Vitamin U is a term introduced in the early 1950s to identify a compound in cabbage juice. Despite its name, vitamin U is not a true vitamin but rather a derivative of the amino acid methionine (một).
Examples of methionine derivatives often called vitamin U include S-methylmethionine (SMM), methylmethionine sulfonium (SMM), and 3-amino-3-carboxypropyl dimethylsulfonium.
Vitamin U is available not only as a supplement but also found naturally in various foods, particularly cruciferous vegetables like cabbage, broccoli, Brussel sprouts, and kale (một).
Plus, cosmetics companies may add it to certain creams, serums, face masks, and other products.

Benefits and uses
Vitamin U is most often advertised as a treatment for stomach ulcers, though it’s also touted to improve digestion, strengthen immune health, protect against food allergies, lower cholesterol, and hasten wound healing.

However, research is limited. Only a handful of these benefits are currently backed by science.
May help stomach ulcers heal
When vitamin U was initially researched in the 1950s, some studies suggested that drinking một quart (945 mL) of cabbage juice daily helped gut ulcers heal 4–5 times faster than the standard anti-ulcer therapy available at the time (2, 3, 4).
Yet, researchers couldn’t confirm whether these effects were due to vitamin U or multiple nutrients.
Since then, few studies have examined the topic. To determine whether vitamin U is truly effective against ulcers, more research is needed.
May protect your lungs, liver, and kidneys
Vitamin U may safeguard your lungs, liver, and kidneys from damage.
In an animal study, vitamin U helped reverse some of the liver damage caused by the common anti-seizure medication valproic acid (5).
In another study, rats given vitamin U experienced less severe kidney damage after receiving valproic acid than those given no vitamin U. This substance also appeared to reduce markers of inflammation (6).
Animal research further suggests that vitamin U may help reduce lung damage resulting from epileptic seizures (7).
Still, human studies are necessary.

May lower cholesterol and triglyceride levels
While some evidence supports the notion that vitamin U supplements help reduce cholesterol and triglyceride levels, evidence remains weak.
For instance, one test-tube study suggests that vitamin U may prevent the creation of fat cells and reduce triglyceride levels, but few relevant human studies exist (8).
In an 8-week study, people given một.5 grams of vitamin U per day experienced no change in triglyceride levels, higher HDL (good) cholesterol, and an almost 10% reduction in total cholesterol. Yet, this study is very dated and included few participants (9).
As such, more human research is needed.
May aid wound healing and skin protection
Vitamin U may offer some protection against the sun’s ultraviolet (UV) rays, as well as expedite wound healing.
Test-tube and animal studies report that applying vitamin U directly to wounds may speed wound closure. Moreover, vitamin U appears to protect against burns and other damage caused by UV rays (10, 11, 12, 13).
Based on these findings, some researchers suggest that certain cosmetics should be formulated with vitamin U.
Yet, a lack of human research means that further studies are necessary.

Vitamin U is likely safe when eaten directly from whole foods. However, little is known about its safety or potential side effects in supplement form.
Therefore, it’s likely safest to rely on vitamin-U-rich foods like cabbage, broccoli, Brussel sprouts, and kale to boost your intake of this compound.
According to the European Chemicals Agency, vitamin U may cause eye, skin, or lung irritation if it comes into direct contact with these organs. Thus, you may want to use caution with skin care products containing this compound (14).
