HelloPharmacist Scorecard of Passion Formula 450 mg by TerraVita Premium Collection

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 3, 2026

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 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (450 mg) without saying how much of each component you get.

Passion Formula contains 2 active ingredients: tribulus terrestris and jujube (zizyphus). Tribulus is a plant traditionally used for sexual function, while jujube is a fruit used in herbal medicine.

The capsule itself is made from gelatin and water.

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: Sexual dysfunction — rated "Possibly Effective" (Tribulus) (Natural Medicines).

Tribulus shows possibly effective evidence for sexual dysfunction, though the strength of that research is modest. For athletic performance, the evidence suggests it's probably not effective.

For benign prostatic hyperplasia (enlarged prostate), there isn't enough reliable evidence to know whether it works. Jujube lacks established evidence for any of the uses we have data on — aging skin, anemia, anxiety, asthma, and athletic performance all show insufficient reliable evidence to rate.

The evidence, ingredient by ingredient Tribulus Zizyphus

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Tribulus is often well tolerated in the short term by healthy adults, but long-term safety data are limited, and quality varies across products. Serious side effects are rare but have included liver or kidney injury, seizures, and in one extreme case (drinking 2 liters of tribulus water daily), kidney failure requiring dialysis.

More commonly, it may cause stomach pain, cramping, nausea, vomiting, diarrhea, or constipation — though in one study these rates were similar to placebo. Jujube fruit is eaten as food widely, but concentrated supplements haven't been well studied, so safety at medicinal doses isn't clear.

Minor side effects in small studies included headache, diarrhea, dry mouth, and increased bowel movements.

Side effects, ingredient by ingredient Tribulus Zizyphus

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?
  • 2 of the 2 matched ingredients can interact with medications — Tribulus, Zizyphus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 635 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 before starting if you take blood pressure drugs (antihypertensives) or diabetes medications — tribulus may make both work stronger and raise your risk of low blood pressure or low blood sugar. If you take lithium for mood, tribulus might increase its levels.

If you take sedating drugs (CNS depressants) or drugs processed through the CYP1A2 pathway, jujube might affect them. Talk with your doctor or pharmacist about your exact medications first.

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 product may help with sexual dysfunction, though evidence is modest. Because tribulus can lower blood pressure, blood sugar, and lithium levels, and jujube can interact with sedating drugs and diabetes medications, you'll want to check with your doctor or pharmacist before starting it if you take any prescription drugs — especially for blood pressure, diabetes, seizures, or mood.

Long-term safety data are thin, so this is better suited to short-term use in people with no other health concerns.

Jujube3 drug types · 469 drugs

Antidiabetes Drugs

Theoretically, zizyphus might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that zizyphus has hypoglycemic activity. However, a small clinical study shows that zizyphus fruit powder does not reduce fasting blood glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, zizyphus might cause additive sedative effects when taken with CNS depressants.
Some animal research has found that various parts of zizyphus have sedative effects. However, other animal research shows that zizyphus plant extract does not alter sleep parameters when used in combination with pentobarbital.

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

Theoretically, zizyphus might decrease the levels and clinical effects of drugs metabolized by CYP1A2.
Animal research shows that zizyphus induces CYP1A2 enzymes. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Jujube full monograph & interactions

Tribulus Terrestris3 drug types · 259 drugs

Antidiabetes Drugs

Taking tribulus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that Tribulus can lower blood glucose levels in adults with type 2 diabetes who are taking antidiabetes medications.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking tribulus with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that tribulus can lower blood pressure by inhibiting angiotensin-converting enzyme (ACE). Tribulus has also demonstrated hypotensive effects in pre-hypertensive adults.

Likelihood Possible Evidence D
Lithium

Theoretically, tribulus might increase the levels and clinical effects of lithium.
Tribulus is thought to have diuretic properties. Due to these potential diuretic effects, tribulus might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Passion Formula 450 mg by TerraVita Premium Collection: Common Questions

Does Passion Formula 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Passion Formula 450 mg has a known interaction with 635 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Passion Formula 450 mg contains 2 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.
Can I take this while pregnant or breastfeeding?
Tribulus should be avoided during pregnancy because it may affect hormones and safety is not established. It should also be avoided while breastfeeding. Jujube is rated likely safe in pregnancy and lactation, but the product as a whole contains tribulus, so you'd need to talk with your doctor or pharmacist before using it.
What are the most common side effects?
Tribulus may cause stomach pain, cramping, nausea, vomiting, diarrhea, or constipation, though in one study these rates matched placebo. Jujube has caused headache, mild diarrhea, dry mouth, and increased bowel movements in small studies, but these were rare.
Does this really work for sexual dysfunction?
Tribulus is rated possibly effective for sexual dysfunction, meaning there's some evidence it may help — but the research is modest and more work is needed to be certain.
Can I use this long-term?
Tribulus is generally well tolerated in the short term, but long-term safety data are limited. It's best suited to short-term use, and you should discuss any longer-term plan with your doctor or pharmacist.
Is this product third-party tested or quality-checked?
The product facts provided don't include information about third-party testing or quality verification. You may want to contact the manufacturer or check their website for details on quality standards.
Will this help my athletic performance?
Tribulus is rated possibly ineffective for athletic performance, meaning the evidence doesn't support it for that use. Jujube also lacks evidence for athletic performance.
