Turmeric, with the active component curcumin, is both a food and a dietary supplement that may promote a better immune response and blood sugar levels, and may also help you manage some side effects of cancer.

Turmeric and curcumin at a glance

Turmeric, Curcuma longa, is a tropical plant in the ginger family. It is a main ingredient in curry powder and is used frequently as a seasoning in Indian and other South Asian cuisines. Curcumin is the major constituent and the active component in turmeric, but other curcuminoids have also been studied. Both turmeric and curcumin are available as dietary supplements. 

Curcumin is well established for its anti-inflammatory, antioxidant a molecule that can cause a free radical to stabilize and become less reactive; an antioxidant donates an electron to a free radical without making itself unstable, and antimicrobial properties. Curcumin may reduce some side effects such as fatigue, pain, nausea, and vomiting related to cancer treatments and may improve the quality of life for people with cancer. It may also improve your body environment (terrainthe internal conditions of your body, including nutritional status, fitness, blood sugar balance, hormone balance, inflammation and more) to make it less supportive of cancer growth and development, such as by improving blood sugar control and insulin sensitivity.

Curcumin is poorly absorbed by the gastrointestinal (GI) tract into the blood. Getting it to tumors outside the GI tract via the blood has been difficult.1Fajardo AM, Piazza GA. Chemoprevention in gastrointestinal physiology and disease. Anti-inflammatory approaches for colorectal cancer chemoprevention. American Journal of Physiology. Gastrointestinal and Liver Physiology. 2015 Jul 15;309(2):G59-70. Some formulations are designed to increase absorption:

  • A liposomalvery tiny, fat-like particles used as delivery enhancers for some vitamins, minerals, and micronutrients to improve transport into the bloodstream form5Feng T, Wei Y, Lee RJ, Zhao L. Liposomal curcumin and its application in cancer. International Journal of Nanomedicine. 2017 Aug 21;12:6027-6044.

Consuming turmeric with either pepper or fats may also increase absorption.6TRC Natural Medicines. Turmeric. December 14, 2017. Viewed January 15, 2018.
