Introduction

Turmeric is a bright yellow-orange spice obtained from the underground stems of the Curcuma Longa plant. Turmeric is native to Southeast Asia and has been used in countries like India, China, and Indonesia for medicinal and culinary purposes for centuries.

Curcumin is the primary bioactive compound found in turmeric¹ which is responsible for its distinctive earthy aroma, flavour and vibrant colour. Turmeric is a potent anti-inflammatory, antimicrobial, antioxidant and potentially anticarcinogenic because of its variety of beneficial bioactive compounds found in it.  

Components of turmeric

Turmeric contains several bioactive compounds, here are some of the main components found in turmeric.

1. Curcuminoids 

• Curcuminoids are a group of polyphenolic compounds found in turmeric.² These are responsible for the characteristic yellow-orange colour of turmeric. Curcuminoids have anti-inflammatory, antioxidant and anti-cancer properties
• Curcumin is a primary bioactive component found in turmeric. It is a potent antioxidant and anti-inflammatory compound and therefore widely studied for its various health benefits in conditions like arthritis, cardiovascular disease, neurodegenerative diseases and cancer

2. Turmerones 

• Turmerones are a group of volatile compounds found in turmeric. They are known for their aromatic properties giving distinctive flavour and aroma to turmeric. They have anti-inflammatory and neuroprotective properties³

3. Turmeric also contains proteins, fibre, and carbohydrates but they are present in smaller amounts.  

What is the role of turmeric in liver health?

Hepatoprotective properties

Turmeric promotes the regeneration and preservation of liver cells.⁴ This helps in the protection and recovery of liver cells from the damage caused by alcohol, drugs, toxins, and other harmful substances. This makes turmeric an excellent hepatoprotective agent.

Prevention of lipid accumulation in the liver

Excess accumulation of fat (lipids) in liver cells leads to fatty liver disease. Lipids are a broad group of organic molecules which includes fats, oils, cholesterol, and other substances.

There are two types of fatty liver disease. Alcoholic fatty liver disease is caused by excessive alcohol consumption and non-alcoholic fatty liver disease. If not treated on time fatty liver disease can lead to serious complications like liver fibrosis, cirrhosis and even liver failure.

Curcumin found in turmeric has been found to interfere with lipid synthesis and promote the breakdown of fatty acids. This helps to prevent excess lipid accumulation in the liver⁵ and thus fatty liver disease.

Antiviral effects

Curcumin found in turmeric acts against viruses like hepatitis B virus (HBV) and hepatitis C virus (HCV), by preventing its replication. This reduces the viral load in the infected liver cells and protects the liver cells.⁶

Prevention of scar tissue formation in liver

In liver fibrosis, there is an excess accumulation of scar tissue (fibrous tissue) in the liver. In the liver collagen and other components of scar tissue are produced mainly by hepatic stellate cells. Turmeric inhibits the activation and growth of these cells which in turn helps to prevent liver fibrosis progression.⁷

Protects from inflammation

In the liver chronic inflammation can lead to diseases like hepatitis, fatty liver disease and liver fibrosis. Turmeric helps to reduce or prevent inflammation by modifying the activities of molecules involved in the generation of inflammatory responses.

Supports detoxification

Turmeric enhances the activity of various enzymes involved in the detoxification process. This increases the functional capacity of the liver to metabolise and eliminate toxins.

Stimulates bile production

Turmeric Stimulates bile production and secretion⁸ which again helps in the excretion of toxins and waste products from the liver.

Maintains gut barrier integrity

Turmeric helps to maintain the gut barrier intact⁹ so toxins and bacteria from the gut are prevented from entering the liver and causing infection or injury.

Promotion of liver regeneration

Turmeric supports liver regeneration after injury or damage by stimulating the growth of liver cells. This helps to restore the structure and function of the liver.

Antioxidant properties

Antioxidants neutralise free radicals. Free radicals are unstable molecules generated in biochemical reactions in the body which cause damage to healthy body cells. Curcumin found in turmeric is a powerful antioxidant. It also helps to enhance the activity of other antioxidant enzymes in the body.

Dosage and safety considerations

If you have any underlying health condition and are taking medications it is essential to consult your health care professional before starting any new health supplement. Below are some general guidelines regarding the dosage of turmeric in various forms.

Turmeric supplements

In supplements, the dosage varies as per the concentration of the turmeric used. Typically, it is 500mg to 2000 mg of curcumin per day in 2 to 3 divided doses.

Turmeric in cooking

About ½ to 1 teaspoon of turmeric powder per day is generally considered a safe amount to consume for healthy adults.

How to increase the absorption of turmeric in the body?

When turmeric is consumed orally, it is not absorbed well by the body. Studies found that If turmeric is taken with piperine (found in black pepper extract), its absorption in the body is increased¹⁰ so choose a formulation where piperine is also added along with turmeric. Another way is to look for the turmeric formulation which is prepared with technologies like liposomal encapsulation so that its absorption in the body is improved.

Potential side effects

Gastrointestinal Issues

If taken in large quantities or for some people turmeric may cause nausea, bloating, gas or diarrhoea. Usually, these symptoms are mild and temporary.

Increased risk of bleeding

Turmeric may increase the risk of bleeding.  People with bleeding disorders or taking medications like warfarin or aspirin should consult a health care professional before taking turmeric supplements.

Allergic reactions

Although rare, in some individuals turmeric can cause allergic reactions like rash, itching, swelling, and breathing difficulty. In such events discontinue use and seek medical advice.

Gallbladder issues

Turmeric may stimulate the production of bile so people with gallbladder disease or gallstones should take medical advice before taking turmeric supplements as it may worsen the symptoms.

Pregnancy and breastfeeding

Pregnant or breastfeeding women should consult healthcare professionals before using turmeric supplements because there is limited research on the safety of the use of turmeric during pregnancy and breastfeeding.

Drug interactions of turmeric

Turmeric, particularly its active compound curcumin, may interact with certain medications due to its potential effects on various biological processes in the body. Here are some common drug interactions to be aware of when taking turmeric supplements.

Blood thinners

Patients taking blood-thinning medications like warfarin, and aspirin need to consult their healthcare provider before consuming turmeric supplements as it may increase the risk of bleeding.

Nonsteroidal anti-inflammatory drugs (NSAIDs)

Turmeric may increase the risk of gastrointestinal bleeding or ulcers if taken along with Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) which are normally taken for pain relief.

Antidiabetic medications

Turmeric may lower blood sugar levels, so patients with diabetes should monitor their blood sugar levels closely when using turmeric supplements.

Antidepressants (SSRIs)

Patients on antidepressants need medical supervision for adding turmeric supplements along with antidepressant medications.
