The classic form of vitamin C. Supports immunity, collagen production, and iron absorption.
Not prevent, but it reduces cold duration by about 8% (roughly half a day) when taken daily. More effective for people under physical stress (athletes, military).
Partly true. Your body can only use so much. Absorption drops above 200mg, and excess is excreted. But your tissues do benefit from maintaining saturation.
Only if you have a sensitive stomach. Sodium ascorbate or calcium ascorbate are gentler. Same vitamin C once absorbed.

Some ingredients build up over weeks. Others act fast.
The compound effect of consistent dosing.
Check the cautions section if you have a pre-existing condition.
Some ingredients you feel. Others just work in the background.
Probably not. It may improve absorption at high doses, but for 200-500mg, regular ascorbic acid works fine. Liposomal costs 10-20x more.
Yes. Above 2000mg/day, you risk diarrhea and kidney stones (in susceptible people). The tolerable upper limit is 2000mg.
Yes, significantly. Heat and water exposure reduce it. Raw or lightly cooked foods retain the most.
Chemically identical. Your body can't tell the difference. Save your money and buy regular ascorbic acid.
Evidence supports 1-2g/day during illness to slightly reduce duration. Start at the first sign of symptoms.
Most research uses 0.5g daily. Below 0.1g, you're probably wasting money. Above 1.0g, no extra benefit. The curve plateaus. Safe upper limit ~ 2.0g.
Electron donor that regenerates other antioxidants (vitamin E, glutathione). Essential cofactor for collagen hydroxylase enzymes. Supports immune cells including neutrophil function, lymphocyte proliferation, and antibody production.

Most commercial ascorbic acid is produced by the Reichstein process or modern two-step fermentation from glucose (corn-derived). Involves bacterial fermentation followed by chemical steps.
