Boost is awesome! I like it - I used to work at a hospital and drank is ALL the time. It's great for diabetics. Never dumpstered any.
My personal wintertime (note - wintertime) health supplement(s) of choice is a regimine of raw garlic marinated in bragg's amino acids, detox tea, a tinctcure with elderberry and western red cedar in it, lots of citrus, ginger and raspberry water (made from fresh ground ginger and squished up raspberries, drink the water, eat the spooge at the bottom) and a ginseng and ginko tea to help bat away the wintertime blues.
I always wondered what Milk Thistle was for though - thanks for that!
