HelloPharmacist Scorecard of Forskolin by Quality Nature Supplements

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 Jul 11, 2026

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: Forskolin, a compound extracted from the coleus plant. The capsule itself is made with vegetable cellulose as an inactive ingredient.

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 for forskopin is not established for any of the uses listed — angina, asthma, cancer, congestive heart failure, atopic dermatitis (eczema), and dry eye all show insufficient reliable evidence. That means the data we have doesn't yet support a clear rating for how well it works for these conditions.

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.

Taken by mouth, forskolin is generally well tolerated, though a small number of people report constipation, diarrhea, nausea, or vomiting; dose-related diarrhea is the most common concern. The safety data advises against use during pregnancy and while breastfeeding.

Forskolin may lower blood pressure and isn't well studied for long-term use, so if you're considering it, talk with your pharmacist or doctor first.

Major interaction found
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.

Check with your pharmacist before using this product if you take nitrates or calcium channel blockers (Major interactions), or blood pressure medications, blood thinners, warfarin, or drugs processed through the liver enzymes CYP2C9 or CYP3A4 (Moderate interactions).

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.

Forskolin is a single-ingredient supplement with limited evidence for the conditions it's marketed for. If you take heart medications, blood pressure drugs, or blood thinners, this product isn't a fit without a careful check of your specific medicines.

Talk to your pharmacist before starting.

Forskolin7 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 by Quality Nature Supplements: Common Questions

Does Forskolin by Quality Nature Supplements interact with any medications?
Yes. Based on its ingredients, Forskolin 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 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.
Is Forskolin safe to take while pregnant or breastfeeding?
The safety data advises against using it during pregnancy, and there's not enough data to know if it's safe while breastfeeding. Talk with your doctor or pharmacist if you're pregnant, planning to be, or nursing.
What side effects might I notice?
The most common side effects from taking it by mouth are constipation, diarrhea, nausea, and vomiting — especially diarrhea, which can be dose-related. Most people tolerate it well, but if you're sensitive to gastrointestinal changes, start carefully.
Does Forskolin actually work for asthma or heart conditions?
The evidence we hold doesn't establish that it works for asthma, heart failure, angina, or the other conditions on the label. We don't have reliable evidence to rate its effectiveness for any of them.
Can I take Forskolin if I have low blood pressure?
Forskolin may lower blood pressure further, and it's not well studied for long-term use. If you have low blood pressure or take blood pressure medication, talk with your pharmacist before starting.
What's in this product besides the active ingredient?
The only other ingredient is vegetable cellulose, which is the capsule material itself — not a filler added to the formula.
