Don't give viruses a chance!

⏱ 9 min read

What about your health?

Did you already have a cold or do you have one now?

Every year between December and January, the cold and flu season begins and lasts for up to 4 months.

Recent studies show that young people in particular are catching the flu disproportionately often. Children and young people between the ages of 10 and 19 and young adults up to the age of 25 are particularly affected.

But younger children and older or already weakened people are also particularly at risk from viruses and bacteria.

➤ Adults suffer from colds 3-4 times a year, children up to 10 times!

How is it that flu viruses surprise so many of us every year?

There are several reasons for this:

1. Viruses love the cold weather. Cold and dry air provide the ideal living conditions for viruses.
2. Our mucous membranes are highly irritated by the constantly heated air. Mucous membranes normally offer good protection against viruses and bacteria, but the dry, warm air puts a lot of strain on them. The result: the body's own barrier is weakened.
3. Viruses are survival artists. They are constantly changing and adapting, making it difficult for our immune system to immediately recognize them as such. They are also very persistent and survive on the palms of our hands, door handles and even banknotes.
   
   

➤ Young and older people are particularly susceptible to flu viruses!

So what can we do to combat annoying viruses and bacteria and strengthen our immune system in the long term?

The quick help for colds:

1) Zinc - the immune booster

Zinc is particularly known for its antiviral effect. In combination with vitamin C, zinc helps to strengthen the immune cells. Studies show that zinc reduces the severity of cold symptoms by around 40 % and shortens the duration of an illness by 3-4 days!

2) The classic - vitamin C

We all know that vitamin C strengthens our immune system. Study results show that taking 5,000 mg of vitamin C per day reduces the illness phase of a cold from an average of 9 days to 5 days or less.

3) Vitamin D - the sunshine vitamin

Almost half of us are affected by a vitamin D deficiency, especially in winter. This deficiency inevitably leads to a weakened immune system. And not only that, our mood also drops at the same time as our vitamin D levels.

What to do at the first signs of a cold

A scratchy throat, the first sneeze, a heavy head: the first 24 hours are the best moment to act. These four steps make the difference:

• Start with zinc straight away: In a pooled analysis of three randomized, placebo-controlled trials with 199 cold patients, those who took zinc lozenges recovered three times faster. On the fifth day, 70% of the zinc group had recovered, compared with 27% of the placebo group. The researchers advise starting within 24 hours of the first symptoms (Hemilä et al., 2017). A second meta-analysis of seven randomized trials with 575 participants found that colds were on average 33% shorter with zinc. Four of these trials used zinc gluconate (Hemilä, 2017).
• Top up your vitamin C: A meta-analysis of ten randomized, double-blind trials found that vitamin C in doses of at least 1 g a day made colds 15% less severe. The benefit showed above all in the severe symptoms (Hemilä & Chalker, 2023).
• Go to bed early: In a study, 164 healthy adults were given a cold virus as nasal drops. Those who had slept less than six hours a night in the week before had more than four times the odds of developing a cold compared with those who slept more than seven hours (Prather et al., 2015).
• Drink plenty: Water and unsweetened herbal tea keep your mucous membranes moist, and moist mucous membranes are your body's own barrier against viruses.

The Immune Power Package brings the three quick helpers from this guide together in one set: Zinc Super Plus with zinc gluconate and vitamin C, natural vitamin C from the acerola cherry and vitamin D3 drops.

Treating a cold or flu is one thing. However, it is more important to prevent illness at an early stage. 

But what is the best way to arm yourself against viruses and bacteria?

Actively prevent viruses and bacteria now!

1. soak up the sun - whenever possible

Sure, it's difficult to get enough sun in winter as it gets dark early and the weather is often bad. But make the most of all the sunshine you can get. How about going on vacation in winter and spending it somewhere sunny? This also makes the cold and dark months more bearable.

2. exercise regularly

You don't have to do extreme sports to stay healthy. Just 30 minutes of light exercise a day will help you. Exercise strengthens your antibodies and white blood cells, which are largely responsible for your immune system.

3. reduce your stress

Take time for relaxing activities such as listening to music or meditating. This is because stress releases the hormones cortisol and adrenaline, which put a strain on your immune system. A weakened immune system is more susceptible to colds and viral infections.

4. drink enough

Especially in winter, when the heating is on full blast, our mucous membranes dry out quickly. This makes us all the more susceptible to viruses and bacteria. Adequate hydration increases your cold-fighting potential. 

5. recover while you sleep

If you sleep too little, it affects your immune system. According to a sleep study, sleep deprivation has a significant detrimental effect on the immune system after just a few days. Adults should sleep between 7 and 9 hours a night. People who are already ill should sleep even more.

6. eat a balanced and healthy diet

A healthy diet is extremely important for general well-being. In most cases, a combination of certain foods is ideal for defending against bacteria, viruses, etc. These include garlic, ginger, spinach, pulses, omega 3 fatty acids (EPA and DHA) and foods with high levels of zinc (chickpeas), selenium (broccoli & barley), vitamin C (red peppers & citrus fruits) and vitamin E (nuts & seeds). 

7. supplement your diet with the power of nature

To further strengthen and maintain your immune system naturally, it's important to create healthy habits for overall wellness. One of the best ways to boost your immunity during cold and flu season is to use high-quality vitamins, minerals and nutrients. Developing a supplement routine is nutritional insurance for winter wellness.

Which nutrients help prevent colds? What large studies show

Four nutrients have been tested for the prevention of colds and other respiratory infections in large analyses of randomized trials:

• Vitamin D: In an analysis of 25 randomized, placebo-controlled trials with 11,321 participants aged 0 to 95, vitamin D protected against acute respiratory infections. The protection was clearest with daily or weekly intake and strongest in people who started with a marked vitamin D deficiency (Martineau et al., 2017).
• Vitamin C: In five trials with 598 marathon runners, skiers and soldiers, regular vitamin C halved the risk of catching a cold. Taken regularly, vitamin C also shortened colds by 8% in adults and by 14% in children. In children, 1 to 2 g a day shortened colds by 18% (Hemilä & Chalker, 2013).
• Zinc: In 28 randomized trials with 5,446 adults, zinc taken by mouth or as a nasal spray prevented 5 respiratory infections per 100 person-months compared with placebo (Hunter et al., 2021).
• Probiotics: Across 23 trials with 6,950 children, adults and older people, probiotics were better than placebo at preventing acute upper respiratory tract infections. When an infection did occur, it was on average 1.22 days shorter (Zhao et al., 2022).

Zinc, vitamin C and vitamin D3 are exactly the three nutrients in the Immune Power Package, so you can cover all three with one set throughout the cold season.

Build up your immune system sustainably with:

1) Vitamin booster for your health

The vital substance concentrate contains only the best of high-quality fruit, vegetable and berry concentrates as well as herbal and plant extracts. You receive 35 daily portions with the most important vitamins and minerals for your immune system!

2) Probiotics - intestinal power from within

A study conducted in 2009 with schoolchildren reported that fever, cough and runny nose were reduced after 3 months of taking probiotics. The number of sick days was almost halved and the use of antibiotics was reduced by over 80 %.

3) The power of medicinal mushrooms

Whether reishi, cordyceps or shiitake - medicinal mushrooms are great immunity boosters! The beta-glucans they contain help the body to strengthen the immune system against infections.

Conclusion:

Our immune system basically has a good defense system. However, this natural defense needs external support from time to time when it comes to coping with colds or a flu epidemic.

➤ Our final tip: Don't forget to wash your hands frequently with soap! This will already reduce your risk of infection!

Frequently asked questions

How to stop a cold when you feel it coming on naturally?

Act within the first 24 hours: start with zinc, top up your vitamin C, drink plenty and go to bed early. In a pooled analysis of three randomized trials, 70% of the cold patients who took zinc lozenges had recovered by the fifth day, compared with 27% in the placebo group (Hemilä et al., 2017).

Can vitamin C really shorten a cold?

Yes. A review of 31 trial comparisons found shorter colds with regular vitamin C: by 8% in adults and by 14% in children (Hemilä & Chalker, 2013). In a second meta-analysis, vitamin C in doses of at least 1 g a day also made colds 15% less severe (Hemilä & Chalker, 2023).

Does zinc help stop a cold?

Yes. In a meta-analysis of seven randomized, placebo-controlled trials with 575 participants, colds were on average 33% shorter with zinc (Hemilä, 2017). Researchers advise starting with zinc within 24 hours of the first symptoms (Hemilä et al., 2017).

How does the body get rid of a cold virus?

Your immune system does the work. Its cells release messenger substances called cytokines, and these explain typical cold and flu symptoms such as fever, chilliness, headache and muscle aches (Eccles, 2005). You support this work with enough sleep, plenty of fluids and nutrients such as zinc, vitamin C and vitamin D.

How to prevent spreading a cold virus?

Wash your hands often with soap, because cold viruses survive on the palms of the hands, on door handles and even on banknotes. In nine trials with 52,105 participants, hand hygiene lowered the number of people with acute respiratory infections by 14% (Jefferson et al., 2023).
