Not every supplement is a sure-fire hit for the immune system. But there are clear signs that indicate whether a product delivers what it promises – or is just full of empty promises. We show you which criteria are important – and announce our test winner.
Your immune system is highly organised – it scans, reacts, protects and regulates, day after day. In order to perform these tasks reliably, it needs targeted support: micronutrients that act in the right places and support the immune network.
High-quality immune formulas deliver exactly that – sensibly combined, carefully processed and in an optimally bioavailable form.
Mother Nature is a true immune system expert. Traditional plant extracts bring a breath of fresh air to modern micronutrient formulas and provide added variety and naturalness.
These traditional plants have been valued for generations for their supportive role in the immune system:
Around 70% of our immune cells are located in the gut – and that's no coincidence, because this is where they are trained, regulated and balanced. So, if you support your gut in a targeted way, you are also doing your immune system a favour.
These components can provide valuable support in this regard:
Sometimes more really is more: Combination supplements that combine several immune-relevant nutrients can be particularly effective – especially if they complement each other and thus work together to boost your immune system.
However, if you have a specific deficiency, such as vitamin D or zinc, a targeted nutrient supply can be the key to restoring balance to your immune system.
There is more than just a good idea behind every high-quality supplement. For a proven effect, a solid scientific foundation is required – with active ingredients whose benefits, dosage and interaction have been thoroughly researched and confirmed by studies. This is the only way to create formulations that are based on evidence rather than trends – and thus truly deliver what they promise.
Premium manufacturers such as BIOGENA therefore rely on tested ingredients, research that demonstrates visible effects, and teams of experts who examine and refine every detail.
This is how knowledge translates into effectiveness and precision translates into trust.
True test winners are born out of dedication and mindfulness. Quality is not only evident in the capsule, but begins with the selection of pure raw materials, continues with careful processing and lives on in every detail of the manufacturing process.
How to recognise premium quality:
A true test winner impresses not only with its content, but also in everyday use – with high tolerability and ease of application.
High-quality immune supplements are gentle on the body, free from unnecessary additives and – where possible – vegan. They can be easily integrated into everyday life, whether as capsules, powder or drops – for an immune routine that simply fits.
Genuine quality is not only evident on paper, but also in everyday life – among the people who use a product regularly. Customer reviews and testimonials provide valuable insights into how well an immune supplement actually works and is tolerated.
After all, what good is the best theory if it doesn't work in practice? A true test winner for strengthening the immune system passes both tests – the scientific one and the everyday one.
BIOGENA Immun 24/7 is your daily companion for powerful defences – around the clock. The carefully considered formula combines 12 vitamins and 8 minerals that support the body, especially in times of increased stress.
Added to this are selected plant extracts from echinacea, rockrose, eucalyptus and astragalus, supplemented by beta-carotene, quercetin (Quercefit®) and beta-glucans – a powerful combination that harmoniously unites science and nature.
Junior Multi Bo® 13 contains colourful but uncoloured pellets (NutriGellets®) with 13 vitamins as well as iron and iodine – in child-friendly doses for an all-round balanced supply of micronutrients. This provides the body with important nutrients – including those that play a role in the immune system.
Thanks to the protective fish gelatine matrix, the small pearls are easy to take – on their own on a spoon, with water or sprinkled over a meal. For smart micronutrient power that children enjoy and parents trust.
BIOGENA SPORTS Immunity is our test winner for anyone who lives an active lifestyle and wants to give their immune system a targeted boost.
The sophisticated formula combines the best of science and nature: medicinal mushrooms such as reishi, cordyceps and shiitake are combined with plant extracts from turmeric, echinacea, black garlic, elderberry and black pepper – supplemented by the classic micronutrients vitamins A, C and D as well as zinc and selenium, which contribute to the normal functioning of the immune system.
The result: a powerful formula that supports you during active phases and reliably strengthens your immune system – for energy, balance and regeneration, even after training.
A strong immune system needs more than empty promises – it needs quality, knowledge and trust.
Our BIOGENA test winners demonstrate what modern micronutrient research can achieve: well-founded and carefully considered formulas, pure ingredients and maximum bioavailability – for noticeable support in every phase.
Omni Lactis® 20 Gold and Omni Lactis® 20 Pur Gold are our BIOGENA test winners when it comes to supporting the immune system. With 20 billion viable bacteria from 10 scientifically tested strains per daily dose, they support a diverse intestinal flora – and thus maintain your immune headquarters in a natural way.
