Mood support should be considered when someone has a persistent feeling of sadness or loss of interest in life. Behavioural and physical signs that may be associated with this include; changes in sleep, appetite, energy levels, concentration, daily behaviour or self-esteem. However, there are several supplements that may help with both physical and emotional concerns and provide necessary, ongoing support. It may take some time as many supplements actually become more effective the longer you take them, so don't be disappointed if you don't notice immediate results.
