HelloPharmacist Scorecard of Forskolin Extract by Integrative Therapeutics

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
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: coleus forskohlii root extract. Coleus is a plant whose root has been studied for various health purposes, including heart function and breathing.

The extract is the concentrated form of the plant material, which contains forsklin — the compound responsible for many of coleus's effects in your body. The capsule also contains inactive ingredients (cellulose, hydroxypropyl methylcellulose, magnesium stearate, and silicon dioxide) that help hold the extract together and allow you to swallow it easily.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Coleus product and its label doesn't state a use — see Coleus's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold doesn't establish that Forskolin Extract is reliably effective for any of the conditions it's marketed for — angina, asthma, cancer, congestive heart failure, atopic dermatitis (eczema), and dry eye all carry a rating of insufficient reliable evidence. That doesn't mean it doesn't work; it means the scientific data available to us isn't robust enough yet to make a confident claim about whether it does.

The evidence, ingredient by ingredient Coleus

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Coleus is generally well tolerated when taken by mouth, but it does come with caveats. Gastrointestinal side effects are the most common — diarrhea, nausea, vomiting, and constipation — with some trial data showing loose stools in a small proportion of participants and retrospective reports suggesting roughly a 10% rate of GI upset overall, mostly diarrhea.

The supplement may lower your blood pressure, so it's not well studied for long-term use and warrants professional guidance. The safety data advises against taking coleus during pregnancy or while breastfeeding — there isn't enough information to know it's safe in either situation.

If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist before considering this product.

Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Coleus.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 916 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.

Before you take this product, check with your doctor or pharmacist if you're on nitrates or calcium channel blockers (both Major severity interactions), blood pressure medications, blood thinners or antiplatelet drugs like aspirin, warfarin specifically, or any medication cleared through your liver's CYP3A4 or CYP2C9 pathways (all Moderate severity).

Coleus forskohlii root extract7 drug types · 915 drugs

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.

Likelihood Probable Evidence B
Nitrates

Theoretically, combining coleus with nitrates might increase the coronary vasodilatory effects.
Forskolin, a constituent of coleus, and nitrates both cause coronary vasodilatory effects.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Forskolin Extract by Integrative Therapeutics: Common Questions

Does Forskolin Extract by Integrative Therapeutics interact with any medications?
Yes. Based on its ingredients, Forskolin Extract has a known interaction with 915 medications, including 29 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Forskolin Extract contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 are the most common side effects if I take this?
The most common side effects from taking coleus by mouth are gastrointestinal — diarrhea, nausea, vomiting, and constipation. Some trial participants experienced loose stools or increased bowel movements. If these bother you, it may be dose-related, so talk with your doctor or pharmacist.
Can I take this if I'm pregnant or breastfeeding?
The safety data advises against it. There isn't enough information to know whether coleus is safe during pregnancy or while breastfeeding. If you're in either situation, talk with your doctor or pharmacist before starting this supplement.
Does this actually work for heart health or asthma?
We don't have reliable evidence that it does. The product is marketed for several conditions — including angina, asthma, heart failure, and others — but the scientific data we hold rates all of them as having insufficient evidence to make a confident claim about whether it works.
How might this affect my blood pressure?
Coleus may lower blood pressure, which is why it interacts with blood pressure medications and carries a caution for long-term use. If you have low blood pressure or take a blood pressure drug, talk with your doctor or pharmacist before taking this.
What's in the capsule besides the active ingredient?
The capsule contains cellulose, hydroxypropyl methylcellulose, magnesium stearate, and silicon dioxide — these are inactive ingredients that help keep the supplement stable and make it easy to swallow. They're not the active part.
Is this safe to use with my medications?
We've identified interactions with many medication categories — heart drugs, blood thinners, blood pressure meds, and others metabolized by your liver. Before you take it, use the medication search tool on this page to check your exact prescriptions, and talk with your doctor or pharmacist.
