Sources & What to Look For
Black pepper is a common spice used in cooking to enhance flavor. It contains piperine, an alkaloid that functions as an antioxidant. Research has explored the health benefits of combining piperine with a curcumin supplement. Some studies show it improves liver health, lowers cholesterol, and helps with glucose control, although further research is needed.
Pepper comes from the peppercorn, a dried unripe fruit. Peppercorns are picked when almost ripe and then allowed to dry until they turn black. One teaspoon of black pepper provides 6 calories and 1 gram (g) of fiber.Piperine is also available in supplement form.
In the United States, the Food and Drug Administration (FDA) does not regulate supplements the way it regulates prescription drugs. That means some supplement products may not contain what the label says. Whenchoosing a supplement, look for independently tested products and consult a healthcare provider, registered dietitian nutritionist (RD or RDN), or pharmacist.
Black pepper is marketed for its anti-inflammatory properties. It is suggested to help with cognitive brain function and gastrointestinal function. It also has antimicrobial and antidepressant properties.
Yet, very few human clinical trials have assessed the outcomes of black pepper as a supplement.
Below are some possible health benefits of black pepper. It should be noted that the studies reviewed mostly use acurcuminsupplement combined with piperine. Curcumin is the active compound found in thespice turmeric. Therefore, it is not certain whether the results are due to one or both compounds.
Additionally, most of the study outcomes focus on laboratory findings and not clinically significant findings like reduced risk of heart attack or secondary complications associated with diabetes.
Therefore, the research is preliminary and not enough to recommend black pepper or piperine supplementation routinely.

May Lower Cholesterol Levels
Studies have looked at whether combining curcumin with piperine may have a role in improving lipid profiles which could prevent heart disease.
A meta-analysis concluded that curcumin and piperine combined significantly reduced total andlow-density lipoprotein (LDL) cholesterol(considered “bad” cholesterol) in people with metabolic syndrome.
Another randomized, double-blinded, placebo-controlled trial evaluated the effects of 500 mg of curcumin capsules with piperine supplement in people with a previous heart attack.
After eight weeks, the supplement significantly reducedhemoglobin A1C, LDL cholesterol, and liver enzymes. It also significantly improved levels ofhigh-density lipoprotein (HDL) cholesterol(considered “good” cholesterol).
Although the results seem promising, the study populations were small, requiring future larger-scale trials to confirm the findings.
May lmprove Glucose Control
Combining curcumin and piperine may help lowerglucose (blood sugar) levelsin people with diabetes. Blood glucose control is important with diabetes to avoid further complications.
Hemoglobin A1c (HbA1c or A1c) levels are measured over a three-month period in people with diabetes to assess the average glucose levels over the previous three months.
In a small study of 71 participants, people were randomized to take either a placebo (an ineffective substance) or a supplement containing 5 mg of piperine and 500 mg of curcumin. After 120 days, those who took the supplement had significantly lower glucose levels, hemoglobin A1C levels, and levels oftriglycerides (a fat in the blood).
In people with type 2 diabetes, a daily dose of 500 mg of curcumin and 5 mg of piperine (compared to placebo) significantly reduced blood glucose, C-peptide, and A1c levels.
The supplement also significantly loweredliver enzymesbut did not affect C-reactive protein levels.
May Improve Liver Health
Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as nonalcoholic fatty liver disease (NAFLD), is a group of conditions with a fatty buildup in the liver. Common causes include obesity, insulin resistance, and diabetes.
A few studies suggest that piperine combined with curcumin as a supplement can improve liver function in people diagnosed with MASLD.
In one study, short-term treatment with curcumin and piperine seemed to reduce the severity of MASLD.
Another study randomized 70 people with MASLD to receive a supplement of 500 mg curcuminoids with 5 mg piperine daily or a placebo for 12 weeks. At the end of the study, those who received the supplement had significantly lower concentrations of liver enzyme blood levels and less severe MASLD.
Another study with a similar regimen in participants diagnosed with hepatic steatosis found that the supplement improved liver function enzymes and lipid profiles. However, it did not improve fibroscan measurements, which are used to assess the improvement of MASLD.
What Are the Side Effects of Black Pepper?
Not many side effects are reported with the use of black pepper.
Higher doses of black pepper may cause a burning sensation in the throat or stomach. It could also contribute to reflux or heartburn.
Black pepper in amounts usually found in food is safe.
Although safe in normal amounts, high doses of black pepper have not been studied for safety in pregnant people, breastfeeding people, or children.
Lab studies have suggested that piperine, the chemical found in pepper, may slow blood-clotting.High doses could lead to bleeding. For this reason, you should discontinue piperine supplements for two weeks before any scheduled surgeries.
People withdiabetesshould monitor their glucose levels closely, as piperine can lower blood glucose levels. Adding piperine could reduce how much medication is needed. People with diabetes should discuss adding supplements to their regimen with their primary care provider to determine if medication dosage adjustments are needed.
Dosage: How Much Black Pepper Should I Take?
There is no standard recommended dose for black pepper.
Studies have shown that doses of piperine often range from 5 mg to 20 mg per day.Five mg is usually the most common dose used in research studies.
Always speak with a healthcare provider before taking a supplement to ensure that the supplement and dosage are appropriate for your individual needs.
It’s possible for piperine to interact with medications.
Some studies have shown that piperine can reduce blood glucose levels.
Combining medications to lower glucose levels with piperine could theoretically lead tohypoglycemia. People with diabetes should always discuss supplements with their primary care provider or other treating provider before starting them. You may need to monitor your blood glucose levels closely.
Piperine may also slow blood clotting. Combining piperine with anticoagulant medications, such as Jantoven (warfarin), could increase your chances of bruising or bleeding as they have similar effects.
Piperine can slow the breakdown of other medications in the liver, increasing the drug’s effects. This may include:
However, studies on these interactions were done in animals and used higher-than-normal piperine doses.
Piperine could increase how the body absorbs some medications, including:
Theoretically, this could increase the effects and possible side effects of these medications.
It is essential to carefully read the ingredients list and nutrition facts panel of a supplement to know which ingredients and how much of each ingredient is included. Please review the supplement label with your healthcare provider to discuss any potential interactions with foods, other supplements, and medications.

Sources of Black Pepper & What to Look For
Black pepper is available as a spice and is easy to add to foods or use in cooking.
Many different types of pepper are available such as white peppercorns and red pepper flakes. However, the information contained in this article is specific to black pepper.
If you arelooking for supplements, you could find piperine alone, but it is often found as a combination of curcumin and piperine. It may also be added to supplements marketed for inflammation that contain several different ingredients.
Always look for supplements that have been independently tested. This means that the product has been evaluated to ensure that it contains what the label claims and is free of contaminants.
Summary
Black pepper is a common spice added to foods. Piperine, a compound found in pepper, has been studied for health benefits. Preliminary results show that piperine (combined with curcumin) may improve lipid profiles, glucose control, and liver function enzymes.
Further research is needed to determine whether piperine supplementation could lead to a reduced risk of disease.
Discuss your supplement use with a healthcare provider, as many supplements are not recommended in certain conditions and can interact with prescribed medications.
