Calculating the RDA for minerals
How was the Recommended daily allowance for minerals established?
The recommended dietary allowance (RDA) was developed during World War II by Lydia J. Roberts, Hazel Stiebeling, and Helen S. Mitchell, all part of a committee established by the United States National Academy of Sciences in order to investigate issues of nutrition that might "affect national defense".
Acourding to httpss://www.nap.edu/read/1349/chapter/2:
"Recommended Dietary Allowances (RDAs) have been prepared by the Food and Nutrition Board since 1941.
The first edition was published in 1943 to provide ''standards to serve as a goal for good nutrition."
Because RDAs are intended to reflect the best scientific judgment on nutrient allowances for the
maintenance of good health and to serve as the basis for evaluating the adequacy of diets
of groups of people, the initial publication has been revised periodically to incorporate new scientific
knowledge and interpretations. This is the tenth edition
RDAs are defined in Chapter 2 as the levels of intake of essential nutrients that,
on the basis of scientific knowledge, are judged by the Food and Nutrition Board to be adequate
to meet the known nutrient needs of practically all healthy persons."
Since the RDA for minerals was established in 1941, they had to use tablets or capsules of minerals.
The RDA has never taken into account for the efficiency of angstrom minerals @ 99.9% absorption.
The information they had to go from was at the rate of absorption of tablets and capsule which are approximately 5%. Meaning you get 5% of the mineral you take in a tablet or capsule and the rest passes out of your body unused- Less efficient.
