The Sweet Science: Unpacking What Hormone Does Chocolate Raise?

2 min read

Research has shown that consuming dark chocolate can significantly reduce levels of the stress hormone cortisol. This raises the question for many health-conscious individuals: what hormone does chocolate raise and what other chemical messengers does it influence to produce its renowned mood-lifting effects?.

Quick Summary

Chocolate consumption triggers the release of several key neurochemicals, including mood-enhancing endorphins, reward-related dopamine, and relaxing serotonin. Phenylethylamine and other compounds in cocoa contribute to these feelings of pleasure and well-being.

Key Points

Multiple Neurotransmitters: Chocolate consumption, particularly dark chocolate, influences a range of neurochemicals, including endorphins, dopamine, and serotonin, not just a single hormone.
Phenylethylamine (PEA): A compound in cocoa known as the 'love drug,' PEA stimulates the release of dopamine and endorphins, contributing to feelings of pleasure and euphoria.
Endorphins and Serotonin: Cocoa triggers the release of endorphins for pleasure and contains tryptophan, a precursor to serotonin, which helps regulate mood and promote well-being.
Stress Reduction: Flavonoids and magnesium in dark chocolate may help lower the stress hormone cortisol and reduce anxiety, providing a calming effect.
Cocoa Content is Key: Dark chocolate with a high cocoa percentage (70% or more) contains higher concentrations of the beneficial compounds responsible for these mood-enhancing effects.

The Neurochemicals Behind Your Chocolate Craving

While chocolate doesn't solely raise a single hormone, it prompts a complex cascade of neurochemical responses in the brain. It's more accurate to say that chocolate influences the release and function of several hormones and neurotransmitters, which are the body's chemical messengers. The specific compounds in cocoa, especially in higher concentrations, are the key players in this process.

Endorphins: The Body's Natural Feel-Good Chemicals

When you eat chocolate, your brain is stimulated to release endorphins. These natural opioid-like substances bind to receptors in the brain, inducing a sense of euphoria and pleasure while also acting as natural pain relievers. This is often described as the 'feel-good' rush that accompanies eating chocolate.

Serotonin: The Mood Stabilizer

Chocolate contains tryptophan, an amino acid that serves as a precursor to the neurotransmitter serotonin. Serotonin plays a critical role in regulating mood, promoting feelings of well-being, and reducing anxiety. When serotonin levels are higher, individuals tend to feel calmer and more content. While chocolate contributes tryptophan, its effect on serotonin can be complex due to its protein content, which can sometimes compete with tryptophan absorption..

Dopamine: The Reward and Motivation Neurotransmitter

Often associated with pleasure and reward, dopamine is a key neurochemical influenced by chocolate. Chocolate contains a compound called phenylethylamine (PEA), sometimes referred to as the 'love drug,' which acts as a central nervous system stimulant and triggers the release of dopamine. This dopamine release occurs in the brain's reward centers.

Oxytocin: The 'Cuddle Hormone'

Some research has linked chocolate consumption to the release of oxytocin, known for its role in social bonding and feelings of intimacy and contentment. Beyond these, compounds like Phenylethylamine (PEA), Theobromine, Caffeine, Flavonoids, and Magnesium also contribute to chocolate's effects on mood and alertness.

Comparing the Hormonal Impact of Different Chocolates

Not all chocolate is created equal when it comes to its effects on your hormones and mood. The amount of cocoa and added sugar plays a major role.


Feature	Dark Chocolate (70%+ Cocoa)	Milk Chocolate	White Chocolate
Cocoa Content	High	Low (10–50%)	None (contains cocoa butter)
Hormonal/Neurochemical Impact	Highest concentrations of mood-boosting compounds (PEA, flavonoids, tryptophan). Maximizes endorphin and dopamine release.	Lower levels of beneficial compounds due to higher sugar and milk content. Less potent effect on mood.	Contains no cocoa solids, so it lacks the key mood-boosting compounds. Effects are primarily from sugar and fat.
Antioxidant Content	High	Low	None
Magnesium Content	High	Low	Low
Added Sugar	Lower	High	Highest
Overall Health Benefits	Most beneficial, supports heart and brain health.	Less beneficial, high in saturated fat and sugar.	Provides little to no nutritional benefit beyond calories.

Frequently Asked Questions

There is no single primary hormone. The pleasure felt from eating chocolate comes from the release of several neurochemicals, including endorphins, serotonin, and dopamine, which are triggered by compounds in cocoa.

Yes, several studies have indicated that moderate consumption of dark chocolate can reduce levels of the stress hormone cortisol in individuals with high anxiety, helping to alleviate stress.

Phenylethylamine (PEA) is a compound that stimulates the release of dopamine and endorphins. This can create feelings of pleasure, excitement, and a general sense of well-being, similar to the sensations of being in love.

Dark chocolate contains a higher concentration of cocoa solids and, therefore, more beneficial compounds like flavonoids and magnesium. Milk chocolate has more added sugar and less cocoa, making its hormonal impact less significant.

The craving for chocolate during PMS may be linked to hormonal fluctuations and a potential dip in magnesium levels. Dark chocolate's high magnesium and serotonin-boosting properties can help stabilize mood and ease muscle cramps.

No, the mood-boosting effect is not just a 'sugar high.' While sugar provides a temporary energy lift, the long-term positive effects are attributed to compounds in cocoa, like endorphins, dopamine, and flavonoids, especially in high-cocoa dark chocolate.

Chocolate contains the amino acid tryptophan, a precursor to serotonin. Consuming chocolate can increase the bioavailability of tryptophan, which then promotes serotonin production in the brain, leading to a feeling of happiness and well-being.
