A great vitamin combo I discovered through trial and error (and probably research) is b12, magnesium and zinc after workouts — well .. before going to bed rather.
Now that I HAVEN’T worked out in about… err… 10 years [I can still push a car out of a ditch with one arm and steady body even with a crap back – had to do it 6 months ago while everybody else was struggling tongue emoticon ] – I noticed a nice benefit to the combination… even just magnesium + zinc (standard amounts):
It works like a tranquilizer. Mild. Anti-anxiety. I actually use it before going to the dentist.
