I have always been interested in Vitamin C as a classic example of mayhem from the absence of essential modality!
I truly believe that the elimination of scurvy on British Warships during the Napoleonic wars allowed Britain to ‘rule the waves’! But Linus Pauling, a two time Nobel Prize winner was always been interested in Vitamin C as a treatment for cancer.
He was on the right track, but in those days had not mastered the intravenous approach.
Our bodies, given a fairly low dosage, eliminate Vitamin C. To achieve the kind of miracle treatment that Pauling was after required an intravenous approach.
The reasoning is now clear and Michael Greger succinctly sets this out!
Essentially taking supplements is useless, assuming a plant and to some degree fruit-based healthy diet! I personally gave up Vitamin C supplements a long time ago!
Is it possible to consume up to 200 mg of Vitamin C a day without taking supplements?
No problem. A single serving of fruits and vegetables may have about 50 mg each. So just five servings of fruits and veggies a day could get us to optimum blood levels.
When we take supplement through fruit such as orange we absorb about 90%.
with supplements up in the 1250 mg range only half is absorbed at the intestinal lining level.
There is a sense that our bodies do not need higher levels of Vitamin C.
That is the first level cut back.
But then we have this 200 mg maximum tolerance level. After that our body either cuts back as above or pushes out most excess through the kidneys and bladder!
We will always ‘pee and poop’ out, one way or another, the excess! This keeps our blood levels in that narrow range of 70 to 80 micromoles per liter.
Michael Greger was able to confirm that hypothesis using disease data.
For example, at what daily intake of vitamin C is there the lowest stroke risk?
Apparently, at about 200 mg a day.
Dietary intake was associated with lower stroke risk, whereas supplements were not.
Consistent with the overall body of evidence showing that antioxidant supplements, in general, don’t seem to protect against heart attacks or strokes.
Vitamin C Blunder? Intravenous? Supplement Triggers Waste!
