We have all heard this golden rule of health since childhood. It is well known that vitamins are crucial for our bodies:

• You need Vitamin A for healthy eyes, which you can get from carrots;
• Vitamin C to boost your immune system, available in oranges and kiwis;
• Vitamin D for strong bones, obtained through sunlight and deep-sea fish;
• And the Vitamin B complex to fight fatigue, sourced from whole grains.

These common vitamins each have their specific roles and are essential for maintaining daily bodily functions.

But have you ever heard of a nutrient called "Vitamin U"?

It is not a typical vitamin. Unlike the everyday nutrients mentioned above, it is a nutrient that specifically targets and protects the stomach, and it is widely used in the medical community!

This article explores the history of Vitamin U, uncovers its scientific mysteries, and explains exactly how it safeguards our gastric mucosa.

📍 An Accidental Discovery in Medical History: The Birth of Vitamin U

Strictly speaking, Vitamin U is not a standard dietary vitamin, but rather a natural amino acid derivative called S-Methylmethionine.

Its discovery was quite dramatic. In 1952, Dr. Garnett Cheney from the Stanford University School of Medicine conducted his famous "Cabbage Juice Experiment" while researching gastrointestinal problems. He had 100 patients suffering from severe stomach discomfort (damaged gastric mucosa) drink about one quart (roughly one liter) of fresh, raw cabbage juice daily, split into four or five divided servings, to observe the effects.

The results were a major breakthrough for the medical community at the time: patients who drank the cabbage juice saw significant improvement in their damaged gastric mucosa on an average of just 13.1 days. In contrast, the control group receiving traditional medical treatments took over a month to heal.

Dr. Cheney firmly believed that there was a substance in cabbages with a specific healing effect on the gastric mucosa, which he named "Vitamin U." Later research successfully identified the true identity of Vitamin U as S-Methylmethionine.¹

Further studies have indicated that Vitamin U may protect the stomach through multiple mechanisms. These include enhancing gastric mucosal blood flow, increasing mucin secretion, and regulating gastric acid secretion. Furthermore, the antioxidant properties of Vitamin U help maintain the integrity of the gastric mucosa, alleviate gastrointestinal tract damage, and improve overall stomach health.²

🥬 The Limits of Diet: Does Eating Cabbage Mean You're Absorbing Enough Vitamin U?

Since Vitamin U naturally exists in cruciferous vegetables like cabbage, broccoli, and kale, shouldn't eating more vegetables be enough? Theoretically, yes, but practically, it is quite difficult.

Vitamin U is highly heat-sensitive and water-soluble. Because it breaks down easily under high temperatures, everyday cooking methods like stir-frying, boiling, or simmering will wash away or destroy most of this nutrient. Unless you follow Dr. Cheney's experiment and drink a liter of raw, bitter, unpasteurized cabbage juice across four to five servings every day, simply eating cooked cabbage will not deliver the desired restorative effects.

Not only is this impractical for modern city dwellers, but consuming excessive amounts of raw cabbage can also easily trigger indigestion and other stomach discomforts.

💊 The Professional Solution: How Weisen-U Delivers Vitamin U With Precision

Since everyday dietary intake falls short of therapeutic standards, precisely formulated modern medicine is the best solution.

Weisen-U is a dry-coated tablet consisting of an inner core and an outer layer:

• The strong antacid in the outer layer dissolves quickly after intake and neutralizes excessive gastric acid, relieving stomach pain.
• Afterwards, the Methylmethionine Sulfonium Chloride (Vitamin U) contained in the inner layer penetrates the damaged sections of the stomach, quickly treating the affected areas, and promoting the recovery of the gastric mucosa.

Protecting Hong Kong's stomachs for over 65 years and reigning as the No. 1 selling antacid for 12 consecutive years, Weisen-U is the best choice you can depend on.
