Essential fatty acids
Moderate evidenceEPA / DHA marine lipids
The marine fats your brain is partly built from. When mood runs low, an EPA-rich omega-3 is among the better-studied nutrients worth raising with your doctor — a supportive nutrient alongside diet and care, never a treatment on its own.

Moderate evidenceCholecalciferol
The 'sunshine vitamin' doubles as a hormone precursor involved in brain function. Low vitamin D status is consistently linked with low mood — especially in winter and indoor lifestyles.
Read the full profile →Mineral
Moderate evidenceMagnesium bisglycinate chelate
A gentle, highly absorbable form of magnesium — the mineral your nervous system uses to downshift. A favorite for evening wind-down, stress resilience and sleep quality.

Moderate evidenceB6 · B9 (folate) · B12 and co-factors
The quiet co-factors your brain leans on to build its own neurotransmitters. When B12 or folate run low, fatigue and flat mood often follow — which is why they're worth getting right before reaching further.
Read the full profile →Adaptogen
Moderate evidenceWithania somnifera
The adaptogen people reach for when stress feels relentless. It's the most studied root for everyday tension — standardized extracts like KSM-66 have, in several trials, eased perceived stress and cortisol against placebo.
Read the full profile →Amino acid
Moderate evidenceγ-glutamylethylamide
The amino acid that makes green tea calming rather than jittery. L-theanine promotes a state of relaxed alertness without sedation — useful for stress and focus alike.

ashwagandha
Can you take ashwagandha with sertraline? Usually low-risk, but added sedation and thyroid effects make a quick check with your prescriber worth it first.
magnesium-glycinate
Glycine vs collagen: collagen is roughly a third glycine, so they overlap. Glycine is the isolated amino for sleep and calm; collagen targets skin and joints.
l-theanine
Lemon balm vs bee balm: alike in name, different plants. Lemon balm is the calming herb with sleep and stress research; bee balm is mostly a culinary tea.
