+ 500 mg of vitamin C per serving, disclosed dose + Full ingredient transparency – each active listed individually + Budget‑friendly option within its category + Prolonged‑release format may smooth out the typical rapid surge
- Contains preservatives and artificial flavours, which few peers include - Includes added salt, also uncommon in similar vitamin C tablets - Vitamin C may modestly inhibit calcium absorption when taken together
This 21st Century vitamin C product stands out for its clear labeling of each active (500 mg vitamin C, 40 mg calcium) and its budget positioning, making it an economical choice for daily immune support. The prolonged‑release tablet aims to deliver vitamin C more gradually than standard chewables. However, it uniquely adds preservatives, artificial flavours and salt—ingredients that most comparable vitamin C tablets omit—so consumers sensitive to these additives may prefer alternatives. Additionally, the known mild interaction between high‑dose vitamin C and calcium suggests spacing the two supplements if both are used.
