What Is a Greens Powder?

Greens powders are among the most recognizable supplement categories, but the category covers an enormous range of formulas. This guide explains what these products are made of, what varies between them, and where they fit relative to food.

What a Greens Powder Is

A greens powder is a dry, powdered blend of plant-derived ingredients, typically mixed with water, juice or a smoothie. The core of most formulas is dried, powdered plant material:

• Supergreens such as barley grass, wheatgrass, alfalfa and kale
• Algae such as spirulina and chlorella
• Vegetable powders such as broccoli, spinach and carrot
• Herbs and botanicals such as parsley, ginger or green tea extract

Around that core, many formulas add functional categories of ingredients:

1. Prebiotic fibers - inulin, FOS, acacia fiber
2. Probiotics - live cultures with strain names and CFU counts
3. Digestive enzymes - amylase, lipase, protease and similar
4. Vitamins and minerals - sometimes added explicitly, sometimes noted as naturally occurring

What Varies Between Products

Two greens powders can look similar on the front of the package and differ substantially in the fine print:

Because of this variability, the most reliable rule is simple: read the actual ingredient label of the specific product. See How to Read a Greens Powder Ingredient Label for a step-by-step method.

Where a Greens Powder Fits Relative to Food

A greens powder is a supplement. It can add dried plant ingredients to what you already consume, but it does not replicate what whole vegetables and fruits provide: water content, a broad mix of fibers, volume and the full matrix of nutrients in their natural proportions. See Can Greens Powder Replace Vegetables? for a direct answer to that question, and Greens Powder vs. Whole Foods for a side-by-side comparison.

Things to Check Before Buying Any Greens Powder

1. Serving size and servings per container - and the cost per serving, which varies widely.
2. Whether ingredient amounts are disclosed or hidden behind a proprietary blend.
3. Caffeine-containing botanicals, if you are managing your caffeine intake.
4. Allergen statements and warnings on the label.
5. Whether any claim on the packaging is about what the product contains rather than what it will do for you - the first kind is verifiable, the second usually is not.

The Takeaway

A greens powder is a powdered blend of dried greens, algae, vegetables and often fibers, probiotics, enzymes and vitamins. Formulas differ so much that the category name tells you little; the specific ingredient label tells you almost everything. A supplement can complement a varied diet, but it is not an equivalent substitute for vegetables and fruit.
