HelloPharmacist Scorecard of Organic Alfalfa Powder by Micro Ingredients

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 Aug 27, 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: organic alfalfa powder. Alfalfa is a plant whose leaves have been used in traditional herbalism for various purposes, including supporting digestion and general wellness.

There are no inactive ingredients or fillers listed.

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 Alfalfa product and its label doesn't state a use — see Alfalfa'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 have doesn't establish that alfalfa reliably works for any of the conditions it's often used for—including blood sugar control, cholesterol, digestion, or menopausal symptoms. Our data rates all of these as having insufficient reliable evidence.

That doesn't mean alfalfa does nothing; it means good clinical trials backing these claims aren't on file with us.

The evidence, ingredient by ingredient Alfalfa

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.

Alfalfa leaf is generally well tolerated when eaten as food in small amounts, though a full safety review hasn't been done for supplement doses. The most common side effects are digestive—abdominal discomfort, diarrhea, gas, and bloating, especially during the first week of use.

Skin reactions (dermatitis) have been reported rarely with high doses taken over weeks. Very rarely, chronic use has been linked to a lupus-like syndrome.

During pregnancy, alfalfa's estrogen-like activity means the safety data advises against supplement doses. While breastfeeding, not enough safety data exists to know either way—talk it over with your doctor or pharmacist before using it.

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 — Alfalfa.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 583 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 taking this product, check with your doctor or pharmacist if you take warfarin or other blood thinners, birth control pills, hormone therapy, diabetes medications, immunosuppressants, or any drug that makes your skin sensitive to sunlight. The warfarin interaction is the most serious.

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.

Alfalfa powder might appeal to people looking for a plant-based supplement, but the evidence doesn't yet confirm it works for common uses like blood sugar or cholesterol. If you take warfarin, birth control, hormone therapy, diabetes medications, immunosuppressants, or photosensitizing drugs, you need to check with your own doctor or pharmacist before adding this—the interactions are real enough to matter.

Digestive side effects are common, especially at first.

organic Alfalfa powder6 drug types · 583 drugs

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.

Likelihood Probable Evidence D
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.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, alfalfa might interfere with the activity of contraceptive drugs.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.

Likelihood Possible Evidence D
Estrogens

Theoretically, alfalfa might interfere with hormone therapy.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, alfalfa might decrease the efficacy of immunosuppressive therapy.
In vitro research and human case reports suggest that alfalfa may have immunostimulant effects.

Likelihood Possible Evidence D
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.

Organic Alfalfa Powder by Micro Ingredients: Common Questions

Does Organic Alfalfa Powder by Micro Ingredients interact with any medications?
Yes. Based on its ingredients, Organic Alfalfa Powder has a known interaction with 583 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Alfalfa Powder 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.
Can I take alfalfa powder if I'm pregnant or breastfeeding?
During pregnancy, the safety data advises against alfalfa supplements because of its estrogen-like compounds. While breastfeeding, there isn't enough reliable safety data to know either way. Talk with your doctor or pharmacist before using it in either situation.
What are the common side effects?
Digestive upset is most common—abdominal discomfort, diarrhea, gas, and bloating often show up in the first week. Skin reactions have been reported rarely with high doses over several weeks.
Does alfalfa actually lower blood sugar?
Animal research and one patient case report suggest it might, but we don't have enough reliable human evidence yet to confirm it works. If you take diabetes medication, talk to your doctor before adding alfalfa—combining them could lower blood sugar too much.
Will alfalfa interfere with my birth control?
Alfalfa contains compounds with estrogen-like activity, which theoretically could reduce how well birth control works. If you take hormonal contraceptives, check with your doctor or pharmacist before starting this supplement.
Is alfalfa powder safe to take long-term?
A thorough long-term safety study hasn't been done. Very rarely, chronic use has been linked to a lupus-like syndrome, so if you're thinking about taking it regularly, talk it over with your doctor or pharmacist first.
