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 0 of its 10 active ingredients.

Tranquil Ability contains 10 ingredients, of which the active ones are astragalus, muira puama, California poppy, una de gato (cat's claw), chuchuhuasi, tayuya, mulungu, and wild lettuce. The product also contains 35–40% organic alcohol and distilled water as a base.

There are no inactive fillers or binders listed.

Does it work?

Not established
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: promotes restful state and emotional well-being.
  • We looked for evidence on: Anxiety, Insomnia, Sleep quality, Nervous tension, Restlessness.
  • The closest evidence on file: California Poppy is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: California Poppy is rated "Insufficient Reliable Evidence To Rate" for Insomnia.

The evidence for most of the active ingredients in this product isn't established in the data we hold. Astragalus, muira puama, California poppy, cat's claw, and wild lettuce all have been studied for various conditions—including hay fever, joint pain, anxiety, sleep, and immune support—but none have sufficient reliable evidence to rate their effectiveness for those uses.

Chuchuhuasi similarly lacks effectiveness data in our records.

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 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Astragalus, California poppy, cat's claw, and wild lettuce are generally well tolerated in the short term in healthy adults, though long-term safety data are limited for most of them. However, the safety data for this product during pregnancy and breastfeeding advise against use: astragalus, California poppy, cat's claw, and wild lettuce should all be avoided during pregnancy, and the same applies to breastfeeding.

Cat's claw has been traditionally used as an abortifacient and carries a "possibly unsafe" rating in pregnancy; the others simply lack sufficient safety data. Muira puama and chuchuhuasi also lack enough safety information to recommend them during pregnancy or lactation.

Reported side effects with astragalus in oral form include dizziness and, in rare cases, heart-related effects; California poppy in combination formulas has been reported to cause muscular stiffness, morning fatigue, and nausea, though it's unclear if poppy alone is responsible. Cat's claw has been linked to blood cell changes, kidney injury, and neurological effects in clinical studies, though most patients in those studies had advanced cancer.

Wild lettuce in large amounts or if harvested prematurely can cause serious effects including respiratory depression and coma, but properly harvested mature wild lettuce appears well tolerated.

Meds to double-check

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?
  • 4 of the 6 matched ingredients can interact with medications — California Poppy, Wild Lettuce, Cat's Claw, Astragalus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,285 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.

Check with your own doctor or pharmacist before taking Tranquil Ability if you use any of the following: diabetes medications (astragalus may lower blood sugar), CNS depressants like sleep aids or anti-anxiety drugs (California poppy and wild lettuce), blood pressure medications including antihypertensives and calcium channel blockers (cat's claw), blood thinners or antiplatelet drugs (cat's claw), immunosuppressants (astragalus and cat's claw), lithium (astragalus), cyclophosphamide (astragalus), anticholinergic drugs (wild lettuce), or nirmatrelvir/ritonavir (cat's claw).

Each ingredient & the kinds of drugs it affects

For each ingredient in Tranquil Ability with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Una de Gato6 drug types · 964 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, cat's claw may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Cat's claw contains rhynchophylline and isorhynchophylline. Animal research suggests that these alkaloids can inhibit platelet aggregation. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking cat's claw with antihypertensive drugs might increase the risk of hypotension.
Cat's claw contains rhynchophylline. In vitro and animal research suggests that rhynchophylline can lower blood pressure. This interaction has not been reported in humans.

Likelihood Probable Evidence D
Calcium Channel Blockers

Theoretically, taking cat's claw with calcium channel blockers might increase the risk of hypotension.
Cat's claw contains various alkaloids, including rhynchophylline, isorhynchophylline, corynoxeine, and isocorynoxiene. Animal research suggests that these alkaloids can lower blood pressure by acting as calcium channel blockers. This interaction has not been reported in humans.

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

Theoretically, cat's claw might increase or decrease the levels and effects of drugs metabolized by CYP3A4.
Cat's claw may affect the clearance of drugs metabolized by CYP3A4. In vitro research shows that cat's claw can inhibit CYP3A4 enzymes. In one case report, a patient taking cat's claw (at an unspecified dose) experienced increased serum levels of atazanavir, ritonavir, and saquinavir, all of which are CYP3A4 substrates. Levels returned to normal 15 days after discontinuation of the cat's claw supplement, suggesting inhibition of CYP3A4 by cat's claw. In contrast, animal research suggests that rhynchophylline, an alkaloid contained in cat's claw, induces CYP3A expression and accelerates the metabolism of nirmatrelvir, the active component in the nirmatrelvir/ritonavir combination product.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, cat's claw might interfere with immunosuppressive therapy.
In human and laboratory research, cat's claw has been shown to have immunostimulating activity. It stimulates phagocytosis and increases respiratory cellular activity and the mobility of leukocytes. Theoretically, this could interfere with the activity of immunosuppressant medications.

Likelihood Possible Evidence D
Nirmatrelvir/Ritonavir (Paxlovid)

Theoretically, cat's claw may decrease the levels of nirmatrelvir.
Cat's claw contains rhynchophylline. Animal research suggests that this alkaloid induces CYP3A expression, thereby accelerating the metabolism of nirmatrelvir, the active component in the nirmatrelvir/ritonavir combination product. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Una de Gato full monograph & interactions

Wild Lettuce2 drug types · 393 drugs

Anticholinergic Drugs

Studies report varying evidence on whether or not wild lettuce contains hyoscyamine, an anticholinergic drug. If it does, it appears to be in very low amounts. Nevertheless, there have been case reports of individuals consuming large amounts of wild lettuce experiencing anticholinergic-related side effects, such as constipation, dry mouth, dizziness, and sweating. Therefore, if you are already taking a drug with anticholinergic effects, you should be cautious about combining it with wild lettuce as the risk of side effects may be increased.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, concomitant use with drugs with sedative effects might cause additive therapeutic effects and adverse effects.

Likelihood Possible Evidence D
Wild Lettuce full monograph & interactions

California Poppy1 drug type · 248 drugs

Cns Depressants

Theoretically, taking California poppy with drugs with sedative effects may increase the risk of sedative effects.
Laboratory research shows that California poppy has sedative effects.

Likelihood Possible Evidence D
California Poppy full monograph & interactions

Astragalus4 drug types · 208 drugs

Antidiabetes Drugs

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research in humans shows that astragalus might have hypoglycemic effects. Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.

Likelihood Probable Evidence A
Cyclophosphamide

Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.
