Vitamin U: It Has Got Your Back!

What is Vitamin U?

You must have read about Vitamin A, B, C, K in your primary school, but there are good chances that you have never heard of Vitamin U. Well, Vitamin U is not a true vitamin, it is a derivative of the amino acid named methionine. The derivatives of this amino acid that are termed Vitamin U in normal parlance are S-methyl methionine (SMM), methyl methionine sulfonium (SMM), and 3-amino-3-carboxypropyl dimethyl sulfonium.

Vitamin U is closely linked to several benefits for the stomach and intestine area. Although this vitamin has been in use since ancient times, it became known among the masses only recently when Dr. Garnett Cheney,  a professor of medicine at Stanford University, conducted various experiments and discovered the healing properties of this vitamin cum enzyme.

In the experiment, guinea pigs were fed with cabbage juice and the results established the anti-ulcer effects of the diet. Dr. Cheney, quite delighted at the discovery, named this vitamin after the world ulcer, and hence, Vitamin ‘U’. although the history of this vitamin is not very long, it has managed in a short time to prove itself as a potent aid in the battle against many insidious and serious diseases.

1. Anti-Ulcer Properties

When Dr. Cheney had conducted his experiment in the 1950s, a lot of research was also initiated on the same and it was suggested that drinking 1 quart or 945 ml of cabbage juice daily can help ulcers heal 4-5 times faster than the anti-ulcer therapy that was adopted generally by doctors during that period. 

However, the conundrum was whether all these properties were exhibited by this enzyme named Vitamin U or any other nutrients that were present in cabbage juice used in the experiment. Research is still ongoing to find any conclusive answers for the same.

2. Might Help Lower Cholesterol Levels

A lot of research on Vitamin U is still ongoing, which means that it is mostly not possible to give any benefits with very definite answers.

Vitamin U has been linked with lower cholesterol and triglyceride levels in a lot of studies. One study suggested that Vitamin U prevents the creation of fat cells in the body, which further helps in the reduction of triglyceride levels. More human research on this vitamin is still needed.

3. Protection to Liver, Lungs, and Kidneys

Studies suggest that Vitamin U can offer protection to your lungs, liver as well as kidneys. While most studies have mainly been conducted on different animals, the results are promising so far.

Vitamin U was found to reverse liver damage caused by valproic acid in an animal study. In a study conducted on rats, Vitamin U has also been found to be very effective in controlling liver damage, in comparison to those animals who were not fed with it. 

4. Wound Healing Properties

Vitamin U has also been linked with wound healing properties and protection from the sun’s ultraviolet rays. It can protect against burns and other damage that is caused by UV rays. There have also been suggestions from various researchers to include Vitamin U as a component in cosmetic products.
