What are the Benefits of Turmeric?

A Plant from India

Turmeric (Curcuma longa), is a plant originating from India where it is widely used in cooking and Ayurvedic medicine. Today, it is mainly known for its rhizome, consumed as food or spice. It is characterized by its beautiful yellow-orange color and warm, peppery taste.

But the turmeric rhizome is also part of superfoods. Indeed, it possesses exceptional nutritional values and beneficial properties for health.

It contains proteins, polyunsaturated fatty acids, vitamins (C, B3, B6, K), minerals and trace elements (calcium, iron, magnesium, phosphorus, potassium…) and natural antioxidants including the famous curcumin.

Turmeric is now available as a dietary supplement, in capsule, tablet, or powder form. It is a good way to take advantage of its numerous benefits for the body.

An Anti-inflammatory, Antioxidant, and Detox Action

In traditional Indian medicine, turmeric is indicated to reduce inflammation. Recent studies also recognize its powerful antioxidant and detoxifying action.

A large part of the benefits of turmeric is due to its orange-yellow pigment called curcumin. Curcumin can regulate inflammatory responses and inhibit molecules involved in inflammation as demonstrated in this study. Furthermore, it protects the body by neutralizing free radicals.

As for the detox action of turmeric, which eliminates toxins and cleanses the liver, it is triggered by stimulating bile production. This bile carries a large portion of the body’s waste. By activating its production, turmeric facilitates the transport and elimination of toxins.

Where to buy turmeric?

Many brands, specialty stores, and online shops offer turmeric. We have reviewed the market and the main resellers for you.

Organic stores

Turmeric is often available in organic stores such as Naturalia, Biocoop, Bio c’bon, or La Vie Claire. It can be found in capsule form or as a powder.

Pharmacies and parapharmacies

Pharmacies and parapharmacies that have a phytotherapy section offer turmeric in capsules, tablets, or combined with other plants. Among the product range of the Arkopharma brand, available in pharmacies, you can find a joint complex of turmeric/harpagophytum/piperine.

Specialized physical stores

Turmeric being very popular, you can find it in herbal and dietary supplement shops. It is also possible to purchase it in large retail stores, diet product stores, or herbalist shops. These generally offer whole or sliced rhizomes.

Finally, turmeric is an essential spice in Indian grocery stores. You will find fresh rhizomes or turmeric powder there.

Online stores and specialized e-commerce

If you want organic turmeric, visit online organic stores (Greenweez, Naturalia, La Fourche…) or dietary supplement and/or superfood retailers (Natura Force, Anastore, Vegalia,…).

Finally, some specialized laboratories in dietary supplements, such as Nutrimea or Nutri&Co, also offer turmeric in capsules.

In what form?

Fresh rhizomes

Fresh rhizomes are perfect for making turmeric recipes or preparing infusions. More aromatic than powder, they have a flavorful, warm, and spicy taste. They have not undergone any transformation and have thus retained all their nutritional values.

In capsules and tablets

Capsule or tablet form is the easiest to find. Tasteless, it is also practical and quick to take. You can even take your capsules with you while traveling.

There are also standardized concentrated extracts that offer a curcumin content of up to 95%.

In powder form

Turmeric powder is used as a spice. You can incorporate it into many dishes as well as in your smoothies and health drinks.

Due to its anti-inflammatory and antioxidant action, it is also beneficial for skin care.

Applied to hair, turmeric powder purifies the scalp, stimulates growth, and brings beautiful luminous highlights.

What criteria should be considered?

The form is not the only criterion to consider when choosing your turmeric. You should also check the elements below.

1. Curcumin concentration

Curcumin being the main active compound of turmeric, a dietary supplement low in curcumin will have less impact on the body.

The concentration of curcumin differs depending on the form of the dietary supplement. Thus, the best turmeric powders have a high curcumin content of 5%. Concentrates and standardized extracts, meanwhile, contain between 90 and 95% curcumin.

This difference in concentration affects the recommended dosage per day. To make the most of turmeric’s properties, you will need to consume 3 g of powder/day compared to 1.2 to 1.7 g with a turmeric extract high in curcumin.

2. Bioavailability of curcumin

The pure form of curcumin is not easily absorbed, and only a small portion reaches the bloodstream. To address this issue, turmeric capsules often contain piperine. Found notably in pepper, it helps to improve the bioavailability of curcumin (that is, its absorption by the body) by up to 2000%, as shown in this study.

You can also opt for olive or coconut oil, which not only pairs well with the taste of turmeric but also enhances the bioavailability of curcumin.

Finally, only free or bioactive curcumin is capable of crossing the blood-brain barrier situated between the bloodstream and the central nervous system. Thanks to a microencapsulation process, curcumin is protected and does not associate with other molecules during its journey in the body: it remains free and more active.

This is why it’s beneficial to choose turmeric associated with piperine and containing free curcumin.

3. Cultivation Method

Turmeric grown using conventional agriculture may contain pesticide residues. We therefore recommend choosing organic quality turmeric, cultivated without chemicals, non-irradiated, and non-GMO.

4. Composition

If you decide to buy turmeric capsules or powder, make sure to check their composition. Some products contain excipients, preservatives, and colorings that are controversial.

Also favor vegetarian capsules.

5. Geographic Origin

Although also cultivated in Indonesia, China, Bangladesh, and South America, India remains the world’s largest producer of turmeric. Indian turmeric is renowned for its high quality and curcumin content.

6. Price

The price of turmeric varies depending on its form, quality, and curcumin concentration. Therefore, price differences can be significant from one product to another.

The average observed price for 90 turmeric capsules ranges between €18 and €30. A price below this often indicates capsules with low curcumin concentration.

Turmeric powder is cheaper than capsules: organic powder is available for around €12 per 500 g.

Online herbalists also sell whole or chopped rhizomes for about €7 per 100 g.
