As a Registered Dietitian, I’ve seen a decrease in the consumption of fruits and vegetables. In fact, according to the CDC, it seems that only 10% of adults manage to reach the daily intake of fresh produce. (Source)

While I always encourage people to focus on increasing their consumption of fresh ingredients, I know it’s sometimes challenging to reach it. It might be because you don’t have high-quality products available, or you are a picky eater who is not keen on eating vegetables.

No matter the reason, green powder supplements can be a handy tool to help you get more nutrients into your diet. But what is the best-recommended greens supplement?

KOS Greens and Supergreen Tonik are two popular green powder supplements. If you are still unsure which one you should pick, we’ve created the task of making the ultimate comparison. Here, we’ll go over the differences in health benefits, ingredients, taste, and pricing.

What Is Supergreen Tonik?

Supergreen Tonik is a carefully formulated green powder supplement created by Adam Wright. After years of battling with Chronic Fatigue Syndrome, he decided to get extra help from natural sources. As a result, he created Supergreen Tonik.

The formula contains 38 high-quality ingredients to help improve overall wellness, boost energy levels, and enhance immune function. Here, you’ll find different green powders, herbs, spices, adaptogens, and nootropics.

One of the biggest benefits of Supergreen Tonik is its fully transparent label. Most green powder supplements use proprietary blends, meaning you cannot determine how much of each ingredient they use.

However, that is not the case with Supergreen Tonik. While we are going to talk more about this later in the article, Supergreen Tonik details how much of each ingredient they use.


  • Made with 38 high-quality ingredients
  • Has a fully transparent label
  • Third-party tested
  • Made in the US
  • Has two flavors available: mint and berry
  • Offers a 365-day money-back guarantee


  • Only one size is available

What Is KOS Greens?

KOS Greens Tub

KOS Greens is a green powder supplement made with 13 ingredients. Most of the ingredients in the formula are green powders, with a couple of fruits and prebiotic fiber.

The company KOS is named after the Greek island where Hippocrates was born (the father of medicine). Their main goal is to help provide essential nutrients to people since most people seem to have at least one nutrient deficiency.

While their green powder supplement is one of their most popular supplements, they also offer other supplements, such as plant-based proteins and energy gummies.

One of the biggest drawbacks of KOS Greens is that it is made with proprietary blends. This means you cannot determine how much of each ingredient they use.

The problem is that no matter if they have the best ingredients if they don’t come in clinically proven doses, they might not provide the intended benefits.


  • Made in an NSF-certified facility
  • Made with non-GMO ingredients
  • Made in the US
  • Made with all organic ingredients
  • Offers a 60-day money-back guarantee


  • Only one flavor is available (green apple sorbet)
  • Made with proprietary blends
  • Might contain underdosed ingredients

KOS Greens vs Supergreen Tonik: Benefits

Green powder supplements provide several health benefits. Generally speaking, they can improve overall wellness. But there is more to green powder supplements.

Since each formula has different ingredients, they both provide different health benefits. Here, we’ll take a closer look at the health benefits provided by each supplement.

Supergreen Tonik

Supergreen Tonik might provide the following health benefits:

  • Reduced inflammation
  • Boost energy levels
  • Enhanced immune function
  • Brain health support
  • Improved digestion

KOS Greens

KOS Greens might provide the following health benefits:

  • Decreased inflammation
  • Support immune function
  • Improves digestion
  • Support gut health

KOS Greens vs Supergreen Tonik: Ingredients

KOS Greens and Supergreen Tonik use different ingredients. Supergreen Tonik uses almost three times as many ingredients as KOS Greens.

Another big difference is that while KOS Greens focuses on green powders, there is not a great variety in its ingredients. On the other hand,  Supergreen Tonik has different green powders, herbs, spices, adaptogens, and nootropics.

Finally, Supergreen Tonik has a fully transparent label, while KOS Greens uses proprietary blends.

One scoop of Supergreen Tonik (11.3 grams) offers 35 calories, 6 grams of carbs, 2 grams of fiber, and 3 grams of proteins. The 38 ingredients are divided into three main blends:

In addition, one scoop also offers a good dose of vitamin A (14%), vitamin C (111%), vitamin D (100%), vitamin E (65%), vitamin K (42%), thiamin (167%), riboflavin (154%), niacin (125%), folate (83%), vitamin B12 (417%), vitamin B6 (118%), biotin (1,000%), pantothenic acid (200%), calcium (11%), zinc (136%), selenium (91%), iron (61%), copper (222%), magnesium (87%), sodium (3%), and potassium (3%).

As you can see, Supergreen Tonik provides a good dose of essential vitamins and minerals. It also contains powerful antioxidants that can help reduce inflammation and support immune function.

There are other key ingredients in the Supergreen Tonik formula, such as Ashwagandha and Rhodiola extract, which are powerful adaptogens. This means they can help reduce stress and support a good night’s sleep. (Source)

In addition, it also has ingredients that provide antibacterial and antimicrobial properties to help improve immune function.

One of the biggest benefits of Supergreen Tonik is that is has a fully transparent label. This makes it easier to determine if the ingredients come in clinically proven doses (which they are).

According to research, the recommended intake for spirulina is 1,000 to 8,000 mg. Supergreen Tonik provides 2,000 mg, which is within the recommended intake. (Source)

KOS Greens

KOS Greens Label

One scoop of KOS Greens offers 30 calories, 6 grams of carbs, 2 grams of fiber, and 1 gram of protein. Its 13 ingredients are divided into four blends.

  • Organic algae superfood blend (250 mg): organic chlorella and organic spirulina
  • Organic alkalizing greens blend (4 g): organic wheatgrass juice powder, organic wheatgrass whole powder, and organic oat grass whole powder. 
  • Organic fruit and veggie blend (3.25 g): organic lemon juice powder, organic cabbage powder, organic kale powder, organic broccoli, organic apple, and organic green bell pepper.
  • Organic digestive prebiotic blend (2 g): organic isomalto-oligosacharide and organic acacia gum.

Most of the ingredients of KOS Greens are powerful antioxidants, which, as mentioned, can decrease inflammation and decrease the risk of chronic illnesses.

In addition, the digestive prebiotic blend contains two powerful prebiotics, which can help improve gut health. As a result, it can help improve digestion and boost immune function.

However, one of the biggest drawbacks of KOS Greens is that it uses proprietary blends. And, it seems that certain ingredients might be underdosed.

We previously saw that the recommended intake for spirulina is 1,000 to 8,000 mg. Nonetheless, in KOS Greens, you find spirulina in the algae superfood blend, which weighs 250 mg (and it contains chlorella and spirulina). So, it seems that some ingredients can be underdosed.

KOS Greens vs Supergreen Tonik: Taste

Most people are not fond of green powder supplements. Since they contain several green powders, it might result in an “earthy” drink. However, companies work hard to mask the flavors to provide a delicious experience. 

The best way to determine if you might like the supplement is to check customer reviews. So, let’s check what people are saying about each supplement.

Supergreen Tonik

Supergreen Tonik provides two flavors to choose from: mint and berry. The mint flavor has a refreshing taste, while the berry flavor is sweeter.

Both options are widely accepted by customers and they seem to enjoy taking it each day.

“A Great Pick me Up”

Having tried various other greens supplements, I have to say this is by far the best I’ve had!! The taste is easily the best by a long way tbh… much more palatable than the others… actually pleasant!! The impact is more noticeable over a period of time…2 to 4 weeks, then you really start to notice it… reduction in brain fog, faster thought process and overall more positive well-being!

KOS Greens

KOS Greens only has one flavor available, which is green apple sorbet. While most people seem to enjoy the flavor, keep in mind that if you don’t like it you would need to add other ingredients to mask the flavor since there are no other option available.

“My husband is not a vegetable eater, so I get him the greens powder supplement. He loves it. Highly recommended. Tastes like green Jolly Rancher!”


“Really good taste and easy to get down. It does taste well, green, but not overbearing and subtly sweet. I find it is a little hard to dissolve or fully mix sometimes, but once it’s fully mixed it’s tasty! My kids always take it from me. The ingredients are great and I feel like it has helped my digestive health noticeably after just a few uses. I definitely see the benefit to taking this regularly!”


KOS Greens vs Supergreen Tonik: Cost

Green powder supplements are somewhat expensive. The cost depends on the ingredients, dosage, and any other benefit the company offers (such as money-back and certifications).

If you suffer from a chronic illness and take medication, make sure you consult with your doctor before adding any supplement. Some herbs, spices, and ingredients in green powder supplements might interact with certain medications.

If you want to pick the best option, the clear winner is Supergreen Tonik.
