HelloPharmacist Scorecard of Coleus Forskohlii 90 mg by Vital Nutrients
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
Full disclosure
This product contains one active ingredient: coleus forskohlii root extract at 90 mg per capsule. The inactive ingredients are rice powder, cellulose, and silica—standard capsule fillers and binders.
Does it work?
Couldn't assess
The evidence for coleus isn't established in our data. We hold insufficient reliable evidence to rate it for angina, asthma, cancer, congestive heart failure, atopic dermatitis (eczema), or dry eye—the six uses we have information on.
That doesn't mean it doesn't work; it means larger or better-designed studies would be needed to know.
How safe is it?
Well-documented data
Coleus seems to be generally well tolerated when taken by mouth, though gastrointestinal side effects do occur. The most common are diarrhea, constipation, nausea, and vomiting.
In one clinical trial, about 1 in 15 patients reported increased bowel movements or loose stools. Retrospective reports suggest roughly 10% of people experience some gastrointestinal upset, mostly diarrhea.
Because coleus can lower blood pressure and isn't well studied for long-term use, it needs careful monitoring and professional guidance. The safety data advises against use during pregnancy and while breastfeeding—there isn't enough information to know it's safe in either situation.
Talk with your doctor or pharmacist before taking coleus if you're pregnant, planning to become pregnant, or nursing.
Meds to double-check
Major interaction found
Before taking this product, double-check with your pharmacist if you use heart medications—especially nitrates or calcium channel blockers (Major severity). Also flag antihypertensive drugs, blood thinners, warfarin, or any medication metabolized by your liver's CYP2C9 or CYP3A4 enzymes (Moderate severity).
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Coleus forskohlii might be worth considering if you're looking to explore options for heart or respiratory conditions—but the evidence for those uses isn't solid yet. If you take any heart medications, blood thinners, blood pressure drugs, or any prescription at all, check with your pharmacist first.
This product needs careful handling and isn't for pregnancy or breastfeeding.

Coleus Forskohlii 90 mg by Vital Nutrients Drug Interactions
HelloPharmacist Interaction Report
Coleus Forskohlii 90 mg by Vital Nutrients contains one active ingredient—coleus forskohlii root extract—that interacts with a number of medications.
The most serious concerns are with heart medications: nitrates (like nitroglycerin) and calcium channel blockers (like diltiazem or verapamil) both carry a Major severity rating. Coleus contains forskolin, which widens blood vessels in the heart, and combining it with these drugs could amplify that effect dangerously.
Read the full breakdown — every affected drug type, severity by severity
Moderate interactions span several other drug types. Antihypertensive drugs (blood pressure medications) may have their effects boosted, increasing the risk of low blood pressure.
Blood thinners and antiplatelet drugs (like warfarin, aspirin, or clopidogrel) may see increased bleeding or bruising risk. Coleus can also affect how your liver metabolizes certain medications—specifically those processed by CYP2C9 and CYP3A4 enzymes—which might reduce their effectiveness or raise their levels in your blood.
Altogether, these interactions span 916 individual medications. Before you start coleus, run your exact prescriptions through the checker on this page.

For each ingredient in Coleus Forskohlii 90 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Coleus forskohlii Root Extract
Calcium Channel Blockers
Theoretically, combining coleus with calcium channel blockers might increase the coronary vasodilatory effects.
Forskolin, a constituent of coleus, and calcium channel blockers both cause coronary vasodilatory effects.
Nitrates
Theoretically, combining coleus with nitrates might increase the coronary vasodilatory effects.
Forskolin, a constituent of coleus, and nitrates both cause coronary vasodilatory effects.
Anticoagulant/Antiplatelet Drugs
Theoretically, concomitant use of coleus and anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro and animal research shows that forskolin, a constituent of coleus, can inhibit platelet aggregation and adhesion.
Antihypertensive Drugs
Theoretically, combining coleus with antihypertensive drugs might cause additive blood pressure lowering effects and increase the risk of hypotension.
Animal research shows that forskolin, a constituent of coleus, may lower blood pressure.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, taking coleus may affect drugs metabolized by CYP2C9 and increase the risk of adverse effects or reduce the effectiveness.
Research on the effect of coleus on CYP2C9 is conflicting. Some animal research shows that coleus extract can induce CYP2C9, while in vitro research shows that coleus can inhibit CYP2C9. Until more is known, advise patients that taking coleus might increase or decrease levels of drugs metabolized by CYP2C9.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, taking coleus might decrease serum levels of drugs metabolized by CYP3A4.
In vitro research shows that coleus can activate the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. Although the clinical significance of this is not known, use caution when considering concomitant use of coleus and other drugs affected by these enzymes.
Warfarin (Coumadin)
Theoretically, taking coleus may affect the metabolism of warfarin and increase the risk of adverse effects or reduce the effectiveness.
Some animal research shows that coleus extract can induce cytochrome P450 2C9 (CYP2C9), an enzyme that metabolizes warfarin. However, other in vitro research shows that coleus can inhibit CYP2C9. Theoretically, taking coleus with drugs metabolized by CYP2C9 might affect drug levels and the risk of adverse effects. Until more is known, advise patients that taking coleus might increase or decrease levels of warfarin.
