Capsaicin, the compound responsible for the characteristic heat of chili peppers, has been widely studied for its physical health benefits—such as its ability to relieve pain and speed up metabolism. However, more recent research is shedding light on a lesser-known aspect: its potential positive effect on mental health, particularly in disorders such as anxiety and depression.
What is capsaicin and how does it work in the body?
Capsaicin is a natural alkaloid that binds to TRPV1 receptors (transient receptor potential vanilloid-like 1 receptors), which are responsible for detecting heat and pain. When these receptors are activated, the body interprets a burning sensation, triggering a cascade of physiological and neurochemical responses.
One of these responses is the release of endorphins and dopamine , neurotransmitters associated with pleasure and pain relief. This chemical reaction may explain why many people experience a feeling of well-being or even euphoria after eating spicy foods.
Capsaicin and Mental Health: What the Science Says
Numerous preliminary animal studies and some human studies suggest that capsaicin may play a role in mood regulation. Some of the most relevant mechanisms include:
1. Release of endorphins and neurotransmitters
As mentioned, capsaicin stimulates the production of endorphins, known as the “happiness hormones.” It can also increase levels of dopamine and serotonin, key neurotransmitters in mood management and emotional well-being.
2. Reduction of inflammation
Chronic inflammation has been linked to depression and other mood disorders. Capsaicin has anti-inflammatory properties that may help reduce this systemic inflammation, thereby helping to alleviate depressive symptoms.
3. Stimulation of the gut-brain axis
The digestive system and the brain are closely connected. Capsaicin can improve gut microbiota, which in turn positively influences the production of neurotransmitters related to mental health.
4. Stress tolerance
Some studies suggest that capsaicin consumption may help increase stress tolerance and improve the body’s adaptive response to negative stimuli.
What do human studies say?
Although more research is still needed, some clinical trials have shown that people with diets rich in spicy foods report lower levels of depression and anxiety. A study published in Phytotherapy Research found that supplements containing capsaicin helped improve the mood of patients with mild to moderate symptoms of depression.
Precautions and recommendations
Despite its benefits, excessive consumption of capsaicin can cause gastric irritation or intestinal discomfort, especially in sensitive individuals. Furthermore, it should not be considered a substitute for traditional medical treatment for disorders such as anxiety or depression, but rather as a complement.
Tip: Incorporating spicy foods into your diet in moderation—such as natural chili sauces, chili-based stews, or supervised capsaicin supplements—can be a natural strategy to support emotional well-being.
Capsaicin, beyond adding flavor to our meals, may offer unexpected benefits for mental health. Through mechanisms such as the release of endorphins, reducing inflammation, and improving neurochemical balance, this spicy molecule is emerging as a potential ally in the fight against anxiety and depression. As always, it is essential to consult with a healthcare professional before making significant changes to your diet or treatment.
At Hugo Restrepo y Cía., we have been providing spicy ingredients containing capsaicin for 50 years.
