One of the most talked about supplements around right now is turmeric (active compound curcumin). We all know people who suffer from chronic inflammation of their joints and are taking mouthfuls of ibuprofen and other non steroidal anti-inflammatory drugs (NSAIDs) to medicate their chronic pain. Enter the humble power of turmeric—curcuma longa is the scientific name. This ancient plant has been used in food and Ayurvedic medicine for thousands of years. Turmeric is a rhizome (subterranean main stem) of the same family as ginger. The plant itself grows to over 3 feet tall, but it’s the stuff in the ground that has garnered so much attention over the years. 

The distinctive yellow-gold color of turmeric comes from it’s main ingredient curcumin. Curcuminoids are also the compounds of turmeric that have been most widely studied in the scientific literature. It’s these compounds that have been reported to have anti-inflammatory, anti-cancer, anti-diabetic effects and even may modulate the effects of Alzheimer’s.

Turmeric is variably absorbed through the GI tract depending how it is eaten. The concentration of turmeric curcumin is improved by adding black pepper. The piperine is the active ingredient in black pepper which inhibits the metabolism of curcumin in the liver boosting the available amount in the blood (bioavailability) 2000% higher than without black pepper. Also, the natural oils found in the turmeric root enhance the bioavailability by 8 times. So eating the whole turmeric root or powdered turmeric with black pepper enhances the effect significantly.

 Turmeric's Anti-inflammatory Benefits

This is the one that seems to ring true with my patients. Every one seems to have some degree of back pain, knee pain or other joint issue. Osteoarthritis is an inflammatory condition characterized by loss of cartilage in the joint. There have been head-to-head trials of NSAIDs (non-steroidal, anti-inflammatory drugs) such as ibuprofen (Advil), naprosyn (Alleve), meloxicam, etc. compared to turmeric supplements in patients with osteoarthritis1 and rheumatoid arthritis2 showing that the patients who took turmeric had similar reduction in pain and without all of the bad side-effects of NSAIDs such stomach ulcers, worsening hypertension, or possible increased risk of stroke and heart attacks that comes with NSAIDs.

Cancer Prevention

Curcumin has been shown to have anti-neoplastic effects on cancer in both cellular and animal studies. According to researchers, curcumin has been shown to slow the growth of several different cancers such as pancreatic, esophageal, prostate, liver and multiple myeloma.3  Studies are currently ongoing to assess the efficacy in humans but there is little debate in the literature that eating foods high in turmeric is beneficial in the overall armamentarium for cancer prevention.

Turmeric for the Treatment of Diabetes

A double-blind, placebo controlled trial looked at patients with pre-diabetes and followed them for development of type II diabetes. Of those in the standard care group, 16% went on to get type II diabetes, whereas NO ONE in the turmeric group progressed on to diabetes.4
