You need B vitamins for your mitochondria to produce energy from glucose. Most of us absorb the B vitamins well (either in liquid or pill form), but 99 percent of us don't get enough from our diets. Take a multivitamin in the morning and evening (twice a day to keep stable levels, since we pee the water-soluble ones out) to keep you energized. Get your B and D levels checked yearly. You may be the rare person who doesn't absorb these well from your stomach and intestine and needs a B vitamin injection yearly. Much of the world is short of vitamin D - and you need it to help fight cancer, to keep arteries young, and to aid brain function. So make sure you get it measured and take what is needed to keep its level normal.
