer free U.K. shipping on all orders. Subscriptions offer 15% off recurring orders. You can skip a shipment or cancel at any time. They have a 30-day return policy. 

Baobab Powder

This powder comes from the large super fruit grown on the unique-looking Baobab tree in warmer places around the globe, like Africa, Australia, and India. It might feel like a funny word to say, but the medicinal benefits of baobab powder are as serious as can be.

Baobab fruit contains more antioxidants and vitamin C[1] than any other fruit, essential for fighting cell damage. It is also very rich in fiber, calcium, and prebiotics, making it a great addition to organic and green drinks. 

On top of these qualities, it’s also one of the most alkaline fruits in the world, which helps with the body’s pH balance. No wonder the Baobab tree is also known as the tree of life.

Barley Grass Powder

Barley grass is grown and harvested from the barley plant, a common cereal crop. This happens before its gluten-containing grain has grown. Rheal’s third-party testing helps ensure no cross-contamination, so this remains a gluten-free superfood to include in Clean Greens.

This grassy goodness contains lots of fiber, protein, and iron to aid in digestion and energy production. It’s rich in antioxidants that can support an immune system, like vitamins A, C, and K. 

While you might not see this fresh on store shelves, you may often see barley grass in other superfood drinks and products, as it’s easy to digest and benefits your overall health. 

Chlorella Powder

This ingredient comes from freshwater! Chlorella is a blue-green algae packed with nutrients. First, it can promote healthy detoxification through the natural chelation of heavy metals[2] and other toxins. 

Secondly, this popular dietary supplement is rich in chlorophyll, which makes it a great ingredient to add to immune health and gut improvement beverages. This sea vegetable also provides protein, antioxidants, and omega-3 fatty acids. 

Moringa Powder

Moringa[3] is such a superfood that it is referred to as a magical tree and a gift of nature by the National Institute of Health. This tall, tropical plant may help improve many conditions with its nutrient-dense value like:

  • Inflammation 
  • Low energy
  • Headaches
  • Stomach ulcers
  • Allergies

Spirulina Powder

If you avoid artificial food dyes, you might’ve noticed spirulina as one of the all-natural food coloring options available on today’s market. This superfood is a vibrant blue-green that can do more than just add color to your day. 

Cousin to Chlorella, this is another freshwater favorite that can be found around the globe. Also found seaside, these algae contain properties[4] that may help fight off infection, low energy, and memory loss. 

Other Ingredients

Rheal Superfoods Clean Greens contains just three more ingredients to finish up this superfood powder:

  • Pineapple powder — This dried pineapple purée is rich in vitamins, minerals, and fiber. 
  • Wheatgrass powder — This contains glutathione, amino acids, and chlorophyll, making it a great addition to an energizing immunity blend.

If you need to avoid any of these ingredients for some reason, here’s a list of alternatives you can choose from.

Health Benefits Of Rheal Superfoods Clean Green

Since these are organic ingredients, you don’t have to worry about them being grown using pesticides, insecticides, or genetically-modified organisms that can harm your health. Here are a few other health benefits you may receive from Clean Greens. 


Several of the Rheal Superfoods ingredients can help to detox and energize you, especially if this is in addition to a healthy diet and an active lifestyle. This blend contains prebiotics and digestive enzymes necessary for nutrient absorption. It has some of the most vitamin C-rich foods available, which your body needs to absorb iron,[6] which, in turn, can promote energy production. Prebiotics nurture the good bacteria in the gut and aid in good digestion.

Clean Greens does not contain any stimulants or preservatives, making this a great natural alternative to caffeinated energy drinks. 

Immune System Health 

There are many reasons super greens are suitable for the immune system, including their ability to promote healthy digestion and their rich source of antioxidants. Research shows that supplementing with plant-based green powders[7] daily may reduce the risk of chronic diseases and oxidative damage.  

Brain Health

All of the vitamins and minerals packed into this blend can promote overall cognitive health in a similar manner to focus-enhancing drinks. For example, studies show[8] that vitamin C can quickly and significantly improve a person’s mood and that deficiency in this vitamin can cause psychological abnormalities. 

Potential Side Effects

Since the ingredients in Clean Greens are anything but dirty; most people should be able to consume this allergen-free superfood powder without side effects. 

There is always the chance that you may be intolerant or allergic to one or more of its ingredients, so as with starting any new product, you’ll want to pay attention to how your body feels and reacts to it. 

There are a few reviews of people claiming they had digestive discomfort, nausea, and vomiting on days they consumed Clean Greens, but there are no warnings on Rheal’s websites about common reactions.  


There are 30 of the 5g servings in each Clean Greens container. The website mentions some helpful ideas for incorporating a spoonful of this powder into your day:

  • Simply add it to your lemon water.
  • Stir it into your oatmeal or yogurt.
  • Blend with your shake or smoothie. 
  • Mix into salads.

You can also make this palatable by stirring it into your salad dressing, vegetable dips, or serving of spaghetti sauce. Continue reading below for what reviewers say about this product and how they consume it. 

Rheal Superfoods Review: What Do Real Users Say?

I seriously felt the difference when I stopped drinking it. Now I have restocked with 3!

Magdalena P.

I’m typically a skeptic of stuff like this. However, after having 5g mixed in a water drink just before my breakfast religiously every day, I can honestly say I have much more energy throughout the day. I’ve also not been ill this winter. Yet. Coincidence? Possibly. The taste is meh, not holding your nose disgusting, though, which is a plus. Somewhere around just about palatable. Sure I could find something sweeter to mix it with, but trying to be a little healthier. This skeptic has had his mind blown and will be buying more Rheal Clean Greens and continuing this new routine.

Gareth E.

I can’t have any other superfood but rheal superfood. I am very pleased with all the products, and I have tried them all, even the energy bars. I highly recommend it. Bought for family members already, and I have my stash, too, until January. A very pleased customer since 2021.


2 weeks in, and my energy levels are the best they have ever been! I cannot recommend the clean greens enough. I was feeling super sluggish and always getting that 3 pm crash but just two weeks into Clean Greens, my energy levels have definitely gotten better. No 3 pm crash anymore, and I am sleeping better without waking up like I’ve been hit in the face by a saucepan! Tastes delish with ice cubes, a splash of apple juice, and some fresh lemon squeezed in there!


I have suffered from IBS for a few years now, and I have never found anything that works as well as this!! This drink is MAGICAL and has helped my tummy and digestive system so much. THANK YOU!! It may sound strange, but I add it to diluted blackcurrant juice, and it tastes awesome!!


Final Thought: Are Rheal Superfoods Worth Buying?

If you’re looking to find immunity-boosting beverages, Rheal Superfoods is an online brand selling several helpful products, like their Shroom Coffee, Berry Beauty, and nutrient-dense oat energy bars. You can also buy bundle drinks to save a few dollars or save with their subscription service.

For a newer company, they seem to have made a good choice of ingredients with scientific backing that may help them go far in the nutrition industry. 

Many reviewers proclaim this product, Clean Greens, is a game-changer for their energy levels and digestion. These eight superfoods can provide vitamins and minerals essential for your brain health and immune system and may be a great product for someone who needs help filling in the nutritional gaps in their diet.
