    New in vitro co-culture model study published with citrus flavonoid extract MicrobiomeX®

    Maastricht, Netherlands, April 21st, 2022

    Press release
    British Journal of Nutrition has recently published a new in vitro co-culture model study with a citrus flavonoid extract MicrobiomeX® and its metabolites, hesperetin and naringenin. The novel publication suggests that these citrus flavonoids, as well as their metabolites, may reduce intestinal inflammation.

    New in vitro co-culture model study published with citrus flavonoid extract MicrobiomeX®

    MicrobiomeX® is a first-in-class Flavobiotic® developed by BioActor, that combines active ingredients from Citrus sinensis and Citrus paradisi. MicrobiomeX® has already been studied and reported to have various beneficial effects on the gut and immunity. MicrobiomeX® consists of standardised citrus flavonoids, that form active metabolites, hesperetin and naringenin, in the gut after being deglycosylated by the gut microbiota.

    In the recently published in-vitro study, a validated co-culture system of Caco-2/THP-1 cells as model for intestinal inflammation and cytokine-induced barrier disruption was used to determine the effects of citrus flavonoids and their metabolites on intestinal inflammation.

    During the research, cells were treated with citrus flavonoids, their metabolites, or a vehicle control. Additionally, cells were incubated with lipopolysaccharide (LPS), which is known to induce inflammation and deterioration in epithelial integrity.

    The conclusion highlights that hesperetin and naringenin significantly reduced NF-kB activity, leading to a reduction in intestinal inflammation. Pro-inflammatory cytokines IL-8, TNF-α and IL-6 were also significantly reduced after hesperetin and naringenin administration.

    The mechanism behind this reduction in inflammation can be ascribed to partial inhibition of the NF-κB signalling pathway.

    “We are very happy with the results of this study, as we were able to show that both the citrus flavonoids themselves and their metabolites are able to reduce inflammation in the intestine”, says Yala Stevens, CSO of BioActor. “These new scientific insights on MicrobiomeX® will allow us to consolidate its applications to products targeting gut health and immune function”.

    What-are-the-best-substitutes-for-caffeine?

    What are the best substitutes for caffeine?

    What are the best substitutes for caffeine?

    April 21st, 2022

    A wide variety of caffeine-containing products are available, ranging from coffee and tea to dietary supplements, sodas and energy drinks. However, consuming too much caffeine often leads to side effects such as stress, anxiety, and even sleeping problems. If you are looking for alternative products to boost energy levels and increase focus, Brainberry®, maca root, ginseng, Rhodiola, and Lion’s Mane are natural ingredients that can help you get through the day without side effects.

    What-are-the-best-substitutes-for-caffeine?

    Why should you substitute caffeine with another ingredient?

    Most people drink coffee regularly. It is consumed because people like the taste or because of the social aspects to drinking coffee, but the most important reason people consume coffee is that it makes them feel more awake, alert, and energetic.

    Of course, coffee is a source of caffeine, which is the ingredient that gives coffee its effects. There are other drinks that contain caffeine, and some people even take dietary supplements containing caffeine to boost their energy levels during the day or for their workout. [1].

    Besides positive effects, consumption of caffeine may also have some downsides. These include giving people feelings of stress and anxiety. Besides increasing these feelings, caffeine consumption could also lead to insomnia [2].

    Caffeine is unique in its function, but these adverse effects are a reason for people to reduce the intake of caffeine and look for alternative ingredients. Here are some suggestions of natural substitutes that make you feel awake and help you focus, without leaving you feeling stressed.

    The best substitutes for caffeine

    1. Maca root

    Maca is a plant that grows in Peru (also called Peruvian ginseng). It’s a plant that belongs to the brassica (mustard) family. It is traditionally used for nutritional and medicinal purposes. The plant is made into a powder that is often added to smoothies, juices, and shakes.

    It has been used for centuries as a fertility enhancer in humans and animals, but now more benefits of consuming maca are being discovered. The benefits of maca root vary, and evidence shows it may help increase energy levels and improve mood.

    Additionally, other findings show that maca can help against feelings of anxiety and stress. This makes Maca a good alternative to caffeine, which can have the opposite effect.

     

    2. Ginseng

    Like maca, ginseng is a herb made from the root of its plant. It has been one of the most important products for health care in Asia. There, it has been used to make traditional medicine for centuries.

    There are different types of ginseng, which vary in the way they are grown and processed. White ginseng is dried naturally, while red ginseng is steamed before it is dried, which increases its efficacy. The most important compounds in ginseng are ginsenosides and gintonin [3].

    Ginseng is one of the most popular caffeine substitutes. Various research demonstrated that this plant is able to improve brain functions, boost mood and memory, help against fatigue, and increase energy levels.

     

    3. Brainberry® (Aronia berry extract)

    Aronia berries are becoming increasingly popular among consumers because of their many demonstrated health benefits. Aronia plants are native to North America but are also commonly found in the Baltic region of Europe.

    Brainberry® is an Aronia berry extract researched and developed by BioActor. It was demonstrated that the daily consumption of Brainberry® is able to boost mental energy and focus without side effects. An ideal alternative if you want to get rid of caffeine!

    The main constituent of Brainberry is an anthocyanin called Cyanidin 3-O-galactoside, a powerful antioxidant that can improve brain health and support brain function.

     

    4. Rhodiola

    Rhodiola is a plant that can be found in Europe and Asia. Like ginseng and maca its root is consumed for health benefits. Rosavin and salidroside are believed to be its most profitable compounds.

    Rhodiola has been used for many years and has been mostly recommended to treat headaches, hernias and has also been used as an astringent. Nowadays, rhodiola is often consumed by people during stressful times.

    If you’re looking for a natural alternative to caffeine that reduces fatigue, rhodiola is a good option because it has been shown to improve symptoms in participants that suffered from chronic fatigue. The stress-lowering and energizing effects of rhodiola make it a great natural replacement for coffee.

     

    5. Lion’s Mane

    Lion’s Mane is a mushroom that can grow long hair-like strings that resemble a lion’s mane. It is often found in North America, Europe, and Asia. It consists for roughly 20% out of protein.

    Lion’s Mane is increasingly studied. It has properties that are believed to be neuroprotective. That is because two novel nerve growth factors have been discovered in this mushroom [4].

    Lion’s Mane has thus been said to have positive effects on the brain. It can improve memory and helps to lower feelings of stress and anxiety. This makes it an ingredient that can help consumers cut down on their caffeine consumption.

    The bottom line

    We all love a good cup of coffee in the morning. However, there are several reasons to reduce caffeine intake and look for a substitute. The aforementioned ingredients are good natural alternatives to caffeine as they can boost energy levels and brain functions, without having any anxiety or stress inducing effects.

    How to increase endurance performance during sport

    How to increase endurance performance during sport

    April 14th, 2022

    Do you experience an overall lack of energy during sports activities? Then it’s time to increase your endurance performance during physical activity. In this article, we will explain what endurance is, why is important for you and which nutrients and supplements can support your diet, boost your energy levels, help you recover faster, and enhance your overall performance during your training.

    How-to-increase-endurance-performance-during-sport

    Endurance Performance in different sports

    Endurance is the ability to sustain an activity for extended periods of time and usually relates to aerobic or anaerobic exercise [1].

    Aerobic endurance applies to sports like long-distance running or swimming where athletes exercise for extended periods of time. In this type of exercise, the body relies on supplying nutrients and oxygen to working muscles.

    On the other hand, anaerobic endurance is related to high-intensity exercises that may last minutes such as weightlifting. In these cases, a different type of endurance (strength) is necessary to achieve the maximum number of sets and reps in a workout plan.

    Nowadays, many athletes also focus on activities that include resistance with the body (calisthenics) or equipment such as weight machines and barbell exercises. In these cases, a different type of endurance (strength) is necessary to achieve the maximum number of sets and reps in a workout plan.

    The conclusion in each case is that high volume of training puts extreme demands on the body from a physical (strength & power), mental (focus) and energy (endurance) retention standpoint.

    Why is endurance performance important?

    Endurance can benefit your overall wellness by improving heart health, lowering the levels of cholesterol and blood pressure, preventing injuries and controlling your weight.

    As it concerns your performance skills, studies have shown that endurance helps athletes develop skills like agility, speed, power, and strength. More specifically, it is an efficient way of maintaining your energy levels before fatigue sets in.

    As an example, you can consider a basketball player who wants to jump for rebounds in the final minutes of an intense game or even a marathon athlete that needs to run the last kilometers of a demanding race.

    Thus, endurance can keep your circulatory system healthy and make the difference between winning or losing in different sports.

    Ways to boost your endurance during sport

    As Paul Krebs, MD, of Premier Orthopedics, part of Premier Physician Network asserted, “body has the ability to get oxygen to the body and to the muscles that are using it during exercise.” A workout program focused on endurance training can lower the level of work-related fatigue [2]. The American Heart Association (AHA) recommends all adults get 150 minutes of aerobic exercise each week.

    However, nutrition is also an essential factor that influences the endurance of athletes. More specifically, it has been proved that nutritional supplements in performance endurance and enhancement are essential for athletes, even though there is a lack of knowledge of their use. Thus, athletes need reliable information regarding supplements they can trust and use in their daily demanding life [3]. In the next section, we will focus on the ingredients that a supplement should include for increasing endurance performance.

    Ingredients for endurance

    L-Glutamine

    Even if the body can synthesize glutamine, its levels might not be sufficient for athletes. The body can become depleted of glutamine in case of high intensity training [4] and as a result, athletes seek to increase the dosage intake by supplementation.

    L-Glutamine accelerates muscle recovery while it helps athletes to exercise harder. The increased sodium uptake reduces muscle fatigue and breakdown while maintaining muscle growth.

    The recommended dosage for L-Glutamine is between 3 to 6 grams [5].

    Carbohydrates

    As it was mentioned previously, athletes need endurance for different types of training. For example, marathon runners exercise for extended periods of time and require a lot of carbohydrates to sustain their performance.

    Any athlete who exercises for more than 60 to 90 minutes requires carbohydrate intake during their performance to sustain sufficient energy levels for fueling muscles since their glycogen stores may only last a limited time.

    A combination of carbohydrates with a small amount of protein has been shown to efficiently prevent the amount of muscle damage that occurs during an endurance exercise [6].

    The daily recommended dosage for Carbohydrates depends on the type of exercise. The American College of Sports Medicine (ACSM), the Academy of Nutrition and Dietetics (AND), and Dietitians of Canada (DC) recommend:

    • Moderate endurance exercise (1 hour per day): 5-7 g/kg of body weight per day.

    • Moderate to high-intensity endurance exercise (1-3 hours per day): 6-10 g/kg of body weight per day.

    • Moderate to high-intensity endurance exercise (4-5 hours per day). 10-12 g/kg of body weight per day.

    Caffeine

    Caffeine is a stimulant that athletes can use to temporarily boost their energy [8]. More specifically, it can increase the heart rates when athletes feel fatigued, and it has been proven to improve endurance performance [6].

    Even if caffeine reduces athletes’ perception of effort, it is important to be aware of the side effects it might have in higher intakes [9]. Some of the side effects of too much caffeine are anxiety, insomnia, muscle breakdown, rapid heart rate and high blood pressure.

    It is also possible that caffeine has the opposite result where the consumption of many caffeinated beverages is followed by fatigue [10].

    The recommended clinical dose of caffeine is between 3 and 6 mg/kg.

    Citrus flavonoids (hesperidin) – Power and endurance in one ingredient

    If you want to increase your endurance, strength, and power during a high intense training, you should bear in mind an extra ingredient with the name of citrus flavonoids (hesperidin). BioActor has developed a proprietary ingredient that is optimized for bioavailability and performance, backed up by two clinical studies: WATTS’UP®.

    WATTS’UP® was studied for its beneficial effects on endurance performance and high-intensity performance at a daily dose of 400-500 mg.

    The first clinical trial was conducted at the Dutch Olympic training facility. It confirmed that WATTS’UP® is capable of significantly improving aerobic power in endurance athletes in comparison to placebo.

    A second clinical trial was tested during the Wingate Anaerobic Test. It confirmed that WATTS’UP® can be very efficient for Peak Force, Anaerobic Power, and Endurance compared to placebo.

    In conclusion, proper nutrition in addition to a well-designed training plan, can enhance sporting performance and reduce recovery time.


    TIM-2 in-vitro-gastrointestinal-model

    What is the TIM-2 system? An in-vitro model of the colon

    What is the TIM-2 system? An in-vitro model of the colon

    April 8th, 2022

    The TIM-2 model is a dynamic gastrointestinal model, which is used for in-vitro research. The TIM-2 model can be used to study changes in the microbiota composition and the production of beneficial molecules in the gut. It resembles the human large intestine, including peristalsis, dialysis, and microorganisms. It is a good model that provides short experiment durations and the studies done with it are highly reproducible.

    TIM-2 in-vitro-gastrointestinal-model

    What is the TIM-2 model?

    The TIM-2 (TNO in-vitro) model is a computer-controlled dynamic in-vitro gastrointestinal model of the colon used in research to study changes in the microbiota composition.

    This model closely mimics part of the human large intestine, including its microorganisms, peristaltic movements, temperature (37ºC) and acidic pH (5.8).

    What is the TIM-2 model used for in research?

    The TIM-2 model has a wide range of applications in research. It can be used to study changes in the microbiota composition and production of beneficial molecules such as short-chain fatty acids associated with specific dietary patterns or ingredients and, consequently, to increase human health through the understanding of microbiota.

    Due to the health benefits of short-chain fatty acids (SCFA), many studies have focused on carbohydrate fermentation and the subsequent production of SCFA.

    However, it has also been used to study the effects of probiotics after antibiotic treatment, fermentation of prebiotic fibres, metabolization of molecules such as flavonoids and even to investigate the differences in microbiota from lean and obese individuals.

    Watch the interview with prof. Koen Venema

    Difference between TIM-2 model and other in-vitro models

    Compared to other in-vitro models, TIM-2 holds some unique features, which allow predicting what would happen in an actual clinical trial.

    The way the peristaltic movements are produced in the TIM-2 model gives a better mixing of the components than what would be accomplished by stirring or shaking. Thanks to this, in TIM-2 there is no phase-separation of solids and liquids, which is what occurs in other models.

    On the other hand, in vivo microbial metabolites are normally taken up by the gut epithelium. This is, of course, not possible in an in-vitro model, but the TIM-2 model features a unique dialysis system that removes these metabolites produced by microorganisms.

    The accumulation of these microbial metabolites would otherwise result in the inhibition or death of the microorganisms present in the model. Therefore, the dialysis system allows maintaining a highly active microbiota, with a similar density to that found in the human intestine.

    In other systems, metabolites tend to accumulate. In fact, with the TIM-2 model, since all the microbial metabolites are collected, they can be measured, which is something not possible in a real-life setting.

    What are the advantages and limitations of the TIM-2 model?

    Advantages of the TIM-2 model include:

    Short experiment duration. Compared to other models, experiments are quick, usually taking three test days or even less.

    Presence of peristaltic movements and dialysis system. These two unique features allow predicting what would happen in an actual clinical trial.

    Single parameter study. If a single parameter in the system is changed, the effect of that parameter on the microbiota can be studied.

    Highly reproducible. Since the model is computer-controlled, it is highly reproducible.

    Like other in-vitro models, the TIM-2 model has some limitations, which include:

    Absence of gut epithelial cells, immune cells and neurons. However, samples can be taken and incubated with these kinds of cells to investigate interactions.

    Based mostly on healthy individuals. The model has been developed based on data coming from mostly healthy individuals. For this reason, it is unclear exactly which parameters to adjust when simulating patient populations.

    Absence of feedback mechanisms. Due to this, as with similar in-vitro models, the results will always be an indication of what may occur in real life and, therefore, they should be interpreted carefully.


    BDNF: A key molecule for cognition and eye health

    BDNF: A key molecule for cognition and eye health

    April 1st, 2022

    Brain-derived neurotrophic factor (BDNF) is a protein highly expressed in the central nervous system, especially in the brain. BDNF promotes the growth of dendrites and dendritic spines, contributing to synaptic strength and plasticity in the hippocampus, thus important for learning and long-term memory. Research shows that increased levels of BDNF in serum are correlated with improved cognitive functions while decrease in BDNF is associated with neurodegenerative and mental illnesses. Moreover, new scientific evidence suggests that BDNF is also an important factor in eye health.

    What is BDNF and why is it so important?

    BDNF belongs to the neurotrophin family of growth factors and plays an important role in brain development, mainly growth and maturation of neurons and synapses.

    Highest levels of BDNF can be found in hippocampus, amygdala, cerebellum and cerebral cortex in both rodents and humans [1]. As well as in the brain, BDNF has been detected in other tissues such as the eye, lung, liver and skeletal muscle.

    Today we know that BDNF is also crucial for the adult brain, where it regulates synaptic changes and efficacy.

    BDNF is believed to be involved in the cellular mechanisms underlying memory formation and consolidation, learning and other complex behaviors by promoting long term potentiation in hippocampus [2].

    BDNF in disease and the ageing brain

    BDNF also seems to play a significant role in brain damage repair. Studies have shown that following traumatic brain injury, the mRNA expression level of BDNF is temporarily significantly upregulated in the injured cortex and in the hippocampus. These findings suggest that BDNF acts as an endogenous neuroprotective mechanism attenuating cell damage [3].

    In addition, emerging scientific data suggest that BDNF could be involved in the pathophysiology of brain-associated diseases. Impaired BDNF signaling has been observed in several diseases, such as Huntington’s disease, Alzheimer’s disease, depression, schizophrenia, and bipolar and anxiety disorders.

    Finally, part of the natural process of ageing is reduction of hippocampal volume and decrease in BDNF expression, which is associated with age-related cognitive decline [4].

    What is the role of BDNF in eye health?

    BDNF is produced by neurons and glial cells in the retina. Similarly to the brain, research indicates that BDNF could be involved in retinal development by modifying neuronal cell number or synapse formation [5].

    Nowadays, our eyes are constantly being overworked as a consequence of increased usage of visual display terminal (VDT) devices, such as smartphones, computers or tablets. This can negatively affect blink frequency, which can induce dry eye and associated symptoms including pain, burning and visual disturbances.

    Interestingly, BDNF knockdown mice showed decreased basal tear secretion, pointing at the role of BDNF in tear secretion and to the pathology of dry eye disease [6].

    Moreover, recent studies show that BDNF plays a vital role in other eye diseases, such as age-related macular degeneration (AMD) or diabetic retinopathy (DR). In AMD patients, serum BDNF levels are decreased and the same trend is observed in DR patients.

    These findings suggest that optimal BDNF levels may be necessary to exert protective effects on the eye and that decreased levels of BDNF signal eye disease [7, 8].

    How can you increase BDNF naturally?

    Control your stress levels
    Acute stress down-regulates hippocampal BDNF mRNA expression and interestingly, antidepressants up-regulate BDNF expression [9]. Practicing yoga or other stress management techniques therefore seem to be an efficient way how to boost your BDNF [10].

    Exercise
    Some studies have shown that exercise enhances the expression of BDNF. The reasoning is not fully understood but one possible explanation is that exercise leads to the release of the ketone body β-hydroxybutyrate, which in turn induces the activity of BDNF promoters [11].

    Practice occasional fasting
    Not every stress is bad for your brain: it appears that mild metabolic stress associated with dietary restriction leads to significantly enhanced expression of various neurotrophic factors, BDNF included. A study showed that following 48-hour fasting, BDNF was significantly upregulated in human skeletal muscle [12].

    Eat anthocyanin rich foods
    Apart from the above mentioned, dietary interventions have been also gaining on attention as a potential strategy to elevate BDNF levels. There is extensive scientific evidence that foods high in anthocyanins, such as edible berries, are good for your brain health [13]. A recent study showed that 6-week supplementation of pure anthocyanins increased BDNF expression and improved spatial and psychomotor performances in aged rats [14].

    Aronia melanocarpa anthocyanins and BDNF

    Aronia melanocarpa is a berry native to North America, which is higher in anthocyanins than any other berries. Aronia-specific anthocyanin, cyanidin-3-O-galactoside (Cy3Gal), crosses the blood brain barrier and interacts with BDNF sinaling pathway, thereby contributing to a better neuronal signalling.

    In a double-blind placebo-controlled crossover study, we recently demonstrated that short-term supplementation of Brainberry®, aronia melanocarpa extract with a standardized content of Cy3Gal, significantly increased BDNF levels in healthy young adults.

    The bottom line

    Given all the scientific evidence, BDNF plays a huge role in brain fitness, brain disease and eye health.

    Manipulating BDNF levels through dietary factors might be a promising strategy to not only treat various neurological and psychiatric disorders, but also to naturally boost memory and learning.

    To level-up BDNF is desirable for everyone: not only for the ageing population but also for young professionals seeking ways to enhance their cognition.
