Advertorial: The immune system and triathlon sport

Vitamins and minerals are essential for thousands of biochemical reactions and functions in our body. The perfect balance of vitamins and minerals is crucial for a well-functioning nervous system and a fundamental building block for a strong immune system.


In our daily lives, we are surrounded by stress and pressure to perform. Therefore, it is important to support a healthy lifestyle with wholesome and healthy foods and with certain minerals or vitamins that are essential for a healthy immune system. These are the very ingredients that AG1 is very rich in.


Your immune system is also extremely complex. It is made up of many biological structures and processes that together form a formidable defence against viruses, parasites, infection-causing bacteria and other pathogens.

When it is in top form, it recognises threats and destroys them. Not only that, it remembers these threats and knows exactly what to do the next time they appear.


How to support your immune system where it matters most


As we know, gut health is crucial for a well-functioning immune system. A healthy and balanced diet should therefore be a top priority for us. If your diet is not optimal, you cannot expect your immune system to function optimally.


Despite a balanced diet, certain nutrient deficiencies can occur.

These deficiencies can change over time, especially if our diet and food sources change.


Especially in competitive sports, it is important to ensure that such nutrient gaps are avoided as much as possible. Intense training and participation in competitions can take their toll and make the body more susceptible to possible infections.


The Open Window Effect


After intense physical exertion, the body is particularly susceptible to infections. The reason for this is that during exercise the number of white blood cells (lymphocytes), which form part of the immune defence system, increases. After the end of exercise, this number drops again, below the initial level.

Vitamin D in combination with zinc manages to bring the level of white blood cells back to the level they were at before exercise. It is therefore advisable to take vitamin D and an additional portion of AG1 (which contains zinc as well as many other ingredients important for the immune system) directly after the intensive training session or competition.


This is therefore the period in which the immune system becomes particularly susceptible to pathogens. The duration of the "open window" can be between 3 and 72 hours.

Particularly in cool temperatures, the mucous membranes of the upper respiratory tract are also heavily stressed and pathogens and viruses have an easier time triggering a flu-like infection.


This is where a high-quality and wholesome supplement with high bioavailability can make a difference. Let's find out how.




The vitamins, minerals and trace elements (zinc, selenium) contained in AG1 can support the immune system.

Selenium and vitamin D contribute to normal immune system function.

Manganese contributes to the normal formation of connective tissue.

They all work together in the body to support a healthy immune system.


AG1 provides everything you need to ensure every cell is hydrated. It provides you with the necessary amounts of sodium, potassium and magnesium, as well as various botanicals that naturally provide additional bioavailable minerals to support electrolyte and mineral balance.


The 4 essential micronutrients for the immune system

While our body's need for vitamins and minerals is extremely complicated, there are a few specific micronutrients that have been shown to be particularly beneficial for the immune system:

essential micronutrient

main benefit

contained in

Vitamin A

It supports the maintenance of a normal immune system.

Oranges, beetroot, peppers

Vitamin C

Vitamin C helps maintain normal immune system function during and after intense physical activity and protects cells from oxidative stress.

Kiwi, Indian gooseberries, citrus fruits

Vitamin E

Protects the cells from oxidative stress.

Almonds, spinach, sweet potato, avocado


Contributes to normal immune system function and protects cells from oxidative stress. It plays a role in cell division and contributes to a normal acid-base balance.

Oysters, beef, cashew nuts, spinach, chickpeas, oats

Most of us most likely do not count some of these nutrient sources among our daily nutrient sources. So how do we ensure that our bodies are still getting all the necessary vitamins, minerals and micronutrients that can support a healthy immune system on a daily basis? This is where a vitamin complex can come in and be beneficial.


But: most multivitamin supplements (especially those you can get for a few bucks at the drugstore) contain synthetic, hard-to-absorb versions of the vitamins and minerals you need.


To compensate for the inferior quality of the ingredients, the dosage can be increased, which in turn increases the risk of toxicity, especially with fat-soluble vitamins like A and D and minerals like zinc and selenium.


In addition, commercially available multivitamin supplements usually do not contain live cultures that support gut health and thus immune function.
