Vitamin C

Should I stop taking vitamin C if my pee is bright yellow? Usually no — and the colour is probably riboflavin, not vitamin C. What each shade means. 

Is too much vitamin C hard on your kidneys? Below the 2,000mg upper limit, rarely. The stone risk, who it affects, and why the mechanism is oxalate.

How can you get 1000 mg of vitamin C naturally? About eight cups of produce a day, mostly raw — the foods that get you there, and what cooking takes away.

Do liposomal vitamins actually work? For vitamin C, 9 of 10 trials say yes. For glutathione, the better-controlled evidence backs the plain form.

What juice has 100% vitamin C? Orange juice — 93 mg per ¾ cup,
103% of the Daily Value. Why the number on the carton is not your personal target.

Does liposomal have side effects? The phospholipid carrier has a long safety record, but the toxicology of high-absorption formats is barely studied.

Which two superfoods are very high in vitamin C? Kakadu plum and camu camu. What the numbers actually mean, and why absorption is a separate question.

Should a 70 year old woman take vitamin C? Age alone does not raise the requirement — it stays 75mg. What changes after 70, and when the answer becomes yes.

Is liposomal vitamin C worth taking? For most healthy adults, no. Where the format earns its place, where plain vitamin C already does the job, and why. 

How long does liposomal vitamin C take to start working? About 4 hours to peak — no faster than regular vitamin C. Shifting your levels takes days to weeks. 

What organ does vitamin C affect? All of them - but it pools in the adrenal glands, brain and eyes, and leaves through the kidneys, where the one caution sits.

What fruit has 100% vitamin C? None — the richest is about 3% by
weight. But if you mean 100% of the 90mg Daily Value, an orange and a kiwi clear
it.
