Foods to even out the mood

The recent studies showed that fish and flaxseed were the most efficient foods to fight depression and bad mood. They contain Omega-3 fats that have many more health benefits including their heart protecting effects.

The clinically proved supplement 5-HTP (or it's herb equivelent, St. John's wart) due to its positive effect on brain serotonin (mood controller) is very good not only for depression but for fibromyalgia - a medical "mystery" condition, which is in direct connection with sleep quality. During mood swings, there's often too much or too little sleep and it's possible to manage the swings by normalizing sleep duration and structure.

Exercise is a very good treatment for mild-to serious levels of depression.
