How Exercise Increases BDNF and Improves Your Brain

Did you know that training not only transforms your muscles, but also your brain structure?

The key lies in a revolutionary protein: BDNF (Brain-Derived Neurotrophic Factor).

Often described as the “fertilizer” of neurons, BDNF is essential for learning, memory, and mental health.

BDNF is a fundamental protein for brain health, as it promotes neuron survival, stimulates the creation of new neural connections, and enhances brain plasticity.

• Low levels of BDNF have been associated with cognitive decline, depression, and neurodegenerative diseases.

The good news is that physical exercise is one of the most powerful stimuli to naturally increase BDNF, making it a key tool to improve mental performance and protect the brain in the long term.

Relationship between exercise and BDNF

The connection between movement and the mind is profound. BDNF belongs to a family of proteins called neurotrophins, whose function is to help neurons survive, grow, and connect with each other.

Studies on exercise and increased BDNF

Science is clear: even a single exercise session can make a difference. This acute increase suggests that the brain enters a “plasticity state” right after training, facilitating the assimilation of new information.

For example, sessions of intense aerobic exercise or interval training (HIIT) cause an acute increase in BDNF a few hours after training. This effect appears to be related to the metabolic stress and neuronal activation generated by demanding exercise.

Long-term training and BDNF

Beyond the acute effect, regular training over weeks or months produces sustained adaptations in the brain.

Continuous exercise programs have shown:

Differences depending on exercise modality

Not all exercises stimulate BDNF in the same way, although they all add up:

• Aerobic Exercise: activities such as running or swimming at moderate-to-high intensity seem to be the most consistent stimuli for BDNF release.
• HIIT (High-Intensity Interval Training): research suggests that intensity is key. HIIT can raise BDNF more markedly than low-intensity continuous exercise.
• Strength Training: although initially thought to have less impact, recent studies confirm that weight training also increases BDNF, while adding unique metabolic benefits.

How does exercise cause an increase in BDNF?

The process is a marvel of human biochemistry.

Exercise activates multiple molecular mechanisms that stimulate BDNF production in the brain. One of them is the inhibition of HDACs (histone deacetylases).

These enzymes normally “block” the expression of certain genes. When they are inhibited through exercise, the genetic brake is released, allowing the BDNF gene to be expressed more strongly and more neurotrophic protein to be produced.

Likewise, when we exercise, muscles release substances that travel to the brain, with two key molecules being:

Benefits of increasing BDNF through exercise

Raising BDNF levels through exercise has direct and highly relevant effects on brain health:

Improves cognitive level and memory

BDNF is essential for learning and memory. Higher levels promote:

• Greater neuronal plasticity.
• Better memory consolidation.
• Greater learning capacity and concentration.

This is why training regularly can translate into better intellectual performance and greater mental agility.

Prevents neurodegenerative diseases

BDNF participates in neuroprotective mechanisms that help to:

• Protect neurons from damage.
• Reduce neuronal loss associated with aging.
• Slow processes related to diseases such as Alzheimer’s or Parkinson’s.

Although it is not a cure, exercise is one of the most effective strategies to care for the brain in the long term.

Supports mental health

There is a strong relationship between exercise, BDNF, and emotional health. Various studies show that increased BDNF is associated with:

• Improved mood.
• Reduction of depressive symptoms.
• Greater resilience to stress.

This explains why exercise is considered a key tool in the prevention and support of mood disorder treatment.

Your exercise plan to increase BDNF

To effectively stimulate BDNF, there’s no need to overcomplicate things:

Try HSN Brain Care to boost your BDNF

Training is not just about aesthetics or physical performance. It is one of the best investments you can make for your brain health, mental performance, and emotional well-being.

At HSN, we are committed to a holistic approach to training: strong body, healthy brain. That’s why we introduce our formula Brain Care, designed to support brain function in active individuals, students, and anyone who wants to perform better mentally.

What is HSN Brain Care?

Brain Care is a supplement formulated to support and optimize brain function, combining scientifically backed ingredients related to memory, concentration, learning, and neuronal protection.

It does not replace exercise—the main stimulus for increasing BDNF—but it acts as a nutritional support, helping to create a favorable brain environment similar to that promoted by regular training.

Key ingredients and their role in brain health

The Brain Care formula includes nutrients directly involved in neuronal plasticity and cognitive performance:

As we’ve explained, physical exercise—especially aerobic and strength training—is one of the most powerful stimuli to increase BDNF, a key factor for neurogenesis, synaptic plasticity, and memory.

These nutrients enhance and sustain that effect through:
