Food Supplements Purity Testing in NMN and Heavy Metal Screening


Swiss law defines dietary supplements as foodstuffs intended to supplement the normal diet. They consist of single or multiple concentrates of vitamins, minerals, or other substances with a nutritional or physiological effect and are marketed in dose form.

The law also makes a distinction between dietary supplements (for example low dose vitamin products and enriched foodstuffs) and medicinal products (for example high dose vitamin products and their claims of medicinal effects).

Many food supplements, nutritional additives and other non-regulated dietary supplements go through cycles of popularity. Biolytix observes these cycles through the different customer requests it gets. One particularly common question is to verify the purity content of Nicotinamide Mononucleotide or NMN.

Nicotinamide Mononucleotide (NMN) is often sold through internet marketplaces, with promises to slow down the pace of ageing and claims to promote a longer life. Because of high demand and cost of this compound, it seems that some untrustworthy companies have begun selling fake NMN supplements.


Testing Purity of NMN and the absence of Heavy Metals


We offer NMN purity analysis and strongly suggest to also test for heavy metals, to make sure that the product contains what it promises.

  • Nicotinamide mononucleotide Analysis (HPLC-MS/MS): 250 CHF /sample
  • Heavy Metal Screening: 350 CHF /sample

Biolytix AG can detect Xylella fastidiosa and produces kits on request

Xylella in Olive tree in South italy

Xylella fastidiosa causes major damage to cultivated plants in Europe, especially in Italy, Spain and France
– Real-time PCR analysis kits for Xylella fastidiosa available on request

Witterswil, 20 November 2019 – Xylella fastidiosa, a vector-transmitted bacterial plant pathogen, is currently causing major problems in parts of Europe. Xylella fastidiosa was first detected on olive trees in southern Italy in Europe in 2013. Since then, the pathogenic bacterium has also been reported in France, Spain and Germany.

In Salento in southern Italy, the pathogenic bacterium has led to the so-called “Olive Quick-Down Syndrome” (OQDS), which results in the death of the leaves and branches of the olive tree, so that the trees can no longer produce olive plants.

“Plant pathogens such as Xylella fastidiosa can have serious effects on the economy of entire regions, especially if the disease is transmitted to important crops,” says Dr. Ralf Seyfarth, CSO of Biolytix.

The speed and presentation of symptoms on the plant depends very much on the following factors: host plant species, the level of bacterial inoculum, the subspecies involved and even the specific recombinations within the same or different subspecies as well as climatic conditions. (see Agroscope Fact Sheet (in German): Das Feuerbakterium – Xylella fastidiosa)

Thanks to our team of dedicated scientists, we are able to offer an analytical method for the detection of Xylella fastidiosa. If Xylella is suspected and you want to make sure that it is not Xylella fastidiosa – contact us!

For analytical laboratories and institutes: We also manufacture Xylella fastidiosa real-time PCR analysis kits for all common PCR devices.

Accumulation of listeriosis cases in Switzerland

– Federal Office of Public Health informs: Unexplained accumulation of listeriosis cases
– Listeriosis is caused by the bacterium Listeria monocytogenes
– Biolytix routinely analyzes foods for Listeria monocytogenes

Witterswil, 18 October 2018 – Since mid-2018, the weekly statistics of the Swiss Federal Office of Public Health have shown an unusual increase in listeriosis cases. The bacterium Listeria monocytogenes is found almost everywhere in the environment and can lead to listeriosis in humans.

Transmission takes place through the consumption of contaminated food. Listeriosis is a rare infectious disease, but it can have severe consequences in immunocompromised individuals. In women who become infected with Listeria during pregnancy, it can also lead to infection of the child.

The sources of infection are animal foods such as meat, sausages, fish, raw milk and dairy products (e.g., soft cheeses), but also vegetable foods (e.g., precut salads or fruits).

Biolytix routinely analyzes various foods for Listeria monocytogenes and can offer qualitative and quantitative test methods.

The result is available within 3-4 days. If interested, send us your food samples using the order form attached below.

Detection of Listeria monocytogenes

Ethoxyquin in Fish Feed

Ethoxyquin in Fisch

Ethoxyquin is a Antioxidant that delays the oxidation of lipophilic Vitamins (Carotine, Xanthophylle, Vitamin A und Vitamin E). It was widely used for the preservation of fishmeal (especially feed for fish farms). Prior to its ban as a plant protection product, ethoxyquin was also used as a post-harvest treatment against tan in apples and pears.

In June 2017 the European commission has formally suspended the authorization for the antioxidant ethoxyquin (EQ) as a feed additive with the publication of Regulation (EU) 2017/962.

Biolytix can help check the Ethoxyquin values in fish feed and fish meat. The detection limits are extremely sensitive (µg/kg = parts per billion).

Detection Limits

Ethoxyquin + Ethoxyquin-Dimer: 2 µg/kg + 5 µg/kg
BHA (Butylhydroxyanisol / E320):  10 µg/kg
BHT (Butylhydroxytoluol / E321):  10 µg/kg

Spring is here, time to tidy the allotment garden


Spring is here and summer is around the corner. Time to clean up the allotment garden and sow the first salad and carrots.

However, caution should be exercised when applying pesticides. In Switzerland, up to 200 tonnes of pesticides are used annually for private purposes.

“We have often measured elevated pesticide levels in regional gardens.” says CEO Adrian Härri, “Unfortunately, hobby gardeners are often unaware of how many pollutants are in their soil.”

Biolytix analyzes the vegetables and soil for pesticides and heavy metals (lead, cadmium, copper and zinc) to make sure that the hard-working vegetables can be enjoyed without worry.

Adrian Härri, head of Biolytix, a company that conducts molecular biological and microbiological analyzes, repeatedly proves the poison in biofish.

“We have never had a sample that did not contain ethoxyquin,” says Härri. Anyone who thinks that the organic salmon is free of pesticides is wrong. “In fact, consumers are misled with the organic label,” says Härri.
