Does B12 boost your energy levels?

It depends.  If your diet is deficient in B vitamins then a B12 supplement will boost your energy levels.  If you already get enough from your diet then the vitamin supplement will have no effect.  Personally, I find that a B vitamin taken 30 minutes before my morning workout gives me an energy boost.

I don't think so.  It can help you build muscle though, and having more muscle speeds up your metabolism.

You can find a ton of vitamin B in red meats and dark leafy greens. So good for you!

The chemical nature of peanut butter makes it a great, all-natural energy supplement. You've got a lot of protien and sugar in easily digestible form, which means a lot of energy really quickly.

Be sure you are using a good mulitivitamin to help boost your energy levels.  Also you may want to try drinking a product that will help replace your electrolytes after such a work out.

it is B-12. B group vitamins are for energy, so i guess they could be used to treat fatigue.

Vitamin B-12 is supposed to be good for building energy if taken regularly. My husband swears by them.

Protein is a healthy energy source. I don't know about the sugar it sound like to much. There is a energy drink at the site below that has no sugar and will give you tons of energy.

If you take too much B12, you will lose what you don't need through urinating.  The only vitamins that can be dangerous to mega-dose on are A, D, E and K.  Those four vitamins are fat soluble, and do not leave your body when you take a mega-dose.  So, you are safe.

Really the only way to gain energy is eating.  I have found that if I take B6 and B12 vitamins in the AM and maybe midday depending on the dose I am able to stay alert and focused all day.

Anything in large amounts is bad, but a ice cold beer on a hot summers day is good, not because it's intoxicating, but because it's refreshing and relaxing. About the vit b12 i have no clue, but i have heard that a beer or glass of wine a day can help prevent a heart attack, then again i could be misinformed about it so don't quote me.
