Vitamin U isn’t technically a vitamin in the traditional sense, but it is a term used to describe a compound called S-methylmethionine (SMM), which is a derivative of the amino acid methionine. Although it’s not officially classified as a vitamin, it is often linked to a variety of potential health benefits.
Applications of Vitamin U
1. Gastrointestinal Health:
- Ulcer Treatment: Vitamin U is most commonly associated with its potential role in treating peptic ulcers. It has been shown to help promote healing of the stomach lining and reduce gastric acidity. It’s thought to help protect the stomach from the damaging effects of acid.
- Digestive Health: Vitamin U may help in improving overall digestive health by supporting the healing of the digestive tract and reducing inflammation. It’s sometimes used in natural medicine for conditions like gastritis and heartburn.

2. Anti-inflammatory Properties:
- It is believed to have anti-inflammatory effects, which might help in reducing swelling and irritation in the gastrointestinal tract, and could potentially help manage conditions like ulcerative colitis and irritable bowel syndrome (IBS).
3. Liver Health:
- There’s some evidence suggesting that Vitamin U could have a protective effect on the liver, helping it detoxify and regenerate. This may make it useful in promoting overall liver health.
4. Skin Health:
- Vitamin U has been included in some skincare products, especially those aimed at healing skin irritations, wounds, or promoting a healthy skin barrier. Its anti-inflammatory properties can support skin recovery.
5. Antioxidant Properties:
- Like many sulfur-containing compounds, Vitamin U may have antioxidant effects, which can help combat oxidative stress in the body.

Sources of Vitamin U: It is found primarily in cabbage and cabbage juice, though it can also be found in other vegetables like kale, spinach, and broccoli.
Although Vitamin U has shown some positive effects, research is still ongoing, and its applications and effectiveness in these areas continue to be explored.
