How the clean score works

No setup needed, and strict: a full 100 needs every additive group clear and a verified organic claim (animal foods also need a verified grass-fed or pasture-raised claim; wild seafood and salt, which have no USDA organic standard, are scored without the organic points, and plant-based milks, cheeses and proteins without the feeding claim). Points: the nine additive groups (seed oils, artificial dyes, MSG, artificial sweeteners, carrageenan, artificial preservatives, hydrogenated oils, corn syrups, banned-abroad additives) share 60 points equally — not found earns a group’s full share, “may contain” earns half, listed earns 0; a verified organic claim is worth 25; a verified grass-fed or pasture-raised claim is worth 15 and counts only for animal foods. No claim, or an expired or unverified claim, earns nothing, so products without those claims cannot reach 100. Unverified or expired ingredient labels receive no score. Equal scores are equal. Ties are ordered by brand. Unknown and stale evidence never passes “Only show matches.” Producer claims and prices do not affect this score. This is not a nutrition, allergy, or safety rating.

Choosing protein powders: what to check before you buy

Choose the protein source first, then compare grams of protein for the stated scoop weight. Whey, pea, rice and blended powders use different recipes; each flavor can have its own sweeteners, gums and other additions.

Confirm what any testing certification covers and whether a report matches the product or batch you are buying. An ingredient score does not establish heavy-metal levels, banned-substance testing or suitability for a particular diet.

What the labels on this shelf show

We track 126 products from 25 brands on the protein powders shelf. 66 have a complete, current ingredient label on record (52%), which is what lets us score them. The other 60 stay unscored until the maker publishes a full label; a missing label is “not yet”, never a pass.

Of the 66 scored labels, 49 (74%) list none of the nine additive groups we check. The group that appears most is artificial sweeteners, listed on 14 labels, followed by seed oils on 6. 6 scored products carry a verified organic claim, which adds points. Scores here run from 40 to 100, and the typical label lists 6 ingredients.

What to skip, and why

These scored products list at least one group on their current label. That is the clearest reason to pass if you are avoiding those ingredients.

The 60 products without a verified label are a separate “not yet”: we have no recorded ingredient list to check, so we cannot say they are clean or flagged.

What to verify on the label

Match unflavored protein with unflavored protein; flavored formulas can add ingredients. Check concentrate versus isolate and the exact container size. One-time and subscription prices differ. Confirm your selection before checkout.

Organic is not an additive verdict

Confirm the certification for the exact powder. Then check oils, gums, flavorings, and sweeteners independently in its ingredient list. The same brand can offer formulas with different ingredients and certification status.

Orgain: product certifications and testing

Make a fair flavor comparison

The sources above deliberately name their variants. Orgain’s linked formula is chocolate; Garden of Life’s is unflavored. They are research starting points, not a like-for-like taste or nutrition ranking. Choose matching flavors before comparing a basket.

Check the formula you have in hand

These formulas are not yet ingredient-verified records in our saved product library. Review the complete current ingredient statement on the linked manufacturer page. A product’s certification information alone does not create a clean result.

Your preferences, explained

The clean score is strict and needs no setup: nine additive groups not found in a current ingredient statement, plus a verified organic claim (and a grass-fed or pasture-raised claim for animal foods), are needed for 100; a possible match earns half and a missing claim earns nothing. Missing or expired evidence stays unknown. It does not assess nutrition, allergies, contaminants, or safety.
