HelloPharmacist Scorecard of Chlorophyll by Swanson GreenFoods Formulas
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 has two active ingredients: alfalfa and chlorophyllin. Alfalfa is a plant commonly used in supplements; chlorophyllin is a semi-synthetic form of chlorophyll, the pigment that makes plants green.
Both are included here as sources of chlorophyll and related plant compounds. The capsule itself contains hypromellose and calcium palmitate as inactive ingredients to hold the formula together.
Does it work?
Couldn't assess
The evidence for what these ingredients do is limited. For alfalfa, the data we hold rates its effects on blood sugar, digestion, cholesterol, and menopausal symptoms as having insufficient evidence — meaning we don't have reliable studies to say whether it works for those purposes.
For chlorophyllin, odor control in urine is rated possibly ineffective, and its effects on acne, cancer, constipation, gas, and low white blood cell count are all rated insufficient evidence. In short, the ingredient claims made about this product are not well established in the scientific literature we reviewed.
How safe is it?
Well-documented data
Alfalfa is generally well tolerated when eaten in small food amounts, but supplements carry real risks for some people. The most common side effects from alfalfa supplements are abdominal discomfort, diarrhea, gas, and bulkier stools — particularly during the first week.
Rare serious effects include a lupus-like syndrome from long-term use and dermatitis (skin inflammation). Chlorophyllin is generally well tolerated short-term, but long-term safety data are sparse.
Oral chlorophyll can cause photosensitization and, in rare cases, pseudoporphyria (a blistering skin condition). During pregnancy, alfalfa supplements are possibly unsafe due to estrogen-like activity, and chlorophyllin should be avoided due to insufficient safety data.
While breastfeeding, alfalfa safety data are limited, so caution is advised; chlorophyllin safety is unknown, so avoidance is recommended. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant or nursing.
Meds to double-check
Major interaction found
Check with your doctor or pharmacist before taking this product if you use warfarin or another blood thinner — alfalfa can interfere with how well they work (Major severity). Also flag photosensitizing drugs, birth control, hormone therapy, immunosuppressants, and diabetes medications, all of which have moderate interactions documented.
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.
This product is not recommended if you take warfarin or other blood thinners — the interaction is serious. If you take birth control, hormone therapy, immunosuppressants, diabetes drugs, or medications that increase sun sensitivity, check with your doctor or pharmacist before starting.
The evidence for what alfalfa and chlorophyllin actually do is weak. Pregnancy and breastfeeding are concerns for both ingredients.

Chlorophyll by Swanson GreenFoods Formulas Drug Interactions
HelloPharmacist Interaction Report
Swanson GreenFoods Formulas Chlorophyll contains alfalfa and chlorophyllin, and both have documented interactions with medications.
The most serious concern is alfalfa with blood thinners like warfarin (Coumadin). Alfalfa is high in vitamin K, which can reduce how well warfarin works to prevent clots — a Major severity interaction that needs close monitoring if you take both.
Read the full breakdown — every affected drug type, severity by severity
Alfalfa also interacts moderately with photosensitizing drugs (drugs that make your skin more sun-sensitive), birth control pills, hormone therapy, drugs that suppress your immune system, and diabetes medications. The photosensitizing interaction is theoretically additive — meaning the effect on sun sensitivity could add up.
Birth control and hormone therapy may be less effective because alfalfa has estrogen-like compounds. Immunosuppressants may work less well.
And with diabetes drugs, there's a risk of low blood sugar (hypoglycemia), so blood glucose would need close watching.
Chlorophyllin — the other active ingredient — interacts moderately with photosensitizing drugs through the same mechanism: additive sun sensitivity risk. Altogether, these interactions span 583 individual medications.
Use the medication checker on this page to look up your exact drugs before starting. If you take warfarin, any hormone or immune medication, diabetes drugs, or anything that increases sun sensitivity, talk with your doctor or pharmacist first.

For each ingredient in Chlorophyll with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Alfalfa
Warfarin (Coumadin)
Theoretically, alfalfa might reduce the anticoagulant activity of warfarin.
Alfalfa contains a large amount of vitamin K. This could theoretically interfere with the activity of warfarin.
Antidiabetes Drugs
Theoretically, alfalfa might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that alfalfa decreases blood sugar in diabetic mice. Also, in one case report, a diabetic patient experienced hypoglycemia after consuming alfalfa extract. Monitor blood glucose levels closely. Dose adjustments might be necessary.
Contraceptive Drugs
Theoretically, alfalfa might interfere with the activity of contraceptive drugs.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.
Estrogens
Theoretically, alfalfa might interfere with hormone therapy.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.
Immunosuppressants
Theoretically, alfalfa might decrease the efficacy of immunosuppressive therapy.
In vitro research and human case reports suggest that alfalfa may have immunostimulant effects.
Photosensitizing Drugs
Theoretically, concomitant use of alfalfa with photosensitizing drugs might have additive effects.
Animal research suggests that excessive doses of alfalfa may increase photosensitivity, possibly due to its chlorophyll content. It is unclear if this effect would be clinically relevant in humans.
Chlorophyllin
Photosensitizing Drugs
Theoretically, concomitant use of chlorophyllin with photosensitizing drugs may have additive effects.
Chlorophyllin is a semi-synthetic derivative of chlorophyll. Chlorophyll has been reported to cause photosensitization. Orally, chlorophyll has also been associated with the development of pseudoporphyria in multiple case reports.
