Things for quick, natural energy boost? (no Red Bull type stuff)?
Answer: B-12 is great for energy, as is ginseng..
I've found that if my PH levels are sour, an alkaline water can do wonders. My health food store carry the brand Evamore for about $1 a bottle. Or you can find the pricey ($3) Pentawater lots of places.
Liquid ginseng extracts help. I prefer the American ginseng as unwilling the Red Korean. Some ginseng products also have bee propolis and honey in them. Taste polite and helps boost the effectiveness of the ginseng.
Spirulina products back with energy. The powdered drink mixes similar to Green Lightning probably work best but if you can't tolerate the grainy, green taste, buy it contained by a pill at any health food market.
