Getting your recommended daily allowance of fruits and vegetables can be challenging, but greens powders — like the KOS Show Me the Greens powder — can effectively add more greens, fruits, and vegetables to your intake. Greens powders are made up of dehydrated plant foods that are ground into powder, allowing you to cram a few extra servings of fruits and veggies into a single glass of water. And while many greens powders use fruit and vegetable blends, KOS stands out for its commitment to using only organic whole ingredients in these blends that make up its Show Me The Greens powder. 

It also includes a prebiotic blend of ingredients that may help keep your gut microbiome healthy and aid digestion, and the all-natural Green Apple Smoothie flavoring is designed to make it taste more like a smoothie from your local juice joint than yard waste. While the ingredients list doesn’t note the specific amounts of each ingredient (thanks to the proprietary blends) or the amounts of vitamins per serving, these perks combined with the affordable cost make KOS Show Me The Greens powder worth a closer look.

Main Takeaways

  • KOS Show Me The Greens powder is ideal for people who are looking for organic, whole-food ingredients, as everything in this powder is derived from organic fruits and vegetables. 
  • An added prebiotic blend of isomalto-oligosaccharide and acacia gum may aid in gut health and digestion by providing nutrients to your existing gut microbiome (versus probiotics, which contain the actual intestinal bacteria that make up your gut microbiome).
  • The price is right with this greens powder. While some higher-end greens powders can cost about $3 to $4 per serving, KOS Show Me The Greens powder runs about $1.10 per scoop.

This greens powder features a wide variety of vitamins, minerals, and prebiotics sourced from all-natural and organic superfoods. It's got everything you need to help promote gut health and proper nutrition without any added sugars or artificial flavors all packed in a refreshing Green Apple Smoothie flavor.

KOS Show Me The Greens Powder Highlights

KOS’s greens powder is a combination of proprietary blends extracted from whole fruits and vegetables. The main components are a 3.25-gram fruit and veggie blend with powders made from organic lemon juice, kale, cabbage, broccoli, red pepper, and apples. The greens blend is a four-gram mix of wheatgrass juice powder, wheatgrass whole powder, and oat grass powder, all of which are organic as well. A 250mg mix of chlorella and spirulina algae adds a bit of protein, and KOS’s two-gram prebiotic blend of acacia gum and isomalto-oligosaccharide can help promote gut health by providing food for the microflora in your digestive system

The Green Apple Sorbet flavor is intended to brighten up the taste without added sugars, thanks to the monk fruit and stevia extracts, and at about $1.10 a serving, KOS’s greens powder is on the lower end of the price range for greens powders. While the nutritional label discloses calories, macronutrients, and some mineral content, there is no information on the vitamin amounts. So if you’re someone who likes to track their nutrients meticulously, this may not be the right option for you.

Who Should Buy KOS Show Me The Greens Powder

  • Athletes who are looking for more than just vegetables, since this powder also includes a prebiotic blend that may help aid gut health.
  • People who prefer organic, whole food ingredients, as the ingredients in this blend all come from organic fruits and vegetables. 
  • Anyone who doesn’t want to empty their bank account for a greens powder. At around $29 for a 28-serving tub, KOS Show Me The Greens powder is one of the more affordable greens powders on the market.

Who Shouldn’t Buy KOS Show Me The Greens Powder

  • Anyone who wants to stack supplements. The green apple flavor will be hard to blend with, say, chocolate protein powder
  • People who would prefer a complete list of nutritional info as KOS doesn’t list the vitamin amounts on its packaging.
  • Anyone looking to avoid allergens, since KOS Show Me The Greens is produced in a facility that may also process peanuts, nuts, wheat, and other allergens.

Price and Buying Options

KOS Show Me The Greens powder only comes in one flavor in a 28-serving container. It can be found on Amazon for about $31.04, which breaks down to about $1.10 per serving, making it much more affordable than many greens powders on the market that can cost up to $3 or $4 per serving. Despite its lack of flavor variety, it gets extra credit for achieving its Green Apple Smoothie flavor with monk fruit and stevia instead of sugar or artificial sweeteners. If green apple isn’t your jam though, you may want to go another route. But at this price point for a fully organic greens powder, you may just learn to love it. 

KOS Show Me The Greens Powder Overall

The greens powder from KOS stands out for several reasons, the first of which is its completely organic ingredients list, which can be a plus for athletes who want to stay as natural as possible. Also, the addition of prebiotics gives the powder an edge with its potential to aid gut health, and the Green Apple flavor could be a plus for people who don’t like the taste of plain greens powders. And since its price point is on the lower side, this could be a solid option for those who want to save money without sacrificing quality. 


The proprietary blend of 13 ingredients (including spirulina, broccoli, kale, wheatgrass, and a prebiotic blend) is designed to help people add more servings of fruits and vegetables to their diets. The proprietary prebiotic blend includes isomalto-oligosaccharide powder and acacia gum that might help promote gut health. (1) Each serving has 30 calories, one gram of protein, zero grams of fat, and six grams of carbohydrates — only one of which is sugar. But more on these ingredients below.

KOS Organic Algae Superfood Blend

The Organic Algae Superfood Blend is a 250mg mix of organic chlorella (which studies have suggested may improve cholesterol and blood pressure levels), and organic spirulina (which can be an anti-inflammatory agent and immunity booster). (2)(3)

KOS Organic Alkalizing Greens Blend

This 4g blend of organic wheatgrass juice powder, organic wheatgrass powder, and organic oat grass powder, which are all rich in antioxidants and other nutrients, like vitamins A, C, E, and K. (4

KOS Organic Fruit and Veggie Blend

The Organic Fruit and Veggie Blend has a 3.25g combination of organic lemon juice powder, organic cabbage powder, organic kale powder, organic broccoli, organic apple, and organic green bell pepper, all of which contain antioxidants and are excellent sources of vitamins as well as minerals, like iron and potassium. (5)

KOS Organic Digestive Prebiotic Blend

The 2g blend is a mix of organic isomalto-oligosaccharide and organic acacia gum, both of which can provide nutrients for the microfauna in your gut microbiome, potentially improving gut health and digestion. (6)


The Green Apple Smoothie flavoring consists of organic apple and mint flavors, organic monk fruit extract, and organic stevia extract. The latter two are both all-natural, low-glycemic sweeteners. 

What To Consider Before Buying KOS Show Me The Greens Powder

There are a few considerations to make before going all in on this product. KOS Show Me The Greens powder is on the less expensive side of the greens powder spectrum, but its use of proprietary blends makes it impossible to know exactly how much of each ingredient you’re getting per scoop. Also, Green Apple Smoothie is the only flavor, which limits your options if you want to mix it with other powders. Users do get all organic ingredients, which may carry some health benefits over non-organic food. (7) But more on all of this below.

Proprietary Blends

KOS Show Me the Greens powder’s ingredients come in the form of proprietary blends. The downside to this is that companies aren’t required to list specific ingredient amounts of proprietary blends, so you can’t be sure of exactly how much of each ingredient is in each serving. If you’re wanting a greens powder with a specific amount of wheatgrass, prebiotics, or chlorella, this product may not be for you. But if you’re just trying to cram as many greens as you can into one glass, KOS has you covered here.


Each container of KOS Show Me The Greens powder has 28 single-scoop servings and will run you about $30, which makes it just over a dollar per serving. With other greens powders costing in the $3 to $4 range, that makes KOS Green Powder a wallet-friendly option, especially when you consider the organic ingredients and prebiotic stack that’s included. You can find cheaper greens powders, but many options under the $1 per serving range will lack features like prebiotics and flavors. Conversely, you can spend more (much more) on greens powders if you’re looking for more features like adaptogens, superfoods, or a full pro- and prebiotic stack.


The Green Apple Smoothie flavoring gets points for using zero added sugar and all-natural sweeteners. However, this is the only flavor this product comes in, so if you’re not into Green Apple Smoothie, you’re out of luck here. Also, there’s no unflavored option, so if you want to mix it with any other powders or supplements, you’ll have to do some alchemy to make the flavors work. 

Final Word

While it won’t completely replace your need for fruits and vegetables, KOS Show Me The Greens powder could be a good way to add more plant nutrients to your diet. In addition, the prebiotic blend of isomalto-oligosaccharide and acacia gum may help with digestion and gut health. Some studies on greens powders have also shown cardiovascular benefits like lower systolic and diastolic blood pressure. (8

Since KOS’s ingredients come in the form of proprietary blends, the specific amounts of each ingredient aren’t listed, which may be a downside for some who are looking for their exact nutrient intake. But the all-organic ingredients, price, and added prebiotics make KOS Show Me The Greens powder worth considering. 


What does KOS Show Me The Greens Powder do?

Since it’s made from dried fruits and vegetables, KOS Show Me the Greens is intended to be an easy way to make sure you’re getting enough fruits and vegetables in your diet, as well as an easy way to supplement a healthy diet with additional vitamins. KOS Show Me The Greens also adds a prebiotic stack that contains food for your gut biome, which may aid in gut health and digestion. 

How much does KOS Show Me The Greens cost?

A 28-serving container of KOS Show Me The Greens powder will cost about $29, which works out to about $1.10 per serving. This is actually on the lower end of the greens powder price spectrum. You can find less expensive greens powders, but these powders may lack the ingredients and perks that you’d find with Show Me The Greens.

Can I drink KOS Show Me The Greens powder every day?

Yes, when taken daily, Show Me The Greens can add beneficial vitamins and nutrients to supplement a healthy diet. Plus, it may aid in gut health, thanks to the powder’s prebiotic stack.
