Turmeric

What is Turmeric?

Turmeric, or Curcuma longa, is a plant belonging to the ginger family and is known for its vibrant yellow roots. It is widely used in cooking, especially in Indian and Asian cuisine, but has also gained significant attention as a dietary supplement due to its potential health benefits. Turmeric contains curcumin, an active compound known for its anti-inflammatory and antioxidant properties. In this article, we will explore turmeric’s functions in the body, scientific benefits, dosage, sources, side effects, and answer common questions.

How does it work in the body?

Curcumin in turmeric works by affecting multiple molecular targets in the body. It has been shown to modulate signalling pathways involved in inflammation and cellular protection. Curcumin can also influence the production of cytokines, which are proteins that play a crucial role in the immune system. By reducing inflammation, turmeric may help alleviate symptoms of various conditions, including joint inflammation and digestive issues.

Scientific benefits

Several studies have investigated the health benefits of curcumin. Here are some of the most prominent findings:

• Anti-inflammatory effects: A study published in The Journal of Alternative and Complementary Medicine demonstrated that curcumin can reduce symptoms of arthritis and joint inflammation.
• Antioxidant properties: Research has shown that curcumin can neutralise free radicals and enhance the body’s antioxidant defences, providing a protective effect on cells.
• Digestive health: A study published in the Journal of Clinical Gastroenterology reported that curcumin may relieve symptoms of irritable bowel syndrome and improve digestion.
• Heart health: Curcumin can improve endothelial function (blood vessel function) and thereby reduce the risk of cardiovascular diseases, according to a review article in the Journal of the American College of Cardiology.

Dosage and recommendations

The recommended dose of turmeric or curcumin can vary depending on individual needs and health conditions. Generally, experts suggest taking between 500 mg to 2000 mg of curcumin per day, divided into several doses. It is important to note that curcumin has low bioavailability, meaning the body does not absorb it efficiently without the aid of substances such as black pepper (piperine) or fat. Many supplements therefore include these ingredients to enhance absorption.

Best sources and forms

Turmeric is available in several forms, including:

• Turmeric powder: The most common way to use turmeric in cooking.
• Dietary supplements: Capsules or tablets containing concentrated doses of curcumin.
• Liquid extracts: A form of turmeric that can be mixed into drinks or smoothies.
• Tea: Turmeric can also be used to make tea, which is an easy way to incorporate it into your diet.

Side effects and warnings

Turmeric is generally considered safe for most people when used in typical dietary amounts. However, at higher doses, some side effects may occur, including:

• Digestive issues such as nausea or diarrhoea.
• Increased risk of bleeding, especially if you are taking blood-thinning medications.
• Allergic reactions, although these are rare.

It is always best to consult a healthcare professional before starting supplements, especially if you have underlying health conditions or if you are pregnant or breastfeeding.
