I highly recommend people going out and getting some supplements, good brands.
Magnesium is one that is very important! Try finding a supplement with a mix of calcium and magnesium
'Magnesium is an old home remedy for all that ails you, including "anxiety, apathy, depression, headaches, insecurity, irritability, restlessness, talkativeness, and sulkiness."
B-Complex are highly needed to deal with stress and anxiety. I have noticed a huge difference taking this for a month. Most complex's have high amounts of B's which is intimidating at first but you can always split the tablet or capsule in half and see how it works for you.
Fish oil brands make a huge difference when buying fish oil. Great brands are,
