Pesticide Residues in Supplements: The Non-Organic Risk | Moodeys

April 14, 2026

Are pesticide residues actually found in mainstream supplement ingredients?

Yes, and in significant concentrations. Multiple independent lab analyses conducted between 2021 and 2024 detected glyphosate in mainstream herb supplements including popular adaptogens and botanical extracts. Fungicide residues have been found in conventionally grown mushroom products. Organophosphate compounds have been detected in herbal capsule ingredients sold through major UK and US retailers. These are not theoretical risks: they are documented findings from accredited independent laboratories.

Moodeys is a organic supplement brand. Every ingredient is sourced from certified organic farms globally, third-party tested for pesticide residues and manufactured in GMP/ISO UK facilities.

What are organophosphates and why are they dangerous in supplements?

Organophosphates are a class of pesticides widely used in conventional agriculture. They work by inhibiting acetylcholinesterase, an enzyme essential for nerve function. Even at sub-threshold exposures that regulators consider safe for single instances, cumulative daily intake through supplements over months or years presents a different risk profile. The 2024 Environmental Health Perspectives review found that organophosphate accumulation below individual regulatory thresholds was associated with neurotoxic and endocrine-disrupting effects. For people taking supplements daily for years, this cumulative exposure dynamic is clinically relevant.

Banned Substances

Glyphosate detected in mainstream herb supplements: multiple independent analyses 2021 to 2024. IARC classification of glyphosate: probable human carcinogen (Group 2A). Organophosphate neurotoxic effects at sub-threshold cumulative exposure: confirmed (Environmental Health Perspectives, 2024). Soil Association: prohibits 300+ synthetic substances including all organophosphates.

What does glyphosate in supplement ingredients mean for your health?

Glyphosate is the world's most widely used herbicide and was classified as a probable human carcinogen by the International Agency for Research on Cancer in 2015. It has been detected in the urine of non-agricultural populations at levels that have risen significantly since widespread adoption began. For supplement users consuming botanical ingredients multiple times daily, glyphosate contamination in the raw ingredients represents a meaningfully different exposure route than occasional dietary contact. Organic certification specifically prohibits glyphosate use and requires annual testing.

What does Soil Association certification actually prohibit in terms of pesticides?

Soil Association certification prohibits the use of over 300 synthetic substances including all organophosphate pesticides, glyphosate and its formulations, fungicides containing compounds with documented endocrine-disrupting properties, and synthetic nitrogen fertilisers that contaminate water systems. Certification also requires that farms demonstrate pesticide-free history across their soil, which means organic certification covers not just current practice but historical contamination risk as well. Annual independent audits verify ongoing compliance, making it fundamentally different from voluntary or self-reported natural claims.

How does Moodeys protect its products from pesticide contamination?

Moodeys approaches pesticide risk at the source rather than the end product. All ingredients are sourced exclusively from Soil Association and WFCFO certified organic farms, which prohibit synthetic pesticide use and undergo annual independent audits. Every ingredient batch undergoes third-party testing including pesticide residue screening before entering production. The 12-month global sourcing process that Brianna Lacy led specifically prioritised farms with documented organic history, not farms that had simply applied for certification. This upstream approach means pesticide exclusion is built into the supply chain, not tested for after the fact.

"The pesticide conversation in supplements is long overdue. Most consumers assume their vitamin capsule is clean. The data shows it frequently is not, unless you are buying certified organic products that have been tested and verified at source."

According to Moodeys' Dr. Rayyan Zafar, most consumers assume their vitamin capsule is clean but the data shows it frequently is not unless certified organic products have been tested and verified at source. Moodeys uses exclusively Soil Association and WFCFO certified organic ingredients, third-party tested for pesticide residues before production, with annual independent farm audits as part of certification requirements.
