TURMERIC VS. CURCUMIN: WHAT'S THE DIFFERENCE AND WHICH IS BETTER FOR YOU?
Medically reviewed by Sohaib Imtiaz, MD
Turmeric and curcumin are known for their anti-inflammatory and antioxidant effects. They may help support brain, heart, joint, and digestive health. While the two are closely related, each offers unique benefits.
Turmeric is a golden-yellow spice that comes from the rhizome (root) of the Curcuma longa plant. It has been used for thousands of years in South Asian cuisine and traditional Chinese and Ayurvedic medicine. Curcumin is the main active compound in turmeric. It gives turmeric its color and is responsible for many possible health benefits.
Turmeric vs. Curcumin: What's the Difference?
Turmeric is a whole root that is often dried and ground into a spice. Curcumin is the main active compound in turmeric. Below are some other key differences between turmeric and curcumin.
Turmeric
Available in the spice aisle or as a fresh root in grocery stores and markets
Contains over 200 natural compounds, including curcuminoids (like curcumin), polyphenols, and antioxidants
Provides small amounts of fiber, minerals, and other plant-based nutrients
Curcumin
Responsible for many of turmeric's anti-inflammatory and antioxidant properties
The most studied component of turmeric, despite making up only 2% to 9% of turmeric by weight
Often extracted and concentrated into supplements that may reduce inflammation, support joint and heart health, and promote overall wellness
Health Benefits of Turmeric
1. Anti-Inflammatory and Antioxidant Properties
Whole turmeric contains antioxidant compounds that fight inflammation and neutralize harmful molecules known as free radicals. Antioxidants can help protect cells from oxidative stress, which is an imbalance of free radicals and antioxidants that can lead to cell damage. Antioxidants can possibly lower the risk of inflammation and chronic disease, including cancer, heart disease, and metabolic disorders.
2. Digestive Support
Turmeric helps stimulate bile production in the gallbladder, which promotes fat digestion. Many people add turmeric to fiber-rich foods, such as beans, to aid digestion and relieve digestive discomfort, such as gas and bloating.
3. Skin Health
Applying turmeric topically (to the skin) or regularly adding turmeric to your meals could improve skin health. Its anti-inflammatory properties can reduce redness and irritation associated with skin conditions like acne, psoriasis, and eczema. Some evidence suggests its antimicrobial properties may protect against skin infections.
4. Cancer-Fighting Effects
In lab and animal studies, turmeric extract was more effective at slowing the growth of certain cancer cells—such as breast and colon cancer—than its active compound, curcumin. Turmeric contains many natural plant compounds that work together to enhance its cancer-fighting effects.
While these findings are promising, most research has been done in test tubes or animals, and more human studies are needed to confirm whether turmeric or curcumin can help fight cancer.
Health Benefits of Curcumin
1. Joint Health
Curcumin's anti-inflammatory properties may help reduce joint pain and swelling in people with arthritis. Research studies exploring its effects on joint health show curcumin supplementation relieves joint pain as effectively as nonsteroidal anti-inflammatory drugs (NSAIDs) such as Advil (ibuprofen) and Aleve (naproxen), especially in people with osteoarthritis and rheumatoid arthritis.
In a study exploring curcumin's effects in people with knee osteoarthritis, study participants who were given curcumin supplements reported improvements in knee joint mobility and function.
2. Heart Health
Curcumin may support heart health and lower the risk of heart disease by managing several risk factors, including chronic inflammation, high cholesterol, and metabolic conditions like type 2 diabetes.
Research suggests curcumin may benefit the endothelium—the thin layer of cells lining the heart and blood vessels. Endothelial dysfunction increases the risk of high blood pressure (hypertension), blood clots, and other cardiovascular issues. Curcumin may help support healthy endothelial function, protecting blood vessels and improving blood flow.
3. Mood and Memory
Studies suggest curcumin may increase brain-derived neurotrophic factor (BDNF) levels, a protein that helps support brain cell growth and is linked to better memory and learning.
Low BDNF levels are associated with a higher risk of mood disorders and age-related cognitive decline. In one study involving older adults, curcumin supplementation improved working memory and mood and reduced fatigue.
Some research suggests that curcumin supplements may help reduce depression and anxiety symptoms.
4. Balance Blood Sugar Levels
Curcumin may help regulate blood sugar levels and improve the body's response to insulin, especially in people with type 2 diabetes or prediabetes. It may also reduce inflammation and oxidative stress, affecting how the body uses and stores glucose.
Some studies suggest curcumin may help lower fasting blood sugar levels after not eating for several hours. It may also reduce hemoglobin A1c levels, which reflect your average blood sugar over two to three months.
These improvements could support better long-term blood sugar control, but more research is needed to confirm the full effects of curcumin over time.
Which Has Better Absorption and Bioavailability?
How well your body absorbs and uses turmeric and curcumin depends on how it's consumed. On its own, curcumin is not easily absorbed, which limits how much your body can use. This is why many curcumin supplements are formulated with ingredients that boost absorption, such as:
- Black pepper extract (piperine): Increases curcumin absorption by up to 2,000%
- Fat-based formulations: Help curcumin dissolve and pass through the digestive system more easily
- Nano-curcumin or liposomal curcumin: Smaller particles of curcumin that are easier for the body to absorb
Whole turmeric contains natural oils that may slightly enhance curcumin absorption, but only a small amount of curcumin. When using turmeric in food, combining it with a source of fat (like oil or coconut milk) or black pepper can help improve its absorption.
Consuming whole turmeric may enhance curcumin's absorption and effectiveness due to the synergistic effects of its natural compounds.
In one study, people were given the same amount of curcumin from three sources: pure curcumin powder, turmeric powder, and freshly grated turmeric—each served with mashed potatoes and cream. Blood levels of curcuminoids were significantly higher after consuming turmeric powder and fresh turmeric compared to curcumin alone, with turmeric powder producing the highest levels.
How to Use
Turmeric
Turmeric is a common ingredient in curries, soups, and stews. You can also enjoy it in teas or drinks like golden milk. In addition to adding flavor and color, regular turmeric consumption may support your overall health. A daily intake of 4,000 to 8,000 milligrams (mg) of turmeric is generally considered safe.
Curcumin
Curcumin is available in supplement form, typically as capsules or powders. These supplements often include piperine (from black pepper) or fat-based carriers to enhance absorption. Because curcumin is fat-soluble, it's best taken with a meal that contains healthy fats to improve how well your body absorbs it. While there's no official recommended daily dose, typical curcumin supplement doses range from 500 to 2,000 mg daily.
Always follow the dosage instructions on the product label and speak with a healthcare provider before starting any new supplement, especially if you have a health condition or take prescription medications.
Side Effects and Safety Considerations
Turmeric and curcumin are generally considered safe and well-tolerated. Some people may experience side effects, such as:
- Abdominal pain
- Diarrhea
- Headaches
- Nausea
Turmeric and curcumin supplements may interact with certain medications, including:
- Blood pressure medications
- Blood thinners (anticoagulants)
- Chemotherapy drugs
- Diabetes medications
Turmeric and curcumin may also increase the risk of bleeding in people who are scheduled for surgery or have bleeding disorders.
Pregnant or breastfeeding people should talk with a healthcare provider before using turmeric or curcumin supplements. While turmeric as a food is considered safe during pregnancy, there is not enough research to determine whether high-dose supplements are safe for a developing fetus.
Turmeric or Curcumin: Which Should You Choose?
Turmeric is a good choice if you want overall support, enjoy using herbs in your cooking, or want a gentle, whole-food option.
Curcumin supplements may offer more substantial targeted benefits if you have specific health concerns, such as joint pain, metabolic issues, or chronic inflammation. They provide a concentrated dose of the most active compound in turmeric and are often formulated for better absorption.
Summary
Turmeric is the whole spice containing many plant compounds; curcumin is the main active compound within turmeric. Both have anti-inflammatory and antioxidant effects that may offer health benefits.
Whole turmeric provides a broad spectrum of natural compounds that work together and is excellent for general wellness and culinary uses. Curcumin supplements deliver a concentrated dose of the most active compound and may be better for addressing specific health concerns like reducing joint pain or supporting heart health.
