The startle reflex—those sudden, involuntary jumps or jerks in response to unexpected sounds, movements, or sensations—is a normal part of the nervous system’s protective response. However, when the reflex is overly sensitive or frequent, it can interfere with daily life, causing discomfort, fatigue, or even anxiety. Factors like stress, nutrient deficiencies, or nervous system imbalances can make the reflex more pronounced.
Natural supplements may provide gentle support by calming the nervous system and improving how the body responds to stimuli. Some nutrients are particularly helpful in stabilizing nerve signals and reducing overreactive responses.
Here are two evidence-based supplements that may help with an overactive startle reflex.
Magnesium
Magnesium is a key mineral for calming the nervous system and regulating muscle contractions. Deficiency can make the nervous system more excitable, leading to twitching, spasms, and an exaggerated startle response. Supplementing with magnesium may help relax muscles, improve nerve stability, and reduce sensitivity to sudden stimuli.
- Mechanism of action: Calms overactive nerve signaling by regulating calcium flow into cells
- Dosage or usage tip: 200–400 mg daily, best taken in the evening for relaxation benefits

L-Theanine
L-Theanine, an amino acid found naturally in green tea, promotes relaxation without drowsiness. It supports the production of calming neurotransmitters like GABA and serotonin, which can reduce nervous system overactivity. This makes it a useful option for easing exaggerated startle responses linked to stress or anxiety.
- Mechanism of action: Promotes neurotransmitter balance and reduces stress-related nervous system excitability
- Dosage or usage tip: 100–200 mg daily, often taken in the morning or before stressful situations

Summary
An overactive startle reflex can be disruptive, but targeted supplements may help calm the nervous system. Magnesium helps relax muscles and stabilize nerve signaling, while L-Theanine promotes neurotransmitter balance and reduces nervous tension. Together, these supplements can provide gentle support for a calmer, more balanced response to sudden stimuli.
As always, consult with a healthcare professional before starting new supplements, especially if the startle reflex is severe or associated with other neurological symptoms.
