Complete Guide to Turmeric

What is Turmeric?

Turmeric, a popular spice recognized by its distinct yellow color, is a rhizome or root of the Curcuma longa plant grown primarily in the Indian subcontinent and few Southeast Asian countries.

Did you know that turmeric belongs to the family of ginger, another well-renowned spice?

A common ingredient in traditional Ayurvedic and Chinese medicines, turmeric has been used for more than 4000 years till date to treat a variety of ailments such as inflammation, skin disorders, diabetes, and even cancer (1).

Nutritional Composition

One tablespoon (about 9.4 g) of ground turmeric contains: (2)

  • 29.3 calories
  • 6.31 g – carbohydrates
  • 0.91 g –  protein
  • 0.305 g – fat
  • 2.13 g  – fiber

Apart from the macronutrients, turmeric contains vitamin B6, C, and considerable quantities of minerals such as 196 mg potassium, 28.1 mg phosphorus as well as calcium, iron, manganese, and zinc.

Turmeric is loaded with as many as 100 components. Chief among them are volatile oils such as turmerone and curcuminoids made up of curcumin demethoxycurcumin, 5’-methoxycurcumin, and dihydrocurcumin.

While turmerone oils are responsible for the aromatic nature of turmeric and have significant anti-inflammatory and other pharmacological properties, curcuminoids are effective antioxidants and provide turmeric its vivid yellow color (3), (4).

Besides containing 4 kinds of polysaccharides, turmeric is also rich in omega-3 fatty acids and alpha-linolenic acid with zero cholesterol.

Summary: Turmeric, a rhizome of the Curcuma longa plant has been used in traditional medicine. It contains nearly 100 components including turmerone oils and curcuminoids which are proven to have many medicinal properties.

What is Curcumin?

Curcumin is the champion among turmeric’s many compounds! It makes up a part of the potent curcuminoids and is the contributor to turmeric’s bright yellow color (5).

The presence of curcumin in pure turmeric averages around 3% by weight. Curcumin incurred through daily diet has poor bioavailability and hence may be recommended as supplements in higher concentrations (6).

Extra ingredients such as piperine available in black pepper extracts or healthy fats that support better absorption are common additions in turmeric supplements that provide better bioavailability of curcumin in the body.

Curcumin is the highest researched component of turmeric and various clinical trials have indicated curcumin’s efficiency in treating inflammatory conditions, skin diseases, cardiac conditions, Irritable Bowel Syndrome (IBS), Alzheimer’s, etc.

Summary: Curcumin, one the main curcuminoids in turmeric, may be prescribed in supplement form for better efficiency. Numerous research and clinical trials highlight its benefits in treating various medical conditions.

Turmeric vs Curcumin

Turmeric versus curcumin is a long-debated topic as to which of them is more beneficial. Is turmeric more potent than curcumin? Or, is curcumin responsible for turmeric’s healing properties?

To find the answers, let’s look at the common and individual benefits of turmeric and curcumin.

Benefits Common to Turmeric and Curcumin

Turmeric has many natural components present, but the most active one among them is curcumin. Turmeric as a whole and curcumin have therapeutic properties that help provide several health benefits.

Scientific studies on turmeric and curcumin extracts have shown them to help treat medical conditions such as osteoarthritis, lowering the risk of heart disease by regulating lipid levels, and managing blood sugar levels (7), (8), (9).

Research has also revealed that turmeric and curcumin can protect against liver damage, fight cancer with chemopreventive activity, and exert protective antifungal and antibacterial effects (10), (11), (12), (13).

The Potential Benefits of Curcumin

Curcumin is the most powerful among the many turmeric compounds that have been found to have properties of its own to benefit human health.

Recent studies have revealed that curcumin may be important and effective in the prevention and treatment of diabetes and its associated disorders. While studies on rats have shown that curcumin is more effective in treating diabetes mellitus than turmeric, it is thought to be equally true in humans (14), (15).

Research on curcumin has revealed that curcumin exerts anti-inflammatory effects in treating chronic diseases through the downregulation of inflammatory transcription factors (nuclear factor kappaB), enzymes, and cytokines (16).

A daily dose of 6 g of curcumin when supplemented along with 60 mg piperine 48h before and 48h after exercise-induced muscle damage was shown to enhance muscle recovery after 24 h to 48 h after exercise (17).

The Potential Benefits of Turmeric

Turmeric has displayed significant prowess in treating several medical conditions, along with curcuminoids and several essential oils it possesses.

Turmeric (Curcuma) and it’s extracts containing curcuminoids and oils are considered beneficial in the treatment of age-related disorders such as dementia and may help in treating complications arising due to diabetes mellitus (18).

The anti-inflammatory and antioxidant properties of turmeric may be beneficial in slowing down the brain aging process and lowers the risk of possible neurodegenerative disorders.

Experiments with 8 turmeric compounds (including curdione, isocurcumenol, curcumenol, curzerene, β-elemene, curcumin, germacrone, and curcumol) on 11 fungi revealed that all exhibited antifungal properties but curdione had the highest inhibitory effect (19).

Research also indicates that turmeric, like curcumin, has been shown to suppress inflammation-causing factors such as nuclear factor kappa B (NF-κB), signal transducers, and activators of transcription 3 (STAT3) to inhibit an increase in tumor cells and protect from bone loss (20).

Turmeric or Curcumin: Which One is More Beneficial?

Curcumin and turmeric have shown individual capabilities as well as combined competence in treating several disorders. While curcumin is well researched, turmeric has also shown efficiency with several other compounds.

So if you are asked to choose, the wise option would be to go in for a supplement that contains good quality turmeric extracts but with a higher concentration of curcumin for combined effectiveness and better results.

Summary: Turmeric and curcumin individually and together have shown effectiveness in treating various medical conditions. Turmeric extracts with a higher curcumin percentage may be a better choice to enjoy greater benefits.

Bioavailability of Turmeric

The bioavailability of turmeric and curcumin when obtained through diets is quite low as both quantity and absorption are limited.

For this purpose, many turmeric supplements use ingredients such as black pepper, lecithin, and healthy fats that help enhance the bioavailability of turmeric and its components to the human body.

  • Dietary Fats: Turmeric was a staple in South East cuisines and was included in curries or fatty foods! The reason for this was fat-soluble turmeric used in conjunction with healthy fats increased aroma, flavor, and best of all increased the bioavailability of turmeric to the body (21).
  • Black Pepper: Black pepper can simply spice up your food with an extra zing! Additionally, studies have shown that the piperine in black pepper makes the curcumin 2000% more bioavailable to the body (22).

Black pepper is added to supplements to make turmeric and curcumin more available to the body by inhibiting the quick breakdown of turmeric compounds.

  • Lecithin: Soy lecithin, a plant-based additive, is extracted from soy and used as a food additive in dietary supplements. Research has shown that soy lecithin can enhance the bioavailability of curcumin.

A 2018 study showed that a complex of curcumin and lecithin exerted anti-inflammatory effects similar to curcumin and increased bioavailability of curcumin itself (23).

Summary: Turmeric has low bioavailability when consumed via a daily diet. Turmeric supplements can be taken with fatty meals or using products with ingredients such as black pepper and lecithin that increases the bioavailability.

Dosage for Turmeric

Turmeric has been used as a medicinal aid for ages. Supplementation of turmeric depends on the medical condition for which it is recommended and hence the dosage can vary accordingly.

The World Health Organization (WHO) has identified 0-3 mg/kg of curcuminoids as an acceptable range for use as a food additive. The FDA too has approved turmeric and its compounds to be safe for consumption (24).

Randomized clinical trials have indicated that supplements of turmeric extracts with 1 gram of curcumin taken for 8-12 weeks may have efficiency in reducing pain and inflammatory symptoms of arthritis (25).

So far, no maximum tolerated dose for turmeric has been established, but studies have shown that turmeric with curcumin appears to be safe even at doses of 12,000 mg during a chemopreventive intervention (26).

Another study on overweight subjects with hyperlipidemia showed that 1.4 g of turmeric extracts taken in two divided doses before meals for 90 days helped to significantly lower total cholesterol, LDL, triglycerides, and VLDL values (27).

An 8-week study on the efficiency of black seeds (900 mg) and turmeric (1.5 g) combination per day on males with metabolic syndrome revealed improvement in parameters such as body fat percentage, fasting blood sugar, triglycerides, LDL, C-reactive protein, and increased good HDL (28).

Summary: Dosage of turmeric varies on the medical condition for which it is being used. Various studies highlight the different doses of turmeric used for treating different conditions including arthritis, hyperlipidemia, and cancer.

Best Time to Take Turmeric

So, now that we know that the dosage for turmeric varies according to the health condition for which it is taken, another important question asked is “What is the right time to take a turmeric supplement?”

The benefits of turmeric are best achieved by taking the right doses of the supplement at the appropriate time.

Turmeric supplements work best when taken on an empty stomach to maximize absorption. These supplements can be taken either in the morning or at bedtime for relief from inflammation-related conditions.

Some individuals can experience stomach irritation while taking turmeric supplements. Such people are recommended to take turmeric supplements with meals to avoid discomfort.

Summary: Turmeric supplements taken on an empty stomach increase absorption into the body. It can be consumed with meals to avoid stomach discomfort.

Scientifically Proven Benefits of Turmeric

Turmeric, a simple kitchen spice has been used regularly in cooking and traditional medicine to treat several medical conditions such as inflammation, skin diseases, and viral or bacterial infections for ages.

Modern medicine too as seen in studies acknowledge turmeric’s potent antioxidant and anti-inflammatory properties as a safe and effective method to combat medical disorders such as diabetes, depression, arthritis, and cancer (29).

Though the uses of turmeric are many, listed below are some of the potential benefits of using turmeric.

Turmeric for Immunity

Factors such as an unhealthy lifestyle, medical conditions, environmental pollutants, and self-neglect can destabilize and harm the body’s immune system which helps fight us against germs and other disease-causing microorganisms.

Turmeric, a natural and potent spice was used in Ayurvedic medicines and was an integral part of the Indian way of life. Turmeric was used everywhere – in recipes, homemade herbal concoctions, and as topical applications.

Turmeric milk, a tasty warm beverage prepared using turmeric, milk, pepper, and honey was the go-to solution for getting relief from cold, cough, fever, skin diseases, and for boosting overall immunity.

So how does turmeric boost immunity?

Turmeric helps to fortify the immune system through its immunomodulating properties. Studies on turmeric show that it modulates fighter cells such as T cells, B cells, macrophages, neutrophils, and dendritic cells to protect the body and keep harmful diseases at bay (30).

Even the essential oils extracted from turmeric have displayed antioxidant properties that help prevent oxidative stress, free radical damage, and boost immunity (31).

Summary: Turmeric was used in Ayurvedic medicines and Indian homes to boost immunity. Science has proved that turmeric compounds including the volatile oils, help modulate disease-fighting cells to protect the body.

Turmeric and Anxiety

Stress is a common companion in today’s hectic lifestyles and anxiety is the first response to stress. With time, they spiral out of control to lead to complications such as depression or other mental illness.

Natural stress relievers such as turmeric, green tea, chamomile, and chocolate are being used to relieve anxiety on their own or if severe, in tandem with medications.

So, how does turmeric help in relieving anxiety?

In the Indian sub-continent turmeric is often consumed with warm milk and honey at night to relieve stress and induce sleep. This is considered as a natural preventive measure to avoid the risk of mental disorders.

Turmeric and it’s primary compound curcumin has been studied and found to work as follows:

  • Increased anxiety levels can lead to mood disorders such as depression. Recent trials and studies indicate that people with depressive disorders have elevated inflammation in parts of the brain (32).

Turmeric is well known to possess potent antioxidant and anti-inflammatory properties that have shown to relieve anxiety and improve mood in people with major depression (33).

  • Research suggests that turmeric can act as an excellent anxiety reliever. Turmeric has shown promise and efficiency in acting as an effective stress buster and relieving anxiety and depressive symptoms in both animal and human studies (34), (35).
  • Along with antidepressants, curcumin, when taken with piperine to enhance the bioavailability, displayed enhanced anti-depressant effects with increased levels of serotonin (5-HT) to better manage depression (36).
  • Curcumin has been shown to boost DHA (docosahexaenoic acid) from its precursor ALA (alpha-linolenic acid). The deficiency of DHA can contribute to increased anxiety and other cognitive issues (37).
  • Oxidative stress can trigger anxiety and lead to depressive disorders. Glutathione is an antioxidant found in plants that helps fight against oxidative stress and prevents damage caused by free radicals.

Glutathione reductase 1, a gene involved in antioxidant metabolism, helps control anxiety and depressive symptoms. Studies indicate that curcumin is capable of exerting antioxidant effects by modulating glutathione levels effectively (38).

Summary: Turmeric and its main component curcumin has shown to reduce anxiety and depressive symptoms by using its potent antioxidant and anti-inflammatory properties. It boosts DHA and glutathione levels to reduce free-radical damage and increases serotonin levels in the brain.

Turmeric and Thyroid Function

Turmeric as a medicinal spice is used to treat various medical conditions efficiently.

A common medical condition prevalent among billions of people is of the thyroid gland. The thyroid, a vital part of the endocrine system, releases hormones that regulate metabolic processes in the human body.

Therefore, any discrepancies in the thyroid function can be devastating for health. And the use of turmeric may help alleviate thyroid-related issues. How?

Read on to know how the use of turmeric helps with the thyroid function.

  • Curcumin, one of the active compounds of turmeric has been shown to improve auto-immune diseases such as rheumatoid arthritis, inflammatory bowel disease, etc. by regulating inflammatory cytokines.

Graves’s disease is an autoimmune disease of the thyroid gland and 131-radioiodine has been vastly used to treat this condition. Curcumin seems to exert protective effects against the damage and side-effects caused by the use of 131-radioiodine (39).

  • Thyroiditis refers to inflammation of the thyroid gland. Hashimoto’s disease is a disease of the thyroid characterized by high inflammation. Studies show that curcumin can help in reducing inflammation and slow down or halt such conditions (40), (41).
  • Hyperthyroidism or increased state of thyroid hormones can create multiple health issues. High thyroid levels can disrupt antioxidant levels in the body resulting in increased oxidative stress in the brain.

Curcumin in animal studies has been shown to enhance the level of antioxidant enzymes that reduce oxidative stress in the brain caused by hyperthyroidism (42).

  • Hypothyroidism or deficiency of thyroid hormones results in an increased level of cholesterol and blood lipids that may result in a higher risk of cardiovascular diseases.

Antioxidants present in turmeric extracts along with vitamin C and E supplementation have shown to have a positive impact on the thyroid gland by reduced suppression of T3 and T4 hormone levels and reduced cholesterol levels (43).

  • Goiter is an inflammation of the thyroid gland and is caused by iodine deficiency. Research suggests that the use of turmeric can reduce the risk of goiter effectively (44).
  • Scientific studies also affirm that curcumin can prevent the proliferation of tumor cells and this helps in lowering the risk of thyroid cancer (45).
  • Thyroid hormones have a major influence on brain functions and an imbalance can affect cognitive functioning and increase the risk of mental disorders (46).

Aging is also a factor that can affect thyroid hormones and elevated levels can increase oxidative stress, which in turn increases the risk of neurodegenerative diseases (47).

Curcumin has already shown the capability to reduce oxidative stress and slow down brain cell damage that could prevent the onset or reduce the severity of various neurodegenerative diseases (48).

Summary: Thyroid is a major gland that controls various processes in the body for metabolic health. Imbalances in the thyroid can lead to various health issues. Curcumin as seen in studies has shown to improve symptoms and treat thyroid-related disorders with proven anti-inflammatory and antioxidant effects.
