Nutrients Involved in Mood support

Last updated: August 9, 2026

5 nutrients Tavita's library ties to mood support, framed as support — never as a promise that any one of them will get you there.

This grouping is Tavita's own editorial reading of NIH Office of Dietary Supplements fact sheets — it isn't a transcription of a single published table. The established or emerging label next to each nutrient reflects the strength of the evidence behind it, not a guarantee of an effect for you. See the methodology page for how the library is built and verified.

This is educational information, not medical advice. Talk to your clinician before changing your supplement routine, especially if you take medication or manage a condition.

How to read the evidence tier

Established

Human trials support this nutrient moving this system for a typical person, not just a lab or animal mechanism.

Emerging

A plausible mechanism with mixed, preliminary, or limited-population evidence — often shown mainly in people who were already deficient.

Nutrients involved in mood support

Magnesium Emerging
Involved in hundreds of reactions including energy production, muscle and nerve function, blood sugar control, and bone structure.
Omega-3 EPA Emerging
A marine omega-3 fatty acid that supports heart health and helps regulate the body's normal inflammatory response.
Vitamin B12 Emerging
Keeps nerve cells and red blood cells healthy and works with folate to make DNA. Mainly found in animal foods.
Vitamin B9 (Folate) Emerging
Needed to make DNA and new cells, and especially important before and during pregnancy for healthy fetal development.
Vitamin D Emerging
Helps your body absorb calcium for strong bones, and supports muscle and immune function. Your skin also makes it from sunlight.
