What to look for

Ingredient amounts
Proprietary blends list ingredients without amounts. Products that disclose doses let you see what you're actually getting.
Probiotics and fiber
For gut health, check whether the powder includes named probiotic strains or fiber. Most greens powders provide little fiber compared with whole vegetables.
Heavy metals and testing
Because greens are plant-based, trace heavy metals are worth considering. Favor brands that publish third-party test results or carry an independent certification.
Vitamin overlap and medications
Many greens powders contain vitamins and minerals, including vitamin K. Check for overlap with your multivitamin, and talk to your doctor if you take blood thinners.
Price per serving
Greens powders vary widely in price. Compare cost per serving, not per tub.

Frequently asked questions

Do greens powders actually do anything?

They can help fill nutrient gaps, especially vitamins and minerals, for people who don't eat many vegetables. Research on greens powders as a category is limited, and many studies are small or brand-funded. They're a supplement to a good diet, not a substitute for one.

When is the best time to take greens powder?

Many people take it in the morning, simply because it's easy to remember. If it upsets your stomach, take it with food. Follow the serving size on the label.

Do greens powders help with weight loss?

No greens powder causes weight loss on its own. A low-calorie greens drink may help some people build healthier habits, but weight loss comes from an overall calorie deficit. Be wary of greens products marketed with dramatic weight-loss claims.
