GoKawiilThanks to a 1994 US Food and Drug Administration ruling that supplements are food, not medicine, green powders remain unregulated; they may or may not do what they claim, and may not contain the ingredients their labels specify. In fact, they may even contain unlabeled ingredients. Despite this lack of transparency, the health supplement market is booming. To help pin down the best, most trustworthy green powders that do what they claim and also taste good, I've spoken with dietitians and tried options from popular brands.
While greens powders aren’t harmful, they’re also expensive and not a silver bullet for pristine health. The dietitians with whom I spoke agreed that green powders won’t replace a healthy, varied diet. You need to eat your greens, plain and simple. But if you’re someone who doesn’t eat enough fruits and veggies, you and your health care provider may determine that certain greens powders may help bridge the nutritional gap.
Your doctor can help you determine which nutrients you're lacking and assess whether a specific greens powder may help to supplement. After trying many greens powders (with my doctor's approval!), I have noticed better, smoother digestion; heightened energy levels; and a general sense of wellness.
Is there a greens brand you want WIRED to try? Do you have one you swear by? Let me know in the comments below.
Updated June 2026: I’ve added new greens powders from AG1, Daily Elements, and Nuzest. I’ve also removed some older picks and checked for accuracy throughout.
