Rhodiola rosea is an adaptogenic plant that acts on several neurotransmitters to regulate brain activity and improve response to stress. Here's a detailed look at its effects on neurotransmitters:
---
1. Effects on dopamine
Inhibition of degradation: Rhodiola inhibits the enzyme monoamine oxidase (MAO), which degrades dopamine. This increases dopamine levels in the brain.
Increased motivation: Thanks to optimal dopamine levels, it promotes motivation, pleasure and productivity.
Reduced apathy: Helps combat mental fatigue and indifference, often associated with dopamine deficiency.
---
2. Effects on serotonin
Increased serotonin: Rhodiola works by increasing the availability of serotonin in the brain, which improves mood and reduces symptoms of depression.
Emotional stabilization: It helps balance emotions by modulating serotonin receptors.
Anxiety reduction: Serotonin, reinforced by Rhodiola, plays a key role in reducing stress and anxiety.

3. Effects on noradrenalin
Modulation of levels: Rhodiola acts on noradrenalin, improving alertness and attention while preventing excessive overstimulation.
Stress response: It regulates noradrenaline release for better adaptation to stress, reducing the effects of chronic stress.
---
4. Effects on GABA
Indirect regulation: Although Rhodiola does not act directly on GABA (an inhibitory neurotransmitter), its stress-reducing effect may promote better regulation of the nervous system, which relies on a balance between excitatory and inhibitory neurotransmitters.
---
5. Effects on acetylcholine
Improved memory: Rhodiola appears to enhance cholinergic transmission (linked to acetylcholine), improving memory, learning and mental clarity.
---
6. Effects on glutamate
Reduced excitotoxicity: Glutamate is an excitatory neurotransmitter, and by regulating stress levels, Rhodiola can prevent excess glutamate, which can damage neurons.
---
7. Neuroprotection
Reduces oxidative stress: Rhodiola protects neurons against damage caused by oxidative stress, helping to preserve neurotransmitters.
Prevention of imbalances: It promotes a balance between dopamine, serotonin, noradrenaline and other neurotransmitters for optimal mental health.

Conclusion:
Rhodiola rosea acts as a global regulator of the nervous system, balancing several neurotransmitters. It is particularly effective in reducing stress, improving mood, boosting concentration and protecting the brain against the damaging effects of chronic stress.
