Momentous 100% Plant Protein Chocolate
Summary
Momentous 100% Plant Protein Chocolate scores 36/100. Premium brand used by Olympic and pro athletes — NSF Certified for Sport, Informed Sport tested, no gums/fillers/stabilizers. Formula is genuinely clean: only 8 ingredients, no synthetic sweeteners, organic cane sugar instead of artificial sweetener. Uses traceable PURIS pea protein (US-sourced). But independent third-party lab testing (Consumer Reports, January 2024) detected 2.33 mcg lead per serving. Cadmium 1.95 and arsenic 1.61 mcg also detected. Notable contrast: Momentous's whey-isolate sibling (also in app) measured at 0.15 mcg lead — 15× lower. The contamination is the plant feedstock, not the brand's QC. Owned by Momentous (Live Momentous, Inc.).
At a glance
Contaminants 4
Source: Consumer Reports January 2024
Lead 2.33 mcg per serving High
Detected at a high level — at or above health-based exposure limits. Regular exposure at this level is a genuine health concern. No safe level of lead exposure exists per CDC, AAP, and WHO. Likely source: pea + brown rice protein agricultural feedstock. Notable contrast: Momentous's whey-isolate sibling product measures 0.15 mcg — 15× lower; the contamination is the plant feedstock, not the brand's manufacturing QC.
Independent third-party testing.
Cadmium 1.95 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. Likely source: PURIS pea protein.
Consumer Reports January 2024 detected 1.95 mcg cadmium per serving.
Arsenic 1.61 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. IARC Group 1 carcinogen. Likely source: organic brown rice protein.
Consumer Reports January 2024 detected 1.61 mcg arsenic per serving.
Mercury not detected Not detected
Not detected — below the laboratory's detection limit. This is the strictest possible result: no measurable amount was found.
Consumer Reports January 2024 reported mercury below the lab's threshold of detection — no mercury measurable in this product.
Key ingredients 8
PURIS® Pea ProteinNeutral
US-sourced (Minnesota/Iowa) pea protein with full supply-chain traceability — better than commodity pea protein. Like all pea protein, it is 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 is typically blended with rice protein. Pea crops accumulate lead and cadmium from soil — the suspected primary contamination route in this product.

USDA Organic plant protein commonly paired with pea to round out the amino acid profile. On its own, brown rice protein is naturally low in lysine and less bioavailable than whey, so a larger gram dose is required to deliver the same usable amino acids for muscle protein synthesis. Brown rice is also the most well-documented arsenic accumulator in the food supply — the suspected source of arsenic detected here.

Natural cocoa providing chocolate flavor plus polyphenol antioxidants. Notably, cocoa itself is also a known cadmium accumulator and may be a secondary co-source of the cadmium detected.

Real organic sugar at a low dose (2 g per serving) used in place of artificial sweeteners — a meaningful positive vs sucralose/saccharin/acesulfame K but still added sugar.

Proprietary flavor blend; can hide dozens of synthetic aroma chemicals and phthalate carriers under FDA trade-secret rules.

Sodium for flavor balance; minimal contribution to total sodium intake.

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.

Plant-derived zero-calorie sweetener; safer than synthetic sweeteners and pairs well with stevia to balance aftertaste.
