Taking a natural supplement to improve mood is certainly an appealing prospect. Finding a supplement that works means we might not need to take antidepressants, which can have a variety of side effects.
The mood enhancing supplement we have had the best feedback on is 5-HTP which can help lift depression, improve sleep and eliminate migraines. It works by increasing serotonin, the neurotransmitter responsible for making us feel happy. If you buy 5-HTP make sure it is a good quality product. 5-HTP should not be taken at the same time as antidepressants without supervision from your doctor.
Food plays a role in our moods so aim for a nutritious, balanced diet. Make sure you are getting enough B vitamins, including Niacin and also eat oily fish, or take fish oil supplements. People suffering from depression have low levels of omega 3, and countries that eat a lot of fish, have decreased levels of depression.
