Gamma-Oryzanol

What Is It?

Although it appears in grains such as barley and corn, gamma-oryzanol is extracted from rice bran oil for commercial purposes. In Japan, this concentrated mixture of ferulic acid and other compounds is commonly added to foods and beverages. The bulk of research on gamma-oryzanol’s health benefits has been done in Japan, although supplements are now available in the United States as well.

Apparently acting on the brain’s control of digestion, and possibly through a direct effect on the stomach, gamma-oryzanol may help to ease heartburn and other digestive-system discomforts. Ulcer sufferers have taken it with some success. Gamma-oryzanol supplements have also relieved pain, nausea, vomiting, and other post-meal gastrointestinal symptoms in study participants suffering from gastritis (stomach inflammation). Japanese scientists conducting various trials have discovered that gamma-oryzanol may ease hot flashes and other symptoms of menopause, and may even help to lower cholesterol. In addition, antioxidant properties in the extract may protect heart vessels from free-radical damage.

Body-builders have tried gamma-oryzanol supplements to boost their performance, but clinical trials indicate that this is fruitless. In a 1997 study, male weight trainers who took gamma-oryzanol supplements (500 mg a day for nine weeks) failed to perform better than participants taking a placebo. Nor were levels of various hormones, including endorphins or testosterone (a male hormone), affected in any way.

General Interaction

There are no known drug or nutrient interactions associated with gamma-oryzanol.

Cautions

Gamma-oryzanol appears to be quite safe and free of significant side effects, although more reseach in humans is needed.

People with an underactive thyroid should be aware that gamma-oryzanol can lower levels of thyroid stimulating hormone (TSH) as well as alter test results used to monitor this condition.

Because of its apparent effect on hormone levels, pregnant or breast-feeding women should avoid taking gamma-oryzanol in highly concentrated supplement form.

Ailments-Dosage

Heartburn 150 mg 3 times a day
Ulcers 150 mg 3 times a day for one month

  • Ten Drugs Doctors Should Consider De-Prescribing

    Physicians use the word polypharmacy when a patient is taking five or more prescription drugs daily. A recent survey showed that half of women Medicare recipients were taking five or more drugs daily, and 12% of them were taking ten (!) or more. New patients frequently arrive at WholeHealth Chicago carrying bags stuffed like piñatas with prescription drugs and nutritional supplements, the latter recommended by Read More

  • Toxic Metals, Heart Disease, and Chelation Therapy

    In last week’s Health Tip I reviewed the well-researched health dangers of environmental toxic metals (also called heavy metals). They’ve always been a serious health risk, but with the Trump Administration’s recent rollbacks of clean air and water regulations we can expect even more trouble ahead. Statisticians predict an astonishing 160,000 unnecessary deaths over the next decade from the reversals of clean air and water Read More

  • Heavy Metal Toxicity and Your Health

    For those who were otherwise preoccupied that day long ago in high school chemistry, the heavy metals refer to a group of especially dense metals or metal-like substances (called metalloids) found in the environment. These metals–specifically lead, mercury, arsenic, cadmium, and aluminum–can all be absorbed by your body and stored there. Our environment is already quite toxic (Trump’s EPA deregulations aren’t helping) and it’s getting Read More
