Product Comparison
Compare the three vitamin C forms head-to-head — the studied-dose tablet, the liposomal premium, and the buffered alternative. In vitamin C's comparison, the honest principle is: the absorption ceiling governs everything, and the dose should match the evidence, not the megadose mythology.

Did you know?
The absorption ceiling
The intestinal transporter saturates at roughly 200 mg per sitting — the megadose tablet's excess is unabsorbed. Split doses or the liposomal delivery manage the ceiling; the 'maximum strength' label ignores it.
The cold verdict
Regular supplementation shortens colds by ~8% in adults (~14% in children) — modest, real, and NOT prevention. The Cochrane verdict, honestly sized against the megadose shelf's claims.
The urate effect
The gout meta's finding: ~500 mg/day lowers serum urate modestly — the adjunct dose our gout page features. Real, modest, and nowhere near allopurinol — honestly graded throughout the estate.
The stone ceiling
Doses above ~1,000 mg/day raise urinary oxalate and stone risk (the cohort ~19% signal, the mechanism direct) — the megadose habit's real cost, shared with the kidney-stones page.
The food route
A red bell pepper (~190 mg) covers the RDA twice over — the food-first truth: for the eating-well population, the pepper beats the pill on dose, cost, and the matrix.
The RDA honesty
The requirement is a fraction of the shelf's grams — the 10 mg scurvy floor, the 75–90 mg margin, and the megadose mythology above. The dose ladder this page teaches.
