Radish is a reasoned choice.
Radish microgreens contain glucosinolates and other measured plant constituents. Their profiles vary across cultivars and growing conditions. Tilahun et al., 2023 Mlinarić et al., 2023

Why radish matters—and what the research actually says.
Radish microgreens have a distinctive plant chemistry, and several preparations have produced measurable signals in cancer-cell models. This page follows those signals from the plant to the laboratory—and stops where the evidence stops.

The short answer
Three things the evidence allows us to say.
The page separates established plant composition, laboratory observations and product-specific conclusions. They are not the same kind of evidence.
Laboratory activity has been observed.
Radish-containing preparations have changed viability, proliferation, apoptosis-related markers or cell behaviour in several cancer-cell experiments. de la Fuente et al., 2020 Truzzi et al., 2021
The product remains food, not cancer therapy.
No direct study has tested the finished Only Plants formulation, and no human cancer trial has tested microgreens as prevention or treatment. The cell evidence supports investigation, not a medical claim.
Why radish?
A whole young plant with measurable chemistry.
Only Plants currently contains 50% dried radish microgreens. Radish belongs to the Brassicaceae family, alongside broccoli, mustard and cabbage. Studies of radish microgreens have measured glucosinolates, amino acids, minerals, vitamin C, phenolics, flavonoids and pigments; the quantities and relative profiles depend on cultivar and growing conditions. Tilahun et al., 2023 Mlinarić et al., 2023
Research on radish sprouts also reports characteristic glucosinolates and isothiocyanates, but sprouts and microgreens are different developmental stages. Sprout findings therefore provide biological context; they are not silently treated as measurements of the Only Plants ingredient. Hanlon & Barnes, 2011
What this means: radish was not selected because of a single “miracle molecule.” It is an edible young plant with a documented and variable chemical profile worth characterising in the actual product.
Glucosinolates in plain language
The compound in the plant is only the beginning.
Glucosinolates are sulfur-containing compounds used by Brassicaceae plants in their defence chemistry. They contribute to the sharp, mustard-like character associated with radish and related vegetables. Bhaswant et al., 2023
When plant tissue is cut, crushed, chewed or milled, the enzyme myrosinase can convert glucosinolates into breakdown products, including isothiocyanates. Processing, storage, digestion and the gut microbiome can all influence which products are formed and become accessible. Bhaswant et al., 2023
That is why “radish contains glucosinolates” is not yet an answer about what a person receives from a dried capsule. The finished material must be measured, and digestion-aware studies are needed to understand release and transformation. de la Fuente et al., 2020 Sosnowska et al., 2025
01Present in radish
Composition studies identify compounds in defined plant material.
02Changed by preparation
Cutting, drying, milling and storage can alter the starting material.
03Transformed in digestion
Enzymes and digestion affect release and conversion.
04Available to the body
Bioaccessibility and absorption are separate questions.
05Relevant to Only Plants
Only finished-product testing can support product-specific conclusions.
Direct cancer-cell evidence
What four radish-relevant studies actually observed.
These are laboratory experiments, not trials in people. Each card identifies the material, model, observation and the reason it cannot be transferred directly to Only Plants.
de la Fuente et al. (2020)
Studied: bioaccessible fractions after simulated digestion of fresh broccoli, kale, mustard and radish microgreens; Caco-2 colon cancer cells and CCD18-Co normal colon cells.
Observed: modest reductions in Caco-2 viability plus redox, cell-cycle and apoptosis-related changes. Radish showed a statistically greater effect in cancer than normal cells in that experiment.
Boundary: pooled fresh microgreens, one cancer model, short exposure and no dried finished formulation.

Studied: aqueous extracts of five microgreens grown under different lights; two Ewing sarcoma cell lines, 2D cultures, 3D spheroids and L929 fibroblasts.
Observed: effects depended on species, light, model and dose. Red Rambo radish affected one 3D model, while some ordinary radish conditions did not show a uniform beneficial direction.
Boundary: an aqueous extract captures only part of the food matrix, and 3D results were narrower than 2D screening.

Studied: mustard and Thai rat-tailed-radish young plants, including material grown from plasma-treated seed; A549 lung cancer cells.
Observed: the authors reported concentration-dependent effects together with apoptosis-, cell-cycle- and migration-related measurements.
Boundary: a different radish type, experimental plasma treatment, no matched normal-cell comparator and no digestion step.
Read the paper · DOI 10.15835/nbha50212751 ↗Tiras et al. (2025)
Studied: methanolic red-radish and parsley microgreen extracts; MEC-1 and HG-3 chronic lymphocytic-leukaemia cells.
Observed: red-radish extract reduced proliferation in MEC-1 only at a high reported concentration, but increased proliferation in HG-3 under the tested conditions.
Boundary: no normal-cell comparator, very high concentrations and contradictory results across two cancer lines.

A real signal—but not one simple answer.
The research is interesting precisely because preparation, cultivar, dose and model change the result. “Microgreens” is not one uniform experimental material.
Cells can respond.
Multiple studies report changes in viability, proliferation, cell cycle, apoptosis-related markers or migration.
Materials are heterogeneous.
Fresh digests, aqueous or solvent extracts, young plants and engineered nanoparticle preparations are not equivalent.
Human relevance is unknown.
Laboratory concentrations and exposures cannot be assumed to occur after consuming a food product.
Collective interpretation: radish and other microgreen preparations provide a credible research signal. The evidence does not establish cancer prevention, treatment, human safety at experimental doses or effectiveness of the Only Plants formulation.
What this means for an Only Plants user
What you are choosing today.
The legitimate present-day story is an ingredient and format story, not a promise of a future medical effect.
Dried food material.
Only Plants uses dried and milled radish and sunflower microgreens, not an isolated drug molecule or concentrated pharmaceutical extract.
Radish has a scientific reason to be here.
Its measured glucosinolate profile and broader plant composition make it a meaningful material to select, characterise and study.
Designed for routine use.
The capsule provides a measured amount of dried young plant material in a convenient food format.
No borrowed cancer promise.
Findings from extracts, digests or other radish varieties are not presented as proof about the finished Only Plants product.
Only Plants can be chosen for what it is now: a convenient whole-plant food format with a deliberately selected radish-based ingredient. The cancer-cell literature explains why the ingredient is scientifically interesting—not what the product will do in a person.
From published research to product knowledge
Three questions that genuinely matter next.
These questions do not sell the product. They define the shortest responsible path from general radish evidence to knowledge about the material people actually consume.
What is in the finished powder?
Measure key compounds in the actual radish, sunflower and final mixture.
What survives until consumption?
Characterise stability after the proprietary low-temperature drying process, milling and storage.
What can digestion release?
Use a standardised digestion model before any cell comparison at realistic exposure levels.

Scientific and regulatory boundary
A research signal exists, but clinical relevance has not been established. No human cancer trial demonstrates that eating microgreens prevents or treats cancer, and no cancer study has tested the finished Only Plants formulation.
Only Plants is food—not a cancer-prevention or cancer-treatment product. Public wording about nutrition or health must be assessed separately under the EU nutrition and health claims framework.
