Turmeric may be the most effective nutritional supplement in existence.Many high-quality studies show that it has major benefits for your body and brain.Here are the top 10 evidence-based health benefits of turmeric.
Turmeric Contains Bioactive Compounds With Powerful Medicinal Properties
Turmeric is the spice that gives curry its yellow color. It has been used in India for thousands of years as a spice and medicinal herb. Recently, science has started to back up what Indians have known for a long time — it really does contain compounds with medicinal properties (1). These compounds are called curcuminoids, the most important of which is curcumin. Curcumin is the main active ingredient in turmeric. It has powerful anti-inflammatory effects and is a very strong antioxidant. However, the curcumin content of turmeric is not that high. It’s around 3%, by weight (2). Most of the studies on this herb are using turmeric extracts that contain mostly curcumin itself, with dosages usually exceeding 1 gram per day. It would be very difficult to reach these levels just using the turmeric spice in your foods. Therefore, if you want to experience the full effects, you need to take a supplement that contains significant amounts of curcumin. Unfortunately, curcumin is poorly absorbed into the bloodstream. It helps to consume black pepper with it, which contains piperine, a natural substance that enhances the absorption of curcumin by 2,000% (3). The best curcumin supplements contain piperine, substantially increasing their effectiveness. Curcumin is also fat soluble, so it may be a good idea to take it with a fatty meal.
Curcumin Is a Natural Anti-Inflammatory Compound
It helps your body fight foreign invaders and also has a role in repairing damage. Without inflammation, pathogens like bacteria could easily take over your body and kill you. Although acute, short-term inflammation is beneficial, it can become a major problem when it becomes chronic and inappropriately attacks your body's own tissues. Scientists now believe that chronic, low-level inflammation plays a major role in almost every chronic, Western disease. This includes heart disease, cancer, metabolic syndrome, Alzheimer's and various degenerative conditions (4, 5, 6). Therefore, anything that can help fight chronic inflammation is of potential importance in preventing and even treating these diseases. Curcumin is strongly anti-inflammatory. In fact, it’s so powerful that it matches the effectiveness of some anti-inflammatory drugs, without the side effects (7, 8, 9 ). It blocks NF-kB, a molecule that travels into the nuclei of your cells and turns on genes related to inflammation. NF-kB is believed to play a major role in many chronic diseases (10, 11). Without getting into the details (inflammation is extremely complicated), the key takeaway is that curcumin is a bioactive substance that fights inflammation at the molecular level (12, 13, 14).
4. Curcumin Boosts Brain-Derived Neurotrophic Factor, Linked to Improved Brain Function and a Lower Risk of Brain Diseases.Back in the day, it was believed that neurons weren't able to divide and multiply after early childhood.
However, it’s now known that this does happen. Neurons are capable of forming new connections, but in certain areas of the brain they can also multiply and increase in number. One of the main drivers of this process is brain-derived neurotrophic factor (BDNF), which is a type of growth hormone that functions in your brain (20). Many common brain disorders have been linked to decreased levels of this hormone, including depression and Alzheimer's disease (21, 22). Interestingly, curcumin can increase brain levels of BDNF (23, 24). By doing this, it may be effective in delaying or even reversing many brain diseases and age-related decreases in brain function (25). It may also improve memory and make you smarter, which seems logical given its effects on BDNF levels. However, controlled studies in people are needed to confirm this (26).
Turmeric Can Help Prevent (And Perhaps Even Treat) Cancer
Cancer is a terrible disease, characterized by uncontrolled cell growth. There are many different forms of cancer, which still have several things in common. Some of them appear to be affected by curcumin supplements (33). Curcumin has been studied as a beneficial herb in cancer treatment and been found to affect cancer growth, development and spread at the molecular level (34). Studies have shown that it can contribute to the death of cancerous cells and reduce angiogenesis (growth of new blood vessels in tumors) and metastasis (spread of cancer) (35). Multiple studies indicate that curcumin can reduce the growth of cancerous cells in the laboratory and inhibit the growth of tumors in test animals (36, 37). Whether high-dose curcumin (preferably with an absorption enhancer like piperine) can help treat cancer in humans has yet to be studied properly. However, there is evidence that it may prevent cancer from occurring in the first place, especially cancers of the digestive system like colorectal cancer. In a 30-day study in 44 men with lesions in the colon that sometimes turn cancerous, 4 grams of curcumin per day reduced the number of lesions by 40% (38). Maybe curcumin will be used along with conventional cancer treatment one day. It's too early to say for sure, but it looks promising and is being intensively studied.
OCD (Obsessive Compulsive Disorder)
9. Studies Show That Curcumin Has Incredible Benefits Against Depression
Curcumin has shown some promise in treating depression. In a controlled trial, 60 people with depression were randomized into three groups (45). One group took Prozac, another group one gram of curcumin and the third group both Prozac and curcumin. After 6 weeks, curcumin had led to improvements that were similar to Prozac. The group that took both Prozac and curcumin fared best (45). According to this small study, curcumin is as effective as an antidepressant. Depression is also linked to reduced levels of brain-derived neurotrophic factor (BNDF) and a shrinking hippocampus, a brain area with a role in learning and memory. Curcumin boosts BNDF levels, potentially reversing some of these changes (46). There is also some evidence that curcumin can boost the brain neurotransmitters serotonin and dopamine.
Curcumin May Help Delay Aging and Fight Age-Related Chronic Diseases
If curcumin can really help prevent heart disease, cancer and Alzheimer's, it would have obvious benefits for longevity. For this reason, curcumin has become very popular as an anti-aging supplement (49). But given that oxidation and inflammation are believed to play a role in aging, curcumin may have effects that go way beyond just preventing disease (50).
Turmeric and especially its most active compound curcumin have many scientifically-proven health benefits, such as the potential to prevent heart disease, Alzheimer’s and cancer. It’s a potent anti-inflammatory and antioxidant and may also help improve symptoms of depression and arthritis. If you want to buy a turmeric/curcumin supplement, there is an excellent selection on Amazon with thousands of great customer reviews. It’s recommended to find a product with BioPerine (the trademarked name for piperine), which is the substance that enhances curcumin absorption by 2,000%. Without this substance, most of the curcumin just passes through your digestive tract. Healthline and our partners may receive a portion of the revenues if you make a purchase using a link above.
