Our mission is to
Assess the effects of compounds
without the use of regulatory animal tests
What we offer
Assessment of toxicity and health effects of compounds through a combination of wet lab testing and data science solutions
Identification of the mode of action by which your product affects the human body (mechanisms / Adverse Outcome Pathways)
Assisting you in selecting the most suitable -regulatory animal free- test system(s) for studies towards compound activity
Investigating your complex compounds (among others: volatile, UVCBs, plant extracts, and compound mixtures)
Assisting you with tailor-made solutions for your research approach
Our servicesVivaltes offers a combination of data science and wet lab testing with the non-mammalian organism Caenorhabditis elegans (C. elegans) to assess adverse and/or positive health effects of compounds.
Uniquely, Vivaltes’ systems allow analysis of combinations of active compounds and substances with unknown or variable composition, complex reaction products, or of biological materials (UVCBs).
Originally developed for developmental and reproductive toxicology (DART) testing, our wet lab portfolio now also includes: neurotoxicity, oxidative stress, fat accumulation, eating behaviour, associative learning, energy levels, and autophagy. Toxicity and beneficial health effects can be tested concurrently, with the possibility to start from a disease model.
Our data science portfolio includes evolutionary cross-species conservation mapping, phenomics, and pathway mapping.
Contact Vivaltes directly to discuss options for tailor-made solutions.
Unlike in vitro tests with cells, living organisms like C. elegans have cells and organs inside their body which communicate with each other, for example by neurons but also hormones and other signalling molecules.
Our strategy allows us to pre-screen compounds to identify health activities (toxicity and/or pharmaceutical effects), to identify synergism between compounds, and to discover how compounds influence a body. Vivaltes contribution is to assist with the selection of the most promising compounds to fill your product development pipelines. In addition, knowledge on how compounds cause their effects helps to identify (new) compound health activities, can improve compound/drug combinations, serves as supportive proof for regulatory acceptance.
Using data science, Vivaltes can now go beyond exploratory lab testing. We are able to extract (e.g. mammalian) phenotypes from scientific literature and internal reports, and identity the involved mechanism/mode of action (like Adverse Outcome Pathways). Accordingly, we can predict expected phenotypes for the new test methods, like for the in vivo test organisms C. elegans and zebrafish. Our data science pipeline allows us to perform more focused confirmatory lab testing.
Moreover, we are developing a data platform which maps the health effects of herbs and its compounds, including its biological mechanisms. This database assists agricultural companies in developing new health beneficial products and marketing their activities.
Finally, in collaboration with academic and industrial partners, we are developing an online database that contains physicochemical and pharmacokinetic properties of chemicals. This database will be able to assist customers with reliable testing and allow for quantitative in vitro to in vivo extrapolations (QIVIVE).
The Experimental ModelVivaltes’ core strength is the experimental model organism C. elegans, a 1-mm long transparent nematode, belonging to the animal kingdom. However, C. elegans falls outside the definition of animals as described in the animal testing law, and experimental work is as such considered animal-test free. C. elegans was first used as a model organism in 1963 and the acquired knowledge made an invaluable contribution to the fields of developmental biology and genetics. C. elegans has proven its applicability in predicting compound-induced health effects relevant to humans, evident from the increasing number of publications.
The C. elegans body plan
Core components of our services
- C. elegans is a multicellular organism, it has neuronal, motor, digestive, and reproductive systems, endocrine signalling, and sensory/behavioural responses to stimuli, which are not present in cell and tissue cultures.
- The organism has been extensively studied since 1963, there is thus a large body of knowledge to make use of.
- Humans and C. elegans have a common ancestor, thus essential genes and key biological pathways of C. elegans and humans are conserved.
- Testing C. elegans is cost-effective and allows for rapid turn-around of experiments. An advantage of the use of C. elegans as a test system is that it allows for multiple concentrations and exposure times to be assessed simultaneously. Multigeneration and progeny testing can be done in weeks rather than years due to its rapid lifecycle.
- Multiple types of toxicity ranking screens have demonstrated a high correlation of phenotypic endpoints in C. elegans to rat LD50s, with C. elegans data and mouse data predicting toxicity ranking in rat equally well.
Our Core Purpose
To reduce the costs and the number of animal testing by the introduction of a Tier 1 phase of testing in experimental models with predictive power for effects in humans.
To select the most promising compounds for your product development pipeline by tailor-made solutions.
To understand how your compounds cause their effects in order to help improve compound/drug design procedure.
To reduce the cost and burden of animal testing by:
- Utilizing C. elegans nematodes as standard Tier 1 alternatives for animal testing.
- Extracting the relevant information from the wealth of knowledge within scientific literature using data science.
Our Core Values
- We strongly value authenticity and open communication.
- Our passion is to deliver the best service and improve product development pipelines.

Using Data Science to explore and predict
health effects of compounds and herbs
About UsVivaltes was founded by Dr. Marjolein Wildwater and Dr. Gerrit Keizer in 2016 as a result of a NC3R-funded project. Their goal was to reduce animal research when carrying out toxicological and medicinal studies by offering C. elegans wet lab testing. Since then, Vivaltes has grown into a successful company with an enthusiastic team who share their vision of reducing animal testing, and with several long-term (inter)national customers. Expanding beyond wet lab testing, Vivaltes has won funding for several ambitious projects, which has helped develop their data science solutions. With strong roots in the scientific community, Vivaltes closely collaborates with academic institutions (such as University of Applied Sciences Utrecht and Utrecht University), which helps them to stay on top of scientific advances.

Hot peppers: a new weapon in the fight against obesity?
December 8, 2018
Hot peppers contain a substance that causes you to burn more fat. In that way, one can continue to eat the same and still lose weight. In America a medicine is being made from hot peppers. Dutch researchers want to make a food supplement or even a whole new pepper variety. Vivaltes is working on the subject with a team of researchers.
October 15, 2018
The goal of the TOX FLOW project is to set up a test method for animal test-free testing of effects of complex substances on reproduction and development (also called developmental and reproductive toxicology (DART)). Partners in this project are HU, IRAS-UU, WUR, RIKILT, Pamgene.
NC3Rs Crack-It Phase I
