Stress and histamine: Cortisol, adrenaline & noradrenaline in focus
Stress is a physiological reaction of our body to help us cope with stressful situations. Certain hormones in our body are of great importance and communicate with the brain via what is known as the stress axis.
The most important stress hormones include adrenaline, noradrenaline, and cortisol. These are released during acute and chronic stress and ensure that our body performs at its peak with all its functions.
These hormones influence your body, your mood, and your emotions. Hormonal imbalances can also lead to higher levels of stress hormones in your body. Would you like to learn more about the different stress hormones and their effects on the body? You can find all the important information in the following blog article.
The 3 most important stress hormones

Adrenaline as a kick-start hormone and noradrenaline as a focus hormone: General information
Adrenaline and noradrenaline are both released in the adrenal medulla and act immediately after a stressful situation. These two hormones ensure a rapid reaction within a very short time and lead to physical effects such as faster breathing and a faster heartbeat. They put the body into the classic "fight or flight" mode.

Cortisol: General information about the energy hormone
This hormone is produced in the adrenal cortex and reacts somewhat more slowly compared to adrenaline and noradrenaline. This hormone is released when the initially stressful situation is already subsiding but the stress continues. The cortisol level in the blood is generally highest in the morning hours and lowest at night.
The positive effects of cortisol include, among other things, that it can inhibit inflammation, sharpen attention, improve memory, and break down fat stores.
Chronic stress and increased cortisol levels: Health consequences
In the long term, an elevated cortisol level can also lead to consequences such as hormonal disorders, diabetes, bone loss, anxiety disorders, or depression.
Causes for this can be chronic stress, few breaks, life crises, or even relationship or family problems.
Lowering cortisol levels naturally: Here's how
With a few simple tips and tricks in everyday life, you can positively influence your cortisol level and thus lower it naturally. For example, by not drinking alcohol, drinking enough water, avoiding blue light in the evening, or ensuring sufficient sleep.
In general, it can be said that you can lower your cortisol level naturally by increasing your well-being. You can do this very individually. Breathing exercises, yoga, meditation, or walks can also positively influence your body in this regard.

The connection between emotions and hormones
From our brain, a wide variety of body functions are controlled and stimuli are processed.
A brief example: When you receive unexpected, alarming news that triggers a feeling of stress in you, this reaction is converted into biochemical signals and thus hormones are released.
When the stress is over, the hormone secretion also winds down, and your nervous system ensures that your organism relaxes and regenerates.
It becomes problematic when your hormonal system gets out of balance in the long term and a persistent hormonal imbalance exists. This can be caused by a wide variety of things such as medication, illnesses, pollutants, or even a nutrient deficiency.

Stress and digestion: How hormones affect your stomach
Adrenaline and cortisol can, for example, strongly influence the digestive system and have effects on the intestinal mucosa. This, in turn, then affects the stomach.
Especially when it comes to the intestinal mucosa, it is worth keeping an eye on your supply of important nutrients. Our MucosaFit combines selected nutrients and ingredients such as biotin, vitamin A, C, D and E, zinc, L-glutamine, fennel, and flaxseed. The biotin contained contributes to the maintenance of normal mucous membranes.
Nutrition and nutrients: How you can support your body in stressful situations
Here is how you can support your body in stressful situations:
- Water: It is important to drink enough water to flush out the substances that form in the body in stressful situations. In the case of histamine issues, this is also advantageous because histamine is water-soluble and can thus also be transported away.
- Vitamin D: A deficiency in vitamin D can influence your feeling of stress, as it is involved in many processes in the body such as cell growth or the maintenance of normal bones.
- Omega-3 fatty acids: An adequate intake of this fatty acid is essential because it contributes to normal brain function. Excellent sources are, for example, flaxseed, linseed oil, or chia seeds.
- Magnesium: In a stressful situation, the body releases more magnesium, so there is an increased demand. Therefore, mineral-rich foods such as green vegetables or nuts can be very helpful.
- Vitamin C: Vitamin C ensures, among other things, the normal function of the immune system. When the immune system is weakened, there is an increased risk of infection. An infection can lead to increased stress. Excellent sources of vitamin C are, for example, rose hips (1), sea buckthorn, and red bell peppers.
- B vitamins: These contribute, among other things, to the maintenance of a normal nervous system. You can find them, for example, in egg yolk, oatmeal, and yogurt.
- Proteins: These can support your muscles during and after a stressful situation. Since it is rather difficult to meet your protein requirements with a low-histamine or vegan diet, we can recommend the HistaFood Organic Protein Powder at this point. It contains 72 g / 100 g of plant-based protein. The product is suitable for a low-histamine and low-fructose diet, vegan, gluten-free, lactose-free, and made from 100% natural organic ingredients.
