I took St. John's Wort for a long time. I tried it for help in improving my mood, but it didn't. What it did do was help a lot with the chronic low-grade anxiety I was experiencing at the time. Knocked it right out.

The only all-natural thing I ever consumed that helped my mood noticeably was drinking whole leaf, green tea--not tea bags which is a lower quality of tea. The improvement on my mood was dramatic, and I didn't even know drinking green tea would effect my mood. (So, it wasn't a placebo effect.) There's lots of research supporting green tea's effect on mood. If you are not experiencing a major depression, I recommend you try this.

Be careful with supplements because, even though they are not regulated, they are chemicals (drugs) and can cause problems. There's research on some that they cause liver problems and other problems, and they can interact badly with other medications you may be taking.

I suggest you Google for research on supplements you are thinking of taking. And talk to your pharmacist, particularly for recommendations on reliable brands.
