500 mg a day is the most-studied vitamin C dose in the research. What 27,800 trial participants showed, and why absorption matters at this dose.

No major health authority says to take vitamin C on an empty stomach. Here is what the evidence actually shows, and what matters far more.

What exactly is liposomal vitamin C? The same ascorbic acid in a phospholipid shell — and a category of formulations, not one technology.

Acerola and camu camu juice carry 20 to 35 times the vitamin C
of orange juice. Here's the full ranking — and the absorption ceiling that caps
them all.

What does taking liposomal vitamin C do? It raises blood levels 1.3 to 7.2 times — and your cells by far less. What the research shows, and where it stops.

What does liposomal do to your body? How liposomes cross the gut wall, what the research shows about absorption, and what happens to the shell itself.

What diseases can vitamin C prevent? Just one — scurvy. What the randomized trials actually found on colds, heart disease, cancer and eye disease.

No Canadian body ranks liposomal vitamin C brands. Five checks separate a serious product from a marketing one: four on the label, one you have to ask for.

Vitamin C deficiency can cause fatigue, irritability and low mood, and in scurvy, nerve and movement problems. What the evidence shows, and what else to rule out first. 

Is liposomal vitamin C better in liquid or pill form? No trial has compared them directly. What the research actually shows, and how to choose between them.

How to check if vitamin C is low: a plasma ascorbic acid test, taken fasting and handled properly. What the numbers mean, and when testing is worth it. 

How often should you take vitamin C per day? Once is enough for most adults. Splitting only earns its keep above roughly 500 mg at a time.
