And, you don’t want to waste your money on any green powder supplement. After all, you find both high-quality supplements and junk.

One is marketed as the best green powder supplement for women, and the other is the all-in-one supplement that is so sure of its formula that it offers a 365-day money-back guarantee. At the end of the article, you’ll decide which one best suits your goals and needs.

What Is FS Greens?

FS Greens

FS Greens is a 21-ingredient green powder supplement that is uniquely formulated for women. The green powder supplement was created by a nutritionist and made in the UK by Free Soul.

It is also vegan, gluten-free, lactose-free, soy-free, and made with non-GMO ingredients. In addition, it doesn’t have any preservatives, artificial colors, flavors, or sweeteners.

Thanks to its ingredients, FS Green may provide the following health benefits:

  • Improved digestion
  • Increased energy levels
  • Enhanced immune function
  • Reduced stress
  • Better skin, hair, and nails

However, while there are several health benefits that FS Green may provide, there is one big con. It is made with proprietary blends.

Proprietary blends are when the company doesn’t state how much of each ingredient they use. As a result, it can be challenging to determine if the ingredients used come in clinically proven doses. The problem is that even if it provides the best ingredients if they are not clinically dosed, they may not have the intended benefits.

What Is Supergreen Tonik?

Supergreen Tonik is a green powder supplement made with 38 ingredients and created by the Human Tonik company. The man behind the company, Adam Wright, decided to create the supplement after battling chronic fatigue syndrome for several years.

The formula is vegan-friendly, made in the US, and made with all-natural ingredients. In addition, the supplement is third-party tested, meaning it is tested to guarantee its safety and purity.

The company is so proud of its product that it offers a 365-day money-back guarantee. If you don’t like the product, you can return it, meaning you can try the supplement risk-free.

The blend of ingredients in Supergreen Tonik may provide the following health benefits: 

  • Boosted energy levels
  • Improved gut health
  • Better digestion
  • Reduced inflammation
  • Improved cognitive function
  • Reduced stress levels

One of the features that make this green powder supplement stand out over FS Greens (and most green powder supplements) is its transparent label. This means you can determine how much of each ingredient is in the formula. As a result, you can determine if the ingredients come in clinically proven doses.

Nutritional Comparison

To help you select the best option between FS Greens and Supergreen Tonik, it’s important to compare their nutritional profile. Here is the nutritional information for each green powder supplement.

Supergreen Tonik not only has more ingredients than FS Greens (38 ingredients vs 21 ingredients), but it also contains twice the serving size. So, not only you get more product per serving, but also more ingredients.

Another big difference between them is their formulation. With Supergreen Tonik, you know which ingredients you are getting and at what doses. However, when it comes to FS Greens, you know which ingredients you are getting but not at what doses.

While both options contain high quality ingredients, all of the ingredients in Supergreen Tonik come from organic sources. With FS Greens, some are organic, but not all of them. So, if quality of the ingredients matter, Supergreen Tonik may be the best choice for you.

With that said, FS Greens contains some key ingredients that are worth standing out. For example, lucuma is a key antioxidant that can help reduce inflammation by reducing free radicals in the body. (Source)

Another ingredients in FS Greens is fennel seed extract, which can also help reduce inflammation but it is a powerful antimicrobial. As a result, it can help enhance immune function. (Source)

The rest of the ingredients in the FS Greens formula are other powerful antioxidants and mostly prebiotics, which can help restore gut health and provide digestive properties.

Supergreen Tonik contains three powerful blends. The all-organic green blend contains powerful antioxidants that can help reduce inflammation and decrease the risk of chronic illnesses. (Source)

The nootropics formula contains powerful ingredients, such as ashwagandha, which can help reduce stress and promote a good night’s sleep. (Source)

Other ingredients, like ginkgo, can help improve brain function by improving memory and focus. (Source)

Taste And Mixability

One of the big challenges that green powder supplements present is their taste. Due to the combination of green powders, most supplements have an “earthy” taste. So, taste can play an important role in choosing the right green powder supplements.

After all, you don’t want to purchase a supplement that you are not going to drink (or that you drink unwillingly) due to its taste.

FS Greens

FS Greens offers two flavors: mango and original. The original flavor doesn’t contain any sweeteners or flavors, which is ideal for those who prefer to mix their green powder supplements with other ingredients. But if you need to mask the taste, it’s better to opt for the mango flavor.

Browsing through the reviews section, I see that most customers enjoy FS Greens. They state that it has a good mixability and a nice mango taste.

Supergreen Tonik

Supergreen Tonik also offers two flavors to choose from: berry and mint. The berry option is ideal for those who prefer a sweet beverage, while the mint flavored offers a refreshing beverage. Both options can also be mixed with other ingredients to help boost its flavor.

Just like FS Greens, Supergreen Tonik has very positive reviews. People think that it also has good mixability, and both flavors are widely accepted.

Price And Value

There is a big price difference between FS Greens and Supergreen Tonik. While Supergreen Tonik is slightly more expensive than FS Greens, keep in mind that you are getting more features, such as a larger serving size, more ingredients, a money-back guarantee, third-party testing, and more organic ingredients.

FS Greens

There is only one pricing option available for FS Greens. One bag of this green powder supplement costs £30 (approximately $40). This means you pay $1.33 per serving.

But, you can save money if you enter their subscription savings. This gives you a 20% discount, bringing down the price to £24 per bag ($30). This reduces the price per serving to $1.00.

The company offers free shipping to orders above £36, meaning you would have to purchase at least two bags (or another product) to qualify for this discount.

Supergreen Tonik

Supergreen Tonik has three pricing options, which depend on how many tubs you purchase. In other words, buying in bulk significantly reduces the price.

Here is the pricing list for Supergreen Tonik:

  • One-month supply: $87 per tub ($2.85 per serving)
  • Three-month supply: $75.67 per tub ($2.52 per serving)
  • Six-month supply: $62.83 per tub ($2.09 per serving)

If you buy in bulk, the company offers you the option to purchase only one flavor or get both options (mint and berry).

In addition, the company also offers other bundles along with its other supplements, such as Red Tonik, Magne Tonik, and Synbio Tonik

Customer Reviews And Testimonials

The best way to know if a supplement works and what it tastes like (without trying it) is to check what other customers are saying. Both options have good reviews from their customers. Let’s take a closer look at what they are saying.

FS Greens

Most of the FS Green reviews from the website are positive. It contains over 300 reviews, most of which are five-star reviews. However, I like the transparency of the company since it also shows one-star or two-star reviews.

Generally speaking, most people agree that it is a supplement that has helped them reduce bloating, improve digestion, improve their energy, and it has a good taste.

When it comes to negative reviews, the majority of them are related to taste (remember that taste is subjective), and they didn’t experience any changes.

Check out a couple of reviews left by some customers:

“I follow a strict keto diet and use Supergreen Tonik to support my nutritional intake, absolutely love the berry taste.”


“It tastes so refreshing and good! I tried it with cold water it really brings out the crisp flavor so much more. I literally look forward to it every day and have to talk myself out of drinking it too early, SGT for the win!”


Supergreen Tonik

Supergreen Tonik also contains several positive reviews from customers. Most of them agree that it has helped them increase their energy, support their health, and improve their performance and recovery.

Here are some of the reviews left by some customers:

“In love! Getting this many vegetables in my diet hasn’t been possible before – but this is such an easy way to do it. I use a spoon as an ingredient in my morning smoothie, and it’s delish!”


“Obsessed with this! Been taking it for a month now, I can already see a difference, especially with bloating. The mango greens taste unreal! I would definitely recommend trying them.”

Final Words

FS Greens is a good green powder supplement for women who are on a low budget. It contains high-quality ingredients, and it seems to help improve digestion, boost energy, and enhance immune function.

However, if you are looking for FS Greens alternatives, Supergreen Tonik comes as a superior option due to its transparent formula, larger serving size, and more ingredients per serving. The formula comes in two delicious flavors to choose from: mint and berry.

So, if you are ready to take your green powder supplement game to the next level, Supergreen Tonik is one of the top-notch supplements available on the market. It comes at a cost-effective price, and the company offers a 365-day money-back guarantee so you can try the supplement risk-free.
