These appear to be the best multivitamins available as they are the only actual food/plant based one available. Food based vitamins can have up to 50x potency of synthetic ones (see anti-oxidant research comparing ascorbic acid to oranges) due in part to co-factors involved. Food based vitamins and minerals are also considerably more effective for disease prevention than synthetic forms (see calcium from food vs supplements for colon cancer, Hypertension, atherosclerosis... prevention). Would love to see Garden of Life conduct a research investigation on the long term effects of this product on hard outcomes for mortality, cancer, alzheimers, heart disease, infection... and I am happy to help conduct this study, if so (feel free to contact). I have been squeamish about taking multivitamins for 10 years - feeling that too much clogged the system - but now have been consuming these regularly (1/2 to 1 tab per day) with healthy nutrition from food. I notice a difference in energy and vigor when I don't take for several days. Have been and looks like I'll be continuing to recommend these to patients, friends and family in the foreseen future. Some people less experienced with taking multivitamins, however, do like other reputable multivitamins better than this product. I imagine they are enjoying the feeling of saturating their system with vitamins and minerals but that this sense won't last after long term usage. In love and service and health and love, Dr. Rober
