No, supplements absolutely DO NOT work outside of corner cases.
You take 100 grams of apple, it contains 5mg of vitamin C in isolate.
But if you dunk the whole 100gram of apple into the test solution, the result is 1250mg of vitamin C reactivity.
2-conditions, There are other chemicals in apples that mimic vitamin C, and/or, there are other chemicals that boost vitamin C's reactivity
Vitamin C does not exist in isolate in nature, so did a person eat 5mg of vitamin C, or 1250mg from 100g bite of APPLE.
Pulling out "Stuff" in isolate from REAL FOOD is remarkably STUPID and reductionist.
Everything in nature is designed over millions of years to work in tandem and in a complexity that our current reductionist-science can not yet comprehend.
The vitamins/ supplements market is designed by morons, aka humans.
REAL FOODS, are designed by the collective adversarial intelligence network of the universe.
Whatever it is that NT is feeling from not chugging chemical sludge is not deficiency, it's ignorance.
