A serving is not a standard unit

One labeled serving across these five products ranges from 5.5 grams to 90 grams, so cost per serving alone is misleading. Cost per gram puts every product on the same scale: here it runs from $0.04 to $0.41 per gram.

Prices are the listed one time price recorded on the date shown in each review, and they change often. Cost per gram divides the listed price by the total grams in the container, which is serving weight times servings, never typed by hand. It is the only row here where a large meal replacement and a small greens scoop are measured the same way.

Why grams matter

A “serving” is not a standardized amount. One brand's serving may be much larger or smaller than another's. That is why Greens Powder Guide compares price per serving and price per gram, along with nutrient density and ingredient quality.

We buy what we review

Products are purchased at retail. We do not accept samples, sponsorships, or paid placements.

Scores are opinions, clearly labeled

Every score is an editorial judgment based on the published rubric. We do not present opinion as measurement.

Unverified means unverified

When we cannot cite a price, a serving count, or a facts panel, the field reads not publicly verified and the criterion is withheld from the score.

Each review states what the label discloses, what it leaves out, and who the product suits. Same fields, same order, every time.

Visual comparison

Cost per gram, not cost per day

A labeled day ranges from a 5.5 gram greens scoop to a full meal, so cost per serving alone misleads. These bars compare cost per gram of actual product, which puts the five launch reviews on the same scale.

See the full comparison

Cost per gram is the listed price divided by total grams in the container, where total grams is serving weight times servings. Products missing a citable input show not publicly verified on the comparison page.

Category winners

Who leads, and on what

Category leaders are decided by the recorded fields, using the same calculation for every brand. Every criterion counts toward the score, and one that is not publicly verified is held at a neutral baseline of 5 out of 10 rather than removed, so each score is shown with the share of the rubric resting on verified data.

Methodology

How a product earns its score

Four criteria, fixed weights, applied the same way to every product. Price, quantity and quality stay separate, and product type is always shown as context.

Ingredient quality
18%
Built from verifiable label attributes: organic certification carries the most weight, followed by whole food sourcing, named ingredients rather than grouped blends, and the absence of artificial sweeteners, colors and flavors. A long ingredient list earns nothing on its own, and marketing language is never read. Only the attributes we have verified are averaged, so a product is never credited or penalized for a blank field.
Nutrient density
15%
Nutritional substance inside the grams delivered, read from the published nutrition panel: protein, fiber, essential fats and low added sugar per 100 g of powder, with naturally occurring micronutrients credited ahead of isolated fortification. Measured as a density so it never repeats the quantity credit in serving grams. Meal replacement completeness is credited only where the verified panel supports it. No therapeutic or medicinal benefit is assumed.
Label transparency
14%
How much of the formula the published label discloses, from full per ingredient amounts down to grouped blend totals.
Value per gram
18%
Listed price divided by the grams of powder in the container, so cost is measured against the amount of product you actually receive rather than against a label serving that could be a small scoop or a full meal.
Product per dollar
5%
Total grams in the container per dollar spent. The same measure as value per gram read from the buyer's side, showing how much product a fixed budget brings home.
Serving grams delivered
5%
Grams delivered in one label serving, scaled inside the product type so a greens scoop is never measured against a meal serving. Grams alone are not treated as nutrition: where a nutrition panel is verified, the grams score is adjusted by the measured nutrient density, so a large serving built on starch or sugar cannot outscore a smaller nutrient dense serving. This records quantity delivered, not cost, which value per gram handles separately.
Price per serving
5%
Listed price divided by the labeled serving count. Held at a low weight because a labeled serving is not a standard unit across product types.
Testing and certifications
10%
Finished product third party testing published by an identifiable source. A manufacturer statement is not treated as an independent result.
Packaging protection
10%
How well the container protects the powder from light, oxygen and moisture. Amber or dark glass, foil laminate, and high barrier mylar with oxygen or moisture control score highest. Aluminum, opaque plastic, or a plastic tub score in the middle. Clear plastic, vinyl, or other low barrier films score lowest. Recyclability is recorded but treated as secondary to preservation. Packaging that is not publicly verified is withheld from the score rather than assumed, and the same standard applies to every brand.
