Beta Glucans

How does Beta Glucans work?

Beta glucans might lower blood cholesterol by preventing the absorption of cholesterol from food in the stomach and intestines, when it is taken by mouth. When given by injection, beta glucans might stimulate the immune system by increasing chemicals which prevent infections.

Are there safety concerns?

Beta glucans may be safe for most adults when taken by mouth or when the injectable solution is used for a short time period. Injections which have microparticles are not safe. There isn't enough information to know whether beta glucans are safe when applied to the skin.

The potential side effects of beta glucans, when taken by mouth, are not known. When used by injection, beta glucans can cause chills, fever, pain at the injection site, headache, back and joint pain, nausea, vomiting, diarrhea, dizziness, high or low blood pressure, flushing, rashes, decreased number of white blood cells, and increased urine. People with AIDS who take beta glucans have developed thickening of the skin of the hands and feet.

Do not take more than 15 grams per day by mouth and do not use it for longer than 8 weeks.

Do not use beta glucans if:
  • You are pregnant or breast-feeding.
