21st Century B-100 Complex Prolonged Release Caplets, 60 Count – Sustained B Vitamin Support

Balanced B-Complex for daily routines

Meet the 21st Century B-100 Complex Prolonged Release Caplets—a daily B vitamin complex designed to release gradually over the day. The prolonged-release design aims to provide a steady supply of nutrients, helping you stay on track from morning through evening without sudden peaks. This approach mirrors how many people manage busy schedules, from work to travel, by keeping routine supplementation simple and consistent.

Prolonged release means the caplet slowly releases nutrients over several hours, offering a smoother delivery than a single-dose format. While results vary by individual, this design may support a steadier level of nutrients throughout the day as you go about your activities, meals, and errands.
