AG1 Review 2026: A Nutritionist’s Take

Jordan Hill, MCD, RD, CSSD is a Registered Dietitian and Certified Specialist in Sports Dietetics. She works with athletes of all ages, those struggling with disordered eating, and the general population looking to improve overall health and wellness.

As a registered dietitian, my clients frequently ask me to suggest simple ways to improve their nutrient intake. For many people, a busy schedule can sometimes get in the way of maintaining a balanced diet rich in fruits and vegetables. Greens powders initially caught my attention for their potential to help fill gaps in a typical diet.

Previously called Athletic Greens, AG1 is among the best-known, as it was one of the first greens powders to achieve mainstream popularity. Many athletes and social media influencers have partnered with AG1 to promote the dietary supplement, which features powdered leafy greens, superfoods, probiotics, digestive enzymes, and a high concentration of micronutrients.

I wanted to find out whether this product delivers on its many health and nutrition claims, so I took a close look at AG1’s ingredients and potential benefits and tried it for myself. In this AG1 review, I’ll share everything I learned about the science behind AG1 Next Gen, the brand’s latest iteration of its viral greens powder, along with my own experience using it, to help you decide whether it lives up to the online hype.

A Rundown of AG1

If you’ve ever searched online for “greens powders,” you’ve probably come across Athletic Greens, a vegan dietary supplement introduced in 2010. The company rebranded the supplement as AG1 in 2021, and in May 2025, it launched AG1 Next Gen, the latest iteration of the formula. Celebrity sportspeople like Allyson Felix and Lewis Hamilton promote AG1 as part of an active, healthy lifestyle.

According to the manufacturer, AG1 has been updated dozens of times based on developments in nutrition science, with several doctors and researchers contributing to the formulation. Although there are now similar products on the market, AG1 appears to have a loyal following, despite being one of the most expensive green powders available.

No added sugar or artificial sweeteners
Significant amount of dairy-free probiotics (10 billion CFU)
Wide variety of vitamins and minerals
NSF Certified for Sport and tested for 280 banned substances
Available in three flavors

What I Disliked

Very expensive (even with a subscription, it’s $79 per month)
Certain vitamins are included in excessive amounts
Sweetened with stevia, which can leave an artificial aftertaste
Contains soy
May provide trace amounts of caffeine from matcha

Is AG1 Next Gen Worth It?

In my line of work, I try to avoid making sweeping generalizations about nutrition. Everyone is unique, with specific health and wellness goals. Yet we all need to get a certain amount of nutrients, and the unfortunate fact is that the vast majority of Americans don’t eat enough fruits and vegetables. A daily greens powder is a useful way to increase your intake of vital nutrients, though it's not a substitute for whole foods.

AG1 contains 83 high-quality ingredients plus 10 billion CFU of probiotics in a proprietary formula that’s heavily researched and tested. But even after researching the product extensively, I can’t understand why it’s so expensive—especially since many other greens powders are a fraction of the cost.

For my personal tastes, I also found the grassy taste of the Original flavor, stevia aftertaste, and chalky consistency difficult to tolerate unless I mixed it with a sweet fruit smoothie (though some users love the flavors).

As the manufacturer’s name suggests, AG1 Next Gen is probably best suited for athletes who closely monitor their nutrient intake and are accustomed to large doses of vitamins and minerals. As a nutritional supplement for high-performance athletes, AG1 excels with its strict quality control standards and rigorous testing regimen, ensuring that it is free from hundreds of substances banned by professional sports organizations.

AG1 Next Gen might also be a good choice for individuals with vitamin deficiencies, as long as they recognize the potential for interactions with medications and consult their doctor before adding a new supplement to their routine.

What’s Better than AG1?

While AG1 Next Gen has clear benefits for serious athletes, there are more affordable greens powders for the rest of us. AG1 alternatives like Live it Up Super Greens and Bloom Greens offer many of the same benefits at more than $1 less per serving than AG1. I recommend choosing an all-natural product with a streamlined ingredient list that provides a healthy dose of vitamins and minerals derived from greens, fruits, and vegetables—without the unnecessary extras.

While I’d feel comfortable recommending each of these products to my clients, Live it Up Super Greens checks all the boxes for me for a top-tier greens powder supplement.

Health Targets

AG1 makes numerous claims about the potential benefits of AG1 Next Gen, though the company is careful to state that everyone’s experience with the product will be unique. The main areas of health that AG1 targets are nutrient gaps, energy and focus, digestion, and immunity. For each of these areas, I compared the health claims made by AG1 with the ingredients list, supplement facts, and cited research studies.

Fills Nutrient Gaps

One of the main reasons to take a green powder is to fill gaps in one's intake of essential nutrients. AG1 claims to be an all-in-one dietary supplement thanks to ingredients like beetroot powder, carrot root powder, papaya fruit powder, alfalfa, wheatgrass, barley grass, spirulina, and shiitake mushrooms.

According to the Supplement Facts, AG1 Next Gen contains significant amounts of micronutrients, including vitamins A, C, E, B6, thiamin, riboflavin, niacin, biotin, and pantothenic acid. However, I noticed that certain key minerals are included in relatively small amounts. For example, a serving of AG1 Next Gen contains 10% or less of the daily recommended values for magnesium, phosphorus, and calcium.

In the Scientific Research section of their website, AG1 cites a published in vitro study involving a simulated model of the digestive tract to show that, as a powder, AG1 Next Gen is more digestible than a multivitamin tablet and offers better bioavailability of magnesium, zinc, calcium, and potassium.

While this study appears to validate the efficacy of AG1 compared to a multivitamin, I wondered why the study only discusses minerals (most of which are included in AG1 Next Gen in relatively small amounts) and doesn’t mention vitamins.

Sustains Energy and Focus

Though the specific quantities are not specified, AG1 contains nutrient-dense ingredients like spirulina, chlorella, burdock root, and fruit and vegetable powders that offer a wide range of antioxidants, B-complex vitamins, and minerals crucial to helping maintain the body’s energy levels. Research also suggests that the adaptogenic herbs and functional mushrooms in AG1 Next Gen could help promote calm and a balanced stress response.

To support the claim that AG1 helps users sustain focus and normal energy levels throughout the day, AG1 cites an observational study of 35 healthy adults between the ages of 25 and 48. After one month of regular use of AG1, 97% of the study participants felt they had more energy. nIt’s encouraging that Athletic Greens confirmed that the self-reported study was conducted with “third-party clinical research centers to mitigate bias.”

Helps Digestion

The many purported digestive benefits of AG1 are another reason this supplement has gained mainstream popularity. With 10 billion CFU of dairy-free probiotics, the digestive enzyme bromelain, and prebiotics in the form of organic apple powder and inulin, AG1 Next Gen contains numerous ingredients that could support a healthy gut. Many people take AG1 intending to ease bloating, irregularity, and digestive discomfort.

In the same self-reported study of 35 healthy adults referenced above, 80% of the participants noticed less gas and bloating after taking AG1 daily for a month. To further underline AG1’s digestion-supporting properties, AG1 cites a clinical trial of 30 healthy adults ages 21-49.

When compared to a placebo group, AG1 supplementation resulted in a “2.9x increase in healthy bacteria in the gut” (specifically Lactobacillus acidophilus and Bifidobacterium bifidum) among those who consumed AG1 daily for a month. Although I noticed that the study's lead authors work for Athletic Greens, this clinical trial was peer-reviewed and published in the Journal of the International Society of Sports Nutrition, supporting its credibility.

Supports Immunity

With so many vitamins and minerals in this blend, it would be reasonable to expect AG1 to support a healthy immune system. Athletic Greens cites antioxidant-rich ingredients like acerola cherries, cocoa bean extract, grape seed extract, and CoQ10 as helping to support the body’s natural defenses against oxidative stress. Bioflavonoids and other polyphenols round out the purported immune-supporting components of AG1.

Based on the Supplement Facts, it seems likely that the large amounts of vitamins C and E (556% DV and 133% DV, respectively) in AG1 Next Gen could be useful for general immune support, as long as these vitamins have been included in a bioavailable form that the body can easily use.

AG1's Formula

With around 83 ingredients, AG1 Next Gen is famous for having one of the longest ingredient lists of any green powder. The bulk of AG1 Next Gen (7.5 g per serving) comes from what AG1 describes as the Active Superfood and Prebiotic Complex.

This blend features ingredients like apple powder, alkaline pea protein isolate, organic spirulina, artichoke leaf extract, citrus bioflavonoids extract, ginger root powder, organic matcha leaf powder, Rhodiola root, and ashwagandha, which have been linked to aiding with antioxidant levels and supporting mental clarity, mood, and focus.

The Daily Phytonutrient Complex (1.5 g per serving) adds additional fruit and vegetable powders, including broccoli, papaya, beetroot, organic wheatgrass, organic alfalfa, organic barley, carrot, pineapple, and a variety of fruit and herbal extracts such as acerola, rosehip, bilberry, hawthorn berry, milk thistle, grape seed, and reishi and shiitake mushrooms.

AG1 Next Gen also contains a dairy-free probiotic blend (37 mg, 10 billion CFU), which includes various Lactobacillus and Bifidobacterium strains. This dosage is on the relatively higher end compared with standard daily probiotic supplements, which typically range from 1-10 billion CFU, suggesting it could have a noticeable impact on gut health.

Pricing

As previously mentioned, AG1 was one of the first greens powders on the market and remains one of the most expensive. In the years since AG1 was introduced, many more affordable greens supplements have been developed, leaving customers to wonder whether AG1 is worth the price.

Unless you want to pay even more by ordering on Amazon, the only place to buy AG1 (which comes in 30-serving pouches) is via the Athletic Greens website. You can make a one-time purchase for $99 (plus a $9 shipping fee), or set up a subscription for $79 per month.

Subscriptions come with free shipping and a 90-day money-back guarantee and can be paused or canceled at any time. Subscribers also receive a “Welcome Kit” containing a canister, shaker, and five travel packs. Athletic Greens ships to customers in the United States, Canada, the United Kingdom, and the European Union.

For frequent travelers or those who constantly feel rushed for time, AG1 is available in travel packs, each holding a single serving. The travel packs are priced at $109 for a one-time order of 30 packs or $89 for a monthly subscription.

If multiple people in your household use AG1 (or you take two servings daily), a double subscription offers better value, at $149 per month for two 30-serving pouches or $169 for 60 travel packs per month. Setting up a double subscription will also earn you a year’s supply of Vitamin D3+K2 drops.

Taste and Texture

AG1 Next Gen is available in three flavors: Original, Citrus, and Berry. For this review, I sampled the Original flavor, which has a more earthy, grassy taste. The Citrus and Berry varieties offer fruit-forward alternatives for those who prefer a sweeter, more approachable flavor, and I’m curious to try one of these in the future to see how they measure up.

According to AG1, the original has a “subtly sweet flavor” that comes from “the natural essence of pineapple core and vanilla bean.” I appreciated the absence of sugar and artificial sweeteners, though I was disappointed that AG1 Next Gen uses stevia, which can be cloyingly sweet and leave a bitter aftertaste.

Overall, AG1 didn’t taste quite as unpleasant as I had expected after reading the customer reviews. I can’t say that I particularly enjoyed the Original flavor, though perhaps this isn’t surprising considering how many greens and mushrooms it contains. I could just about detect the pineapple and vanilla notes, though I thought it mostly tasted grassy, with a slight stevia aftertaste.

Athletic Greens recommends mixing a scoop of AG1 with 8-10 ounces of cool water and drinking the beverage on an empty stomach. Some reviewers mentioned that they had mixed AG1 with almond or oat milk. I also tried this, though the results were even less palatable than simply gulping it down with water.

Because of the sandy texture some customers mentioned, I found that the best way to take AG1 without having to taste it is to blend the powder into a fruit smoothie, though this may be too time-consuming for people looking for an easy way to take their greens on busy mornings. I also achieved a smoother texture by using a handheld milk frother.

AG1 Reviews From Customers

Customer reviews of AG1 Next Gen convey a mixed picture, with feedback being fairly divided across taste and value.

On the positive side, many customers seem to enjoy AG1’s new flavor options, and one reviewer found the new formula's taste an improvement over the original.

Other reviewers were less convinced. One reviewer who liked the formula’s contents still found the "greens" taste hard to get past and noted the powder never fully dissolved, adding that the price only makes sense if you value having everything in one product. Another reviewer ran into packaging issues (including a bag missing its included scoop) on top of disliking the taste and questioning the value for the price.

Overall, the reviews suggest AG1 Next Gen delivers a comprehensive formula, but whether it's worth the price tag depends on how palatable the taste and texture are to you.

FAQs About AG1 Next Gen

In my role as a dietitian, I’m regularly quizzed by my clients about the effectiveness and side effects of green powders. Here are my answers to some of the most common questions I’ve been asked about AG1 Next Gen.

Is AG1 better than a multivitamin?

According to the brand, AG1 replaces the need to take a multivitamin as it has a high content of micronutrients like vitamins A, C, E, B5, B6, B12, thiamin, riboflavin, niacin, and biotin. AG1 Next Gen cites an in vitro study indicating that Next Gen is more digestible than a multivitamin tablet and offers better bioavailability of certain minerals.

Yet, even if AG1 is at least as effective as a typical multivitamin, no supplement can take the place of a diet rich in whole fruits and vegetables, which naturally contain fiber, flavonoids, and phytonutrients.

Is Athletic Greens FDA-approved?

AG1 is not approved by the U.S. Food and Drug Administration because it is a dietary supplement and not a medicine. The FDA "does not approve dietary supplements for safety and effectiveness or their labeling before they are sold to the public.” Thus, consumers should consider AG1 and other greens powders solely for their potential to support daily nutrition rather than treat any illness or health problem.

Why is AG1 so expensive?

Compared to most greens powders, AG1 is very expensive, at $2.64 per serving with a monthly subscription. Notably, there are other greens blends that offer nutrient-dense ingredients like spirulina, chlorella, alfalfa, barley grass, wheat grass, spinach, digestive enzymes, and probiotics, yet are priced at less than $1.50 per serving. And while AG1 Next Gen has a whopping 83 ingredients, many of these ingredients are likely to be extraneous for the average consumer.

Is AG1 Next Gen actually good for you?

AG1 is a vegan, non-GMO, gluten-free product compatible with many diets and lifestyles. The ingredients in this green powder are generally very nutritious, especially the leafy greens and organic grasses. A serving of AG1 Next Gen provides significant quantities of vitamins and minerals, so be certain to talk to your doctor or a nutritionist about the right quantities for you.

Is AG1 worth it?

As I mentioned above, the best diet plan for you should be personalized to your unique health concerns, schedule, and goals. AG1 is an excellent greens powder that may be a good fit for a number of individuals looking to fill large nutrient gaps or help with athletic performance and recovery. However, AG1 may not be worth it for everyone.

Because of its synthetic vitamins, stuffed ingredient list, and high cost (nearly $1 more per serving than other greens powders like Live it Up Super Greens or Bloom Greens), AG1 is not the supplement I’d recommend to most of my clients. Instead, I’d suggest a more approachable, all-natural greens powder that focuses on high-quality ingredients and a great taste at a manageable price.
