I am not an expert on choline, except to know that it is an essential nutrient for the human body and that Michael has recently come out against some forms of it, due to at least one study showing an association with heart disease. I also know that it is an ingredient that takes up a lot of volume in Vimmortal and is a bit more expensive ingredient. By cutting out the choline we could reduce the pill count for the daily dosage and reduce the cost of Vimmortal 2.0.
However, since it is an essential nutrient and Vimmortal is supposed to be a comprehensive multi, then I still lean toward keeping at least a little in the formulation. What about using a small amount of a better form of choline?
