HelloPharmacist Scorecard of Formula T by Bel-Air Nutrition Corp
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.
What’s inside
Low disclosure
Formula T contains 6 ingredients, including four active botanicals and amino acids. The main actives are L-arginine (an amino acid), Asparagus extract, Ginseng extract, Tongkat Ali extract, and Tribulus terrestris extract.
We also hold one ingredient listed as a Proprietary Herbal Blend — its specific components aren't named on the label, so we cannot tell you what's in it. The product also contains cellulose as an inactive ingredient (a capsule filler).
Does it work?
Moderate evidence
The data we hold shows mixed evidence. Ginseng extract is possibly effective for erectile dysfunction, sexual arousal, influenza, and cognitive function.
Tribulus terrestris and Tongkat Ali are each possibly effective for sexual dysfunction. Ginseng is possibly effective for multiple sclerosis-related fatigue.
However, Tongkat Ali is rated possibly ineffective for athletic performance, and we have insufficient evidence to rate Asparagus for acne, cancer, constipation, high blood pressure, intestinal parasites, or kidney stones. We hold no effectiveness ratings for L-arginine in the data available to us.
How safe is it?
Well-documented data
L-arginine is generally well tolerated short-term but can lower blood pressure and isn't safe for everyone — use only under medical supervision. Common side effects from oral L-arginine include abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing.
Asparagus extract can cause allergic reactions in people sensitive to onions, garlic, or leeks, and a combination product containing asparagus caused constipation, nausea, and other stomach complaints in about half the study group. Ginseng is generally well tolerated for up to 6 months but the long-term safety is uncertain; insomnia is the most common side effect, and serious rare effects include arrhythmia and Stevens-Johnson syndrome.
Tongkat Ali and Tribulus are each generally tolerated short-term, but both carry rare serious risks — Tongkat Ali may raise testosterone beyond normal range (risking acne and liver issues), and Tribulus has rare reports of liver and kidney injury and seizures. The safety data advises against both Ginseng and Tribulus during pregnancy and breastfeeding.
For Tongkat Ali and Asparagus, there isn't enough data to know either way during pregnancy or breastfeeding — talk with your doctor or pharmacist for personalized advice.
Meds to double-check
Moderate interaction found
Before taking Formula T, check with your pharmacist if you use blood pressure medications (especially ACE inhibitors or ARBs), blood thinners, potassium-sparing water pills, diabetes medications, or lithium. Also flag any use of midazolam, furosemide, MAOIs, selegiline, insulin, raltegravir, or propranolol.
All of these have Moderate or Minor interactions documented with one or more ingredients in this product.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This is a multi-ingredient product aimed at sexual function and male health, but it carries significant interaction risks with blood pressure meds, diabetes drugs, blood thinners, and several other classes. If you take any regular medications, check each one against the interaction tool before you start.
Because of the blood pressure and hormone effects, talk to your pharmacist or doctor first — don't self-treat with this.

Formula T by Bel-Air Nutrition Corp Drug Interactions
HelloPharmacist Interaction Report
Formula T by Bel-Air Nutrition Corp contains several active ingredients with documented interactions with medications.
The most serious concern involves L-arginine and blood pressure drugs — it can lower blood pressure further, raising the risk of dangerously low pressure (hypotension). L-arginine also interacts with blood thinners (anticoagulants and antiplatelet drugs), potassium-sparing water pills, diabetes medications, ACE inhibitors, and ARBs (angiotensin receptor blockers), each at Moderate severity.
Read the full breakdown — every affected drug type, severity by severity
Ginseng extract affects a broader range of medications: it can speed up how your liver clears midazolam, reduce the effectiveness of furosemide (a water pill), interfere with MAOIs (a class of antidepressant), alter selegiline levels, increase the risk of low blood sugar (hypoglycemia) with insulin, and possibly raise liver toxicity with raltegravir. Tribulus terrestris extract shares three interactions with L-arginine — blood pressure drugs, diabetes drugs, and lithium — all at Moderate severity.
Asparagus extract can interact with diuretic drugs and lithium, both Moderate. Tongkat Ali carries Minor interactions with propranolol and several liver enzymes.
We could not check a Proprietary Herbal Blend; its ingredients are not specified on the label. Altogether, these interactions span 1,288 individual medications.

Ginseng Extract
Anticoagulant/Antiplatelet Drugs
Although Panax ginseng has shown antiplatelet effects in the laboratory, it is unlikely to increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that ginsenoside constituents in Panax ginseng might decrease platelet aggregation. However, research in humans suggests that ginseng does not affect platelet aggregation. Animal research indicates low oral bioavailability of Rb1 and rapid elimination of Rg1, which might explain the discrepancy between in vitro and human research. Until more is known, use with caution in patients concurrently taking anticoagulant or antiplatelet drugs.
Antidiabetes Drugs
Theoretically, taking Panax ginseng with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research suggests that Panax ginseng might decrease blood glucose levels. Monitor blood glucose levels closely.
Caffeine
Theoretically, taking Panax ginseng with caffeine might increase the risk of adverse stimulant effects.
Panax ginseng has been shown to have stimulant effects. Theoretically, caffeine might have an additive effect on the stimulant effects of Panax ginseng.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, Panax ginseng might increase levels of drugs metabolized by CYP2D6. However, research is conflicting.
There is some evidence that Panax ginseng can inhibit the CYP2D6 enzyme by approximately 6%. In addition, in animal research, Panax ginseng inhibits the metabolism of dextromethorphan, a drug metabolized by CYP2D6, by a small amount. However, contradictory research suggests Panax ginseng might not inhibit CYP2D6. Until more is known, use Panax ginseng cautiously in patients taking drugs metabolized by these enzymes.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, Panax ginseng might increase or decrease levels of drugs metabolized by CYP3A4.
Panax ginseng may affect the clearance of drugs metabolized by CYP3A4. One such drug is imatinib. Inhibition of CYP3A4 was believed to be responsible for a case of imatinib-induced hepatotoxicity. In contrast, Panax ginseng has been shown to increase the clearance of midazolam, another drug metabolized by CYP3A4. Clinical research shows that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29%. Midazolam metabolism was also increased in animals given Panax ginseng. Until more is known, use Panax ginseng cautiously in combination with CYP3A4 substrates.
Estrogens
Theoretically, concomitant use of large amounts of Panax ginseng might interfere with hormone replacement therapy.
Laboratory research and some case reports suggest that Panax ginseng can have estrogenic effects due to competition for estrogen receptors. The estrogenic activity is attributed to the ginsenoside constituents of Panax ginseng.
Furosemide (Lasix)
Theoretically, Panax ginseng might reduce the effects of furosemide.
There is some concern that Panax ginseng might contribute to furosemide resistance. There is one case of resistance to furosemide diuresis in a patient taking a germanium-containing ginseng product.
Imatinib (Gleevec)
Theoretically, Panax ginseng might increase the effects and adverse effects of imatinib.
A case of imatinib-induced hepatotoxicity has been reported for a 26-year-old male with chronic myelogenous leukemia stabilized on imatinib for 7 years. The patient took imatinib 400 mg along with a Panax ginseng-containing energy drink daily for 3 months. Since imatinib-associated hepatotoxicity typically occurs within 2 years of initiating therapy, it is believed that Panax ginseng affected imatinib toxicity though inhibition of cytochrome P450 3A4. CYP3A4 is the primary enzyme involved in imatinib metabolism.
Immunosuppressants
Theoretically, Panax ginseng use might interfere with immunosuppressive therapy.
Panax ginseng might have immune system stimulating properties.
Insulin
Theoretically, taking Panax ginseng with insulin might increase the risk of hypoglycemia.
Clinical research suggests that Panax ginseng might decrease blood glucose levels. Insulin dose adjustments might be necessary in patients taking Panax ginseng; use with caution.
Midazolam (Versed)
Theoretically, Panax ginseng may increase the clearance of midazolam.
Midazolam is metabolized by cytochrome P450 3A4 (CYP3A4). Clinical research suggests that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29%. Midazolam metabolism was also increased in animals given Panax ginseng.
Monoamine Oxidase Inhibitors (Maois)
Theoretically, Panax ginseng can interfere with MAOI therapy.
Concomitant use of Panax ginseng with phenelzine (Nardil) is associated with insomnia, headache, tremors, and hypomania.
Nifedipine (Procardia)
Theoretically, taking Panax ginseng with nifedipine might increase serum levels of nifedipine and the risk of hypotension.
Preliminary clinical research shows that concomitant use can increase serum levels of nifedipine in healthy volunteers. This might cause the blood pressure lowering effects of nifedipine to be increased when taken concomitantly with Panax ginseng.
Qt Interval-Prolonging Drugs
Theoretically, Panax ginseng has an additive effect with drugs that prolong the QT interval and potentially increase the risk of ventricular arrhythmias. However, research is conflicting.
Clinical research shows that short-term use of Panax ginseng can increase the QT interval. However, no changes in QT interval have been identified with prolonged use.
Raltegravir (Isentress)
Theoretically, taking Panax ginseng with raltegravir might increase the risk of liver toxicity.
A case report suggests that concomitant use of Panax ginseng with raltegravir can increase serum levels of raltegravir, resulting in elevated liver enzymes levels.
Selegiline (Eldepryl)
Theoretically, Panax ginseng might increase or decrease levels of selegiline, possibly altering the effects and side effects of selegiline.
Animal research shows that taking selegiline with a low dose of Panax ginseng extract (1 gram/kg) reduces selegiline bioavailability, while taking a high dose of Panax ginseng extract (3 grams/kg) increases selegiline bioavailability. More research is needed to confirm these effects.
Stimulant Drugs
Theoretically, taking Panax ginseng with stimulant drugs might increase the risk of adverse stimulant effects.
Panax ginseng has been shown to have stimulant effects.
Warfarin (Coumadin)
Panax ginseng might affect the clearance of warfarin. However, this interaction appears to be unlikely.
There has been a single case report of decreased effectiveness of warfarin in a patient who also took Panax ginseng. However, it is questionable whether Panax ginseng was the cause of this decrease in warfarin effectiveness. Some research in humans and animals suggests that Panax ginseng does not affect the pharmacokinetics of warfarin. However, other research in humans suggests that Panax ginseng might modestly increase the clearance of the S-warfarin isomer. More evidence is needed to determine whether Panax ginseng causes a significant interaction with warfarin.
Fexofenadine (Allegra)
Theoretically, Panax ginseng might decrease blood levels of oral or intravenous fexofenadine.
Animal research suggests that taking Panax ginseng in combination with oral or intravenous fexofenadine may reduce the bioavailability of fexofenadine. Some scientists have attributed this effect to the ability of Panax ginseng to increase the expression of P-glycoprotein.
Lopinavir/Ritonavir (Kaletra)
Although Panax ginseng has demonstrated variable effects on cytochrome P450 3A4 (CYP3A4), which metabolizes lopinavir, Panax ginseng is unlikely to alter levels of lopinavir/ritonavir.
Lopinavir is metabolized by CYP3A4 and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Panax ginseng has shown variable effects on CYP3A4 activity in humans. However, taking Panax ginseng (Vitamer Laboratories) 500 mg twice daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in 12 healthy volunteers.
L-Arginine
Ace Inhibitors (Aceis)
Theoretically, concomitant use of L-arginine and ACE inhibitors may increase the risk for hypotension and hyperkalemia.
Combining L-arginine with some antihypertensive drugs, especially ACE inhibitors, seems to have additive vasodilating and blood pressure-lowering effects. Furthermore, ACE inhibitors can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ACE inhibitors with L-arginine may increases the risk of hyperkalemia.
Angiotensin Receptor Blockers (Arbs)
Theoretically, concomitant use of L-arginine and ARBs may increase the risk of hypotension and hyperkalemia.
L-arginine increases nitric oxide, which causes vasodilation. Combining L-arginine with ARBs seems to increase L-arginine-induced vasodilation. Furthermore, ARBs can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ARBs with L-arginine may increases the risk of hyperkalemia.
Anticoagulant/Antiplatelet Drugs
Theoretically, concomitant use of L-arginine with anticoagulant and antiplatelet drugs might have additive effects and increase the risk of bleeding.
Preliminary research suggests that L-arginine infusions reduce platelet aggregation in humans. The clinical significance of this effect is unclear.
Antidiabetes Drugs
Theoretically, concomitant use of L-arginine might have additive effects with antidiabetes drugs.
Preliminary clinical research shows that L-arginine decreases blood glucose levels in patients with type 2 diabetes.
Antihypertensive Drugs
Theoretically, concomitant use of L-arginine and antihypertensive drugs may increase the risk of hypotension.
L-arginine increases nitric oxide, which causes vasodilation. Clinical evidence shows that L-arginine can reduce blood pressure in some individuals with hypertension. Furthermore, combining L-arginine with some antihypertensive drugs seems to have additive vasodilating and blood pressure-lowering effects.
Isoproterenol (Isuprel)
Theoretically, concurrent use of isoproterenol and L-arginine might result in additive effects and hypotension.
Preliminary clinical evidence suggests that L-arginine enhances isoproterenol-induced vasodilation in patients with essential hypertension or a family history of essential hypertension.
Potassium-Sparing Diuretics
Theoretically concomitant use of potassium-sparing diuretics with L-arginine may increases the risk of hyperkalemia.
Potassium-sparing diuretics can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients.
Sildenafil (Viagra)
Theoretically, concurrent use of sildenafil and L-arginine might increase the risk for hypotension.
In vivo, concurrent use of L-arginine and sildenafil has resulted in increased vasodilation. Theoretically, concurrent use might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.
Testosterone
Theoretically, concomitant use of L-arginine and testosterone might have additive effects.
In clinical research, L-arginine increases the level of testosterone in male patients with erectile dysfunction. The clinical significance of this finding is unclear.
Tribulus terrestris extract
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.
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.
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.
Tongkat Ali extract
Propranolol (Inderal)
Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism. It is not known if separating administration will prevent this interaction.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes. This effect has not been reported in humans.
Cytochrome P450 2A6 (Cyp2A6) Substrates
Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes. This effect has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes. This effect has not been reported in humans.
Testosterone
Theoretically, Eurycoma longifolia may further increase levels of testosterone.
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo. It is unclear whether this increase would occur in individuals with normal testosterone levels.
Asparagus Extract
Diuretic Drugs
Theoretically, asparagus root might increase diuresis and electrolyte loss when used with diuretic drugs.
Animal studies show that asparagus root extracts have diuretic effects. This effect has not been reported in humans.
Lithium
Theoretically, asparagus root might cause diuresis, reducing lithium clearance.
Animal studies show that asparagus root extracts have diuretic effects. Theoretically, this might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.
