Greens Powder Labels: Proprietary Blends, Serving Size and Probiotics

A greens powder label usually lists a long run of plant names, and almost none of them have their own amount. That is not an error on the label. It is how a “proprietary blend” is allowed to be declared. This explainer covers what is special about greens powder labels: what a blend weight tells you, what it leaves out, how the serving size fits together, and how a probiotic line shows up in a greens product. For the Supplement Facts panel in general, start with our guide to reading a supplement label. For CFU counts and strain names, see our probiotic label explainer. Our worked example is the one greens powder we carry, Amazing Grass Super Greens, Original.

How we wrote this: the Amazing Grass details come from the Supplement Facts image and the “Other ingredients” image on the Amazing Grass product page, read in October 2026. The labeling rules come from the federal regulation on dietary supplement labels, 21 CFR 101.36, and the sugar rounding rules in 21 CFR 101.9. We did not test the product and we have not seen the physical tub. Labels change, so check the one on the container you buy.

What the rule says about proprietary blends

Section 101.36(c) lets a maker group several ingredients under one name, such as “Proprietary Blend” or a branded name, and list them together. In plain terms, the rule asks for four things:

• A name for the blend, which can be “Proprietary Blend” or any “appropriately descriptive term or fanciful name”. That is why you see names like “Green Food Blend” instead of the word “proprietary”.
• One total weight on the blend’s line. That number is the combined weight of the “other dietary ingredients” inside it, not of each one.
• The ingredients in descending order by weight, indented under the blend name. The first one listed is present in the largest amount, the last in the smallest, but no individual amounts are required.
• A “Daily Value not established” symbol next to the blend, because plant ingredients like wheat grass have no Daily Value.

One detail matters for greens powders: under 101.36(c)(1), vitamins and minerals that sit inside a blend still have to be declared with their own amounts in the usual way. So a blend can hide how much spinach is in a scoop, but it cannot hide how much vitamin K the scoop provides. Those amounts appear in the upper part of the panel with a % Daily Value.

The worked example: Amazing Grass Super Greens, Original

The Supplement Facts image on the brand page lists a serving size of 8 g (about 1 scoop) and 30 servings per container. Below the nutrient rows, it lists four lines that work like blends:

• Amazing Grass Green Food Blend, 5.4 g: organic wheat grass, organic barley grass, organic alfalfa grass, organic spinach, organic spirulina, peppermint leaf, organic chlorella (cracked cell-wall), organic broccoli.
• Amazing Grass Antioxidant Blend, 1.4 g: acerola cherry extract, organic rose hips, organic pineapple, organic carrot, organic goji berry, green tea leaf extract, organic açaí berry, organic beet root, raspberry, organic maca root.
• Fiber Blend, 620 mg: organic flax seed, apple pectin.
• Bacillus subtilis DE111 (1 Billion CFU), 10 mg.

Each of these lines carries the “Daily Value not established” symbol, as the rule requires. The word “Antioxidant” here is the blend’s name on the panel. It is not a measurement, and the label does not give an antioxidant amount.

What the blend weights tell you

• Order. Wheat grass is listed first in the Green Food Blend, so by the rule it is the largest ingredient in that blend. Broccoli is listed last, so it is the smallest of those eight.
• Totals. The Green Food Blend weighs 5.4 g per scoop, so it makes up most of the 8 g serving.
• How the scoop adds up. By our arithmetic, the four lines total about 7.43 g (5.4 g + 1.4 g + 0.62 g + 0.01 g). The rest of the 8 g scoop is the “other ingredients”, covered below.

What the blend weights do not tell you

• The amount of any single plant. The label does not say how much spinach, spirulina or broccoli is in a scoop. Eight ingredients share 5.4 g, but the split could be very uneven.
• A minimum for the smaller ingredients. An ingredient near the end of a list is present, but the label gives no floor for it.
• How a powder compares with the food itself. A gram figure on a dried powder is not a serving of the fresh plant, and the label makes no such comparison. A greens powder is a supplement, not a substitute for vegetables.

If you want ingredient-by-ingredient amounts, look for a label that lists each ingredient on its own line with its own weight. That is a choice some makers take; the rule does not require it.

The nutrient rows above the blends

Because of 101.36(c)(1), the top of the panel gives real amounts with a % Daily Value. Per 8 g scoop, the Amazing Grass image lists:

• Calories 30; total carbohydrate 5 g (2% DV); dietary fiber 2 g (7% DV); total sugars less than 1 g; includes 0 g added sugars; protein 2 g
• Vitamin A 60 mcg (7% DV), vitamin C 90 mg (100% DV), vitamin K 69 mcg (57% DV)
• Calcium 30 mg (3% DV), iron 1.7 mg (9% DV), sodium 20 mg (1% DV), potassium 130 mg (3% DV)

These rows are the most concrete numbers on a greens powder label. If you take other supplements, this is the part to add up, because vitamins A and K and iron can also appear in a multivitamin. Our supplement label guide explains how % Daily Value works.

“Less than 1 g” sugars and “0 g” added sugars

Small amounts on these lines are rounded. Under 21 CFR 101.9(c)(6), a serving with less than 0.5 g of sugars may be shown as zero, and amounts under 1 g can be shown as “less than 1 g”. So “0 g” on a label means a rounded figure, not necessarily none at all. That is worth knowing because the Amazing Grass “Other ingredients” image lists fructose (see below). Reading both parts of the label together gives you the full picture.

Other ingredients

Below the panel, the brand’s image lists the other ingredients as fructose, inulin (chicory root fiber), natural flavor and silica. These are not part of the blend weights. They are the remainder of the scoop: sweetener, a fiber ingredient, flavor and an ingredient that helps powder flow. If you avoid any of these, this list is where you will find them, not inside the blends.

The probiotic line in a greens powder

Many greens powders add a probiotic, and it usually sits as its own line rather than inside a blend. On the Amazing Grass panel it reads Bacillus subtilis DE111 (1 Billion CFU), 10 mg. That line gives the strain name, a weight and a count, which is more detail than the blends above it. The image does not say whether the count holds at the time of manufacture or through the date on the tub. Our probiotic label explainer covers why that wording matters and why milligrams do not convert to CFUs across strains.

What “organic” means on a blend list

On a greens panel, “organic” is attached to each ingredient name, so read it ingredient by ingredient. On the Amazing Grass image, most names carry “Organic”, while peppermint leaf, acerola cherry extract, green tea leaf extract, raspberry and apple pectin are listed without it. Front-of-pack wording is a summary; the ingredient lines are the detail. For what the organic seal itself covers, see our Non-GMO Project vs USDA Organic guide.

A quick checklist for any greens powder label

1. Serving size in grams. Compare products per gram, not per scoop, since scoops differ.
2. Blend names and totals. Note how many blends there are and what each weighs.
3. The first two or three ingredients in each blend. They make up the largest share.
4. The nutrient rows. These are the only per-nutrient amounts, so check them against anything else you take.
5. Any probiotic line. Look for a strain name, a count and whether the count is stated through a date.
6. Other ingredients. Sweeteners, flavors and fibers are listed here.
7. Allergen and caution text. Read the container itself for allergen statements and warnings, such as advice to check with a doctor if you are pregnant, nursing or taking medication.

FAQ

Is a proprietary blend allowed to leave out ingredient amounts?

Yes. Under 21 CFR 101.36(c), a blend must show its total weight and list its ingredients in descending order by weight, but individual amounts of the plant ingredients are not required. Vitamins and minerals inside a blend must still be declared with their amounts.

Does the first ingredient in a blend make up most of it?

It is the largest single ingredient, but the label does not say whether it is most of the blend or just slightly ahead of the next one.

Why does the panel show a “†” next to the blends?

That symbol points to the footnote “Daily Value not established”. Plant ingredients and probiotics have no Daily Value, so the rule asks for this symbol instead of a percentage.

Why do the blend weights not add up to the serving size?

The serving also includes the other ingredients listed below the panel. On the Amazing Grass label, the blend lines total about 7.43 g of the 8 g scoop.
