Best Supplements for Mood
7 evidence-based options for mood, summarized from the research: what they do, how to dose them, and how they work together.
5-HTP
A direct serotonin precursor for mood and sleep, use with care.
Folate (B9)
The active B vitamin behind methylation, mood, and pregnancy health.
L-Tryptophan
The dietary precursor to serotonin and melatonin.
L-Tyrosine
The dopamine precursor that sharpens focus under stress.
Uridine
A nucleotide studied for memory, mood, and brain membranes.
Vitamin B6 (Pyridoxine)
The neurotransmitter cofactor behind mood, sleep, and homocysteine metabolism.
Vitamin D3
The sunshine vitamin behind bone, immune, and mood health.

Combinations to know
How these supplements pair with each other and beyond.
5-HTP + Vitamin B6 (Pyridoxine)
Vitamin B6 (P5P) is the cofactor that converts 5-HTP into serotonin, so adequate B6 status is needed for it to work.
Folate (B9) + Vitamin B6 (Pyridoxine)
B6 and folate work together to lower homocysteine and support methylation balance.
L-Tryptophan + Vitamin B6 (Pyridoxine)
B6 is required to convert 5-HTP into serotonin; taking it with tryptophan is a common mood stack.
5-HTP + L-Tryptophan
5-HTP is the metabolite tryptophan is converted into. It skips the rate-limiting step for a more direct serotonin boost, but stacking the two (or either with SSRIs) raises serotonin-excess risk.
Folate (B9) + L-Tryptophan
Folate supports the methylation cycle needed to recycle and activate neurotransmitter cofactors.
Folate (B9) + L-Tyrosine
Methylation via folate is required to activate cofactors in catecholamine synthesis.
Frequently asked questions
What are the best supplements for mood?
The most-researched options are 5-HTP, Folate (B9), L-Tryptophan, L-Tyrosine, Uridine, Vitamin B6 (Pyridoxine), and Vitamin D3. Each is summarised with its benefits, typical dosing, and the strength of the evidence behind it.
How were these mood supplements chosen?
These are the supplements in the Vital Matrix library most commonly used for mood, graded by the strength of human evidence. See our methodology for how we grade the research.
Can you combine supplements for mood?
Yes, several pair well. For example, 5-HTP and Vitamin B6 (Pyridoxine): Vitamin B6 (P5P) is the cofactor that converts 5-HTP into serotonin, so adequate B6 status is needed for it to work.
