Turmeric is a popular spice known for its health benefits, but excessive use can lead to side effects. One common issue is digestive discomfort, such as bloating or acid reflux. It may also cause allergic skin reactions in sensitive individuals.
High doses of turmeric supplements have been linked to increased risk of kidney stones due to oxalate content. In rare cases, turmeric can interfere with blood clotting, which is crucial for individuals on blood-thinning medication.
Approximately 2-3% of people report mild headaches after consuming turmeric supplements. Studies also indicate that long-term excessive turmeric consumption can impact liver health, affecting 5-7% of individuals in clinical assessments.
Here are the 10 serious side effects of turmeric you should know especially if you take it in supplement form.
What is Turmeric and Its Uses ?
Turmeric is scientifically known as Curcuma longa, a perennial plant from the Indian subcontinent and Southeast Asia. For centuries it has been a mainstay in traditional medicine, prized for its healing properties.
The yellow color of turmeric comes from its active compound curcumin which is responsible for many of its benefits.
In traditional medicine turmeric is used to treat various conditions like arthritis, digestive problems and skin issues. Its anti-inflammatory and antioxidant properties make it a popular natural remedy.
Beyond its medicinal uses turmeric is a staple in culinary traditions especially in Indian and Middle Eastern cooking where it adds flavor and color to dishes. It’s also used as a natural dye, it’s so versatile.
1. Allergic Contact Dermatitis Reactions to Turmeric
Taking turmeric supplements can cause unexpected allergic reactions. You may experience symptoms from a sudden skin rash or itching to severe cases of anaphylaxis after consuming turmeric powder.
Allergic contact dermatitis which manifests as a rash and itching can occur in those allergic to turmeric. This is a problem for those who use turmeric in topical applications like face masks or creams.
Cross reactivity is another issue. Those allergic to plants like Cocklebur or Mugwort may also react to turmeric as the same immune response is triggered.
As you can see, diagnosing a turmeric allergy involves observing symptoms after exposure and may include skin prick test or blood test. Consult your doctor to determine the root cause of any adverse reaction to turmeric or curcumin.
2. Gastrointestinal Problems
The benefits of turmeric may be overshadowed by the side effects. Turmeric supplements can cause stomach upset and abdominal pain and discomfort which is not what you want when you’re trying to get healthy.
High doses of turmeric can worsen stomach problems and cause nausea and diarrhea. Frequent trips to the bathroom can ruin your day, a common side effect that’s often overlooked when you start taking dietary supplements.
Moreover, large amount of turmeric can also cause acid reflux and worsen the burning sensation in your chest after meals.
Most gastrointestinal side effects occur at higher doses than what’s found in food so a sprinkle of turmeric powder in your curry is probably safe. But high dose curcumin supplements may need to be reevaluated. Ask your doctor first.
3. Liver Injury Risk
Despite its antioxidant properties turmeric can harm liver. It can cause drug induced liver injury especially in those with pre-existing liver condition or those who take high dose. For those with liver disease turmeric may do more harm than good.
Liver related adverse reactions include hepatobiliary disorders or abnormal liver function test results. Elevated liver enzymes like AST and ALT may indicate liver injury from curcumin supplements which usually normalize after stopping the supplement.
Those with bile duct obstruction, cholangitis, liver disease, gallstones or biliary disease should avoid turmeric and curcumin.
4. Blood Thinner Effects
Turmeric’s blood thinner effect is a double edged sword. While it promotes better blood flow and reduces the risk of clot, it also increases the risk of bleeding. Those on blood thinner or have bleeding disorder should reconsider curcumin supplements.
Curcumin’s antiplatelet effect reduces the blood’s ability to clot so be cautious if you’re on blood thinner. Mixing turmeric supplements with blood thinner can increase severe bleeding risk. Inform your doctor before any surgical procedure if you’re taking turmeric.
Cooking with turmeric is generally safe but concentrated dose in supplements can enhance blood thinner effect. So high dose of turmeric may not be suitable for everyone.
Be cautious with turmeric supplements if you have bleeding disorder or on medication that affects blood clotting. Consult your doctor to prevent adverse effects.
5. Gallbladder Complications
Turmeric can also affect your gallbladder. It stimulates bile secretion which is good for digestion but bad for those with gallbladder problems. If you have gallstones or other gallbladder issues turmeric may not be suitable.
Anyway, if you don’t know where the gallbladder is, this guide can help. In what part of your body is the gallbladder?
Curcumin can cause gallbladder contractions which helps in bile expulsion but can trigger biliary colic in those with gallstones.
Unexpected right ?
Of course, those with gallbladder problems should be cautious with curcumin supplements. Avoid turmeric supplements if you have bile duct obstruction.
6. Kidney Concerns
Turmeric’s high oxalate content can harm kidney and contribute to kidney stone formation. If you’re prone to kidney stone turmeric supplements may not be suitable. Reducing dietary oxalate intake is crucial for managing oxalate nephropathy.
Those with kidney problems should be cautious with all supplements including turmeric. Consult your doctor before starting turmeric supplements.
7. Blood Sugar Levels
Curcumin the active ingredient in turmeric lowers blood sugar levels so it’s a potential diabetes treatment but also a risk.
Adding curcumin supplements while on diabetes medication can lead to hypoglycemia.
Curcumin’s blood sugar lowering effect can be beneficial for those with diabetes but the risk of hypoglycemia increases when combined with diabetic treatment so monitoring is required including curcumin maintenance therapy.
8. Cardiovascular Risks
Turmeric’s effect on cardiovascular health is a concern. Some studies suggest that turmeric or curcumin can affect heart rate or rhythm and is a risk for those with cardiovascular disease.
A case study reported a person who experienced atrioventricular heart block while taking turmeric supplement. 7% of reported adverse effects of curcuma are cardiovascular in nature so be cautious especially if you have pre-existing heart condition.
The case study also mentioned that the heart rhythm disturbance returned when the turmeric supplement was restarted after discontinuation so be cautious and consult your doctor before taking turmeric.
For healthy adults cardiovascular risk is minimal but for those with cardiovascular condition be extra cautious.
As mentioned, consult your doctor before adding turmeric supplements to your regimen.
9. Cancer and Neurodegenerative Conditions
Curcumin the active compound in turmeric is being studied for its anti-cancer and neuroprotective properties.
Research shows that curcumin inhibits cancer cell proliferation including LNCaP prostate cancer cells and human breast cancer cells. So it’s a potential cancer prevention and treatment strategy.
Also curcumin has benefits for brain health. Its neuroprotective effects can prevent or slow down neurodegenerative diseases like Alzheimer’s and Parkinson’s. By reducing brain inflammation and oxidative stress curcumin supports brain function and brain health.
10. Hormonal Effects
Turmeric’s estrogenic effects can be a double edged sword. While it has some benefits it’s a risk for those with hormone sensitive condition like breast cancer and endometriosis.
In some situations, curcumin can affect estrogen receptor regulation and is a risk in hormone sensitive cancers. While turmeric may benefit some it can be harmful for those at high risk of hormone related cancers as curcumin inhibits proliferation.
Those at high risk of cancer should be cautious with dietary curcumin supplements.
Other Effects

12. Precautions when taking turmeric supplements
