Analysis

Vitamin C prolonged‑release tablets delivering 1,000 mg per serving in a 110‑tablet bottle.

+ Fully disclosed 1,000 mg vitamin C dose per tablet. + Prolonged‑release format aims for steadier plasma levels. + Vegan, gluten‑free and non‑GMO, positioned as a budget‑friendly option. - Contains preservatives/artificial flavours, which few peers include. - Includes added salt, also uncommon in this category.

This supplement stands out by pairing a high 1,000 mg vitamin C dose with a prolonged‑release matrix, while being transparent about each active’s amount. It is marketed as an affordable choice and meets vegan, gluten‑free and non‑GMO criteria. However, the formulation adds both preservatives and salt—ingredients that only a small minority of comparable products use—potentially less appealing to consumers seeking a clean‑label vitamin C tablet.
