Summary
KOS Organic Superfood Plant Protein Vanilla scores 52/100. The cleanest plant powder formula in Batch B — USDA Organic blend of pea, flax, quinoa, pumpkin seed, and chia, plus organic coconut milk, coconut sugar, stevia + monk fruit (no sucralose), digestive enzymes, and a fruit/veg micronutrient blend. Independent third-party lab testing (Consumer Reports, January 2024) detected 0.55 mcg lead per serving. Cadmium 1.26, arsenic 0.51, and trace mercury 0.01 mcg also detected. Owned by KOS Naturals.
At a glance
Contaminants 4
Source: Consumer Reports January 2024
Lead 0.55 mcg per serving Moderate
Detected at a moderate level — a meaningful fraction of health-based exposure limits. Worth factoring in if this product is used regularly. No safe level of lead exposure exists per CDC, AAP, and WHO; chronic ingestion is associated with lowered IQ, neurodevelopmental harm, and cardiovascular and kidney effects.
Independent third-party testing.
Cadmium 1.26 mcg per serving Moderate
Detected at a moderate level — a meaningful fraction of health-based exposure limits. Worth factoring in if this product is used regularly. Cadmium is an IARC Group 1 carcinogen that accumulates in the kidneys over a lifetime.
Consumer Reports January 2024 detected 1.26 mcg cadmium per serving.
Arsenic 0.51 mcg per serving Low
A low level of arsenic — present but modest; a sourcing-quality note rather than a safety concern at typical intake.
Consumer Reports January 2024 detected 0.51 mcg arsenic per serving.
Mercury 0.01 mcg per serving Trace
A trace amount of mercury — within the range expected from normal soil uptake/processing and below our concern threshold.
Independent third-party testing.
Key ingredients 16
Organic Pea ProteinNeutral
USDA Organic plant-based protein that's notably good for a legume but still less bioavailable than whey or other animal-source proteins, meaning more grams are needed to deliver the same usable amino acids for muscle protein synthesis. Naturally low in methionine, so it does not stand alone as a complete protein and is typically blended with rice. Organic certification controls pesticides and synthetic fertilizers but not soil-accumulated heavy metals — pea crops are well-documented lead and cadmium accumulators.

Whole-seed plant ingredient providing omega-3 ALA, lignans, and fiber plus a small protein contribution. Less bioavailable than whey and not a primary protein driver.

Pseudo-cereal plant protein with a relatively complete amino acid profile but still less bioavailable than whey or other animal-source proteins. Soil-grown so does not avoid heavy-metal accumulation.
See more about Organic Quinoa →Organic Pumpkin Seed ProteinNeutral
USDA Organic seed-based plant protein providing additional amino acid diversity in plant blends. Less bioavailable than whey and naturally low in lysine and threonine, so it does not match animal-source protein on a gram-for-gram basis. Pumpkin seeds are also a known cadmium accumulator from soil — a contributing factor to the cadmium detected here.

Whole-seed plant protein adding amino acid diversity, polyphenols, and omega-3 ALA. Less bioavailable than whey and contributes only a small fraction of the total protein dose — a whole-food positive but not a primary protein driver.

USDA Organic coconut milk powder for creaminess; provides medium-chain fats.

USDA Organic natural cocoa providing polyphenol antioxidants. Cocoa is also a known cadmium accumulator.

Plant-derived prebiotic fiber that supports gut microbiome diversity.

Less-refined sugar with a lower glycemic index than table sugar but still added sugar.

Plant-derived (acacia tree sap) prebiotic fiber that supports gut microbiome diversity.

Unrefined sea salt — a minimally processed, natural source of sodium and essential trace minerals, and a legitimate whole-food seasoning. Treated as a positive ingredient.

Plant-source-restricted natural flavor; somewhat better than unrestricted 'natural flavors' but specific composition still falls under FDA trade-secret rules.

Natural zero-calorie sweetener from the stevia leaf. No significant health concerns, but Scout treats all stevia forms as neutral — neither penalized nor counted as a beneficial ingredient.

Whole-food micronutrient and polyphenol blend; small total dose but a positive over synthetic vitamin fortification.

Plant-derived zero-calorie sweetener; safer than synthetic sweeteners and pairs well with stevia to balance aftertaste.
See more about Monk Fruit Extract →Digestive Enzyme Blend (Amylase, Protease, Lipase, Lactase, Cellulase)Good
Digestive enzymes that aid protein and carbohydrate digestion, reducing GI discomfort common with plant protein.
