What's the difference between all the different B Vitamins? And what does Vitamin-B complex & Complete B Vitamins mean?

Vitamin B comes in tons of different forms. B12 and B6 affect your mood and can stabilize your emotions. They also provide excellent balance when it comes to your electrolytes. When your electrolytes get out of whack, your entire body will feel bad. Electrolytes are all the minerals, vitamins and nutrients that make your body function normally on a day to day basis. Things that affect your electrolytes are the amount of water you drink, what kind of foods you eat, temperature changes such as extreme cold or extreme heat, the ability to sweat and cool off...the list goes on and on.
