I'm a sucker for a simple wellness routine. I don’t have a crazy supplement stack, and in general, the fewer, more intuitive steps in my morning routine, the better.
Which is why AG1—the OG greens-based all-in-one powder that combines vitamins, minerals, probiotics, prebiotics, adaptogens, and superfoods—has always been appealing to me. Instead of mixing up multiple powders or downing a handful of pills, it delivers the nutritional supportyou need to supplement what a diet might be missing in one daily scoop.
I’ve known about AG1—formerly known as Athletic Greens—for years. I first heard about it through wellness podcasters like Rich Roll, and more recently I’ve noticed it has picked up a steady roster of celebrity fans, including Hugh Jackman. The product originally launched in 2010, and years later, people are still talking about it. Long-term customers report supported energy and mood. So I was curious to see what had kept so many people loyal to the product for so long.
And I knew that AG1 introduced its updated AG1 Next Gen formula in May 2025, so I decided it was finally time to see what all the buzz was about. After several weeks of testing it as part of my morning routine, here's what I found.

- Boost of energy throughout my morning
- Feeling nourished with less cravings
- Vitamins, adaptogens, probiotics, and digestive enzymes in one scoop

- Have to use a bottle brush to clean if you don’t have a dishwasher
What Is in AG1?
AG1 is a Daily Health Drink designed to consolidate a wide range of nutrients into a single scoop. The formula includes a lot of ingredients (75+ to be exact), but they fit into a few buckets which makes it easier to understand:
First are the core vitamins and minerals that function like a foundational multivitamin, including B complex vitamins, biotin, folate, magnesium, vitamins A, B12, E, and K2, along with zinc citrate. Next are adaptogens, such as ashwagandha, which helps the body manage stress, and rhodiola, which supports mood, brain, and nervous system health.
The formula also includes antioxidants and a mix of superfoods and functional mushrooms, like beet root and shiitake mushrooms, which provide a variety of phytonutrients that are known to support physical health.
But supplements can be notoriously hard on the gut, so AG1 also has digestive enzymes that help break down nutrients, food and ease bloating or discomfort, and pre- and probiotics that work to support gut health and regularity.
The Next Gen formula has a few improvements on the original one: They’ve upgraded the probiotics strains to include five that are well-backed by science and added more vitamins and minerals, like molybdenum which supports cellular metabolism and choline, which supports nervous system function. They also listened to feedback about how some of the ingredient quantities were too low to be functional, so they increased the size of the 30-day supply and scoop size so that each serving is 13 grams instead of 12, resulting in more nutrients. On top of that, AG1’s first flavors: Citrus, Berry and Original.
The Science That Backs It Up
A 2025 randomized, triple-blind study of 120 healthy adults found that AG1 Next Gen improved key nutrient biomarkers among healthy participants whose fruit and vegetable intake reflected that of the average US adult. It’s worth noting that the study included researchers affiliated with the brand, though it was still conducted by a third-party, and a randomized controlled clinical trial with a robust methodology.
One thing I especially appreciate is that AG1 is NSF Certified for Sport. I’ve had many conversations with health and supplement experts over the years as a journalist, and this certification often comes up as one of the more rigorous third-party standards in the supplement space, particularly for athletes who compete in professional sports. But for the everyday user, it adds an extra layer of reassurance around quality and testing that many other brands don’t always prioritize, especially in the supplements category where oversight can vary widely. Basically, the certification guarantees that they are screened for hundreds of contaminants or prohibited substances, and that what is on the label matches what’s in the powder.
My Testing Experience:
Most mornings, I fill a glass with cold water, pour in a scoop of the bright green powder, and stir or shake until it dissolves.
Taste-wise, it’s pretty good. There is a slightly earthy, vegetal flavor to it (as you would expect with a greens powder) but with a top layer of sweet pineapple and vanilla. As you mix it with water, the grittiness of the greens never fully disappears, but I’ve tested other greens powders and they have the same problem. I found out mid-way through testing that the texture improves when you mix it with a frother rather than just stirring it, so that became my go-to method, but it wasn’t necessary.
I’ve also seen plenty of people blend AG1 into morning smoothies, where the flavor is likely easier to mask. If I had a blender, I would probably go that route, but for now, I’ve just been keeping it simple with water. I tested the classic flavor which would be easiest to blend into other beverages, but next time I might go for the Citrus or Berry which may taste better if you’re drinking it on its own.
I got the original set which comes with a subscription and includes a 30-day supply, storage container and scoop, and AG1 shaker. I love that it comes in the large pouch that I can keep at home and feel like I’m doing my part to cut down on packaging waste, but if you find yourself on the go each morning, it also comes in portable packs, which I used when I was traveling.
Over the course of testing, the most noticeable shift for me was the sense of consistency it brought to my mornings. Starting the day with AG1 became a simple habit that helped create more structure in my routine, even on busy days when my schedule felt unpredictable.
I also found myself being more intentional about my overall wellness habits. Having a consistent morning ritual made it easier to stay mindful throughout the day and make choices that aligned with how I wanted to feel. As someone who has never been great at sticking to a morning routine, that consistency ended up being one of the most valuable parts of the experience.
My Verdict
I don't think AG1 replaces fruits and vegetables, and the brand is clear that whole foods should remain the foundation of a healthy diet. Instead, it appeals to people like me, who have an imperfect wellness routine and could use more nutritional support.
On busy weeks, travel days, or mornings when I’m neglecting my nutrition (which happens more often than I’d like to admit), it feels like an easy way to help fill in some gaps and maintain my energy while feeling like I’m doing something good for my body. And while I wouldn’t say it’s an essential, it has earned a place in my lineup because it’s simple, easy to stick with, and made me feel a little bit healthier.
