I believe that the confusion arises from trying to extrapolate useful information from a nutritional or medical study considering one or two nutrients that is being evaluated using analysis of the variance -ANOV. Human biology is much more complicated as the interaction of many nutrients gives us health or disease. After decades of making the same error, manufacturing has been able to overcome this confusion by using analysis of the means. ANOM gives not only the outcome of the principle inputs but also the interaction of the various inputs. Until better methods are adopted by medical/nutritional research, we are just left with the best guess interpretation of the ‘experts.’
So where does that leave us? I believe it is about what gives you health or disease. I have been supplementing with the nutrients in which we are deficient for eight years now. The interaction and the amounts of daily intake of vitamin D, vitamin A, vitamin C, sulfate, iodine, and magnesium are critical. When I have started to feel bad or had other less than desirable symptoms, I have found that I have to change the balance of one of these deficiencies.
After much trial and error this is where I am now in units per pound of body weight per day:
Vitamin D3 40 IU
Vitamin A from fish liver Oil 20 IU
Vitamin C 20mg
Magnesium 4.5 mg
Iodine 0.05mg (example 150 lb weight - 7.5mg)
This of course says nothing of the other nutrients from diet and supplementation that are essential to health. However, the ones listed above are typically difficult if not impossible to get from the American diet.
These amounts and the sources that you derive the nutrients from may be different for you as our bodies do not all process a given nutrient the same way. This is due to the fact that we may be deficient or have an over abundance of other nutrients in our bodies to say nothing of our state of health. Let’s examine an example and you can see what I mean.
Suppose you have low energy and feel cranky. Knowing that magnesium is responsible for the action of over 300 enzymes you may decide that you need to increase magnesium. However, there are several other things that may be the problem even if you are getting enough of the above nutrients. It may be that you are not absorbing enough vitamin B12 because of your age. Or, it could be that you are not getting enough of the correct types of fats and proteins. Or, it may simply be that you are eating too much sugar and you blood sugar spikes are the issue, etc.
Eating a great diet of fruits, vegetables, grains, nuts, and meats while supplementing with the nutrients in which you are deficient will give you optimum health. It is only through your record keeping of how you feel, trial and error of amounts, and types of foods that are consumed can you reach this desire. There is no magic formula. There is magic for health when the balance of nutrients is correct -Pandemic Survivor
