Core Tip	This prospective, multicentre, randomized study compared complete examination rates, bowel preparation quality, diagnostic yield, and tolerability across three small-bowel capsule endoscopy protocols. A total of 261 patients from two Portuguese university-affiliated hospitals were included. After the capsule reached the small bowel, patients received one of three boosters: (1) 1 L of polyethylene glycol; (2) 1 L of polyethylene glycol plus ascorbic acid; and (3) 1 L of water. Outcomes were similar across groups, with higher tolerability in protocol 3. Thus, using 1 L of water as a booster was better tolerated without reducing examination completeness, bowel preparation quality, or diagnostic yield.
