Have anyone tried using custom vitamins and minerals yet? On Vitaganic.com you can make your own multivitamin and mineral from scratch. You can make it however you like with many options.
The price is a bit high compared to many other “complete” multivitamin and minerals, but this does have almost all of what you need, so i figured it might be cheaper in the end, because you don’t have to buy separate supplements like all Soylent users have been forced to do, to meet the RDA requirements.
Maybe someone can compare the price with this all in one meal replacement pill, to your individual supplemented Soylent recipe.
