Turmeric & Curcumin

Curcumin seed extract

Curcumin is a powerful anti-inflammatory and antioxidant agent with many beneficial effects. Curcumin is an ingredient of turmeric which is a bright yellow spice used to add color and flavor to curry and other Indian dishes, mustard and more. Researchers have been looking at curcumin for some time, but because it only makes up about 2-5% of turmeric some researchers have been looking at the other components of turmeric.

Vision health. A 2016 study found that curcumin stops blood vessel leakage.1 It has anti-inflammatory2 and antioxidant properties.3 It has been shown to help protect retinal pigment epithelial cells against oxidative stress, which can be increased by chronic inflammation.

General health. Curcumin has been found to have blood-sugar-lowering properties related to diabetes5 and supports pancreatic function by encouraging pancreatic islet health.4 Animal research has found that combined with resveratrol curcumin may be helpful in fighting lung cancer.6 It has the potential to also combat depression, and neurodegenerative disease and is also used in detecting Alzheimers because it becomes fluorescent when in contact with beta-amyloid.

Turmeric has a number of traditional uses for conditions such as digestion, blood disorders, infections, gynecological problems, and may be helpful for joint arthritis.7

Important Note:  Before taking turmeric supplements check with your doctor if you are taking a blood thinner.  While adding a bit of turmeric to your cooking is usually ok, more concentrated forms have a lot of punch.  Curcumin, the active ingredient of turmeric is a blood thinner.
