S-methylmethionine, methylmethionine-sulfonium, anti-ulcer factor
Vitamin U is currently excluded from the group of vitamin-like substances.
Vitamin U is named after the first letter of the word “ulcus” (ulcer) due to its ability to heal stomach and duodenal ulcers, but modern scientists question its antiulcer effect.
