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 4 active ingredients.
  • “OptiNOs” is listed as a grouped ingredient — the label gives one combined amount (450 mg) without saying how much of each component you get.

Plasma Muscle contains four active ingredients. PEAK ATP (adenosine) is a molecule your cells naturally produce for energy signaling.

Turmeric extract provides curcumin, the active compound in the turmeric plant. Veldt Grape extract is derived from Cissus quadrangularis.

Bishop's Weed extract comes from the bishop's weed plant. The product is encapsulated and contains sesame oil as an inactive ingredient.

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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Builds lean muscle and increases strength.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Exercise-induced muscle soreness, Muscle strength, Physical performance, Muscle hypertrophy — and 2 related terms.
  • The closest evidence on file: Turmeric is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Turmeric is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness, Physical performance, Exercise-induced muscle damage.
  • Also on file: Adenosine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance.

The data we hold reflects the evidence for these ingredients used in clinical and research settings, though not necessarily for muscle performance in the way this product markets them. PEAK ATP shows effectiveness for certain heart rhythm problems and cardiovascular diagnostics in medical use.

Turmeric extract is possibly effective for depression, high cholesterol, hay fever, and indigestion. Veldt Grape extract is possibly effective for obesity, but evidence is insufficient to rate it for high cholesterol, bone loss, cancer, or seizures.

We don't hold effectiveness ratings for Bishop's Weed in the data we have.

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

PEAK ATP (adenosine) carries important cautions: the prescription injectable form is powerful and used only under medical supervision, and while oral adenosine supplements have limited safety evidence, the injectable form can cause serious cardiovascular and respiratory side effects. Turmeric extract is generally well tolerated in food amounts, but concentrated supplements may cause stomach upset, and rare cases of liver damage have been reported with supplement use lasting 2 weeks to 14 months; most resolved when the supplement was stopped.

Veldt Grape extract is generally well tolerated short-term but long-term safety is unclear; it may cause headache or insomnia at rates similar to placebo. Bishop's Weed contains light-sensitizing compounds and carries the risk of photoreactivity and skin reactions—it should be used only under medical supervision.

The safety data advises against using Cissus quadrangularis and Bishop's Weed during pregnancy, and against using Bishop's Weed while breastfeeding. For Turmeric extract and PEAK ATP, there is no pregnancy or breastfeeding information on file—talk with your pharmacist or doctor for personalized guidance if you are pregnant or nursing.

Turmeric 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.

Bishop's Weed extract3 drug types · 954 drugs

Anticoagulant/Antiplatelet Drugs

Bergapten, a constituent of bishop's weed, has antiplatelet activity. Theoretically, bishop's weed might have additive effects with anticoagulant or antiplatelet drugs and possibly increase the risk of bleeding.
Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

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

Bergapten, a constituent of bishop's weed, has been shown to inhibit cytochrome P450 3A4 (CYP3A4) in vitro. Theoretically, bishop's weed might inhibit elimination and increase blood levels of drugs metabolized by CYP3A4.
Some drugs metabolized by CYP3A4 include alprazolam (Xanax), amitriptyline (Elavil), amiodarone (Cordarone), buspirone (Buspar), cerivastatin (Baycol), citalopram (Celexa), felodipine (Plendil), fexofenadine (Allegra), itraconazole (Sporanox), ketoconazole (Nizoral), lansoprazole (Prevacid), losartan (Cozaar), lovastatin (Mevacor), ondansetron (Zofran), prednisone (Deltasone, Orasone), sertraline (Zoloft), sibutramine (Meridia), sildenafil (Viagra), simvastatin (Zocor), verapamil (Calan, Covera-HS, Isoptin), and many others.

Likelihood Possible Evidence B
Photosensitizing Drugs

Bishop's weed constituents seem to cause photosensitivity. Theoretically, concomitant use of bishop's weed with photosensitizing drugs might result in increased photosensitivity.
Some drugs that cause photosensitivity include amitriptyline (Elavil), quinolones (Ciprofloxacin, others), sulfa drugs (Septra, Bactrim, others), and tetracycline.

PEAK ATP3 drug types · 47 drugs

Dipyridamole (Persantine)

Dipyridamole can increase the therapeutic and toxic effects of adenosine.
Dipyridamole decreases the metabolism of adenosine. Intravenous infusion of adenosine in patients who are taking dipyridamole can cause dizziness, bradycardia, and syncope. Dipyridamole should be discontinued for several days prior to a cardiac stress test using adenosine.

Likelihood Likely Evidence D
Carbamazepine (Tegretol)

Carbamazepine might increase the risk of heart block when used concomitantly with adenosine.
Carbamazepine and adenosine can both cause heart block. Giving them concurrently might produce an additive effect.

Likelihood Possible Evidence D
Methylxanthines

Methylxanthines are competitive antagonists of adenosine and can block its pharmacologic effects.
The methylxanthines, aminophylline, caffeine, and theophylline, can block the effects of adenosine by acting as competitive antagonists at adenosine cell surface receptors. It is recommended that methylxanthines be avoided for 24 hours prior to cardiac stress tests.

Yes. Based on its ingredients, Plasma Muscle has a known interaction with 1,292 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Plasma Muscle contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is PEAK ATP and why is it in this product?
PEAK ATP is adenosine, a molecule your cells produce naturally for energy signaling. In prescription form it's used medically for certain heart rhythm problems and heart imaging tests. This product includes it as an oral supplement, though evidence for oral adenosine safety is limited.
Can I take this if I'm pregnant or breastfeeding?
For PEAK ATP and Turmeric extract, we don't hold pregnancy or breastfeeding safety data, so you'll need to talk with your doctor or pharmacist. For Cissus quadrangularis (Veldt Grape extract) and Bishop's Weed extract, the safety data advises against use during pregnancy and breastfeeding. Get personalized advice before taking this product if you're pregnant or nursing.
What side effects might I experience?
Turmeric extract may cause stomach upset (constipation, diarrhea, nausea, or reflux) and rarely headache. Veldt Grape extract may cause headache or insomnia at rates similar to placebo. Bishop's Weed can cause nausea, vomiting, or headache orally, and sun sensitivity if applied to skin. The safety evidence for oral PEAK ATP is limited and has not been thoroughly studied.
Is turmeric in this product safe long-term?
Turmeric is generally well tolerated as food, but concentrated supplements may cause side effects. Rare cases of liver damage have been reported with supplement use lasting 2 weeks to 14 months, though most resolved when stopped. If you take this long-term, periodic check-ins with your pharmacist or doctor are wise, especially if you have liver concerns.
Why do I need to avoid caffeine with PEAK ATP?
Caffeine and similar stimulants (methylxanthines) block the effects of adenosine by competing for the same cell receptors. To let PEAK ATP work, you'd want to avoid caffeine for 24 hours before using the supplement.
