Stress and anxiety are natural responses to new or challenging situations, such as a divorce or moving house. However, when these feelings persist without any apparent cause, they can negatively affect the body and mind. The fight-or-flight response, triggered by a threat, releases hormones and neurotransmitters that prepare the body for action.
Prolonged hyperactivity can impair brain health and general well-being. Symptoms of anxiety include a rapid heartbeat, trembling, confusion and fatigue. To address these problems, natural supplements that may help manage stress and improve quality of life are recommended.
- GABA.
- Rhodiola rosea.
- Ashwagandha.
- L-Theanine.
- Tryptophan.
- Taurine.
- Stress Care.
1 GABA
GABA (gamma-aminobutyric acid) is a neurotransmitter that reduces overactivity in the brain and calms the nerves. This neurotransmitter has a relaxing effect, is involved in glutamate activation and reduces nervous tension.
According to clinical studies, GABA cannot cross the blood-brain barrier. However, increased GABA levels may help control anxiety or stress.
GABA contributes to:
- Reducing the body’s response to nervous tension.
- Inhibiting the transmission of nerve impulses in the brain.
- Achieving a sense of calm quickly and increasing serotonin levels.

2 Rhodiola rosea
Golden root (American Rhodiola rosea) is a plant that helps improve performance and has other effects, such as improving mood affected by nervous tension.
According to researchers, Rhodiola rosea improves mood, performance and attention and is therefore a natural alternative, better than medication, for relieving tension and depression. Rhodiola works by normalising the body’s natural response to stressors.
Rhodiola rosea may help to:
- Reduce tension, fatigue and irritability.
- Treat chronic anxiety disorders.
- Normalise the response to stressors.

4 L-Theanine
L-Theanine is an amino acid found in green tea that has calming and relaxing effects. L-Theanine is one of the most popular remedies for anxiety. It helps improve concentration while also helping to calm nervousness.
L-Theanine increases the release of the neurotransmitter GABA and reduces nervous stimulation in the brain.
According to researchers, L-Theanine lowers the heart rate and also inhibits the release of adrenaline by the sympathetic nervous system and the increase in heart rate typically associated with anxiety problems.
L-Theanine helps to:
- Improve concentration.
- Increase serotonin levels.
- Produce alpha waves in the brain, which are associated with relaxation and concentration.

5 Tryptophan
Tryptophan is an essential amino acid that acts as a precursor of the neurotransmitters serotonin and melatonin, which have calming effects and improve mood and sleep.
Tryptophan contributes to:
- Reducing anxiety and stress.
- Increasing serotonin levels, helping to combat depression.
- Promoting melatonin production and regulating sleep cycles.
- Supporting mental clarity and memory.

6 Taurine
Taurine is an essential amino acid that plays an important role in several biological functions, particularly in the regulation of the nervous system. Known for its relaxing and antioxidant properties, taurine is an effective supplement for combating stress and improving both mental and physical health.
Taurine contributes to:
- Mitigating the effects of chronic stress by regulating the nervous system.
- Stabilising mood by interacting with neurotransmitters in the brain.
- Protecting the heart and improving blood circulation.
