  • Unmasking black pepper's secrets as a fat fighter - Science Daily, 5/2/12 - "piperine also can block the formation of new fat cells ... piperine interferes with the activity of genes that control the formation of new fat cells. In doing so, piperine may also set off a metabolic chain reaction that helps keep fat in check in other ways"
  • Curcumin and Piperine Prevent Remodeling of Aorta - Medscape, 12/26/11 - "N-nitro-L-arginine-methylester (L-NAME) is a nonspecific inhibitor of all three NO synthase (NOS) isoforms (neuronal - nNOS; inducible - iNOS; endothelial - eNOS) and causes an increase of blood pressure in a dose-dependent manner when administered to the experimental animals ... Administration of piperine or curcumin to animals with L-NAME-induced hypertension lead to a decrease of blood pressure, curcumin causing a more significant drop. Similar hypertension reducing effect of curcumin has been reported recently by Nakmreong et al.[34] Another study[25] registered a significant decrease of blood pressure after intravenous piperine administration. Piperine treatment was effective also in lowering blood pressure in rats with L-NAME-induced experimental hypertension described by Kumar et al.[36] The combination of curcumin and piperine in our experiment did not cause a statistically significant blood pressure decrease (with the exception of the third week) but it is apparent that it copies the course of the piperine graph curve. These differences in the results are probably related to different mechanisms of effect by the spices on blood pressure"
  • The Doctor's Remedy: Turmeric for Joint Pain - NYTimes.com, 10/19/11 - "Physician: Dr. Minerva Santos, director of integrative medicine at Northern Westchester Hospital in New York ... Recommended Remedy: Turmeric for joint pain ... What the Doctor Says: ... She recommends a dose of 1,000 milligrams a day. The benefit of buying it in a bottle, she said, is that it’s usually combined with a compound called piperine, which aids absorption"
  • Resveratrol bioavailability boosted by piperine: Study - Nutra USA, 8/16/11 - "Using mice, Prof Ahmad and his co-workers analyzed the level of exposure and maximum blood levels of resveratrol achieved by combining 100 milligrams of resveratrol per kilogram of animal with 10 mg/kg of piperine ... Compared to resveratrol alone, combination with piperine was found to increase the degree of exposure to 229 percent, and the maximum levels in the blood by a whopping 1,544 percent" - [Abstract] - See resveratrol products at Amazon.com.
  • Spices may boost breast health: Study - Nutra USA, 12/9/09 - "curcumin, found in turmeric, and piperine, found in black peppers, decreased the number of stem cells while having no effect on normal differentiated cells ... If we can limit the number of stem cells, we can limit the number of cells with potential to form tumours ... normal, non-cancerous stem cells were unaffected by the compounds, which appeared to selectively target the cancer stem cells" - [Abstract]
  • Monthly Updates - Hair Loss Research, 10/01 - "While finasteride (Propecia/Proscar) decreases serum DHT, it also is thought to increase estrogen which suggests that men over 35 may want to consider using it in conjunction with a systemic aromatase inhibitor such as Chrysin/Piperine (Super Miraforte), Arimidex, or stinging nettle extract, to maximize its hair growth effects and minimize potential side effects (that are listed in the PDR) such as Gynocaemastia (breast enlargement in males), sexual side effects, and an increase in fat deposition. These compounds have been reliably shown to increase testosterone and reduce excess estrogen, resulting in a youthful hormone profile that optimizes immune function and to some degree, body composition"


  • Piperine attenuates the inflammation, oxidative stress, and pyroptosis to facilitate recovery from spinal cord injury via autophagy enhancement - Phytother Res 2022 Sep 17 - "Spinal cord injury (SCI) is a serious injury that can lead to irreversible motor dysfunction. Due to its complicated pathogenic mechanism, there are no effective drug treatments. Piperine, a natural active alkaloid extracted from black pepper, has been reported to influence neurogenesis and exert a neuroprotective effect in traumatic brain injury ... Piperine enhanced functional recovery after SCI. Additionally, piperine reduced inflammation, oxidative stress, pyroptosis, and activated autophagy. However, the effects of piperine on functional recovery after SCI were reversed by autophagy inhibition. The study demonstrated that piperine facilitated functional recovery after SCI by inhibiting inflammatory, oxidative stress, and pyroptosis, mediated by the activation of autophagy" - See piperine extract at Amazon.com.
  • Piperine Enhances the Antimalarial Activity of Curcumin in Plasmodium berghei ANKA-Infected Mice: A Novel Approach for Malaria Prophylaxis - Evid Based Complement Alternat Med 2022 Sep 5 - "The delayed onset of clinical symptoms and prolonged survival rate were also significant (p < 0.05) in the combination of curcumin and piperine treated group. In addition, the low parasitic load in the liver and mild histopathological changes in the liver suggest that the combination of curcumin and piperine had synergistic or additive effects. These findings demonstrate the promising use of these combined compounds as a malarial prophylactic" - See piperine extract at Amazon.com and curcumin at Amazon.com.
  • Dietary Piperine Suppresses Obesity-Associated Breast Cancer Growth and Metastasis by Regulating the miR-181c-3p/ PPARα Axis - J Agric Food Chem 2021 Dec 14 - "piperine represents a potential candidate for further development as an anticancer agent for treating obesity-associated breast cancer"
  • Piperine for treating breast cancer: A review of molecular mechanisms, combination with anticancer drugs, and nanosystems - Phytother Res 2021 Sep 24 - "Piperine (PIP) is an alkaloid found primarily in Piper longum, and this natural compound has been shown to exert effects on proliferation and survival against various types of cancer. In particular, PIP has potent inhibitory effects on breast cancer (BC), the most prevalent type of cancer in women worldwide. PIP targets numerous signaling pathways associated with the therapy of BC cells through the following mechanisms: (a) induction of arrest of the cell cycle and apoptosis; (b) alteration of the signaling protein expression; (c) reduction in transcription factors; and (d) inhibition of tumor growth. BC cells have the ability to resist conventional drugs, so one of the strategies is the combination of PIP with other phytochemicals such as paclitaxel, thymoquinone, hesperidin, bee venom, tamoxifen, mitoxantrone, piperlongumin, and curcumin"

  • Iron and Physical Activity: Bioavailability Enhancers, Properties of Black Pepper (Bioperine ®) and Potential Applications - Nutrients 2020 Jun 24 - "Black pepper (Piper nigrum L.) has been employed in medicine (epilepsy, headaches, and diabetes), where its effects are mainly attributed to a nitrogen alkaloid called piperidine (1-(1-[1,3-benzodioxol-5-yl]-1-oxo-2,4 pentenyl) piperidine). Piperine co-administered with vitamins and minerals has improved its absorption ... athletes have risk factors for Fe depletion, Fe deficiency, and eventually, anemia, mainly from mechanical hemolysis, gastrointestinal disturbances, and loss of Fe through excessive sweating. Declines in Fe stores have been reported to negatively alter physical capacities such as aerobic capacity, strength, and skeletal muscle recovery in elite athletes. Thus, there is a need to maintain Fe storage, even if Fe intake meets the recommended daily allowance (RDA), and Fe supplementation may be justified in physically active individuals, in states of Fe deficiency, with or without anemia. Females, in particular, should monitor their Fe hematological profile. The recommended oral Fe supplements are ferrous or ferric salts, sulfate, fumarate, and gluconate. These preparations constitute the first line of treatment; however, the high doses administered have gastrointestinal side effects that reduce tolerance and adherence to treatment. Thus, a strategy to counteract these adverse effects is to improve the bioavailability of Fe. Therefore, piperine may benefit the absorption of Fe through its bioavailability enhancement properties. Three research studies of Fe associated with black pepper have reported improvements in parameters related to the metabolism of Fe, without adverse effects"
  • Curcuminoids plus piperine improve nonalcoholic fatty liver disease: A clinical trial - J Cell Biochem. 2019 Sep;120(9):15989-15996 - "Supplementation with curcuminoids plus piperine significantly reduced the hematocrit (P = 0.027), erythrocyte sedimentation rate (P = 0.048) and the serum concentrations of alanine aminotransferase (P = 0.035), aspartate aminotransferase (P = 0.042), alkaline phosphatase (P = 0.004), cholesterol (P < 0.016), low-density lipoprotein cholesterol (P < 0.017), Iron (P = 0.026), and Hemoglobin (P = 0.025) and increased total iron-binding capacity (P = 0.003).
