Is the best greens powder the one that packs the most certified organic vegetables into one daily dose? The one that promises glowing skin, a boost of energy, and a fortified immune system?
We’d argue that the best greens powder is the one that you are actually going to drink. (The dusty bottles of multivitamins and dietary supplements in the back of your “wellness drawer” would agree.) So while the packaging will tell you plenty, the real question—“Is this something I’m going to be willing to consume once a day?”—can only be answered by a good old-fashioned taste test.
While they can’t replace a healthy diet, the benefits of greens powders have undeniable appeal. Kale salads for life, but why wouldn’t you want to gas up your morning smoothie with all the vitamins and minerals and nutrients that leafy greens provide? It seems like you can’t swing a crystal without hitting a new green superfood supplement brand on the market, so whether you’re interested in elevating your overall health or you just want something that tastes good, there is likely an option for you—and we’re here to help you find it.
First, we subjected our coworkers to an exhaustive taste test of the most popular and vegan-friendly greens powders on the market. While several products use sweeteners to mellow out the grassy taste, we found our favorites didn’t shy away from earthy flavors or hide behind artificial flavoring. They tasted as advertised—like powdered greens and proud of it. And they avoided mysterious fillers in favor of veggies, adaptogens, and all those good phytonutrients.
After narrowing our top picks, we consulted two registered dietitians/nutritionists: New York–based Amy Shapiro (MS, RD, CDN,) and Los Angeles–based Mascha Davis (MPH, RDN). They sifted through the hype and assessed the real impact of the best greens powders on the market.
The Claim: Athletic Greens says its AG1 blend contains 75 vitamins, minerals, and food-derived nutrients per serving, all sourced from ingredients like alfalfa, artichoke, and spirulina. It also includes probiotics and a long list of adaptogens, like ashwagandha, licorice, and shiitake mushroom. According to the website, Athletic Greens promotes better gut health, supports immunity, boosts energy, and helps with recovery.
The Reality: “This product is powerful and nutritionally dense,” Shapiro says, agreeing with the brand’s marketing claims. She likes how easy it is to prepare (just add water), which makes it easier to commit to each day. “Basically, taking this supplement in the morning will set you up for a strong immune system, healthy digestion, and loads of energy as long as you take it consistently and in conjunction with a solid diet,” says Shapiro. Davis does caution that, with “the sheer number of different ingredients” in the AG1 blend, you might not be getting all of them at a level that’s “actually beneficial.” And the product doesn’t come cheap, at $99 for 30 servings.
The Taste: AG1 has a fairly balanced flavor profile; it’s a little bit sweet (thanks to stevia) and a little bit earthy and grassy (thanks to the heavy dose of greens). When dissolved in water, it was plenty flavorful, but reviewers appreciated that it wasn’t too intense to stir into juice or a smoothie. And while the stevia is noticeable, it’s nowhere near as sweet as some of the other options we tested, like Primal Harvest. Athletic Greens did lose minor marks for the texture, which was a little bit grainy.
The Claim: Amazing Grass makes its products using organic, non-GMO fruits and vegetables sourced from a national network of small farmers. Its original Green Superfood powder blends vegetables, fruits, and greens with digestive enzymes and probiotics like wheatgrass, barley, alfalfa, açaí, and spirulina to increase energy levels, promote detoxification, and boost the immune system.
The Reality: “I am a fan of this product. There are many different greens here, and I love that the probiotics are paired with fiber. When probiotics have a prebiotic to feed off of, they have a higher likelihood of surviving transport through your gut,” Shapiro tells us. She was very impressed by the high dose of vitamin K (one serving has a whopping 85% of the recommended daily dose), and lack of added sugars. This greens powder supplement also contains vitamin A and vitamin C. There’s no shortage of micronutrients here.
