Greens powders have become a popular dietary supplement due to their convenience. For individuals with busy schedules, a greens powder is a quick, easy way to boost your intake of essential micronutrients, including antioxidants, vitamins, and minerals. 

Unfortunately, greens powders aren’t known for their great taste, so at GGR, we’re on a mission to find the best greens powders that taste decent, too. Could Steel Greens superfood blend of greens and reds be one of them? You’ll find out in our Steel Greens review!

Steel Greens premixed

Steel Greens is actually a “super greens and reds” formula, which means it contains additional ingredients, such as berry powders, that a lot of other greens powders don’t. In this Steel Greens review, I’ll cover the ingredients and their benefits and drawbacks.

Before You Buy

  • This product doesn’t have any third-party testing or verification, so we recommend that athletes who are subject to drug testing look for a different greens powder.
  • Steel Greens itself is free from major allergens including tree nuts, but is manufactured using equipment that also processes major allergens, so it is not certified allergen-free.

Is Steel Greens Powder Worth It?

SteelFit Steel Greens Powder costs about $1.33 per serving, which is on the lower side of the spectrum for greens supplements. Because of this, and its robust ingredients list, we think it’s at least worth a try. Here’s a look at who Steel Greens might be a fit for and who should pass.

Steel Greens Powder 1

Great for:

  • Those looking for a well-rounded micronutrient supplement
  • People who like flavors like berry, pineapple, ginger, watermelon, and mint
  • Individuals who want an organic fruit and veggie blend

Not recommended for:

  • People allergic to gluten, tree nuts, peanuts, soy, or dairy
  • Those who do not want added enzymes or probiotics in their greens supplement

Experience Using Steel Greens

GGR staff writer and product tester Lauren Strong tried out SteelFit Steel Greens, and she had mostly positive things to say about it. She tried the powder in a couple of different ways, including prepared in a shaker bottle and stirred with a spoon in a glass. Lauren tried Steel Greens on separate occasions to get a fuller picture of how the powder felt while drinking it, immediately after drinking it, and hours later.

Price Per Serving

Steel Greens costs $39.95 for 30 servings, so it comes to about $1.33 per serving. This is relatively inexpensive as far as greens powders go; some others we have tried reach mind-boggling prices of more than $3 per serving—more expensive than some of the best protein powders or best pre-workouts.

For what’s included in Steel Greens, we think the price is a steal…see what I did there?

Steel Greens Mixed 1


There are three main parts to the Steel Greens formula: an organic greens blend, an organic reds blend, and an enzyme complex. Two other important listed ingredients aren’t part of a blend: kiwifruit powder and LactoSpore, a probiotic bacteria. Let’s look at each item in more detail.

The greens blend contains nine fruits and veggie powders: spinach, parsley, kale, barley grass, chlorella, bell pepper, green apple, banana, sweet potato, and broccoli. It’s no secret that consuming more green leafy and cruciferous vegetables is good for your health. Intake of such foods increases the intake of phytonutrients that fight against cognitive decline1, cardiovascular disease2, and more. 

The reds blend features five fruit powders: raspberry, blueberry, strawberry, cherry, pomegranates, and cranberry. Those fruits were chosen, according to SteelFit, for their richness in phytonutrients, including vitamins, minerals, antioxidants, and polyphenols. 

Sure enough, research shows us that plant foods with deep colors, such as the aforementioned five, contain high quantities of phytonutrients that can help the body combat inflammation and physiological stress3. Namely, diets high in vitamin A, vitamin C, and vitamin E are correlated to lower risks of chronic disease and mortality4.

Steel Greens Mixed 2

The enzyme complex contains five digestive enzymes5 commonly included in greens powders: 

  • Amylase, which breaks down carbohydrates
  • Cellulase, which also breaks down carbohydrates 
  • Protease, which breaks down proteins
  • Lipase, which breaks down fats
  • Lactase, which breaks down sugars from milk (lactose)

Steel Greens also contains powder of kiwifruit. There’s a big emphasis on this ingredient, with SteelFit claiming that the flesh of the fruit is rich in various nutrients, including potassium, vitamin C, vitamin E, vitamin K, and folate. SteelFit also says that the proteolytic enzyme actinidin in kiwifruit can help with protein digestion5

According to a 2018 review of studies in the European Journal of Nutrition6, “Kiwifruit should be considered as part of a natural and effective dietary strategy to tackle some of the major health and wellness concerns around the world.”

Finally, the powder includes the probiotic strain Bacillus coagulans as LactoSpore.

Unfortunately, the greens and reds blends are proprietary blends, which means we can’t tell how much of each ingredient is in the powder. We only know that the greens blend is present in a total of 5 grams per serving, and the reds blend is present in 2.5 grams per serving.

Steel Greens Up Close

Taste and Solubility 

Product tester Lauren Strong was pleasantly surprised with the taste and solubility of SteelFit Steel Greens. She tried the Mixed Berry flavor and liked that it tasted natural but good and “didn’t try to mask the fact it’s a green powder.” She believes Mixed Berry is probably the best flavor for greens powders.

As for solubility, Lauren says it “mixes OK” and is better when shaken versus stirred. Either way you prepare it, the clumps eventually work themselves out, but it goes faster with a shaker bottle according to Lauren.

Side Effects

Lauren did not experience any side effects after taking Steel Greens. Due to certain ingredients, such as stevia, enzymes, and probiotics, some individuals may experience forms of gastrointestinal distress. 

Third-Party Testing 

To our knowledge, Steel Greens powder is not independently verified by a third-party laboratory. There’s no indication of third-party testing on the SteelFit page for this product. While this doesn’t always mean a company is producing shady products, we recommend looking for products with third-party testing first. This is especially true for athletes or anyone who is subject to being tested for banned substances in sport.

As you can see by the above chart, there are quite a few differences between Steel Greens and AG1. Namely, the key ingredient list in AG1 is much longer. In addition to whole-food-sourced greens blend, AG1 contains multiple probiotic bacteria strains and an impressively long list of adaptogenic ingredients. Adaptogens like ashwagandha have been studied for their effects on stress relief and cognitive function.  

Additionally, all AG1 ingredients are non-GMO, and I didn’t see anything indicating the same on the SteelFit website regarding Steel Greens. Personally, I think the outcry against GMOs is unwarranted based on current research, but it feels worth calling out for people who prefer to avoid consuming GMOs.

AG1 is one of the most expensive greens powders we have tested, ringing in at a whopping $3.30 per serving. That’s more than double the cost per serving of Steel Greens. Depending on your priorities, it might be worth it, but our team of product testers admittedly thinks AG1 is a bit overpriced.

Ordering Steel Greens

It seems that Steel Greens is only available directly from SteelFit. As I write this, I don’t see it available on Amazon or from other common supplement retailers, including GNC, The Vitamin Shoppe, iHerb, or Target. The only other place I see it online is at Walmart.com. 

On the SteelFit website, buying Steel Greens is as easy as clicking “Add to Cart.” Unfortunately, there doesn’t seem to be a subscribe-and-save option. 

Customer Reviews

On the SteelFit website, Steel Greens powder has an average rating of 4.9 out of 5 stars from almost 300 customer reviews. Customers rave about the taste and texture of the powder, as well as positive effects like increased energy, improved digestion, a stronger immune system, and more. 

One customer wrote, “I’ve been consuming this product for almost one month now, and I have seriously noticed a difference in energy and digestion. It has worked wonders for me!”

Another gushed, “I can feel a remarkable difference since adding one serving a day. I will most definitely be continuing this supplement. The flavor has enough berry in it for me to just mix in with a bottle of water. If you want a vegetable supplement/replacement that tastes like candy, this isn’t for you. But if you’ve taken similar supplements and are looking for something a little more palatable, and an ingredient list that is simple and straightforward, this one is definitely worth trying.”

While we know that eating more fruits and vegetables is great for your health, there’s a lack of research overall on the beneficial effects of greens powders. This doesn’t mean customers are lying, but it does mean the “evidence” is purely anecdotal. That’s just something to remember when shopping for supplements. 

Final Verdict of Our Steel Greens Review

Steel Greens is a well-rounded superfood supplement at a reasonable price. We think it’s worth a try for anyone interested in a greens powder and doesn’t want to break the bank.

Steel Greens FAQs

Do greens powders help with hydration? 

A superfood powder like a greens blend doesn’t innately improve hydration status, but drinking a green drink every day can help you consume more fluids, which, yes, would help with hydration. If you are looking for a rehydration solution or hydration support, check out our guides to the best sports drinks, best electrolyte powders, and best electrolyte drinks.

Do green drinks help with gut health? 

Greens powders may help with some elements of gut health if they contain ingredients like probiotics, prebiotics, and/or digestive enzymes. Adding a dietary supplement rich in micronutrients to your daily routine can help with a lot of elements of your wellness, but supplements shouldn’t take the place of a nutrient-dense diet and proper health management. 

If you experience recurring gut health issues, it’s best to see a healthcare professional. Keep in mind that some ingredients in greens powders, such as artificial sweeteners, may actually increase gastrointestinal distress in those who are sensitive. 

What ingredients should a green powder have?

According to registered dietitian Bob Iafelice, Ph.D., who helped us formulate our testing methodologies for greens supplements, a greens powder should contain at least two of the following ingredient categories: 

Whole-food greens, including at least one of the following: chlorella, spirulina, barley grass, wheat grass, spinach, kale, or alfalfa
Digestive health ingredients, like prebiotics, probiotics, and/or digestive enzymes
Fruit extracts
Adaptogens, including ashwagandha, rhodiola, holy basil, chaga, cordyceps, ginseng
