Were I manufacturing my own life extension supplement I would include the following. By the way, to get this all in one day, it is necessary to take 6 to 12 large tablets daily, usually spread throughout the day, taken a few at a time with each meal. If you compare my suggested formulation to another one, keep in mind that variations of 25 percent one way or another won't make a significant difference, and adding other beneficial substances to my recommendations probably is only helpful. However, I would not want to eliminate anything in the list below, it is the minimum: Beta-Carotene 25,000 iu Selenium 100 mcg Vitamin A 5,000 iu Taurine 500 mg B-1 250 mg Cyctine 200 mg B-2 50 mg Gluthaianone 15 mg B-3 niacinamid 850 mg Choline 650 mg B-5 750 mg Inositol 250 mg B-6 200 mg Flavanoids 500 mg B-12 100 mcg Zinc 35 mg PABA 50 mg Chromium 100 mcg Folic Acid 500 mcg Molybdenum 123 mg Biotin 200 mcg Manganese 5 mg Vitamin C 3,000 mg Iodine (as kelp) 10 mg Vitamin E 600 iu Co-Enzyme Q-10 60 mg Magnesium 1,000 mg DMAE 100 mg Potassium 100 mg Ginko biloba 120 mg Calcium 1,000 mg Vitamin D-3 200 iu Please also keep in mind that there are many other useful substances not listed above. For example, every day I have a "green drink," an herbal preparation containing numerous tonic substances like ginseng and also various forms of algae and chlorophyll extracts. My green drink makes my body feel very peppy all day, so it certainly enhances my life and may extend it. It costs about $25,00 a month to enjoy that. I also use various pure amino acids at times. Phenylalyanine will make me get more aggressive whenever I am feeling a little lackluster; this nutrient has also been used as an effective therapy against depression. Melatonin taken at bedtime really does help me get to sleep and may have remarkable life-extending properties. Other amino acids help my body manufacture growth hormones and I use them from the time I begin training seriously in spring through the end of the summer triathlon competition season. Pearson and Shaw's book (see Bibliography) is a good starting point to begin learning about this remarkably useful subject. The Future Of Life Extension I beg the readers indulgence for a bit of futurology about what things may look like if the life extension movement continues to develop.
