selenium decreases stress and increases (positive) self confidence by allowing you to be yourself. i find it one of the best mood stabilizers with an ability to decrease mind chatter a great deal. add benefits to the immune system, liver, bones etc. this is maybe the one supplement i'll be staying on for life. (agree with other reviewer, better to split the capsules and mix it in drink. has a fresh almost citrusy taste dissolved in plain water.) feels great supporting a company that works on a NO FILLER policy as well. that deserves a tinge of admiration.
