The results of several clinical trials suggest that gamma oryzanol supplementation can help people with gastritis and other gastrointestinal complaints. In one study, people with chronic gastritis were given 300 mg of gamma oryzanol per day.⁵ After two weeks, 23% of people taking gamma oryzanol reported that it was “extremely effective” and 55% rated it as “moderately effective.” Another study produced similar results: People with various types of gastritis received 300 mg of gamma oryzanol per day. After two weeks, more than 62% of those with superficial gastritis, more than 87% of those with atrophic gastritis, and all people with erosive gastritis experienced improvement. These results were confirmed in a large study involving approximately 2,000 people with various gastrointestinal complaints, including several forms of gastritis.⁶ Some of these people required as much as 600 mg per day for symptoms to improve. People with gastritis wishing to take gamma oryzanol for more than six months, or in amounts exceeding 300 mg per day, should first consult with a physician.

Various amino acids have shown promise for people with gastritis. In a double-blind trial, taking 200 mg of cysteine four times daily provided significant benefit for people with bleeding gastritis caused by NSAIDs (such as aspirin).⁷ Cysteine is a sulfur-containing amino acid that stimulates healing of gastritis. In a preliminary trial, 1–4 grams per day of NAC (N-acetyl cysteine) given to people with atrophic gastritis for four weeks appeared to increase healing.⁸Glutamine, another amino acid is a main energy source for cells in the stomach and supplementation may increase blood flow to this region.⁹ Patients in surgical intensive care units often develop gastrointestinal problems related to a glutamine deficiency.¹⁰ When burn victims were supplemented with glutamine, they did not develop stress ulcers, even after several operations.¹¹ Nevertheless, it remains unclear to what extent glutamine supplementation might prevent or help existing gastritis. Preliminary evidence suggests the amino acid arginine may both protect the stomach and increase its blood flow,¹² but research has yet to investigate the effects of arginine supplementation in people with gastritis.

When H. pylori causes gastritis, free radical levels rise in the stomach lining.¹³ These unstable molecules contribute to inflammation and damage to the stomach lining. Vitamin C, an antioxidant that helps quench free radical molecules, is low in the stomach juice of people with chronic gastritis. This deficiency may be the link between chronic gastritis and the increased risk of stomach cancer. When people with gastritis took 500 mg of vitamin C twice a day, vitamin C levels in their gastric juice rose, though not to normal levels.¹⁴ In another trial, vitamin C supplementation (5 grams per day divided into several doses for four weeks) appeared to eliminate H. pylori infection.¹⁵ While no direct evidence proves that taking vitamin C reduces gastritis symptoms, scientists widely believe that any agent capable of knocking out H. pylori should help people with this condition.

Caution: Synthetic beta-carotene has been linked to increased risk of lung cancer in smokers. Until more is known, smokers should avoid all beta-carotene supplements.

The antioxidant beta-carotene may reduce free radical damage in the stomach,²² and eating foods high in beta-carotene has been linked to a decreased risk of developing chronic atrophic gastritis.²³ Moreover, people with active gastritis have been reported to have low levels of beta-carotene in their stomachs.²⁴ In a preliminary trial, giving 30,000 IU of beta-carotene per day to people with ulcers or gastritis led to the disappearance of gastric erosions.²⁵ In another study, combining vitamin C and beta-carotene also led to improvement in most people with chronic atrophic gastritis.²⁶

Demulcent herbs, such as marshmallow, slippery elm, and bladderwrack, are high in mucilage. Mucilage might be advantageous for people with gastritis because its slippery nature soothes irritated mucus membranes of the digestive tract. Marshmallow is used for mild inflammation of the gastric mucosa.²⁷

Chamomile, high in the flavonoid apigenin, may soothe injured and inflamed mucous membranes. In addition, a test tube study has shown that apigenin inhibits H. pylori,²⁸ and chamazulene, another active ingredient in chamomile, reduces free radical activity,²⁹ both potential advantages for people with gastritis. Human clinical trials are needed to confirm chamomile’s effectiveness for treating gastritis.

Goldenseal is regarded as an herbal antibiotic and has been traditionally used for infections of the mucous membranes. While no specific research points to goldenseal as a treatment for gastritis, there is some evidence from test tube studies that berberine, an active ingredient in goldenseal, slows growth of H. pylori.³⁶ Modern herbal practitioners now prefer alternatives to goldenseal, since the plant is threatened with extinction due to overharvesting.

Many of the same herbs that are helpful for peptic ulcers may also aid people with gastritis. Licorice root, for example, has been traditionally used to soothe inflammation and injury in the stomach. Its flavonoid constituents have been found to stall the growth of H. pylori in test tube studies.³⁷ However, there have been no clinical trials using licorice to treat gastritis. To avoid potential side effects, such as increasing blood pressure and water weight gain, many physicians recommend deglycyrrhizinated licorice (DGL). This form of licorice retains its healing qualities by removing the glycyrrhizin that causes problems in some people.

Zinc and vitamin A, nutrients that aid in healing, are commonly used to help people with peptic ulcers. For example, the ulcers of people taking 50 mg of zinc three times per day healed three times faster than those of people who took placebo.⁴⁰ Since some types of gastritis can progress to peptic ulcer, it is possible that taking it may be useful. Nevertheless, the research does not yet show that zinc specifically helps people with gastritis. The amount of zinc used in this study is very high compared with what most people take (15–40 mg per day). Even at these lower levels, it is necessary to take 1–3 mg of copper per day to avoid a zinc-induced copper deficiency.

Wood betony(Stachys betonica) has been used in European traditional herbal medicine for the treatment of heartburn and gastritis.
