HelloPharmacist Scorecard of Forskolin 125 mg by Puritan's Pride

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: ForsLean Coleus forskohlii root extract at 125 mg per capsule. Forskolin is the compound in coleus that researchers have studied most closely.

The capsule itself is filled with inactive ingredients — dicalcium phosphate, vegetable cellulose, and gelatin — that help form and protect the tablet.

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 for coleus and forskolin in your body isn't established yet in our data. The facts we hold list six potential uses — angina, asthma, cancer, congestive heart failure, atopic dermatitis (eczema), and dry eye — but for all of them, the rating is insufficient reliable evidence.

That means the research so far hasn't been strong enough to say whether it works. Talk to your doctor or pharmacist if you're thinking about using this for a specific condition.

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 seems to be generally well tolerated when taken by mouth, though gastrointestinal side effects do occur. The most common are constipation, diarrhea, nausea, and vomiting.

One trial reported loose stools in a small number of participants, and retrospective reports suggest about a 10% rate of gastrointestinal effects overall, with diarrhea accounting for most of them. Coleus may lower blood pressure and isn't well studied long-term, so it should be used with professional guidance.

The safety data advises against use during pregnancy and while breastfeeding. Not enough is known about its effects in these situations.

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 these medication types before taking this product: nitrates and calcium channel blockers (Major severity), then blood pressure medications, blood thinners, antiplatelet drugs, and warfarin (Moderate severity). You'll also need to verify any drugs your liver metabolizes via CYP2C9 or CYP3A4 enzymes.

ForsLean 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 125 mg by Puritan's Pride: Common Questions

Does Forskolin 125 mg by Puritan's Pride interact with any medications?
Yes. Based on its ingredients, Forskolin 125 mg 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 125 mg 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 is ForsLean and how does coleus work?
ForsLean is a standardized extract from the Coleus forskohlii plant root. Forskolin is the active compound researchers focus on, and animal studies suggest it may affect blood pressure and heart function. However, reliable evidence in humans is still lacking for the conditions listed on this product.
Can I take this if I'm pregnant or nursing?
The safety data advises against use during pregnancy, and there isn't enough safety information for breastfeeding either. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, planning to become pregnant, or breastfeeding.
What side effects might I experience?
The most common side effects when taken by mouth are loose stools, diarrhea, nausea, vomiting, and constipation. Gastrointestinal effects happen in a small number of people — roughly 10% in reported cases, mostly diarrhea. These are usually dose-related.
Is this safe to take long-term?
Coleus isn't well studied for long-term use, and the safety data recommends caution and professional guidance if you decide to use it. Talk with your doctor or pharmacist about how long it's appropriate for you to take this.
Will this lower my blood pressure?
Animal research shows that forskolin, the active ingredient in coleus, may lower blood pressure. If you're already on blood pressure medication, this could be a problem — that's why it's critical to check with your doctor or pharmacist before starting.
Does coleus thin the blood?
Forskolin in coleus can inhibit how platelets stick together and clump, which theoretically raises the risk of bruising and bleeding if you're also on blood thinners or antiplatelet drugs. This is a Moderate-level concern and needs to be reviewed by your pharmacist or doctor.
