Comparison of Thresholds
This chart shows the four reference points used to evaluate heavy metal safety in supplements — and where Mikuna Pure Chocho Plant Protein lands. Bars are proportional to actual values.
Sources: FDA Interim Reference Level for Lead in food (2022, adults; Flannery et al., Regulatory Toxicology and Pharmacology); California Office of Environmental Health Hazard Assessment (OEHHA) Prop 65 MADL for lead (0.5 mcg/day; 27 CCR § 25805); Consumer Reports protein powder study (October 2025).
Plant Protein Category range derived from Consumer Reports' October 2025 investigation of 23 protein supplements. Low-end reflects the 0.5 mcg/day Prop 65 MADL benchmark used by CR; high-end (7.7 mcg/day) reflects the highest plant-based product tested. Range is specific to the CR sample and may not represent the full plant protein market.
Mikuna value based on Eurofins Scientific Certificate of Analysis CPP5LBPC (Nov 2025), Lead (Pb) reported <0.010 mg/kg via method QD06S (Mwd-ICP-MS, J. AOAC vol. 90 (2007) 844–856 Mod), calculated for a single 39g serving of Pure Chocho Plant Protein (<0.39 mcg per serving). Lead content measured below the laboratory's limit of quantification (LOQ). Subject to natural variability between lots — most recent COA always available above.
When the Industry
Failed the Test,
We Stepped Up.
Consumer Reports tested 23 protein powders and found that more than 70% contained lead at or above their level of concern. Mikuna was not named in the report — but we're publishing our results anyway. Because transparency shouldn't be optional.
Mikuna results independently verified by Eurofins Scientific.

Mikuna Pure Chocho Plant Protein tests below the Prop 65, FDA limits, and Consumer Reports level of concern for all heavy metals tested. This includes lead, cadmium, arsenic, and mercury. Testing conducted by Eurofins Scientific using ICP-MS methodology, the most sensitive and accurate method available. See the lead comparison chart ↑
Independent third-party testing confirms that lectins have not been detected in any of our products. Lectins are carbohydrate-binding proteins commonly found in legumes known to cause bloating and digestive discomfort — the reason most plant proteins cause GI issues. Chocho's proprietary debittering process removes them entirely.
We test for over 50 organochlorine, organophosphate, and pyrethroid pesticides using advanced multi-residue screening. All results show no presence or detection across every tested compound. Chocho grows naturally at 11,000–14,000 ft in the Andes — its natural alkaloids repel pests, making chemical pesticides unnecessary. Full COAs available below.
Gluten concentration tested negative (<5 ppm) using an immuno-chromatographic method. Our most recent testing shows results below 3 ppm, well below the FDA threshold of 20 ppm for gluten-free labeling. Chocho is naturally gluten-free.
Note: Our manufacturer handles various ingredients, and the risk of cross-contact may exist.
Oxalic acid (oxalate) is a naturally occurring plant compound found in most fruits, vegetables, nuts, and legumes. Oxalate content varies widely across plant foods and is influenced by variety, growing conditions, and preparation method.
Independent laboratory analysis shows Mikuna Pure Chocho Plant Protein contains <20 mg/kg of oxalic acid (approximately <2 mg per 100g). This result was reported below the laboratory's limit of detection via Eurofins organic acid profile method HEG7J.
Dietary context. The table at right shows published oxalate ranges for common plant foods drawn from peer-reviewed food composition research. Values in the scientific literature vary significantly due to natural variability in plant crops, so published ranges are given rather than single figures. This information is compositional reference only.
This page is not medical advice. People with a history of kidney stones, hyperoxaluria, or other conditions where oxalate intake is clinically relevant should consult their physician or a registered dietitian before making dietary changes. Oxalate absorption depends on many factors beyond raw content, including calcium co-ingestion, preparation method, and individual physiology.
| Food | Oxalate (mg / 100g) |
|---|---|
| Spinach (raw) Variety-dependent | ~330.00–2,350.00 [1][2] |
| Rhubarb (raw) | ~860.00–1,235.00 [3] |
| Swiss chard (raw) | ~645.00–964.00 [3] |
| Almonds (roasted) | ~469.00 [3] |
| Sweet potato (raw) | ~240.00 [3] |
| Soybeans (boiled) | ~56.00 [3] |
| Blueberries (raw) | ~2.90 [3] |
| Mikuna Pure Chocho Measured, Eurofins | <2.00 [4] |
| Banana (raw) | ~0.20 [3] |
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, And Polyols — a group of short-chain carbohydrates that can be poorly absorbed in the small intestine and fermented by gut bacteria. In sensitive individuals, FODMAPs may contribute to digestive symptoms.
Independent laboratory analysis of Mikuna Pure Chocho shows the two primary oligosaccharide FODMAPs present in lupin — raffinose at 0.002% and stachyose at 0.010% by weight. Fructose, galactose, glucose, lactose, maltose, and sucrose were reported below detection (0.000%).
Scope of testing: This panel covers the disaccharides and the raffinose-family oligosaccharides characteristic of legumes. It does not evaluate fructans or polyols. Mikuna Pure Chocho is not Monash University FODMAP Certified.
For people with IBS or diagnosed FODMAP sensitivity: individual tolerance varies. This page is not medical advice. Consult a registered dietitian or your physician before changing your diet.
| Parameter | Result |
|---|---|
| Fructose | 0.000 % |
| Galactose | 0.000 % |
| Glucose | 0.000 % |
| Lactose | 0.000 % |
| Maltose | 0.000 % |
| Raffinose | 0.002 % |
| Stachyose | 0.010 % |
| Sucrose | 0.000 % |
Organic acids are naturally occurring compounds found in virtually all plant foods. They contribute to flavor, act as natural preservatives, and play a role in the plant's own metabolism. This panel measures 13 common organic acids in Mikuna Pure Chocho as part of our compositional transparency.
The three quantifiable organic acids in Pure Chocho are acetic acid at 318 mg/kg, formic acid at 113 mg/kg, and citric acid at 21 mg/kg. All other acids in the panel were reported below the laboratory's limit of detection. These values are consistent with naturally occurring organic acid content in legume-based plant proteins.
Scope of testing. This panel is compositional in nature — organic acids are not contaminants, and there are no regulatory safety thresholds for these values. The results are published for full transparency rather than as a safety claim.
Note on matrix effects: for pyruvic and succinic acid, Eurofins reported that the limit of detection was raised due to the food matrix. This is a standard observation for complex plant-derived samples.
| Parameter | Result |
|---|---|
| Oxalic acid | <20 mg/kg |
| Citric acid | 21 mg/kg |
| Pyruvic acid Matrix-adjusted LOD | <4 mg/kg |
| Malic acid | <25 mg/kg |
| Quinic acid | <100 mg/kg |
| Succinic acid Matrix-adjusted LOD | <98 mg/kg |
| Glycolic acid | <50 mg/kg |
| Lactic acid | <40 mg/kg |
| Acetic acid | 318 mg/kg |
| Formic acid | 113 mg/kg |
| Propionic acid | <50 mg/kg |
| Pyroglutamic acid | <50 mg/kg |
| Butyric acid | <50 mg/kg |
Microbiological testing evaluates whether a food product is free from harmful bacteria, mold, and other microorganisms that could pose a food safety risk. Every production lot of Mikuna Pure Chocho Plant Protein undergoes a full microbiological panel before release.
Our panel covers the six parameters most relevant to dry plant-based protein powders:
- Total Aerobic Plate Count — overall microbial load
- Yeast & Mold — indicators of spoilage organisms
- Coliforms — general hygiene indicator
- E. coli — fecal contamination indicator
- Staphylococcus aureus — pathogen screening
- Salmonella — pathogen screening (tested for absence per 25g)
Testing is conducted by accredited third-party laboratories using industry-standard methods. Full microbiological results for recent production lots are available in our public Certificate of Analysis repository.
Microbiological specifications for dry plant-based dietary supplements are referenced against industry guidance, including United States Pharmacopeia (USP) General Chapter <2021> for microbial enumeration in nutritional and dietary supplements.
