Amazing Grass Green Superfood Review: A Good Way to Increase Your Nutrient Intake


  • Products come in a variety of flavors
  • A convenient way to increase fruit and vegetable intake
  • Safe for most people
  • Well-priced, and you can subscribe and save


  • Contains a proprietary blend, so exact ingredient amounts are unknown
  • No third-party testing seal

Research has shown that eating a daily diet rich in fruits and vegetables may help reduce the risk of illnesses such as type 2 diabetes, some cancers, obesity, and heart disease. (1)

However, just one in ten adults meets the average recommended intake for fruits and vegetables. (1)

While nothing can replace a well-rounded diet, there may be an additional way to boost your intake.

Research has shown that supplementation of greens powders may provide some of the health benefits of eating fruits and vegetables and aid in decreasing inflammation. (2)

In this article, we will cover Amazing Grass Greens Blend powder, what the research says about its health benefits, the safety and side effects, and review comparable powders.

What Is Amazing Grass Green Superfood?

Amazing Grass, formerly called Green Superfood, provides a convenient way to increase your intake of nutrition.

It is a fruit, vegetable, and superfood powder mixture that can be added to water or juice, blended into a smoothie, or even baked into a recipe.

The product was born after founders Brandon and Todd discovered how incredible they felt from getting in their daily greens.

In 2002, both founders decided to leave their jobs to pursue their dream of building a greens supplement that would provide the benefits of daily greens conveniently.

The product is organically grown and thoughtfully harvested on a family farm in Kansas.

The grass used in the powder is slowly grown outdoors to support deep root growth, allowing for optimal absorption of nutrients and minerals.

The grass is harvested at its nutritional peak, and only the greenest tops are used.

Within 90–120 minutes of harvest, the Grass is dehydrated and pressed into pellets to ensure optimal availability of nutrients.

To further protect the availability of the nutrients, the pellets are kept frozen underground in a limestone cave.

Before creating the final products, the pellets are ground down in a fine powder, making the nutrition bio-available and easy to digest.

Amazing Grass Greens Blend comes in original, chocolate, and berry flavors and claims to:

  • Provide natural energy with greens and antioxidant superfoods.
  • Support digestion with added fiber.
  • Support immunity with vitamins C and K.

Furthermore, the product is available in additional formulations such as:

  • Energy
  • Immune System Health
  • Cleansing & Detox

Amazing Grass Greens Blend supplement provides a comprehensive blend of nutrients, minerals, probiotics, and fiber that may provide a convenient way to support your health goals.

Does Amazing Grass Greens Blend Work? We Evaluate the Claims

Amazing Grass Greens blend claims to increase natural energy, support digestive health, and enhance immunity when taken daily.

Below we’ll go over the available research behind the ingredients used in Amazing Grass’ greens blend to address the benefits.

Increases Natural Energy

Amazing Grass Greens Blend contains various vitamins, minerals, and herbs that may support energy levels.

Green Food Blend

The Greens product contains a proprietary blend of organic green foods such as wheatgrass, barley, alfalfa, spinach, spirulina, chlorella, and broccoli.

These greens, such as wheatgrass and barley, offer a rich source of vitamins and minerals and contain powerful antioxidant properties. (3, 4)

Antioxidants are substances that combat the destruction of cells by free radicals, unstable molecules that can cause damage, illness, and aging.

Research has found that wheatgrass’ content of minerals, phytochemicals, enzymes, and vitamins is easily absorbed. (5)

Additionally, clinical trials support the use of wheatgrass for combating stress and have found that it may be a therapeutic approach to preventing inflammation. (5, 6)

Chronic inflammation can be a debilitating symptom, often leading to chronic fatigue and poorly functioning cellular energy and immune function. (7)

Barley grass is an additional powerful green that may promote better sleep, regulate blood pressure, enhance immunity, fight fatigue, and promote antioxidant activity. (8)

Furthermore, the inclusion of chlorella, a green algae, is valuable for its vitamin B12, folate, and iron content. (9)

Deficiencies in each of these nutrients may lead to excess weakness and fatigue. (10, 11)

The blend of greens provides a rich source of nutrition that, when combined with a healthy diet, adequate sleep, and exercise, may encourage normal energy levels.

Antioxidant Blend

Amazing Grass Greens Blend contains an impressive antioxidant blend that may support energy by including organic green tea leaf extract and maca.

Green tea extract contains less caffeine than coffee but may still provide a boost in energy.

Green tea also contains the amino acid L-theanine. Research has found it may improve cognition and reduce stress and anxiety-like symptoms. (12)

Additionally, the combination of L-theanine and caffeine work together to decrease tiredness and improve alertness. (13)

The blend also contains maca, an adaptogenic herb that is rich in fiber, essential amino acids, fatty acids, and vitamin C. (14)

An adaptogen is an herb known for supporting the body’s response to stress.

While more research is needed, limited studies have linked maca to enhanced reproductive health, decreased fatigue, improved digestive health, and antioxidant effects. (15)

The combination of antioxidants, specifically green tea extract and maca, alongside a balanced diet and lifestyle may support normal energy levels and improve alertness.


Amazing Grass Greens Blend contains an impressive blend of green grasses and antioxidants. While the proprietary blend makes it difficult to know how much of each ingredient is included, the components are supported by clinical research. When combined with a healthy diet and lifestyle, Amazing Grass may help normal energy levels.

Supports Digestion

Amazing Grass Greens Blend contains a fiber blend and a digestive enzyme and probiotic blend that may support digestive health.

Fiber Blend

Dietary fiber is an essential part of digestive health.

A diet high in fiber may regulate bowel movements and encourage a healthy bowel. (16)

Amazing Grass contains a blend of organic flaxseed and apple pectin, which are excellent fiber sources.

Flaxseed has been found to reduce the symptoms of constipation, irritable bowel syndrome, and episodes of diarrhea. (17)

Additionally, research supports the intake of pectin for improving gut bacteria and decreasing the risk of colon cancer and gut imbalance. (18)

Apple pectin serves as an essential prebiotic to support the effect of probiotics in the gut. (18)

Prebiotics, such as fiber, fuel probiotics which helps healthy gut bacteria grow.

The recommended fiber intake is at least 21 to 25 grams a day for women, and 30 to 38 grams a day for men. (19)

Amazing Grass provides 3 grams of fiber in a single serving.

While this fiber content is not enough to replace a diet rich in fruits, vegetables, and whole grains, it may be a start.

When combined with a balanced diet, Amazing Grass Greens Blend may improve your digestion.

Digestive Enzyme and Probiotic Blend

Digestive enzymes assist in breaking down proteins, carbohydrates, and fats, and their supplementation may play a role in the management of digestive disorders. (20)

Research supports digestive enzymes as adjunctive therapy to support digestive function. (20)

Additionally, probiotics such as Lactobacillus acidophilus are safe and effective in treating digestive disorders. (21)

Amazing Grass Greens Blend contains a proprietary blend of enzymes and probiotics such as Lactobacillus acidophilus.

A proprietary blend means only the ingredients are listed but without their exact amount.

Without knowing the specific CFU content of L. acidophilus, it isn’t easy to understand how much benefit it may provide.

CFU stands for ”colony forming units” and refers to the number of live probiotic cells in each serving.

Learn More About Probiotics: Probiotics 101


Amazing Grass Greens Blend’s fiber, enzyme, and probiotic content is backed by research to support digestive health. However, it is unclear how much of each ingredient is available to provide benefits due to the proprietary blend.

Supports Immunity

Amazing Grass Greens Blend contains multiple vitamins and minerals that support immune health, particularly vitamins A, C, and K.

Vitamin K

Vitamin K plays a crucial role in stimulating immune and inflammatory responses in the body.

Vitamin K can also slow or inhibit dangerous cell growth, and low vitamin K levels are associated with certain types of cancer and disease conditions. (22)

The recommended daily amount of vitamin K for adult women 19 years and older is 120 mcg. For men 19 years and older, the recommended amount is 90 mcg. (23)

Leafy greens such as collards, turnips, spinach, kale, and broccoli are excellent sources of vitamin K.

While vitamin K deficiency is rare, individuals with conditions such as celiac disease, cystic fibrosis, or who have undergone weight loss surgery may have difficulty absorbing vitamin K. (24)

Amazing Grass contains 70 mcg of vitamin K.

Vitamin C

Amazing Grass also contains Vitamin C, a powerful antioxidant.

Vitamin C plays a crucial role in immune defense by supporting various immune system functions. (25)

The Recommended Dietary Allowance for adults 19 years and older is 90 mg for men and 75 mg for women each day. (26)

Sources of vitamin C include:

  • Citrus
  • Bell peppers
  • Strawberries
  • Tomatoes
  • Broccoli, cabbage, and Brussels sprouts
  • White potatoes

While vitamin C deficiency is rare, it may occur with a diet low in fruits and vegetables or in those who smoke or abuse alcohol and drugs. (26)

Amazing Grass Greens Blend contains 16 mg of Vitamin C alongside a blend of antioxidant-rich foods.

While this alone cannot take the place of a varied diet, it may help you reach your daily goals when combined with a diet rich in fruits and vegetables.

Vitamin A

Finally, vitamin A is an anti-inflammatory vitamin due to its critical role in enhancing immune function. (27)

Vitamin A is available in foods such as spinach, carrots, cantaloupe, dairy products, and liver. (28)

The recommended daily amount of vitamin A is 900 mcg for adult men and 700 mcg for adult women. (28)

Amazing Grass contains 60 mcg of vitamin A.

Most vitamin A should come from your diet. However, supplementation may benefit individuals with a poor intake of vitamin A-rich foods or those with a condition that increases the need for Vitamin A, such as eye disease or pancreatic disease. (28)


Amazing Grass Greens Blend contains various vitamins and minerals, such as vitamins A, C, and K, that, when combined with a healthy diet and lifestyle, may support immune health.

Amazing Grass’ Product Line

Amazing Grass contains additional formulations with the same ingredients as the original Greens Blend, plus added boosts, such as energy, immune health, and cleansing.

Greens Blend Energy

Amazing Grass Energy contains 80 mg of plant-based caffeine from yerba mate and matcha green tea.

The U.S. Food and Drug Administration considers up to 400 mg of caffeine a safe amount for healthy adults to consume daily. However, those who are more sensitive to caffeine may need to limit or avoid it.

The energy blend contains the same ingredients as the original, with the added caffeine boost.

Both yerba mate and green tea may increase focus, alertness, and energy and decrease fatigue. (29)

The energy blend comes in watermelon and lemon-lime flavors.

If you are looking for a pick-me-up alongside a serving of fruits and vegetables, Amazing Grass Greens Blend Energy may be a great choice.

Immune System Health

Amazing Grass offers three varieties of immune system health blends, including an antioxidant blend and two immunity blends, tangerine and elderberry.

Greens Blend Antioxidant

The antioxidant blend contains a higher dose of antioxidants and includes elderberry.

Elderberry has been found to decrease the severity and length of respiratory illness, with no associated risk. (30)

Greens Blend Immunity

The immunity blends contain a proprietary mushroom blend, including cordyceps, reishi, shiitake, and turkey tail.

Mushrooms of this variety have been regarded as containing potent immune-enhancing properties. They may even provide benefits in adjunctive therapy for cancer patients. (31)

There is no daily recommended dose of mushrooms, but some reports have seen benefits with 1–3 grams of dosing. (32)

The immunity blends contain 1 gram of the proprietary mushroom blend.

Both immunity blends contain a higher dose of Vitamin C, and the tangerine flavor has vitamin D.

Vitamin D has been shown to have anti-inflammatory effects and may decrease the incidence of illness. (33)

The sun is the best source of vitamin D. However, additional food sources include:

  • Cod liver oil
  • Salmon
  • Swordfish
  • Tuna fish
  • Orange juice fortified with vitamin D
  • Dairy and plant milk fortified with vitamin D

The Recommended Dietary Allowance for people 19 years and older is 600 IU daily. For adults older than 70 years, it is 800 IU daily. However, the Endocrine Society recommends 1,500 to 2,000 IU daily. (34)

The tangerine immunity blend offers 12.5 mcg (500 IUs) of Vitamin D.

If you are looking to support your immune system, Amazing Grass Greens Blend Antioxidant or Greens Blend Immunity may be helpful when added to a balanced diet and healthy lifestyle.

Cleansing & Detox

The Cleansing & Detox line contains added ingredients such as peppermint, fennel, ginger, and lemon peel.

These ingredients have a significant body of data to support their digestive-enhancing properties. (35, 36)

Additionally, ginger has been found to support gastrointestinal disorders and contains anti-inflammatory, anti-nausea, and antioxidant properties. (37)

When combined with a balanced diet and healthy lifestyle, the Amazing Grass Greens Blend Cleansing & Detox line of products may provide additional digestive support.

Side Effects, Safety, and Dosage

Each of the ingredients in Amazing Grass Greens Blends are generally safe for healthy individuals and is supported by research on their intended use.

If you are taking prescription medications, such as blood pressure-lowering, heart medication, or blood thinners, it is always best to check with your physician before supplementation,

Additionally, while this product is generally safe for pregnant and nursing mothers, it is always important to confirm with your doctor.

For optimal benefits, the recommended serving is one scoop a day. The blends can be added to water, juice, a smoothie, or mixed into yogurt or baked goods.

Amazing Grass website offers a variety of creative recipes to try.

Each of the products is gluten-free, dairy-free, organic, vegetarian, and has no added sugar. Only one product is not vegan, the Immunity Tangerine blend, due to the added vitamin D, which comes from sheep’s wool.

If you are not accustomed to concentrated fruit and vegetable drinks, you may experience slight stomach upset or increased bowel movement.

Cost and Where to Buy

Amazing Grass is available for a one-time purchase of $32.99 or a monthly subscription of $26.39 directly on its website.

Refunds are available for all unused and unopened products returned within 30 days of purchase.

Additionally, Amazing Grass is sold on Amazon, Target, GNC, Rite Aid, and Walmart. The best value is on Amazon, however.

You get 100 servings for $65.59 bringing the total cost to 65 cents per serving vs $1.09 per serving if bought directly from the brand’s website (or 87 cents per serving through their subscription).

How Amazing Grass Greens Blend Compares to Alternatives

Compared to a whole-food multivitamin, such as MegaFood, Amazing Grass Greens Blend is not as comprehensive.

It does not contain vitamins and minerals such as B complex, vitamin D, copper, selenium, and iodine. If you are looking for a more comprehensive supplement, a multivitamin may be better.

However, several greens powder blends are available, including Athletic Greens, Garden of Life, and Vibrant Health Green Vibrance.

Athletic Greens

Athletic Greens (AG1) is a greens powder that provides all of the vitamins and minerals of a typical multivitamin.

AG1 is vegetarian, vegan, gluten-free, and organic.

Like Amazing Grass Greens Blend, AG1 contains vitamins, minerals, antioxidants, digestive enzymes, and probiotics.

However, AG1 is more comprehensive, covers the bases of a traditional multivitamin, and contains a third-party testing seal.

Third-party testing helps to ensure the quality and accuracy of the product.

AG1 is more expensive than Amazing Grass Greens Blend.

One-Time Purchase:

  • $99.00 for a 30-day pouch
  • $109.00 for a 30-day supply of travel packets

Monthly Subscription:

  • $79.00 for a 30-day pouch, which includes a storage jar and shaker bottle
  • $89.00 for a 30-day supply of the travel packets

AG1 has a 60-day money-back guarantee that allows you to initiate a complete refund if you are not satisfied with the product within 60 days of your purchase.


If you are looking for a comprehensive greens powder to take the place of a multivitamin, then AG1 may be the better choice. However, if you eat a balanced diet and want to increase your intake of grasses and antioxidants for a lower price, Amazing Grass would be the best choice.

Try Athletic Greens

Garden of Life

Garden of Life’s Raw Organic Perfect Food Green Superfood Powder is highly comparable to the Amazing Grass Green blend.

The product is certified organic, non-GMO, vegan, and certified gluten-free by NSF.

NSF is a third-party testing label to confirm testing completed by an outside, non-bias company.

The two most notable differences in the formulations are the addition of sprouts in Garden of Life’s products, such as amaranth, quinoa, buckwheat, lentils, and vitamins (riboflavin and folate).

Additionally, Garden of Life’s Green Superfood Powder contains 70% of the daily value of vitamin K.

This is an essential consideration for someone on blood-thinning medication, such as Warfarin. Too much vitamin K may affect your medication’s ability to work.

The green powder is priced at $36.79 for 30 servings.


While the price and the ingredients are comparable, an important consideration should be the higher vitamin K content of Garden of Life’s product if you are on prescription medications.

Try Garden Of Life

Vibrant Health Green Vibrance

Green Vibrance contains an extensive list of vitamins, minerals, greens, grasses, herbs, enzymes, and probiotics.

The product is Non-GMO, plant-based, gluten-free, and vegan.

Compared to Amazing Grass, the product is more comprehensive and includes vitamins B12, D, and folate.

It also contains a wider variety of probiotic strains, with 25 billion CFUs.

The cost of Green Vibrance is $54.00 for a 30-day supply, or a monthly membership cost of $45.01.


Green Vibrance is more comprehensive than Amazing Grass but comes at a higher price. If you are looking for a blend that contains a greater variety of probiotics, Green Vibrance may be the best choice. However, if you are looking for a convenient way to increase your greens intake, Amazing Grass is a great lower-cost option.

Frequently Asked Questions

How do I store opened containers?

Amazing Grass recommends storing opened containers in either the fridge or freezer to best preserve the nutrients. A cool cabinet will work too.

Can I take the Greens Blend while pregnant or nursing?

In most cases, a wheatgrass supplement — such as the Greens Blend — is considered safe while pregnant or breastfeeding.

However, it is always recommended to consult your doctor before beginning any supplementation.

Are the containers BPA-free?

Yes, all the containers and the lids are BPA-free.

Is it okay to take more than one serving per day? What is the recommended limit?

All of the products are safe to consume more than one serving per day. However, if you eat a balanced diet of fruit and vegetables, you should not need more than one serving per day.

The Bottom Line: Should You Try Amazing Grass?

Amazing Grass Green Superfood provides a convenient way of increasing your greens intake.

The combination of green grasses, digestive enzymes, probiotic blend, and fiber and antioxidant blends may support normal energy levels, digestive health, and immune health.

As a dietitian, I recommend always prioritizing eating a diet high in whole, plant foods before turning to a supplement for the best nutrition.

However, many adults are not eating enough fruits and vegetables required for optimal health. In this case, supplementing with a product like Amazing Grass Green Superfood may be helpful.

When combined with a healthy diet, this green powder offers an easy boost to your nutrition intake.
