Quick answers
Common questions
What exactly is Vitamin U?
Vitamin U is a simpler name for S-methylmethionine. S-methylmethionine occurs naturally in raw cabbage and other brassica vegetables.
It’s not technically a vitamin. Researchers in the 1950s called it “Vitamin U” while studying it, the U stands for ulcers.
What does Vitamin U do?
S-methylmethionine supports stomach lining health. Your stomach is lined with a layer of protective mucosa. S-methylmethionine acts as a methyl donor and helps maintain that lining.*
How do I take it?
One to two capsules per day, with a meal. Each bottle has 60 capsules.
What are the benefits?*
- Supports stomach lining health
- Helps maintain the protective mucosal layer of the stomach
- Acts as a methyl donor and antioxidant
- Supports normal digestive comfort
Who is it for?
VitaminYOU is for adults who want to support their stomach lining health. It is a dietary supplement, not a medication.
Vitamin U vs. cabbage juice - what's the difference?
They work the same way. S-methylmethionine is the active compound in raw cabbage juice. When people drink cabbage juice for stomach issues, Vitamin U is what they’re getting. VitaminYOU skips the juice and delivers 500 mg of the compound directly. No fiber, no goitrogens, no liter a day.
Is Vitamin U backed by research?
\S-methylmethionine has been studied since the 1950s, with research from the US, Japan, and Eastern Europe examining its role in supporting the stomach’s mucosal lining and digestive health. It is not a pharmaceutical drug and has not gone through FDA drug approval trials.
Is VitaminYOU high quality?
Yes. VitaminYOU is manufactured in the USA in GMP-certified facilities. Every batch is tested by a third-party lab for purity and potency. If you are not satisfied, we offer a 30-day money-back guarantee.

As a person who’s been struggling with gastritis for years, I wish I knew about this product earlier, because I haven’t had any symptoms since the day I started taking it. What a game changer!
