AG1 is the most polished option in the greens-powder category: a broad formula, NSF Certified for Sport testing and a generous 90-day first-order guarantee. It is also one of the priciest, so it makes most sense if it genuinely replaces several other supplements in your cupboard.
What we like
- NSF Certified for Sport, with screening for more than 280 banned substances
- Broad formula of 75-plus vitamins, minerals, greens, adaptogens, prebiotics and probiotics
- Only about 40 calories and under 1 g of sugar per scoop
- 90-day money-back guarantee on the first order
- Travel packs and gummies make it easy to stay consistent away from home
Keep in mind
- Costs more per serving than most basic greens powders
- Blend-style labeling means you cannot judge every individual ingredient dose
- The earthy, lightly sweet flavor takes some people a week or two to like
- Not a substitute for vegetables, fruit and a varied diet
AG1, the brand that started life as Athletic Greens, is the product most people picture when they hear the words "greens powder." The idea is simple: one level scoop stirred into cold water each morning, covering a long list of vitamins, minerals, plant extracts, prebiotic fiber and probiotics that might otherwise come from several separate bottles.
In our research we focused on what is actually in the scoop, how the newer Next Gen and Pro versions differ, what the testing claims mean, and whether the subscription pricing stacks up against cheaper greens blends. The short version: AG1 is well made and unusually well tested, but you are paying a premium for convenience and polish.
What AG1 is (and what it is not)
AG1 is a daily foundational nutrition drink, not a meal replacement and not a protein shake. A standard serving weighs about 13 g and delivers roughly 40 calories, 2 g of protein, 2 g of fiber and less than 1 g of naturally occurring sugar. It is designed to sit alongside your normal meals rather than replace them.
The formula draws on more than 75 ingredients grouped into vitamins and minerals (including vitamin C, vitamin E, zinc and B vitamins), a superfood and greens complex, adaptogens such as ashwagandha, digestive enzymes, and a gut-focused section with prebiotics and 10 billion CFU of probiotics. It is free from GMOs, gluten, dairy, egg, peanuts and artificial sweeteners, and the brand describes it as suitable for vegan, paleo and keto eating patterns.
What it is not: a cure-all. It will not make up for a diet that is consistently low in whole foods, and the energy and gut benefits people report are subjective and vary a lot from person to person.
The current AG1 lineup
The range has grown beyond the original powder, which can make the store a little confusing on a first visit. Here is how it breaks down in 2026:
- AG1 Next Gen is the current core powder, sold as a monthly subscription at about $79, or roughly $2.63 per serving.
- AG1 Pro is a larger 20 g serving aimed at people who want a more concentrated daily formula, listed at about $99 per month on subscription.
- AG1 Essentials Gummies come 30 servings to a container (eight gummies per serving), at $49 per month on subscription or $64 as a one-time purchase.
- Travel packs hold the same powder in single-serve sachets for trips and gym bags.
- Add-ons include a Vitamin D3 + K2 liquid, AG Omega3 capsules and AGZ, a melatonin-free evening drink.
New subscribers typically receive a welcome kit with a shaker and storage canister, which is useful if you plan to keep the pouch on the counter.

Testing and quality: why it stands out
The single strongest argument for AG1 is its testing. The brand holds NSF Certified for Sport status, which involves independent screening for contaminants and for more than 280 substances banned in competitive sport. That matters for athletes who are drug-tested, but it is also a useful signal for everyday buyers in a category where label accuracy can be patchy.
The trade-off is transparency at the ingredient level. Like most greens powders, AG1 groups many plant ingredients into blends, so you can see the total weight of each blend but not always the exact amount of every component. If you want to know precisely how much ashwagandha or each probiotic strain you are getting, a single-ingredient approach gives you more control.
How to decide which version to buy first
For most first-time buyers, the core Next Gen powder on a monthly subscription is the sensible starting point. It is the version most reviews and comparisons refer to, and the first order is covered by the 90-day guarantee, which gives you a full three months to decide whether it earns its place.
- Choose travel packs if you are rarely home in the morning or want to keep a few at the office.
- Choose the gummies if you simply will not drink a greens powder, accepting that a gummy format carries a different, narrower nutrient profile.
- Consider AG1 Pro only if you already like the original and want a higher-dose daily formula.
Mix one level scoop into 8 to 10 oz of cold water and shake well. The flavor is mild, earthy and lightly sweet, with a hint of pineapple and vanilla. Many people find it easier to drink very cold or blended into a smoothie.
Price, subscription and guarantee
AG1 is a premium product and priced like one. At roughly $79 a month for the core powder, it costs noticeably more than many grocery-store greens blends. Whether that is good value depends on what it replaces: if it lets you drop a multivitamin, a probiotic and a separate greens product, the maths can look reasonable; if you take it on top of all of those, it becomes an expensive habit.
Subscriptions can be adjusted, and new US subscribers get free shipping. The 90-day no-risk guarantee on the first order is one of the more generous in the category and is handled by contacting customer support for a refund.
Who should buy AG1, and who should look elsewhere
AG1 suits busy adults, frequent travelers and people with irregular eating patterns who value a single, consistent routine and are happy to pay for strong third-party testing. It is also a good fit for athletes who need NSF Certified for Sport products.
It is less suited to budget-focused shoppers, people who prefer to see every dose on the label, and anyone on medication or managing a health condition who has not checked the ingredient list with a clinician first. If you mainly want the greens, a simpler powder such as Live it Up, or a gummy option like Grüns, may cover what you need for less.
Our verdict: a well-tested, convenient daily formula with a strong guarantee. Worth trying if the price fits your budget, but think of it as a nutritional safety net rather than a shortcut to health.
