What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 7 active ingredients.
  • “Resveratrol” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “Flavonoids” is listed as a grouped ingredient — the label gives one combined amount (85 mg) without saying how much of each component you get.
  • “Proprietary Neurophenol Blend” is a proprietary blend — the label gives one combined amount (300 mg) without saying how much of each component you get.

This capsule contains 7 active ingredients centered on curcumin and plant polyphenols (antioxidants). The main active is Longvida Optimized Curcumin extract — a turmeric derivative designed for better absorption.

It also includes grape extract and wild blueberry extract, both rich in flavonoids and proanthocyanidins (natural plant compounds), plus a proprietary Neurophenol Blend that combines resveratrol, flavonoids, and anthocyanins. The product rounds out with flavan-3-ols and phenolic acids, all compounds that function as antioxidants in your body.

Inactive ingredients — the capsule shell and various fillers and binders — are also present but play no active role in the product's effects.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Oral mucositis — rated "Possibly Effective" (Turmeric) (Natural Medicines).
  • On file: Allergic rhinitis (hay fever) — rated "Possibly Effective" (Turmeric) (Natural Medicines).
  • On file: Nonalcoholic fatty liver disease (NAFLD) — rated "Possibly Effective" (Turmeric) (Natural Medicines).
  • On file: Hyperlipidemia — rated "Possibly Effective" (Turmeric) (Natural Medicines).
  • On file: Pruritus — rated "Possibly Effective" (Turmeric) (Natural Medicines).

Evidence for this combination is limited. Grape extract is possibly effective for chronic venous insufficiency (CVI) — a condition where blood pools in leg veins — but possibly ineffective for hay fever, nausea from chemotherapy, and obesity.

Wild blueberry extract's evidence is insufficient to rate for cognitive decline, anxiety, athletic performance, heart disease, and cholesterol; it is possibly ineffective for high blood pressure. Longvida Optimized Curcumin extract is possibly effective for depression, high cholesterol, hay fever, and indigestion, but evidence is insufficient for many other uses.

The product as a whole does not have established effectiveness data for any single condition.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Grape extract as food is fine during pregnancy, but concentrated supplements and wine should be avoided due to limited safety data and alcohol content; when breastfeeding, there is not enough information on concentrated grape supplements. Wild blueberry and curcumin extracts are rated Likely Safe in pregnancy and lactation based on the data we hold, though concentrated blueberry supplements have not been well studied in pregnancy and high-dose extracts' safety while breastfeeding is unknown.

For turmeric specifically, food amounts are likely fine, but medicinal or supplement doses should be approved by your doctor during pregnancy, and there is insufficient data on supplement doses during lactation.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Grape, Turmeric, Blueberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; cancer treatments; diabetes medications.
  • For scale: 1,215 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take blood thinners or antiplatelet drugs (Moderate severity), check with your pharmacist first — grape extract may increase bleeding risk. Also screen drugs broken down by your liver's CYP450 enzymes, including diabetes medications, cyclosporine, tacrolimus, tamoxifen, sulfasalazine, methotrexate, tramadol, chemotherapy drugs, flurbiprofen, and buspirone (Moderate and Minor severity).

Discuss these with your doctor or pharmacist before you start.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This is a polyphenol-rich blend that may appeal to you if you're interested in antioxidant support, though solid evidence of benefit is limited. If you take any prescription medications — especially blood thinners, diabetes drugs, tacrolimus, tamoxifen, sulfasalazine, methotrexate, chemotherapy, or cyclosporine — you'll need to check your exact medications with your pharmacist or doctor before starting.

The turmeric content carries a small risk of liver problems with long-term use, and the combination can cause gastrointestinal upset. Talk it over with your own healthcare provider to see if this product makes sense for your situation.

Longvida Optimized Curcumin extract24 drug types · 1,133 drugs

Alkylating Agents

Turmeric has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
In vitro research suggests that curcumin, a constituent of turmeric, inhibits mechlorethamine-induced apoptosis of breast cancer cells by up to 70%. Also, animal research shows that curcumin inhibits cyclophosphamide-induced tumor regression. However, some in vitro research shows that curcumin does not affect the apoptosis capacity of etoposide. Also, other laboratory research suggests that curcumin might augment the cytotoxic effects of alkylating agents. Reasons for the discrepancies may relate to the dose of curcumin and the specific chemotherapeutic agent. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects. More evidence is needed to determine what effect, if any, turmeric might have on alkylating agents.

Likelihood Possible Evidence D
Amlodipine (Norvasc)

Taking turmeric with amlodipine may increase levels of amlodipine.
Animal research shows that giving amlodipine 1 mg/kg as a single dose following the use of turmeric extract 200 mg/kg daily for 2 weeks increases the maximum concentration and area under the curve by 53% and 56%, respectively, when compared with amlodipine alone. Additional animal research shows that taking amlodipine 1 mg/kg with a curcumin 2 mg/kg pretreatment for 10 days increases the maximum concentration and area under the curve by about 2-fold when compared with amlodipine alone.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Turmeric may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Curcumin, a constituent of turmeric, has demonstrated antiplatelet effects in vitro. Furthermore, two case reports have found that taking turmeric along with warfarin or fluindione was associated with an increased international normalized ratio (INR). However, one clinical study in healthy volunteers shows that taking curcumin 500 mg daily for 3 weeks, alone or with aspirin 100 mg, does not increase antiplatelet effects or bleeding risk. It is possible that the dose of turmeric used in this study was too low to produce a notable effect.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking turmeric with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research and case reports suggest that curcumin, a turmeric constituent, can reduce blood glucose levels in patients with diabetes. Furthermore, clinical research in adults with type 2 diabetes shows that taking curcumin 475 mg daily for 10 days prior to taking glyburide 5 mg decreased postprandial glucose levels for up to 24 hours when compared with glyburide alone, despite the lack of a significant pharmacokinetic interaction. Other clinical studies in patients with diabetes show that taking curcumin daily can reduce blood glucose levels when compared with placebo.

Likelihood Possible Evidence B
Antitumor Antibiotics

Turmeric has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
In vitro and animal research shows that curcumin, a constituent of turmeric, inhibits doxorubicin-induced apoptosis of breast cancer cells by up to 65%. However, curcumin does not seem to affect the apoptosis capacity of daunorubicin. In fact, some research shows that curcumin might augment the cytotoxic effects of antitumor antibiotics, increasing their effectiveness. Reasons for the discrepancies may relate to the dose of curcumin and the chemotherapeutic agent. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects. More evidence is needed to determine what effects, if any, antioxidants such as turmeric have on antitumor antibiotics.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Turmeric might increase or decrease levels of drugs metabolized by CYP3A4.
In vitro and animal research show that turmeric and its constituents curcumin and curcuminoids inhibit CYP3A4. Also, 8 case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking turmeric and cancer medications that are CYP3A4 substrates, including everolimus, ruxolitinib, ibrutinib, and palbociclib, and bortezomib. In another case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels after consuming turmeric powder at a dose of 15 or more spoonfuls daily for ten days prior. It was thought that turmeric increased levels of tacrolimus due to CYP3A4 inhibition.
Conversely, other in vitro research suggests that turmeric induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. An animal model suggests that induction of CYP3A4 occurs after daily curcumin use for 1 week. However, the induction of CYP3A4 by turmeric has not been reported in humans.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, turmeric might increase the risk of liver damage when taken with hepatotoxic drugs.
There is concern that turmeric might cause hepatotoxicity, especially when highly bioavailable formulations are used in high doses.

Likelihood Possible Evidence D
Methotrexate (Trexall, Others)

Theoretically, turmeric might have additive effects when used with hepatotoxic drugs such as methotrexate.
In one case report, a 39-year-old female taking methotrexate, turmeric, and linseed oil developed hepatotoxicity.

Likelihood Possible Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, turmeric might increase blood levels of OATP4C1 substrates.
In vitro research shows that the turmeric constituent curcumin competitively inhibits OATP4C1 transport. This transporter is expressed in the kidney and facilitates the renal excretion of certain drugs. Theoretically, taking turmeric might decrease renal excretion of OATP substrates.

Likelihood Possible Evidence D
Sulfasalazine (Azulfidine)

Turmeric might increase the effects and adverse effects of sulfasalazine.
Clinical research shows that taking the turmeric constituent, curcumin, can increase blood levels of sulfasalazine by 3.2-fold.

Likelihood Probable Evidence B
Tacrolimus (Prograf)

Turmeric might increase the effects and adverse effects of tacrolimus.
In one case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels of 29 ng/mL. The patient previously had tacrolimus levels within the therapeutic range at 9.7 ng/mL. Ten days prior to presenting at the emergency room the patient started consumption of turmeric powder at a dose of 15 or more spoonfuls daily. It was thought that turmeric increased levels of tacrolimus due to cytochrome P450 3A4 (CYP3A4) inhibition. In vitro and animal research show that turmeric and its constituent curcumin inhibit CYP3A4.

Likelihood Possible Evidence D
Talinolol

Turmeric may reduce the absorption of talinolol in some situations.
Clinical research shows that taking curcumin for 6 days decreases the bioavailability of talinolol when taken together on the seventh day. The clinical significance of this effect is unclear.

Likelihood Probable Evidence B
Tamoxifen (Nolvadex)

Theoretically, turmeric might reduce the levels and clinical effects of tamoxifen.
In a small clinical trial in patients with breast cancer taking tamoxifen 20-30 mg daily, adding curcumin 1200 mg plus piperine 10 mg three times daily reduces the 24-hour area under the curve of tamoxifen and the active metabolite endoxifen by 12.8% and 12.4%, respectively, as well as the maximum concentrations of tamoxifen, when compared with tamoxifen alone. However, in the absence of piperine, the area under the curve for endoxifen and the maximum concentration of tamoxifen were not significantly reduced. Effects were most pronounced in patients who were extensive cytochrome P450 (CYP) 2D6 metabolizers.

Likelihood Possible Evidence B
Topoisomerase I Inhibitors

Turmeric has antioxidant effects. There is some concern that this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
In vitro research shows that curcumin, a constituent of turmeric, inhibits camptothecin-induced apoptosis of breast cancer cells by up to 71%. However, other in vitro research shows that curcumin augments the cytotoxic effects of camptothecin. Reasons for the discrepancies may relate to the dose of curcumin and the chemotherapeutic agents. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects. More evidence is needed to determine what effect, if any, turmeric might have.

Likelihood Possible Evidence D
Tramadol (Ultram)

Theoretically, turmeric might increase or decrease levels of tramadol.
Animal research suggests that a single dose of curcumin, a constituent of turmeric, may increase tramadol's maximum concentration (Cmax) by inhibiting metabolism, while continued daily use for 7 days may reduce the area under the curve (AUC) due to the induction of drug-metabolizing enzymes such as cytochrome P450 3A4 (CYP3A4). However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Turmeric might increase the risk of bleeding with warfarin.
One case of increased international normalized ratio (INR) has been reported for a patient taking warfarin who began taking turmeric. Prior to taking turmeric, the patient had stable INR measurements. Within a few weeks of starting turmeric supplementation, the patient's INR increased to 10. Additionally, curcumin, the active constituent in turmeric, has demonstrated antiplatelet effects in vitro, which may produce additive effects when taken with warfarin.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, turmeric might increase levels of drugs metabolized by CYP1A2. However, research is conflicting.
In vitro and animal research show that the turmeric constituent, curcumin, inhibits CYP1A2. However, other in vitro research suggests that curcumin does not significantly affect CYP1A2.

Likelihood Possible Evidence D
Docetaxel (Taxotere)

Theoretically, turmeric might increase blood levels of oral docetaxel.
Animal research suggests that the turmeric constituent, curcumin, enhances the oral bioavailability of docetaxel. However, the significance of this interaction is unclear, as this drug is typically administered intravenously in clinical settings.

Likelihood Possible Evidence D
Estrogens

Theoretically, large amounts of turmeric might interfere with hormone replacement therapy through competition for estrogen receptors.
In vitro research shows that curcumin, a constituent of turmeric, displaces the binding of estrogen to its receptors.

Likelihood Possible Evidence D
Glyburide (Diabeta, Others)

Theoretically, taking turmeric and glyburide in combination might increase the risk of hypoglycemia.
Clinical research shows that taking curcumin 475 mg daily for 10 days prior to taking glyburide 5 mg increases blood levels of glyburide by 12% at 2 hours after the dose in patients with type 2 diabetes. While maximal blood concentrations of glyburide were not affected, turmeric modestly decreased postprandial glucose levels for up to 24 hours when compared to glyburide alone, possibly due to the hypoglycemic effect of turmeric demonstrated in animal research.

Likelihood Possible Evidence B
Losartan (Cozaar)

Theoretically, turmeric might increase the effects of losartan.
Research in hypertensive rats shows that taking turmeric can increase the hypotensive effects of losartan.

Likelihood Possible Evidence D
Norfloxacin (Noroxin)

Theoretically, turmeric might increase the effects and adverse effects of norfloxacin.
Animal research shows that taking curcumin, a turmeric constituent, can increase blood levels of orally administered norfloxacin.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, turmeric might increase the absorption of P-glycoprotein substrates.
In vitro and animal research shows that curcuminoids and other constituents found in turmeric can inhibit P-glycoprotein expression and activity.

Likelihood Possible Evidence D
Paclitaxel (Abraxane, Onxol)

Theoretically, turmeric might alter blood levels of paclitaxel, although any effect may not be clinically relevant.
Clinical research in adults with breast cancer receiving intravenous paclitaxel suggests that taking turmeric may modestly alter paclitaxel pharmacokinetics. Patients received paclitaxel on day 1, followed by either no treatment or turmeric 2 grams daily from days 2-22. Pharmacokinetic modeling suggests that turmeric reduces the maximum concentration and area under the curve of paclitaxel by 12.1% and 7.7%, respectively. However, these changes are not likely to be considered clinically relevant. Conversely, animal research suggests that curcumin, a constituent of turmeric, enhances the oral bioavailability of paclitaxel. However, the significance of this interaction is unclear, as this drug is typically administered intravenously in clinical settings.
