Best Supplements for Anxiety
Anxiety can have many different drivers — including chronic stress, nervous system dysregulation, inflammation, hormonal shifts, and poor sleep.
While supplements aren’t a replacement for therapy, medication when needed, or lifestyle changes, certain nutrients may help support the body’s stress response and promote a calmer baseline.
Below are the supplements I most commonly recommend for nervous system support and anxiety-related symptoms.
Magnesium Glycinate
Magnesium plays a key role in nervous system regulation and helps support GABA activity — the primary calming neurotransmitter in the brain. Many adults are mildly deficient, especially during periods of chronic stress.
Best for:
Muscle tension
Restlessness
Difficulty falling asleep
Stress-related headaches
NP-Recommended Option
Different forms of Magnesium
Omega-3 Fatty Acids
Omega-3s help support inflammation balance and healthy neurotransmitter function. Research suggests adequate EPA intake may support mood stability and emotional regulation.
Best for:
Mood swings
Irritability
Inflammation
Brain health
NP-Recommended Option
L-Theanine
L-theanine is an amino acid found naturally in green tea. It promotes relaxed alertness without sedation and may help reduce the “wired but tired” feeling that often accompanies anxiety.
Best for:
Racing thoughts
Anxiety
Situational stress
Daytime calm without drowsiness
NP-Recommended Option
Ashwagandha
Ashwagandha is an adaptogenic herb that may help regulate cortisol levels in individuals experiencing chronic stress.
Best for:
Stress related fatigue
“Burned out” feeling
Sleep disruption linked to stress
Avoid if:
Hyperthyroidism
Pregnancy
Certain autoimmune conditions
NP-Recommended Option
Anxiety Stack
When Supplements Aren’t Enough
If anxiety is persistent, worsening, or interfering with daily functioning, it’s important to seek evaluation from a healthcare provider. Supplements can be supportive, but they are not a replacement for appropriate mental health care when needed.
